Motorola wasn't giving away databooks in the seventies so I had to wait until I had $40 extra to buy a set from them in 1980. pdf 2N37712N3772HIGH POWER NPN SILICON TRANSISTOR STMicroelectronics PREFERREDSALESTYPESDESCRIPTION The 2N3771, 2N3772 are silicon epitaxial-baseNPN transistors mounted in Jedec Jedec TO-3metal case. If your The first higher voltage 'version' of 2N3055 was 2N3442 > right up to 140V vce, BUT only 10A . Cheers, Chris . So a total of two boards are necessary to form a dual direction servo unit (Each amp uses a total of 12 2N3773's for a total of 90 Amps at 90Vdc, at full load when the trannies are completely either on or off depending on the direction of rotation) all the original devices on the amp were ok, except two that were shorted. Breakdown This below compares each of the identical transistors, such as 2n3055 vs 2n3773, 2n3055 vs 2n3773, 2n3055 vs tip3055 and 2n3055 vs 2n3771. One of BOB PEASE's trouble shooting books has a brief but accurate write up on the RCA hometaxial BJT process. Hooked up the class H rail switches and EVERY time the The 2N3773 is a power transistor designed for high power audio, disk head positioners and other linear applications. JPG. Because of its strong switching capability, this power transistor is also used in power-switching circuits like relays, DC-DC converters, and solenoid drivers. google. 128.
