Product details
Overview
SMB10J6.5-E3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on DC power rails and signal lines. It features 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 power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMB10J6.5-E3/5B datasheet, SMB10J6.5-E3/5B pinout, SMB10J6.5-E3/5B application, or SMB10J6.5-E3/5B equivalent, key selection criteria include clamping performance under 100 A surge, RoHS-compliant matte tin terminations, AEC-Q101 qualification status, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (7.22–7.98 V), it avalanches to limit transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable leakage (<1000 µA at VWM) and low incremental surge resistance for consistent clamping.
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 meets MSL Level 1 (260 °C peak reflow) and JESD201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse operating voltage before significant leakage; sets safe DC rail margin. |
| VBR (min/max) | 7.22 V / 7.98 V at 10 mA - tight breakdown window ensures predictable turn-on during transients. |
| VC @ IPPM | 11.2 V at 89.3 A - clamping voltage defines worst-case overvoltage seen by protected ICs during 10/1000 µs surge. |
| PPPM | 1000 W - peak pulse power rating with 10/1000 µs waveform; determines single-event surge handling capability. |
| ID @ VWM | ≤1000 µA - reverse leakage at stand-off voltage; critical for low-power sensor line integrity. |
| TJ max. | 150 °C - maximum junction temperature; enables operation in under-hood automotive environments. |
| Package | DO-214AA (SMB) - industry-standard surface-mount outline with cathode band marking and 2.16 mm height. |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with two leads, cathode identified by a color band on the body end. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for thermal and surge performance compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to system ground or lowest potential point; completes shunt path during avalanche conduction. |
| Cathode | Protected line input | Connected to line being protected (e.g., 5 V rail or sensor output); carries full surge current into anode during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan. |
| Glass passivated junction | Ensures stable VBR tolerance and long-term leakage stability across 150 °C operating range. |
| MSL Level 1 (260 °C) | Compatible with standard lead-free reflow profiles without preconditioning or baking requirements. |
| Matte tin plating | Meets J-STD-002 solderability and JESD22-B102 mechanical adhesion standards; Class 1A whisker resistant. |
| UL 94 V-0 molding compound | Flame-retardant encapsulation required for automotive and industrial safety certifications. |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A | Same VWM (6.5 V), identical DO-214AA package, but lower PPPM (600 W) and higher VC (11.4 V at 53.5 A). | Not AEC-Q101 qualified; suitable only for commercial-grade consumer or computing applications. | Select SMBJ6.5A only if surge energy is limited to ≤600 W and automotive qualification is not required. |
| 1.5SMC6.5A | Higher package thermal mass (DO-214AB), same VWM, but lower clamping (10.5 V at 95.2 A) and higher PPPM (1500 W). | Larger footprint (7.11 mm × 6.22 mm vs. 4.57 mm × 3.94 mm); incompatible with space-constrained SMB layouts. | Choose 1.5SMC6.5A only when board area permits larger package and clamping voltage margin must be tightened below 11.2 V. |
Compared with SMBJ6.5A, SMB10J6.5-E3/5B delivers +67% peak power handling and automotive qualification; versus 1.5SMC6.5A, it saves >40% PCB area while maintaining sub-12 V clamping - making it optimal for AEC-Q101-compliant compact power rails.

FAQ
What is the clamping voltage of SMB10J6.5-E3/5B and how is it measured?
The SMB10J6.5-E3/5B has a maximum clamping voltage (VC) of 11.2 V, measured at 89.3 A peak pulse current (IPPM) using a 10/1000 µs waveform per ANSI/IEEE C62.35. This value represents the worst-case voltage imposed on the protected circuit during a standardized surge event - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings. The SMB10J6.5-E3/5B achieves this clamping performance while maintaining low incremental surge resistance.
Is SMB10J6.5-E3/5B qualified for automotive applications?
Yes, SMB10J6.5-E3/5B is AEC-Q101 qualified, meaning it has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per the AEC-Q101 standard. This qualification confirms its suitability for under-hood and cabin-mounted automotive electronics where reliability under thermal and electrical stress is mandatory. The SMB10J6.5-E3/5B is explicitly listed in Vishay's AEC-Q101 qualified product list with HE3 suffix variants, and the E3/5B variant shares the same die and construction.
What is the difference between SMB10J6.5-E3/5B and SMBJ6.5A?
SMB10J6.5-E3/5B delivers 1000 W peak pulse power (PPPM) versus 600 W for SMBJ6.5A, with tighter clamping (11.2 V vs. 11.4 V at respective IPPM) and AEC-Q101 qualification - whereas SMBJ6.5A is commercial-grade only. Both use DO-214AA packages and share 6.5 V VWM, but SMB10J6.5-E3/5B's higher surge rating and automotive qualification make it appropriate for demanding applications where SMBJ6.5A would fail prematurely. The SMB10J6.5-E3/5B also features JESD201 Class 1A whisker resistance.
What PCB pad layout is required for SMB10J6.5-E3/5B to achieve rated 1000 W performance?
To achieve the full 1000 W peak pulse power rating, SMB10J6.5-E3/5B must be mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay Document 88422. Smaller pads reduce thermal dissipation and derate both power and current handling - e.g., at 75 °C ambient, the device's IPPM drops to ~70 A. The pad layout directly impacts RθJA (72 °C/W typ.), so adherence to the recommended footprint is essential for reliable surge suppression in automotive and industrial designs using SMB10J6.5-E3/5B.
Does SMB10J6.5-E3/5B have RoHS and halogen-free compliance?
Yes, SMB10J6.5-E3/5B is RoHS-compliant per Directive 2011/65/EU and halogen-free per JEDEC JS709A. The "E3" suffix explicitly denotes RoHS-compliant matte tin plating, and Vishay certifies all E3-suffix parts as meeting both requirements. The molding compound is UL 94 V-0 rated, and the device satisfies JESD201 Class 1A whisker resistance - confirming full environmental and process compliance for modern electronics manufacturing. These attributes are documented in Vishay's Material Category Policy (Doc. 99912) and apply to SMB10J6.5-E3/5B without exception.
