Product details
Overview
SMB10J15AHM3_B/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 15 V standoff voltage (VWM), 16.7–18.5 V breakdown range (VBR), and 1000 W peak pulse power (PPPM) at 10/1000 µs. It delivers clamping voltage of 24.4 V at 41.0 A peak surge current and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the SMB10J15AHM3_B/I datasheet, SMB10J15AHM3_B/I pinout, SMB10J15AHM3_B/I application, or SMB10J15AHM3_B/I equivalent, key selection criteria include clamping performance under 10/1000 µs transients, junction temperature derating above 25 °C, unidirectional polarity marking, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients. Its unidirectional configuration provides forward conduction capability while clamping reverse overvoltage events.
Thermal design relies on RθJA = 72 °C/W (typ.) and RθJL = 20 °C/W (typ.), requiring minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated 1000 W dissipation. It operates across -55 °C to +150 °C junction temperature range and meets MSL Level 1 per J-STD-020.

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), and PPPM (1000 W); E3 suffix indicates standard RoHS, not halogen-free | Lacks halogen-free certification; suitable for commercial but not automotive-grade material compliance requirements | Select when halogen-free content is not mandated and cost optimization is prioritized |
| SMB10J15A-M3/5B | Identical electrical specs; M3 suffix denotes halogen-free RoHS, but packaging is 13" reel (3200 pcs) vs. I-code (3200 pcs, tape-and-reel) | Different packaging code only; no functional or reliability difference; same AEC-Q101 qualification | Select when procurement prefers alternate reel size or distributor-specific packaging format |
Compared with SMB10J15AHM3_B/I, SMBJ15AHE3_A/H omits halogen-free assurance while retaining identical clamping and surge ratings, whereas SMB10J15A-M3/5B matches all specifications and qualifications but uses a different packaging identifier-making it a functionally identical alternative with logistics-level variation only.

FAQ
What is the clamping voltage of SMB10J15AHM3_B/I at its rated peak pulse current?
The SMB10J15AHM3_B/I has a maximum clamping voltage (VC) of 24.4 V when subjected to its rated peak pulse current (IPPM) of 41.0 A under the standard 10/1000 µs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during surge events, ensuring downstream components remain within safe operating limits.
Is SMB10J15AHM3_B/I suitable for automotive applications?
Yes, SMB10J15AHM3_B/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction. It is explicitly rated for automotive use per Vishay's documentation and supports operation from -55 °C to +150 °C junction temperature, making it appropriate for engine control units, body electronics, and ADAS sensor modules.
What does the "HM3" suffix mean in SMB10J15AHM3_B/I?
The "HM3" suffix in SMB10J15AHM3_B/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. The "H" indicates automotive grade, "M3" specifies halogen-free materials meeting IEC 61249-2-21, and the "_B/I" identifies the packaging variant: 13-inch tape-and-reel with 3200 units per reel.
How does SMB10J15AHM3_B/I differ from bidirectional TVS diodes like SMB8J15CA?
SMB10J15AHM3_B/I is unidirectional and conducts forward current like a rectifier, while SMB8J15CA is bidirectional and symmetrical for AC-line or data-line protection. SMB10J15AHM3_B/I offers higher PPPM (1000 W vs. 800 W) and is optimized for DC power rail protection, whereas SMB8J15CA supports dual-polarity transients but with reduced surge rating.
What PCB layout guidance applies to SMB10J15AHM3_B/I for optimal thermal performance?
For rated 1000 W pulse power handling, Vishay specifies mounting SMB10J15AHM3_B/I on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Use short, wide traces to minimize inductance, ensure solid thermal vias under pads if using internal layers, and avoid thermal relief patterns that impede heat transfer from the SMB (DO-214AA) package body.
