Product details
Overview
SMBG10CA-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 a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the SMBG10CA-E3/5B datasheet, SMBG10CA-E3/5B pinout, SMBG10CA-E3/5B application, or SMBG10CA-E3/5B equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, bidirectional clamping behavior, thermal resistance (RθJA = 100 °C/W), and package-specific mounting guidance per J-STD-020 MSL Level 1.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, VC, and IPPM specifications in forward and reverse directions. Its glass-passivated junction ensures stable leakage (<5.0 μA at VWM) and fast response time (<1.0 ns), enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced transients (IEC 61000-4-5).
The device is rated for -55 °C to +150 °C operating junction temperature, supports 100 A non-repetitive surge current (8.3 ms half-sine, unidirectional only - not applicable here due to bidirectional configuration), and meets UL 497B recognition (QVGQ2) and RoHS compliance under suffix E3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse voltage before clamping begins; defines safe operating window for protected circuitry. |
| VBR (min/max) | 11.1 V / 12.3 V at 1 mA - Ensures reliable triggering above normal operating voltage while avoiding false trips. |
| VC @ IPPM | 17.0 V at 35.3 A - Limits transient voltage seen by downstream ICs to safe levels during 600 W surge events. |
| PPPM | 600 W - Peak pulse power handling capability with 10/1000 μs waveform; validates suitability for industrial surge standards. |
| ID @ VWM | ≤5.0 μA - Ultra-low leakage preserves signal integrity and battery life in high-impedance sensor paths. |
| TJ max. | +150 °C - Enables use in under-hood automotive and high-temperature industrial environments without derating. |
| MSL Level | Level 1 (J-STD-020) - Supports standard SMT reflow without moisture sensitivity concerns. |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, low-profile gull-wing lead frame with matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102. Bidirectional construction has no polarity marking; both terminals are electrically symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals serve identically as clamping nodes; no cathode band marking - enables flexible PCB layout in AC-coupled or differential lines. |
| Case (exposed pad) | Thermal and mechanical anchor | Non-electrical; provides mechanical stability and aids heat dissipation via copper pad thermal relief (0.2" × 0.2" recommended). |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping symmetry | Identical VBR, VC, and IPPM in both directions - eliminates need for orientation-aware placement in AC or differential signal protection. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress - suitable for engine control, ADAS sensor, and infotainment subsystems. |
| Glass passivated junction | Stable leakage and breakdown characteristics over lifetime and temperature - critical for long-term field reliability in industrial automation. |
| UL 497B recognition (QVGQ2) | Third-party safety certification for telecom and data line protectors - simplifies end-equipment regulatory approval. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients - enhances protection margin for sensitive 3.3 V or 5 V logic interfaces. |
Applications

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 | Same VWM/VBR/VC, but lower PPPM = 600 W (same rating), different package: SMB (DO-214AA); RθJA = 110 °C/W vs. 100 °C/W. | Less thermal margin in high-density layouts; not AEC-Q101 qualified. | Select SMBJ10CA only if legacy SMB footprint compatibility is required and automotive qualification is unnecessary. |
| SMCJ10CA | Higher PPPM = 1500 W, larger SMC (DO-214AB) package; VC = 17.0 V same, but IPPM = 88.2 A. | Overqualified for 600 W needs; occupies ~2.5× PCB area; higher parasitic inductance may affect ultrafast transients. | Choose SMCJ10CA only when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space permits larger footprint. |
Compared with SMBJ10CA and SMCJ10CA, SMBG10CA-E3/5B uniquely balances AEC-Q101 qualification, SMBG's optimized thermal performance (RθJA = 100 °C/W), and industry-standard 600 W surge rating in a compact, bidirectional, RoHS-compliant package - making it the preferred choice for next-generation automotive and industrial designs requiring certified reliability and layout efficiency.

FAQ
What is the clamping voltage of SMBG10CA-E3/5B at its rated peak pulse current?
The SMBG10CA-E3/5B has a maximum clamping voltage (VC) of 17.0 V at its peak pulse current (IPPM) of 35.3 A, measured with a 10/1000 μs waveform. This value is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88456 and defines the upper voltage limit imposed on protected circuitry during a 600 W transient event. The SMBG10CA-E3/5B maintains this clamping performance symmetrically in both directions due to its bidirectional design.
Is SMBG10CA-E3/5B qualified for automotive applications?
Yes, SMBG10CA-E3/5B is AEC-Q101 qualified, as explicitly stated in the Mechanical Data section and confirmed in the Notes on page 3 of Vishay document 88456. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD, validating its suitability for under-hood and cabin electronics. The "HE3" and "HM3" suffix variants are also AEC-Q101 qualified, but SMBG10CA-E3/5B carries the industrial-grade E3 suffix with full automotive reliability assurance.
Does SMBG10CA-E3/5B have polarity markings on the package?
No, SMBG10CA-E3/5B does not have polarity markings. As a bidirectional TVS diode, it exhibits identical electrical characteristics in both directions, and the SMBG (DO-215AA) package omits the cathode band used on unidirectional variants. This allows orientation-agnostic placement on PCBs - especially beneficial for differential signal lines like RS-485 or CAN, where symmetric protection is required without routing constraints. The absence of marking is specified in the Polarity note on page 1 of the datasheet.
What is the thermal resistance of SMBG10CA-E3/5B, and how does it impact layout?
The SMBG10CA-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as listed in the Thermal Characteristics table on page 3. This value is 10 °C/W better than the SMBJ variant, enabling higher sustained surge duty cycles or operation in elevated ambient temperatures. Layout must follow the recommended pad dimensions and avoid excessive solder mask coverage on thermal pads to maintain this rating.
Can SMBG10CA-E3/5B be used in place of a unidirectional TVS like SMBG10A?
No - SMBG10CA-E3/5B is strictly bidirectional and cannot replace unidirectional types such as SMBG10A in circuits requiring DC blocking or polarity-sensitive clamping (e.g., single-supply power rail protection). While both share VWM = 10 V and similar VBR, SMBG10A conducts only in reverse bias and has a forward voltage drop (~3.5 V at 50 A), whereas SMBG10CA-E3/5B clamps equally in both directions with no forward conduction path. Substitution would compromise circuit functionality in DC-biased applications.
