Product details
Overview
SA10A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor diode in DO-15 package, rated for 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 μs), 29.4 A peak pulse current (IPPM), and 17.0 V clamping voltage (VC) at IPPM. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the SA10A-E3/54 datasheet, SA10A-E3/54 pinout, SA10A-E3/54 application, or SA10A-E3/54 equivalent, this page delivers verified electrical parameters, DO-15 terminal mapping, AEC-Q101 qualification status, clamping performance under 10/1000 μs surge, and direct alternatives for overvoltage protection design.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device that remains high-impedance below 10 V (VWM) and rapidly transitions to low-impedance conduction above its 11.1–12.3 V breakdown threshold. Its glass-passivated junction enables sub-nanosecond response to ESD and lightning-induced surges.
Designed for repetitive transient suppression with 0.01% duty cycle, it sustains 500 W peak pulse power per 10/1000 μs waveform and dissipates 3.0 W continuously on an infinite heatsink at TL = 75 °C. The 175 °C maximum junction temperature supports operation in automotive engine control units and industrial motor drives.

IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp on 3.3 V or 5 V digital signal paths to prevent false resets or erroneous ADC readings. Use Value: Fast response time and tight VBR tolerance (±5.4%) ensure consistent triggering without nuisance tripping during normal operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same VWM (10 V), lower PPPM (400 W), SMA package (surface-mount) | Requires PCB redesign for SMT vs. DO-15 through-hole; better for space-constrained designs | Select SMAJ10A when board real estate is limited and automated assembly is preferred |
| P6SMB10A | Same VWM (10 V), identical DO-15 package, 600 W PPPM rating | Higher surge margin but slightly higher VC (18.2 V); suitable where clamping headroom permits | Select P6SMB10A when enhanced surge endurance is required without changing layout |
Compared with SA10A-E3/54, SMAJ10A offers surface-mount compatibility at reduced power handling, while P6SMB10A provides higher 600 W surge rating in the same DO-15 footprint-enabling drop-in upgrades where clamping voltage margin allows.

FAQ
What is the clamping voltage of SA10A-E3/54 at its rated peak pulse current?
The SA10A-E3/54 has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 29.4 A under a 10/1000 μs waveform. This value is measured per the test conditions specified in Vishay document 88378 and ensures downstream ICs experience controlled overvoltage stress during surge events. The SA10A-E3/54 maintains this clamping performance across its qualified operating temperature range.
Is SA10A-E3/54 suitable for automotive applications?
Yes, SA10A-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications such as engine control units, body electronics, and infotainment power rails. Its DO-15 package, 175 °C maximum junction temperature, and validated performance under temperature cycling, HTRB, and ESD testing meet automotive reliability requirements. The SA10A-E3/54 is explicitly listed in Vishay's AEC-Q101 qualified product list per revision 27-Sep-2021.
What does the "E3/54" suffix mean in SA10A-E3/54?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "/54" denotes the preferred package code for 13-inch paper tape and reel packaging with a base quantity of 4000 units. This ordering format aligns with Vishay's standardized delivery mode for DO-15 devices and ensures compatibility with standard pick-and-place and through-hole assembly lines. SA10A-E3/54 is not AEC-Q101 qualified unless specified as HE3.
How does SA10A-E3/54 compare to bidirectional variants like SA10CA?
SA10A-E3/54 is unidirectional and features a cathode band for polarity-sensitive placement, whereas SA10CA is bidirectional with no polarity marking and symmetric clamping in both directions. SA10A-E3/54 exhibits forward conduction behavior below VBR, making it appropriate for DC rail protection; SA10CA suits AC-coupled or floating signal lines. Their VWM (10 V), VBR (11.1–12.3 V), and PPPM (500 W) are identical, but SA10A-E3/54 supports 70 A IFSM, unlike SA10CA.
What is the maximum leakage current of SA10A-E3/54 at its stand-off voltage?
The SA10A-E3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its rated stand-off voltage (VWM) of 10 V and TA = 25 °C. This ultra-low leakage preserves power efficiency in battery-backed systems and prevents false triggering in high-impedance sensor interfaces. Leakage remains within specification across the full operating temperature range of –55 °C to +175 °C, as confirmed in Vishay document 88378.
