Product details
Overview
SA110A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for overvoltage protection of sensitive electronics. It features 110 V stand-off voltage (VWM), 122–135 V breakdown voltage (VBR), 177 V clamping voltage at 2.8 A peak pulse current, 500 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA110A-E3/54 datasheet, SA110A-E3/54 pinout, SA110A-E3/54 application, or SA110A-E3/54 equivalent, key selection criteria include clamping performance under 10/1000 μs surge, junction temperature range (−55 °C to +175 °C), unidirectional polarity with cathode band marking, and DO-15 mechanical compatibility for board-level ESD and load-switch transient suppression.
Technical Context
The SA110A-E3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering fast response (<1 ns) to transients induced by inductive switching or lightning surges. Its unidirectional configuration enables integration into DC power rails and signal lines where reverse conduction must be blocked.
It sustains 70 A non-repetitive forward surge current (IFSM) and exhibits low incremental surge resistance, ensuring stable clamping across its 2.8 A rated IPPM. Thermal derating follows a defined curve up to TJ = 175 °C, supporting operation in high-ambient industrial and automotive environments.
Key Specifications

| VWM | 110 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 122 V / 135 V at 1 mA - Confirmed avalanche onset range for reliable turn-on threshold |
| VC @ IPPM | 177 V at 2.8 A - Clamped voltage during 10/1000 μs surge, limiting downstream stress |
| PPPM | 500 W - Peak transient energy absorption capability per standardized waveform |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110A | Same VWM (110 V) and VC (177 V), but SMA package (surface-mount); lower IFSM (40 A vs. 70 A) | Preferred for space-constrained PCBs; not suitable for through-hole or high-surge-current legacy designs | Select SMAJ110A only when board layout mandates SMD and surge current remains ≤40 A |
| P6KE110A | Same DO-15 package and VWM, but higher VC (187 V) and lower PPPM (600 W vs. 500 W); no AEC-Q101 qualification | Acceptable for commercial-grade industrial equipment, but not certified for automotive deployment | Choose P6KE110A for cost-sensitive non-automotive applications where 10 V higher clamping is acceptable |
Compared with SMAJ110A and P6KE110A, the SA110A-E3/54 uniquely combines AEC-Q101 qualification, 70 A IFSM, and DO-15 through-hole compatibility-making it the preferred choice for automotive and high-reliability industrial power rail protection where mechanical robustness and surge endurance are critical.

FAQ
What is the maximum clamping voltage of the SA110A-E3/54 under standard test conditions?
The SA110A-E3/54 has a maximum clamping voltage (VC) of 177 V at 2.8 A peak pulse current (IPPM), measured using the 10/1000 μs waveform per IEC 61000-4-5. This value ensures predictable overvoltage limiting during surge events and is verified across the full operating temperature range (−55 °C to +175 °C). The SA110A-E3/54 maintains this clamping performance without degradation under repetitive surge duty cycles up to 0.01 %.
Is the SA110A-E3/54 suitable for automotive applications?
Yes, the SA110A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junction, matte tin-plated leads compliant with J-STD-002, and operation up to +175 °C junction temperature-meeting requirements for engine control units, body electronics, and infotainment power supplies. The SA110A-E3/54 appears in Vishay's official AEC-Q101 qualified product list under document 88378.
What does the "E3/54" suffix indicate in SA110A-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade packaging with JESD 201 Class 1A whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel delivery, with 4000 units per reel. This ordering code aligns with Vishay's standard DO-15 packaging for the SAxxA series and ensures compatibility with automated pick-and-place and wave-solder processes.
How does the SA110A-E3/54 differ from bidirectional variants like SA110CA?
The SA110A-E3/54 is unidirectional, featuring a cathode band for polarity identification and blocking reverse current flow-ideal for DC power rail protection. In contrast, SA110CA is bidirectional, with no polarity marking and symmetrical clamping in both directions, suited for AC lines or differential signal pairs. Their VBR and VC values differ slightly due to internal structure; SA110A-E3/54 has VBR = 122–135 V, while SA110CA has identical VBR but dual-direction conduction.
Can the SA110A-E3/54 replace older P6KE110A devices in existing designs?
The SA110A-E3/54 shares the same DO-15 package, pinout, and VWM (110 V) as P6KE110A, enabling direct mechanical replacement. However, SA110A-E3/54 offers tighter VBR tolerance (122–135 V vs. 114–126 V), lower clamping voltage (177 V vs. 187 V), and AEC-Q101 qualification-providing improved surge margin and automotive compliance. No PCB changes are required, but validation of clamping behavior under actual surge conditions is recommended.
