Product details
Overview
SMCG10CA-E3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (PPPM), and clamps to ≤17.0 V at 88.2 A (10/1000 µs waveform), making it suitable for automotive sensor line and industrial I/O port protection.
For engineers reviewing the SMCG10CA-E3/9AT datasheet, SMCG10CA-E3/9AT pinout, SMCG10CA-E3/9AT application, or SMCG10CA-E3/9AT equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, MSL Level 1 rating, 1500 W surge handling, and DO-215AB thermal performance with RθJA = 75 °C/W.
Technical Context
This TVS operates symmetrically in both directions due to its bidirectional construction, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 µA at VWM), while the low incremental surge resistance supports fast clamping response under high-di/dt events.
The device is rated for TJ = –55 °C to +150 °C and meets UL 497B recognition (QVGQ2) for telecom and industrial protectors. Its 13" tape-and-reel packaging (9AT) supports automated SMT placement, and the matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications

Applications
| Automotive Sensor Protection | Industrial I/O Port Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS placed at connector interface to clamp ±100 V transients before reaching signal conditioning circuitry. Use Value: Limits clamped voltage to ≤17.0 V, ensuring downstream op-amps and ADCs remain within absolute maximum ratings during 1500 W surges. | Use Scenario: Safeguarding PLC digital input modules against field-wiring induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC input channels, mounted directly at terminal block entry point. Use Value: Withstands 88.2 A peak pulse current (10/1000 µs), preventing latch-up or permanent damage to optocouplers and microcontrollers. |
| Telecom Line Interface | Consumer Device USB/Display Port |
Use Scenario: Shielding Ethernet PHYs and PoE injectors from lightning-induced surges on twisted-pair lines. IC Role / Device Role / Timing Role: Secondary-level protector after gas discharge tube (GDT), absorbing residual energy with sub-100 ns response. Use Value: Low clamping voltage (≤17.0 V) prevents overstress on 3.3 V or 5 V PHY supply rails during multi-kV surge events. | Use Scenario: Protecting high-speed data lanes (e.g., USB 2.0, eDP) in laptops and tablets from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. <50 pF) placed adjacent to connector to minimize signal integrity impact. Use Value: Bidirectional symmetry avoids signal inversion risk on differential pairs; AEC-Q101 grade supports extended product lifecycle validation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V), lower PPPM (400 W), SMA package (DO-214AC), higher RθJA (~110 °C/W) | Lower surge capacity; suited for consumer-grade, non-automotive applications with less stringent pulse requirements | Select SMAJ10CA only when board space constraints favor SMA or surge energy is limited to <400 W |
| 1.5KE10CA | Same VWM (10 V), higher PPPM (1500 W), axial-leaded DO-15 package, slower thermal response | Not surface-mountable; requires through-hole assembly and larger PCB real estate; unsuitable for automated SMT lines | Choose 1.5KE10CA only for legacy through-hole designs where rework flexibility outweighs SMT efficiency |
Compared with SMAJ10CA and 1.5KE10CA, the SMCG10CA-E3/9AT delivers identical 10 V standoff and 1500 W surge rating in a compact, AEC-Q101-qualified DO-215AB package optimized for automotive and industrial SMT production-without requiring layout changes or derating for thermal performance.

FAQ
What is the clamping voltage of the SMCG10CA-E3/9AT under maximum rated surge current?
The SMCG10CA-E3/9AT clamps to a maximum of 17.0 V when subjected to its peak pulse current (IPPM) of 88.2 A under the standardized 10/1000 µs waveform. This value is measured at the device terminals with the specified 0.31" × 0.31" copper pad layout and confirms its ability to limit voltage stress on downstream 3.3 V or 5 V logic circuits during surge events. The SMCG10CA-E3/9AT maintains this clamping performance across its full operating temperature range.
Is the SMCG10CA-E3/9AT suitable for automotive applications?
Yes, the SMCG10CA-E3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, ADAS sensor interfaces, and body electronics. Its bidirectional architecture, 1500 W surge rating, and operation up to +150 °C junction temperature meet critical requirements for ISO 7637-2 and ISO 16750-2 compliance testing. The SMCG10CA-E3/9AT also carries UL 497B recognition for telecom-grade protection in vehicle networks.
Does the SMCG10CA-E3/9AT have polarity markings on the package?
No, the SMCG10CA-E3/9AT does not feature polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., SMCG10A), which use a cathode band to indicate polarity, the CA-suffix devices operate identically in both directions-eliminating the need for orientation-dependent placement. This simplifies PCB layout and reduces assembly errors in differential or floating signal paths protected by the SMCG10CA-E3/9AT.
What is the thermal resistance of the SMCG10CA-E3/9AT, and how does it affect layout?
The SMCG10CA-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes no additional heatsinking and defines the baseline for thermal derating above 25 °C ambient. To maintain reliability, PCB layout must allocate sufficient copper area per terminal and avoid excessive trace length or narrow connections that increase thermal impedance. The SMCG10CA-E3/9AT's low RθJA enables effective self-cooling in compact industrial modules.
How does the SMCG10CA-E3/9AT differ from the unidirectional SMCG10A variant?
The SMCG10CA-E3/9AT is bidirectional with symmetrical clamping in both polarities and no cathode marking, whereas the SMCG10A is unidirectional with a defined cathode band and conducts forward surge current only in one direction (IFSM = 200 A). Their VWM (10 V) and PPPM (1500 W) are identical, but the SMCG10A supports higher forward surge capability and is used where polarity is fixed-e.g., DC power rail protection. The SMCG10CA-E3/9AT is preferred for AC signals, differential buses, or floating grounds where polarity reversal may occur.
