SMA6J Datasheet High junction temperature Transil Features Peak pulse power: A A 600 W (10/1000 s) 4 kW (8/20 s) K K Stand-off voltage range: from 5 V to 188 V Unidirectional and bidirectional types Unidirectional Bidirectional Low leakage current: SMA (JEDEC DO-214AA) 0.2 A at 25 C 1 A at 85 C Operating T max: 175 C j JEDEC registered package outline Complies with the following standard: IEC 61000-4-2 level 4: 15 kV (air discharge) 8 kV (contact discharge) Complies with the following standard: MIL STD 883G, method 3015-7, class 3B: 25 kV HBM (human body model) Description The SMA6J Transil series has been designed to protect sensitive equipment against electro-static discharges according to IEC 61000-4-2, MIL STD 883 Method 3015, and electrical overstress such as IEC 61000-4-4 and 5. They are generally for surges Product status link below 600 W 10/1000 s. SMA6J This 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. Their low clamping voltages provide a better safety margin to protect sensitive circuits with extended life time expectancy. Packaged in SMA, which minimizes PCB space consumption (SMA footprint in accordance with IPC 7531 standard). Transil is a trademark of STMicroelectronics.
