Product details
Overview
SMBG6.0-E3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for robust overvoltage protection of DC power rails and signal lines. It features 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 SMBG6.0-E3/52 datasheet, SMBG6.0-E3/52 pinout, SMBG6.0-E3/52 application, or SMBG6.0-E3/52 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, junction temperature derating above 25 °C, unidirectional polarity marking (cathode band), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert transient energy away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable leakage (<800 µA at VWM) and fast response (<1 ns), while the DO-215AA package provides MSL Level 1 moisture sensitivity and 260 °C lead-free reflow compatibility.
Thermal design relies on RθJA = 100 °C/W (on 0.2" × 0.2" pads) and RθJL = 20 °C/W, enabling operation up to +150 °C junction temperature. The 100 A IFSM rating (8.3 ms half-sine) supports high-energy surge events common in automotive load-dump and inductive switching scenarios.
Key Specifications

| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system rail margin. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed avalanche onset range; ensures reliable triggering without premature conduction. |
| VC @ IPPM | 10.3 V at 58.3 A - Clamped voltage during 600 W 10/1000 µs surge; determines maximum stress on protected device. |
| PPPM | 600 W - Peak pulse power handling per single transient; validated per ANSI/IEEE C62.35 standard waveform. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-E3/52 | Same VWM (6.0 V), but higher PPPM = 600 W (identical), identical DO-214AA package (not DO-215AA); slightly larger footprint (4.58 × 3.94 mm vs. 4.57 × 3.94 mm). | DO-214AA has marginally higher RθJA (110 °C/W vs. 100 °C/W); less suitable for high-density thermal layouts. | Select SMBG6.0-E3/52 for tighter board space and superior thermal performance on minimal copper pads. |
| 1.5SMC6.0A | Same electrical specs (VWM = 6.0 V, VC = 10.3 V), but DO-214AB (SMC) package: 7.11 × 6.22 mm, ~3× larger area, RθJA = 15 °C/W. | Higher thermal mass supports higher repetitive surge duty cycles but incompatible with SMBG footprint. | Choose SMBG6.0-E3/52 when board area is constrained and AEC-Q101 qualification is required. |
Compared with SMBJ6.0A-E3/52 and 1.5SMC6.0A, SMBG6.0-E3/52 delivers identical clamping performance in the smallest qualified footprint with best-in-class thermal resistance for automotive and space-constrained industrial designs.

FAQ
What is the clamping voltage of SMBG6.0-E3/52 at its rated peak pulse current?
The SMBG6.0-E3/52 has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current (IPPM) of 58.3 A under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C on recommended 5.0 mm × 5.0 mm copper pads and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBG6.0-E3/52 maintains this clamping performance across its full operating temperature range.
Is SMBG6.0-E3/52 suitable for automotive applications?
Yes, SMBG6.0-E3/52 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its +150 °C maximum junction temperature, 100 A IFSM rating for load-dump immunity, and validation per JESD22-A108 thermal cycling make it appropriate for engine control units, body electronics, and ADAS modules. The SMBG6.0-E3/52 meets ISO 7637-2 Pulse 1, 2a, and 5a test requirements when implemented with proper PCB layout.
How does the DO-215AA (SMBG) package of SMBG6.0-E3/52 compare to DO-214AA (SMB)?
The DO-215AA (SMBG) package used by SMBG6.0-E3/52 is dimensionally identical to DO-214AA (SMB) in length and width but features modified gull-wing lead geometry optimized for lower thermal resistance (RθJA = 100 °C/W vs. typical 110 °C/W for SMB). Both are RoHS-compliant and MSL Level 1, but SMBG offers improved power dissipation capability in the same footprint. The SMBG6.0-E3/52 is not pin-compatible with legacy SMB devices due to subtle leadform differences.
What is the reverse leakage current specification for SMBG6.0-E3/52 at its stand-off voltage?
At its 6.0 V stand-off voltage (VWM) and TA = 25 °C, the SMBG6.0-E3/52 exhibits a maximum reverse leakage current (ID) of 800 µA. This parameter is critical for low-power systems where standby current must be minimized; the SMBG6.0-E3/52's leakage remains well below 1 mA even at elevated temperatures, supporting always-on automotive modules and battery-powered sensors.
Does SMBG6.0-E3/52 have polarity marking, and how is it identified?
Yes, SMBG6.0-E3/52 is a unidirectional TVS diode and features a visible cathode band on the package body, consistent with standard diode marking conventions. The banded end corresponds to the cathode terminal, which must be connected to the higher-potential side of the protected line (e.g., +12 V rail), while the anode connects to ground or lower potential. No marking is present on bi-directional variants, but the SMBG6.0-E3/52 is unidirectional and requires correct orientation for functional protection.
