Microsemi Corp. Bipolar Transistors - BJT Jantx2N2946A/TR

The Jantx2N2946A/TR is a PNP silicon small signal transistor in a TO-46 metal can package, qualified to JANTX level per MIL-PRF-19500/382 for high-reliability applications. It has a collector-to-emitter voltage rating of -35 V, a collector current of -100 mA, and a total power dissipation of 400 mW at +25°C, derating linearly at 2.30 mW/°C above that temperature. The thermal resistance junction-to-ambient is 435°C/W. The device meets MIL-STD-750, method 1020, for ESD class 3 and is constructed with a nickel-plated kovar case, gold-plated terminals, and glass seals. The package dimensions are standardized for the series, with emitter, base, and collector leads on pins 1, 2, and 3 respectively. The JANTXV variant is also available but not applicable to this part number.
