Product Overview

The Transil SMM4F series high junction temperature TVS Diode designed to protect sensitive equipment against electrostatic discharges according to IEC 61000-4-2, MIL STD 883 Method 3015 and electrical over stress such as IEC 61000-4-4 and 5. It is generally used for surges below 400W 10/1000µs. The 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.
  • 5 to 33V Stand off voltage range
  • Unidirectional types
  • 0.2µA at 25°C and 1µA at 85°C Low leakage current
  • -55 to 175°C Operating junction temperature range
