Product details
Overview
SMB10J15AHM3/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 DC power rails and signal lines. It features a 15 V stand-off voltage (VWM), 24.4 V maximum clamping voltage (VC) at 41.0 A peak pulse current (IPPM), 1000 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMB10J15AHM3/I datasheet, SMB10J15AHM3/I pinout, SMB10J15AHM3/I application, or SMB10J15AHM3/I equivalent, this device is selected for robust overvoltage protection in automotive ECUs, industrial sensor interfaces, and 12 V/24 V power supply inputs where low leakage (<1.0 µA at VWM), fast response, and halogen-free RoHS compliance are required.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents <1.0 µA reverse leakage at 15 V; during transients exceeding its 16.7–18.5 V breakdown range (IT = 1.0 mA), it clamps to ≤24.4 V while diverting up to 41.0 A (10/1000 µs). Its glass-passivated junction ensures stable parametric performance across temperature (–55 °C to +150 °C).
The SMB10J15AHM3/I uses a low-profile DO-214AA package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, rated MSL Level 1 (260 °C peak reflow), and qualified to AEC-Q101 for automotive under-hood applications. Its thermal resistance is 72 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads.
Key Specifications

|---|---|
| VWM | 15 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin for 12 V systems. |
| VBR min/max | 16.7 V / 18.5 V - Breakdown occurs within this range at 1.0 mA test current; ensures reliable turn-on above nominal rail. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A-E3/52 | Same VWM (15 V), VC = 24.4 V, but rated for commercial grade only (not AEC-Q101); RoHS-compliant but not halogen-free. | Lacks automotive qualification and halogen-free certification; suitable for industrial/commercial designs without automotive compliance needs. | Select when AEC-Q101 and halogen-free requirements are absent and cost optimization is prioritized. |
| 1.5SMC15A | Same electrical specs (VWM = 15 V, VC = 24.4 V, PPPM = 1000 W), but in larger SMC (DO-214AB) package; higher RθJA (50 °C/W vs. 72 °C/W). | Requires more PCB area and has lower power density; less suitable for space-constrained automotive modules. | Choose only if existing layout uses SMC footprint or higher thermal mass is needed for extended surge duty cycles. |

FAQ
What is the clamping voltage of SMB10J15AHM3/I at its rated peak pulse current?
The SMB10J15AHM3/I clamps to a maximum of 24.4 V at its rated peak pulse current of 41.0 A (10/1000 µs waveform). This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The SMB10J15AHM3/I maintains this clamping performance across its operational temperature range and after repeated surge exposures per AEC-Q101 stress testing.
Is SMB10J15AHM3/I suitable for automotive applications?
Yes, SMB10J15AHM3/I is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor modules. Its HM3 suffix denotes halogen-free, RoHS-compliant construction meeting automotive environmental requirements. The SMB10J15AHM3/I also meets MSL Level 1 for lead-free reflow compatibility and operates reliably from –55 °C to +150 °C junction temperature.
How does the SMB10J15AHM3/I differ from the SMBJ15A series?
The SMB10J15AHM3/I shares identical electrical parameters (VWM = 15 V, VC = 24.4 V, PPPM = 1000 W) with SMBJ15A but adds AEC-Q101 qualification and halogen-free (HM3) construction. Unlike commercial-grade SMBJ15A-E3/52, the SMB10J15AHM3/I is validated for automotive under-hood environments and supports stricter environmental compliance mandates without sacrificing surge performance.
What is the reverse leakage current of SMB10J15AHM3/I at its stand-off voltage?
The SMB10J15AHM3/I exhibits a maximum reverse leakage current of 1.0 µA at its 15 V stand-off voltage (VWM), measured at 25 °C. This ultra-low leakage minimizes standby power loss in always-on automotive modules and preserves accuracy in high-impedance sensor signal paths. Leakage remains below 5.0 µA across the full –55 °C to +125 °C operating range.
What package type does SMB10J15AHM3/I use, and what are its key mechanical features?
SMB10J15AHM3/I uses the SMB (DO-214AA) surface-mount package: dimensions 4.57 mm × 3.94 mm × 2.20 mm, with a cathode band marking. Its matte tin-plated leads comply with J-STD-002 solderability standards and JESD 22-B102 whisker resistance (Class 2). The package is rated MSL Level 1 (260 °C peak reflow) and features UL 94 V-0 molding compound for flame resistance.
