Product details
Overview
T6N39CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 39 V nominal breakdown voltage (±5 %), 33.3 V stand-off voltage, 53.9 V clamping voltage at 11.1 A peak pulse current, and 600 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified for automotive sensor line protection against inductive switching transients and lightning surges.
For engineers reviewing the T6N39CAHM3/H datasheet, T6N39CAHM3/H pinout, T6N39CAHM3/H application, or T6N39CAHM3/H equivalent, this page delivers verified electrical specs, thermal performance (TJ = 185 °C), AOI-compatible leadless packaging, and direct substitution guidance for automotive-grade TVS selection.
Technical Context
This device employs passivated anisotropic rectifier technology to achieve stable bidirectional clamping under repetitive surge stress. Its DFN3820A package features side-wettable flanks and meets MSL Level 1 (260 °C peak reflow), enabling high-yield automated assembly in automotive PCBs.
Designed for operation from −65 °C to +185 °C junction temperature, it delivers 30 kV ESD immunity per IEC 61000-4-2 (contact/air discharge) and maintains ≤1.0 μA reverse leakage at VWM up to 150 °C - critical for long-term reliability in engine bay and ADAS modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 37.1 / 39.0 / 41.0 V - ensures robust overvoltage triggering margin above system rail during transient events |
| VWM | 33.3 V - maximum continuous operating voltage before leakage exceeds 1.0 μA at 25 °C |
| VC @ IPPM | 53.9 V at 11.1 A - clamping voltage limits downstream IC stress during 10/1000 μs surge |
| PPPM | 600 W - peak pulse power handling capability compliant with ISO 7637-2 and SAE J1113-11 |
| TJ max | +185 °C - enables placement near high-temperature zones (e.g., powertrain ECUs) without derating |

Applications
| Automotive Sensor Protection | Power Supply Rail Clamping |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load-dump and inductive kickback in 12 V vehicle networks. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector entry point to clamp ±50 V transients before reaching signal conditioning circuitry. Use Value: Limits clamped voltage to 53.9 V while sustaining 11.1 A surge - preserving signal integrity and preventing latch-up in 3.3 V/5 V interface ICs. | Use Scenario: Safeguarding microcontroller VCC rails and power management IC inputs against battery line transients during cold-crank or alternator load dump. IC Role / Device Role / Timing Role: Parallel-connected TVS across input capacitor to shunt energy away from downstream regulators and logic devices. Use Value: 600 W peak power rating handles ISO 7637-2 Pulse 5a (110 V, 50 ms) with minimal voltage overshoot due to low dynamic impedance. |
| ADAS Camera Module ESD Hardening | Industrial Motor Drive Feedback Protection |
Use Scenario: Shielding high-speed MIPI CSI-2 data lanes and power rails in automotive camera modules exposed to ESD during assembly and field service. IC Role / Device Role / Timing Role: Low-capacitance TVS (CJ < 100 pF at VWM) placed adjacent to image sensor and serializer ICs. Use Value: 30 kV IEC 61000-4-2 contact discharge rating prevents latch-up or gate oxide damage without degrading signal rise time. | Use Scenario: Protecting Hall-effect position feedback signals and encoder supply lines in BLDC motor drives subject to commutation noise and back-EMF spikes. IC Role / Device Role / Timing Role: TVS mounted at motor controller PCB edge to suppress common-mode transients induced by fast-switching IGBTs/MOSFETs. Use Value: 185 °C max junction temperature allows mounting near heatsinks or power stages without thermal derating penalties. |
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-HF | DO-214AC package; unidirectional; 36 V VWM; 58.1 V VC @ 10.3 A; 400 W PPPM | Requires polarity-aware layout; lower power rating; not AEC-Q101 qualified | Use where cost-sensitive industrial designs accept manual inspection and lower surge margin |
| SMCJ36CA | DO-214AB package; bidirectional; 36 V VWM; 58.1 V VC @ 10.3 A; 1500 W PPPM | Larger footprint (7.11 mm × 6.22 mm); higher clamping voltage; not optimized for AOI | Select when higher surge endurance is required and board space permits larger discrete TVS |

FAQ
What is the breakdown voltage tolerance for T6N39CAHM3/H?
The T6N39CAHM3/H has a breakdown voltage tolerance of ±5 %, with minimum, typical, and maximum values of 37.1 V, 39.0 V, and 41.0 V respectively at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margin design in automotive systems where rail voltages vary under load conditions.
Is T6N39CAHM3/H compatible with lead-free reflow processes?
Yes, the T6N39CAHM3/H is fully compatible with lead-free reflow processes, meeting JEDEC J-STD-020 MSL Level 1 with a maximum peak temperature of 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards, and the HM3 suffix confirms halogen-free, RoHS-compliant construction suitable for modern automotive manufacturing lines.
Does T6N39CAHM3/H require a heatsink for 600 W surge handling?
No, the T6N39CAHM3/H does not require an external heatsink for single-event 600 W surge handling (10/1000 μs waveform), as its thermal resistance junction-to-mount (RθJM) is only 5–6.5 °C/W. The device relies on PCB copper area for transient heat dissipation, and its 185 °C maximum junction temperature allows safe operation under short-duration surges without thermal runaway.
How does the DFN3820A package of T6N39CAHM3/H support automated optical inspection?
The DFN3820A package of T6N39CAHM3/H features side-wettable flanks - exposed metal on the vertical edges of the terminals - enabling reliable solder joint inspection via AOI systems. This eliminates the need for X-ray inspection of bottom-terminated components and improves first-pass yield in high-volume automotive PCB assembly, especially for fine-pitch, low-profile layouts where traditional pad inspection is insufficient.
What is the maximum reverse leakage current of T6N39CAHM3/H at elevated temperature?
The maximum reverse leakage current of T6N39CAHM3/H is 1.0 μA at VWM = 33.3 V and TJ = 150 °C, as specified in the Vishay datasheet. This low leakage ensures minimal power loss and signal distortion in always-on automotive modules such as body control units and telematics systems operating continuously at high ambient temperatures.
