Product details
Overview
SMBG8.0CA-E3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of signal and power lines. It features 8.0 V stand-off voltage (VWM), 13.6 V maximum clamping voltage (VC) at 44.1 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform), making it suitable for automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the SMBG8.0CA-E3/5B datasheet, SMBG8.0CA-E3/5B pinout, SMBG8.0CA-E3/5B application, or SMBG8.0CA-E3/5B equivalent, key selection criteria include bidirectional clamping symmetry, low VC/VWM ratio (1.7×), AEC-Q101 qualification, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with breakdown voltage (VBR) specified at 8.89–9.83 V (IT = 1 mA), matching its 8.0 V stand-off rating. Its clamping response is validated under standardized 10/1000 μs surge waveforms, delivering consistent VC ≤ 13.6 V up to IPPM = 44.1 A.
Thermal performance is defined by RθJA = 100 °C/W (on 0.2" × 0.2" pads) and TJ(max) = +150 °C, supporting operation in under-hood automotive environments. The device meets J-STD-020 MSL Level 1 and passes JESD201 Class 2 whisker testing, confirming reliability for high-volume industrial assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous reverse working voltage before clamping initiates |
| VBR (min/max) | 8.89 V / 9.83 V at IT = 1 mA - Ensures tight breakdown tolerance for predictable turn-on |
| VC @ IPPM | 13.6 V at 44.1 A - Low clamping voltage limits stress on downstream ICs during transients |
| PPPM | 600 W (10/1000 μs) - Supports repetitive surge events at 0.01% duty cycle without degradation |
| IPPM | 44.1 A - Peak surge current handling capability verified per Fig. 1 and Table on p.2 |
| TJ(max) | +150 °C - Enables use in high-temperature automotive and industrial enclosures |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., temperature, pressure) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt transients before reaching signal conditioning circuitry. Use Value: Clamps 13.6 V max at 44.1 A, maintaining safe voltage levels for 5 V tolerant transceivers and ADC front-ends while surviving repeated 12 V system surges. |
Use Scenario: Safeguarding digital input/output channels on programmable logic controllers exposed to inductive switching noise from solenoids and relays. IC Role / Device Role / Timing Role: Fast-response TVS across channel-to-ground to absorb 600 W surge energy without latch-up or failure. Use Value: 100 °C/W thermal resistance enables stable operation on PCBs with minimal copper area, reducing board space vs. larger DO-214 packages. |
| Consumer USB Port Protection | Telecom Line Interface Protection |
Use Scenario: Shielding USB 2.0 data lines (D+/D−) from ESD events (>±15 kV contact) in set-top boxes and smart home hubs. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp placed inline with differential pair to suppress common-mode transients. Use Value: Symmetric clamping ensures equal protection on both lines; 1.0 μA leakage at 8.0 V preserves signal integrity and minimizes standby current drain. |
Use Scenario: Guarding Ethernet PHY interfaces and analog telephone line drivers against lightning-induced surges in VoIP gateways and DSL modems. IC Role / Device Role / Timing Role: Primary-level surge suppressor mounted at RJ-11/RJ-45 jack to divert energy before reaching isolation transformers. Use Value: 600 W rating exceeds IEC 61000-4-5 Level 4 (4 kV line-earth), providing margin for field-deployed telecom equipment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA | Same VWM (8.0 V), higher PPPM = 600 W but lower IPPM = 43.4 A; SMB (DO-214AA) package, 1.6 mm taller | Less compact footprint; slightly higher clamping VC = 13.6 V same, but thermal resistance differs due to package geometry | Select SMBJ8.0CA only if existing layout accommodates taller SMB package and requires legacy footprint compatibility |
| SMCJ8.0CA | Same VWM and VC, but PPPM = 1500 W and IPPM = 109 A; larger SMC (DO-214AB) package, 2× PCB area | Over-specified for most 600 W applications; used where extreme surge margin or higher single-pulse survivability is mandated | Choose SMCJ8.0CA only when system-level testing demands >1000 W surge handling or extended lifetime under frequent transients |
Compared with SMBJ8.0CA and SMCJ8.0CA, SMBG8.0CA-E3/5B delivers identical electrical protection performance in the smallest possible footprint (SMBG), enabling higher board density and lower assembly cost for space-constrained automotive and industrial modules.

FAQ
What is the clamping voltage of SMBG8.0CA-E3/5B at its rated peak pulse current?
The SMBG8.0CA-E3/5B has a maximum clamping voltage (VC) of 13.6 V when subjected to its rated peak pulse current (IPPM) of 44.1 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 and Table on page 2 of Vishay document 88456 and defines the upper voltage limit imposed on protected circuits during surge events. The SMBG8.0CA-E3/5B maintains this clamping performance bidirectionally.
Is SMBG8.0CA-E3/5B suitable for automotive applications?
Yes, SMBG8.0CA-E3/5B is AEC-Q101 qualified, confirming its reliability for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces. Its operating junction temperature range of –55 °C to +150 °C, MSL Level 1 rating, and glass-passivated junction meet stringent automotive environmental and assembly requirements. The SMBG8.0CA-E3/5B is explicitly listed in Vishay's AEC-Q101 qualified product table.
How does the SMBG8.0CA-E3/5B differ from unidirectional variants like SMBG8.0A-E3/5B?
The SMBG8.0CA-E3/5B is bidirectional, meaning it provides symmetrical clamping in both polarities with no cathode marking, whereas SMBG8.0A-E3/5B is unidirectional and features a cathode band. Electrically, SMBG8.0CA-E3/5B has identical VWM (8.0 V) and VC (13.6 V) but supports surge suppression on AC-coupled or differential lines where polarity reversal occurs. The SMBG8.0CA-E3/5B replaces two unidirectional devices in such topologies.
What is the maximum reverse leakage current for SMBG8.0CA-E3/5B at its stand-off voltage?
The SMBG8.0CA-E3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA at its stand-off voltage (VWM) of 8.0 V, measured at TA = 25 °C. This low leakage ensures minimal power loss and signal distortion in always-on interfaces such as automotive LIN bus or industrial 4–20 mA loops. The SMBG8.0CA-E3/5B maintains this specification across its full operating temperature range per Vishay's Electrical Characteristics table.
What packaging format does SMBG8.0CA-E3/5B ship in?
SMBG8.0CA-E3/5B ships in 13-inch diameter plastic tape and reel packaging, with a base quantity of 3200 units per reel (ordering code suffix "5B"). This format is optimized for high-speed pick-and-place assembly and complies with EIA-481 standards. The "E3" suffix indicates RoHS-compliant, industrial-grade construction with matte tin-plated leads meeting J-STD-002 solderability requirements. The SMBG8.0CA-E3/5B reel is compatible with standard SMT feeders.
