Product details
Overview
SM6T10CAHM3_A/I 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), and 600 W peak pulse power (10/1000 μs). It clamps transients to ≤17.0 V at 35.3 A IPPM and is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive use.
For engineers reviewing the SM6T10CAHM3_A/I datasheet, SM6T10CAHM3_A/I pinout, SM6T10CAHM3_A/I application, or SM6T10CAHM3_A/I equivalent, key selection criteria include bidirectional clamping capability, low clamping voltage under 10/1000 μs surge, AEC-Q101 qualification status, SMB package thermal performance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering consistent clamping behavior during positive and negative transients without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while low inductance supports fast response to ESD and lightning-induced surges.
Designed for surface-mount applications, the device meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, and its RθJA of 100 °C/W (typ.) and RθJL of 20 °C/W (typ.) enable reliable thermal management in compact layouts without heatsinking.
Key Specifications

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs and body control modules against ISO 7637-2 pulse 1, 2a, and 5a transients. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector entry point to shunt surge energy before it reaches LDOs and MCU I/O. Use Value: Limits transient voltage to ≤17.0 V, preventing latch-up or gate oxide damage in 12 V–rated silicon while maintaining AEC-Q101 compliance. | Use Scenario: Safeguarding analog front-end inputs of pressure, temperature, or position sensors exposed to relay-coil flyback and motor noise. IC Role / Device Role / Timing Role: Low-leakage (≤1.0 μA) TVS placed adjacent to sensor IC pins to suppress sub-μs ESD and inductive spikes without loading signal integrity. Use Value: Maintains signal fidelity due to low capacitance and preserves accuracy by avoiding DC offset from leakage current. |
| Telecom Data Line Surge Suppression | Consumer USB Port ESD Protection |
Use Scenario: Shielding RS-485/RS-422 differential pairs in base station backhaul equipment from lightning-induced surges. IC Role / Device Role / Timing Role: Paired bidirectional TVS devices on each line, leveraging symmetrical clamping to preserve differential mode immunity. Use Value: Delivers matched clamping thresholds (±17.0 V) across both lines, minimizing common-mode distortion during 600 W surge events. | Use Scenario: Hardening USB 2.0 D+/D− lines in smart home hubs against IEC 61000-4-2 ±8 kV contact discharge. IC Role / Device Role / Timing Role: Fast-response TVS integrated into USB connector flex circuit, placed before USB PHY to prevent ESD-induced reset or data corruption. Use Value: Sub-1 ns response time and low clamping voltage ensure PHY logic states remain intact during ESD events. |
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), lower PPPM (400 W), SMA package (larger RθJA = 140 °C/W) | Limited to lower-energy transients; less suitable for automotive load-dump where 600 W margin is required | Select when cost sensitivity outweighs peak power requirement and board space allows larger SMA footprint |
| SMCJ10CA | Same VWM (10 V), higher PPPM (1500 W), SMC package (RθJA = 50 °C/W), larger footprint (7.11 mm × 6.22 mm) | Better thermal performance and surge margin but occupies >2× PCB area vs. SMB | Choose for industrial motor drives needing higher single-pulse robustness and improved thermal derating |
Compared with SMAJ10CA and SMCJ10CA, SM6T10CAHM3_A/I delivers optimal balance of AEC-Q101 qualification, 600 W surge rating, and compact SMB footprint-making it preferred for space-constrained automotive and portable industrial designs where qualification and size are critical.

FAQ
What does the "HM3" suffix indicate in SM6T10CAHM3_A/I?
The HM3 suffix in SM6T10CAHM3_A/I denotes halogen-free, RoHS-compliant construction with full AEC-Q101 qualification. It confirms compliance with automotive reliability standards including temperature cycling, highly accelerated life testing (HALT), and electrostatic discharge (ESD) robustness-critical for under-hood and infotainment applications.
Is SM6T10CAHM3_A/I unidirectional or bidirectional?
SM6T10CAHM3_A/I is a bidirectional TVS diode, as confirmed by the "CA" suffix and absence of polarity marking. It provides symmetrical clamping for both positive and negative transients, making it ideal for protecting AC-coupled lines, differential buses like RS-485, and floating sensor inputs without polarity concerns.
What is the maximum clamping voltage of SM6T10CAHM3_A/I at rated peak pulse current?
The maximum clamping voltage (VC) of SM6T10CAHM3_A/I is 17.0 V at 35.3 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and is measured per JEDEC standards.
Can SM6T10CAHM3_A/I be used in place of a unidirectional TVS like SM6T10A?
No-SM6T10CAHM3_A/I is bidirectional and lacks polarity marking, whereas SM6T10A is unidirectional with cathode band identification. Substituting them requires verifying circuit topology: SM6T10CAHM3_A/I suits AC or floating nodes; SM6T10A is required for DC rails where forward conduction must be blocked in one direction.
What PCB pad layout is recommended for optimal thermal performance of SM6T10CAHM3_A/I?
Vishay specifies mounting SM6T10CAHM3_A/I on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power and thermal resistance (RθJA = 100 °C/W). Smaller pads reduce surge capability and increase junction temperature-especially critical in automotive under-hood environments.
