Product details
Overview
SMB10J36AHM3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on power and signal lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 1 mA, 58.1 V clamping voltage (VC) at 17.2 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the SMB10J36AHM3/I datasheet, SMB10J36AHM3/I pinout, SMB10J36AHM3/I application, or SMB10J36AHM3/I equivalent, key selection criteria include AEC-Q101 qualification, halogen-free RoHS compliance (HM3 suffix), unidirectional polarity with cathode band marking, and thermal resistance (RθJA = 72 °C/W) under standard PCB pad layout.
Technical Context
This device operates as a clamping-type overvoltage protector, leveraging an avalanche breakdown mechanism to limit transient voltages before they damage downstream ICs or MOSFETs. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 µA at VWM), while MSL Level 1 rating supports lead-free reflow up to 260 °C peak.
The SMB10J36AHM3/I delivers fast response time (<1 ns), low incremental surge resistance, and robust surge handling per IEC 61000-4-5 (line-to-ground surges). It is rated for continuous operation from –55 °C to +150 °C junction temperature, with derating applied above TA = 25 °C per Fig. 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping initiates; defines safe DC/AC working margin. |
| VBR min/max | 40.0 V / 44.2 V at IT = 1 mA - tight breakdown window ensures predictable turn-on across production lots. |
| VC @ IPPM | 58.1 V at 17.2 A (10/1000 µs) - clamping voltage limits stress on protected circuitry during surge events. |
| PPPM | 1000 W - peak pulse power capability determines survivability against high-energy transients like load dump. |
| ID @ VWM | <1.0 µA - ultra-low leakage preserves battery life and avoids false triggering in low-power sensor nodes. |
| TJ max | +150 °C - enables use in under-hood automotive environments and thermally constrained industrial enclosures. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by color band on one end; polarity critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / surge return path | Connected to lower-potential side (e.g., GND or return rail); completes clamping loop during positive transients. |
| Cathode | Reverse-biased terminal / clamping node | Connected to protected line (e.g., 36 V rail); conducts avalanche current when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS power domains. |
| Halogen-free & RoHS-compliant (HM3) | Meets environmental compliance requirements for global OEMs without compromising surge performance. |
| Glass passivated junction | Ensures long-term stability of VBR and low parametric drift under thermal cycling and humidity stress. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow profiles without preconditioning or special handling. |
| Low RθJA (72 °C/W) | Enables effective heat dissipation on minimal 0.2" × 0.2" copper pads, reducing thermal runaway risk. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

Use Scenario: Safeguarding analog front-end inputs of pressure/temperature sensors exposed to ESD and inductive switching noise. IC Role / Device Role / Timing Role: Unidirectional TVS connected from signal line to ground, absorbing ±8 kV contact ESD (IEC 61000-4-2) and 40 A surge currents. Use Value: Maintains sub-1 µA leakage at 36 V, avoiding signal offset errors in precision 24-bit ADC measurement paths. |
| Telecom DC Power Input Protection | Motor Drive Gate Driver Protection |
|

IC Role / Device Role / Timing Role: Reverse-connected unidirectional TVS referenced to system ground, clamping negative-going transients on the return path. Use Value: Withstands 1000 W pulses without degradation, enabling single-device protection instead of stacked Zener arrays. |
Use Scenario: Shielding high-side N-channel MOSFET gate drivers from Miller-induced voltage spikes during fast switching. IC Role / Device Role / Timing Role: TVS placed between gate and source to clamp dv/dt-induced overshoot exceeding VGS(max) rating. Use Value: Fast <1 ns response prevents unintended turn-on; 58.1 V clamping protects gate oxide rated for 20 V max. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMB10J36AHE3/I | Same electrical specs, but RoHS-compliant commercial grade (E3) - no halogen-free certification. | Lacks AEC-Q101 qualification and halogen-free status; suitable for non-automotive industrial use only. | Select SMB10J36AHM3/I when automotive qualification or halogen-free compliance is mandatory. |
| SMAJ36A | Lower PPPM (400 W), higher VC (68.7 V at 5.8 A), SMA package (smaller footprint, higher RθJA). | Insufficient for 1000 W load dump; limited to lower-energy surges in space-constrained consumer designs. | Choose SMB10J36AHM3/I where full 1000 W surge immunity and automotive reliability are required. |
Compared with SMB10J36AHE3/I and SMAJ36A, the SMB10J36AHM3/I uniquely combines AEC-Q101 qualification, halogen-free construction, and 1000 W surge rating in SMB package - making it the only drop-in solution for Tier-1 automotive power rail protection requiring both regulatory compliance and high-energy clamping.

FAQ
What is the clamping voltage of SMB10J36AHM3/I at its rated peak pulse current?
The SMB10J36AHM3/I has a maximum clamping voltage (VC) of 58.1 V at 17.2 A peak pulse current (IPPM), measured with a 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in the "Unidirectional" table on page 2 of Vishay document 88422. The SMB10J36AHM3/I maintains this clamping performance across its qualified operating temperature range.
Is SMB10J36AHM3/I suitable for automotive applications?
Yes, SMB10J36AHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction - explicitly intended for automotive use. It meets stress test requirements including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22-A114. The SMB10J36AHM3/I is commonly deployed in engine control modules, body electronics, and ADAS power domains where reliability under thermal and electrical stress is critical.
What does the "HM3" suffix mean in SMB10J36AHM3/I?
The "HM3" suffix in SMB10J36AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering nomenclature, HM3 indicates compliance with JEDEC J-STD-20 moisture sensitivity level 1, lead-free reflow compatibility (260 °C peak), and material restrictions including bromine and chlorine content below 900 ppm. This distinguishes SMB10J36AHM3/I from E3 (RoHS-only) and HE3 (AEC-Q101, non-halogen-free) variants.
How is polarity identified on SMB10J36AHM3/I?
SMB10J36AHM3/I is a unidirectional TVS diode with polarity marked by a cathode band - a visible color stripe located near one end of the SMB (DO-214AA) package. During PCB layout, the banded end must be connected to the line being protected (e.g., 36 V rail), while the opposite (anode) terminal connects to ground or return. No marking appears on bidirectional variants, but SMB10J36AHM3/I is strictly unidirectional per its part number and datasheet classification.
What is the thermal resistance of SMB10J36AHM3/I, and how does it affect layout?
The SMB10J36AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Thermal Characteristics table. This value assumes minimum recommended pad layout; reducing pad area increases RθJA and risks thermal runaway during repeated surges. Layout must follow Vishay's mounting recommendations to ensure SMB10J36AHM3/I sustains full 1000 W pulse rating without exceeding TJ(max) = +150 °C.
