1. Non-repetitive current pulse per Figure 5 and derate above TA = 25°C per Figure 4.

2. Non-repetitive current pulse per Figure 6 and derate above TA = 25°C per Figure 4.

3. FR-5 = 1.0 x 0.75 x 0.62 in.

4. Alumina = 0.4 x 0.3 x 0.024 in., 99.5% alumina

5. VZ measured at pulse test current IT at an ambient temperature of 25°C.

6. Surge current waveform per Figure 5 and derate per Figure 4.

7. ZZT is measured by dividing the AC voltage drop across the device by the AC current supplied. The specified limits are IZ(AC) = 0.1 IZ(DC),

with AC frequency = 1 kHz.
