Product details
Overview
SMB10J6.5A-E3/5B 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 sensor interfaces and industrial I/O modules.
For engineers reviewing the SMB10J6.5A-E3/5B datasheet, SMB10J6.5A-E3/5B pinout, SMB10J6.5A-E3/5B application, or SMB10J6.5A-E3/5B equivalent, key selection criteria include clamping performance under 100 A surge, AEC-Q101 qualification status, RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a shunt-clamping device that remains high-impedance below VWM (6.5 V) and rapidly transitions to low-impedance conduction above VBR (min. 7.22 V) to limit transient overvoltages. Its glass-passivated junction ensures stable leakage (<500 µA at VWM) and robust surge handling across -55 °C to +150 °C junction temperature range.
Designed per ANSI/IEEE C62.35 standards, SMB10J6.5A-E3/5B delivers fast response time (<1 ns), low incremental surge resistance, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It is qualified to AEC-Q101 for automotive use and rated for non-repetitive 100 A IFSM surges.
Key Specifications

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Shunt-clamping TVS placed directly at connector or IC input pin to clamp transients before they reach sensitive analog front-ends. Use Value: Limits voltage to ≤11.2 V during 89.3 A surge, preventing latch-up or gate oxide damage in 5 V–12 V automotive ICs. | Use Scenario: Safeguarding digital input channels of programmable logic controllers against field-wiring induced surges in factory automation cabinets. IC Role / Device Role / Timing Role: Unidirectional TVS installed between field-side signal line and controller-side isolation barrier to absorb 1 kV/1 A transients. Use Value: Maintains <500 µA leakage at 6.5 V, avoiding false triggering of 24 V dry-contact inputs while clamping to safe levels. |
| DC Power Rail Protection | Consumer USB Port Protection |
Use Scenario: Secondary overvoltage protection on 5 V or 12 V DC power distribution networks feeding microcontrollers and memory in embedded systems. IC Role / Device Role / Timing Role: Parallel-connected TVS across VCC/GND to divert surge energy away from downstream regulators and LDOs. Use Value: Handles 1000 W peak pulse without degradation, sustaining system uptime during lightning-induced AC-line coupling events. | Use Scenario: ESD and surge suppression on USB 2.0 data lines (D+/D−) and VBUS in portable chargers and docking stations. IC Role / Device Role / Timing Role: Unidirectional TVS on VBUS line only (not data lines), providing primary overvoltage defense against hot-plug and adapter faults. Use Value: Clamps 10/1000 µs surges to 11.2 V while maintaining <500 µA leakage - compatible with USB BC1.2 charging detection circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A-E3/5B | Same SMB package, identical VWM/VBR/VC specs, but rated for 600 W PPPM (vs. 1000 W) | Limited to lower-energy surge environments; not suitable for automotive load-dump compliance | Select SMB10J6.5A-E3/5B where full 1000 W IEC 61000-4-5 Level 4 immunity is required |
| SACB6.5A | Same VWM/VBR, but SOD-123FL package (smaller footprint), 600 W PPPM, no AEC-Q101 qualification | Used in space-constrained consumer electronics; lacks automotive reliability validation | Choose SMB10J6.5A-E3/5B for production automotive or industrial designs requiring traceable qualification evidence |
Compared with SMBJ6.5A-E3/5B and SACB6.5A, SMB10J6.5A-E3/5B provides 67% higher peak pulse power and formal AEC-Q101 certification - critical for functional safety-critical nodes in ADAS sensors and engine control modules.

FAQ
What is the clamping voltage of SMB10J6.5A-E3/5B at its rated peak pulse current?
The SMB10J6.5A-E3/5B has a maximum clamping voltage (VC) of 11.2 V when subjected to its specified peak pulse current (IPPM) of 89.3 A using a 10/1000 µs waveform. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream circuitry. The SMB10J6.5A-E3/5B maintains this clamping performance across its operational temperature range.
Is SMB10J6.5A-E3/5B qualified for automotive applications?
Yes, SMB10J6.5A-E3/5B is AEC-Q101 qualified, as confirmed by Vishay's official documentation and ordering code suffix "HE3" variants. While the E3/5B variant itself is RoHS-compliant commercial grade, its base device SMB10J6.5A is fully qualified under AEC-Q101 - enabling drop-in use in automotive designs where qualification traceability is required. The SMB10J6.5A-E3/5B shares identical electrical and thermal characteristics with its HE3 counterpart.
What is the maximum reverse leakage current for SMB10J6.5A-E3/5B at its stand-off voltage?
The SMB10J6.5A-E3/5B exhibits a maximum reverse leakage current (ID) of 500 µA at its stand-off voltage (VWM) of 6.5 V, measured at 25 °C ambient. This low leakage supports energy-sensitive applications such as battery-backed systems and always-on sensor nodes. Leakage remains within specification across the full operating temperature range (-55 °C to +150 °C), verified per Vishay's thermal derating curves.
Does SMB10J6.5A-E3/5B have a defined polarity marking, and how is it identified?
Yes, SMB10J6.5A-E3/5B is a unidirectional TVS diode with polarity clearly marked by a cathode band on the SMB (DO-214AA) package body. The banded end corresponds to the cathode terminal, which must be connected toward the protected line (e.g., VBUS or signal), while the anode connects to ground. This marking complies with JEDEC DO-214AA mechanical standards and is visible under standard optical inspection.
What is the thermal resistance from junction to ambient for SMB10J6.5A-E3/5B, and how does it affect layout?
The typical junction-to-ambient thermal resistance (RθJA) of SMB10J6.5A-E3/5B is 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's datasheet; reducing pad area increases RθJA and risks thermal runaway during repeated surges. For reliable 1000 W pulse handling, designers must adhere strictly to the specified copper land pattern to maintain safe junction temperatures below 150 °C.
