Product details
Overview
SMB10J36AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails 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 maximum clamping voltage (VC) at 17.2 A peak pulse current (IPPM), and 1000 W peak pulse power (10/1000 µs waveform), qualified to AEC-Q101 for automotive use.
For engineers reviewing the SMB10J36AHM3_A/H datasheet, SMB10J36AHM3_A/H pinout, SMB10J36AHM3_A/H application, or SMB10J36AHM3_A/H equivalent, this part delivers validated automotive-grade transient suppression with low incremental surge resistance, fast response time, and MSL Level 1 moisture sensitivity - critical for ECU power input, sensor interface, and infotainment supply rail protection.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents <1.0 µA reverse leakage at 36 V; during transients exceeding VBR, it avalanches to clamp voltage ≤58.1 V while conducting up to 17.2 A (10/1000 µs). Its glass-passivated junction ensures stable breakdown and low capacitance (<100 pF at 0 V), supporting high-speed signal line protection without signal integrity degradation.
Thermally, it sustains operation from –55 °C to +150 °C junction temperature, with RθJA = 72 °C/W (on 0.2" × 0.2" copper pads) and RθJL = 20 °C/W, enabling reliable performance in engine bay and ADAS modules. The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification per stress test conditions including HTRB, HTGB, and temperature cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before significant leakage; sets safe margin below system nominal voltage (e.g., 36 V for 24 V automotive systems). |
| VBR (min/max) | 40.0 V / 44.2 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on across production lot and temperature. |
| VC @ IPPM | 58.1 V at 17.2 A - Clamped voltage during 10/1000 µs surge; defines protected IC's maximum stress level during ISO 7637-2 Pulse 1/2/5a events. |
| PPPM | 1000 W - Peak pulse power handling (10/1000 µs); supports robust protection against load dump and inductive switching surges. |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); enables survival of high-current battery connection transients. |
| TJ max | +150 °C - Maximum junction temperature; allows direct placement near heat sources in automotive ECUs without derating. |
| AEC-Q101 | Qualified - Validated for automotive reliability: HTGB, HTRB, TCT, UHAST, and mechanical shock per AEC standard. |

Applications
| Engine Control Unit (ECU) Power Input | Automotive Camera Sensor Interface |
|---|---|
Use Scenario: Protects 24 V supply rail of diesel/gasoline ECU against ISO 7637-2 Pulse 5a (load dump) and Pulse 1 (inductive switch-off). IC Role / Device Role / Timing Role: Shunt TVS diode placed upstream of DC/DC converter input; clamps transients within 1 ns response time to limit voltage seen by downstream regulators. Use Value: Maintains VC ≤ 58.1 V during 17.2 A surge, preventing overvoltage damage to 40 V-rated input capacitors and controller ICs. |
Use Scenario: Shields MIPI CSI-2 signal pair and 12 V bias rail of surround-view camera module from ESD and cable discharge events. IC Role / Device Role / Timing Role: Unidirectional TVS on power rail; bidirectional variants used on differential pairs - this part protects only the DC supply path. Use Value: With <1.0 µA leakage at 36 V, avoids loading 12 V bias rail; clamps ESD surges to <60 V, preserving image sensor analog front-end integrity. |
| Infotainment System USB Power Port | ADAS Radar Module 5 V Supply |
Use Scenario: Guards 5 V USB VBUS line in head unit against hot-plug transients, load dump coupling, and conducted noise from vehicle battery. IC Role / Device Role / Timing Role: Standoff-rated TVS (VWM = 36 V) used on 5 V rail - selected for margin above 5.5 V max; clamps only during severe overvoltage. Use Value: High VWM/VBR ratio prevents false triggering; 1000 W rating handles sustained surges without thermal runaway. |
Use Scenario: Safeguards 5 V LDO output powering radar SoC against coupled transients from 12 V input stage during ignition events. IC Role / Device Role / Timing Role: Secondary-stage TVS on regulated 5 V rail; complements primary protection on 12 V input to provide cascaded defense. Use Value: Low clamping voltage (58.1 V) irrelevant here - instead, its low leakage and stable VBR ensure no drift-induced misclamping on sensitive 5 V domain. |
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/H | Same VWM/VBR/VC specs, but E3 suffix (RoHS-compliant commercial grade, not AEC-Q101 qualified). | Lacks automotive qualification; suitable for industrial or consumer power supplies where AEC-Q101 is not mandated. | Select SMBJ36AHE3_A/H only if automotive qualification is unnecessary and cost is prioritized over qualification traceability. |
| SMB10J36AHM3_A/L | Identical electrical specs and AEC-Q101 qualification; differs only in tape-and-reel packaging (3200 pcs/reel vs. 750 pcs/reel for _A/H). | No functional difference; choice depends solely on production volume and SMT line feeder compatibility. | Choose SMB10J36AHM3_A/L for high-volume automated assembly requiring larger reels; otherwise retain _A/H for prototyping or low-volume builds. |
Compared with SMBJ36AHE3_A/H, SMB10J36AHM3_A/H adds AEC-Q101 validation for automotive deployment; compared with SMB10J36AHM3_A/L, it offers smaller reel quantity for flexibility in design-in and pilot runs - both alternatives preserve identical clamping behavior and thermal performance.

FAQ
What is the clamping voltage of SMB10J36AHM3_A/H at its rated peak pulse current?
The SMB10J36AHM3_A/H has a maximum clamping voltage (VC) of 58.1 V at 17.2 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 09-Jan-2024, ensuring predictable overvoltage limiting for downstream 40 V-rated components in automotive power systems.
Is SMB10J36AHM3_A/H suitable for bidirectional signal line protection?
No - SMB10J36AHM3_A/H is a unidirectional TVS diode, intended for DC power rail protection where transients occur only in one polarity. For bidirectional signal lines (e.g., CAN, LIN, or USB D+/D−), a bidirectional variant like SMB8J36CAHM3_A/H must be used; using SMB10J36AHM3_A/H on such lines would fail to suppress negative-going transients.
Does SMB10J36AHM3_A/H meet automotive qualification standards?
Yes - the HM3 suffix explicitly denotes halogen-free, RoHS-compliant construction and full AEC-Q101 qualification. This includes testing for high-temperature reverse bias (HTGB), high-temperature operating life (HTOL), temperature cycling, and unbiased highly accelerated stress test (UHAST), making SMB10J36AHM3_A/H approved for use in automotive powertrain, body, and ADAS modules.
What is the thermal resistance of SMB10J36AHM3_A/H, and how does it affect PCB layout?
SMB10J36AHM3_A/H 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. To achieve this rating, the PCB must implement minimum pad dimensions per Vishay's recommended layout - undersized pads increase RθJA, risking thermal runaway during repeated surges.
How does the leakage current of SMB10J36AHM3_A/H compare to other 36 V TVS diodes?
At its 36 V stand-off voltage (VWM), SMB10J36AHM3_A/H exhibits ≤1.0 µA maximum reverse leakage current at 25 °C - consistent with Vishay's SMB10J family and tighter than many competing 36 V TVS diodes (e.g., some SMBJ variants specify ≤5 µA). This low leakage minimizes standby power loss in always-on automotive modules like telematics or gateway ECUs.
