SMDJ-HR Series

AGENCY AGENCY FILE NUMBER

E230531

The SMDJ-HR High Reliability series is designed

specifically to protect sensitive electronic equipment from

voltage transients induced by lightning and other transient

voltage events.

C per Fig. 2.

2. Mounted on copper pad area of 0.31x0.31” (8.0 x 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.
