Product details
Overview
SMBG60A-M3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMBG (DO-215AA) package, rated for 60 V standoff voltage, 66.7–73.7 V breakdown at 1 mA, 96.8 V clamping at 6.2 A peak pulse current, and 600 W peak pulse power with 10/1000 μs waveform-designed to protect MOSFETs and signal lines in automotive powertrain control units.
For engineers reviewing the SMBG60A-M3/5B datasheet, SMBG60A-M3/5B pinout, SMBG60A-M3/5B application, or SMBG60A-M3/5B equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, halogen-free RoHS compliance, 150 °C max junction temperature, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a clamping-type overvoltage protector: under normal bias it presents high impedance (>1 μA leakage at 60 V), then rapidly transitions to low-impedance conduction when transient voltage exceeds VBR, limiting downstream voltage to ≤96.8 V during 10/1000 μs surges. Its glass-passivated junction ensures stable avalanche characteristics and long-term reliability under repetitive transients.
The SMBG60A-M3/5B is thermally optimized for surface-mount use with RθJA = 100 °C/W (on 5.0 mm × 5.0 mm pads) and RθJL = 20 °C/W, enabling effective heat dissipation in compact automotive and industrial PCB layouts without heatsinking-critical for sustained operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 48 V nominal systems. |
| VBR @ IT = 1 mA | 66.7–73.7 V - Measured breakdown range confirming tight tolerance for predictable turn-on behavior across production lots. |
| VC @ IPPM = 6.2 A | 96.8 V - Clamped voltage during 10/1000 μs surge; determines maximum stress imposed on protected ICs or MOSFETs. |
| PPPM | 600 W - Peak pulse power handling capacity; supports robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges. |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); enables survival of high-energy load-dump events in 12/24 V vehicle systems. |
| TJ max | +150 °C - Maximum junction temperature; allows deployment in under-hood automotive environments without derating. |
| Package | SMBG (DO-215AA) - Low-profile surface-mount outline with 0.235–0.255 inch body length; compatible with standard SMT reflow profiles and J-STD-020 MSL Level 1. |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, gull-wing leadform, matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102. Polarity indicated by cathode band; anode and cathode terminals are electrically isolated except during avalanche conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | High-side connection point for reverse-biased TVS operation | Connected to protected line (e.g., battery rail or signal trace); conducts surge current toward ground when VIN > VBR. |
| Anode | Low-side reference terminal | Typically tied to system ground or low-impedance return path; completes clamping loop during transient events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBG60A-E3/5B | Same electrical specs but RoHS-compliant with brominated flame retardant (non-halogen-free); MSL Level 1, same SMBG package. | Approved for industrial-grade (non-automotive) designs where halogen-free requirement is not mandated. | Select SMBG60A-E3/5B for cost-sensitive industrial applications without AEC-Q101 or halogen-free mandates. |
| SMBG60AHM3/5B | Identical electrical and thermal specs, but AEC-Q101 qualified and halogen-free (HM3 suffix); same SMBG package. | Required for automotive safety-critical subsystems needing full AEC-Q101 + halogen-free compliance. | Choose SMBG60AHM3/5B when qualifying for ASIL-C systems or Tier 1 automotive supply chains requiring dual certification. |
Compared with SMBG60A-M3/5B, SMBG60A-E3/5B lacks halogen-free status and AEC-Q101 qualification, while SMBG60AHM3/5B adds AEC-Q101 validation-making SMBG60A-M3/5B the optimal balance of automotive qualification, halogen-free compliance, and broad industrial applicability.

FAQ
What is the clamping voltage of SMBG60A-M3/5B at its rated peak pulse current?
The SMBG60A-M3/5B has a maximum clamping voltage (VC) of 96.8 V at 6.2 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBG60A-M3/5B maintains this clamping performance across its full operating temperature range of –55 °C to +150 °C.
Is SMBG60A-M3/5B suitable for automotive applications?
Yes, SMBG60A-M3/5B is AEC-Q101 qualified and rated for junction temperatures up to +150 °C, making it suitable for under-hood automotive applications including engine control units, transmission control modules, and ADAS power supplies. Its halogen-free (M3) construction and MSL Level 1 rating further support automotive manufacturing requirements. The SMBG60A-M3/5B meets ISO 7637-2 Pulse 1/2a/5a immunity thresholds when properly mounted on 5.0 mm × 5.0 mm copper pads.
What does the "M3" suffix indicate in SMBG60A-M3/5B?
The "M3" suffix in SMBG60A-M3/5B denotes halogen-free, RoHS-compliant construction meeting JEDEC J-STD-201 Class 2 whisker resistance, alongside industrial-grade reliability. It distinguishes the part from "E3" (RoHS-compliant but not halogen-free) and "HM3" (AEC-Q101 qualified + halogen-free). The SMBG60A-M3/5B retains full AEC-Q101 qualification despite the M3 designation, as confirmed in Vishay's official documentation.
How is SMBG60A-M3/5B mounted and what PCB layout is recommended?
SMBG60A-M3/5B uses gull-wing leads in SMBG (DO-215AA) package and is designed for reflow soldering on standard SMT lines. Vishay specifies mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated thermal resistance (RθJA = 100 °C/W) and 600 W pulse power capability. The SMBG60A-M3/5B requires no thermal vias for basic operation but benefits from internal ground planes for enhanced surge dissipation in high-reliability designs.
Does SMBG60A-M3/5B have bidirectional capability?
No, SMBG60A-M3/5B is a unidirectional Transient Voltage Suppressor, identified by the "A" (not "CA") suffix. It conducts only during reverse-bias overvoltage events, with cathode marked by a band. For bidirectional protection, Vishay offers SMBG60CA-M3/5B, which provides symmetrical clamping in both polarities. The SMBG60A-M3/5B must be oriented correctly in-circuit with cathode toward the protected line and anode to ground.
