Product details
Overview
SA100CHE3/54 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), 500 W peak pulse power (10/1000 µs), 3.1 A peak pulse current (IPPM), and clamps to ≤162 V at rated surge. It is AEC-Q101 qualified and used for protecting automotive sensor interfaces against ESD and load-dump events.
For engineers reviewing the SA100CHE3/54 datasheet, SA100CHE3/54 pinout, SA100CHE3/54 application, or SA100CHE3/54 equivalent, this page delivers verified electrical specs, mechanical package data, real-world protection use cases, and validated alternative parts - all aligned with Vishay's 88378 specification document dated 18-Sep-12.
Technical Context
The SA100CHE3/54 operates as a bi-directional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its silicon junction is glass passivated for stable leakage and long-term reliability under repetitive surge stress.
It delivers 500 W peak pulse power per 10/1000 µs waveform at TA = 25 °C, derating linearly above 25 °C per Figure 2, with maximum junction temperature of 175 °C and storage range from –55 °C to +175 °C. Clamping occurs within picoseconds, with low incremental surge resistance ensuring minimal voltage overshoot during fast transients.
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 avalanche onset range; ensures predictable turn-on across production lot and temperature. |
| IPPM | 3.1 A - Peak surge current it safely shunts during 10/1000 µs transient; directly determines protected line impedance compatibility. |
| VC @ IPPM | ≤162 V - Maximum clamped voltage under full-rated surge; defines worst-case overvoltage seen by downstream ICs. |
| PPPM | 500 W - Surge energy handling capacity per single 10/1000 µs pulse; enables robust protection against ISO 7637-2 Pulse 1/2a/5a. |
| TJ max | 175 °C - Maximum junction temperature rating; supports operation in under-hood automotive environments. |
| Qualification | AEC-Q101 qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance. |

Applications
| Automotive Sensor Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting 12 V supply and signal lines of wheel speed sensors and pressure transducers exposed to ISO 7637-2 Pulse 5a (load dump). IC Role / Device Role / Timing Role: Bi-directional TVS placed between signal line and ground, clamping surges before they reach ASIC front-end. Use Value: Limits transient voltage to ≤162 V, preserving integrity of 100 V-rated op-amps and ADC inputs in harsh vehicle environments. |
Use Scenario: Safeguarding 4–20 mA current loop inputs in programmable logic controllers subjected to field wiring-induced surges. IC Role / Device Role / Timing Role: Standoff-rated TVS mounted at terminal block entry point, absorbing induced lightning-like transients on long cable runs. Use Value: Maintains <1 µA leakage at 100 V, preventing offset errors in precision current measurement circuits. |
| Telecom Line Card Surge Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Secondary-level protection on AC-powered telecom line cards where primary MOVs handle bulk energy but require fast-response backup. IC Role / Device Role / Timing Role: Fast-acting bi-directional clamp parallel to data line (e.g., RS-485), triggered within <1 ns. Use Value: Complements slower primary protectors by suppressing residual high-frequency ringing and ESD spikes up to ±15 kV contact discharge. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in washing machines and HVAC blowers connected to microcontroller I/O. IC Role / Device Role / Timing Role: Mounted across motor terminals or between MCU GPIO and driver FET gate, limiting inductive kickback. Use Value: Withstands 70 A non-repetitive forward surge (IFSM), enabling direct placement on motor drive paths without series fusing. |
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-E3/54 | Uni-directional; 100 V VWM, 111–123 V VBR, same DO-214AC package but surface-mount; lower IPPM (3.0 A vs. 3.1 A). | Requires polarity-aware layout; unsuitable for AC-coupled or floating signal lines where bi-directionality is mandatory. | Select when board space is constrained and circuit topology guarantees unidirectional bias; verify grounding scheme excludes reverse conduction risk. |
| 1.5KE100CA | Higher PPPM (1500 W), same bi-directional DO-201AD package; larger footprint; VC = 165 V at 9.3 A. | Better suited for primary-level protection in high-energy systems (e.g., alternator output); less precise clamping due to higher VC/VBR ratio. | Choose when system-level surge testing exceeds 500 W requirements; accept larger size and reduced layout density for enhanced margin. |
Compared with SMAJ100A-E3/54 and 1.5KE100CA, the SA100CHE3/54 uniquely combines AEC-Q101 qualification, bi-directional symmetry, and DO-15 through-hole compatibility - making it optimal for automotive and industrial designs needing proven reliability, polarity-agnostic placement, and legacy-compatible assembly.

FAQ
What is the clamping voltage of SA100CHE3/54 at its rated peak pulse current?
The SA100CHE3/54 has a maximum clamping voltage (VC) of 162 V when subjected to its rated peak pulse current of 3.1 A (10/1000 µs waveform). This value is measured per Figure 7 in Vishay document 88378 and defines the upper limit of voltage imposed on protected circuitry during surge events. The SA100CHE3/54 maintains this clamping performance across its qualified temperature range.
Is SA100CHE3/54 suitable for automotive applications?
Yes, the SA100CHE3/54 is AEC-Q101 qualified per Vishay documentation, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its DO-204AC package, 175 °C junction rating, and validated surge endurance make the SA100CHE3/54 appropriate for under-hood and chassis-mounted systems subject to rigorous environmental stress.
Does SA100CHE3/54 have polarity markings?
No, the SA100CHE3/54 is a bi-directional TVS diode and carries no polarity marking on its DO-204AC package. Unlike uni-directional variants (e.g., SA100A), it functions identically regardless of terminal orientation - critical for protecting AC-coupled signals or floating bus lines. This symmetry is confirmed in the "Polarity" section of Vishay document 88378.
What is the maximum steady-state power dissipation for SA100CHE3/54?
The SA100CHE3/54 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 of Vishay document 88378. Derating is required above 75 °C per Figure 5, and actual PCB layout must ensure adequate copper area and lead length (≥0.375") to maintain thermal performance.
How does the HE3 suffix affect the SA100CHE3/54 specification?
HE3 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - distinguishing it from commercial-grade E3 variants. The SA100CHE3/54 HE3 suffix confirms compliance with automotive material standards (document 99912) and extended reliability testing, while retaining identical electrical parameters as the base SA100CA part.
