The SMCJ 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 more generally used against surges
below 1500 W (10/1000 μs).
The Planar technology makes it compatible with
high-end equipment and SMPS where low
leakage current and high junction temperature are
required to provide reliability and stability over
time.
SMCJ are packaged in SMC (SMC footprint in
accordance with IPC 7531 standard).

1. Pulse test : tp < 50 ms
2. To calculate maximum clamping voltage at other surge level,use the following formula: VCLmax = VCL - RD x (IPP - IPPappli)
where IPPappli is the surge current in the application
3. To calculate VBR or VCL versus junction temperature, use the following formulas:
VBR @ TJ = VBR @ 25°C x (1 + αT x (TJ – 25))
VCL @ TJ = VCL @ 25°C x (1 + αT x (TJ – 25))
4. Surge capability given for both directions for unidirectional and bidirectional types.
