Product details
Overview
SMB10J6.5AHM3/H 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 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR) at 10 mA, 11.2 V clamping voltage (VC) at 89.3 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMB10J6.5AHM3/H datasheet, SMB10J6.5AHM3/H pinout, SMB10J6.5AHM3/H application, or SMB10J6.5AHM3/H equivalent, key selection criteria include AEC-Q101 qualification, halogen-free RoHS compliance (HM3 suffix), unidirectional polarity with cathode band marking, and thermal resistance (RθJA = 72 °C/W) for PCB-level thermal design validation.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold, limiting transient overvoltage to ≤11.2 V at 89.3 A. Its glass-passivated junction ensures stable leakage (<5 µA at VWM) and fast response time (<1 ns), critical for protecting MOSFET gates and microcontroller I/O against ESD and inductive switching spikes.
Rated for -55 °C to +150 °C junction temperature and qualified per AEC-Q101, SMB10J6.5AHM3/H supports automotive-grade reliability under repeated surge stress. The SMB package enables automated SMT placement and meets UL 94 V-0 flammability, with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse operating voltage before clamping begins; sets upper limit for protected circuit's normal DC rail. |
| VBR min/max | 7.22 V / 7.98 V at IT = 10 mA - tight breakdown tolerance ensures predictable turn-on across temperature and production lot. |
| VC @ IPPM | 11.2 V at 89.3 A - clamping voltage during 10/1000 µs surge defines worst-case overvoltage seen by downstream ICs. |
| PPPM | 1000 W - peak pulse power handling capacity determines survivability against ISO 7637-2 Pulse 1/2a/5a transients. |
| IR @ VWM | ≤5 µA - ultra-low reverse leakage preserves battery life in always-on automotive modules and low-power sensor nodes. |
| TJ max | +150 °C - extended junction temperature rating enables use in engine bay and under-hood applications without derating. |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height for high-density layout. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by color band on one end; polarity-critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; forms current path during avalanche conduction. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 12 V rail or CAN_H); carries full surge current into anode during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD-HBM ≥8 kV - enables direct use in Tier-1 ECU designs. |
| Halogen-free & RoHS-compliant (HM3) | Meets IEC 61249-2-21 and JEDEC JS709E; eliminates brominated flame retardants while maintaining UL 94 V-0 rating. |
| Low incremental surge resistance | Enables tighter VC/VBR ratio (11.2 V / 7.22 V ≈ 1.55), minimizing let-through energy during fast transients compared to higher-ratio TVS devices. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns - no baking required pre-assembly. |
| Glass-passivated junction | Provides stable electrical parameters over lifetime and immunity to humidity-induced parameter drift in harsh environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5AHE3/A | Same VWM (6.5 V), VBR (7.22–7.98 V), and PPPM (1000 W), but E3 suffix indicates standard RoHS (not halogen-free) and non-AEC-Q101 rated. | Limited to commercial/industrial use; not approved for automotive production due to missing AEC-Q101 qualification. | Select SMBJ6.5AHE3/A only for cost-sensitive non-automotive designs where halogen content and automotive qualification are not mandated. |
| SMAJ6.5A-HM3 | Same HM3 halogen-free and AEC-Q101 status, but SMA package (smaller footprint, lower PPPM = 400 W, higher VC = 11.5 V at 34.7 A). | Insufficient power handling for ISO 7637-2 Pulse 5a; suitable only for low-energy ESD or low-current signal-line protection. | Choose SMAJ6.5A-HM3 only when board space is constrained and surge threat level is limited to IEC 61000-4-2 ESD, not automotive load dump. |
Compared with SMBJ6.5AHE3/A and SMAJ6.5A-HM3, SMB10J6.5AHM3/H uniquely delivers automotive-grade reliability, halogen-free compliance, and 1000 W surge capacity in the SMB form factor - making it the only option qualified for under-hood power rail protection where all three attributes are mandatory.

FAQ
What is the clamping voltage of SMB10J6.5AHM3/H at its rated peak pulse current?
The SMB10J6.5AHM3/H has a maximum clamping voltage (VC) of 11.2 V when subjected to its rated peak pulse current (IPPM) of 89.3 A using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMB10J6.5AHM3/H maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C), ensuring consistent protection in automotive under-hood environments.
Is SMB10J6.5AHM3/H suitable for automotive applications?
Yes, SMB10J6.5AHM3/H is explicitly AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials (HM3 suffix), making it approved for automotive production use. Its 1000 W peak pulse power rating, -55 °C to +150 °C operating range, and validated performance under HTOL and temperature cycling confirm suitability for engine control units, body electronics, and ADAS sensor modules. The SMB10J6.5AHM3/H meets ISO 7637-2 and ISO 16750-2 transient immunity requirements when applied per Vishay's recommended PCB layout guidelines.
How does the HM3 suffix differ from the E3 or M3 suffix in Vishay TVS diodes?
The HM3 suffix in SMB10J6.5AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification - distinguishing it from E3 (RoHS-compliant, commercial grade) and M3 (halogen-free RoHS, commercial grade). Only HM3 and HE3 variants carry AEC-Q101 certification. The HM3 variant also passes JESD 201 Class 2 whisker testing and supports lead-free reflow up to 260 °C (MSL Level 1), enabling direct integration into automotive manufacturing lines without process deviation. SMB10J6.5AHM3/H thus provides the highest reliability tier in Vishay's SMB10J family.
What is the reverse leakage current specification for SMB10J6.5AHM3/H at its stand-off voltage?
SMB10J6.5AHM3/H exhibits a maximum reverse leakage current (ID) of 5 µA at its stand-off voltage (VWM) of 6.5 V and ambient temperature of 25 °C. This ultra-low leakage is critical for battery-powered automotive modules and always-on sensor circuits, where cumulative leakage across multiple protection devices could otherwise drain standby current budgets. The SMB10J6.5AHM3/H maintains leakage below 10 µA up to 85 °C, supporting reliable operation in cabin and under-dash environments.
Can SMB10J6.5AHM3/H be used in bidirectional configurations?
No, SMB10J6.5AHM3/H is a unidirectional TVS diode, identified by its cathode band marking and specified electrical characteristics (e.g., forward surge rating IFSM = 100 A) that apply only in reverse-biased clamping mode. For bidirectional protection, Vishay offers the SMB8J6.5CAHM3/H variant - same package and HM3 qualification but symmetric breakdown behavior. Using SMB10J6.5AHM3/H in bidirectional applications risks forward conduction and permanent damage during positive transients; always verify polarity alignment in schematic and layout for SMB10J6.5AHM3/H.
