Product details
Overview
SMBG6.0CA-M3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection 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, 600 W peak pulse power (10/1000 µs), clamping voltage of 10.3 V at 58.3 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMBG6.0CA-M3/52 datasheet, SMBG6.0CA-M3/52 pinout, SMBG6.0CA-M3/52 application, or SMBG6.0CA-M3/52 equivalent, key selection criteria include bidirectional clamping behavior, low clamping ratio (VC/VBR ≈ 1.47), halogen-free RoHS compliance (M3 suffix), and suitability for I/O line protection in harsh ESD/lightning environments.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 6.0 V), then rapidly avalanches into low-impedance conduction when transient voltage exceeds VBR. Its bidirectional symmetry enables protection on AC-coupled or floating lines without polarity concerns.
It delivers 600 W peak pulse power per 10/1000 µs waveform with <1 ns response time, low incremental surge resistance (Rdyn ≈ 0.17 Ω derived from ΔVC/ΔIPPM), and thermal resistance RθJA = 100 °C/W on 5 mm × 5 mm copper pads - enabling reliable operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working margin below clamping threshold |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Ensures consistent avalanche initiation across production lot; tight 10.4% tolerance supports predictable protection window |
| VC @ IPPM | 10.3 V at 58.3 A - Clamping voltage during 600 W transient; limits downstream IC stress to safe levels per IEC 61000-4-5 Level 4 |
| IPPM | 58.3 A - Peak surge current supported with 10/1000 µs waveform; validates protection against induced lightning surges |
| PPPM | 600 W - Sustained transient energy handling capacity; enables single-device protection for CAN, LIN, USB, and sensor interfaces |
| TJ max | +150 °C - Junction temperature limit; supports under-hood automotive placement and industrial ambient conditions |
| Qualification | AEC-Q101 qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥ 8 kV) |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CA | Same VWM/VBR/VC, but lower PPPM = 600 W (same rating) and higher IPPM = 62.0 A; SMB (DO-214AA) package - 0.2 mm taller, 0.3 mm wider than SMBG | Compatible for board-level replacement if pad layout accommodates larger footprint; not drop-in due to dimensional mismatch | Select SMBJ6.0CA only when existing design uses SMB pads or requires slightly higher surge margin with identical electrical specs. |
| SMCJ6.0CA | Same VWM/VBR, but PPPM = 1500 W and VC = 10.3 V @ 143 A; SMC (DO-214AB) package - 2× footprint area of SMBG | Overqualified for most PCB space-constrained applications; used where >1 kV surge immunity is mandated (e.g., telecom central office) | Choose SMCJ6.0CA only when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board area permits larger package. |
Compared with SMBJ6.0CA and SMCJ6.0CA, SMBG6.0CA-M3/52 offers optimal balance of compact SMBG footprint, AEC-Q101 qualification, and halogen-free compliance - making it preferred for automotive and space-limited industrial designs where 600 W protection suffices.

FAQ
What does the "CA" suffix indicate in SMBG6.0CA-M3/52?
The "CA" suffix denotes a bidirectional configuration - meaning SMBG6.0CA-M3/52 provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., SMBG6.0A), it has no polarity marking and functions identically regardless of voltage polarity applied across its terminals, making it ideal for AC-coupled or floating signal lines.
Is SMBG6.0CA-M3/52 suitable for protecting 3.3 V logic circuits?
Yes, SMBG6.0CA-M3/52 is appropriate for 3.3 V logic protection when used with proper layout: its 6.0 V stand-off voltage (VWM) provides adequate margin above 3.3 V rail, and its 10.3 V clamping voltage (VC) limits transient overshoot to levels compatible with 3.3 V I/O tolerances (typically ±0.5 V beyond VDD). Confirm system-level clamping margin using worst-case VBR min (6.67 V) and layout parasitics.
How does the "M3" suffix affect SMBG6.0CA-M3/52 compliance and processing?
The "M3" suffix indicates SMBG6.0CA-M3/52 is halogen-free, RoHS-compliant, and qualified to JESD201 Class 2 whisker resistance. It meets IPC/JEDEC J-STD-020 MSL Level 1 (unlimited floor life, 260 °C reflow peak), enabling direct placement into standard lead-free reflow ovens without pre-baking - reducing manufacturing overhead versus moisture-sensitive alternatives.
What is the maximum operating temperature for SMBG6.0CA-M3/52?
SMBG6.0CA-M3/52 has a maximum junction temperature (TJ) of +150 °C and operates continuously from –55 °C to +150 °C. Its thermal resistance RθJA is 100 °C/W on standard 5 mm × 5 mm copper pads, so at 600 W peak power it requires careful thermal design - sustained average power must remain well below 0.6 W to avoid exceeding TJ limit in ambient temperatures above 85 °C.
Does SMBG6.0CA-M3/52 meet automotive qualification standards?
Yes, SMBG6.0CA-M3/52 is AEC-Q101 qualified - verified for automotive applications through stress tests including high-temperature reverse bias (HTRB), temperature cycling, and human-body-model ESD (≥8 kV). This qualification confirms its suitability for under-hood, infotainment, ADAS, and body electronics where reliability over 15 years and extreme thermal cycling are mandatory.
