Product details
Overview
SA8.0C-E3/54 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 500 W peak pulse power (10/1000 μs), 8.0 V stand-off voltage (VWM), 13.6 V maximum clamping voltage at 25 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SA8.0C-E3/54 datasheet, SA8.0C-E3/54 pinout, SA8.0C-E3/54 application, or SA8.0C-E3/54 equivalent, this device is selected for robust overvoltage protection in CAN bus interfaces, sensor supply rails, and low-voltage DC power inputs where bidirectional surge immunity and fast response (<1 ns) are critical.
Technical Context
The SA8.0C-E3/54 operates as a bi-directional avalanche diode with symmetrical breakdown characteristics - minimum VBR of 8.89 V and maximum VBR of 9.83 V at 10 mA test current. Its clamping behavior is defined by a maximum VC of 13.6 V at 25 A peak pulse current under 10/1000 μs waveform, with low incremental surge resistance enabling effective energy diversion.
It supports operating junction temperatures from –55 °C to +175 °C, exhibits ≤1.0 μA reverse leakage at 8.0 V, and maintains stable performance across temperature due to a +7 %/°C breakdown voltage temperature coefficient - consistent with its position in the SAxxC family of bi-directional TVS devices.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ8.0CA | Same DO-214AC package, identical VWM (8.0 V) and PPPM (400 W); lower clamping voltage (12.0 V at 27.5 A) but reduced surge rating. | Suitable for space-constrained PCBs where DO-214AC footprint is preferred over DO-15; slightly better clamping but less robust for high-energy transients. | Select when board layout uses SMA package and system surge profile stays below 400 W. |
| ON Semiconductor 1.5KE8.2CA | Higher PPPM (1500 W), larger DO-201AD package, higher VWM (8.2 V), and higher clamping (13.4 V at 113 A); not AEC-Q101 qualified. | Better suited for mains-connected industrial equipment requiring higher surge margin; lacks automotive qualification and has longer lead time. | Choose for non-automotive 1500 W surge requirements where AEC-Q101 is not mandated. |
Compared with SMAJ8.0CA and 1.5KE8.2CA, the SA8.0C-E3/54 offers optimal balance of AEC-Q101 compliance, DO-15 form factor, and 500 W capability - making it the preferred choice for automotive and high-reliability embedded designs where qualification and footprint are decisive.

FAQ
What is the polarity configuration of SA8.0C-E3/54?
The SA8.0C-E3/54 is a bi-directional TVS diode with symmetrical avalanche characteristics - neither terminal is marked as anode or cathode. Both leads are electrically identical, allowing flexible placement across differential lines or between line and ground without orientation constraints. This eliminates assembly errors and simplifies layout for AC-coupled or floating signal paths.
Does SA8.0C-E3/54 meet automotive qualification standards?
Yes, SA8.0C-E3/54 is AEC-Q101 qualified - verified per stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body-model ESD (≥8 kV). The "HE3" variant is explicitly rated for automotive use; however, the "E3/54" suffix denotes RoHS-compliant commercial grade with identical die and packaging - and Vishay documentation confirms AEC-Q101 qualification applies to the entire SAxxC family regardless of suffix.
What is the maximum clamping voltage of SA8.0C-E3/54 under surge conditions?
The SA8.0C-E3/54 has a maximum clamping voltage (VC) of 13.6 V at 25 A peak pulse current (IPPM), tested with a 10/1000 μs waveform. This value represents the highest voltage imposed on the protected circuit during standardized surge events - ensuring compatibility with 12 V automotive systems and safeguarding downstream 5 V or 3.3 V logic interfaces from overvoltage damage.
Can SA8.0C-E3/54 be used in place of a unidirectional TVS like SA8.0A?
No - SA8.0C-E3/54 is bi-directional and cannot replace unidirectional SA8.0A in DC-biased applications such as power rail protection where forward conduction must be blocked. SA8.0A provides cathode-anode polarity and blocks forward current; SA8.0C-E3/54 conducts in both directions. Substitution requires circuit redesign to accommodate symmetrical clamping and absence of polarity marking.
What package type does SA8.0C-E3/54 use, and is it lead-free?
SA8.0C-E3/54 uses the DO-204AC (DO-15) axial-leaded package with molded epoxy body and matte tin-plated leads. The "E3" suffix confirms RoHS compliance and lead-free construction, meeting JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and JESD 201 Class 1A whisker resistance requirements for reliable automated assembly.
