Product details
Overview
SMCG100CA-M3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) in the SMCG (DO-215AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamps to ≤162 V at 9.3 A IPPM under 10/1000 µs waveform - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMCG100CA-M3/57T datasheet, SMCG100CA-M3/57T pinout, SMCG100CA-M3/57T application, or SMCG100CA-M3/57T equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), bidirectional clamping behavior, and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker testing.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping transients above ±111 V in both polarities with sub-nanosecond response. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling consistent clamping performance across temperature (−55 °C to +150 °C).
Designed for surface-mount automated placement, it uses matte tin-plated leads solderable per J-STD-002 and JESD22-B102, mounted on 8.0 mm × 8.0 mm copper pads. The SMCG (DO-215AB) case meets UL 94 V-0 and MSL Level 1 (260 °C peak reflow), supporting high-reliability automotive and industrial deployments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100CA | Same VWM (100 V) and PPPM (400 W), but lower power rating and DO-214AC (SMA) package | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 1500 W surge margin |
| SMCJ100CA | Identical VWM (100 V), higher PPPM (1500 W), same DO-214AB (SMC) footprint but larger than SMCG | Requires PCB area increase (~25% larger); shares thermal profile but lacks M3 halogen-free designation | Choose if existing SMC footprint is locked and halogen-free requirement is secondary |
Compared with SMAJ100CA and SMCJ100CA, SMCG100CA-M3/57T uniquely combines AEC-Q101 qualification, halogen-free construction, and compact DO-215AB packaging - enabling automotive-grade protection in space-constrained layouts without sacrificing surge robustness or regulatory compliance.

FAQ
What does the "CA" suffix indicate in SMCG100CA-M3/57T?
The "CA" suffix denotes a bidirectional configuration: SMCG100CA-M3/57T clamps transients symmetrically in both polarities, making it suitable for AC-coupled or floating signal paths. Unlike unidirectional variants (e.g., SMCG100A), it has no cathode marking and exhibits matched VBR min/max values (111 V / 123 V) in either direction - confirmed in Vishay's Electrical Characteristics table on page 2 of document 88457.
Is SMCG100CA-M3/57T qualified for automotive applications?
Yes, SMCG100CA-M3/57T is AEC-Q101 qualified, as explicitly stated in the Mechanical Data section and noted in the Ratings and Characteristics Curves table (footnote 1). This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge - validating its use in automotive powertrain, body electronics, and ADAS subsystems per industry reliability standards.
What is the meaning of the "M3" suffix in SMCG100CA-M3/57T?
The "M3" suffix indicates halogen-free, RoHS-compliant construction with matte tin-plated leads that meet JESD201 Class 2 whisker resistance requirements. Per Vishay's ordering information table, M3 parts are industrial-grade and distinct from HE3/HM3 (AEC-Q101 qualified) and E3 (standard RoHS). SMCG100CA-M3/57T therefore satisfies environmental compliance without automotive qualification - appropriate for industrial and telecom applications demanding green materials.
How is the clamping voltage VC of SMCG100CA-M3/57T determined, and what does 162 V represent?
The clamping voltage VC = 162 V is measured at the peak pulse current IPPM = 9.3 A under a standardized 10/1000 µs double-exponential surge waveform, as defined in ANSI/IEEE C62.35. This value represents the maximum voltage imposed on protected circuitry during worst-case transient events - a critical design parameter for ensuring downstream ICs remain within absolute maximum ratings. It is specified in the Electrical Characteristics table for SMCG100A/CA on page 2 of document 88457.
Can SMCG100CA-M3/57T be used in place of a unidirectional TVS like SMCG100A?
No - SMCG100CA-M3/57T is strictly bidirectional and lacks polarity marking, while SMCG100A is unidirectional with a cathode band. Substituting them requires circuit redesign: SMCG100A conducts only during positive surges relative to cathode, whereas SMCG100CA-M3/57T clamps equally on both polarities. Using SMCG100CA-M3/57T in a unidirectional rail may cause unintended conduction during normal negative excursions, risking malfunction. Always match device polarity to system topology.
