Product details
Overview
SA100HE3/54 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 a 100 V stand-off voltage (VWM), 123 V maximum clamping voltage (VC) at 3.1 A peak pulse current (IPPM), 500 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive use.
For engineers reviewing the SA100HE3/54 datasheet, SA100HE3/54 pinout, SA100HE3/54 application, or SA100HE3/54 equivalent, this device is selected for robust overvoltage protection in automotive sensor interfaces, industrial I/O lines, and telecom line cards where bidirectional surge immunity and high-temperature operation up to 175 °C are required.
Technical Context
The SA100HE3/54 operates as a bi-directional avalanche diode with symmetrical breakdown behavior in both polarities, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and low incremental surge resistance, critical for consistent clamping under repetitive transients.
It delivers 500 W peak pulse power handling per the 10/1000 μs waveform standard, with thermal derating above 25 °C ambient and full operational capability from –55 °C to +175 °C junction temperature - validated per AEC-Q101 stress testing including temperature cycling, HTRB, and ESD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 100 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 111–123 V at 1 mA - Confirmed symmetric breakdown threshold in both directions; ensures predictable turn-on. |
| VC (Clamping Voltage) | 162 V at IPPM = 3.1 A - Measured peak voltage during 10/1000 μs transient; determines protected circuit's maximum stress level. |
| PPPM (Peak Pulse Power) | 500 W - Sustains standardized lightning/surge pulses without failure; enables IEC 61000-4-5 Level 4 compliance with proper layout. |
| ID (Reverse Leakage) | ≤1.0 μA at 100 V - Minimal standby current; avoids signal distortion or battery drain in always-on circuits. |
| TJ max. | 175 °C - Enables placement near hot components (e.g., power MOSFETs, engine control units) without thermal derating loss. |
| AEC-Q101 Qualified | Yes - Validated for automotive underhood and chassis applications per stress test requirements (HTGB, TCT, H3TRB). |
Pinout & Package
SA100HE3/54 uses the DO-204AC (DO-15) axial-leaded package: molded epoxy case with matte tin-plated leads, UL 94 V-0 rated, 0.300" (7.6 mm) minimum lead length, 0.140" (3.6 mm) max body diameter. Bi-directional construction means no polarity marking; both terminals are functionally identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (both ends) | Bi-directional avalanche junction terminal | Either end connects to protected line; no cathode band - symmetric conduction in positive/negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Ensures stable VBR over lifetime and humidity exposure; eliminates passivation-related leakage drift in harsh environments. |
| 500 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 combination wave surges up to 4 kV (line-earth) when used with series impedance ≥2 Ω. |
| AEC-Q101 qualification | Validated for automotive Grade 0 (–40 to +150 °C ambient) and Grade 1 (–40 to +125 °C) applications with zero early-life failures. |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes overvoltage overshoot during fast transients; improves margin for 12 V or 24 V system ICs with 150 V absolute max ratings. |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance; suitable for reflow and wave soldering with 275 °C/10 s max solder dip tolerance. |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|

| Telecom Line Card Protection | Power Supply Inrush & Surge Clamp |
Use Scenario: Safeguarding Ethernet PHY front-end and xDSL line drivers from lightning-induced common-mode transients on twisted-pair lines. IC Role / Device Role / Timing Role: Bi-directional TVS mounted across transformer secondary or directly on line-side pins to suppress ±1 kV ring wave surges. Use Value: Symmetric clamping ensures equal protection for positive and negative half-cycles; 175 °C TJ rating supports compact board layouts near heat-generating PHY ICs. |
Use Scenario: Supplementing MOV-based AC input protection by clamping fast-rising switch-mode power supply turn-on spikes and capacitor inrush overshoot. IC Role / Device Role / Timing Role: Fast-response secondary clamp on DC bus or rectified output to catch sub-microsecond transients missed by slower MOVs. Use Value: 10/1000 μs response captures high-dI/dt events from relay bounce or MOSFET commutation; 500 W rating handles repeated 100 A surge peaks without degradation. |
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, 165 V VC at 3.0 A; same DO-214AC package but surface-mount. | Requires polarity-aware layout; unsuitable for AC or floating lines without external biasing. | Select only if board space constraints mandate SMD and circuit topology guarantees unidirectional stress. |
| 1.5KE100CA | Same bi-directional function; 100 V VWM, 165 V VC at 3.0 A; larger DO-201AD package (higher thermal mass). | Higher IFSM (100 A vs. 70 A) but lower power density; less suitable for dense automotive PCBs. | Prefer for high-reliability industrial power supplies where mechanical robustness and surge repetition rate exceed SA100HE3/54 limits. |
Compared with SMAJ100A-E3/54 and 1.5KE100CA, the SA100HE3/54 offers AEC-Q101 qualification and axial-leaded DO-15 form factor ideal for through-hole automotive harness interfaces, while maintaining tighter clamping (162 V vs. 165 V) and lower thermal resistance than legacy 1.5KE series.

FAQ
What is the polarity configuration of SA100HE3/54?
The SA100HE3/54 is a bi-directional TVS diode with no polarity marking on the DO-204AC package. Both terminals are functionally identical, allowing it to clamp voltage transients of either polarity symmetrically - essential for protecting AC-coupled signals, transformer-isolated interfaces, or floating bus lines without orientation constraints.
Does SA100HE3/54 meet automotive qualification standards?
Yes, the SA100HE3/54 carries the HE3 suffix, indicating full AEC-Q101 qualification. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling (TCT), and unbiased highly accelerated temperature/humidity stress (UHAST), making it suitable for under-hood and chassis-mounted automotive applications per Grade 0 and Grade 1 requirements.
What is the maximum clamping voltage of SA100HE3/54 under standard surge conditions?
The SA100HE3/54 exhibits a maximum clamping voltage (VC) of 162 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 3.1 A. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events.
Can SA100HE3/54 be used in place of a uni-directional TVS like SA100A?
No - the SA100HE3/54 is bi-directional and lacks a defined cathode, whereas SA100A is uni-directional with a marked cathode band. Substituting SA100HE3/54 for SA100A in DC-biased circuits may cause unintended conduction; replacement requires verifying circuit topology supports symmetrical clamping and absence of steady-state reverse bias exceeding VWM.
What packaging and reel format does SA100HE3/54 ship in?
The SA100HE3/54 ships in 13-inch diameter paper tape and reel format with a base quantity of 4000 units per reel (package code 54). The leads are matte tin-plated and compliant with J-STD-002 and JESD 22-B102 solderability standards, supporting both wave and selective soldering processes.
