Product details
Overview
T6N22CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, featuring 22.0 V nominal breakdown voltage (VBR), 18.8 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs), designed for automotive-grade ESD and surge protection of sensor signal lines and MOSFET gates.
For engineers reviewing the T6N22CAHM3/I datasheet, T6N22CAHM3/I pinout, T6N22CAHM3/I application, or T6N22CAHM3/I equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal derating curves, clamping behavior at 19.6 A IPPM, and direct replacement guidance for automotive electronics protection design.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for high-reliability operation up to TJ = 185 °C. Its bidirectional configuration enables symmetrical clamping on both polarities without polarity marking.
The DFN3820A package features side-wettable flanks for automated optical inspection (AOI) and supports reflow soldering at 260 °C peak (MSL Level 1). It delivers 30.6 V maximum clamping voltage at 19.6 A peak pulse current under 10/1000 μs waveform conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22CAHE3/5AT | DO-214AC (SMA) package, 22 V VBR, 600 W PPPM, but larger footprint and no AEC-Q101 qualification | Non-automotive industrial boards where board space and qualification are not constrained | Select when legacy SMA layout exists and automotive qualification is unnecessary |
| SMCJ22CAHM3 | DO-214AB (SMC) package, same VBR/PPPM, AEC-Q101 qualified, but 2.5× larger footprint and higher RθJA | High-power automotive subsystems requiring >600 W headroom or existing SMC footprints | Select only if thermal budget allows higher junction rise or PCB real estate permits larger case |
Compared with SMAJ22CAHE3/5AT and SMCJ22CAHM3, the T6N22CAHM3/I offers superior space efficiency (DFN3820A vs. SMA/SMC), lower thermal resistance to mount (5 °C/W), and guaranteed AOI compatibility-making it optimal for next-generation automotive ECUs where miniaturization and process yield are critical.
