Product details
Overview
T6N22AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor in DFN3820A package, featuring 22.0 V nominal breakdown voltage (VBR), 18.8 V stand-off voltage (VWM), 30.6 V clamping voltage at 19.6 A peak pulse current, and 600 W peak pulse power rating (10/1000 μs). It is AEC-Q101 qualified and rated for 185 °C junction temperature, designed for automotive sensor signal-line protection against inductive switching transients.
For engineers reviewing the T6N22AHM3/I datasheet, T6N22AHM3/I pinout, T6N22AHM3/I application, or T6N22AHM3/I equivalent, this page delivers verified electrical parameters, thermal performance data, AOI-compatible packaging details, and automotive-grade reliability context - all specific to the T6N22AHM3/I variant with HM3 halogen-free, RoHS-compliant, whisker-tested construction.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and low-leakage operation. Its unidirectional configuration provides precise reverse-biased clamping with 1.0 mA test current and ≤1.0 μA reverse leakage at VWM (TA = 25 °C).
The DFN3820A package enables automated placement and supports Automatic Optical Inspection via side-wettable flanks. Thermal resistance is specified as RθJA ≤ 175 °C/W (JEDEC 51-2A) and RθJM ≤ 6.5 °C/W (JEDEC 51-14), enabling robust thermal management in compact automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nominal) | 22.0 V - Ensures reliable triggering above system operating voltage while maintaining margin against false clamping. |
| VWM | 18.8 V - Maximum continuous reverse working voltage compatible with 12 V automotive supply rails. |
| VC @ IPPM | 30.6 V - Clamping voltage at 19.6 A limits protected IC stress during 600 W transient events. |
| IPPM | 19.6 A - Peak surge current capacity for 10/1000 μs waveform ensures survivability under ISO 7637-2 Pulse 1/2a/3a conditions. |

Applications
| Automotive Sensor Signal Protection | Engine Control Unit (ECU) Input Protection |
|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and analog sensor signals (e.g., MAP, TPS) from load-dump and inductive kickback in 12 V systems. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground to clamp transients before they reach sensitive input stages. Use Value: Limits clamped voltage to 30.6 V at 19.6 A, preventing damage to 3.3 V/5 V microcontrollers and ADC front-ends while maintaining signal integrity. | Use Scenario: Safeguarding microcontroller GPIOs and analog inputs in engine control units exposed to alternator load dump (ISO 7637-2 Pulse 5a). IC Role / Device Role / Timing Role: Primary overvoltage suppression device on power-supply rail and signal lines interfacing with solenoids or ignition coils. Use Value: Withstands 600 W pulses and operates up to +185 °C, ensuring protection remains effective even during extended high-temperature engine operation. |
| ADAS Camera Module ESD Protection | Body Control Module (BCM) Communication Lines |
Use Scenario: Shielding high-speed image sensor interfaces (e.g., MIPI CSI-2) from ESD events during vehicle assembly or service. IC Role / Device Role / Timing Role: Low-capacitance TVS placed directly at connector entry point to shunt ESD energy before it couples into signal traces. Use Value: ±30 kV IEC 61000-4-2 immunity and minimal parasitic capacitance preserve signal rise/fall times required for >1 Gbps video links. | Use Scenario: Protecting LIN bus lines and door module switches from electrostatic discharge and relay-induced transients in interior lighting and window control systems. IC Role / Device Role / Timing Role: Standoff-rated TVS (VWM = 18.8 V) placed across LIN differential pair to absorb common-mode surges without disrupting 12 V bias. Use Value: Maintains functional safety by preventing latch-up or permanent failure in LIN transceivers during repeated surge exposure over 15-year vehicle life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A-E3/57T | DO-214AC package (larger footprint, higher RθJA ≈ 40 °C/W), same VBR/VC specs but lower IPPM (17.3 A), no AEC-Q101 qualification. | Not suitable for space-constrained or high-reliability automotive modules; limited to industrial/commercial PCBs with thermal relief. | Select only if DFN footprint is not required and AEC-Q101 compliance is unnecessary. |
| TPSMD22A | DO-214AB package, higher clamping voltage (33.2 V), same 600 W rating, AEC-Q101 qualified, but larger size and no side-wettable flanks. | Compatible for retrofit in legacy designs using SMB/SMA footprints, but lacks AOI support and has reduced board-area efficiency. | Choose when upgrading from older SMA/SMB TVS without redesigning land pattern or inspection process. |
Compared with SMAJ22A-E3/57T and TPSMD22A, the T6N22AHM3/I offers superior board-area efficiency, automated optical inspectability, and guaranteed automotive qualification - making it the preferred choice for new-generation compact, high-reliability automotive electronics where thermal performance and process compatibility are critical.

FAQ
What is the breakdown voltage tolerance for T6N22AHM3/I?
The T6N22AHM3/I has a ±5 % breakdown voltage tolerance, confirmed by its "A" suffix in the part number. At 25 °C and 1.0 mA test current, VBR is specified as 20.9 V (min), 22.0 V (nom), and 23.1 V (max). This tight tolerance ensures predictable clamping behavior across production lots and temperature ranges, critical for protecting precision analog inputs in automotive systems.
Is T6N22AHM3/I compatible with lead-free reflow processes?
Yes, T6N22AHM3/I is fully compatible with lead-free reflow soldering, meeting JEDEC J-STD-020 MSL Level 1 with a maximum peak temperature of 260 °C. Its matte tin-plated terminals comply with JESD 22-B102, and the HM3 suffix confirms halogen-free, RoHS-compliant construction - making it suitable for standard Pb-free assembly lines without special handling.
Does T6N22AHM3/I require a thermal pad connection to PCB ground?
Yes, the exposed anode thermal pad of T6N22AHM3/I must be soldered to a PCB copper pour or ground plane to achieve specified thermal performance. Without this connection, RθJM degrades significantly, risking thermal runaway under repeated 600 W surges. The datasheet specifies RθJM ≤ 6.5 °C/W only when the pad is properly mounted and thermally coupled.
How does T6N22AHM3/I perform at elevated temperatures?
T6N22AHM3/I maintains full functionality up to +185 °C junction temperature, with VBR exhibiting a positive temperature coefficient of +0.084 %/°C. At 150 °C, reverse leakage remains ≤1.0 μA at VWM, and clamping performance is derated per Figure 2 in the datasheet - enabling reliable operation in under-hood ECUs and transmission control units.
What is the meaning of the "HM3" and "I" suffixes in T6N22AHM3/I?
The "HM3" suffix denotes halogen-free, RoHS-compliant, AEC-Q101 qualified construction with JESD201 Class 2 whisker resistance; "I" indicates 13-inch tape-and-reel packaging with 14,000 units per reel. This distinguishes T6N22AHM3/I from the "H" variant (7-inch reel, 3,500 units), both sharing identical electrical and thermal specifications but differing only in packaging format and quantity.
