Product details
Overview
6DFN13CA-M3/H from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, with 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), and 33.0 A peak pulse current (IPPM). It protects sensitive ICs and MOSFETs against inductive switching transients and lightning surges in industrial sensor signal lines.
For engineers reviewing the 6DFN13CA-M3/H datasheet, 6DFN13CA-M3/H pinout, 6DFN13CA-M3/H application, or 6DFN13CA-M3/H equivalent, key selection criteria include clamping voltage (18.2 V at IPPM), low-profile DFN3820A footprint with side-wettable flanks for AOI, MSL Level 1 rating, and AEC-Q101 qualification indicated by /H suffix.
Technical Context
This device uses passivated anisotropic rectifier technology to deliver bidirectional clamping without polarity marking. Its junction passivation enables stable operation up to 175 °C maximum junction temperature and supports high-reliability industrial and automotive environments.
The DFN3820A package provides thermal resistance of 140–175 °C/W (junction-to-ambient) and 5–6.5 °C/W (junction-to-mount), enabling effective surge energy dissipation during 10/1000 μs transients while maintaining low capacitance for signal integrity on sensor and data lines.
Key Specifications

FAQ
What is the breakdown voltage tolerance of the 6DFN13CA-M3/H?
The 6DFN13CA-M3/H has a breakdown voltage tolerance of ±5 %, specified as 12.4 V (min) to 13.7 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise system-level surge margining in safety-critical designs.
Does the 6DFN13CA-M3/H require a cathode marking?
No-the 6DFN13CA-M3/H is a bidirectional TVS and carries no cathode band or polarity marking. Its symmetrical DFN3820A terminal structure allows installation in either orientation, simplifying PCB layout and reducing assembly errors in automated placement.
Is the 6DFN13CA-M3/H qualified for automotive applications?
Yes-the /H suffix in 6DFN13CA-M3/H indicates AEC-Q101 qualification. Vishay subjects this part to rigorous stress testing including HTGB, HTRB, temperature cycling, and ESD per AEC-Q101 Rev D, confirming suitability for automotive powertrain, body, and ADAS subsystems.
What is the maximum clamping voltage of the 6DFN13CA-M3/H at rated surge current?
The maximum clamping voltage (VC) of the 6DFN13CA-M3/H is 18.2 V at 33.0 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value defines the upper voltage limit imposed on protected circuits during worst-case transient events.
How does the DFN3820A package of the 6DFN13CA-M3/H support automated optical inspection?
The DFN3820A package of the 6DFN13CA-M3/H features side-wettable flanks-exposed copper terminations along the package edges-that reflect light uniformly during AOI. This enables reliable solder-joint verification without X-ray, improving first-pass yield in high-volume SMT lines.
