Product details
Overview
SMB8J10CA-E3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on signal and power lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V clamping voltage (VC) at 47.1 A peak pulse current (IPPM), and 800 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB8J10CA-E3/5B datasheet, SMB8J10CA-E3/5B pinout, SMB8J10CA-E3/5B application, or SMB8J10CA-E3/5B equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low leakage (<1 µA at VWM), RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal bias it presents <1 µA reverse leakage at 10 V, then rapidly avalanches when transients exceed VBR (11.1–12.3 V), limiting downstream voltage to ≤17.0 V at 47.1 A. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Rated for -55 °C to +150 °C junction temperature, it meets MSL Level 1 per J-STD-020 (260 °C peak reflow), supports 8.3 ms half-sine surge withstand up to 100 A (IFSM), and delivers thermal resistance of 20 °C/W (junction-to-lead) for reliable power dissipation in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before significant conduction begins |
| VBR (min/max) | 11.1 V / 12.3 V at 1 mA - precise avalanche onset range ensuring predictable turn-on during transients |
| VC @ IPPM | 17.0 V at 47.1 A - clamped voltage level protecting downstream ICs rated for ≤16 V logic rails |
| PPPM | 800 W (10/1000 µs) - energy-handling capacity sufficient for ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 3 surges |
| ID @ VWM | <1 µA - negligible standby power loss and signal integrity impact in high-impedance sensor lines |
| TJ max. | +150 °C - enables operation in under-hood automotive environments and sealed industrial enclosures |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking; symmetrical two-terminal construction with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Both terminals function identically; conducts bidirectionally when voltage exceeds ±VBR - no orientation required during placement |
| Case (body) | Thermal and mechanical interface | Plastic body provides UL 94 V-0 flammability rating; thermal path to PCB copper via soldered leads (RθJL = 20 °C/W) |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Protects AC-coupled and differential signal lines (e.g., CAN, RS-485) without polarity constraints |
| AEC-Q101 qualification | Validated for automotive electronics including engine control modules, ADAS sensors, and body controllers |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on protected ICs - critical for 3.3 V/5 V microcontrollers and transceivers |
| MSL Level 1 rating | Enables standard reflow assembly without moisture sensitivity concerns or baking requirements |
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA-E3/5B | Unidirectional variant with same VWM/VBR/VC but asymmetric conduction - requires correct polarity orientation | Suitable only for DC-biased lines where polarity is fixed; not usable on AC or differential signals | Select SMBJ10CA-E3/5B only when protecting unidirectional 10 V supply rails or single-ended logic lines |
| SMAJ10CA-E3/52 | Same electrical specs but in smaller SMA (DO-214AC) package - 30% lower PPPM (400 W) and higher RθJA (100 °C/W) | Limited to lower-energy transients and less thermally demanding environments due to reduced power handling | Choose SMAJ10CA-E3/52 only for space-constrained consumer boards with <400 W surge exposure and ambient <85 °C |
Compared with SMBJ10CA-E3/5B and SMAJ10CA-E3/52, SMB8J10CA-E3/5B uniquely combines bidirectional symmetry, 800 W surge capacity, and AEC-Q101 qualification - making it the only option qualified for automotive signal-line protection without polarity constraints or derating.

FAQ
What is the clamping voltage of SMB8J10CA-E3/5B at its rated peak pulse current?
The SMB8J10CA-E3/5B clamps to a maximum of 17.0 V when subjected to its specified peak pulse current of 47.1 A (10/1000 µs waveform). This VC value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring compatibility with 16 V-tolerant IC inputs.
Is SMB8J10CA-E3/5B suitable for automotive applications?
Yes, SMB8J10CA-E3/5B is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junctions, MSL Level 1 reflow compatibility, and validation across temperature cycling, high-temperature reverse bias, and ESD tests - making it appropriate for engine control units, ADAS camera modules, and body electronics where reliability under vibration and thermal stress is mandatory.
Does SMB8J10CA-E3/5B have polarity markings?
No, SMB8J10CA-E3/5B is a bidirectional TVS diode and carries no polarity marking on its SMB (DO-214AA) package. Its symmetrical terminal structure allows unrestricted orientation during PCB placement - simplifying layout and eliminating risk of reverse installation in differential or AC-coupled signal paths.
What is the maximum operating temperature for SMB8J10CA-E3/5B?
The SMB8J10CA-E3/5B has a maximum junction temperature (TJ max.) of +150 °C and an operating junction/storage temperature range of -55 °C to +150 °C. This wide range supports deployment in under-hood automotive locations, industrial motor drives, and outdoor telecom equipment without thermal derating in most standard PCB layouts with recommended 5.0 mm × 5.0 mm copper pads.
How does SMB8J10CA-E3/5B differ from SMBJ10CA-E3/5B?
SMB8J10CA-E3/5B is bidirectional with symmetrical clamping, while SMBJ10CA-E3/5B is unidirectional and requires cathode alignment. Both share identical VWM (10 V), VBR (11.1–12.3 V), and VC (17.0 V), but SMB8J10CA-E3/5B supports AC signal protection without polarity constraints - essential for CAN, RS-485, and USB differential pairs where SMBJ10CA-E3/5B cannot be substituted without redesign.
