Product details
Overview
SMCG60A-M3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMCG (DO-215AB) package, with a standoff voltage of 60 V, breakdown voltage range of 66.7–73.7 V at 1 mA, peak pulse power rating of 1500 W (10/1000 µs), clamping voltage of 96 V at 15.5 A, and AEC-Q101 qualification for automotive-grade reliability. It protects MOSFETs and signal lines in automotive powertrain control modules.
For engineers reviewing the SMCG60A-M3/9AT datasheet, SMCG60A-M3/9AT pinout, SMCG60A-M3/9AT application, or SMCG60A-M3/9AT equivalent, key selection criteria include unidirectional polarity, 60 V VWM, 1500 W PPPM, DO-215AB thermal performance (RθJA = 75 °C/W), and halogen-free RoHS compliance per M3 suffix.
Technical Context
This TVS diode operates as a clamping-type overvoltage protector using an avalanche junction. Its glass-passivated chip enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing ESD and load-dump transients in 12 V automotive systems.
The device is rated for TJ = –55 to +150 °C, supports 200 A IFSM (8.3 ms half-sine), and meets J-STD-020 MSL Level 1 with 260 °C reflow peak. Its bidirectional counterpart would use "CA" suffix; SMCG60A-M3/9AT is strictly unidirectional, with cathode marked by band.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines system-level DC rail compatibility. |
| VBR min/max | 66.7 V / 73.7 V at 1 mA - Ensures consistent avalanche initiation across production lots under standardized test conditions. |
| VC @ IPPM | 96 V at 15.5 A - Clamping voltage during 10/1000 µs surge; determines maximum stress imposed on protected downstream ICs. |
| PPPM | 1500 W - Peak transient energy handling capacity; validates suitability for ISO 7637-2 Pulse 5a (load dump) suppression. |
| Package | SMCG (DO-215AB) - Low-profile SMD outline with 7.11 mm × 6.22 mm footprint and 1.47 mm height; optimized for automated placement and thermal pad coupling. |
| Qualification | AEC-Q101 qualified - Confirmed reliability for automotive underhood applications including temperature cycling, humidity, and mechanical shock. |
| RoHS Status | Halogen-free, RoHS compliant (M3 suffix) - Meets automotive material compliance requirements and JESD201 Class 2 whisker resistance. |
Pinout & Package
Package: SMCG (DO-215AB), surface-mount gull-wing leaded case with cathode band marking. Dimensions: 0.280" × 0.245" × 0.058" (7.11 mm × 6.22 mm × 1.47 mm). Mounting requires 8.0 mm × 8.0 mm copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias | Connected to ground or low-side reference in unidirectional clamp configuration; must be routed with low-inductance path. |
| Cathode (banded end) | Current exit point in forward bias; high-impedance node in reverse standby | Connected to protected line (e.g., 12 V supply rail); band orientation ensures correct PCB placement and polarity verification. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile DO-215AB package | Enables high-density layout in space-constrained engine control units without compromising thermal pad area. |
| Glass-passivated junction | Ensures stable breakdown characteristics over lifetime and immunity to moisture-induced parameter drift. |
| 1500 W peak pulse power | Supports single-event suppression of automotive load-dump transients up to 40 V above nominal 12 V rail. |
| AEC-Q101 qualification | Validates robustness for under-hood deployment including 1000-cycle temperature cycling (–40 °C to +125 °C). |
| Halogen-free M3 construction | Meets automotive OEM material declarations (e.g., GMW3172, Ford WSS-M99P9999-A1) and eliminates corrosive halogen emissions during reflow. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A-E3/57T | Same VWM (60 V) and PPPM (1500 W), but SMA (DO-214AC) package; RθJA = 85 °C/W vs. 75 °C/W for SMCG. | Less effective thermal dissipation in high-ambient environments; not AEC-Q101 qualified. | Select when cost sensitivity outweighs automotive qualification or thermal margin requirements. |
| SMCJ60A-M3 | Same VWM and AEC-Q101 qualification, but SMC (DO-214AB) package; higher RθJA (90 °C/W) and larger footprint (7.11 mm × 6.22 mm × 2.62 mm). | Lower power density and reduced board space efficiency; same clamping performance but slower thermal recovery. | Choose only if legacy SMC footprint compatibility is mandatory and height constraints allow 2.62 mm profile. |
Compared with SMAJ60A-E3/57T and SMCJ60A-M3, SMCG60A-M3/9AT delivers superior thermal performance (75 °C/W), smallest height (1.47 mm), and verified AEC-Q101 compliance-making it optimal for next-generation compact automotive ECUs where thermal headroom and qualification rigor are non-negotiable.

FAQ
What is the clamping voltage of SMCG60A-M3/9AT at its rated peak pulse current?
The SMCG60A-M3/9AT has a maximum clamping voltage (VC) of 96 V at 15.5 A peak pulse current (IPPM), measured under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is confirmed in Vishay's datasheet revision 09-Jan-2024, page 2. The SMCG60A-M3/9AT maintains this clamping performance across its full operating temperature range.
Is SMCG60A-M3/9AT suitable for automotive under-hood applications?
Yes, SMCG60A-M3/9AT is AEC-Q101 qualified and rated for TJ = –55 °C to +150 °C, making it suitable for under-hood automotive applications including engine control units and transmission control modules. Its halogen-free M3 construction and J-STD-020 MSL Level 1 rating further support reflow compatibility and long-term reliability in high-temperature, high-vibration environments. The SMCG60A-M3/9AT meets these requirements without derating.
What does the "M3" suffix indicate in SMCG60A-M3/9AT?
The "M3" suffix in SMCG60A-M3/9AT denotes halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance requirements, and industrial-grade qualification. It distinguishes the part from "E3" (standard RoHS) and "HM3" (AEC-Q101 + halogen-free) variants. All M3-suffix devices, including SMCG60A-M3/9AT, are approved for automotive and industrial use with verified material compliance.
How does the SMCG (DO-215AB) package compare thermally to SMA (DO-214AC)?
The SMCG (DO-215AB) package used by SMCG60A-M3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W, versus ~85 °C/W for SMA (DO-214AC) packages like SMAJ60A. This 10 °C/W improvement enables higher sustained power handling on identical PCB layouts and supports more aggressive derating in high-ambient environments. The SMCG60A-M3/9AT leverages this advantage for automotive thermal margins.
Can SMCG60A-M3/9AT be used in bidirectional protection circuits?
No, SMCG60A-M3/9AT is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix and cathode band marking. Bidirectional operation requires the "CA" variant (e.g., SMCG60CA), which has symmetrical breakdown in both directions. Using SMCG60A-M3/9AT in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. Always verify polarity designation before layout.
