Product details
Overview
SA8.0C-E3/73 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 500 W peak pulse power (10/1000 μs), 8.0 V stand-off voltage (VWM), 13.6 V maximum clamping voltage at 25 A (VC), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA8.0C-E3/73 datasheet, SA8.0C-E3/73 pinout, SA8.0C-E3/73 application, or SA8.0C-E3/73 equivalent, this device is selected for robust ESD and surge protection in low-voltage bidirectional interfaces - especially where polarity-agnostic clamping, fast response (<1 ns), and stable TJ = −55 °C to +175 °C operation are required.
Technical Context
The SA8.0C-E3/73 operates as a bi-directional avalanche diode with symmetrical breakdown characteristics in both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and repeatable clamping performance under repetitive surge conditions.
It delivers 500 W peak pulse power per 10/1000 μs waveform at 0.01% duty cycle, with incremental clamping resistance of ~0.22 Ω derived from (VC − VBR)/IPPM, supporting effective energy diversion during lightning-induced or inductive-switching transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold. |
| VBR min/max | 8.89 V / 9.83 V at 1.0 mA - Confirmed breakdown range ensures reliable turn-on across temperature and unit variation. |
| VC @ IPPM | 13.6 V at 25 A - Clamping voltage limits downstream IC stress during 10/1000 μs surges; enables safe interface with 12 V logic or sensors. |
| PPPM | 500 W - Peak transient energy handling capacity; supports IEC 61000-4-5 Level 3 (1 kV/2 Ω) compliance when properly routed. |
| ID @ VWM | <1.0 μA - Ultra-low leakage preserves signal integrity and battery life in always-on sensor nodes. |
| TJ range | −55 °C to +175 °C - Full automotive temperature coverage; validated for under-hood and engine-control module use. |
Pinout & Package
DO-204AC (DO-15) molded epoxy package with matte tin-plated leads; no polarity marking (bi-directional); RoHS-compliant (E3 suffix); UL 94 V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction terminals | No functional distinction - either lead serves as input/output for transient current in either direction; PCB layout requires no orientation check. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Ensures long-term stability of VBR and leakage under thermal cycling and humidity exposure. |
| 500 W peak pulse power (10/1000 μs) | Handles high-energy transients from relay switching or load dump without degradation over 1000+ events. |
| AEC-Q101 qualified | Validated for automotive applications including infotainment, body control modules, and ADAS sensor interfaces. |
| Low incremental surge resistance (~0.22 Ω) | Minimizes voltage overshoot during fast-rising transients (e.g., ESD >15 kV), improving protection margin. |
Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting analog outputs of pressure or temperature sensors in engine control units exposed to load-dump transients up to 35 V. IC Role / Device Role / Timing Role: Bi-directional clamping element placed between sensor output and microcontroller ADC input. Use Value: Maintains signal fidelity by limiting voltage excursions to ≤13.6 V while surviving repeated 500 W pulses per ISO 7637-2 Pulse 5a. | Use Scenario: Safeguarding CANH/CANL lines in vehicle telematics modules against ESD and coupled noise from adjacent high-power circuits. IC Role / Device Role / Timing Role: Low-capacitance (≈100 pF) bi-directional TVS placed differential across CAN bus pair. Use Value: Prevents bus lockup by clamping ±15 kV contact ESD (IEC 61000-4-2) without distorting 1 Mbps CAN signaling. |
| Consumer USB Port Protection | Smart Meter Power Line Interface |
Use Scenario: Shielding USB 2.0 D+/D− lines in portable medical devices from user-handling ESD and cable discharge events. IC Role / Device Role / Timing Role: Symmetrical TVS mounted directly at USB connector, before ESD filter or transceiver. Use Value: Achieves <1 ns response time and sub-1.0 μA leakage to avoid data corruption or false disconnect detection. | Use Scenario: Protecting isolated DC-DC converter inputs in smart electricity meters subjected to surge coupling from AC mains (IEC 61000-4-5). IC Role / Device Role / Timing Role: Primary-level TVS on secondary-side bias rail feeding meter SoC and RTC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A-E3/5A | Uni-directional; same VWM/VC, but requires correct polarity placement and lacks bi-directional symmetry. | Only suitable where circuit ground reference is fixed and signal polarity is known (e.g., single-supply UART lines). | Select only if board layout enforces unidirectional signal flow and polarity alignment can be guaranteed. |
| 1.5KE8.2C | Higher PPPM (1500 W), larger DO-201 package (5.6 mm x 9.5 mm vs. DO-15's 3.6 mm x 7.6 mm), higher VC (13.4 V). | Better for high-energy industrial surges but incompatible with space-constrained automotive PCBs. | Choose when surge energy exceeds 500 W and board area allows larger footprint. |
Compared with SMAJ8.0A-E3/5A and 1.5KE8.2C, the SA8.0C-E3/73 uniquely balances bi-directional functionality, compact DO-15 packaging, and AEC-Q101 qualification - making it optimal for automotive and space-limited bidirectional interfaces where polarity-agnostic protection is mandatory.

FAQ
What is the polarity configuration of the SA8.0C-E3/73?
The SA8.0C-E3/73 is a bi-directional TVS diode with symmetrical avalanche characteristics in both directions. It has no cathode marking and functions identically regardless of terminal orientation - ideal for protecting AC-coupled or floating signal lines where polarity cannot be assumed. This distinguishes it from uni-directional variants like SA8.0A-E3/73.
Does the SA8.0C-E3/73 meet AEC-Q101 requirements?
Yes, the SA8.0C-E3/73 is AEC-Q101 qualified, as confirmed in Vishay document 88378 (Revision: 18-Sep-12). This qualification covers stress tests including HTGB, HTRB, TCT, and mechanical shock - validating its suitability for automotive powertrain, chassis, and body electronics applications.
What is the maximum clamping voltage of the SA8.0C-E3/73 at rated peak pulse current?
The SA8.0C-E3/73 has a maximum clamping voltage (VC) of 13.6 V at 25 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per standard test methods and ensures predictable voltage limiting during surge events in 12 V system environments.
Can the SA8.0C-E3/73 be used in place of a uni-directional TVS like SA8.0A-E3/73?
No - the SA8.0C-E3/73 is bi-directional and lacks polarity marking, while SA8.0A-E3/73 is uni-directional with a defined cathode band. Substituting them requires verifying circuit topology: SA8.0C-E3/73 is appropriate for AC or floating nodes; SA8.0A-E3/73 must be oriented correctly in DC-biased paths. Direct replacement is not electrically or mechanically identical.
What is the leakage current specification for the SA8.0C-E3/73 at its stand-off voltage?
The SA8.0C-E3/73 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its 8.0 V stand-off voltage (VWM), measured at TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and extends battery life in always-on IoT endpoints.
