Product details
Overview
SA110CA-E3/54 from Vishay General Semiconductor is a bidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-15 package, rated for 110 V stand-off voltage (VWM), 135 V maximum breakdown voltage (VBR), and 500 W peak pulse power (10/1000 μs). It clamps transients to ≤177 V at 2.8 A peak pulse current and operates from –55 °C to +175 °C, targeting protection of MOSFETs and sensor signal lines in industrial power supplies.
For engineers reviewing the SA110CA-E3/54 datasheet, SA110CA-E3/54 pinout, SA110CA-E3/54 application, or SA110CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, low leakage (<1.0 μA at 110 V), and thermal stability up to 175 °C junction temperature.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) to ESD and lightning-induced surges. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating circuits without polarity concerns, and its 175 °C max junction temperature supports under-hood automotive and high-ambient industrial use.
The device delivers 500 W peak pulse power per 10/1000 μs waveform with 0.01 % duty cycle, and exhibits low incremental surge resistance-critical for limiting let-through energy during repetitive transients in motor drive gate drivers and telecom line interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 110 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 122 V / 135 V at 1 mA - Ensures reliable breakdown onset within tight tolerance for predictable protection threshold |
| VC @ IPPM | 177 V at 2.8 A - Clamped voltage level defining worst-case overvoltage seen by protected circuitry |
| ID @ VWM | <1.0 μA - Negligible leakage current preserves signal integrity in high-impedance sensor interfaces |
| PPPM | 500 W (10/1000 μs) - Sustains high-energy surges common in inductive load switching and lighting events |

| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling and humidity testing |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; bidirectional symmetry means no cathode marking-both terminals are electrically identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals conduct identically during positive or negative voltage excursions beyond VBR |
| Case | Mechanical mounting surface | Non-electrical; provides thermal path to PCB copper and meets UL 94 V-0 flammability rating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110CA | Same VWM (110 V), lower PPPM (400 W), SMA package (surface-mount) | Requires PCB rework for SMT assembly; unsuitable for through-hole legacy designs | Select when board space is constrained and reflow compatibility is required |
| P6SMB110CA | Same VWM (110 V), identical DO-214AA package, 600 W PPPM rating | Higher peak power margin but larger footprint than DO-15; slightly higher clamping voltage (187 V) | Select when higher surge margin is prioritized over mechanical fit in compact layouts |
Compared with SMAJ110CA and P6SMB110CA, SA110CA-E3/54 offers optimal balance of DO-15 through-hole compatibility, AEC-Q101 qualification, and 500 W surge handling-making it ideal for cost-sensitive industrial upgrades and automotive retrofit modules where leaded assembly remains standard.

FAQ
What is the maximum clamping voltage of SA110CA-E3/54 at its rated peak pulse current?
The SA110CA-E3/54 has a maximum clamping voltage (VC) of 177 V at its rated peak pulse current (IPPM) of 2.8 A using a 10/1000 μs waveform. This value is measured per Figure 9 in the Vishay datasheet 88378 and defines the upper limit of overvoltage imposed on protected circuitry during surge events. The SA110CA-E3/54 maintains this clamping performance across its full operating temperature range.
Is SA110CA-E3/54 suitable for automotive applications?
Yes, SA110CA-E3/54 is AEC-Q101 qualified per the Vishay datasheet revision 27-Sep-2021, confirming its reliability for automotive use cases including body electronics, infotainment interfaces, and sensor protection. Its 175 °C maximum junction temperature and DO-15 mechanical robustness support under-hood and chassis-mounted deployments. SA110CA-E3/54 meets requirements for ESD immunity and surge withstand in ISO 10605 and ISO 7637-2 environments.
Does SA110CA-E3/54 have polarity markings on the package?
No, SA110CA-E3/54 does not have polarity markings because it is a bidirectional TVS diode. As stated in the Vishay datasheet, "no marking on bidirectional types." Both terminals exhibit identical electrical behavior-clamping symmetrically for positive and negative transients-so orientation during PCB insertion is irrelevant. This simplifies assembly and eliminates risk of reverse installation.
What is the reverse leakage current specification for SA110CA-E3/54 at rated stand-off voltage?
At its rated stand-off voltage (VWM) of 110 V and TA = 25 °C, SA110CA-E3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA. This low leakage ensures minimal loading on high-impedance signal paths such as sensor outputs or LIN bus lines. The SA110CA-E3/54 maintains leakage below 5 μA even at elevated temperatures up to 125 °C, per derating curves in the datasheet.
Can SA110CA-E3/54 replace unidirectional TVS diodes like SA110A-E3/54 in existing designs?
No, SA110CA-E3/54 cannot directly replace unidirectional SA110A-E3/54 without circuit review. While both share VWM = 110 V and DO-15 packaging, SA110CA-E3/54 is bidirectional with symmetrical clamping, whereas SA110A-E3/54 is unidirectional and requires correct cathode orientation. Substitution may cause unintended conduction in DC-biased rails. SA110CA-E3/54 is intended for AC-coupled or floating applications-not DC power line protection.
