Product details
Overview
SM6T10AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor 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 and sensor signal lines in automotive ECUs against inductive switching transients.
For engineers reviewing the SM6T10AHM3_A/H datasheet, SM6T10AHM3_A/H pinout, SM6T10AHM3_A/H application, or SM6T10AHM3_A/H equivalent, key selection criteria include clamping performance under 10/1000 μs surge, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This device operates as a unidirectional TVS diode with a glass-passivated junction, optimized for low-inductance transient suppression in high-speed signal and power paths. Its breakdown voltage (VBR) is 9.5–10.5 V at 1.0 mA test current, and it maintains stable clamping up to 150 °C junction temperature.
The SM6T10AHM3_A/H uses an SMB (DO-214AA) package with matte tin-plated leads, meets JESD201 Class 2 whisker resistance, and is rated for MSL Level 1 reflow (260 °C peak). It is specifically qualified to AEC-Q101 for automotive applications, distinguishing it from commercial-grade E3/M3 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 8.55 V - Maximum reverse voltage before conduction; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 9.5–10.5 V at 1.0 mA - Ensures reliable turn-on during transients without premature leakage |
| VC (Clamping Voltage) | 14.5 V at IPPM = 41 A (10/1000 μs) - Limits protected circuit voltage during worst-case surge |
| PPPM (Peak Pulse Power) | 600 W - Sustains high-energy transients typical of automotive load-dump or inductive kick events |
| TJ max. | +150 °C - Enables operation in under-hood environments without derating in most PCB layouts |
| RθJA | 100 °C/W - Requires minimum 0.2" × 0.2" copper pads per terminal for full power rating |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
Pinout & Package
SMB (DO-214AA) surface-mount package with cathode band marking on the unidirectional SM6T10AHM3_A/H; case dimensions 4.57 mm × 3.94 mm × 2.20 mm; matte tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode-side connection point for reverse-biased protection path | Connected to protected line; conducts when transient exceeds VWM, shunting current to ground |
| Anode | Reference/ground return path | Typically tied to system ground plane; completes clamping loop with minimal inductance |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Handles automotive-level load-dump surges without degradation or failure |
| AEC-Q101 qualification (HM3 suffix) | Validated reliability for engine control units, ADAS sensors, and body electronics |
| Low clamping ratio (VC/VWM ≈ 1.71) | Minimizes overvoltage stress on downstream ICs compared to higher-ratio TVS devices |
| Halogen-free & RoHS-compliant | Meets EU ELV and automotive OEM material restrictions without compromising surge robustness |
| MSL Level 1 moisture sensitivity | Enables standard SMT reflow without baking, reducing manufacturing overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same VWM (8.55 V) and VC (14.5 V), but lower PPPM (400 W); SMB package identical; no AEC-Q101 qualification | Not approved for automotive under-hood use; suitable only for commercial-grade consumer/industrial boards | Select SMAJ10A only if AEC-Q101 is not required and surge energy remains ≤400 W |
| SMCJ10A | Higher PPPM (1500 W), same VWM/VC, but larger SMC (DO-214AB) package; footprint incompatible with SMB layout | Used where higher surge immunity is needed but board space allows larger footprint and thermal mass | Choose SMCJ10A when system-level surge testing exceeds 600 W and PCB redesign is feasible |
Compared with SMAJ10A and SMCJ10A, the SM6T10AHM3_A/H uniquely delivers AEC-Q101 qualification in the compact SMB footprint while maintaining 600 W capability-enabling drop-in replacement in automotive designs where space and reliability are co-constrained.

FAQ
What is the clamping voltage of SM6T10AHM3_A/H at its rated peak pulse current?
The SM6T10AHM3_A/H has a maximum clamping voltage (VC) of 14.5 V when subjected to a 10/1000 μs waveform peak pulse current (IPPM) of 41 A. This value is measured under standardized test conditions per JEDEC standards and ensures predictable overvoltage limiting during surge events. The SM6T10AHM3_A/H maintains this clamping performance across its full operating temperature range up to +150 °C.
Is SM6T10AHM3_A/H qualified for automotive applications?
Yes, the SM6T10AHM3_A/H is AEC-Q101 qualified, as indicated by the HM3 suffix in its part number. This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT). The SM6T10AHM3_A/H is approved for use in automotive engine control units, body electronics, and ADAS sensor modules where reliability under thermal and electrical stress is mandatory.
What does the "HM3" suffix mean in SM6T10AHM3_A/H?
The "HM3" suffix in SM6T10AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from commercial-grade versions (E3/M3) and confirms compliance with automotive material restrictions and reliability standards. The SM6T10AHM3_A/H also meets JESD201 Class 2 whisker resistance and MSL Level 1 reflow requirements, making it suitable for lead-free SMT assembly without pre-baking.
How does SM6T10AHM3_A/H compare to SM6T10A-E3 in terms of thermal performance?
The SM6T10AHM3_A/H and SM6T10A-E3 share identical thermal characteristics: both have RθJA = 100 °C/W and RθJL = 20 °C/W, and both require the same 0.2" × 0.2" copper pad layout for full 600 W rating. The difference lies in qualification-not thermal design. The SM6T10AHM3_A/H adds AEC-Q101 validation and halogen-free materials, but its thermal behavior under identical mounting conditions matches that of SM6T10A-E3.
Can SM6T10AHM3_A/H be used in bidirectional configurations?
No, SM6T10AHM3_A/H is a unidirectional TVS diode, as confirmed by its part number structure (no "CA" suffix) and datasheet specifications. Bidirectional operation requires the CA suffix (e.g., SM6T10CA). Using SM6T10AHM3_A/H in a bidirectional application would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. Always select SM6T10CA or equivalent for AC-coupled or symmetrical surge protection.
