Product details
Overview
SA13HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on power 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), 21.5 V maximum clamping voltage (VC) at IPPM, and AEC-Q101 qualification for automotive reliability.
For engineers reviewing the SA13HE3/54 datasheet, SA13HE3/54 pinout, SA13HE3/54 application, or SA13HE3/54 equivalent, key selection criteria include its 500 W peak pulse power rating (10/1000 μs), low 1.0 μA reverse leakage at VWM, 3.0 W steady-state power dissipation, 175 °C max junction temperature, and RoHS-compliant, whisker-tested (JESD 201 Class 2) matte tin-plated leads.
Technical Context
The SA13HE3/54 operates as a uni-directional avalanche diode with glass-passivated junction, enabling fast response to ESD and surge events. Its clamping behavior is defined by a well-controlled VBR range (14.4–15.9 V) and low incremental surge resistance, delivering consistent VC = 21.5 V at 23.3 A under standardized 10/1000 μs waveform conditions.
It supports high-reliability automotive applications via AEC-Q101 qualification and meets JESD 22-B106 solderability (275 °C, 10 s). The device exhibits a +0.013 %/°C temperature coefficient of VBR, ensuring stable breakdown across operating temperature (−55 °C to +175 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before significant conduction begins |
| VBR (min/max) | 14.4 V / 15.9 V at 1.0 mA - Ensures reliable turn-on within tight tolerance for predictable clamping onset |
| IPPM | 23.3 A (10/1000 μs) - Sustains 500 W transient energy without failure under standard surge test |
| VC | 21.5 V at IPPM - Limits downstream voltage stress to safe levels during worst-case surge |
| PPPM | 500 W - Peak pulse power handling capability defines protection margin against lightning/inductive spikes |
| TJ max | +175 °C - Enables operation in under-hood automotive environments and high-ambient industrial settings |
| Leakage (ID) | 1.0 μA at VWM - Minimizes standby power loss and avoids false triggering in low-power circuits |
Pinout & Package
SA13HE3/54 is housed in a DO-204AC (DO-15) molded epoxy package with axial leads. The cathode is marked by a color band on the body; polarity must be observed during PCB layout to ensure correct uni-directional clamping orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to protected line's lower-potential side (e.g., GND or low-side rail) to complete clamping loop |
| Cathode | Avalanche conduction node / Clamping output | Connected to the line being protected (e.g., 12 V supply or signal trace); conducts when VAK exceeds VBR |

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 (Vishay) | Same VWM/VBR specs but in SMA (DO-214AC) surface-mount package; 500 W rating retained | Requires SMT reflow process and board space optimization; not drop-in compatible with through-hole SA13HE3/54 | Select for space-constrained designs where automated assembly and higher board density are prioritized |
| 1N6132A (ON Semiconductor) | Identical DO-204AC package and 13 V VWM, but lower IPPM (21.5 A) and higher VC (22.5 V); not AEC-Q101 qualified | Lacks automotive qualification and has marginally reduced surge margin; suitable for commercial-grade systems only | Select for cost-sensitive non-automotive applications where full AEC-Q101 compliance is not required |
Compared with SMAJ13A-E3/52 and 1N6132A, SA13HE3/54 uniquely combines through-hole manufacturability, AEC-Q101 qualification, and verified 23.3 A/21.5 V clamping performance-making it optimal for automotive and industrial through-hole designs requiring zero-layout change and certified reliability.

FAQ
What is the clamping voltage of SA13HE3/54 and how is it measured?
The SA13HE3/54 has a maximum clamping voltage (VC) of 21.5 V, measured at its rated peak pulse current (IPPM) of 23.3 A using the standardized 10/1000 μs double-exponential waveform. This value reflects the actual voltage seen across the device terminals during worst-case surge conditions and is guaranteed per Vishay's datasheet (Document Number: 88378, Rev. 18-Sep-12). The SA13HE3/54 maintains this clamping performance across its full operating temperature range.
Is SA13HE3/54 suitable for automotive applications?
Yes, SA13HE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood and body-control modules. Its 175 °C maximum junction temperature, JESD 201 Class 2 whisker resistance, and validated performance under ISO 7637-2 load-dump and pulse tests confirm suitability. The SA13HE3/54 meets stringent automotive reliability requirements without derating in typical vehicle environments.
What does the "HE3" suffix indicate in SA13HE3/54?
The "HE3" suffix in SA13HE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker testing. It distinguishes the part from commercial-grade "E3" variants (e.g., SA13A-E3/54), which lack automotive qualification. The "54" refers to the preferred packaging code-13-inch paper tape and reel, 4000 units per reel-as specified in Vishay's ordering information.
How does SA13HE3/54 differ from bi-directional TVS diodes like SA13CA?
SA13HE3/54 is a uni-directional TVS diode with polarity-sensitive operation (cathode-banded), optimized for DC power line protection where only positive-going transients occur. In contrast, SA13CA is bi-directional and symmetrical, used for AC lines or data signals with bipolar threats. SA13HE3/54 offers lower forward voltage and tighter VBR tolerance than its bi-directional counterpart, making it preferable for 12 V rail clamping.
What is the thermal derating behavior of SA13HE3/54 above 25 °C ambient?
SA13HE3/54 follows Vishay's standard pulse derating curve (Fig. 2 in datasheet 88378): peak pulse power remains at 100% up to 25 °C, then linearly decreases to ~50% at 125 °C and ~25% at 175 °C. Steady-state power (PD = 3.0 W) derates from 75 °C lead temperature (Fig. 5), reaching zero at ~200 °C. Designers must apply these curves when sizing heatsinking or estimating surge repetition limits in hot environments for SA13HE3/54.
