Product details
Overview
SMB10J15AHM3_B/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 15 V stand-off voltage (VWM), 16.7–18.5 V breakdown voltage (VBR) at 1 mA, 24.4 V clamping voltage (VC) at 41 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMB10J15AHM3_B/H datasheet, SMB10J15AHM3_B/H pinout, SMB10J15AHM3_B/H application, or SMB10J15AHM3_B/H equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity with cathode band marking, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that transitions from high-impedance to low-impedance state during overvoltage transients, limiting voltage across protected circuitry. Its glass-passivated junction ensures stable breakdown behavior, while MSL Level 1 rating and 260 °C lead-free reflow compatibility support robust manufacturing.
The SMB10J15AHM3_B/H delivers 1000 W peak pulse power handling under standardized 10/1000 µs waveform conditions, with thermal resistance of 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation up to 150 °C junction temperature in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 15 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin for 12 V systems. |
| VBR (Breakdown Voltage) | 16.7–18.5 V at 1 mA - precise threshold where avalanche conduction begins; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 24.4 V at IPPM = 41 A - maximum voltage seen by protected IC during 1000 W surge; critical for MOSFET gate or MCU I/O survivability. |
| PPPM (Peak Pulse Power) | 1000 W (10/1000 µs) - energy-handling capacity for automotive load-dump or inductive switching events. |
| IFSM (Surge Current) | 100 A (8.3 ms half-sine) - withstands repetitive power-rail surges without degradation; supports long-term reliability in engine control units. |
| TJ max | 150 °C - enables deployment in under-hood automotive environments and industrial enclosures without derating. |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. Cathode indicated by color band; polarity critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or return path; forms clamping loop with cathode to limit voltage rise on protected line. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 12 V rail); color band identifies this terminal for correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including temperature cycling, HTRB, and ESD stress - required for ECUs and ADAS modules. |
| Halogen-free & RoHS-compliant (HM3 suffix) | Meets global environmental compliance mandates without compromising surge performance or thermal stability. |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free assembly without moisture-related popcorning or delamination risks. |
| Glass-passivated junction | Ensures consistent VBR tolerance and long-term stability under repeated surge stress and thermal cycling. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast transients, improving protection margin for sensitive 3.3 V or 5 V logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15AHE3_A/H | Same VWM (15 V), VBR (16.7–18.5 V), VC (24.4 V), but rated for 600 W PPPM (vs. 1000 W); non-AEC-Q101 commercial grade. | Limited to non-automotive industrial or consumer use where lower surge energy suffices. | Select when cost sensitivity outweighs automotive qualification and 1000 W headroom. |
| 1.5SMC15A | Same electrical specs but in larger SMC (DO-214AB) package; RθJA = 40 °C/W vs. 72 °C/W; higher thermal mass but less board space efficiency. | Better thermal performance in high-ambient environments, but incompatible with dense SMB footprints. | Choose only if layout allows SMC pad size and thermal management prioritizes junction cooling over footprint density. |
Compared with SMBJ15AHE3_A/H and 1.5SMC15A, SMB10J15AHM3_B/H uniquely combines AEC-Q101 qualification, 1000 W surge rating, and SMB footprint - making it the only option qualified for automotive front-end power protection without package or reliability trade-offs.

FAQ
What is the clamping voltage of SMB10J15AHM3_B/H at its rated peak pulse current?
The SMB10J15AHM3_B/H has a maximum clamping voltage (VC) of 24.4 V at 41 A peak pulse current (IPPM), measured under standardized 10/1000 µs waveform conditions. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in Vishay's Document Number 88422, page 2, unidirectional table. The SMB10J15AHM3_B/H maintains this clamping performance across its qualified operating temperature range.
Is SMB10J15AHM3_B/H suitable for automotive applications?
Yes, SMB10J15AHM3_B/H is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet (Document Number 88422, page 1). The HM3 suffix denotes halogen-free, RoHS-compliant construction with automotive-grade reliability testing - including temperature cycling, highly accelerated life testing (HALT), and ESD validation. This makes SMB10J15AHM3_B/H appropriate for engine control units, ADAS sensors, and body electronics where qualification is mandatory.
What does the "HM3_B/H" suffix mean in SMB10J15AHM3_B/H?
The "HM3" suffix indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification; "B/H" specifies packaging: 7″ diameter tape-and-reel with 750 units per reel (H = reel size code per Vishay ordering guide). This matches the preferred package code "H" listed in the Ordering Information table on page 3 of Document Number 88422. The SMB10J15AHM3_B/H is not a variant - it is the exact orderable part number defined in Vishay's official documentation.
How does SMB10J15AHM3_B/H compare to SMBJ15A in terms of surge capability?
SMB10J15AHM3_B/H delivers 1000 W peak pulse power (PPPM) under 10/1000 µs waveform, whereas SMBJ15A is rated for 600 W. Both share identical VWM (15 V), VBR (16.7–18.5 V), and VC (24.4 V), but SMB10J15AHM3_B/H achieves higher power handling via optimized chip geometry and thermal design in the same SMB footprint. This difference is critical for ISO 7637-2 pulse 5a (load dump) compliance in automotive applications, where SMB10J15AHM3_B/H meets full specification while SMBJ15A does not.
What is the maximum operating temperature for SMB10J15AHM3_B/H?
The SMB10J15AHM3_B/H has a maximum junction temperature (TJ max) of +150 °C, as specified in the Maximum Ratings table (page 1) of Vishay Document Number 88422. This rating enables reliable operation in under-hood automotive environments and sealed industrial enclosures. Derating curves in Figure 2 confirm usable power capability down to 50% of rated PPPM at 125 °C ambient, provided PCB copper pad area meets the 0.2″ × 0.2″ (5.0 mm × 5.0 mm) minimum requirement.
