STIEC45-28ACS数据手册电路保护的TVS-二极管规格书PDF

描述 Description

The STIEC45 Transil series has been designed to protect DC power supply lines according toIEC 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 isprovided 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 lowleakage current and high junction temperature are required to provide reliability andstability over time.
The STIEC45 device is packaged in SMC (SMC footprint in accordance with IPC 7351standard).
