Product details
Overview
SA100C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR) at 1 mA, 162 V maximum clamping voltage (VC) at 3.1 A peak pulse current, and 500 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, sensor interfaces, and industrial I/O lines against ESD and inductive switching surges.
For engineers reviewing the SA100C-E3/54 datasheet, SA100C-E3/54 pinout, SA100C-E3/54 application, or SA100C-E3/54 equivalent, this page delivers verified electrical parameters, bi-directional TVS behavior, DO-15 terminal configuration, AEC-Q101 qualification status, and direct alternatives for surge protection design in automotive and industrial control systems.
Technical Context
The SA100C-E3/54 operates as a bi-directional avalanche diode, symmetrically clamping transient voltages above ±111 V in either polarity without polarity marking. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing 8/20 µs and 10/1000 µs surge events per IEC 61000-4-5 and ISO 16750-2.
Rated for -55 °C to +175 °C junction temperature, it supports high-reliability applications with 3.0 W steady-state power dissipation at 75 °C lead temperature and meets JESD22-B102 solderability and JESD201 Class 1A whisker resistance requirements via matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working margin below breakdown. |
| VBR (min/max) | 111 V / 123 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on across production lot and temperature. |
| VC @ IPPM | 162 V at 3.1 A - Clamped voltage during 10/1000 µs transient; determines protected circuit's maximum overvoltage exposure. |
| PPPM | 500 W - Peak pulse power handling capability; validates robustness against repetitive lightning-induced surges (0.01% duty cycle). |
| IPPM | 3.1 A - Peak pulse current corresponding to VC; used to size series impedance and verify coordination with upstream fusing. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive or high-ambient industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Same VWM (100 V), higher PPPM (600 W), SMC package (DO-214AB), lower VC (165 V @ 3.2 A) | Requires PCB footprint change; better suited for space-constrained layouts needing higher surge margin. | Select SMBJ100CA when board area allows SMC and system-level surge test requires >500 W margin. |
| 1.5KE100CA | Same VWM (100 V), same DO-204AC package, higher PPPM (1500 W), higher VC (170 V @ 8.8 A) | Compatible footprint but larger thermal mass; used where single-event lightning strike immunity dominates. | Choose 1.5KE100CA only if tested surge levels exceed 500 W and layout permits higher clamping voltage tolerance. |
Compared with SA100C-E3/54, SMBJ100CA offers higher power density in smaller SMC packaging but requires layout revision, while 1.5KE100CA retains DO-204AC compatibility at significantly higher surge capacity - making SA100C-E3/54 optimal for cost-sensitive, AEC-Q101–required designs balancing performance and footprint.

FAQ
What is the polarity configuration of SA100C-E3/54?
The SA100C-E3/54 is a bi-directional TVS diode with no polarity marking on the DO-204AC package. Its symmetrical avalanche structure allows it to clamp transients of either polarity equally - eliminating orientation concerns during assembly and enabling use on AC-coupled or differential lines like RS-485 without external circuitry. This behavior is confirmed in the Vishay datasheet section "For bi-directional types, use CA suffix" and electrical characteristics table.
Is SA100C-E3/54 qualified for automotive applications?
Yes, SA100C-E3/54 is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet footnote (1) and Mechanical Data section. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD - validating its suitability for automotive powertrain, body electronics, and infotainment systems where field reliability is critical. The HE3 variant is also available for enhanced whisker resistance.
What is the maximum clamping voltage of SA100C-E3/54 under surge conditions?
The maximum clamping voltage (VC) of SA100C-E3/54 is 162 V at a peak pulse current (IPPM) of 3.1 A with a 10/1000 µs waveform, per the Electrical Characteristics table on page 2 of the Vishay document 88378. This value defines the upper voltage limit imposed on protected circuitry during standardized surge events and is measured under controlled lab conditions per ANSI/IEEE C62.35.
Does SA100C-E3/54 meet RoHS requirements?
Yes, SA100C-E3/54 carries the E3 suffix, which Vishay specifies as RoHS-compliant per Directive 2011/65/EU. The device uses matte tin-plated leads and halogen-free molding compound compliant with JEDEC JS709A, and its material categorization is documented in Vishay's policy document 99912. Compliance is verified through third-party testing and declared in the ordering information section.
How does SA100C-E3/54 differ from the uni-directional SA100A-E3/54?
SA100C-E3/54 is bi-directional with symmetrical clamping in both polarities and no cathode band marking, whereas SA100A-E3/54 is uni-directional with a cathode band and only clamps in reverse bias. Their VWM (100 V) and PPPM (500 W) match, but SA100A-E3/54 has a forward voltage drop (VF = 3.5 V at 100 A) and higher IFSM (70 A), making it suitable for DC power rail protection where polarity is fixed - unlike SA100C-E3/54's use in AC or bidirectional signal paths.
