Product details
Overview
SMB10J16AHM3_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 16 V stand-off voltage (VWM), 1000 W peak pulse power (10/1000 µs), clamping voltage of 26.0 V at 38.5 A peak pulse current, and AEC-Q101 qualification for automotive electronics.
For engineers reviewing the SMB10J16AHM3_A/H datasheet, SMB10J16AHM3_A/H pinout, SMB10J16AHM3_A/H application, or SMB10J16AHM3_A/H equivalent, this device is selected for robust overvoltage protection in automotive ECUs, industrial sensor interfaces, and 12 V/24 V board-level power inputs where low clamping voltage, fast response (<1 ns), and halogen-free RoHS compliance are required.
Technical Context
This TVS diode operates as a clamping-type protector using an avalanche breakdown junction. Its glass-passivated silicon chip delivers sub-nanosecond response to transients and maintains stable VBR (17.8–19.7 V) at 1 mA test current, with <1.0 µA reverse leakage at 16 V stand-off.
Thermally, it supports operation from –55 °C to +150 °C junction temperature, with RθJA = 72 °C/W (on 5.0 mm × 5.0 mm copper pads) and RθJL = 20 °C/W. The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification per stress test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 12 V automotive systems. |
| VBR min/max | 17.8 V / 19.7 V at 1 mA - Confirmed breakdown threshold range ensures reliable triggering without premature conduction. |
| VC @ IPPM | 26.0 V at 38.5 A - Clamping voltage under 10/1000 µs surge; limits downstream IC stress to safe levels during load dump. |
| PPPM | 1000 W - Peak pulse power rating; sustains 1000 W transient energy without failure when mounted per recommended pad layout. |
| IFSM | 100 A - Non-repetitive forward surge current (8.3 ms half-sine); supports high-current inductive switching events. |
| Junction Temp | –55 °C to +150 °C - Enables deployment in engine bay, powertrain, and industrial control environments. |
| Qualification | AEC-Q101 qualified - Validated for automotive reliability including HTOL, TC, UHAST, and ESD testing. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / surge return path | Connected to protected line (e.g., battery rail); conducts during positive transients when cathode is biased higher. |
| Cathode | Clamping reference / surge sink | Connected to ground or lower-potential reference; avalanche conduction diverts surge current to ground when VAK exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free & RoHS-compliant | HM3 suffix confirms full compliance with JEDEC J-STD-201 Class 2 whisker resistance and environmental regulations. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, high-temperature operating life, and unbiased HAST. |
| Low incremental surge resistance | Enables tight clamping (26.0 V at 38.5 A), minimizing voltage overshoot on sensitive 12 V microcontroller power supplies. |
| Glass-passivated junction | Ensures long-term stability of VBR and leakage performance across thermal and humidity stress conditions. |
| MSL Level 1 (260 °C) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns or baking requirements. |
Applications
| Automotive Body Control Module (BCM) | Industrial CAN Transceiver Protection |
|---|---|
|
Use Scenario: Protecting 12 V supply input of BCM against ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 5a (load dump). IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between battery rail and input filter capacitor. Use Value: Limits transient voltage to ≤26.0 V during 1000 W surges, preventing damage to LDOs and MCU power domains. |
Use Scenario: Safeguarding CAN_H/CAN_L lines in factory automation nodes exposed to motor drive EMI and relay switching noise. IC Role / Device Role / Timing Role: Bidirectional TVS (e.g., SMB8J16CA variant) used across differential pair; SMB10J16AHM3_A/H applied on single-ended VCC rail. Use Value: Sub-ns response clamps fast-rising transients before they couple into CAN PHY, preserving bus integrity. |
| 12 V DC-DC Converter Input Stage | Automotive Sensor Signal Conditioning |
|
Use Scenario: Input surge protection for buck converter feeding ADAS camera module power rail. IC Role / Device Role / Timing Role: Primary TVS on 12 V input, upstream of input capacitor and EMI filter. Use Value: Withstands 100 A surge (8.3 ms) and 1000 W pulses while maintaining <1 µA leakage at 16 V, avoiding quiescent current penalty. |
Use Scenario: Protecting analog outputs (e.g., 0–5 V throttle position sensor) from wiring harness coupling and electrostatic discharge. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS on signal line to ground, with cathode tied to signal and anode to GND. Use Value: Clamps ESD events to <26.0 V without distorting small-signal accuracy due to minimal leakage and stable VBR. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMB10J16AHE3_B/H | Same electrical specs and SMB package; RoHS-compliant but not halogen-free (E3 vs HM3). | Lacks halogen-free certification; suitable for commercial/industrial, not automotive AEC-Q101 programs requiring HM3. | Select SMB10J16AHM3_A/H when halogen-free compliance and AEC-Q101 are mandatory for Tier 1 automotive sourcing. |
| SMBJ16A-E3/52 | Same VWM/VC, but rated for 600 W PPPM (vs 1000 W); different thermal derating curve and RθJA. | Lower surge handling capacity; insufficient for ISO 7637-2 Pulse 5a load dump in 12 V systems. | Choose SMB10J16AHM3_A/H where full 1000 W capability and AEC-Q101 are required; SMBJ16A-E3/52 fits lower-energy signal-line roles. |
Compared with SMB10J16AHE3_B/H and SMBJ16A-E3/52, SMB10J16AHM3_A/H uniquely combines 1000 W surge rating, AEC-Q101 qualification, and halogen-free construction-enabling first-tier automotive deployment without design compromise or secondary qualification.

FAQ
What is the clamping voltage of SMB10J16AHM3_A/H at its rated peak pulse current?
The SMB10J16AHM3_A/H has a maximum clamping voltage (VC) of 26.0 V at 38.5 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured and guaranteed per Vishay Document Number 88422, ensuring predictable overvoltage limiting during surge events on 12 V systems.
Is SMB10J16AHM3_A/H suitable for automotive applications?
Yes, SMB10J16AHM3_A/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction validated for automotive use. It meets stress test requirements for temperature cycling, high-temperature operating life, and unbiased HAST-making SMB10J16AHM3_A/H appropriate for engine control units, body modules, and ADAS power rails.
What does the "HM3" suffix mean in SMB10J16AHM3_A/H?
The "HM3" suffix in SMB10J16AHM3_A/H denotes halogen-free, RoHS-compliant packaging with JESD 201 Class 2 whisker resistance and AEC-Q101 qualification. It distinguishes this variant from E3 (RoHS only) and HE3 (AEC-Q101 + RoHS but not halogen-free), confirming full compliance for stringent automotive Tier 1 supply chains.
How does SMB10J16AHM3_A/H differ from SMBJ16A in surge handling capability?
SMB10J16AHM3_A/H is rated for 1000 W peak pulse power (10/1000 µs), whereas SMBJ16A is rated for 600 W. This 67% higher surge capacity enables SMB10J16AHM3_A/H to withstand ISO 7637-2 Pulse 5a load dump events in 12 V automotive systems-where SMBJ16A would risk thermal runaway or parametric shift.
What is the mounting pad layout recommendation for SMB10J16AHM3_A/H?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad area per terminal for SMB10J16AHM3_A/H to achieve rated thermal performance (RθJA = 72 °C/W). Deviation reduces surge current capability and accelerates junction temperature rise; the pad layout is critical to sustaining 1000 W pulses without degradation.
