Product details
Overview
SMB10J15AHM3_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 power 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 sensor interfaces and industrial power supply rails.
For engineers reviewing the SMB10J15AHM3_A/H datasheet, SMB10J15AHM3_A/H pinout, SMB10J15AHM3_A/H application, or SMB10J15AHM3_A/H equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity, low clamping ratio (VC/VWM ≈ 1.63), MSL Level 1 moisture sensitivity, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This device operates as a silicon avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response time and stable clamping under repetitive transients. Its thermal resistance (RθJL = 20 °C/W) supports reliable operation up to TJ = +150 °C when mounted on 5.0 mm × 5.0 mm copper pads.
The SMB10J15AHM3_A/H is rated for non-repetitive 8.3 ms half-sine surge current up to 100 A (IFSM), with reverse leakage ≤1.0 µA at VWM and junction capacitance not specified - confirming its suitability for DC-biased protection rather than high-frequency signal line applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin for protected circuitry |
| VBR min/max | 16.7 V / 18.5 V at IT = 1 mA - tight breakdown tolerance ensures predictable turn-on during overvoltage events |
| VC @ IPPM | 24.4 V at 41 A - clamping voltage limits downstream voltage stress during 1000 W surge, enabling robust IC-level protection |
| PPPM | 1000 W (10/1000 µs) - high energy absorption capacity suitable for automotive load-dump and inductive switching transients |
| IFSM | 100 A (8.3 ms half-sine) - withstands single-event high-current surges without failure, critical for power rail protection |
| TJ max | +150 °C - extended junction temperature rating supports under-hood automotive and industrial environments |
| 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 plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance. Polarity indicated by cathode band (banded end = cathode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts during forward surge or fault conditions |
| Cathode | Reverse-biased clamping terminal | Connected to higher-potential side; avalanches into low-impedance state during overvoltage to clamp voltage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMB10J15AHE3_A/H | Same electrical specs, but RoHS-compliant commercial grade (E3); lacks AEC-Q101 qualification and halogen-free certification | Approved for industrial/commercial designs only; not permitted in automotive OEM or Tier-1 BOMs requiring AEC-Q101 | Select when cost sensitivity outweighs automotive qualification needs and halogen-free requirement is waived |
| SMBJ15A-T | Identical VWM (15 V), VC (24.4 V), and PPPM (1000 W); same SMB package but from Diodes Inc.; no AEC-Q101 data published | Used in telecom and computing where automotive qualification is unnecessary; may require additional qualification for automotive deployment | Consider for dual-sourcing where Vishay supply constraints exist, pending internal AEC-Q101 validation |
Compared with SMB10J15AHM3_A/H, the HE3 variant trades automotive qualification for lower cost, while SMBJ15A-T offers second-source availability but requires customer-led AEC-Q101 validation for automotive use - making SMB10J15AHM3_A/H the only drop-in qualified solution for safety-critical vehicle systems.

FAQ
What is the clamping voltage of SMB10J15AHM3_A/H at its rated peak pulse current?
The SMB10J15AHM3_A/H has a maximum clamping voltage (VC) of 24.4 V at 41 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuitry during surge events - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings.
Is SMB10J15AHM3_A/H suitable for automotive applications?
Yes, SMB10J15AHM3_A/H is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, ADAS sensors, and body electronics. Its halogen-free (HM3) construction, MSL Level 1 rating, and validated performance across -55 °C to +150 °C junction temperature make it compliant with OEM requirements for under-hood and cabin-mounted systems.
What does the "HM3" suffix indicate in SMB10J15AHM3_A/H?
The "HM3" suffix in SMB10J15AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from E3 (RoHS-compliant commercial) and HE3 (RoHS-compliant AEC-Q101) versions - confirming full compliance with automotive environmental and reliability standards, including JESD 201 Class 2 whisker resistance and LF peak reflow at 260 °C.
How does SMB10J15AHM3_A/H differ from bidirectional TVS diodes like SMB8J15CA?
SMB10J15AHM3_A/H is unidirectional and optimized for DC-biased lines where only negative-going transients must be suppressed, offering higher PPPM (1000 W vs. 800 W) and lower clamping voltage than its bidirectional counterpart SMB8J15CA. The unidirectional configuration provides superior performance on power rails and single-ended signal paths, whereas SMB8J15CA suits AC-coupled or symmetric line protection.
What PCB layout guidance applies to SMB10J15AHM3_A/H for optimal thermal and electrical performance?
For optimal performance, mount SMB10J15AHM3_A/H on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. This pad size ensures adequate heat dissipation (RθJL = 20 °C/W) and maintains surge current handling capability. Avoid narrow traces between the device and protected node to minimize inductance and preserve clamping speed.
