Description
The STIEC45 Transil series has been designed to
protect DC power supply lines according to IEC
61000-4-5. This device protects circuits against
electrical fast transients (EFT) according to IEC
61000-4-4 and ETS EN 300 386. Protection
against electrostatic discharges is provided
according to IEC 61000-4-2 and MIL STD 883
Method 3015.
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.
The STIEC45 device is packaged in SMC (SMC
footprint in accordance with IPC 7351 standard).
