Maximum Ratings and Electrical Characteristics

Ratings at 25℃ ambient temperature unless otherwise specified.

Single phase, half wave, 60HZ, resistive or inductive load.

For capacitive load, derate current by 20%.

Peak power dissipation with a 10/1000µs waveform (Note 1 , 2) (Fig. 1)

Peak pulse current with a 10/1000µs waveform (Note 1) (Fig. 3)

Power dissipation on infinite heatsink, TA = 50°C

Peak forward surge current, 8.3ms

single half sine-wave unidirectional only (Note 2)

Maximum instantaneous forward voltage

at 25A for unidirectional only (Note 4)

Thermal resistance junction to leads

Thermal resistance junction to ambient air (Note 3)

Operating junction and storage temperature range

NOTES:

1- Non-repetitive current pulse, per Fig. 3 and derated above TA = 25°C per Fig. 2. Rating is 300W above 91V.

2- Mounted on 0.2 x 0.2” (5.0 x 5.0mm) copper pads to each terminal

3- Mounted on minimum recommended pad layout

4- VF = 3.5V for P4SMA200(A) & below; VF = 6.5V for P4SMA220(A) & above

Devices for Bidirectional Applications:

1- For bi-directional, use C or CA suffix for types P4SMA6.8 thru types P4SMA440A(e.g. P4SMA6.8C, P4SMA440CA).

2- Electrical characteristics apply in both directions.
