Product details
Overview
T6N36CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, featuring 36 V nominal breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 49.9 V maximum clamping voltage at 12 A peak pulse current, and 600 W peak pulse power rating (10/1000 μs). It is AEC-Q101 qualified and rated for TJ = 185 °C, designed for automotive sensor signal-line protection against inductive switching transients.
For engineers reviewing the T6N36CAHM3/I datasheet, T6N36CAHM3/I pinout, T6N36CAHM3/I application, or T6N36CAHM3/I equivalent, this page delivers verified electrical parameters, package dimensions, automotive-grade reliability context, and direct alternative part comparisons - all specific to the T6N36CAHM3/I variant with HM3 halogen-free, RoHS-compliant, leadless DFN construction.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and low-leakage performance. Its bidirectional configuration enables symmetrical clamping without polarity constraints, and its DFN3820A package supports AOI-compatible side-wettable flanks for automated optical inspection in high-reliability SMT lines.
The device operates across -65 °C to +185 °C junction temperature range and meets IEC 61000-4-2 ESD immunity up to ±30 kV (contact/air discharge). Thermal resistance is specified as RθJA = 175 °C/W (max) and RθJM = 6.5 °C/W (max), enabling effective heat dissipation in compact automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 34.2 / 36.0 / 37.8 V - ensures reliable conduction onset above system operating voltage while accommodating ±5 % tolerance |
| VWM | 30.8 V - maximum continuous reverse working voltage before leakage exceeds 1 μA at 25 °C |
| VC @ IPPM | 49.9 V at 12 A - clamping voltage during 10/1000 μs surge, limiting downstream IC stress to safe levels |
| PPPM | 600 W - peak pulse power handling capability under standardized 10/1000 μs waveform |
| TJ max | +185 °C - enables operation in under-hood automotive environments without derating penalties |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/57T | DO-214AC (SMA) package, 36 V unidirectional, 400 W PPPM, higher RθJA (~190 °C/W) | Requires polarity-aware layout; unsuitable for AC or floating signals without external biasing | Select when legacy SMA footprint compatibility is required and unidirectional clamping suffices |
| SMCJ36CA | DO-214AB (SMC) package, 36 V bidirectional, 1500 W PPPM, larger 7.11 mm × 6.22 mm footprint | Higher surge capacity but incompatible with space-constrained automotive PCBs | Select when >600 W surge margin is mandatory and board area permits larger SMC package |
Compared with SMAJ36A-E3/57T and SMCJ36CA, the T6N36CAHM3/I uniquely combines AEC-Q101 qualification, DFN3820A miniaturization, side-wettable flanks for AOI, and precise 600 W/36 V bidirectional clamping - making it optimal for next-generation automotive sensor nodes where size, reliability, and manufacturability are co-constrained.

FAQ
What is the breakdown voltage tolerance of the T6N36CAHM3/I?
The T6N36CAHM3/I has a ±5 % breakdown voltage tolerance, confirmed by its "CA" suffix per Vishay's ordering nomenclature. Its VBR is specified as 34.2 V (min), 36.0 V (nominal), and 37.8 V (max) at 1.0 mA test current - ensuring consistent clamping behavior across production lots and temperature ranges.
Is the T6N36CAHM3/I suitable for automotive applications?
Yes, the T6N36CAHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and JESD201 Class 2 whisker-resistant construction. Its 185 °C maximum junction temperature and ±30 kV ESD rating make it appropriate for under-hood and cabin-mounted automotive electronics.
What does the "HM3" suffix mean in T6N36CAHM3/I?
The "HM3" suffix in T6N36CAHM3/I denotes AEC-Q101 qualification (H), halogen-free/RoHS-compliant materials with Pb-free terminations (M), and compliance with JESD201 Class 2 whisker testing (3). It also indicates packaging in 13″ tape-and-reel (I) with 14,000-unit base quantity.
Does the T6N36CAHM3/I require a heatsink for 600 W surge handling?
No, the T6N36CAHM3/I is rated for 600 W peak pulse power (10/1000 μs) without external heatsinking. Its DFN3820A package achieves RθJM = 6.5 °C/W (max) to the PCB mount pad, enabling sufficient thermal transfer via standard 2 oz. copper land patterns - verified per JEDEC 51-14 methodology.
How does the T6N36CAHM3/I compare to standard SMA/SMB packaged TVS diodes?
The T6N36CAHM3/I replaces larger SMA/SMB packages with a 2.18 mm × 3.95 mm DFN3820A footprint, offers side-wettable flanks for AOI, achieves lower profile (0.88 mm), and maintains AEC-Q101 qualification - whereas most SMA/SMB TVS parts lack automotive qualification or AOI support despite similar electrical specs.
