Electrical Performance Criteria:

Transistor topology: PNP Darlington configuration
Maximum collector current: 1 A
Collector-emitter breakdown voltage: 80 V
Saturation voltage: 1.3 V @ 500µA, 500mA
DC current gain (hFE): minimum 2000 @ 500mA, 10V
Maximum power dissipation: 1.25 W
Transition frequency: 200 MHz
Collector cutoff current: 50 nA maximum

Mechanical & Environmental Criteria:

Surface mount packaging in SOT-223 form factor
TO-261-4 or TO-261AA case designation
Operating temperature range to 150°C (TJ)
Automotive grade qualification per AEC-Q101
