Product details
Overview
SMCJ13AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 13 V standoff voltage (VWM), 21.5 V maximum clamping voltage at 69.8 A peak pulse current (10/1000 µs), and 1500 W peak pulse power rating - deployed in automotive ECUs, industrial sensor interfaces, and power supply input stages.
For engineers reviewing the SMCJ13AHM3/H datasheet, SMCJ13AHM3/H pinout, SMCJ13AHM3/H application, or SMCJ13AHM3/H equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance (RθJA = 75 °C/W), AEC-Q101 qualification status, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 14.4–15.9 V breakdown range (VBR at 1 mA). Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response (<1 ns), while the SMC package supports automated placement and meets MSL Level 1 reflow (260 °C peak).
Designed for transient suppression per IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT), it delivers low incremental surge resistance and maintains clamping integrity across -55 °C to +150 °C operating junction temperature, with derating above 25 °C per Fig. 2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR min/max | 14.4 V / 15.9 V at 1 mA - Ensures reliable turn-on margin above VWM with tight tolerance |
| VC @ IPPM | 21.5 V at 69.8 A (10/1000 µs) - Limits protected circuit voltage during worst-case surge |
| PPPM | 1500 W - Sustains high-energy transients without failure under standardized waveform |
| IFSM | 200 A (8.3 ms half-sine) - Withstands repetitive inrush or fault currents in power rail protection |
| TJ max | +150 °C - Enables operation in under-hood automotive and high-temperature industrial environments |
| RθJA | 75 °C/W - Defines thermal rise from junction to ambient on standard 8 mm × 8 mm copper pads |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller power inputs in engine control units against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between VIN and GND, absorbing energy before it reaches downstream regulators. Use Value: Clamps to ≤21.5 V during 1500 W surges, preserving LDO and MCU functionality without derating or overdesign. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA transmitter outputs) from ESD and cable discharge events in factory automation systems. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted at connector entry point, shunting transients before signal conditioning circuitry. Use Value: Sub-1 ns response and <1.0 µA leakage at 13 V ensure minimal signal distortion and no DC loading on precision current loops. |
| DC Power Supply Input Stage | Telecom Line Card Surge Protection |
Use Scenario: Front-end protection of AC/DC adapter secondary-side 12–24 V outputs exposed to field wiring faults and lightning-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on DC bus, coordinated with upstream fuses and downstream TVS arrays. Use Value: 1500 W rating and 200 A surge capability enable single-device coverage of IEC 61000-4-5 Level 3 (1 kV/2 Ω) requirements. | Use Scenario: Secondary-side protection of Ethernet PHY power rails and bias supplies in carrier-grade access equipment. IC Role / Device Role / Timing Role: Standoff-rated TVS on isolated DC-DC converter outputs feeding sensitive SerDes and clock buffers. Use Value: 13 V VWM aligns with common 12 V logic rails; AEC-Q101 qualification adds reliability assurance beyond commercial-grade alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/57T | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W) | Suitable for space-constrained consumer PCBs where surge energy is limited | Select when board area is critical and peak surge energy remains below 400 W |
| SMCJ13AHE3_A/H | Same electrical specs, but RoHS-compliant commercial grade (E3) without halogen-free or AEC-Q101 qualification | Applicable in non-automotive industrial designs with less stringent reliability requirements | Choose for cost-sensitive applications where AEC-Q101 and halogen-free are not mandated |
Compared with SMCJ13AHM3/H, SMAJ13A-E3/57T offers smaller size but reduced surge handling and thermal performance, while SMCJ13AHE3_A/H matches core specs but lacks automotive qualification and halogen-free materials - making SMCJ13AHM3/H the optimal choice for AEC-Q101-compliant, high-reliability deployments.

FAQ
What is the clamping voltage of SMCJ13AHM3/H at its rated peak pulse current?
The SMCJ13AHM3/H has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPPM) of 69.8 A, measured using the standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on the protected circuit during surge events and is confirmed in the Electrical Characteristics table on page 2 of the Vishay datasheet 88394.
Is SMCJ13AHM3/H qualified for automotive applications?
Yes, SMCJ13AHM3/H is AEC-Q101 qualified, as indicated by the "HM3" suffix and explicitly noted in the Mechanical Data section of the Vishay datasheet. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - confirming suitability for under-hood and chassis-mounted automotive electronics.
What does the "HM3" suffix mean in SMCJ13AHM3/H?
The "HM3" suffix in SMCJ13AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering information table, HM3 parts use matte tin-plated leads, meet JESD 201 Class 2 whisker resistance, and are rated for MSL Level 1 reflow - distinguishing them from commercial-grade E3 variants and bidirectional CA versions.
How does SMCJ13AHM3/H differ from SMCJ13AHE3_A/H?
SMCJ13AHM3/H and SMCJ13AHE3_A/H share identical electrical parameters (VWM, VBR, VC, PPPM) and SMC package, but differ in qualification and material content: HM3 is halogen-free and AEC-Q101 qualified, whereas HE3 is RoHS-compliant only (no halogen-free statement or automotive qualification). Both use the same "H" tape-and-reel packaging code.
What is the thermal resistance of SMCJ13AHM3/H, and how does it affect layout design?
The SMCJ13AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes standard PCB layout - reducing pad area or omitting thermal vias increases RθJA, potentially limiting sustained power dissipation and requiring derating above 25 °C per Figure 2 in the datasheet.
