NOTES: 2. These parameters must be measured using pulse techniques, tp = 300 µs, duty cycle ≤ 2%.
3. These parameters must be measured using voltage-sensing contacts, separate from the current carrying contacts.
4. To obtain ft the [hFE] response is extrapolated at the rate of -6 dB per octave from f = 1 MHz to the frequency at which [hFE] = 1.
