Panasonic 2SA1773E-E

The 2SA1773E is a PNP epitaxial planar silicon transistor designed for high-voltage driver applications, with a collector-to-emitter voltage rating of 400 V and a continuous collector current of 2 A. It is housed in a TO-92 package with dimensions of 5.0 mm × 6.5 mm × 2.3 mm. The device has a DC current gain (hFE) range of 100 to 200, as designated by the E rank, and a gain-bandwidth product of 60 MHz. The junction temperature rating is 150 °C, and it operates within a storage temperature range of -55 °C to +150 °C. The transistor meets RoHS compliance and is intended for general electronics equipment, not for life-sustaining or safety-critical systems.
