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.
