STIEC45-xxAS, STIEC45-xxACS Transil TVS for IEC 61000-4-5 compliance Datasheet - production data MIL STD 883G, method 3015-7 Class 3B 25 kV HBM (human body model) Resin meets UL 94, V0 MIL-STD-750, method 2026 solderability EIA-481 and IEC 60286-3 packing IPC 7531 footprint 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 Features provided according to IEC 61000-4-2 and MIL Peak pulse current: 500 A (1.2/50 s, STD 883 Method 3015. 8/20 s) Stand-off voltage range: from 24 V to 33 V Planar technology makes these devices suitable Unidirectional types: STIEC45-xxAS for high-end equipment and SMPS where low Reverse: Clamping starts at VBR leakage current and high junction temperature are required to provide reliability and stability Forward: Clamping starts around 0.6 V over time. Bidirectional types: STIEC45-xxACS Clamping starts at V on both BR The STIEC45 device is packaged in SMC (SMC directions footprint in accordance with IPC 7351 standard).
