Product details
Overview
SA8.0HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 8.0 V stand-off voltage (VWM), 8.89–9.83 V breakdown voltage (VBR) at 1 mA, 13.6 V maximum clamping voltage (VC) at 25 A peak pulse current, 500 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive use.
For engineers reviewing the SA8.0HE3/54 datasheet, SA8.0HE3/54 pinout, SA8.0HE3/54 application, or SA8.0HE3/54 equivalent, this device is selected for robust ESD and surge protection in automotive body control modules, industrial sensor interfaces, and 12 V supply rail conditioning where low clamping voltage and high surge reliability are critical.
Technical Context
This TVS diode operates as a shunt-clamping protector: under normal conditions it presents high impedance (>600 μA leakage at 8.0 V), but triggers into low-impedance conduction when transient voltage exceeds VBR, clamping the protected node to ≤13.6 V at 25 A. Its glass-passivated junction ensures stable breakdown and fast response (<1 ns).
Rated for -55 °C to +175 °C junction temperature, it supports high-reliability automotive environments. The HE3 suffix confirms AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and RoHS compliance - distinguishing it from commercial-grade E3 variants.
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 |
|---|---|---|---|
| SMAJ8.0AHE3/A | Same VWM/VBR/VC specs, but SMC (DO-214AB) surface-mount package; 600 W PPPM. | Requires PCB re-layout; better suited for high-density automotive PCBs where axial leads are impractical. | Select SMAJ8.0AHE3/A when space-constrained layouts or automated assembly mandate SMT packaging. |
| SA8.0A-E3/54 | Identical electrical specs and DO-204AC package, but commercial-grade (E3) - no AEC-Q101 or JESD 201 Class 2 qualification. | Limited to non-automotive industrial or consumer applications where automotive reliability standards are not mandated. | Choose SA8.0A-E3/54 only for cost-sensitive, non-automotive designs where qualification traceability is not required. |

FAQ
What is the clamping voltage of SA8.0HE3/54 at its rated peak pulse current?
The SA8.0HE3/54 has a maximum clamping voltage (VC) of 13.6 V when subjected to its rated peak pulse current of 25 A using the standard 10/1000 μs waveform. This value is measured per Figure 7 in the Vishay datasheet 88378 and defines the upper voltage limit imposed on protected circuits during surge events. Maintaining VC ≤13.6 V ensures compatibility with 5 V and 3.3 V logic interfaces downstream.
Is SA8.0HE3/54 suitable for automotive applications?
Yes, SA8.0HE3/54 is explicitly qualified to AEC-Q101 and carries the HE3 suffix denoting automotive-grade construction, including JESD 201 Class 2 whisker resistance and RoHS compliance. It is specified for operation from -55 °C to +175 °C and used in production automotive systems such as body control modules, lighting drivers, and sensor interfaces where reliability under thermal and mechanical stress is critical.
How does SA8.0HE3/54 differ from SA8.0A-E3/54?
SA8.0HE3/54 and SA8.0A-E3/54 share identical electrical parameters (VWM, VBR, VC, PPPM) and DO-204AC packaging, but SA8.0HE3/54 adds AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - verified via accelerated stress testing. SA8.0A-E3/54 is commercial-grade and lacks automotive traceability, limiting its use to non-automotive applications.
What is the maximum reverse leakage current for SA8.0HE3/54 at its stand-off voltage?
At its rated stand-off voltage (VWM) of 8.0 V and ambient temperature of 25 °C, SA8.0HE3/54 exhibits a maximum reverse leakage current (ID) of 25 μA. This low leakage ensures minimal power loss in standby mode and avoids false triggering in high-impedance sensing circuits, as confirmed in Table "ELECTRICAL CHARACTERISTICS" on page 2 of Vishay document 88378.
Can SA8.0HE3/54 be used for bi-directional transient protection?
No, SA8.0HE3/54 is a uni-directional TVS diode, indicated by the "A" suffix (not "CA"). It conducts only when cathode voltage exceeds anode voltage by ≥VBR. For bi-directional protection - such as AC lines or data buses requiring symmetrical clamping - a part like SA8.0CAHE3/54 would be required, which has matched breakdown in both polarities and no polarity marking.
