Product details
Overview
SM6T10CAHM3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 10 V standoff voltage (VWM), 12.8 V minimum breakdown voltage (VBR), 600 W peak pulse power (10/1000 μs), and 150 °C max junction temperature - used to protect automotive sensor signal lines and MOSFET gates against ESD and inductive switching transients.
For engineers reviewing the SM6T10CAHM3_A/H datasheet, SM6T10CAHM3_A/H pinout, SM6T10CAHM3_A/H application, or SM6T10CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, low clamping voltage (VC = 18.6 V at IPPM), and SMB package compatibility with automated SMT assembly.
Technical Context
This TVS diode operates symmetrically in both directions due to its CA suffix designation, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM).
The device delivers 600 W surge handling per 10/1000 μs waveform under standard mounting conditions (0.2" × 0.2" copper pads), with clamping voltage tightly specified at 18.6 V (max) and thermal resistance RθJA = 100 °C/W - supporting reliable operation in compact automotive and industrial PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min) | 12.8 V - guaranteed breakdown starts no lower than this, ensuring margin over VWM |
| VC (max) | 18.6 V - clamps transients to ≤18.6 V at 41.0 A peak pulse current (10/1000 μs) |
| PPPM | 600 W - peak surge power handling capability under standardized transient waveform |
| TJ max | +150 °C - enables use in under-hood automotive environments and high-temperature industrial zones |
| Package | SMB (DO-214AA) - surface-mount outline with 2.20 mm height and 3.94 mm length, optimized for pick-and-place |
| AEC-Q101 | Qualified - certified for automotive-grade reliability per stress test requirements |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance. Bidirectional construction means no polarity marking on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; reverse-bias reference for one clamping direction | Terminal that conducts when voltage at cathode exceeds anode by ≥VBR - identical behavior in both directions |
| Cathode | Current exit terminal in forward bias; reverse-bias reference for opposite clamping direction | Terminal that conducts when voltage at anode exceeds cathode by ≥VBR - symmetrical clamping enables AC protection |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of differential pairs, AC lines, or ungrounded signal paths without polarity constraints |
| 600 W peak pulse power | Withstands high-energy transients such as ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 surges |
| AEC-Q101 qualified | Validated for automotive applications including engine control units, ADAS sensors, and infotainment interfaces |
| Halogen-free & RoHS-compliant | Meets environmental compliance requirements for global OEM supply chains and end-of-life recycling |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during suppression, reducing risk of downstream IC damage |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across signal line and ground to shunt transients before reaching sensitive input stages. Use Value: Prevents latch-up or permanent damage to microcontrollers and ADC front-ends while maintaining signal integrity during 10/1000 μs surges up to 41 A. | Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Transient suppressor connected between field-side input and isolated logic side to absorb inductive kick energy. Use Value: Enables robust operation in harsh factory environments where repetitive 600 W surges occur without derating or thermal shutdown. |
| Consumer Power Adapter Interface | Telecom Line Card Surge Protection |
Use Scenario: Clamping induced transients on USB-C CC lines and auxiliary power rails in wall adapters and charging docks. IC Role / Device Role / Timing Role: Fast-response TVS placed adjacent to connector to limit voltage spikes before entering USB PD controller ICs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V), but lower PPPM (400 W); SMB package identical; not AEC-Q101 qualified | Limited to commercial-grade consumer/industrial use; unsuitable for automotive under-hood deployment | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom |
| 1.5KE10CA | Higher power (1500 W), axial DO-201 package; larger footprint and manual assembly required | Used where board space allows and higher surge margin is mandatory (e.g., AC mains input stages) | Choose only if PCB layout permits through-hole mounting and system-level surge testing exceeds 600 W |
Compared with SMAJ10CA and 1.5KE10CA, SM6T10CAHM3_A/H uniquely combines AEC-Q101 qualification, 600 W capability, and SMB surface-mount compatibility - making it optimal for space-constrained, automotive-grade signal line protection where reliability and manufacturability are co-prioritized.

FAQ
What does the "CA" suffix indicate in SM6T10CAHM3_A/H?
The "CA" suffix in SM6T10CAHM3_A/H denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities - ideal for protecting AC-coupled signals, differential buses like CAN or RS-485, and ungrounded sensor interfaces without requiring polarity-aware placement.
Is SM6T10CAHM3_A/H suitable for automotive applications?
Yes, SM6T10CAHM3_A/H is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials - meeting automotive reliability standards for under-hood and cabin electronics, including engine control units, ADAS camera modules, and body control modules where transient immunity is critical.
What is the maximum clamping voltage of SM6T10CAHM3_A/H at rated peak pulse current?
The maximum clamping voltage (VC) of SM6T10CAHM3_A/H is 18.6 V when subjected to its rated peak pulse current of 41.0 A under the standard 10/1000 μs waveform - verified per Vishay Document Number 88385, page 2, Electrical Characteristics table.
How does the SMB package of SM6T10CAHM3_A/H compare to SMA or SMC alternatives?
The SMB (DO-214AA) package of SM6T10CAHM3_A/H offers a 3.94 mm × 2.20 mm footprint - smaller than SMC but larger than SMA - balancing surge capability (600 W) with board space efficiency and automated placement compatibility, unlike SMA's lower power rating or SMC's larger thermal mass.
Does SM6T10CAHM3_A/H require external heat sinking for continuous operation?
No, SM6T10CAHM3_A/H is rated for 5.0 W power dissipation on an infinite heatsink at TA = 50 °C and relies on PCB copper pad thermal conduction (0.2" × 0.2" per terminal) - no external heatsink needed in typical surge-protection roles where duty cycle remains low and ambient stays below 125 °C.
