Type: NPN Collector-Emitter Voltage: 60 V Collector-Base Voltage: 100 V Emitter-Base. Type: NPN + PNP Transistor Category: Power Transistor. But in PNP transistors, the condition will be just reversed. Maximum Base-Emitter Voltage: 100 V Number of Pins: 2 Series: 2N3055 + MJ2955.

Here is a picture: I think it might be a 2N5038 (which most sites list as an NPN, although I found a General Diode datasheet which lists a 2N5038 as a PNP in a TO3 package), but I'm just not sure. How to Identify the Pins of 2N3055 Transistor - YouTube. In most NPN transistors it will be 1 (Collector), 2 (Base) and 3 ( Emitter ). To me that suggests that this is an NPN with a burned out base-emitter junction. In testing this transistor (out of the circuit) with a multimeter, I measure a very low resistance when the common probe is on the collector and the positive probe is on the base, and a very high resistance in any other configuration. It's supposed to be the PNP in the output stage, the NPN is a 2N3055 which appears to work fine.

I have a TO-3 package transistor that I pulled out of an EHX Mike Matthews Dirt Road Special (schematic attached). Personal Identification Number (PIN) is assigned to you to speed up ordering of faxes.
