Product details
Overview
SA13A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1.0 mA test current, 23.3 A peak pulse current (IPPM) under 10/1000 μs waveform, and clamps to ≤21.5 V at rated IPPM.
For engineers reviewing the SA13A-E3/54 datasheet, SA13A-E3/54 pinout, SA13A-E3/54 application, or SA13A-E3/54 equivalent, key selection criteria include its 500 W peak pulse power rating, AEC-Q101 qualification for automotive use, low 1.0 μA max reverse leakage at VWM, and glass passivated junction for stable clamping performance in industrial and sensor interface protection circuits.
Technical Context
The SA13A-E3/54 operates as a unidirectional avalanche diode with a cathode-marked DO-15 package. Its clamping behavior is defined by a 10/1000 μs surge waveform, delivering 21.5 V maximum clamping voltage at 23.3 A peak pulse current while maintaining 13 V nominal stand-off voltage.
It exhibits a temperature coefficient of +13 mV/°C for VBR and supports operating junction temperatures from –55 °C to +175 °C. The device is rated for 70 A non-repetitive forward surge current (IFSM) and dissipates up to 3.0 W on an infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse working voltage before clamping begins |
| VBR min/max | 14.4 V / 15.9 V at 1.0 mA - Confirmed avalanche onset range for reliable overvoltage triggering |
| VC @ IPPM | ≤21.5 V at 23.3 A - Clamping voltage during 10/1000 μs transient, limiting downstream stress |
| PPPM | 500 W - Peak surge energy absorption capability per single event |
| ID @ VWM | ≤1.0 μA - Low leakage ensures minimal standby power loss and signal integrity |
| TJ max | +175 °C - Enables operation in high-temperature engine bay or industrial control environments |
| IFSM | 70 A - Withstands short-duration inrush or fault currents without degradation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Same VWM (13 V), but SMC package (DO-214AB); 23.3 A IPPM, 21.5 V VC - identical electrical specs, smaller footprint | Surface-mount layout; not axial-leaded; requires PCB rework for DO-15 replacement | Select SMAJ13A when board space is constrained and reflow assembly is used. |
| P6KE13A | Same DO-15 package and VWM, but lower PPPM (600 W), higher VC (23.5 V), and higher ID (5.0 μA) | Higher clamping voltage reduces protection margin; suited for less sensitive loads or cost-sensitive designs | Choose P6KE13A only if 23.5 V clamping is acceptable and 600 W surge headroom is required. |
Compared with SMAJ13A and P6KE13A, the SA13A-E3/54 offers optimal balance of axial-leaded manufacturability, AEC-Q101 qualification, and tight 21.5 V clamping-making it preferred for automotive and industrial through-hole designs where reliability and proven surge margin are critical.

FAQ
What is the clamping voltage of SA13A-E3/54 at its rated peak pulse current?
The SA13A-E3/54 clamps to a maximum of 21.5 V at its rated peak pulse current of 23.3 A under the standard 10/1000 μs waveform. This value is measured per JEDEC standards and ensures predictable overvoltage limiting for downstream components such as microcontrollers and communication ICs. The clamping performance remains stable across its –55 °C to +175 °C operating junction temperature range.
Is SA13A-E3/54 qualified for automotive applications?
Yes, SA13A-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive electronic systems. The qualification includes stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life. Its DO-15 package with matte tin-plated leads meets JESD 22-B102 solderability requirements, supporting reliable assembly in automotive production environments.
What does the "E3/54" suffix indicate in SA13A-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance. The "/54" indicates the preferred package code for 13-inch diameter paper tape and reel packaging, with a base quantity of 4000 units per reel. This format enables automated pick-and-place handling while maintaining full traceability and compliance documentation.
How does SA13A-E3/54 differ from bidirectional variants like SA13CA?
SA13A-E3/54 is unidirectional with cathode marking and blocks reverse current until breakdown, whereas SA13CA is bidirectional with no polarity marking and clamps in both directions. SA13A-E3/54 has lower reverse leakage (1.0 μA vs. up to 2.0 μA for SA13CA) and is optimized for DC rail protection. Its VBR range (14.4–15.9 V) applies only in reverse bias, unlike SA13CA which specifies symmetric breakdown in both polarities.
Can SA13A-E3/54 be used in parallel for higher surge current handling?
No, SA13A-E3/54 should not be paralleled without external balancing resistors due to manufacturing variations in VBR that cause uneven current sharing. Uneven distribution may result in thermal runaway and premature failure of one device. For higher surge ratings, select a single higher-power TVS such as SA15A-E3/54 or consult Vishay's application note AN93 for derated parallel configurations with matched units and ballasting.
