Product details
Overview
SMCG6.0CA-M3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) in the SMCG (DO-215AB) surface-mount package, designed for clamping voltage transients on signal and power lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (10/1000 µs), <10.3 V clamping voltage at 145.6 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG6.0CA-M3/57T datasheet, SMCG6.0CA-M3/57T pinout, SMCG6.0CA-M3/57T application, or SMCG6.0CA-M3/57T equivalent, this device is selected for robust ESD and surge protection in automotive sensor interfaces, industrial I/O lines, and bidirectional communication buses where low clamping voltage and halogen-free compliance are critical.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions - confirmed by VBR min/max and VC values applying "in both directions" per Vishay documentation. Its glass-passivated junction ensures stable breakdown behavior under repetitive surge stress, and MSL Level 1 rating supports lead-free reflow without popcorn cracking.
The device uses a low-inductance DO-215AB package optimized for high-speed transient response (<1 ns typical), and its thermal resistance (RθJA = 75 °C/W) is specified with 8.0 mm × 8.0 mm copper pads - a layout-dependent value critical for sustained power dissipation in automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse stand-off voltage before significant leakage; defines safe operating margin below breakdown in bidirectional signal lines. |
| VBR @ IT = 10 mA | 6.67–7.37 V - guaranteed breakdown range; ensures predictable clamping onset across production lot and temperature. |
| VC @ IPPM | 10.3 V at 145.6 A - clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected downstream ICs. |
| PPPM | 1500 W - peak pulse power handling capability; enables protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) when properly laid out. |
| ID @ VWM | 1000 µA max - reverse leakage at rated stand-off; low enough to avoid loading sensitive analog or high-impedance sensor inputs. |
| TJ max | +150 °C - maximum junction temperature; supports operation in under-hood automotive environments and industrial enclosures. |
| Package | SMCG (DO-215AB) - surface-mount gull-wing package with matte tin leads; compatible with automated placement and J-STD-002 soldering. |
Pinout & Package
SMCG6.0CA-M3/57T is housed in the SMCG (DO-215AB) package - a dual-leaded, gull-wing surface-mount outline with no polarity marking for bidirectional variants. The case conforms to JEDEC DO-215AB mechanical dimensions (0.220–0.245" body length, 0.115–0.125" width, 0.095" height), UL 94 V-0 molding compound, and MSL Level 1 moisture sensitivity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode / Cathode (bidirectional) | Non-polarized terminal; functions as either anode or cathode depending on instantaneous voltage polarity - no band marking required. |
| Terminal 2 | Anode / Cathode (bidirectional) | Electrically symmetric counterpart to Terminal 1; completes bidirectional clamping path across protected line pair. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, ADAS sensors, and infotainment interfaces per stress test requirements. |
| Halogen-free & RoHS compliant (M3 suffix) | Meets EU Directive 2011/65/EU and IPC-1752A material declarations; eliminates brominated flame retardants without compromising UL 94 V-0 rating. |
| Low incremental surge resistance | Enables tighter clamping (VC − VBR ≈ 3.6 V) versus competing TVS diodes, reducing voltage overshoot on protected nodes. |
| Very fast response time | Sub-nanosecond turn-on ensures clamping activation before transient energy couples into sensitive circuitry - critical for CAN FD and LIN bus protection. |
| Glass passivated chip junction | Improves long-term stability of VBR and leakage under thermal cycling and humidity exposure, extending field life in harsh environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/57T | Unidirectional only; same VWM/VBR/VC specs but lacks symmetrical clamping; SMA package (DO-214AC) vs. SMCG (DO-215AB). | Requires polarity-aware layout; unsuitable for true bidirectional lines like CAN or RS-485 without external biasing. | Select only if unidirectional protection suffices and board space allows larger SMA footprint. |
| TPSMF6.0A | Same bidirectional function and 6.0 V VWM, but lower PPPM (1000 W); SOD-123FL package with higher RθJA (120 °C/W). | Limited to lower-energy transients; not AEC-Q101 qualified; insufficient for automotive load-dump scenarios. | Consider for cost-sensitive consumer applications with moderate surge exposure and no automotive qualification requirement. |
Compared with SMAJ6.0A-E3/57T and TPSMF6.0A, SMCG6.0CA-M3/57T uniquely combines bidirectional symmetry, 1500 W surge capacity, AEC-Q101 qualification, and halogen-free construction - making it the only option among the three validated for automotive-grade CAN bus and sensor interface protection without design compromise.

FAQ
What does the "CA" suffix indicate in SMCG6.0CA-M3/57T?
The "CA" suffix denotes a bidirectional configuration - meaning SMCG6.0CA-M3/57T provides symmetrical transient suppression in both polarities, with identical VBR, VC, and IPPM characteristics regardless of voltage polarity. This distinguishes it from unidirectional variants (e.g., SMCG6.0A) that require correct cathode orientation and cannot clamp negative-going transients without external circuitry. SMCG6.0CA-M3/57T has no polarity marking.
Is SMCG6.0CA-M3/57T suitable for protecting CAN FD bus lines?
Yes - SMCG6.0CA-M3/57T is widely deployed for CAN FD protection due to its 10.3 V clamping voltage at 145.6 A, sub-nanosecond response, and low junction capacitance (~15 pF at 0 V). Its bidirectional nature matches the differential signaling of CAN_H/CAN_L, and AEC-Q101 qualification confirms suitability for automotive networks. Layout must follow controlled-impedance routing and minimize trace inductance to preserve clamping effectiveness for 5 Mbps operation.
How does the "M3" suffix affect compliance and assembly of SMCG6.0CA-M3/57T?
The "M3" suffix indicates halogen-free, RoHS-compliant construction with matte tin-plated leads qualified to JESD 201 Class 2 whisker resistance. It meets IPC/JEDEC standards for lead-free reflow (peak 260 °C, MSL Level 1), and requires no special solder paste or profile adjustments beyond standard Pb-free processes. SMCG6.0CA-M3/57T is fully compatible with automated pick-and-place and reflow soldering in high-volume manufacturing.
What is the maximum allowable PCB pad size for optimal thermal performance of SMCG6.0CA-M3/57T?
Vishay specifies thermal resistance (RθJA = 75 °C/W) using 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal - the minimum recommended layout for rated power dissipation. Reducing pad area increases junction temperature and de-rates PPPM; increasing pad size or adding internal copper planes improves heat spreading but does not change the published RθJA value unless re-characterized. For automotive applications, maintain at least this pad size and ensure ≥2 oz copper weight.
Can SMCG6.0CA-M3/57T replace SMCG6.0A-M3/57T in an existing design?
No - SMCG6.0CA-M3/57T is bidirectional while SMCG6.0A-M3/57T is unidirectional; they are not functionally interchangeable without circuit review. Replacing SMCG6.0A-M3/57T (cathode-marked, polarity-sensitive) with SMCG6.0CA-M3/57T (no marking, symmetrical) may cause improper clamping on unidirectional rails or violate layout assumptions. Verify signal topology: use SMCG6.0CA-M3/57T only where true bidirectional protection is required, such as across differential pairs or AC-coupled lines.
