Product details
Overview
SMCG5.0CA-M3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) in the SMCG (DO-215AB) package, designed for robust overvoltage protection on signal and power lines. It features a 5.0 V stand-off voltage (VWM), 6.40–7.25 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamps to ≤9.20 V at 163 A IPPM under 10/1000 µs surge - ideal for safeguarding automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMCG5.0CA-M3/57T datasheet, SMCG5.0CA-M3/57T pinout, SMCG5.0CA-M3/57T application, or SMCG5.0CA-M3/57T equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, halogen-free RoHS compliance (M3 suffix), 150 °C junction rating, and DO-215AB thermal performance with RθJA = 75 °C/W.
Technical Context
This device operates as a voltage-clamped shunt protector, responding within picoseconds to transients exceeding its VWM. Its glass-passivated junction ensures stable VBR tolerance (±5% typical) and low incremental surge resistance, enabling consistent clamping across repetitive 10/1000 µs surges up to 1500 W.
Rated for -55 °C to +150 °C operation and qualified to AEC-Q101, the SMCG5.0CA-M3/57T supports automotive-grade reliability without derating below 25 °C. Its bidirectional structure eliminates polarity concerns in AC-coupled or differential signal paths, and its M3 suffix confirms halogen-free molding compound and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 6.40 V / 7.25 V at 10 mA - tight breakdown window ensures predictable turn-on threshold |
| VC @ IPPM | ≤9.20 V at 163 A - low clamping voltage protects downstream 5 V logic and analog circuitry |
| PPPM | 1500 W - handles high-energy transients per ISO 7637-2 Pulse 1/2a/5a in automotive environments |
| ID @ VWM | 1000 µA - low leakage preserves signal integrity in high-impedance sensor inputs |
| TJ max | +150 °C - enables placement near heat sources in engine control units and power modules |
| Package | SMCG (DO-215AB) - surface-mount gull-wing footprint with 8.0 mm × 8.0 mm copper pad thermal relief |
Pinout & Package
SMCG5.0CA-M3/57T uses the SMCG (DO-215AB) package: a bidirectional, unmarked, two-terminal SMD device with gull-wing leads. No polarity marking is present, as both terminals are symmetrical for AC transient suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity - no DC bias dependency |
| Terminal 2 | Anode/Cathode (bidirectional) | Electrically identical to Terminal 1; forms symmetric clamping path across protected line pair |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including powertrain, body electronics, and ADAS sensor interfaces |
| Halogen-free & RoHS compliant (M3) | Meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability for harsh-environment PCBs |
| Low RθJA = 75 °C/W | Enables reliable 6.5 W power dissipation on standard 8 mm × 8 mm copper pads without heatsinking |
| Fast response time & low surge resistance | Clamps sub-nanosecond transients with minimal overshoot, preserving signal fidelity in high-speed data lines |
| Bidirectional symmetry | Identical VBR and VC in both directions - eliminates need for orientation-aware layout or external diodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-M3/57T | Unidirectional; same VWM/VBR/PPPM but lacks bidirectional symmetry and AEC-Q101 qualification | Requires correct polarity placement; unsuitable for AC-coupled or floating differential lines | Select only when polarity is fixed and automotive qualification is not required |
| SMCJ5.0CA-M3 | Same bidirectional function and AEC-Q101 rating, but in larger DO-214AB (SMC) package with higher RθJA (50 °C/W) | Needs more PCB area and delivers lower power density; better suited for higher average power dissipation | Choose when thermal margin exceeds requirements of DO-215AB or legacy board space allows SMC footprint |
Compared with SMAJ5.0A-M3/57T and SMCJ5.0CA-M3, the SMCG5.0CA-M3/57T uniquely combines bidirectional operation, AEC-Q101 qualification, and compact DO-215AB packaging - making it optimal for space-constrained automotive and industrial signal-line protection where polarity-agnostic clamping is essential.

FAQ
What does the "CA" suffix indicate in SMCG5.0CA-M3/57T?
The "CA" suffix denotes a bidirectional configuration - meaning the SMCG5.0CA-M3/57T provides symmetrical transient suppression in both polarities, with identical breakdown and clamping characteristics regardless of voltage polarity across its terminals. This eliminates orientation constraints during PCB placement and supports AC-coupled or floating signal lines.
Is SMCG5.0CA-M3/57T qualified for automotive use?
Yes, SMCG5.0CA-M3/57T is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. The M3 suffix further certifies halogen-free construction and JESD201 Class 2 whisker resistance - critical for under-hood reliability.
How does the SMCG5.0CA-M3/57T compare to unidirectional TVS diodes like SMAJ5.0A-M3/57T?
Unlike unidirectional types such as SMAJ5.0A-M3/57T, the SMCG5.0CA-M3/57T offers identical electrical performance in both directions - no cathode/anode distinction, no polarity-dependent clamping behavior. This makes it inherently safer for differential signaling, transformer-coupled lines, or any application where voltage reversal is possible.
What is the thermal performance of SMCG5.0CA-M3/57T on standard PCB pads?
When mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, SMCG5.0CA-M3/57T achieves RθJA = 75 °C/W. This allows safe dissipation of its 6.5 W rated power at TA = 50 °C and supports operation up to TJ = 150 °C without forced cooling - verified per JEDEC JESD51-7 test conditions.
Does SMCG5.0CA-M3/57T meet industry standards for flammability and environmental compliance?
Yes, SMCG5.0CA-M3/57T uses a molding compound rated UL 94 V-0 for flammability and carries the M3 suffix indicating halogen-free, RoHS-compliant construction. It also meets JESD201 Class 2 whisker resistance and is recognized under UL 497B (QVGQ2) for surge protection applications.
