9 / 17 page TPIC6A595 POWER LOGIC 8BIT SHIFT REGISTER SLIS005B − APRIL 1993 − REVISED MAY 2005 9 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 PARAMETER MEASUREMENT INFORMATION + − 2500 µF 250 V L = 1 mH IF (see Note B) RG VGG (see Note A) Driver TP A 50 Ω Circuit Under Test DRAIN 24 V t1 t3 t2 TP K TEST CIRCUIT 0.35 A IF 0 IRM (see Note C) 25% of IRM ta trr di/dt = 20 A/ µs CURRENT WAVEFORM NOTES: A. The VGG amplitude and RG are adjusted for di/dt = 20 A/µs. A VGG double-pulse train is used to set IF = 0.35 A, where t1 = 10 µs, t2 = 7 µs, and t3 = 3 µs. B. The DRAIN terminal under test is connected to the TP K test point. All other terminals are connected together and connected to the TP A test point. C. IRM = maximum recovery current Figure 5.

NOTES: A. The word generator has the following characteristics: tr ≤ 10 ns, tf ≤ 10 ns, ZO = 50 Ω. B. Input pulse duration, tw, is increased until peak current IAS = 600 mA. Energy test level is defined as EAS = (IAS × V(BR)DSX × tav)/2 = 75 mJ. Figure 6. Single-Pulse Avalanche Energy Test Circuit and Waveforms |
