Product details
Overview
SM6T10AHM3_B/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), 10.5 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 ICs against inductive switching transients in automotive power electronics.
For engineers reviewing the SM6T10AHM3_B/H datasheet, SM6T10AHM3_B/H pinout, SM6T10AHM3_B/H application, or SM6T10AHM3_B/H 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 device operates as a unidirectional TVS diode with avalanche breakdown behavior, designed to clamp transient overvoltages before they damage downstream circuitry. Its glass-passivated junction ensures stable VBR (9.5–10.5 V) and low leakage (<10 μA at 8.55 V).
The SM6T10AHM3_B/H is rated for 600 W peak pulse power under standardized 10/1000 μs waveform conditions, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W, enabling reliable operation up to 150 °C junction temperature without forced cooling on recommended 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.55 V - maximum reverse operating voltage before significant conduction begins; defines safe signal line bias range |
| VBR min/max | 9.50 V / 10.5 V - breakdown occurs within this band at 1.0 mA test current; ensures predictable clamping onset |
| VC @ IPPM | 14.5 V at 41.0 A - clamped voltage during 600 W transient; limits stress on protected ICs |
| PPPM | 600 W - peak pulse power handling per 10/1000 μs waveform; meets IEC 61000-4-5 Level 4 surge immunity |
| TJ max | +150 °C - maximum junction temperature; supports under-hood automotive environments |
| Package | SMB (DO-214AA) - surface-mount package with 2.20 mm height and 5.59 mm length; compatible with automated SMT placement |
| Polarity | Unidirectional - cathode marked by band; blocks forward current until breakdown, conducts reverse surge to ground |
Pinout & Package
SMB (DO-214AA) package: molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL level 1, 260 °C reflow peak. Cathode band denotes terminal 1; anode is unmarked terminal 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected circuit node; conducts surge current to ground when voltage exceeds VWM |
| Anode (unmarked end) | Reference/ground return | Typically tied to system ground plane; completes low-inductance path for clamping current |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22-A114 |
| Halogen-free & RoHS-compliant | Meets JEDEC J-STD-208 and EU RoHS Directive 2011/65/EU; no brominated flame retardants |
| 600 W peak pulse power | Withstands 41 A surge at 14.5 V clamping-sufficient for ISO 7637-2 Pulse 1/2a/5a protection in 12 V systems |
| Low inductance SMB package | Minimizes voltage overshoot during fast transients (e.g., <100 ns rise time); critical for protecting high-speed logic |
| Glass passivated junction | Ensures stable VBR over lifetime and temperature; eliminates risk of junction degradation under repeated surges |
Applications

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 SMB package, 10 V VWM, but only 400 W PPPM (vs. 600 W); RθJA = 110 °C/W | Lacks AEC-Q101 qualification; not approved for automotive under-hood use | Select SMAJ10A only for cost-sensitive industrial applications where 400 W surge margin suffices |
| SMCJ10A | Higher 1500 W PPPM, larger SMC (DO-214AB) package; VWM = 8.55 V, VC = 14.5 V | Requires PCB layout change due to 7.11 mm body length vs. SMB's 5.59 mm; higher thermal mass | Choose SMCJ10A when system-level surge testing exceeds IEC 61000-4-5 Level 4 or requires extended lifetime under repetitive surges |
Compared with SMAJ10A and SMCJ10A, the SM6T10AHM3_B/H delivers optimal balance of automotive qualification, 600 W surge capacity, and compact SMB footprint-enabling drop-in replacement in space-constrained AEC-Q101 designs without thermal derating or layout revision.

FAQ
What is the clamping voltage of the SM6T10AHM3_B/H under a 600 W transient?
The SM6T10AHM3_B/H clamps to a maximum of 14.5 V when subjected to its rated 600 W peak pulse power with a 10/1000 μs waveform. This value is measured at 41.0 A peak pulse current (IPPM) and ensures downstream components experience controlled overvoltage stress during surge events.
Is the SM6T10AHM3_B/H qualified for automotive applications?
Yes, the SM6T10AHM3_B/H carries the HM3 suffix, confirming it is halogen-free, RoHS-compliant, and AEC-Q101 qualified. It has undergone stress testing including temperature cycling, high-temperature reverse bias, and ESD per JESD22 standards for automotive under-hood deployment.
What does the "_B/H" suffix indicate in SM6T10AHM3_B/H?
The "_B/H" suffix in SM6T10AHM3_B/H specifies packaging configuration: "B" denotes tape-and-reel format per EIA-481, and "H" indicates a 7″ diameter reel containing 750 units. This matches Vishay's preferred ordering code SM6T10AHM3_B/H for automated SMT assembly.
How does the SMB package of SM6T10AHM3_B/H compare to SMA or SMC in surge handling?
The SMB (DO-214AA) package of SM6T10AHM3_B/H offers lower thermal resistance (RθJL = 20 °C/W) than SMA but higher than SMC. Its 600 W rating is optimized for the SMB footprint-exceeding SMAJ-series (400 W) while fitting tighter layouts than SMCJ-series (1500 W, DO-214AB).
Can SM6T10AHM3_B/H be used in bidirectional configurations?
No, SM6T10AHM3_B/H is strictly unidirectional, as confirmed by its "A" suffix and cathode band marking. For bidirectional operation, Vishay specifies CA-suffixed variants like SM6T10CA; using SM6T10AHM3_B/H in reverse-biased AC paths would result in forward conduction and failure.
