Product details
Overview
SA36-E3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 1.0 mA, 58.1 V maximum clamping voltage (VC) at 8.6 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive body control modules, industrial PLC I/O protection, and telecom power supply front-ends.
For engineers reviewing the SA36-E3/54 datasheet, SA36-E3/54 pinout, SA36-E3/54 application, or SA36-E3/54 equivalent, this device is evaluated for fast transient suppression in 12 V/24 V systems requiring AEC-Q101 qualification, DO-204AC (DO-15) through-hole mounting, and robust surge immunity per ISO 7637-2 and IEC 61000-4-5 standards.
Technical Context
The SA36-E3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering bi-polar clamping action only in reverse-biased mode (uni-directional polarity). Its 175 °C maximum junction temperature and 70 A IFSM rating support high-energy surge handling in automotive-grade environments.
Clamping performance is defined by low incremental surge resistance and sub-nanosecond response time, enabling effective suppression of ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and lightning-induced transients (IEC 61000-4-5). The device exhibits +0.041 %/°C temperature coefficient of VBR, ensuring stable breakdown across operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before clamping begins; sets system DC rail compatibility for 24 V nominal systems. |
| VBR (min/max) | 40.0 V / 44.2 V at 1.0 mA - Confirmed avalanche onset range; ensures reliable triggering above normal operating voltage with margin. |
| VC @ IPPM | 58.1 V at 8.6 A - Clamped voltage during 10/1000 µs surge; limits downstream IC stress to safe levels in protected circuits. |
| PPPM | 500 W - Peak pulse power capability; supports single-event surges up to 500 W without degradation under standard test conditions. |
| IFSM | 70 A - Non-repetitive forward surge current rating; enables survival of inrush or fault currents in power line applications. |
| TJ max. | 175 °C - Maximum junction temperature; allows operation in under-hood automotive or high-ambient industrial enclosures. |
| Package | DO-204AC (DO-15) - Standard axial-leaded package with matte tin-plated leads; compatible with wave soldering (275 °C, 10 s). |
Pinout & Package
SA36-E3/54 is a two-terminal uni-directional TVS diode in DO-204AC (DO-15) molded epoxy package. Polarity is marked by cathode band on one end; anode is unmarked. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry terminal in forward bias; connected to lower-potential side of protected circuit | Enables standard DC power rail placement: anode to ground or return path, cathode to line being protected. |
| Cathode (banded end) | Avalanche clamping node in reverse bias; connected to higher-potential line or signal | Provides low-impedance shunt path during overvoltage events; clamps transients to ≤58.1 V while diverting surge current. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/5A (Vishay) | Surface-mount SMA package (DO-214AC); same VWM/VC specs but lower IPPM (8.3 A vs. 8.6 A) and 400 W PPPM. | Designed for space-constrained PCBs where reflow assembly is preferred over through-hole wave soldering. | Select SMAJ36A-E3/5A when board real estate is limited and automated SMT placement is required. |
| 1.5KE36A (ON Semiconductor) | Higher PPPM (1500 W), larger DO-201AD package, 60 V VC at 25 A, not AEC-Q101 qualified. | Targeted at non-automotive industrial power supplies needing higher single-pulse energy absorption. | Choose 1.5KE36A only if >500 W surge margin is mandatory and AEC-Q101 compliance is not required. |
Compared with SMAJ36A-E3/5A and 1.5KE36A, SA36-E3/54 offers AEC-Q101 qualification and DO-15 through-hole robustness ideal for high-vibration automotive harness connections, while maintaining precise 36 V stand-off alignment with 24 V system architectures.

FAQ
What is the maximum clamping voltage of SA36-E3/54 under standard 10/1000 µs surge conditions?
The SA36-E3/54 has a maximum clamping voltage (VC) of 58.1 V at 8.6 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per JEDEC standards and ensures predictable overvoltage limiting for downstream 3.3 V or 5 V ICs. The SA36-E3/54 maintains this clamping performance across its full operating temperature range.
Is SA36-E3/54 qualified for automotive applications?
Yes, SA36-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications including body electronics, lighting, and powertrain subsystems. The qualification covers temperature cycling, humidity testing, and mechanical shock - all verified per the Vishay document 88378 revision 18-Sep-12. SA36-E3/54 meets the reliability requirements for under-hood and cabin-mounted modules.
What package type does SA36-E3/54 use, and what are its mounting considerations?
SA36-E3/54 uses the DO-204AC (DO-15) axial-leaded package with matte tin-plated leads. It supports wave soldering at 275 °C for up to 10 seconds per JESD 22-B106. Lead spacing is standardized for 0.300" (7.6 mm) minimum PCB hole-to-hole distance. The cathode band must be oriented toward the higher-potential side of the protected line.
How does the breakdown voltage tolerance of SA36-E3/54 affect circuit design?
The SA36-E3/54 specifies a VBR range of 40.0 V to 44.2 V at 1.0 mA test current. This ±5.5 % tolerance requires designers to ensure system operating voltage remains ≥10 % below minimum VBR (i.e., <36 V) to avoid premature conduction. The SA36-E3/54 is therefore optimized for stable 24 V nominal rails with typical ripple and tolerance margins.
Can SA36-E3/54 be used in bi-directional protection configurations?
No, SA36-E3/54 is a uni-directional TVS diode and must not be used for bi-directional transient suppression. Bi-directional variants carry the "CA" suffix (e.g., SA36CA). Using SA36-E3/54 in AC or dual-polarity signal paths risks forward conduction and failure. For bi-directional applications, select SA36CA-E3/54 or equivalent, which provides symmetric clamping in both polarities.
