Product details
Overview
SA13-E3/54 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 a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1.0 mA, 23.3 A peak pulse current (IPPM) under 10/1000 µs waveform, 500 W peak pulse power (PPPM), and clamps to ≤21.5 V at rated surge current - used in automotive body control modules to protect LIN bus transceivers from load-dump and inductive switching transients.
For engineers reviewing the SA13-E3/54 datasheet, SA13-E3/54 pinout, SA13-E3/54 application, or SA13-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC-compliant packaging details, AEC-Q101 qualification status, clamping performance curves, and direct alternatives for ESD/surge protection design-in across industrial and automotive electronics.
Technical Context
The SA13-E3/54 operates as a silicon avalanche diode with glass-passivated junction, optimized for fast response (<1 ps) to transient events and low incremental clamping resistance. Its uni-directional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until breakdown threshold is exceeded.
Rated for -55 °C to +175 °C junction temperature, it supports high-reliability applications requiring sustained operation under thermal stress. The device meets JESD22-B106 solder dip (275 °C, 10 s) and JESD201 Class 1A whisker resistance, confirming robustness in automated assembly and harsh-environment deployment.
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 |
|---|---|---|---|
| SMAJ13A-E3/52 (Vishay) | Same VWM/VBR, but SMA package (DO-214AC); 20% smaller footprint, 40% lower thermal resistance. | Better suited for space-constrained SMT layouts; requires rework of pad stack and stencil design. | Select if board real estate is limited and thermal management prioritizes PCB copper area over axial lead routing. |
| P6SMB13A (Littelfuse) | Identical VWM (13 V), VBR (14.4–15.9 V), and PPPM (500 W); DO-214AA package with slightly higher VC (22.5 V). | Compatible with same surge standards but exhibits 1 V higher clamping, requiring margin check on protected IC's absolute max rating. | Choose when dual-sourcing is required and minor clamping voltage increase is acceptable for legacy design reuse. |

FAQ
What is the maximum clamping voltage of SA13-E3/54 at its rated peak pulse current?
The SA13-E3/54 clamps to a maximum of 21.5 V when subjected to its rated 23.3 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 7 in Vishay Document 88378 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring compatibility with 24 V-rated interface ICs.
Is SA13-E3/54 qualified to AEC-Q101, and what tests does that include?
Yes, SA13-E3/54 is AEC-Q101 qualified per Vishay documentation. This includes high-temperature operating life (HTOL) at 175 °C for 1000 hours, temperature cycling (TCT) from -55 °C to +150 °C for 1000 cycles, and human-body-model ESD testing ≥8 kV - validating its suitability for automotive powertrain and body electronics without additional qualification effort.
What is the meaning of the "E3/54" suffix in SA13-E3/54?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD201 Class 1A whisker resistance; "/54" denotes the preferred package code for 13-inch paper tape and reel packaging containing 4000 units. This ordering format aligns with Vishay's standard logistics coding and confirms full compliance with JEDEC and RoHS material restrictions.
Can SA13-E3/54 be used in bi-directional protection applications?
No, SA13-E3/54 is strictly a uni-directional TVS diode, as confirmed by its part number suffix "A" (not "CA") and specified polarity marking (cathode band). For bi-directional protection at 13 V standoff, the correct variant is SA13CA-E3/54 - which has symmetric breakdown in both directions and no polarity marking.
What is the thermal resistance from junction to leads (RθJL) for SA13-E3/54?
Vishay specifies a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W for the DO-204AC package used in SA13-E3/54, derived from steady-state power derating data in Figure 5 of Document 88378. This value assumes 0.375 inch (9.5 mm) lead length and enables accurate thermal modeling when mounted on FR-4 with minimal copper pour.
