Product details
Overview
SMB10J5.0AHM3_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 5.0 V DC power rails and signal lines. It delivers 1000 W peak pulse power (10/1000 µs), clamps transients to ≤9.2 V at 108.7 A, and features AEC-Q101 qualification for automotive electronics.
For engineers reviewing the SMB10J5.0AHM3_A/I datasheet, SMB10J5.0AHM3_A/I pinout, SMB10J5.0AHM3_A/I application, or SMB10J5.0AHM3_A/I equivalent, key selection criteria include stand-off voltage (5.0 V), breakdown voltage range (6.4–7.07 V), clamping performance under 108.7 A surge, and halogen-free RoHS-compliant construction with M3 suffix.
Technical Context
This device operates as a unidirectional avalanche diode, activated when reverse voltage exceeds its breakdown threshold (VBR = 6.4–7.07 V at IT = 10 mA). Its low incremental surge resistance and fast response time enable effective suppression of ESD, lightning-induced surges, and inductive switching transients.
Thermal design relies on junction-to-lead thermal resistance of 20 °C/W and junction-to-ambient of 72 °C/W, requiring minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. The matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMB10J5.0AHE3_B/I | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs HM3) | Lacks halogen-free certification required for some Tier 1 automotive programs | Select when halogen-free content is not mandated and cost optimization is prioritized |
| SMAJ5.0A-M3 | Lower PPPM (400 W), smaller SMA package (DO-214AC), same VWM/VBR | Insufficient for 1000 W load-dump scenarios; suitable only for lower-energy ESD zones | Choose only for space-constrained consumer designs where full automotive surge immunity is not required |
Compared with SMB10J5.0AHE3_B/I, SMB10J5.0AHM3_A/I adds halogen-free compliance without sacrificing clamping or power rating; versus SMAJ5.0A-M3, it provides 2.5× higher surge capacity in a slightly larger but thermally superior SMB package.

FAQ
What is the clamping voltage of SMB10J5.0AHM3_A/I at its rated peak pulse current?
The SMB10J5.0AHM3_A/I clamps to a maximum of 9.2 V when subjected to its rated peak pulse current of 108.7 A (10/1000 µs waveform). This value is measured under standardized test conditions and ensures downstream 5 V logic circuits remain within safe operating limits during surge events. The SMB10J5.0AHM3_A/I achieves this with minimal voltage overshoot due to its low incremental surge resistance.
Is SMB10J5.0AHM3_A/I suitable for automotive applications?
Yes, SMB10J5.0AHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction-meeting Tier 1 automotive supply chain requirements. Its −55 °C to +150 °C operating range, robust surge capability (1000 W), and MSL Level 1 reflow compatibility make SMB10J5.0AHM3_A/I appropriate for under-hood and cabin modules including BCMs and infotainment systems.
How does the HM3 suffix differ from the HE3 suffix in SMB10J5.0A variants?
The HM3 suffix denotes halogen-free, RoHS-compliant construction with whisker-resistant plating (JESD 201 Class 2), whereas HE3 indicates RoHS compliance without halogen-free assurance. Both are AEC-Q101 qualified, but SMB10J5.0AHM3_A/I satisfies stricter environmental mandates for modern automotive platforms where brominated flame retardants are prohibited. The electrical and thermal specs remain identical between HM3 and HE3 versions.
What is the recommended PCB pad layout for SMB10J5.0AHM3_A/I?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad area for each terminal of SMB10J5.0AHM3_A/I to ensure adequate thermal dissipation and mechanical reliability during surge events. This layout supports the device's 72 °C/W junction-to-ambient thermal resistance and prevents solder joint fatigue under repeated thermal stress. The SMB10J5.0AHM3_A/I datasheet provides exact dimensional tolerances for land patterns in inches and millimeters.
Can SMB10J5.0AHM3_A/I be used in bidirectional configurations?
No, SMB10J5.0AHM3_A/I is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional protection requires a part with "C" in the designation (e.g., SMB8J5.0CA). Using SMB10J5.0AHM3_A/I in reverse-biased AC applications would result in forward conduction and potential failure. For symmetric surge protection, select a verified bidirectional variant-not SMB10J5.0AHM3_A/I.
