1 January 2018 DocID5616 Rev 11 1/11 This is information on a product in full production. SMBJ Transil Datasheet - production data Features Peak pulse power: 600 W (10/1000 s) 4 kW (8/20 s) Stand-off voltage range: from 5 V to 188 V Unidirectional and Bidirectional types Low leakage current: A at 25 C 1 A at 85 C Operating Tj max: 150 C High power capability at Tj max: 515 W (10/1000 s) JEDEC registered package outlineComplies 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.

2 Class 3B: 25 kV HBM (human body model) Resin meets UL 94, V0 MIL-STD-750, method 2026 soldererability EIA STD RS-481 and IEC 60286-3 packing IPC 7531 footprintDescription The SMBJ 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 600 W (10/1000 s). 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.

3 SMBJ are packaged in SMB (SMB footprint in accordance with IPC 7531 standard). Transil is a trademark of STMicroelectronics.
