Product details
Overview
SMBG5.0AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) diode designed for primary overvoltage protection of sensitive electronics. It features a 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), and clamps transients to ≤9.2 V at 65.2 A. It is AEC-Q101 qualified and used in automotive sensor signal lines and power rails.
For engineers reviewing the SMBG5.0AHE3/5B datasheet, SMBG5.0AHE3/5B pinout, SMBG5.0AHE3/5B application, or SMBG5.0AHE3/5B equivalent, key selection criteria include unidirectional polarity, DO-215AA (SMBG) package compatibility, 150 °C max junction temperature, and compliance with UL 497B for surge protector classification.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, conducting only when reverse voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<800 µA at VWM). The device responds in <1 ns to fast transients and maintains low incremental surge resistance for effective energy diversion.
Thermal performance is defined by RθJA = 100 °C/W (on 0.2" × 0.2" copper pads) and RθJL = 20 °C/W, enabling reliable operation up to 150 °C junction temperature. It meets MSL Level 1 per J-STD-020 and supports reflow soldering with peak temperature up to 260 °C.
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 |
|---|---|---|---|
| SMBJ5.0A-E3/5B | Same SMB (DO-214AA) package but lower 400 W PPPM; VBR 6.4–7.0 V; no AEC-Q101 qualification. | Limited to non-automotive industrial or consumer use where 600 W surge headroom is not required. | Select when cost sensitivity outweighs automotive qualification and higher surge margin. |
| SMCJ5.0AHE3/5B | Same AEC-Q101 qualification and 600 W rating, but larger SMC (DO-214AB) package; VBR 6.4–7.07 V. | Requires more PCB area; better thermal dissipation for sustained surge duty cycles. | Choose when board layout allows larger footprint and enhanced thermal margin is prioritized over space-constrained designs. |

FAQ
What is the clamping voltage of SMBG5.0AHE3/5B at its rated peak pulse current?
The SMBG5.0AHE3/5B clamps to a maximum of 9.2 V at its specified peak pulse current of 65.2 A (10/1000 µs waveform). This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The SMBG5.0AHE3/5B maintains this clamping performance across its full operating temperature range and lifetime, supporting robust system-level surge immunity design.
Is SMBG5.0AHE3/5B suitable for automotive applications?
Yes, SMBG5.0AHE3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood sensor protection and body electronics. Its construction-glass-passivated junction, MSL Level 1 rating, and 150 °C maximum junction temperature-meets stringent automotive reliability requirements. The SMBG5.0AHE3/5B also carries UL 497B recognition, further validating its suitability for safety-critical vehicle subsystems.
What does the 'HE3' suffix indicate in SMBG5.0AHE3/5B?
The 'HE3' suffix in SMBG5.0AHE3/5B denotes RoHS-compliant construction with AEC-Q101 qualification. 'H' indicates AEC-Q101 qualification, 'E3' specifies RoHS compliance and industrial-grade reliability. This distinguishes it from base variants like 'E3' (RoHS, non-automotive) or 'HM3' (halogen-free + AEC-Q101). The '5B' denotes 13-inch tape-and-reel packaging with 3200 units per reel.
How does SMBG5.0AHE3/5B differ from SMBJ5.0A-E3/5B?
SMBG5.0AHE3/5B offers 600 W peak pulse power in the smaller DO-215AA (SMBG) package and carries AEC-Q101 qualification, whereas SMBJ5.0A-E3/5B provides only 400 W in the DO-214AA (SMB) package and lacks automotive qualification. Both share similar VWM (5.0 V) and VBR (6.4–7.07 V), but the SMBG5.0AHE3/5B delivers higher surge headroom and certified reliability for mission-critical applications.
What is the maximum reverse leakage current for SMBG5.0AHE3/5B at its stand-off voltage?
The SMBG5.0AHE3/5B exhibits a maximum reverse leakage current (ID) of 800 µA at its 5.0 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage ensures minimal power loss and signal integrity impact in always-on circuits such as automotive sensor bias networks or industrial 4–20 mA loop interfaces. The SMBG5.0AHE3/5B maintains leakage below 1 mA across its full -55 °C to +150 °C operating range.
