Product details
Overview
T6N22CAHM3/H 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/H datasheet, T6N22CAHM3/H pinout, T6N22CAHM3/H application, or T6N22CAHM3/H equivalent, this AEC-Q101 qualified TVS diode delivers verified clamping performance (30.6 V at 19.6 A), high-temperature operation up to 185 °C, and side-wettable flanks for AOI-compatible automated assembly in safety-critical automotive electronics.
Technical Context
This device implements a passivated anisotropic rectifier structure optimized for low-leakage bidirectional clamping with 1.0 µA max reverse leakage at VWM and 6.0 µA at 150 °C. Its DFN3820A footprint enables compact placement on high-density PCBs while maintaining thermal resistance RθJA ≤ 175 °C/W under JEDEC 51-2A conditions.
The T6N22CAHM3/H operates as a single-channel, unidirectional-clamp-free transient suppressor - its bidirectional symmetry eliminates polarity dependency during layout. It meets IEC 61000-4-2 ±30 kV contact/air discharge and supports surge current derating above 25 °C per Figure 2, enabling robust design across extended automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 20.9 / 22.0 / 23.1 V - ensures reliable conduction onset within ±5 % tolerance at 1 mA test current |
| VWM | 18.8 V - maximum continuous working voltage before significant leakage begins |
| VC @ IPPM | 30.6 V - clamping voltage at 19.6 A peak pulse current, limiting downstream voltage stress |

Use Scenario: Protecting LIN/CAN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector or IC input pins to limit transient excursions below IC absolute maximum ratings. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V interface ICs by clamping surges to ≤30.6 V while sustaining 19.6 A peak current. |
Use Scenario: Safeguarding 12 V/24 V automotive power rails feeding microcontrollers, gate drivers, and communication modules against battery reverse connection and alternator load dump. IC Role / Device Role / Timing Role: Primary transient suppression element placed upstream of DC-DC converters and LDO regulators to absorb energy before it reaches sensitive downstream circuitry.

| ADAS Camera Interface | Motor Control Gate Protection |
|
Use Scenario: Shielding high-speed video signal lines (e.g., FPD-Link III, GMSL) in rear-view and surround-view camera modules from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS placed adjacent to serializer/deserializer ICs to minimize signal integrity impact while providing ±30 kV ESD immunity. Use Value: Maintains signal fidelity with minimal parasitic capacitance (typ. <100 pF at 0 V), validated per IEC 61000-4-2 compliance testing. |
Use Scenario: Protecting N-channel MOSFET gates in BLDC motor drivers from Miller-induced voltage spikes during high-di/dt switching transitions. IC Role / Device Role / Timing Role: Fast-response clamp between gate and source to suppress overshoot exceeding VGS(max), preventing gate oxide breakdown. Use Value: Achieves sub-nanosecond response time and clamps gate-source voltage to ≤30.6 V, preserving MOSFET reliability under repetitive PWM stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22CA | DO-214AC (SMA) package; 22 V VBR; 400 W PPPM; higher RθJA (~190 °C/W) | Larger footprint; unsuitable for ultra-compact automotive modules requiring DFN packaging | Select when board space allows larger package and cost sensitivity outweighs AOI compatibility needs |
| SMCJ22CA | DO-214AB (SMC) package; 22 V VBR; 1500 W PPPM; 3× larger footprint than DFN3820A | Higher power rating but incompatible with automated optical inspection due to lack of side-wettable flanks | Choose only for industrial applications where 1500 W surge margin is mandatory and AEC-Q101 is not required |
Compared with SMAJ22CA and SMCJ22CA, the T6N22CAHM3/H provides superior board-level integration density, AEC-Q101 validation, and AOI-ready manufacturability - making it the preferred choice for next-generation automotive electronics where space, reliability, and production yield are jointly constrained.

FAQ
What is the exact breakdown voltage tolerance for T6N22CAHM3/H?
The T6N22CAHM3/H has a ±5 % breakdown voltage tolerance, confirmed by its "CA" suffix per Vishay's ordering nomenclature. At 1 mA test current, its VBR range is 20.9 V (min) to 23.1 V (max), with 22.0 V nominal - verified in Table 1 of Document Number 98489.
Is T6N22CAHM3/H compatible with lead-free reflow profiles?
Yes, T6N22CAHM3/H is rated for lead-free reflow with a maximum peak temperature of 260 °C per J-STD-020 MSL Level 1, and its matte tin-plated terminals meet J-STD-002 solderability requirements. The HM3 suffix confirms halogen-free, RoHS-compliant, and Pb-free construction.
Does T6N22CAHM3/H require a heatsink for 600 W pulse handling?
No external heatsink is required for single-pulse 600 W (10/1000 µs) events. The DFN3820A package achieves RθJM ≤ 6.5 °C/W to the PCB mount pad, allowing effective heat dissipation into the copper plane. Continuous power dissipation remains limited by RθJA ≤ 175 °C/W under standard JEDEC conditions.
How does T6N22CAHM3/H perform at elevated ambient temperatures?
T6N22CAHM3/H maintains full functionality up to +185 °C junction temperature. Derating curves in Figure 2 show that at 125 °C ambient, its peak pulse power remains ≥400 W - sufficient for under-hood automotive applications where sustained high-temperature operation is required.
Can T6N22CAHM3/H be used in bidirectional data line protection like CAN or LIN?
Yes, T6N22CAHM3/H is explicitly designed for bidirectional signal line protection. Its symmetrical clamping behavior, low leakage (<1 µA at 18.8 V), and ±30 kV ESD rating make it suitable for CAN FD, LIN, and other automotive serial buses - provided system-level clamping voltage margins align with transceiver VI/O limits.
