Product details
Overview
SMB10J10A-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 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 17.0 V clamping voltage (VC) at 5.0 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs, industrial sensor interfaces, and power supply input stages.
For engineers reviewing the SMB10J10A-E3/5B datasheet, SMB10J10A-E3/5B pinout, SMB10J10A-E3/5B application, or SMB10J10A-E3/5B equivalent, key selection criteria include clamping performance under 10/1000 µs surges, AEC-Q101 qualification status, unidirectional polarity marking, thermal resistance (RθJA = 72 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (11.1–12.3 V), it avalanches to limit transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable breakdown and low leakage (<5.0 µA at VWM), while MSL Level 1 moisture sensitivity supports lead-free reflow up to 260 °C.
The device delivers 1000 W peak pulse power handling with low incremental surge resistance and fast response time (<1 ns), enabling robust protection against ISO 7637-2 load dump and IEC 61000-4-5 surges. Its unidirectional configuration includes cathode band marking and is rated for TJ = -55 to +150 °C operation.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-E3/5B | Same VWM (10 V), identical SMB package, but lower PPPM (600 W vs. 1000 W) | Not suitable for high-energy automotive load dump; limited to consumer-grade 100–200 W surge environments | Select SMB10J10A-E3/5B where 1000 W surge immunity is required per ISO 7637-2 Pulse 5a. |
| SMAJ10A-E3/5B | Same VWM and VBR range, but SMA (DO-214AC) package with higher RθJA (110 °C/W) and lower PPPM (400 W) | Limited thermal performance and power handling; unsuitable for sustained surge duty cycles | Choose SMB10J10A-E3/5B for improved thermal dissipation and higher surge margin in space-constrained layouts. |

FAQ
What is the clamping voltage of SMB10J10A-E3/5B at its rated peak pulse current?
The SMB10J10A-E3/5B has a maximum clamping voltage (VC) of 17.0 V at 5.0 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuitry during surge events. The SMB10J10A-E3/5B maintains this clamping performance across its qualified operating temperature range.
Is SMB10J10A-E3/5B qualified for automotive applications?
Yes, SMB10J10A-E3/5B is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per automotive reliability standards. Its RoHS-compliant E3 suffix and MSL Level 1 rating further support use in automotive ECUs, body control modules, and ADAS sensor units. The SMB10J10A-E3/5B meets requirements for under-hood and cabin-mounted electronics.
What is the standoff voltage and breakdown voltage range for SMB10J10A-E3/5B?
The SMB10J10A-E3/5B has a maximum working peak reverse voltage (VWM) of 10 V and a breakdown voltage (VBR) range of 11.1 V to 12.3 V at 1.0 mA test current. This 1.1 V margin between VWM and minimum VBR ensures reliable blocking during normal operation while guaranteeing fast avalanche initiation during transients. The SMB10J10A-E3/5B datasheet specifies these values at TA = 25 °C with derating above that temperature.
How does the SMB10J10A-E3/5B package compare to SMA and SMC variants in thermal performance?
The SMB10J10A-E3/5B uses the SMB (DO-214AA) package with typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W - significantly lower than SMA (DO-214AC, ~110 °C/W) and higher than SMC (DO-214AB, ~40 °C/W). This makes the SMB10J10A-E3/5B a balanced choice for medium-power surge protection where board space is constrained but thermal headroom exceeds SMA limits. Its RθJL of 20 °C/W further supports localized heat sinking via PCB copper.
Can SMB10J10A-E3/5B be used in bidirectional configurations?
No, SMB10J10A-E3/5B is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. Bidirectional variants in the same family carry the "CA" suffix (e.g., SMB8J10CA). Using SMB10J10A-E3/5B in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect. For symmetric surge protection, select an explicitly bidirectional part - the SMB10J10A-E3/5B is not rated for reverse conduction.
