Product details
Overview
SA130A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 130 V stand-off voltage (VWM), 144–159 V breakdown voltage (VBR) at 1.0 mA test current, 209 V maximum clamping voltage at 2.4 A peak pulse current, 500 W peak pulse power rating (10/1000 μs waveform), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA130A-E3/54 datasheet, SA130A-E3/54 pinout, SA130A-E3/54 application, or SA130A-E3/54 equivalent, key selection criteria include its unidirectional polarity, DO-15 mechanical compatibility, 175 °C maximum junction temperature, low incremental surge resistance, and compliance with JESD 22-B106 soldering standards - all critical for robust overvoltage protection in industrial and automotive power rails.
Technical Context
The SA130A-E3/54 operates as a silicon avalanche diode with glass-passivated chip junction, enabling fast response time (<1 ns) and stable clamping under repetitive transient events. Its unidirectional configuration provides forward conduction path during overvoltage while blocking reverse leakage up to 1.0 μA at 130 V.
Designed for 10/1000 μs surge waveforms at 0.01% duty cycle, it delivers 500 W peak pulse power dissipation and supports 70 A non-repetitive forward surge current (IFSM). Thermal derating follows a defined curve from 3.0 W at TL = 75 °C down to zero at TJ = 175 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ130A | Same DO-214AC package; 130 V VWM, 211 V VC @ 2.4 A; slightly higher clamping voltage | Higher thermal resistance due to surface-mount footprint; less suitable for through-hole board layouts | Select when space-constrained PCBs require SMD mounting and thermal management permits |
| ON Semiconductor 1.5KE130A | Higher 1500 W PPPM rating but larger DO-201AD package; 219 V VC @ 6.8 A | Designed for higher-energy surges; requires larger board area and different mounting process | Choose for legacy designs already using DO-201AD footprints or where >500 W surge margin is mandatory |
Compared with SMAJ130A and 1.5KE130A, the SA130A-E3/54 offers optimal balance of axial DO-15 compatibility, AEC-Q101 qualification, and precise 209 V clamping-making it preferred for new automotive and industrial through-hole designs requiring proven reliability and JEDEC-standardized lead finish.

FAQ
What is the maximum clamping voltage of the SA130A-E3/54 under standard test conditions?
The SA130A-E3/54 has a maximum clamping voltage (VC) of 209 V when subjected to a 10/1000 μs waveform at 2.4 A peak pulse current. This value is measured per IEC 61000-4-5 guidelines and defines the upper voltage limit imposed on protected circuits during surge events. The SA130A-E3/54 maintains this clamping performance across its full operating temperature range.
Is the SA130A-E3/54 suitable for automotive applications?
Yes, the SA130A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its 175 °C maximum junction temperature, glass-passivated junction, and robust surge handling (70 A IFSM, 500 W PPPM) meet requirements for engine control units, body electronics, and infotainment power supplies. The SA130A-E3/54 also complies with JESD 22-B106 soldering standards used in automotive manufacturing.
What does the "E3/54" suffix indicate in SA130A-E3/54?
The "E3" denotes RoHS-compliant, commercial-grade termination with JESD 201 Class 1A whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel packaging containing 4000 units. This ordering format ensures consistent lead finish, traceability, and automated assembly compatibility. The SA130A-E3/54 is not AEC-Q101 qualified unless ordered with HE3 suffix.
How does the SA130A-E3/54 differ from bidirectional TVS diodes like SA130CA?
The SA130A-E3/54 is unidirectional and features a cathode band marking, allowing it to conduct only in forward bias during clamping - ideal for DC power rail protection. In contrast, SA130CA is bidirectional with no polarity marking and clamps symmetrically for AC or differential signal lines. Their VBR and VC values differ slightly; SA130A-E3/54 has 144–159 V VBR, while SA130CA has identical VBR but double the ID limit below 10 V VWM.
What is the thermal derating behavior of the SA130A-E3/54 above 25 °C ambient?
The SA130A-E3/54 follows a linear derating curve from 3.0 W at TL = 75 °C down to zero power dissipation at TJ = 175 °C. Its steady-state power capability decreases proportionally with increasing lead temperature, as defined in Figure 5 of the Vishay datasheet 88378. Engineers must calculate board-level thermal resistance to ensure junction temperature remains within limits during continuous operation. The SA130A-E3/54 does not require heatsinking for typical transient-only use.
