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).
