Product details
Overview
SMB10J36AHM3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection in automotive and industrial power rails. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 1000 W peak pulse power (10/1000 µs), 17.2 A peak pulse current (IPPM), and clamps to ≤58.1 V at rated surge - protecting downstream MOSFETs and ICs against load dump and inductive switching transients.
For engineers reviewing the SMB10J36AHM3/H datasheet, SMB10J36AHM3/H pinout, SMB10J36AHM3/H application, or SMB10J36AHM3/H equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant HM3 suffix, unidirectional polarity with cathode band marking, and suitability for 12 V/24 V automotive power line protection where low clamping voltage and fast response (<1 ns) are critical.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, triggering when reverse voltage exceeds VBR (40.0–44.2 V) and diverting surge current away from sensitive circuitry. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
Designed per ANSI/IEEE C62.35 standards, it delivers 1000 W peak pulse power with a 10/1000 µs waveform, exhibits ≤1.0 µA reverse leakage at 36 V, and maintains thermal resistance of 72 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads - enabling robust operation up to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before conduction begins; sets safe margin below system nominal voltage (e.g., 24 V rail). |
| VBR (min/max) | 40.0 V / 44.2 V - verified breakdown range at 1 mA test current; defines precise turn-on threshold for reliable clamping onset. |
| VC @ IPPM | ≤58.1 V - clamping voltage at 17.2 A peak pulse current; determines maximum voltage seen by protected device during surge. |
| PPPM | 1000 W - peak pulse power handling (10/1000 µs); supports high-energy transients like ISO 7637-2 Pulse 5a (load dump). |
| ID @ VWM | ≤1.0 µA - ultra-low reverse leakage at 36 V; minimizes standby power loss and avoids false triggering in low-current circuits. |
| TJ max. | +150 °C - maximum junction temperature rating; enables use in under-hood automotive environments without derating. |
| Package | SMB (DO-214AA) - surface-mount, low-profile package with matte tin-plated leads; compatible with automated SMT assembly and J-STD-002 solderability. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36AHE3/A | Same VWM (36 V), VBR (40–44.2 V), and PPPM (1000 W), but uses E3 suffix (RoHS-compliant commercial grade, not AEC-Q101 qualified). | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated. | Select SMBJ36AHE3/A only if automotive qualification is unnecessary and cost sensitivity outweighs long-term reliability validation. |
| SMB10J36AHE3/H | Identical electrical specs and SMB package, but HE3 suffix indicates RoHS-compliant AEC-Q101 qualification without halogen-free constraint. | Acceptable for automotive use but does not meet halogen-free material requirements (e.g., VW 80101 or GMW3172). | Choose SMB10J36AHE3/H when halogen-free content is not required but AEC-Q101 compliance remains mandatory. |
Compared with SMB10J36AHM3/H, SMBJ36AHE3/A omits automotive qualification and halogen-free status, while SMB10J36AHE3/H retains AEC-Q101 but lacks halogen-free certification - making SMB10J36AHM3/H the sole option meeting both requirements simultaneously for Tier 1 automotive BOMs.

The SMB10J36AHM3/H clamps to a maximum of 58.1 V at its rated peak pulse current of 17.2 A (10/1000 µs waveform). This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring compatibility with downstream components rated for ≤60 V absolute maximum.
Is SMB10J36AHM3/H suitable for automotive applications?
Yes, SMB10J36AHM3/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction - meeting stringent automotive reliability and environmental requirements. It is explicitly intended for use in engine control units, body electronics, and ADAS systems where load dump and inductive switching transients must be suppressed without failure.
What does the "HM3" suffix mean in SMB10J36AHM3/H?
The "HM3" suffix in SMB10J36AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from E3 (RoHS commercial), M3 (halogen-free commercial), and HE3 (RoHS + AEC-Q101, non-halogen-free) versions - confirming compliance with automotive material standards such as VW 80101 and GMW3172.
How does SMB10J36AHM3/H differ from SMBJ36AHE3/A?
SMB10J36AHM3/H and SMBJ36AHE3/A share identical electrical parameters (VWM = 36 V, VBR = 40–44.2 V, PPPM = 1000 W) and SMB package, but SMB10J36AHM3/H adds AEC-Q101 qualification and halogen-free materials via the HM3 suffix, whereas SMBJ36AHE3/A is commercial-grade only (E3) - limiting its use to non-automotive applications.
What is the maximum operating junction temperature for SMB10J36AHM3/H?
The maximum operating junction temperature for SMB10J36AHM3/H is +150 °C, as specified in the Vishay datasheet. This rating allows reliable operation in under-hood automotive environments and high-temperature industrial settings, provided PCB layout provides adequate copper pad area (0.2" × 0.2") for thermal dissipation.
