Product details
Overview
SMB10J5.0AHM3_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 with 1000 W peak pulse power (10/1000 µs), 6.4 V minimum breakdown voltage, and 9.2 V maximum clamping voltage at 108.7 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMB10J5.0AHM3_B/H datasheet, SMB10J5.0AHM3_B/H pinout, SMB10J5.0AHM3_B/H application, or SMB10J5.0AHM3_B/H equivalent, this AEC-Q101 qualified, halogen-free, RoHS-compliant TVS offers verified clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for automotive-grade board-level ESD and load-dump protection design.
Technical Context
This device operates as a unidirectional avalanche diode, triggering at 6.4–7.07 V (VBR) with 5.0 V stand-off voltage (VWM) and ≤1000 µA reverse leakage at rated VWM. Its glass-passivated junction ensures stable breakdown and fast response (<1 ns) to transients induced by inductive switching or lightning surges.
Thermally, it features RθJA = 72 °C/W and RθJL = 20 °C/W, enabling reliable operation up to +150 °C junction temperature. The SMB package supports automated placement and meets UL 94 V-0 flammability rating with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMB10J5.0AHE3_B/H | Same electrical specs; RoHS-compliant but not halogen-free; no AEC-Q101 qualification | Suitable for commercial/industrial use where automotive qualification is not required | Select when cost sensitivity outweighs halogen-free or automotive compliance needs |
| SMAJ5.0A | Lower PPPM (400 W), smaller SMA package, higher VC (13.4 V), same VWM/VBR range | Limited to lower-energy transients; unsuitable for automotive load-dump per ISO 7637-2 | Choose only for space-constrained consumer applications with <400 W surge exposure |
Compared with SMB10J5.0AHE3_B/H and SMAJ5.0A, SMB10J5.0AHM3_B/H uniquely combines 1000 W surge handling, AEC-Q101 qualification, and halogen-free construction - making it the only option among the three for production automotive modules requiring full compliance and robustness.

FAQ
What is the clamping voltage of SMB10J5.0AHM3_B/H at its rated peak pulse current?
The SMB10J5.0AHM3_B/H has a maximum clamping voltage (VC) of 9.2 V at its rated peak pulse current of 108.7 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 standards and guarantees that protected circuits will not experience voltages exceeding 9.2 V during worst-case surge events, preserving downstream IC integrity. The SMB10J5.0AHM3_B/H achieves this with low incremental surge resistance inherent to its glass-passivated junction structure.
Is SMB10J5.0AHM3_B/H suitable for automotive applications?
Yes, SMB10J5.0AHM3_B/H is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials - meeting key requirements for automotive electronics. Its 1000 W peak pulse power, −55 °C to +150 °C operating range, and MSL Level 1 rating make it appropriate for under-hood and body-control applications subject to ISO 7637-2 load-dump pulses. The HM3 suffix explicitly denotes this qualification, and the SMB10J5.0AHM3_B/H data sheet confirms compliance per revision 09-Jan-2024.
What does the "HM3" suffix indicate in SMB10J5.0AHM3_B/H?
The "HM3" suffix in SMB10J5.0AHM3_B/H identifies a halogen-free, RoHS-compliant, and AEC-Q101 qualified variant per Vishay's ordering nomenclature. It distinguishes this part from commercial-grade versions (e.g., E3 or M3) and confirms full automotive qualification, material compliance, and traceability. The "B/H" denotes packaging: 7″ tape-and-reel, 750-unit quantity, with "B" indicating reel orientation and "H" the preferred package code. This exact suffix appears in Vishay Document Number 88422, Table "ORDERING INFORMATION".
How does SMB10J5.0AHM3_B/H differ from bidirectional TVS diodes like SMB8J5.0CA?
SMB10J5.0AHM3_B/H is unidirectional, with polarity defined by a cathode band and optimized for clamping positive transients on grounded-line configurations. In contrast, SMB8J5.0CA is bidirectional (no polarity marking), offering symmetric clamping for AC-coupled or floating lines. SMB10J5.0AHM3_B/H delivers 1000 W PPPM vs. 800 W for SMB8J5.0CA, and its 108.7 A IPPM exceeds SMB8J5.0CA's 87.0 A. These differences make SMB10J5.0AHM3_B/H preferable for 5 V DC rail protection where unidirectional behavior and higher surge margin are required.
What thermal derating applies to SMB10J5.0AHM3_B/H above 25 °C ambient?
SMB10J5.0AHM3_B/H must be derated linearly above 25 °C ambient per Figure 2 in Vishay Document 88422: peak pulse power decreases by approximately 0.8% per °C rise, reaching ~50% of rated 1000 W at +125 °C case temperature. This derating stems from its RθJA of 72 °C/W and maximum TJ of +150 °C. Designers must verify PCB copper area (minimum 5.0 mm × 5.0 mm per pad) and airflow to maintain safe junction temperatures - especially in sealed automotive enclosures where SMB10J5.0AHM3_B/H is commonly deployed.
