Product details
Overview
6DFN36CA-M3/H from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, with 36 V nominal breakdown voltage (VBR = 34.2–37.8 V), 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 signal lines in sensor units and MOSFET gate drivers against lightning-induced transients and inductive switching surges.
For engineers reviewing the 6DFN36CA-M3/H datasheet, 6DFN36CA-M3/H pinout, 6DFN36CA-M3/H application, or 6DFN36CA-M3/H equivalent, key selection criteria include bidirectional clamping capability, low-profile DFN3820A footprint with side-wettable flanks for AOI, M3 halogen-free/RoHS-compliant termination, and 175 °C maximum junction temperature for industrial-grade reliability.
Technical Context
This device uses passivated anisotropic rectifier technology to deliver stable bidirectional clamping without polarity marking. Its DFN3820A package enables high-density PCB layout while supporting automated optical inspection via side-wettable flanks and meeting J-STD-020 MSL Level 1 with 260 °C reflow peak.
The 6DFN36CA-M3/H operates across -65 °C to +175 °C junction temperature range, exhibits 1.0 μA max reverse leakage at VWM, and achieves 5–6.5 °C/W junction-to-mount thermal resistance per JEDEC 51-14 TDIM testing-critical for sustained surge handling in compact power interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 34.2 / 36.0 / 37.8 V - ensures reliable conduction onset above 30.8 V operating voltage, preventing false triggering during normal operation |
| VWM | 30.8 V - maximum continuous working voltage before clamping begins; defines safe DC/AC signal line operating margin |
| VC @ IPPM | 49.9 V at 12.0 A - clamping voltage under 10/1000 μs surge; limits protected circuit stress to ≤50 V during worst-case transients |
| PPPM | 600 W - peak pulse power rating determines survivability against standardized lightning/surge waveforms (IEC 61000-4-5) |
| TJ max | +175 °C - enables use in under-hood automotive, industrial motor drives, and high-ambient embedded systems without derating |
| ESD immunity | ±30 kV contact/air (IEC 61000-4-2) - provides robust protection for human-touch interfaces and exposed connectors |
| Package | DFN3820A (3.95 × 2.18 × 0.88 mm) - ultra-low profile with side-wettable flanks supports AOI and high-volume SMT assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/57T | DO-214AC (SMA) package; 36 V unidirectional; 400 W PPPM; higher VC = 58.1 V at 6.9 A | Requires polarity-aware placement; larger footprint (4.5 × 2.7 mm); lower surge rating limits use in high-energy industrial environments | Select when legacy SMA layout exists and bidirectionality is not required; avoid where space-constrained or AOI is mandated |
| SMCJ33CA | DO-214AB (SMC) package; 33 V bidirectional; 1500 W PPPM; VC = 53.3 V at 28.3 A; taller profile (2.6 mm) | Higher power handling but incompatible with DFN-restricted board space; lacks side-wettable flanks for AOI | Choose for higher-energy surge environments where board area allows; not suitable for ultra-thin or high-density consumer/automotive modules |
