Note 3. These parameters must be measured using pulse techniques, tw = 300µs, duty cycle ≤ 2%.
Note 4. These parameters are measured with voltage–sensing contacts separate from the current–
carrying contacts located within 1/8” (3.2mm) from the device body.
Note 5. Voltage and current values shown are nominal; exact values vary slightly with transistor pa-
rameters.
