Product Overview

The Transil SMBJ series from STMicroelectronics are transient voltage suppressing diodes. These diodes are used to protect sensitive equipment against electrostatic discharges and electrical over stress. Transil SMBJ series are generally used against surges below 600W (10/1000 μs). Planar technology makes these devices suitable for high end equipment and SMPS where low leakage current and high junction temperature are required. These devices are packaged in SMB footprint in accordance with IPC 7531 standard.
  • High reliability and stability
  • Peak pulse power of 600W at 10/1000μs and 4KW at 8/20μs
  • Standoff voltage range from 5V to 188V
  • Available in unidirectional and bidirectional types
  • Operating temperature range -55°C to 150°C
  • High power capability of 515W
  • Compliant IEC 61000-4-2 level 4, IEC 61000-4-5, UL 94, EIA STD RS-481 and IEC 60286-3 standards
  • Meets MIL STD 883G, MIL-STD-750 standards
