Product details
Overview
SMB10J7.0-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 a 7.0 V stand-off voltage (VWM), 12.0 V maximum clamping voltage (VC) at 200 A peak pulse current (IPPM), and 1000 W peak pulse power (10/1000 µs waveform), making it suitable for automotive power supply input protection and industrial sensor interface circuits.
For engineers reviewing the SMB10J7.0-E3/5B datasheet, SMB10J7.0-E3/5B pinout, SMB10J7.0-E3/5B application, or SMB10J7.0-E3/5B equivalent, key selection criteria include clamping performance under 200 A surge, unidirectional polarity with cathode band marking, RoHS-compliant matte tin terminations, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its breakdown threshold (7.78–8.60 V at 10 mA), it avalanches to divert transient energy away from downstream ICs. Its low incremental surge resistance and fast response time (<1 ns) ensure effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
The device is rated for continuous operation from −55 °C to +150 °C junction temperature, with thermal resistance of 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable performance on standard 5.0 mm × 5.0 mm copper pads without forced cooling in most automotive and industrial PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum steady-state reverse voltage before significant leakage; sets operating margin above 5 V or 6.5 V nominal rails. |
| VBR min/max | 7.78 V / 8.60 V at 10 mA - Confirmed breakdown range ensures consistent turn-on across production lots. |
| VC @ IPPM | 12.0 V at 200 A (10/1000 µs) - Clamping voltage limits stress on protected 12 V tolerant devices during surge events. |
| PPPM | 1000 W - Peak pulse power rating defines maximum single-event energy absorption capability. |
| IFSM | 100 A (8.3 ms half-sine) - Surge current rating validates robustness against repetitive load-dump transients. |
| Junction temp. max | 150 °C - Enables use in under-hood automotive environments and high-temperature industrial enclosures. |
| Leakage @ VWM | 1000 µA max - Low leakage preserves efficiency in always-on power monitoring and sensor bias circuits. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode identified by color band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to ground or low-impedance return plane; must handle full 200 A surge current without trace fusing. |
| Cathode | Protected line connection / Clamping node | Connected to the line being protected (e.g., 12 V rail); voltage clamps to ≤12.0 V when surge exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics requiring long-term reliability under thermal cycling and vibration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A-E3/5B | Same VWM (7.0 V), identical DO-214AA package, but lower PPPM (600 W) and IPPM (100 A). | Not AEC-Q101 qualified; suitable for commercial-grade consumer or computing applications only. | Select when cost sensitivity outweighs automotive qualification and higher surge immunity. |
| 1.5SMC7.0A | Higher package thermal mass (DO-214AB), same VWM, but lower VC (10.5 V @ 100 A) and higher RθJA (60 °C/W). | Larger footprint; better clamping but less efficient heat dissipation in dense layouts. | Prefer where tighter clamping margin is critical and board space allows larger SMC package. |
Compared with SMB10J7.0-E3/5B, SMBJ7.0A-E3/5B offers lower surge handling and no automotive qualification, while 1.5SMC7.0A trades smaller size for improved clamping and reduced thermal resistance-making SMB10J7.0-E3/5B optimal for space-constrained AEC-Q101 designs needing 1000 W immunity.

The SMB10J7.0-E3/5B has a guaranteed breakdown voltage (VBR) range of 7.78 V to 8.60 V at 10 mA test current, measured per ANSI/IEEE C62.35 standards. This range ensures consistent avalanche initiation across temperature and manufacturing lot variations, directly supporting its 7.0 V stand-off voltage rating and enabling reliable protection of 5 V–7 V nominal circuits without false triggering.
Is SMB10J7.0-E3/5B suitable for automotive applications?
Yes, SMB10J7.0-E3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its −55 °C to +150 °C operating junction temperature range, MSL Level 1 reflow compatibility, and validation against mechanical shock, temperature cycling, and humidity testing confirm suitability for engine control modules, body control units, and ADAS power supplies where SMB10J7.0-E3/5B provides certified transient immunity.
What does the "E3/5B" suffix mean in SMB10J7.0-E3/5B?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance. The "5B" denotes packaging in 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel-optimized for high-volume automated SMT placement in production lines handling SMB10J7.0-E3/5B.
How does SMB10J7.0-E3/5B compare to bi-directional variants like SMB8J7.0CA?
SMB10J7.0-E3/5B is unidirectional with 1000 W peak pulse power and 200 A IPPM, whereas SMB8J7.0CA is bi-directional with 800 W and 400 A. The unidirectional SMB10J7.0-E3/5B offers superior power handling for DC rail protection, while SMB8J7.0CA supports AC-coupled or dual-polarity signal lines. SMB10J7.0-E3/5B also carries AEC-Q101 qualification; SMB8J7.0CA does not.
