SMBJ Transil Features Peak pulse power: 600 W (10/1000 s) A 4 kW (8/20 s) Stand off voltage range: from 5 V to 188 V Unidirectional and bidirectional types K Unidirectional Bidirectional Low leakage current: SMB 0.2 A at 25 C (JEDEC DO-214AA) 1 A at 85 C Operating T : 150 C jmax High power capability at T : jmax 515 W (10/1000 s) Description JEDEC registered package outline The SMBJ Transil series has been designed to Complies with the following standards protect sensitive equipment against electrostatic IEC 61000-4-2 level 4: discharges according to IEC 61000-4-2, and MIL STD 883, method 3015, and electrical over 15 kV (air discharge) stress according to IEC 61000-4-4 and 5. These 8 kV (contact discharge) devices are more generally used against surges IEC 61000-4-5 below 600 W (10/1000 s). MIL STD 883G, method 3015-7 Class 3B: Planar technology makes these devices suitable 25 kV HBM (human body model) for high-end equipment and SMPS where low Resin meets UL 94, V0 leakage current and high junction temperature are required to provide reliability and stability over MIL-STD-750, method 2026 soldererability time. EIA STD RS-481 and IEC 60286-3 packing SMBJ are packaged in SMB (SMB footprint in IPC 7531 footprint accordance with IPC 7531 standard).
