Product details
Overview
SMCJ10AHM3_A/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 10 V standoff voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V clamping voltage (VC) at 88.2 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMCJ10AHM3_A/H datasheet, SMCJ10AHM3_A/H pinout, SMCJ10AHM3_A/H application, or SMCJ10AHM3_A/H equivalent, key selection criteria include its AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, low incremental surge resistance, fast response time, and suitability for automotive power rail and sensor interface protection where high-energy transients must be clamped without device failure.
Technical Context
The SMCJ10AHM3_A/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its specified breakdown range. Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress. Thermal resistance is characterized at RθJA = 75 °C/W (on recommended 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W, supporting sustained operation up to TJ = 150 °C.
It meets J-STD-020 MSL Level 1 moisture sensitivity and JESD201 Class 2 whisker resistance requirements. The matte tin-plated leads are solderable per J-STD-002 and JESD22-B102, and polarity is marked by a cathode band - critical for correct orientation in DC-biased protection circuits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10AHE3_A/H | Lower PPPM (400 W), smaller SMA package (DO-214AC), same VWM/VBR range, also AEC-Q101 and halogen-free. | Not suitable for ISO 7637-2 Pulse 5a (load dump); limited to lower-energy threats like ESD and EFT. | Select when board space is constrained and surge energy is ≤400 W - e.g., secondary protection or low-power sensor nodes. |
| SMCJ10AHE3_A/H | Identical electrical specs and SMC package, but uses standard RoHS-compliant (E3) termination instead of halogen-free (HM3). | No functional difference in protection performance; differs only in material compliance and whisker resistance class (both meet JESD201 Class 2). | Choose when halogen-free requirement is not mandated - e.g., commercial or industrial applications outside automotive OEM supply chains. |
Compared with SMCJ10AHM3_A/H, SMAJ10AHE3_A/H offers space savings at the cost of 73 % lower surge power handling, while SMCJ10AHE3_A/H delivers identical protection performance with standard RoHS compliance - making HM3 the preferred choice strictly for halogen-free automotive designs.

FAQ
What is the clamping voltage of SMCJ10AHM3_A/H at its rated peak pulse current?
The SMCJ10AHM3_A/H has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated 10/1000 µs peak pulse current of 88.2 A. This value is measured under standardized test conditions per JEDEC standards and ensures downstream components see no more than 17.0 V during surge events. The SMCJ10AHM3_A/H maintains this clamping performance across its qualified temperature range and after repeated surge exposure, provided layout follows Vishay's recommended pad dimensions.
Is SMCJ10AHM3_A/H suitable for automotive applications?
Yes, SMCJ10AHM3_A/H is explicitly qualified to AEC-Q101 for automotive use, confirmed by the "HM3" suffix denoting halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. It is rated for junction temperatures up to +150 °C and validated for thermal cycling, high-temperature reverse bias, and surge endurance - making it appropriate for engine bay, chassis, and ADAS subsystems. The SMCJ10AHM3_A/H meets ISO 7637-2 Pulse 1, 2a, and 5a requirements when properly mounted.
How does the HM3 suffix differ from the HE3 suffix in SMCJ10A variants?
The HM3 suffix indicates halogen-free, RoHS-compliant, and AEC-Q101-qualified construction, whereas HE3 denotes RoHS-compliant and AEC-Q101-qualified but not halogen-free. Both meet JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1, but HM3 complies with JEDEC JS709E for halogen content (<900 ppm Br, <900 ppm Cl, total ≤1500 ppm). For SMCJ10AHM3_A/H, this distinction matters in automotive Tier 1 supply chains requiring full green material declarations.
What is the standoff voltage (VWM) of SMCJ10AHM3_A/H, and why is it important?
The standoff voltage (VWM) of SMCJ10AHM3_A/H is 10 V - the maximum DC or continuous reverse voltage the device can withstand without entering avalanche conduction. This parameter ensures the SMCJ10AHM3_A/H remains non-conductive during normal operation of a 12 V system, minimizing leakage current (<5 µA) and power loss. Selecting VWM ≥10 % above nominal rail voltage prevents nuisance triggering while preserving headroom for ripple and tolerance.
Can SMCJ10AHM3_A/H be used in bidirectional protection circuits?
No, SMCJ10AHM3_A/H is a unidirectional TVS diode, indicated by the "A" (not "CA") suffix and cathode band marking. It conducts only when the cathode is positive relative to the anode. For bidirectional protection - such as AC lines or differential buses - a part with "CA" suffix (e.g., SMCJ10CA) must be used. Using SMCJ10AHM3_A/H in bidirectional configurations risks permanent failure due to forward conduction during negative half-cycles.
