Product details
Overview
SA13AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for circuit protection against ESD and surge transients. It features 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 μs), 23.3 A peak pulse current (IPPM), and clamps to ≤21.5 V at rated current. Used in automotive power line and sensor interface protection per AEC-Q101 qualification.
For engineers reviewing the SA13AHE3/54 datasheet, SA13AHE3/54 pinout, SA13AHE3/54 application, or SA13AHE3/54 equivalent, this page delivers verified electrical specs, DO-15 terminal mapping, bidirectional/unidirectional polarity context, AEC-Q101 qualification status, and real-world clamping performance data for robust overvoltage design validation.
Technical Context
The SA13AHE3/54 operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast response (<1 ns) to transient events. Its 13 V stand-off rating allows reliable blocking during normal operation while triggering conduction above ~14.4 V to divert surge energy.
It sustains 70 A non-repetitive forward surge current (IFSM) and maintains clamping voltage ≤21.5 V at 23.3 A IPPM under 10/1000 μs waveform - critical for protecting downstream MOSFETs and ICs in 12 V automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse voltage before leakage exceeds 1 μA; defines operating margin below breakdown |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - guaranteed avalanche initiation range; ensures predictable turn-on across temperature and unit variation |
| VC @ IPPM | ≤21.5 V at 23.3 A - clamping voltage under 10/1000 μs surge; determines protected device's maximum stress level |
| PPPM | 500 W - peak transient power handling capability; enables protection against IEC 61000-4-5 Level 3 surges |
| IFSM | 70 A - single half-sine surge current rating (10 ms); supports load-dump immunity in automotive 12 V rails |
| TJ max | +175 °C - maximum junction temperature; enables use in under-hood automotive environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/52 | Same VWM/VBR/PPPM but SMA package (surface-mount); lower IFSM (40 A) and no AEC-Q101 qualification | Preferred for space-constrained PCBs where reflow compatibility is required over through-hole ruggedness | Select SMAJ13A-E3/52 only if board area and assembly process favor SMT over axial DO-15 mounting |
| P6KE13A | Same DO-15 package and 13 V rating, but 600 W PPPM and higher VC (25.0 V); not AEC-Q101 qualified | Suitable for industrial mains-input protection where higher clamping voltage is acceptable | Choose P6KE13A only when higher surge margin outweighs need for tighter clamping and automotive qualification |
Compared with SMAJ13A-E3/52 and P6KE13A, the SA13AHE3/54 uniquely combines AEC-Q101 qualification, 21.5 V clamping ceiling, and 70 A surge current capability in a through-hole DO-15 package - making it the preferred choice for production automotive modules requiring long-term reliability and validated test compliance.

FAQ
What is the clamping voltage of SA13AHE3/54 at its rated peak pulse current?
The SA13AHE3/54 has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPPM) of 23.3 A under a 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that downstream components see no more than 21.5 V during a defined surge event - a key parameter for validating protection margins in 12 V automotive systems where SA13AHE3/54 is commonly deployed.
Is SA13AHE3/54 suitable for automotive applications?
Yes, SA13AHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junction, matte tin-plated leads compliant with J-STD-002, and qualification across temperature cycling, high-temperature reverse bias, and ESD tests. The SA13AHE3/54 is specified for operation from –55 °C to +175 °C, supporting under-hood deployment in engine control units and body electronics modules.
What does the "HE3" suffix indicate in SA13AHE3/54?
The "HE3" suffix in SA13AHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this variant from the commercial-grade "E3" version (e.g., SA13A-E3/54), confirming enhanced reliability testing and plating robustness required for automotive production. The "54" refers to the preferred packaging code: 4000-piece 13-inch paper tape and reel.
How does SA13AHE3/54 differ from bidirectional TVS diodes like SA13CA?
The SA13AHE3/54 is unidirectional and features a cathode band for polarity-sensitive placement, whereas SA13CA is bidirectional with no marking and symmetrical clamping in both directions. SA13AHE3/54 offers lower forward voltage (VF = 3.5 V at 100 A) and higher IFSM (70 A), making it optimal for DC power rail protection. SA13CA is used where AC-coupled or dual-polarity transients dominate, such as telecom line interfaces.
What is the thermal derating behavior of SA13AHE3/54 above 25 °C ambient?
SA13AHE3/54 follows a linear derating curve from 100 % power at 25 °C to 0 % at 175 °C junction temperature. Its steady-state power dissipation (PD) drops from 3.0 W at TL = 75 °C to zero at TJ = 175 °C, per Figure 5 in the datasheet. Designers must calculate junction temperature rise using RθJA and ensure layout provides adequate copper area or heatsinking to maintain TJ ≤175 °C under continuous leakage conditions.
