Product details
Overview
SMBG6.0-E3/5B 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), and clamps transients to ≤10.3 V at 58.3 A. It is widely deployed in automotive ECUs and industrial sensor interfaces where fast response and AEC-Q101 reliability are required.
For engineers reviewing the SMBG6.0-E3/5B datasheet, SMBG6.0-E3/5B pinout, SMBG6.0-E3/5B application, or SMBG6.0-E3/5B equivalent, key selection criteria include unidirectional polarity, 10.3 V clamping voltage at rated surge current, RoHS-compliant matte tin terminals, MSL Level 1 reflow compatibility, and qualification per AEC-Q101 for automotive-grade deployment.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (>800 µA leakage at 6.0 V), but triggers into low-impedance conduction when transient voltage exceeds its 6.67–7.37 V breakdown range. Its glass-passivated junction ensures stable VBR tolerance and low incremental surge resistance.
Designed for 10/1000 µs waveform compliance, it delivers 58.3 A peak pulse current with ≤10.3 V clamping, enabling effective suppression of inductive switching spikes and ESD events. Thermal resistance is 100 °C/W (junction-to-ambient) on standard 5.0 mm × 5.0 mm copper pads, supporting sustained operation up to 150 °C junction temperature.
Key Specifications

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), identical VBR range, but lower PPPM = 400 W and IPPM = 38.9 A | Not qualified to AEC-Q101; intended for commercial-grade consumer/industrial use only | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom is unnecessary |
| SMBG6.0AHE3/5B | Identical electrical specs and DO-215AA package; differs only in AEC-Q101 qualification suffix (HE3 vs E3) | Same automotive use cases; HE3 denotes full AEC-Q101 compliance documentation package | Prefer SMBG6.0AHE3/5B when formal PPAP submission or automotive OEM audit traceability is required |
Compared with SMBJ6.0A-E3/52, SMBG6.0-E3/5B provides higher surge robustness and automotive qualification; versus SMBG6.0AHE3/5B, it shares all performance parameters but lacks the formal AEC-Q101 certification documentation bundle-making it suitable for automotive-adjacent industrial designs where full PPAP is not mandated.

FAQ
What is the clamping voltage of SMBG6.0-E3/5B at its rated peak pulse current?
The SMBG6.0-E3/5B clamps to a maximum of 10.3 V at its rated peak pulse current of 58.3 A (10/1000 µs waveform). This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBG6.0-E3/5B maintains this clamping performance across its operational temperature range, ensuring predictable protection behavior in automotive and industrial applications.
Is SMBG6.0-E3/5B suitable for automotive applications?
Yes, SMBG6.0-E3/5B is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and ADAS sensor modules. Its 150 °C maximum junction temperature, glass-passivated junction, and MSL Level 1 reflow compatibility meet stringent automotive manufacturing and field reliability requirements. The SMBG6.0-E3/5B has undergone accelerated stress testing per AEC-Q101, confirming suitability for under-hood and chassis-mounted deployments.
What does the "-E3/5B" suffix indicate in SMBG6.0-E3/5B?
The "-E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD201 Class 1A whisker resistance. The "/5B" specifies packaging: 3200 units per 13-inch diameter plastic tape-and-reel. This format supports high-speed automated placement and is compatible with standard SMT feeders. The SMBG6.0-E3/5B is distinct from HE3-suffixed variants, which include full AEC-Q101 documentation packages.
How does SMBG6.0-E3/5B differ from SMBJ6.0A-E3/52?
SMBG6.0-E3/5B offers 600 W peak pulse power and 58.3 A IPPM, whereas SMBJ6.0A-E3/52 is rated for 400 W and 38.9 A. Additionally, SMBG6.0-E3/5B is AEC-Q101 qualified; SMBJ6.0A-E3/52 is commercial-grade only. Both share identical VWM (6.0 V) and VBR range, but the SMBG6.0-E3/5B's higher surge rating and automotive qualification make it appropriate for demanding environments where the SMBG6.0-E3/5B's enhanced robustness is required.
What is the thermal resistance of SMBG6.0-E3/5B, and how does it affect layout design?
The SMBG6.0-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value guides PCB layout: adequate copper area must be provided to maintain TJ ≤ 150 °C under worst-case surge duty cycles. For high-reliability applications, designers should follow Vishay's recommended pad layout in the SMBG datasheet to ensure the SMBG6.0-E3/5B achieves its rated thermal and electrical performance.
