NOTES: 1. This value applies for t p £ 0.3 ms, duty cycle £ 10%.

2. Derate linearly to 150°C case temperature at the rate of 0.32 W/°C.

3. Derate linearly to 150°C free air temperature at the rate of 16 mW/°C.

4. This rating is based on the capability of the transistor to operate safely in a circuit of: L = 20 mH, I B(on) = 0.4 A, R BE = 100 W ,

V BE(off) = 0, R S = 0.1 W , V CC = 20 V.

MECHANICAL DATA

TO-220

3-pin plastic flange-mount package

This single-in-line package consists of a circuit mounted on a lead frame and encapsulated within a plastic

compound. The compound will withstand soldering temperature with no deformation, and circuit performance

characteristics will remain stable when operated in high humidity conditions. Leads require no additional

cleaning or processing when used in soldered assembly.
