Product details
Overview
SMCG5.0A-M3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 5.0 V stand-off voltage (VWM), 6.40–7.07 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (PPPM), 163 A peak pulse current (IPPM), and clamps transients to ≤9.20 V at rated surge. It is widely deployed in automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the SMCG5.0A-M3/9AT datasheet, SMCG5.0A-M3/9AT pinout, SMCG5.0A-M3/9AT application, or SMCG5.0A-M3/9AT equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, halogen-free RoHS compliance, thermal resistance (RθJA = 75 °C/W), and real-world protection use cases - all critical for ESD/surge hardening in high-reliability embedded systems.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, optimized for fast response to transient events (10/1000 µs waveform). Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, while the DO-215AB package supports automated SMT placement and meets UL 94 V-0 flammability rating.
Rated for -55 °C to +150 °C junction temperature, it delivers 6.5 W steady-state power dissipation at TA = 50 °C and exhibits 1000 µA maximum reverse leakage at VWM. It is qualified to AEC-Q101 for automotive applications and complies with JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal line bias margin. |
| VBR (min/max) | 6.40 V / 7.07 V at IT = 10 mA - Tight breakdown window ensures predictable turn-on across production lots. |
| VC @ IPPM | ≤9.20 V at 163 A - Clamping voltage under full 1500 W surge; determines protected IC's voltage stress ceiling. |
| PPPM | 1500 W - Peak transient energy handling capability per 10/1000 µs waveform; enables protection against ISO 7637-2 Pulse 1/2/5a. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard 8.0 mm × 8.0 mm copper pads; guides PCB thermal layout. |
| Leakage ID | ≤1000 µA at VWM - Low standby current preserves signal integrity and battery life in always-on circuits. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |

| Consumer Power Adapter Interface | Telecom Line Card Surge Protection |
Use Scenario: Shielding USB-C PD port power path and CC line from hot-plug transients and external ESD in wall adapters and docking stations. IC Role / Device Role / Timing Role: Unidirectional TVS on VBUS and CC lines, leveraging low capacitance and fast response to preserve high-speed signaling integrity. Use Value: Clamps 8 kV contact ESD (IEC 61000-4-2) within nanoseconds while adding <0.5 pF parasitic capacitance to signal paths. |
Use Scenario: Providing primary-level surge immunity on Ethernet PHY or xDSL line driver outputs in telecom access equipment exposed to lightning-induced surges. IC Role / Device Role / Timing Role: First-stage protector on differential pair outputs, coordinated with secondary GDT or polymer PTC for multi-stage protection. Use Value: Handles 10/1000 µs surges up to 163 A while maintaining tight VBR tolerance (±5 %), enabling precise coordination with downstream protectors. |
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 | Same VWM (5.0 V) and PPPM (400 W), but lower surge rating (40 A IPPM); SMA (DO-214AC) package, higher RθJA (110 °C/W). | Limited to lower-energy transients (e.g., IEC 61000-4-5 Level 2); unsuitable for automotive load dump. | Select SMAJ5.0A only for cost-sensitive consumer applications where 1500 W surge immunity is not required. |
| SMCJ5.0A | Same VWM (5.0 V) and DO-214AB package, but higher PPPM (1500 W) and IPPM (174 A); not AEC-Q101 qualified; M3 suffix available. | Matches surge capability but lacks automotive qualification; requires separate reliability validation for automotive use. | Choose SMCJ5.0A when AEC-Q101 is not mandated and legacy DO-214AB footprint compatibility is prioritized. |
Compared with SMAJ5.0A and SMCJ5.0A, SMCG5.0A-M3/9AT uniquely combines AEC-Q101 qualification, halogen-free construction, and DO-215AB's optimized thermal performance (RθJA = 75 °C/W) - making it the preferred choice for next-generation automotive and industrial designs demanding certified reliability and thermal headroom.

FAQ
What is the clamping voltage of SMCG5.0A-M3/9AT at its rated peak pulse current?
The SMCG5.0A-M3/9AT has a maximum clamping voltage (VC) of 9.20 V when subjected to its rated peak pulse current (IPPM) of 163 A under the standard 10/1000 µs waveform. This value is measured at the device terminals with the recommended 8.0 mm × 8.0 mm copper pad layout and defines the upper voltage limit imposed on protected circuitry during surge events.
Is SMCG5.0A-M3/9AT suitable for automotive applications?
Yes, SMCG5.0A-M3/9AT is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, ADAS sensors, and body electronics. Its qualification covers temperature cycling, high-temperature reverse bias (HTRB), and ESD testing per AEC standards, and its 1500 W surge rating supports ISO 7637-2 Pulse 5a load-dump protection requirements.
What does the "M3" suffix indicate in SMCG5.0A-M3/9AT?
The "M3" suffix in SMCG5.0A-M3/9AT denotes halogen-free, RoHS-compliant construction meeting Vishay's industrial-grade material specifications. It confirms compliance with JEDEC JESD201 Class 2 whisker resistance and UL 94 V-0 flammability rating - critical for environmentally regulated and high-reliability manufacturing environments.
How does the SMCG (DO-215AB) package compare thermally to SMA (DO-214AC) or SMC (DO-214AB)?
The SMCG (DO-215AB) package used by SMCG5.0A-M3/9AT offers a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W on standard 8.0 mm × 8.0 mm pads - significantly lower than SMA (110 °C/W) and competitive with SMC (65–70 °C/W). This improves power derating capability and enables sustained operation under repeated surge conditions.
Can SMCG5.0A-M3/9AT be used in bidirectional configurations?
No, SMCG5.0A-M3/9AT is a unidirectional TVS diode, identified by its cathode band marking. Bidirectional variants in the same family carry the "CA" suffix (e.g., SMCG5.0CA). Using SMCG5.0A-M3/9AT in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit.
