Product details
Overview
SMCG54A-M3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMCG (DO-215AB) package, featuring a 54 V standoff voltage (VWM), 60.0–66.3 V breakdown voltage (VBR), 1500 W peak pulse power (10/1000 µs), 17.2 A peak pulse current (IPPM), and 87.1 V clamping voltage (VC). It protects MOSFETs and ICs against inductive switching transients in automotive powertrain control modules.
For engineers reviewing the SMCG54A-M3/9AT datasheet, SMCG54A-M3/9AT pinout, SMCG54A-M3/9AT application, or SMCG54A-M3/9AT equivalent, this AEC-Q101 qualified, halogen-free, RoHS-compliant TVS offers validated surge robustness for 12 V/24 V automotive systems requiring IEC 61000-4-5 Level 3 immunity and stable clamping under repetitive 8.3 ms surge conditions.
Technical Context
This device operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast transient suppression (<1 ps response) and low incremental surge resistance. Its DO-215AB package enables automated placement and meets MSL level 1 (260 °C reflow peak).
Designed for primary-side overvoltage protection in DC-fed circuits, it conducts only during reverse overvoltage events - with cathode band marking - and sustains 200 A non-repetitive forward surge (8.3 ms half-sine). Thermal resistance is 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 54 V - Maximum continuous reverse operating voltage before clamping begins; sets system-level overvoltage trip threshold for 12 V/24 V automotive rails. |
| VBR @ IT = 1 mA | 60.0–66.3 V - Breakdown voltage range defining reliable avalanche initiation; ensures consistent turn-on across temperature and unit variation. |
| VC @ IPPM | 87.1 V - Clamping voltage at 17.2 A peak pulse; limits protected circuit stress to safe margin below IC absolute maximum ratings. |
| PPPM | 1500 W - Peak pulse power handling per 10/1000 µs waveform; supports IEC 61000-4-5 surge testing up to 1 kV/2 Ω coupling. |
| IFSM | 200 A - Non-repetitive forward surge rating (8.3 ms half-sine); withstands load-dump transients without degradation. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood environments with minimal derating. |
| Package | SMCG (DO-215AB) - Surface-mount gull-wing package with matte tin leads; compatible with J-STD-002 solderability and JESD22-B102 whisker testing. |
Pinout & Package
SMCG54A-M3/9AT uses the DO-215AB (SMCG) package: a 2-terminal surface-mount gull-wing outline with cathode band marking on the anode side of the body. Terminals are matte tin-plated, solderable per J-STD-002, and rated for JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to ground or low-side return path; carries full surge current during clamping events. |
| Cathode | Current exit terminal during reverse clamping | Connected to protected line (e.g., battery rail); defines polarity-sensitive placement - band denotes cathode end. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and transmission control modules per stress test requirements. |
| Halogen-free & RoHS compliant (M3 suffix) | Meets automotive environmental standards and enables use in green manufacturing processes without compromising surge performance. |
| Low incremental surge resistance | Minimizes VC overshoot during high-di/dt transients, improving protection margin for sensitive gate drivers and microcontrollers. |

Applications
| Automotive Load-Dump Protection | Industrial Motor Drive Gate Protection |
|---|---|

IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed at connector interface to shunt transients before signal conditioning stages. Use Value: 1.0 µA max leakage at 54 V ensures no impact on logic thresholds; 87.1 V clamping preserves MCU I/O integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ54A-E3/57T | Same VWM/VC, but SMA (DO-214AC) package; 1000 W PPPM; not AEC-Q101 qualified. | Limited to industrial/commercial use; lower surge rating reduces margin for automotive load-dump compliance. | Select when cost or legacy footprint compatibility outweighs AEC-Q101 and 1500 W requirement. |
| SMCJ54A-M3/9AT | Same SMCG package and AEC-Q101 rating, but 5.0 kW PPPM; higher VC (93.6 V); larger junction area. | Better suited for 48 V systems or where higher energy absorption is needed; clamping voltage exceeds SMCG54A-M3/9AT by 6.5 V. | Choose for enhanced surge margin in next-gen EV architectures where 54 V nominal rails require >1500 W headroom. |
Compared with SMAJ54A-E3/57T and SMCJ54A-M3/9AT, SMCG54A-M3/9AT delivers optimal balance of automotive qualification, 1500 W capability, and tight 87.1 V clamping - making it the preferred choice for space-constrained 12 V/24 V ECUs needing verified AEC-Q101 reliability without over-spec'ing surge capacity.

FAQ
What is the clamping voltage of SMCG54A-M3/9AT at its rated peak pulse current?
The SMCG54A-M3/9AT has a maximum clamping voltage (VC) of 87.1 V at its specified peak pulse current (IPPM) of 17.2 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's official datasheet revision 09-Jan-2024. The clamping performance ensures protected components remain within safe operating limits during standardized surge events. SMCG54A-M3/9AT maintains this specification across its full operating temperature range (-55 °C to +150 °C).
Is SMCG54A-M3/9AT suitable for automotive applications?
Yes, SMCG54A-M3/9AT is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, body electronics, and powertrain modules. Its halogen-free (M3) construction, MSL Level 1 rating, and validated performance under load-dump (ISO 7637-2 Pulse 5a) and ESD (IEC 61000-4-2) conditions confirm suitability. SMCG54A-M3/9AT meets all stress-test requirements defined in the AEC-Q101 standard, including temperature cycling, humidity bias, and high-temperature operating life.
What does the "M3" suffix indicate in SMCG54A-M3/9AT?
The "M3" suffix in SMCG54A-M3/9AT denotes halogen-free, RoHS-compliant construction with industrial-grade reliability and JESD201 Class 2 whisker resistance. It distinguishes the part from "E3" (RoHS-compliant but not halogen-free) and "HM3" (AEC-Q101 qualified + halogen-free). SMCG54A-M3/9AT carries both AEC-Q101 qualification and M3 environmental compliance, verified per Vishay document 88457. This dual certification supports stringent automotive and green manufacturing requirements.
How does SMCG54A-M3/9AT differ from SMCG54AHE3/9AT?
SMCG54A-M3/9AT and SMCG54AHE3/9AT share identical electrical specs and DO-215AB packaging, but differ in qualification: SMCG54AHE3/9AT is AEC-Q101 qualified *and* halogen-free (HE3 = Halogen-free + AEC-Q101), while SMCG54A-M3/9AT is halogen-free and RoHS-compliant but not AEC-Q101 qualified - however, per Vishay's official ordering table and datasheet footnote (1), SMCG54A-M3/9AT *is* AEC-Q101 qualified. Correction: both variants meet AEC-Q101; the distinction lies in internal process traceability - HE3 denotes enhanced process control for mission-critical applications. SMCG54A-M3/9AT remains fully qualified for standard automotive use.
What PCB pad layout is recommended for optimal thermal and surge performance of SMCG54A-M3/9AT?
Vishay specifies a minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad per terminal for SMCG54A-M3/9AT to achieve rated 1500 W pulse power and 75 °C/W thermal resistance. These pads must be connected to internal ground/power planes via multiple thermal vias. The layout directly impacts IPPM derating above 25 °C - per Figure 2 in datasheet 88457. SMCG54A-M3/9AT performance data (including VC and PPPM) is validated only on this pad configuration; smaller pads reduce surge capability and increase junction temperature.
