Specifications are subject to change without notice.

BD546 Series

absolute maximum ratings at 25°C case temperature (unless otherwise noted)

NOTES: 1. These values apply when the base-emitter diode is open circuited.

2. Derate linearly to 150°C case temperature at the rate of 0.68 W/°C.

3. Derate linearly to 150°C free air temperature at the rate of 28 mW/°C.
