Description
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).
Complies with the following standards
■
IEC 61000-4-2 level 4 – 15 kV (air discharge) – 8 kV (contact discharge) IEC 61000-4-5 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 STD RS-481 and IEC 60286-3 packing IPC 7531 footprint
