Product details
Overview
6DFN36A-M3/I from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, with 36 V nominal breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 49.9 V clamping voltage at 12 A peak pulse current, and 600 W peak pulse power (10/1000 μs). It protects MOSFETs and ICs in industrial sensor signal lines against lightning-induced transients.
For engineers reviewing the 6DFN36A-M3/I datasheet, 6DFN36A-M3/I pinout, 6DFN36A-M3/I application, or 6DFN36A-M3/I equivalent, key selection criteria include unidirectional polarity, low-profile DFN3820A footprint with side-wettable flanks for AOI, 175 °C max junction temperature, and IEC 61000-4-2 ±30 kV ESD immunity.
Technical Context
This device uses passivated anisotropic rectifier technology optimized for fast clamping response and low leakage. Its single-element configuration delivers precise voltage threshold control with ±5 % VBR tolerance and 0.090 %/°C temperature coefficient, enabling stable protection across -65 °C to +175 °C operating range.
The DFN3820A package provides 5 °C/W typical junction-to-mount thermal resistance and meets MSL Level 1 per J-STD-020 at 260 °C peak reflow. It is halogen-free, RoHS-compliant, and qualified to JESD 201 Class 2 whisker test standards.
