Microsemi Corp. Bipolar Transistors - BJT 2N2945A/TR

The 2N2945A is a PNP silicon small signal transistor qualified to JANTX and JANTXV levels for high-reliability applications, housed in a TO-46 (TO-206AB) metal can package measuring 12.70 mm to 44.45 mm in length. It has a collector-emitter voltage rating of -20 V, a collector current of -100 mA, and a total power dissipation of 400 mW at +25 °C, derating at 2.30 mW/°C above that temperature. The thermal resistance junction-to-ambient is 435 °C/W. It is RoHS compliant in commercial grade versions and meets MIL-PRF-19500/382 qualification standards with ESD protection to Class 3 per MIL-STD-750, method 1020.
