Product details
Overview
SA10CA from Taiwan Semiconductor is a unidirectional 500W transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, with 10V working stand-off voltage (VWM), 11.1–13.6V breakdown voltage (VBR @ 1mA), and 17.0V maximum clamping voltage (VC) at 30A peak pulse current. It delivers fast response (<1.0ps), low leakage (<1μA @ 10V), and AEC-Q101 qualification for automotive-grade surge protection.
For engineers reviewing the SA10CA datasheet, SA10CA pinout, SA10CA application, or SA10CA equivalent, this page provides verified electrical parameters, mechanical package details, real-world use cases in automotive and industrial systems, and validated alternative parts for ESD and inductive switching protection design.
Technical Context
The SA10CA operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its VBR range (11.1–13.6V). Its low dynamic impedance enables rapid clamping to ≤17.0V under 30A 10/1000μs surge, limiting energy delivered to downstream circuitry.
Designed for high-reliability environments, it features pure tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and meets JESD201 Class 2 whisker resistance. Junction temperature range spans –55°C to +175°C, supporting under-hood automotive deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before conduction begins; defines safe signal integrity margin in normal operation. |
| VBR @ IT=1mA | 11.1–13.6 V - Breakdown onset range; ensures predictable turn-on during transients without premature leakage. |
| VC @ IPPM=30A | 17.0 V - Clamped voltage under 500W 10/1000μs surge; directly limits stress on protected ICs like CAN transceivers or microcontrollers. |
| PPK | 500 W - Peak pulse power rating per 10/1000μs waveform; validates robustness against IEC 61000-4-5 Level 4 surges. |
| IR @ VWM | <1 μA - Reverse leakage at 10V; minimizes standby power loss and avoids false triggering in low-power sensor circuits. |
| TJ max | +175 °C - Maximum junction temperature; supports placement near heat sources in engine control units or lighting modules. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with 0.400g mass; compatible with legacy through-hole assembly and automated tape-and-reel handling (3500/reel). |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking polarity. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance. Case meets UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current path / low-side reference | Connected to ground or low-voltage rail; forms return path during clamping event. |
| Cathode | Protected line input / high-side connection | Connected to signal/power line being protected; absorbs surge energy into ground via anode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including powertrain and body electronics per stress test requirements. |
| 500W surge capability | Withstands 10/1000μs transients up to 500W without degradation-meets ISO 7637-2 Pulse 3b and IEC 61000-4-5 requirements. |
| <1.0ps response time | Sub-picosecond turn-on ensures protection of high-speed interfaces (e.g., LIN, CAN FD) before transient energy couples into IC pins. |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained supply chains. |
| Low clamping ratio (VC/VBR ≈ 1.3) | High efficiency in energy diversion: clamps at only ~1.3× breakdown voltage, minimizing voltage overshoot across protected nodes. |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12V battery-fed ECUs from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp positive-going surges above 10V. Use Value: Limits peak rail voltage to ≤17.0V during 30A surges, preventing latch-up or gate oxide damage in MCU power domains. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) connected to ADC inputs in PLC modules. IC Role / Device Role / Timing Role: TVS shunt device on signal line to divert ESD and cable discharge events before reaching precision amplifier front-end. Use Value: Sub-1μA leakage preserves signal accuracy; <1.0ps response prevents transient-induced offset drift or ADC saturation. |
| LED Driver Output Protection | Communication Bus Line Protection |
Use Scenario: Shielding constant-current LED driver outputs from inductive kickback when driving solenoids or relays on shared PCBs. IC Role / Device Role / Timing Role: Unidirectional TVS connected cathode-to-output, anode-to-ground to absorb reverse EMF spikes. Use Value: Withstands 70A non-repetitive forward surge (IFSM), enabling reliable suppression of >100mJ inductive energy without failure. | Use Scenario: Adding surge immunity to LIN bus lines in vehicle door modules exposed to EFT and ESD. IC Role / Device Role / Timing Role: Low-capacitance TVS on LIN data line to clamp transients while preserving signal rise/fall times. Use Value: Clamps to 17.0V within picoseconds, maintaining LIN physical layer compliance (ISO 17987-4) under 1kV EFT bursts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same DO-214AC package; slightly higher VBR (11.1–12.3V), identical VC (17.0V), lower PPK (400W). | Lower surge rating makes it less suitable for ISO 7637-2 Pulse 5a load dump; better for cost-sensitive consumer-grade designs. | Select SMAJ10A only if system-level surge testing confirms 400W sufficiency and board space requires surface-mount footprint. |
| P6SMB10A | DO-214AA package; VBR 11.1–12.3V, VC 17.0V, PPK 600W, but higher IR (≤5μA @ 10V). | Higher power rating suits harsher industrial environments; elevated leakage may affect ultra-low-power sensor bias networks. | Prefer P6SMB10A where 600W margin is required and leakage tolerance allows ≥5μA reverse current. |
Compared with SMAJ10A and P6SMB10A, the SA10CA uniquely combines AEC-Q101 qualification, 500W rating, and sub-1μA leakage in a DO-204AC through-hole package-making it optimal for automotive ECU power rail protection where reliability, legacy assembly compatibility, and low standby current are jointly critical.

FAQ
What is the breakdown voltage range of the SA10CA?
The SA10CA has a minimum breakdown voltage (VBR) of 11.1 V and a maximum of 13.6 V at 1 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent turn-on behavior across production lots while accommodating process variation-critical for predictable clamping in safety-critical automotive circuits where the SA10CA is deployed.
Is the SA10CA suitable for bidirectional transient protection?
No, the SA10CA is a unidirectional TVS diode, indicated by the "CA" suffix and cathode band marking. It protects against positive-going transients on the cathode side only. For bidirectional protection, select SA10C (which lacks the "A" suffix and supports symmetrical clamping); the SA10CA must be used with correct polarity alignment in DC-biased applications.
Does the SA10CA meet automotive qualification standards?
Yes, the SA10CA is AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor SA Series datasheet (Version L2105). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD-validating its suitability for under-hood and chassis-mounted automotive electronics where the SA10CA is commonly applied.
What is the maximum clamping voltage of the SA10CA at rated surge current?
The SA10CA clamps to a maximum of 17.0 V at 30 A peak pulse current (IPPM), corresponding to the standard 10/1000 μs waveform. This VC value is guaranteed across the full operating temperature range and directly determines the voltage stress imposed on downstream components-making it a key parameter when selecting the SA10CA for protecting 12V logic rails or CAN transceivers.
Can the SA10CA be used in surface-mount designs?
No, the SA10CA uses the DO-204AC (DO-15) axial leaded package and is intended for through-hole mounting. It is not compatible with SMT reflow processes. For surface-mount equivalents, consider SMAJ10A (DO-214AC) or SMCJ10A (DO-214AB); however, those parts differ in thermal performance, surge rating, and qualification status compared to the SA10CA.
