Product details
Overview
SMCG150A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) in the SMCG (DO-215AB) package, featuring a 150 V standoff voltage (VWM), 167–185 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamping voltage of 243 V at 6.2 A IPPM. It protects MOSFETs and ICs in automotive power circuits against inductive switching transients.
For engineers reviewing the SMCG150A-M3/57T datasheet, SMCG150A-M3/57T pinout, SMCG150A-M3/57T application, or SMCG150A-M3/57T equivalent, key selection criteria include clamping performance under 10/1000 µs surge, AEC-Q101 qualification for automotive use, halogen-free RoHS compliance (M3 suffix), and thermal resistance (RθJA = 75 °C/W) on standard 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, designed to shunt transient energy above its breakdown threshold while maintaining low leakage (<1.0 µA at VWM) and fast response time. Its glass-passivated junction ensures stable avalanche characteristics and long-term reliability under repetitive surge stress.
The SMCG150A-M3/57T uses a DO-215AB outline with gull-wing leads, rated for TJ = –55 °C to +150 °C operation and qualified to AEC-Q101. It delivers 243 V clamping at 6.2 A peak pulse current (IPPM) under 10/1000 µs waveform, with incremental surge resistance optimized for minimal voltage overshoot during ESD and load-dump events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 150 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| VBR min/max | 167 V / 185 V at 1.0 mA IT - Confirmed avalanche onset range; ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 243 V at 6.2 A - Clamped voltage during 10/1000 µs surge; directly limits stress on downstream MOSFET gate or IC input. |
| PPPM | 1500 W - Peak pulse power handling per 10/1000 µs waveform; supports high-energy transients in 12 V automotive systems. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on 8.0 mm × 8.0 mm copper pads; enables thermal design margin for sustained surge duty. |
| IFSM | 200 A - Non-repetitive forward surge rating (8.3 ms half-sine); validates robustness against battery reverse-connection or jump-start faults. |
| Leakage ID | ≤1.0 µA at VWM - Low reverse leakage preserves signal integrity and minimizes standby power loss in always-on modules. |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount gull-wing leaded case with matte tin-plated terminals, UL 94 V-0 molding compound, and M3 suffix indicating halogen-free, RoHS-compliant, industrial-grade construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry (unidirectional) | Connected to system ground or low-side return path; forms clamping loop with cathode during transient events. |
| Cathode | Reverse-biased terminal (marked with band) | Connected to protected line (e.g., 12 V rail); conducts avalanche current when line voltage exceeds VBR. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ150A-E3/57T | Same VWM (150 V) and PPPM (1500 W), but SMA (DO-214AC) package; RθJA = 85 °C/W; no AEC-Q101 qualification. | Not suitable for automotive underhood use; limited thermal performance on small PCB pads. | Select when cost-sensitive industrial designs require legacy footprint compatibility and AEC-Q101 is not mandated. |
| SMCJ150A-M3 | Same electrical specs and AEC-Q101 qualification, but SMC (DO-214AB) package; larger footprint (7.11 mm × 6.22 mm vs. SMCG's 7.11 mm × 5.59 mm) and higher RθJA (80 °C/W). | Requires PCB layout revision; less space-efficient in dense automotive ECUs. | Choose only if existing SMC footprint is locked and thermal margin allows higher RθJA. |
Compared with SMAJ150A-E3/57T and SMCJ150A-M3, the SMCG150A-M3/57T offers superior thermal performance (75 °C/W), smaller DO-215AB footprint, and verified AEC-Q101 compliance-making it the optimal choice for space-constrained, thermally demanding automotive power protection.

FAQ
What is the clamping voltage of the SMCG150A-M3/57T under standard 10/1000 µs surge conditions?
The SMCG150A-M3/57T has a maximum clamping voltage (VC) of 243 V at 6.2 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per JEDEC test conditions on minimum recommended pad layout and defines the upper voltage limit imposed on protected circuitry during transient events. The SMCG150A-M3/57T maintains this clamping performance across its full operating temperature range.
Is the SMCG150A-M3/57T qualified for automotive applications?
Yes, the SMCG150A-M3/57T is AEC-Q101 qualified, having passed all required stress tests including high-temperature operating life, temperature cycling, and surge robustness. Its M3 suffix confirms halogen-free, RoHS-compliant construction, and the device is explicitly listed in Vishay's AEC-Q101 qualified product matrix. The SMCG150A-M3/57T is approved for use in engine control units, body control modules, and other automotive underhood applications.
What does the "M3" suffix mean in SMCG150A-M3/57T?
The "M3" suffix in SMCG150A-M3/57T indicates halogen-free, RoHS-compliant, industrial-grade construction per Vishay's ordering nomenclature. It specifies matte tin-plated leads, compliance with JESD 201 Class 2 whisker resistance, and adherence to material categorization standards defined in Vishay document 99912. The SMCG150A-M3/57T meets UL 94 V-0 flammability rating and is rated for MSL Level 1 handling at 260 °C peak reflow temperature.
How does the SMCG150A-M3/57T differ from the SMCG150AHE3/57T variant?
The SMCG150A-M3/57T and SMCG150AHE3/57T share identical electrical specifications and DO-215AB packaging, but differ in qualification and material content: the HE3 suffix denotes AEC-Q101 qualification plus RoHS compliance, while M3 adds halogen-free composition. The SMCG150A-M3/57T is both AEC-Q101 qualified and halogen-free, making it suitable for automotive applications with strict environmental requirements, whereas HE3 is AEC-Q101 qualified but not necessarily halogen-free.
What is the thermal resistance of the SMCG150A-M3/57T, and how is it measured?
The SMCG150A-M3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W, measured on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal per JEDEC standards. This value assumes standard FR-4 PCB construction and natural convection cooling. The SMCG150A-M3/57T's low RθJA enables effective heat dissipation during repetitive surge events, supporting reliable operation in thermally constrained automotive modules.
