Product details
Overview
SMCG10CA-M3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for clamping ESD and surge transients on signal/power lines. 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 (10/1000 µs), 88.2 A peak pulse current (IPPM), and 17.0 V maximum clamping voltage (VC) - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMCG10CA-M3/57T datasheet, SMCG10CA-M3/57T pinout, SMCG10CA-M3/57T application, or SMCG10CA-M3/57T equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, halogen-free RoHS compliance, DO-215AB mechanical data, and real-world protection use cases - all aligned to Vishay's 88457 document revision 09-Jan-2024.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max (11.1–12.3 V), ID ≤ 5.0 µA at VWM, and VC = 17.0 V at IPPM = 88.2 A under 10/1000 µs waveform. Its glass-passivated junction ensures stable clamping performance and low incremental surge resistance.
Rated for TJ = –55 °C to +150 °C, it meets MSL Level 1 per J-STD-020 (260 °C peak reflow), supports automated SMT placement, and is qualified to AEC-Q101 - confirming suitability for automotive-grade transient suppression without derating in harsh thermal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping initiates; defines safe signal line bias margin. |
| VBR (min/max) | 11.1 V / 12.3 V at IT = 1 mA - precise breakdown threshold ensuring predictable turn-on during overvoltage events. |
| VC @ IPPM | 17.0 V at IPPM = 88.2 A - clamping voltage limits downstream IC stress during 10/1000 µs surges. |
| PPPM | 1500 W - peak transient energy absorption capacity under standardized surge waveform. |
| ID @ VWM | ≤ 5.0 µA - ultra-low leakage preserves signal integrity and battery life in always-on circuits. |
| TJ max | +150 °C - enables operation in engine bay, powertrain, and industrial control enclosures. |
| Package | SMCG (DO-215AB) - low-profile SMD outline with 0.220–0.245" body length, optimized for high-density PCB layouts. |
Pinout & Package
SMCG10CA-M3/57T uses the DO-215AB (SMCG) surface-mount package: bidirectional construction with no polarity marking; symmetrical terminals accept voltage transients from either direction. Package dimensions: 6.22 × 5.59 × 2.41 mm (L × W × H), matte tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Identical terminal behavior in both directions; no cathode band marking required. |
| Terminal 2 | Anode/Cathode (bidirectional) | Electrically interchangeable with Terminal 1; forms symmetrical clamping path across protected line. |
Key Features
| Feature | Design Value |

Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive switching transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bidirectional clamping device placed directly at connector entry point to shunt surge energy before reaching ASIC or MCU input pins. Use Value: Limits transient voltage to ≤17.0 V, preventing latch-up or gate oxide damage in automotive-grade microcontrollers rated for 18 V absolute max. |
Use Scenario: Safeguarding RS-485/RS-232 communication lines and analog input channels in PLC modules exposed to EFT and lightning-induced surges. IC Role / Device Role / Timing Role: Fast-response (sub-nanosecond) TVS placed across differential pairs or single-ended signal lines to clamp ±1 kV ESD per IEC 61000-4-2. Use Value: Maintains signal fidelity with <5.0 µA leakage at 10 V, avoiding DC offset errors in 16-bit ADC front-ends. |
| Consumer Power Adapter Input | Telecom Line Card Protection |
Use Scenario: Secondary-side transient suppression on 5 V/9 V USB-C PD adapter outputs against hot-plug and cable discharge events. IC Role / Device Role / Timing Role: Standoff-rated TVS mounted between VBUS and GND to absorb repetitive 30 A/10/1000 µs surges without degradation. Use Value: Delivers 1500 W peak power handling in 6.22 mm × 5.59 mm footprint - enabling compact, cost-effective overvoltage hardening. |
Use Scenario: Primary protection for Ethernet PHYs and DSL line drivers subjected to induced surges from nearby AC mains or antenna coupling. IC Role / Device Role / Timing Role: First-stage clamping element upstream of polymeric PTC and secondary TVS, defining system-level surge immunity per GR-1089-CORE. Use Value: With 17.0 V clamping and 88.2 A IPPM, it reduces let-through energy by >85% versus unprotected traces, extending downstream component lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V) and VC (17.0 V), but lower PPPM (400 W) and smaller SMA package (DO-214AC); RθJA = 110 °C/W vs. 75 °C/W. | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or high-repetition EFT. | Select SMAJ10CA only for space-constrained consumer designs where 400 W surge rating suffices. |
| SMCJ10CA | Same DO-214AB package footprint but higher PPPM (1500 W), identical VWM/VC, and AEC-Q101 qualification; differs in thermal resistance (RθJA = 65 °C/W). | Better thermal performance allows sustained operation at higher ambient temperatures (>125 °C). | Choose SMCJ10CA when board layout permits larger 7.11 mm × 6.22 mm footprint and extended thermal margin is critical. |
Compared with SMAJ10CA and SMCJ10CA, SMCG10CA-M3/57T offers identical 1500 W surge rating and AEC-Q101 qualification in a more compact DO-215AB outline (6.22 mm × 5.59 mm), delivering superior power density and compatibility with fine-pitch automotive PCB assemblies.

FAQ
What is the clamping voltage of SMCG10CA-M3/57T at its rated peak pulse current?
The SMCG10CA-M3/57T has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current (IPPM) of 88.2 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay document 88457, ensuring predictable overvoltage limiting for downstream ICs. The SMCG10CA-M3/57T maintains this clamping performance across its full operating temperature range.
Is SMCG10CA-M3/57T suitable for automotive applications?
Yes, SMCG10CA-M3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its –55 °C to +150 °C operating range, MSL Level 1 reflow compatibility, and bidirectional surge handling meet stringent automotive reliability requirements. The SMCG10CA-M3/57T is referenced in Vishay's automotive-grade product documentation and used in production vehicle platforms.
What does the "M3" suffix indicate in SMCG10CA-M3/57T?
"M3" denotes halogen-free, RoHS-compliant construction meeting JEDEC J-STD-20D and IEC 61249-2-21 standards, with matte tin-plated leads qualified per J-STD-002. It distinguishes SMCG10CA-M3/57T from E3 (standard RoHS) and HM3 (AEC-Q101 + halogen-free) variants. The SMCG10CA-M3/57T retains full electrical specifications and AEC-Q101 qualification while fulfilling green manufacturing mandates.
How does SMCG10CA-M3/57T differ from unidirectional SMCG10A-M3/57T?
SMCG10CA-M3/57T is bidirectional with symmetrical clamping in both polarities and no cathode marking, whereas SMCG10A-M3/57T is unidirectional with a cathode band and conducts only in reverse bias. Their VWM (10 V), VBR (11.1–12.3 V), and VC (17.0 V) match, but SMCG10A-M3/57T supports forward surge current (IFSM = 200 A) - a capability irrelevant to SMCG10CA-M3/57T due to its bidirectional architecture.
What is the thermal resistance of SMCG10CA-M3/57T?
The SMCG10CA-M3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal, and a junction-to-lead resistance (RθJL) of 15 °C/W. These values are specified in Vishay document 88457 and enable accurate thermal modeling for PCB layout - especially critical in sealed automotive enclosures where ambient temperatures exceed 100 °C. The SMCG10CA-M3/57T's thermal performance supports continuous operation up to TJ = +150 °C.
