Npn transistor part numbers Each transistor has a part number. Search within results Enter a part number or keyword. The 2N2222 is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. "BD" for a power transistor), then a letter or letter/number combination to give the case+pinout type, e. But 4N and 5N are reserved for opto-couplers. The “A” suffix indicates that it is a higher-performance version of the original 2N2222 device. g. [7] [8] [9] The 2N2222 was part of a family of devices described by Motorola at a 1962 IRE These part numbers take the form: digit, two letters, sequential number, [optional suffix] Digits are 1 for diodes, 2 for transistors, and so forth. Codes beginning with 2N, for example 2N3053. Jan 14, 2010 · Transistors and diodes would start with a 2-letter prefix based on the Pro Electron standard (e. The letter at the end identifies versions with different voltage ratings. Feb 21, 2023 · BC817 - a low-power NPN transistor with a maximum collector current of 0. MPS Transistors Specifications. NPN SILICON HIGH FREQUENCY TRANSISTOR DESCRIPTION: The CENTRAL SEMICONDUCTOR 2N3866 and 2N3866A are Silicon NPN RF Transistors, mounted in a hermetically sealed package, designed for high frequency amplifier and oscillator applications. If the part number of the transistor is known, it would be better to identify it by its part number. There is no obvious logic to the numbering numbers: The part number and the date code. Part No. com These parts are optimised for use in a given part of a given circuit. In the photo below, two different transistors are shown. The letters indicate the type and intended application of the device according to the following code . Nxp bt136-600d triacs rail triac, dip, npn; 1002 smd transistor, npn; Tip122 - npn transistor - switching transistor - fr-05-624; Transistor tp-142; Toshiba 15a 2sa1943 npn transistor, for ups,ac inverter driv Cdil bc547 npn transistor; St smd transistor lm317mdt-tr, npn; Working of transistor/NPN transistor Aug 14, 2024 · The “2N” prefix indicates that it is a JEDEC-registered part number, while the “2222” is a specific device number assigned by the manufacturer. It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. The value of Beta for most standard NPN transistors can be found in the manufactures data sheets but generally range between 50 – 200. BC846 - a low-power NPN transistor with a maximum collector current of 0. Often when a company goes bankrupt, or has surplus at the end of a production run, these transistors find their way into hobbyist bargain packs. The JEDEC EIA370 transistor device numbers usually start with "2N", indicating a three-terminal device (dual-gate field-effect transistors are four-terminal devices, so begin with 3N), then a 2, 3 or 4-digit sequential number with no significance as to device properties (although early devices with low numbers tend to be germanium). MARKING: FULL PART NUMBER MAXIMUM RATINGS: (TA=25°C unless otherwise noted) SYMBOL UNITS The values of Beta vary from about 20 for high current power transistors to well over 1000 for high frequency low power type bipolar transistors. Package NPN/PNP Ic (mA) Pd (mW) Vce (max) Vcb (max) hfe @ Ic FT (MHz) Complement Appl Datasheet; MPS651: Apr 7, 2021 · ID numbers or part numbers on the transistor tells what specific part it is, so looking it up reveals what it is and you can read the datasheet about important parameters. 080 42650011. NPN Transistors are available at Mouser Electronics. Dec 21, 2017 · Here is a link that shows various package sizes for 3904 transistors. Since the 2N3904 is an NPN transistor, the base needs positive biasing (appropriate voltage levels and resistance) to turn on the collector emitter junction for proper current flow. 5A and a maximum voltage of 45V, commonly used in low-power amplification and switching applications. The initial '2N' identifies the part as a transistor and the rest of the code identifies the particular transistor. 1A and a maximum voltage of 65V, commonly used in low-power amplification and switching applications. For example Jan 20, 2025 · To tell whether a transistor is an NPN or PNP type, identify it by its part number or check it with a tester. The circuit around the transistor and how it is used may reveal clues about the type what it could be, or at least what it can't be. They usually just have a manufacturers stamp and an untraceable number. See full list on fscdn. They have the part numbers 2N2222 and KSP2222 (also available as PN2222). TIP refers to the manufacturer: Texas Instruments Power transistor. "K" for TO-3 with the standard CBE pinout (or DGS for FETs), then "N" for NPN or "P" for PNP, or even NNPP for a package with two . Skip to Main Content. Mouser offers inventory, pricing, & datasheets for NPN Transistors. Joint Electron Device Engineering Council (JEDEC) These part numbers take the form: digit, letter, sequential number, [suffix] The letter is always 'N', and the first digit is 1 for diodes, 2 for transistors, 3 for four-leaded devices, and so forth. Jul 30, 2012 · These are the names of the packages and not the transistor part numbers. rohm. 1. The bigger the package is, the more power the transistor can handle. There are four types of transistor part numbers, starting with 2SA, 2SB, 2SC, and 2SD respectively.
