Product details
Overview
SA36A-E3/54 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 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 1 mA, 58.1 V clamping voltage (VC) at 8.6 A peak pulse current, and 500 W peak pulse power rating with 10/1000 μs waveform - deployed in power supply input stages and I/O line protection for industrial control systems.
For engineers reviewing the SA36A-E3/54 datasheet, SA36A-E3/54 pinout, SA36A-E3/54 application, or SA36A-E3/54 equivalent, key selection criteria include clamping performance under 8.6 A surge, thermal derating above 25 °C, unidirectional polarity marking, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The SA36A-E3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering fast response (<1 ns) to transient overvoltages. Its unidirectional configuration uses a cathode band for polarity identification and exhibits low incremental surge resistance, enabling effective voltage clamping during inductive switching events.
It complies with JEDEC JESD22-B106 soldering standards (275 °C, 10 s), meets UL 94 V-0 flammability requirements, and is rated for -55 °C to +175 °C operating junction temperature - supporting robust operation in high-temperature industrial and automotive environments.
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 |
|---|---|---|---|
| SMAJ36A | Same VWM (36 V), lower PPPM (400 W), SMA package (surface-mount) | Requires PCB rework for SMT layout; lacks AEC-Q101 qualification | Select when board space is constrained and automotive qualification is not required |
| P6SMB36A | Identical VWM and VBR range, same DO-15 package, 600 W PPPM rating | Higher peak power handling but higher VC (60.5 V) reduces protection margin | Prefer where higher surge immunity is prioritized over tight clamping voltage |
Compared with SMAJ36A and P6SMB36A, the SA36A-E3/54 offers AEC-Q101 qualification and optimal clamping ratio (58.1 V) for 36 V systems - making it preferred for automotive and industrial designs requiring certified reliability and precise voltage limiting.

FAQ
What is the maximum clamping voltage of the SA36A-E3/54 under standard test conditions?
The SA36A-E3/54 has a maximum clamping voltage (VC) of 58.1 V at 8.6 A peak pulse current with a 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during surge events. The SA36A-E3/54 maintains this clamping performance across its specified operating temperature range.
Is the SA36A-E3/54 suitable for automotive applications?
Yes, the SA36A-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications such as body control modules, infotainment power rails, and sensor interfaces. Its -55 °C to +175 °C operating temperature range, glass-passivated junction, and DO-15 mechanical robustness meet automotive environmental and reliability requirements. The SA36A-E3/54 is explicitly listed in Vishay's AEC-Q101 qualified product documentation.
How does the SA36A-E3/54 differ from bidirectional TVS diodes like SA36CA?
The SA36A-E3/54 is unidirectional and features a cathode band for polarity identification, while SA36CA is bidirectional with no polarity marking. The SA36A-E3/54 conducts only in reverse breakdown, making it ideal for DC rail protection with defined ground reference. In contrast, SA36CA protects AC-coupled or floating lines. Their VBR and VC values differ slightly due to internal structure - SA36A-E3/54 has VBR 40.0–44.2 V, whereas SA36CA is symmetrically rated.
What is the leakage current specification for the SA36A-E3/54 at its rated standoff voltage?
The SA36A-E3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its 36 V stand-off voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage ensures minimal power loss and signal distortion in high-impedance sensing or precision analog circuits. Leakage remains within specification up to +175 °C junction temperature, as confirmed by Vishay's derating curves.
Can the SA36A-E3/54 be used in surface-mount designs?
No, the SA36A-E3/54 uses a through-hole DO-15 (DO-204AC) package with axial leads and is not compatible with surface-mount assembly. For SMT alternatives, consider the SMAJ36A (SMA package) or SMCJ36A (SMC package), which share similar electrical ratings but require PCB redesign. The SA36A-E3/54's leaded construction supports manual repair, high-voltage creepage, and mechanical strain relief in ruggedized industrial layouts.
