Product details
Overview
SA10CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 500 W peak pulse power (10/1000 μs), 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage at 29.4 A peak pulse current, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SA10CA-E3/54 datasheet, SA10CA-E3/54 pinout, SA10CA-E3/54 application, or SA10CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 10 V stand-off rating, low clamping ratio (VC/VWM = 1.7), and compliance with automotive reliability standards.
Technical Context
The SA10CA-E3/54 operates as a voltage-clamping protection device that conducts above its breakdown voltage (VBR = 11.1–12.3 V at 1 mA) to divert surge energy away from sensitive circuitry. Its bidirectional symmetry ensures identical clamping behavior in both polarities, eliminating polarity marking requirements.
It delivers 500 W peak pulse power per 10/1000 μs waveform with <1 ns response time and low incremental surge resistance - critical for protecting MOSFET gates, sensor interfaces, and microcontroller I/O lines against ESD and inductive switching transients.
Key Specifications

| VBR (min/max) | 11.1 V / 12.3 V at 1 mA - Ensures reliable triggering across temperature and process variation |
| VC @ IPPM | 17.0 V at 29.4 A - Clamping voltage under full 500 W transient load; defines protected circuit's max stress |
| PPPM | 500 W - Peak surge power handling per 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 |
| IPPM | 29.4 A - Corresponding peak pulse current at rated clamping voltage |
| TJ max | +175 °C - Enables operation in under-hood automotive environments and industrial enclosures |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package

| Low clamping ratio (VC/VWM = 1.7) | Minimizes overvoltage exposure to downstream ICs during transient events |
| UL 94 V-0 molding compound | Ensures flame-retardant enclosure integrity in safety-critical systems |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt transients before reaching signal conditioning circuitry. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V microcontrollers and precision ADCs by limiting voltage to ≤17.0 V during 500 W surges. | Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Standoff voltage (10 V) aligns with 24 V DC industrial logic thresholds; clamps fast-rising transients (<1 ns) before propagation into optocoupler or Schmitt trigger stages. Use Value: Eliminates need for external series impedance or RC filtering while maintaining signal integrity for 1 kHz–10 kHz digital inputs. |
| Consumer Power Adapter Interface | Telecom Line Card Surge Protection |
Use Scenario: Input-stage protection for USB-C PD adapters and AC/DC converters subject to lightning-induced surges on primary-side rectifier outputs. IC Role / Device Role / Timing Role: Secondary-side TVS placed across bulk capacitor to clamp overshoot during startup or line fault conditions. Use Value: Withstands repetitive 500 W pulses at 0.01% duty cycle, enabling robust design without thermal derating concerns in compact enclosures. | Use Scenario: Primary protection for Ethernet PHY interfaces and DSL line drivers subjected to induced surges per GR-1089-CORE. IC Role / Device Role / Timing Role: Bidirectional clamping between differential pairs (e.g., TX+/TX−) to maintain common-mode rejection during surge events. Use Value: Symmetric VBR (11.1–12.3 V) ensures balanced clamping without skew, preserving signal timing margins in high-speed data links. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V), lower PPPM (400 W), SMA package (smaller footprint, lower thermal mass) | Better suited for space-constrained consumer PCBs; reduced surge margin for industrial environments | Select when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 3 |
| 1.5KE10CA | Same VWM (10 V), higher PPPM (1500 W), DO-201 package (larger, higher thermal inertia) | Required for high-energy lightning surge zones (e.g., outdoor telecom cabinets); longer lead time and cost premium | Select when system-level testing requires >500 W clamping headroom or extended thermal hold time |
Compared with SMAJ10CA and 1.5KE10CA, the SA10CA-E3/54 offers optimal balance of automotive qualification, DO-15 manufacturability, and 500 W surge capacity - making it preferred for cost-sensitive, volume automotive and industrial designs where AEC-Q101 compliance and standard through-hole assembly are mandatory.

FAQ
What is the breakdown voltage range of the SA10CA-E3/54?
The SA10CA-E3/54 has a minimum breakdown voltage (VBR) of 11.1 V and a maximum of 12.3 V at 1 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent clamping initiation across manufacturing lots and temperature extremes, and is confirmed in Vishay document 88378, page 2.
Is the SA10CA-E3/54 suitable for automotive applications?
Yes, the SA10CA-E3/54 is AEC-Q101 qualified (note on page 3 of Vishay document 88378), with validated performance across -55 °C to +175 °C junction temperature, humidity, and mechanical stress tests. Its DO-15 package and bidirectional clamping make it appropriate for engine control, body electronics, and ADAS sensor protection where SA10CA-E3/54 replaces legacy unidirectional parts without redesign.
What is the maximum clamping voltage of the SA10CA-E3/54 under surge conditions?
The SA10CA-E3/54 exhibits a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current of 29.4 A (10/1000 μs waveform). This value is specified in the Electrical Characteristics table (page 2 of Vishay document 88378) and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Does the SA10CA-E3/54 have polarity markings?
No, the SA10CA-E3/54 is a bidirectional TVS diode and carries no polarity marking - both terminals are functionally identical. As stated in the Mechanical Data section (page 1), "no marking on bidirectional types," which simplifies placement and eliminates orientation errors during automated assembly of SA10CA-E3/54 on production lines.
What package type does the SA10CA-E3/54 use, and what are its key mechanical features?
The SA10CA-E3/54 uses the DO-15 (DO-204AC) package: axial-leaded, epoxy-molded, UL 94 V-0 rated, with matte tin-plated leads compliant with J-STD-002. Dimensions include 0.130–0.138 inch diameter and ≥1.0 inch lead length; these mechanical attributes ensure compatibility with standard through-hole reflow and wave solder processes used for SA10CA-E3/54 in high-volume manufacturing.
