1N5908 SM5908 Transil Features Peak pulse power: 1500 W (10/1000 s) A Stand off voltage: 5 V A Unidirectional Operating T : 175 C jmax K K High power capability at T : jmax SMC DO-201 1500 W (10/1000 s) (JEDEC DO-214AB) JEDEC registered package outline Complies with the following standards IEC 61000-4-2 level 4: 15 kV (air discharge) Description 8 kV (contact discharge) This Transil series has been designed to protect IEC 61000-4-5 sensitive equipment against electrostatic MIL STD 883G, method 3015-7 Class 3B discharges according to IEC 61000-4-2, and 25 kV HBM (human body model) MIL STD 883, method 3015, and electrical over stress according to IEC 61000-4-4 and 5. These Resin meets UL 94, V0 devices are more generally used against surges MIL-STD-750, method 2026 solderability below 1500 W (10/1000 s). EIA STD RS-481 and IEC 60286-3 packing The Planar technology makes it compatible with IPC 7531 footprint high-end equipment and SMPS where low leakage current and high junction temperature are required to provide reliability and stability over time. They are packaged in SMC (SMC footprint in accordance with IPC 7531 standard) and DO-201.
