absolute maximum ratings at 25°C case temperature (unless otherwise noted)
NOTES: 1. This value applies for tp ≤ 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, IB(on) = 0.4 A, RBE = 100 Ω,
VBE(off) = 0, RS = 0.1 Ω, VCC = 20 V.

PRODUCT INFORMATION
NOTES: 5. These parameters must be measured using pulse techniques, tp = 300 µs, duty cycle ≤ 2%.
6. These parameters must be measured using voltage-sensing contacts, separate from the current carrying contacts.
† Voltage and current values shown are nominal; exact values vary slightly with transistor parameters.

PRODUCT INFORMATION
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.
