Product details
Overview
SA5.0A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of sensitive electronics. It features 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 500 W peak pulse power (10/1000 μs), clamping voltage of 9.2 V at 54.3 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA5.0A-E3/54 datasheet, SA5.0A-E3/54 pinout, SA5.0A-E3/54 application, or SA5.0A-E3/54 equivalent, key selection criteria include its unidirectional polarity, DO-15 mechanical form factor, 600 μA max reverse leakage at VWM, 3.0 W steady-state power dissipation, and suitability for I/O line and DC power rail surge suppression in harsh environments.
Technical Context
The SA5.0A-E3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling fast response (<1 ns) to transient events such as ESD, lightning-induced surges, and inductive switching spikes. Its unidirectional configuration provides forward conduction path while clamping reverse transients above VBR.
It complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and ISO 7637-2 (automotive load dump) when applied with appropriate series impedance. Thermal performance is defined by 175 °C max junction temperature and derating curves for both pulse and steady-state conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Same VWM/VBR range but in SMA (DO-214AC) surface-mount package; 400 W PPPM | Requires PCB layout change; better suited for high-density automated assembly | Select SMAJ5.0A when board space is constrained and SMT process is mandatory. |
| P6KE5.0A | Higher PPPM (600 W), same DO-15 package, but larger VC (13.4 V) and wider VBR tolerance (6.4–8.2 V) | Less precise clamping; acceptable where protected IC has higher VDD margin | Choose P6KE5.0A only if system-level testing confirms 13.4 V clamping remains within safe operating area. |
Compared with SMAJ5.0A and P6KE5.0A, the SA5.0A-E3/54 offers tighter VBR tolerance (±5.5 %), lower clamping voltage (9.2 V), and AEC-Q101 qualification-making it preferred for automotive and precision 5 V rail protection where reliability and voltage margin are critical.

FAQ
What is the maximum clamping voltage of the SA5.0A-E3/54 under specified test conditions?
The SA5.0A-E3/54 exhibits a maximum clamping voltage (VC) of 9.2 V when subjected to its rated peak pulse current (IPPM = 54.3 A) using the standard 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on the protected circuit during worst-case transient events. The SA5.0A-E3/54 maintains this clamping performance across its full operational temperature range, with minor derating per Vishay's published curves.
Is the SA5.0A-E3/54 suitable for automotive applications?
Yes, the SA5.0A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-including glass-passivated junction, DO-15 package with matte tin leads, and 175 °C maximum junction temperature-meets stringent automotive reliability requirements. The SA5.0A-E3/54 is commonly deployed in body control modules, infotainment power supplies, and sensor interface circuits where ISO 7637-2 compliance and long-term stability are mandatory.
How does the SA5.0A-E3/54 differ from bidirectional variants like SA5.0CA?
The SA5.0A-E3/54 is unidirectional, meaning it conducts only in forward bias and clamps reverse transients, with polarity marked by a cathode band. In contrast, SA5.0CA is bidirectional and symmetrical-clamping in both directions with no polarity marking. The SA5.0A-E3/54 has lower leakage at VWM and is preferred for DC power rail protection, whereas SA5.0CA suits AC signal lines or floating buses. Their VBR and VC values differ slightly due to structural asymmetry.
What is the reverse leakage current specification for the SA5.0A-E3/54 at rated stand-off voltage?
At its rated stand-off voltage (VWM = 5.0 V) and TA = 25 °C, the SA5.0A-E3/54 specifies a maximum reverse leakage current (ID) of 600 μA. This low leakage ensures minimal impact on power efficiency and signal integrity in always-on circuits. Leakage increases with temperature and voltage stress, remaining within design-safe limits up to 125 °C per Vishay's derating data.
Can the SA5.0A-E3/54 be used in parallel for higher surge current handling?
No-parallel connection of SA5.0A-E3/54 devices is not recommended due to mismatch in VBR and dynamic impedance, which causes uneven current sharing and potential thermal runaway. For higher surge capacity, select a single higher-rated device (e.g., SA6.0A or SA6.5A) or implement staged protection with upstream current limiting. The SA5.0A-E3/54 is characterized and validated for standalone operation per its published IPPM rating.
