Product details
Overview
SA100A-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 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR) at 1 mA, 162 V clamping voltage (VC) at 3.1 A peak pulse current, and 500 W peak pulse power rating with 10/1000 μs waveform - deployed in power supply input stages and DC bus lines of industrial motor drives.
For engineers reviewing the SA100A-E3/54 datasheet, SA100A-E3/54 pinout, SA100A-E3/54 application, or SA100A-E3/54 equivalent, key selection criteria include clamping performance under 3.1 A IPPM, thermal derating above 25 °C, unidirectional polarity marking, DO-15 mechanical compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (111–123 V), it avalanches to divert transient energy away from downstream ICs or MOSFETs. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 μA at 100 V), while the DO-15 package supports lead-free soldering per J-STD-002 and JESD 22-B102.
It delivers 500 W peak pulse power (10/1000 μs) with 0.01 % duty cycle, and its clamping voltage remains ≤162 V up to 3.1 A IPPM - enabling robust protection of 100 V-rated systems such as telecom power interfaces and industrial PLC I/O modules without overstressing protected components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 111 V / 123 V at 1 mA - defines precise avalanche onset window for predictable protection threshold |
| VC @ IPPM | 162 V at 3.1 A - clamping voltage during full 500 W transient, limiting stress on protected 100 V rail |
| PPPM | 500 W - peak surge energy handling capability with standard 10/1000 μs waveform |
| ID @ VWM | ≤1.0 μA - ultra-low reverse leakage preserves system efficiency and signal integrity |
| TJ max. | +175 °C - enables operation in high-temperature environments like engine control units |
| Polarity | Unidirectional - cathode marked by band; blocks forward conduction, clamps reverse surges |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads. Complies with UL 94 V-0 flammability rating and JESD 201 class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-impedance path during clamping | Connected to protected circuit ground or low-side return; enables shunt diversion of surge current |
| Cathode | Reverse-biased terminal / clamping node | Marked with color band; connects to line/rail being protected; avalanches when V > VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable, repeatable breakdown voltage over temperature and lifetime with minimal parameter drift |
| 500 W peak pulse power (10/1000 μs) | Handles common lightning-induced surges and inductive switching spikes in 100 V systems |
| AEC-Q101 qualified | Validated for automotive applications including body electronics and powertrain subsystems |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving protection margin for sensitive MOSFETs |
| Solder dip rated 275 °C / 10 s | Supports standard reflow and wave solder processes without degradation of junction integrity |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Same VWM (100 V) and VC (162 V), but SMB package (surface-mount); 600 W PPPM rating | Requires PCB redesign for SMD layout; better thermal dissipation in compact layouts | Select when board space is constrained and reflow assembly is used |
| 1.5KE100A | Same VWM (100 V), higher VC (165 V), through-hole DO-201 package; 1500 W PPPM | Larger footprint and higher surge capacity; suited for primary-level AC/DC front-end protection | Select when higher single-pulse energy handling (>500 W) is required |
Compared with SMBJ100A and 1.5KE100A, SA100A-E3/54 offers identical clamping performance in a cost-optimized DO-15 axial package with AEC-Q101 qualification - making it ideal for automotive and industrial through-hole designs where legacy assembly and qualification compliance are critical.

FAQ
What is the breakdown voltage range of SA100A-E3/54?
The SA100A-E3/54 has a guaranteed breakdown voltage (VBR) range of 111 V to 123 V at 1 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable design margining for 100 V systems.
Is SA100A-E3/54 suitable for automotive applications?
Yes, SA100A-E3/54 is AEC-Q101 qualified and rated for operation from -55 °C to +175 °C junction temperature. Its glass-passivated junction and DO-15 construction meet automotive reliability requirements for body electronics, lighting modules, and power distribution units where unidirectional surge protection is needed.
What is the maximum clamping voltage for SA100A-E3/54 under surge conditions?
The SA100A-E3/54 exhibits a maximum clamping voltage (VC) of 162 V at 3.1 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is confirmed in the Vishay datasheet and defines the upper voltage limit imposed on protected circuits during transient events.
Does SA100A-E3/54 have polarity marking, and how is it identified?
Yes, SA100A-E3/54 is unidirectional and features a cathode band marking on the DO-15 package body. The banded end is the cathode terminal and must be connected toward the line/rail being protected; the opposite lead is the anode, typically tied to ground or low-side reference.
What is the peak pulse power rating and test condition for SA100A-E3/54?
The SA100A-E3/54 is rated for 500 W peak pulse power (PPPM) with a 10/1000 μs double-exponential waveform at 0.01 % duty cycle. This rating is validated per Figure 1 in the Vishay datasheet 88378 and applies at TA = 25 °C, with derating required above that ambient temperature.
