Product details
Overview
SA100-E3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 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, 500 W peak pulse power rating (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA100-E3/54 datasheet, SA100-E3/54 pinout, SA100-E3/54 application, or SA100-E3/54 equivalent, this device is selected for robust ESD and surge protection in 12 V–48 V industrial power supplies, automotive body control modules, and sensor interface circuits where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.45), and stable junction temperature up to +175 °C are required.
Technical Context
The SA100-E3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling precise breakdown behavior and repeatable clamping under transient stress. Its uni-directional polarity-marked with cathode band-supports DC-biased protection paths without reverse conduction during normal operation.
It delivers 500 W peak pulse power per 10/1000 μs waveform at TA = 25 °C, derates linearly above 25 °C per Fig. 2, and sustains 70 A non-repetitive forward surge current (IFSM) per 10 ms half-sine wave. Thermal design must account for 3.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous reverse operating voltage before clamping begins; sets protection threshold for 100 V nominal systems. |
| VBR (min/max) | 111 V / 123 V at IT = 1 mA - Confirmed avalanche onset range; ensures reliable triggering above system overvoltage margin. |
| VC @ IPPM | 162 V at 3.1 A - Clamped voltage during full-rated 500 W transient; limits downstream voltage stress to safe levels. |
| PPPM | 500 W - Peak pulse power handling capability per standard 10/1000 μs waveform; defines surge energy absorption capacity. |
| IFSM | 70 A - Non-repetitive forward surge current rating; supports high-energy inductive switch-off events in automotive solenoid drivers. |
| TJ max. | +175 °C - Maximum junction temperature; enables operation in under-hood automotive environments and high-ambient industrial enclosures. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with matte tin-plated leads, UL 94 V-0 molding compound, and JESD 22-B102 solderability compliance. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking on one end. Leads are matte tin-plated, compliant with J-STD-002 and JESD 22-B102 soldering standards. Polarity is uni-directional; cathode band denotes the terminal connected to the P-side of the avalanche junction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Current entry during clamping | Connected to protected line (e.g., +12 V rail); conducts surge current toward ground when VIN exceeds VBR. |
| Cathode (banded end) | Current exit during clamping | Connected to reference plane (e.g., chassis ground or power return); completes low-impedance path for transient energy dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable, repeatable avalanche characteristics across temperature and lifetime; eliminates surface leakage drift in humid or contaminated environments. |
| 500 W peak pulse power (10/1000 μs) | Provides sufficient energy absorption for ISO 7637-2 Pulse 1/2a/5a transients in 12 V automotive systems without thermal runaway. |
| AEC-Q101 qualified | Validated for automotive applications including temperature cycling, mechanical shock, and humidity testing-no additional qualification needed for Tier-1 BOMs. |
| Low incremental surge resistance | Minimizes VC – VBR differential (ΔV ≈ 51 V), reducing voltage overshoot during fast-rising transients like ESD or inductive kickback. |
| Solder dip 275 °C / 10 s | Supports lead-free reflow and wave soldering processes without delamination or parameter shift; meets JEDEC J-STD-020 moisture sensitivity level 1. |
Applications
| Automotive Body Control Module (BCM) | Industrial 24 V PLC Input Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A-E3/5T | Same VWM (100 V), lower PPPM (400 W), SMA package (surface-mount), no AEC-Q101 qualification. | Preferred for space-constrained PCBs where reflow assembly is used; unsuitable for under-hood automotive due to missing AEC-Q101. | Select SMAJ100A-E3/5T only if board area is critical and automotive qualification is not required. |
| 1.5KE100A | Higher PPPM (1500 W), DO-201AD package (larger than DO-15), same VWM/VBR range, no AEC-Q101. | Used in high-energy industrial motor drives; requires larger footprint and lacks automotive reliability validation. | Choose 1.5KE100A only when surge energy exceeds 500 W and AEC-Q101 is not mandated. |
Compared with SMAJ100A-E3/5T and 1.5KE100A, SA100-E3/54 uniquely balances automotive-grade qualification, axial through-hole manufacturability, and precise 500 W clamping performance in the compact DO-15 outline-making it optimal for cost-sensitive, high-reliability 12 V–48 V systems requiring legacy-compatible assembly.

FAQ
What is the clamping voltage of SA100-E3/54 at its rated peak pulse current?
The SA100-E3/54 has a maximum clamping voltage (VC) of 162 V at its rated peak pulse current (IPPM) of 3.1 A, measured using the standard 10/1000 μs waveform. This value is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88378 and defines the upper voltage limit imposed on protected circuitry during full-rated transient events. The SA100-E3/54 maintains this clamping performance across its operational temperature range.
Is SA100-E3/54 suitable for automotive applications?
Yes, SA100-E3/54 is AEC-Q101 qualified, as explicitly stated in the "Notes" section on page 3 of Vishay document 88378. It meets the stress test requirements for automotive use-including temperature cycling, mechanical shock, and humidity resistance-making it appropriate for body control modules, infotainment power rails, and ADAS camera power inputs. The SA100-E3/54 is rated for junction temperatures up to +175 °C, supporting under-hood deployment.
What does the "E3/54" suffix indicate in SA100-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance, while "/54" specifies the preferred package code for 13-inch paper tape and reel packaging with a base quantity of 4000 units. This ordering format is defined in the "ORDERING INFORMATION" section on page 3 of Vishay document 88378 and confirms the SA100-E3/54 is supplied in industry-standard automated assembly format.
How does SA100-E3/54 differ from bi-directional SA100CA variants?
SA100-E3/54 is uni-directional with cathode band marking and blocks reverse current until breakdown, whereas SA100CA is bi-directional with no polarity marking and clamps in both directions. The SA100-E3/54 has a forward voltage drop (~3.5 V at 100 A) and supports IFSM = 70 A, while SA100CA omits forward surge rating and exhibits symmetric VBR in both polarities. These distinctions are documented in the "PRIMARY CHARACTERISTICS" and "ELECTRICAL CHARACTERISTICS" tables of Vishay document 88378.
What is the maximum steady-state power dissipation for SA100-E3/54?
The SA100-E3/54 has a maximum steady-state power dissipation (PD) of 3.0 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C, as specified in the "MAXIMUM RATINGS" table on page 1 of Vishay document 88378. This rating assumes ideal thermal conditions; actual PCB layout, copper area, and ambient temperature will reduce usable power. Derating follows the curve in Figure 5, dropping to ~1.5 W at TL = 125 °C.
