Product details
Overview
SMCG6.5CA-M3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (PPPM), 133.9 A peak pulse current (IPPM), and clamps to ≤11.2 V at rated surge. It is AEC-Q101 qualified and halogen-free, targeting automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the SMCG6.5CA-M3/57T datasheet, SMCG6.5CA-M3/57T pinout, SMCG6.5CA-M3/57T application, or SMCG6.5CA-M3/57T equivalent, this page delivers verified electrical parameters, mechanical package details, real-world use cases, and validated alternative parts - all aligned with Vishay's 88457 specification revision (09-Jan-2024).
Technical Context
The SMCG6.5CA-M3/57T operates as a bidirectional avalanche diode, symmetrically clamping voltage transients in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and fast response (<1 ns), while low incremental surge resistance enables effective energy diversion during 10/1000 µs surges.
Thermally, it exhibits RθJA = 75 °C/W and RθJL = 15 °C/W, supporting 6.5 W power dissipation at TA = 50 °C on infinite heatsink. With TJ max = 150 °C and TSTG = –55 to +150 °C, it sustains operation in harsh automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal line operating margin. |
| VBR (min/max) | 7.22 V / 7.98 V at IT = 10 mA - Confirmed breakdown range ensures reliable turn-on across process variation and temperature. |
| VC @ IPPM | ≤11.2 V at 133.9 A - Clamping voltage under full 1500 W surge; determines maximum stress imposed on protected IC. |
| PPPM | 1500 W - Peak pulse power handling per 10/1000 µs waveform; defines transient energy absorption capability. |
| ID @ VWM | 500 µA - Reverse leakage at stand-off voltage; low value minimizes quiescent power loss and signal distortion. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive and high-ambient industrial locations. |
| Package | SMCG (DO-215AB) - Surface-mount gull-wing package with 8.0 mm × 8.0 mm copper pad layout; optimized for automated placement and thermal reliability. |
Pinout & Package
SMCG6.5CA-M3/57T uses the SMCG (DO-215AB) surface-mount package: gull-wing leads, matte tin-plated terminals, no polarity marking (bidirectional), and UL 94 V-0 molding compound. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal per Vishay spec.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional conduction path | No functional distinction between terminals; either lead connects to protected line or ground - identical clamping behavior in both directions. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, ADAS, and body electronics. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets JESD201 Class 2 whisker resistance and environmental compliance requirements for industrial and automotive supply chains. |
| Low incremental surge resistance | Enables tighter clamping (VC = 11.2 V) at high IPPM (133.9 A), reducing voltage overshoot on protected MOSFET gates or MCU I/O pins. |
| MSL Level 1 (J-STD-020) | Unlimited floor life at ≤30 °C/60% RH; supports standard SMT reflow without baking - reduces manufacturing overhead. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|

IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC input channels, mounted directly at connector entry point. Use Value: Maintains system uptime by absorbing 1500 W transients without degradation - validated per IEC 61000-4-5 (10/1000 µs). |
| Consumer Power Adapter Interface | Telecom Line Card Surge Protection |
Use Scenario: Safeguarding USB-C PD controller and level-shifter circuits against ESD and AC-line coupled surges in wall adapters. IC Role / Device Role / Timing Role: Secondary-stage TVS after common-mode choke, suppressing differential-mode transients on VBUS and CC lines. Use Value: Achieves >30 kV contact ESD immunity (IEC 61000-4-2) due to sub-1 ns response and low clamping voltage. | Use Scenario: Protecting Ethernet PHY and PoE interface ICs on telecom line cards from lightning-induced longitudinal surges. IC Role / Device Role / Timing Role: Bidirectional clamp on differential pairs (e.g., TX+/TX−), referenced to isolated ground plane. Use Value: Enables compliance with GR-1089-CORE (lightning surge) by clamping 10/1000 µs surges to <12 V while sustaining 1500 W peak power. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.5CA-E3/57T | Same VWM (6.5 V) and PPPM (1500 W), but SMA (DO-214AC) package - larger footprint (4.5 mm × 3.9 mm vs. SMCG's 7.87 mm × 3.8 mm), higher RθJA (90 °C/W). | Limited to non-AEC-Q101 applications; lower thermal performance restricts use in high-ambient automotive modules. | Select when board space allows larger package and AEC-Q101 is not required. |
| SMCJ6.5CA-M3 | Same VWM and bidirectional function, but SMC (DO-214AB) package - 7.11 mm × 6.22 mm, RθJA = 15 °C/W, higher IPPM (143 A), same VC (11.2 V). | Higher thermal mass supports longer surge durations; not qualified to AEC-Q101 (only industrial grade). | Prefer for industrial power supplies needing extended surge endurance where automotive qualification is unnecessary. |
Compared with SMAJ6.5CA-E3/57T and SMCJ6.5CA-M3, the SMCG6.5CA-M3/57T uniquely combines AEC-Q101 qualification, halogen-free construction, and compact DO-215AB packaging - making it optimal for space-constrained, high-reliability automotive signal protection where thermal and regulatory constraints are critical.

FAQ
What is the clamping voltage of SMCG6.5CA-M3/57T at its rated peak pulse current?
The SMCG6.5CA-M3/57T has a maximum clamping voltage (VC) of 11.2 V when subjected to its rated peak pulse current (IPPM) of 133.9 A under the standard 10/1000 µs waveform. This value is measured per Vishay Document Number 88457 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCG6.5CA-M3/57T maintains this clamping performance across its operational temperature range.
Is SMCG6.5CA-M3/57T suitable for automotive applications?
Yes, SMCG6.5CA-M3/57T is AEC-Q101 qualified per Vishay's documentation (Rev. 09-Jan-2024, Doc. 88457), confirming its suitability for automotive applications including engine control units, ADAS sensors, and body electronics. Its halogen-free M3 suffix, MSL Level 1 rating, and guaranteed operation from –55 °C to +150 °C make SMCG6.5CA-M3/57T appropriate for under-hood and cabin-mounted systems.
What does the "CA" suffix indicate in SMCG6.5CA-M3/57T?
The "CA" suffix in SMCG6.5CA-M3/57T denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions, with identical breakdown and clamping characteristics in either direction. Unlike unidirectional variants (e.g., SMCG6.5A), SMCG6.5CA-M3/57T has no cathode band marking and is used where polarity-independent protection is required.
How does the SMCG (DO-215AB) package of SMCG6.5CA-M3/57T compare thermally to SMA or SMC packages?
The SMCG (DO-215AB) package of SMCG6.5CA-M3/57T offers RθJA = 75 °C/W and RθJL = 15 °C/W, striking a balance between compact size (7.87 mm × 3.8 mm) and thermal performance. It outperforms SMA (RθJA ≈ 90 °C/W) in thermal resistance while occupying less PCB area than SMC (DO-214AB). This makes SMCG6.5CA-M3/57T especially effective in dense automotive layouts where both space and thermal management are constrained.
What is the maximum reverse leakage current for SMCG6.5CA-M3/57T at its stand-off voltage?
The maximum reverse leakage current (ID) for SMCG6.5CA-M3/57T is 500 µA at its stand-off voltage (VWM) of 6.5 V and TA = 25 °C, as specified in Vishay's SMCG5.0A–SMCG188CA datasheet (Doc. 88457). This low leakage ensures minimal impact on signal integrity and power budget in always-on sensor or communication interfaces where SMCG6.5CA-M3/57T is deployed.
