Description

The SMAJ Transil series has been designed to

protect sensitive equipment against electrostatic

discharges according to IEC 61000-4-2, and

MIL STD 883, method 3015, and electrical over

stress according to IEC 61000-4-4 and 5. These

devices are generally used against surges below

400 W (10/1000 μs).

Planar technology makes these devices suitable

for high-end equipment and SMPS where low

leakage current and high junction temperature are

required to provide reliability and stability over

time.

SMAJ are packaged in SMA (SMA footprint in

accordance with IPC 7531 standard).
