Product details
Overview
SMCJ13CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with 21.5 V maximum clamping voltage at 69.8 A peak pulse current and 13 V stand-off voltage. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMCJ13CAHM3_A/H datasheet, SMCJ13CAHM3_A/H pinout, SMCJ13CAHM3_A/H application, or SMCJ13CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge rating, low incremental surge resistance, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This TVS diode operates as a voltage-clamping protection device across bidirectional signal or power rails, responding within picoseconds to transient overvoltages induced by inductive switching or ESD events. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at 13 V), while the SMC package supports automated placement and meets MSL Level 1 reflow requirements.
The device delivers symmetrical clamping in both polarities, with a 14.4–15.9 V breakdown range at 1.0 mA test current and a temperature coefficient of +0.084 %/°C. Thermal resistance is 75 °C/W junction-to-ambient on standard 8.0 mm × 8.0 mm copper pads, enabling reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
SMCJ13CAHM3_A/H uses the SMC (DO-214AB) package: a two-terminal, non-polarized surface-mount case with no marking for bidirectional devices. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional terminal pair | No polarity marking; either terminal serves as anode or cathode depending on transient polarity |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 1500 W peak pulse rating | Supports robust immunity against IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS subsystems |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes voltage overshoot during transients, reducing stress on downstream silicon |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking preconditioning |
Applications
| Automotive Power Distribution | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protection of 12 V battery-fed ECUs against load dump and alternator transients. IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC-DC converters and microcontrollers. Use Value: Limits transient voltage to ≤21.5 V during 69.8 A surges, preventing latch-up or gate oxide damage in protected ICs. | Use Scenario: Shielding analog outputs of pressure/temperature sensors in PLC I/O modules. IC Role / Device Role / Timing Role: Bidirectional shunt protector on differential or single-ended sensor outputs referenced to chassis ground. Use Value: Maintains signal integrity under ±1 kV EFT bursts by clamping both positive and negative excursions symmetrically. |
| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Surge suppression on RS-485 bus lines exposed to lightning-induced coupling in outdoor base stations. IC Role / Device Role / Timing Role: Secondary-level protection aligned with common-mode chokes and primary GDTs. Use Value: Absorbs residual 10/1000 μs surges after front-end filtering, ensuring <100 ns response prevents data corruption. | Use Scenario: Protecting half-bridge gate drivers in washing machine motor inverters from inductive kickback. IC Role / Device Role / Timing Role: Rail-to-rail clamp across high-side and low-side driver supply rails. Use Value: Prevents driver IC destruction during MOSFET turn-off by clamping VDD–VSS spikes to ≤21.5 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA-E3/61 | Lower PPPM (400 W), SMA package (smaller thermal mass), same VWM/VBR range | Not suitable for 1500 W surge environments; limited to lower-energy interfaces like USB or GPIO | Select when board space is constrained and surge threat level is ≤IEC 61000-4-5 Level 2 |
| SMCJ13CAHE3_A/H | Same electrical specs and package, but RoHS-compliant commercial grade (E3) instead of halogen-free (HM3) | Lacks halogen-free certification; not acceptable for automotive OEMs requiring full material declarations | Choose for cost-sensitive industrial designs where halogen-free compliance is not mandated |
Compared with SMCJ13CAHM3_A/H, SMAJ13CA-E3/61 offers reduced surge capability in a smaller footprint, while SMCJ13CAHE3_A/H provides identical protection performance without halogen-free assurance-making the HM3 variant essential for automotive Tier 1 supply chains.

FAQ
What does the "CA" suffix indicate in SMCJ13CAHM3_A/H?
The "CA" suffix denotes a bidirectional configuration: SMCJ13CAHM3_A/H clamps voltage transients equally in both polarities, making it suitable for AC-coupled or floating circuits where polarity reversal may occur. Unlike unidirectional variants (e.g., SMCJ13A), it has no cathode band marking and exhibits matched breakdown characteristics in forward and reverse directions per the Vishay datasheet.
Is SMCJ13CAHM3_A/H qualified for automotive use?
Yes, SMCJ13CAHM3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure (HM3 suffix) and documentation. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and unbiased highly accelerated stress testing-validating its use in automotive powertrain, body electronics, and ADAS modules where reliability under thermal and electrical stress is mandatory.
What is the maximum clamping voltage of SMCJ13CAHM3_A/H under surge conditions?
The maximum clamping voltage (VC) of SMCJ13CAHM3_A/H is 21.5 V at 69.8 A peak pulse current using the standardized 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and represents the highest voltage imposed on the protected circuit during worst-case transient events, directly limiting stress on downstream components such as microcontrollers or gate drivers.
How does the HM3 suffix differ from E3 or HE3 in SMCJ13CAHM3_A/H?
The HM3 suffix in SMCJ13CAHM3_A/H indicates halogen-free, RoHS-compliant, and AEC-Q101 qualified construction-distinct from E3 (RoHS-compliant commercial grade only) and HE3 (RoHS-compliant + AEC-Q101, but not halogen-free). HM3 meets strict automotive material declarations and environmental standards required by major OEMs, including JESD201 Class 2 whisker resistance.
Can SMCJ13CAHM3_A/H be used in place of a unidirectional TVS like SMCJ13A?
No-SMCJ13CAHM3_A/H is strictly bidirectional and lacks polarity marking, so it cannot replace unidirectional SMCJ13A in DC-biased circuits where cathode/anode orientation matters. Substitution would risk improper clamping or failure to conduct during negative transients. Use SMCJ13CAHM3_A/H only where symmetrical protection is required, such as AC signal paths or floating supplies.
