Product details
Overview
SMB10J15AHM3_A/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), 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 I/O protection.
For engineers reviewing the SMB10J15AHM3_A/I datasheet, SMB10J15AHM3_A/I pinout, SMB10J15AHM3_A/I application, or SMB10J15AHM3_A/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 72 °C/W), junction temperature limit (TJ max = 150 °C), and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker test.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents <1 µA leakage at 15 V (VWM), then rapidly avalanches when transient voltage exceeds 16.7 V (min VBR), limiting downstream voltage to ≤24.4 V at 41 A surge. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Designed for surface-mount automated placement, SMB10J15AHM3_A/I meets MSL Level 1 (260 °C reflow peak) and is qualified to AEC-Q101 for automotive use. The matte tin-plated leads comply with J-STD-002 and JESD22-B102 solderability standards, and its DO-214AA outline enables compact PCB layout with 5.0 mm × 5.0 mm copper pad thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin for 12 V automotive systems. |
| VBR (min/max) | 16.7 V / 18.5 V at 1 mA - precise avalanche onset range ensuring reliable triggering without premature conduction. |
| VC @ IPPM | 24.4 V at 41 A - clamped voltage during 10/1000 µs surge; limits stress on protected ICs like CAN transceivers or microcontrollers. |
| PPPM | 1000 W - peak pulse power handling capacity; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity with proper layout. |
| IFSM | 100 A - non-repetitive forward surge rating; accommodates inrush or fault currents without bond wire failure. |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |
| RθJA | 72 °C/W - thermal resistance junction-to-ambient; requires ≥5.0 mm × 5.0 mm copper pads per terminal for rated power dissipation. |
Pinout & Package

Applications
| Automotive Sensor Power Protection | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: Protecting 12 V supply lines feeding ABS wheel speed sensors or oxygen sensors exposed to load dump and ISO 7637-2 pulses.

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), and PPPM (1000 W); differs only in packaging suffix (E3 vs HM3) - RoHS-compliant but not halogen-free. | Lacks halogen-free certification and JESD201 Class 2 whisker resistance; acceptable for commercial, non-automotive designs. | Select when halogen-free compliance is not required and cost optimization is prioritized over automotive qualification. |
| 1.5SMC15A | Same electrical specs (VWM = 15 V, VC = 24.4 V, PPPM = 1000 W) but in larger SMC (DO-214AB) package - 2.5× higher RθJA (180 °C/W) and 2.5× footprint area. | Requires significantly larger PCB real estate and reduced thermal performance; unsuitable for dense automotive modules. | Choose only if existing SMC footprint is fixed and thermal derating can be accommodated via oversized copper pours. |
Compared with SMBJ15AHE3_A/H and 1.5SMC15A, SMB10J15AHM3_A/I uniquely combines AEC-Q101 qualification, halogen-free construction, MSL Level 1 compatibility, and SMB footprint - making it the optimal choice for next-generation automotive electronics where material compliance and space constraints are co-driven requirements.

FAQ
What is the maximum clamping voltage of SMB10J15AHM3_A/I at its rated peak pulse current?
The SMB10J15AHM3_A/I has a maximum clamping voltage (VC) of 24.4 V when subjected to its rated peak pulse current (IPPM) of 41 A using the standard 10/1000 µs waveform. This value is measured under defined test conditions per ANSI/IEEE C62.35 and ensures predictable voltage limiting for downstream components such as microcontrollers or CAN transceivers. The SMB10J15AHM3_A/I maintains this clamping performance across its qualified operating temperature range.
Is SMB10J15AHM3_A/I qualified for automotive applications?
Yes, SMB10J15AHM3_A/I is AEC-Q101 qualified, meaning it has passed rigorous stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing - all required for automotive under-hood and cabin applications. The "HM3" suffix explicitly denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction, distinguishing it from commercial-grade variants. This makes SMB10J15AHM3_A/I suitable for use in engine control units, body control modules, and ADAS sensor power supplies.
What does the "HM3" suffix mean in SMB10J15AHM3_A/I?
The "HM3" suffix in SMB10J15AHM3_A/I indicates halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance and AEC-Q101 qualification. It replaces the older "HE3" (RoHS + AEC-Q101) and "M3" (halogen-free + RoHS) suffixes by combining both environmental and automotive reliability attributes. The "_A/I" denotes tape-and-reel packaging in 13-inch reels (3200 units), with "I" specifying the reel size and orientation code per Vishay's ordering convention.
How does SMB10J15AHM3_A/I compare to bidirectional TVS diodes in the same family?
SMB10J15AHM3_A/I is unidirectional and optimized for DC power rail protection where polarity is fixed - offering higher peak pulse power (1000 W vs 800 W for bidirectional SMB8J15CA) and lower clamping voltage at equivalent current. Bidirectional variants like SMB8J15CA are intended for AC or differential signal lines (e.g., RS-485, USB D+/D−) but sacrifice 20 % power rating and exhibit slightly higher VC due to dual-junction architecture. SMB10J15AHM3_A/I should not be substituted for bidirectional use without circuit redesign.
What PCB layout guidelines apply to SMB10J15AHM3_A/I for optimal thermal and surge performance?
For SMB10J15AHM3_A/I, Vishay specifies minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 1000 W pulse power and 72 °C/W thermal resistance. Traces must be short and wide to minimize inductance; avoid vias in series with the TVS path. Ground plane beneath the device improves heat spreading and reduces impedance. The cathode band must align with the designated high-side net, and no silkscreen or solder mask should cover pad edges to ensure full solder wetting per J-STD-002.
