Product details
Overview
SM6T10AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in SMB (DO-214AA) package, with 10 V standoff voltage (VWM), 14.5 V clamping voltage (VC) at 41 A peak pulse current, and 600 W peak pulse power rating per 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial control systems.
For engineers reviewing the SM6T10AHM3/I datasheet, SM6T10AHM3/I pinout, SM6T10AHM3/I application, or SM6T10AHM3/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 150 °C max junction temperature, low-inductance SMB package, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This TVS diode operates as a clamping device triggered by reverse-biased avalanche breakdown above its 10.2 V minimum breakdown voltage (VBR). Its 14.5 V clamping voltage limits transient energy delivered to downstream circuitry during 10/1000 μs surges up to 41 A.
Designed for automated SMT placement, it features glass-passivated junction, MSL Level 1 moisture sensitivity, and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. The cathode band denotes polarity; no marking on bidirectional variants.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same VWM (10 V), higher VC (16.7 V), lower PPPM (400 W), SMA package (larger footprint) | Less effective clamping margin for 12 V systems; unsuitable where board space is constrained | Select when cost sensitivity outweighs clamping performance and layout allows SMA footprint |
| SMCJ10A | Same VWM (10 V), identical VC (14.5 V), higher PPPM (1500 W), SMC package (3.5× larger area) | Over-specified for 600 W needs; adds unnecessary PCB area and thermal mass | Choose only if system-level surge testing exceeds 600 W or requires extended lifetime under repetitive stress |
Compared with SMAJ10A and SMCJ10A, SM6T10AHM3/I delivers optimal balance of clamping voltage, surge robustness, and compact SMB packaging-enabling high-density automotive PCB layouts while maintaining AEC-Q101 qualification and halogen-free compliance.

FAQ
What is the clamping voltage of SM6T10AHM3/I and how is it measured?
The SM6T10AHM3/I has a maximum clamping voltage (VC) of 14.5 V, measured at 41 A peak pulse current using a 10/1000 μs double-exponential waveform per IEC 61000-4-5. This value ensures protected circuits remain below critical overvoltage thresholds during surge events. The SM6T10AHM3/I achieves this clamping performance consistently across its operating temperature range.
Is SM6T10AHM3/I qualified for automotive applications?
Yes, SM6T10AHM3/I is AEC-Q101 qualified, as indicated by the HM3 suffix. It has passed stress tests including high-temperature operating life, temperature cycling, and ESD per JESD22 standards. This qualification confirms suitability for automotive powertrain, chassis, and body electronics where SM6T10AHM3/I provides transient protection in demanding thermal and electrical environments.
What does the "HM3" suffix mean in SM6T10AHM3/I?
The "HM3" suffix in SM6T10AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It specifies matte tin-plated leads, JESD201 Class 2 whisker resistance, and compliance with UL 94 V-0 flammability rating. This distinguishes SM6T10AHM3/I from commercial-grade M3 or E3 variants and confirms its readiness for automotive supply chain deployment.
Can SM6T10AHM3/I be used in bidirectional configurations?
No, SM6T10AHM3/I is unidirectional only, as confirmed by its part number structure and cathode band marking. For bidirectional operation, Vishay offers CA-suffixed variants such as SM6T10CA. Using SM6T10AHM3/I in reverse-biased AC signal paths would result in forward conduction and potential failure; correct polarity orientation is essential for SM6T10AHM3/I functionality.
What is the thermal resistance of SM6T10AHM3/I and how does it affect PCB layout?
SM6T10AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. To maintain safe junction temperatures under repeated surges, designers must adhere to this pad layout. Reducing pad size increases RθJA and risks exceeding the 150 °C maximum junction temperature, especially during high-duty-cycle transients.
