Product details
Overview
SMCG60CA-M3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for high-energy surge protection with 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM). It clamps transients to ≤96 V at 15.5 A (10/1000 µs waveform) and is AEC-Q101 qualified for automotive electronics.
For engineers reviewing the SMCG60CA-M3/57T datasheet, SMCG60CA-M3/57T pinout, SMCG60CA-M3/57T application, or SMCG60CA-M3/57T equivalent, key selection criteria include bidirectional clamping capability, halogen-free RoHS compliance (M3 suffix), 150 °C max junction temperature, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a voltage-clamping protector using an avalanche breakdown mechanism, with symmetrical bidirectional conduction enabling suppression of both positive and negative transients without polarity sensitivity. Its low incremental surge resistance and fast response time ensure effective protection against ESD, lightning-induced surges, and inductive switching spikes.
The SMCG60CA-M3/57T is thermally rated for 6.5 W power dissipation at TA = 50 °C, with RθJA = 75 °C/W and RθJL = 15 °C/W, and meets J-STD-020 MSL Level 1 (260 °C peak reflow). It exhibits ≤1.0 µA reverse leakage at VWM and is validated for automotive-grade reliability per AEC-Q101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 66.7 V / 73.7 V - Breakdown occurs within this range at 1 mA test current, ensuring predictable turn-on |
| VC @ IPPM | ≤96 V - Clamped voltage at 15.5 A peak pulse current (10/1000 µs), defining worst-case protected line voltage |
| PPPM | 1500 W - Peak surge energy handling capacity under standardized transient waveform |
| ID @ VWM | ≤1.0 µA - Low leakage preserves signal integrity and minimizes standby power loss |
| TJ max | +150 °C - Enables operation in under-hood automotive environments and industrial enclosures |
| Package | SMCG (DO-215AB) - Surface-mount, low-profile, gull-wing leaded package optimized for automated assembly |
Pinout & Package
SMCG60CA-M3/57T uses the SMCG (DO-215AB) package: a surface-mount, gull-wing leaded case with no polarity marking (bidirectional configuration). Leads are matte tin plated, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative half-cycle) | Conducts during negative voltage excursions; symmetric with cathode for bidirectional operation |
| Cathode | Transient current entry (positive half-cycle) | Conducts during positive voltage excursions; functionally identical to anode in CA devices |
Key Features

|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| Halogen-free & RoHS compliant (M3) | Meets environmental compliance requirements for industrial and automotive supply chains without compromising thermal robustness |
| MSL Level 1 rating | Enables single-pass reflow at 260 °C peak without moisture-related damage or popcorn effect |
| Glass passivated junction | Ensures stable electrical characteristics and long-term reliability under thermal cycling and humidity stress |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a/5a) |

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-E3/52T | Unidirectional; same VWM/VBR/PPPM but lacks bidirectional symmetry and AEC-Q101 qualification | Requires polarity-aware PCB layout; not approved for automotive use | Select only if unidirectional protection suffices and automotive qualification is unnecessary |
| SMCJ60CA | Same bidirectional functionality and VWM/VBR specs, but uses legacy M3/57T-compatible packaging without halogen-free assurance | May not meet latest environmental compliance mandates for Tier 1 automotive suppliers | Prefer SMCG60CA-M3/57T when halogen-free and full RoHS compliance are contractually required |
Compared with SMAJ60A-E3/52T and SMCJ60CA, the SMCG60CA-M3/57T uniquely combines bidirectional clamping, AEC-Q101 qualification, and halogen-free construction in the DO-215AB footprint-enabling drop-in compliance in next-gen automotive and industrial designs without layout or qualification rework.

FAQ
What is the clamping voltage of SMCG60CA-M3/57T at its rated peak pulse current?
The SMCG60CA-M3/57T 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 circuits during surge events and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2. The SMCG60CA-M3/57T maintains this clamping performance across its full operating temperature range.
Is SMCG60CA-M3/57T suitable for automotive applications?
Yes, SMCG60CA-M3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its construction features glass passivation, MSL Level 1 reflow compatibility, and operation up to +150 °C junction temperature-meeting critical automotive reliability requirements. The SMCG60CA-M3/57T is listed in Vishay's AEC-Q101 qualified product documentation.
What does the "M3" suffix indicate in SMCG60CA-M3/57T?
The "M3" suffix in SMCG60CA-M3/57T denotes halogen-free, RoHS-compliant construction with industrial-grade reliability. It distinguishes the part from "E3" (RoHS-compliant but not halogen-free) and "HM3" (halogen-free + AEC-Q101 qualified). All variants share identical electrical specs, but SMCG60CA-M3/57T satisfies strict environmental mandates for modern automotive and industrial supply chains.
How does SMCG60CA-M3/57T differ from unidirectional TVS diodes like SMCG60A-M3/57T?
SMCG60CA-M3/57T is bidirectional, meaning it clamps transients of either polarity symmetrically, with no cathode marking and identical VBR/VWM in both directions. In contrast, SMCG60A-M3/57T is unidirectional, requires correct polarity orientation, and includes a cathode band. The "CA" suffix explicitly identifies bidirectional functionality-critical for AC-coupled or polarity-agnostic protection schemes where SMCG60CA-M3/57T eliminates layout constraints.
What PCB pad layout is recommended for optimal thermal and surge performance of SMCG60CA-M3/57T?
Vishay specifies a minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad area per terminal for SMCG60CA-M3/57T to achieve rated PPPM and thermal performance. This layout ensures adequate heat spreading and current handling during 10/1000 µs surges. Deviating from this pad size reduces peak power derating and may elevate junction temperature beyond the 150 °C limit. The SMCG60CA-M3/57T datasheet (page 4) provides exact dimensional drawings and thermal derating curves.
