Notes:

1. Non-repetitive current pulse , per Fig. 4 and derated above T

= 25°C per Fig. 3.

2. Mounted on copper pad area of 0.31x0.31” (8.0 × 8.0mm) to each terminal.

3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional

device only, duty cycle=4 per minute maximum.

TVS devices are ideal for the protection of I/O Interfaces,

bus and other vulnerable circuits used in Telecom,

Computer, Industrial and Consumer electronic applications.
