Product details
Overview
SA13CHE3/54 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 sensitive electronics. 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, and clamps to ≤21.5 V at rated surge, meeting AEC-Q101 qualification for automotive use.
For engineers reviewing the SA13CHE3/54 datasheet, SA13CHE3/54 pinout, SA13CHE3/54 application, or SA13CHE3/54 equivalent, key selection criteria include its 500 W peak pulse power rating, low 1.0 µA reverse leakage at VWM, 175 °C max junction temperature, RoHS-compliant matte tin-plated leads, and suitability for protecting MOSFETs, ICs, and sensor signal lines against inductive switching transients.
Technical Context
This TVS diode operates as a clamping device in series with power or signal paths, conducting only when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, enabling fast response (<1 ns) and repeatable clamping performance across temperature.
The SA13CHE3/54 is specified for uni-directional operation with cathode marked by color band, supports 70 A non-repetitive forward surge (IFSM), and maintains 3.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C - critical for sustained thermal management in compact automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before conduction begins; defines safe working margin below system rail. |
| VBR (min/max) | 14.4 V / 15.9 V at IT = 1.0 mA - tight 5 % tolerance ensures predictable turn-on across production lots and temperature. |
| IPPM | 23.3 A - peak surge current it safely clamps under standardized 10/1000 µs waveform, directly sizing protection robustness. |
| VC | ≤21.5 V - maximum clamped voltage at IPPM; determines worst-case stress imposed on downstream protected ICs. |
| PPPM | 500 W - peak pulse power handling capability; validates suitability for high-energy transients like load dump or ISO 7637-2 pulses. |
| TJ max | 175 °C - maximum junction temperature; enables reliable operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during clamping | Connected to protected circuit's ground or low-side return path; polarity-critical for uni-directional operation. |
| Cathode | Reverse-biased terminal during normal operation | Marked with color band; connected to protected line (e.g., 12 V rail or signal trace) to enable clamping to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR and low leakage over lifetime, even under thermal cycling and humidity exposure. |
| 500 W peak pulse power (10/1000 µs) | Provides robust protection against common automotive transients such as ISO 16750-2 load dump and ISO 7637-2 pulse 1/2a/5a. |
| AEC-Q101 qualification | Validates reliability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients, improving protection margin for 3.3 V or 5 V logic. |
| RoHS-compliant HE3 suffix | Indicates AEC-Q101 qualified, JESD 201 Class 2 whisker-resistant matte tin plating for long-term solder joint integrity. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |

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 specs but SMC (DO-214AB) package; 600 W PPPM; higher IPPM (32.5 A). | Requires larger PCB footprint; better suited for higher-power industrial designs where space permits. | Select SMAJ13A-E3/52 if board layout allows SMC package and higher surge margin is needed. |
| 1.5KE13A (ON Semiconductor) | Same DO-204AC package and VWM = 13 V, but 1.5 kW PPPM; higher VC = 21.2 V; not AEC-Q101 qualified. | Higher energy handling but lacks automotive qualification; suitable for commercial/industrial only. | Choose 1.5KE13A for cost-sensitive non-automotive applications requiring higher single-pulse energy absorption. |
Compared with SMAJ13A-E3/52 and 1.5KE13A, SA13CHE3/54 offers AEC-Q101 qualification in the compact DO-15 package with optimized clamping voltage for automotive 12 V systems - making it the preferred choice where qualification, size, and precise VC are jointly critical.

FAQ
What is the clamping voltage of SA13CHE3/54 at its rated peak pulse current?
The SA13CHE3/54 has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPPM) of 23.3 A under the 10/1000 µs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuits during surge events. The SA13CHE3/54 maintains this clamping performance across its full operating temperature range, supporting design margin calculations for downstream ICs.
Is SA13CHE3/54 suitable for automotive applications?
Yes, SA13CHE3/54 is AEC-Q101 qualified and specifically designed for automotive use, including engine control modules, body electronics, and ADAS sensor interfaces. Its 175 °C maximum junction temperature, glass-passivated junction, and JESD 201 Class 2 whisker-resistant plating meet stringent automotive reliability requirements. The SA13CHE3/54 is explicitly listed in Vishay's AEC-Q101 qualified product list with full test report traceability.
What does the "HE3" suffix indicate in SA13CHE3/54?
The "HE3" suffix in SA13CHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade "E3" versions and confirms compliance with automotive reliability standards, including temperature cycling, highly accelerated life testing (HALT), and electrostatic discharge (ESD) robustness. The SA13CHE3/54 meets all mechanical and environmental requirements defined in the Vishay SAxxA family datasheet revision 18-Sep-12.
How does SA13CHE3/54 differ from bi-directional SA13CA variants?
The SA13CHE3/54 is a uni-directional TVS diode with cathode marking and forward voltage drop (~3.5 V at 100 A), intended for DC rail protection where polarity is fixed. In contrast, SA13CA is bi-directional, unmarked, and symmetrical - used in AC or floating signal lines. Their breakdown voltages differ slightly: SA13CHE3/54 specifies VBR = 14.4–15.9 V, while SA13CA has identical VBR but applies in both directions. The SA13CHE3/54 cannot substitute for SA13CA in AC-coupled applications.
What is the maximum reverse leakage current for SA13CHE3/54 at rated VWM?
The SA13CHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated stand-off voltage (VWM) of 13 V and TA = 25 °C. This ultra-low leakage ensures negligible standby power draw and avoids interference with high-impedance sensor inputs or precision reference circuits. Leakage remains below 5 µA up to 125 °C, maintaining performance in under-hood automotive environments.
