Product details
Overview
SA10CAH from Taiwan Semiconductor is a bidirectional AEC-Q101-qualified transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, rated for 500W peak pulse power at 10/1000μs, with 10V working stand-off voltage (VWM), 11.1–13.6V breakdown voltage (VBR), and 17.0V maximum clamping voltage (VC) at 30A peak pulse current - deployed for ESD and load-dump protection in automotive lighting and powertrain control modules.
For engineers reviewing the SA10CAH datasheet, SA10CAH pinout, SA10CAH application, or SA10CAH equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, AEC-Q101 qualification status, DO-15 mechanical interface details, and direct alternatives for automotive-grade transient suppression design.
Technical Context
The SA10CAH operates as a bidirectional avalanche diode, symmetrically clamping transients above ±11.1V in both polarities with sub-nanosecond response (<5.0ns). Its 10V VWM ensures compatibility with 12V automotive supply rails while maintaining low leakage (<1μA at VWM).
It sustains 70A non-repetitive forward surge current (IFSM) and 30A peak pulse current (IPPM) under 10/1000μs waveform, with thermal derating to 175°C junction temperature and UL 94V-0 molding compound - meeting stringent automotive reliability requirements per JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; matches nominal 12V system rail with margin. |
| VBR (min/max) | 11.1 / 13.6 V - Breakdown occurs within this range at 1mA test current; defines precise clamping onset threshold. |
| VC @ IPPM | 17.0 V at 30 A - Maximum voltage seen across device during 10/1000μs surge; limits stress on downstream ICs. |
| PPK | 500 W - Peak pulse power handling capability per single 10/1000μs transient; validated per ANSI/IEEE C62.35. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| IR @ VWM | <1 μA - Reverse leakage at 10V; ensures minimal standby power loss and signal integrity in high-impedance circuits. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with tin-plated leads, UL 94V-0 rated epoxy. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded plastic case with cathode band marking for unidirectional variants; SA10CAH is bidirectional and marked without polarity band per datasheet specification. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | No functional polarity - terminals interchangeable; clamps positive and negative transients identically. |
| Lead 1 / Lead 2 | Connection to PCB pads | Each lead connects to system ground or protected line; requires 10×10 mm copper pads for full 3W steady-state dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including temperature cycling, humidity bias, and mechanical shock per stress test requirements. |
| Bidirectional clamping | Identical VBR (11.1–13.6V) and VC (17.0V) in both directions - eliminates need for external polarity management in DC bus protection. |
| Low clamping ratio (VC/VBR) | 1.53 typical (17.0V / 11.1V) - minimizes overvoltage exposure during fast transients compared to higher-ratio suppressors. |
| Sub-5ns response time | <5.0 ns from 0V to VBR - intercepts EFT and ISO 7637-2 pulses before sensitive logic or analog circuitry reacts. |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive - supports environmentally compliant automotive manufacturing. |
Applications
| Automotive Lighting Control | Engine Control Unit (ECU) Power Input |
|---|---|
Use Scenario: Protecting LED driver ICs and microcontrollers from load-dump spikes (up to +35V) and alternator ripple in headlamp modules. IC Role / Device Role: Primary transient clamp on 12V supply rail upstream of DC-DC converters and gate drivers. Use Value: Limits voltage excursion to ≤17.0V during 500W surges, preventing latch-up or oxide breakdown in 3.3V/5V logic. |
Use Scenario: Safeguarding MCU power pins and CAN transceiver VCC against ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 5a (load dump). IC Role / Device Role: Bidirectional rail clamp placed between battery feed and local LDO input. Use Value: Maintains system uptime by clamping transients before they exceed 17.0V - below absolute maximum ratings of most automotive MCUs. |
| Body Control Module (BCM) LIN Bus | Electric Power Steering (EPS) Sensor Interface |
Use Scenario: Shielding LIN transceivers from ESD events (IEC 61000-4-2 ±8kV contact) and board-level coupling noise. IC Role / Device Role: Low-capacitance TVS on LIN data line (VBAT-referenced), leveraging bidirectional symmetry for shared ground architecture. Use Value: Sub-5ns response ensures clamping occurs before LIN physical layer receiver damage threshold is exceeded. |
Use Scenario: Protecting Hall-effect position sensors and analog front-ends from coupled transients during motor commutation in EPS motor control boards. IC Role / Device Role: Secondary clamp on sensor VDD line, complementing primary rail protection with localized low-leakage (<1μA) hold-off. Use Value: 10V VWM avoids false triggering during normal 12V supply variation while enabling clean 5V sensor regulation. |
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 SMAJ10CA | Same DO-214AC package, identical 10V VWM and 17.0V VC@30A, but rated for 400W PPK (vs. SA10CAH's 500W). | Lower peak power margin may limit suitability in high-energy load-dump scenarios per ISO 16750-2. | Select SMAJ10CA only if system-level surge energy is confirmed ≤400W; otherwise SA10CAH provides higher safety margin. |
| ON Semiconductor 1.5KE10CA | DO-201AD package (larger than DO-15), 10V VWM, 17.0V VC@30A, 1500W PPK - significantly higher power rating but incompatible footprint. | Requires PCB redesign due to larger case size and different lead spacing; not drop-in. | Choose 1.5KE10CA only when surge energy exceeds 500W and layout revision is feasible; SA10CAH fits space-constrained automotive modules. |
Compared with SMAJ10CA and 1.5KE10CA, SA10CAH uniquely balances 500W surge capacity, DO-15 compactness, and AEC-Q101 qualification - making it optimal for cost-sensitive, space-limited automotive electronics where full 1.5kW devices are over-specified and 400W alternatives lack margin.

FAQ
What does the "CA" suffix indicate in SA10CAH?
The "CA" in SA10CAH denotes bidirectional configuration - meaning the device clamps transients of either polarity symmetrically. Unlike unidirectional "A" variants (e.g., SA10A), SA10CAH has no cathode band marking and functions identically in both directions, making it ideal for AC-coupled or floating-rail protection such as LIN bus or differential sensor lines.
Is SA10CAH compatible with lead-free reflow soldering processes?
Yes, SA10CAH uses pure tin-plated leads compliant with J-STD-002 and qualified for lead-free reflow profiles up to 260°C peak temperature. The DO-204AC (DO-15) package's UL 94V-0 epoxy withstands standard IPC/JEDEC J-STD-020 moisture sensitivity level 1 conditions without preconditioning.
How does SA10CAH's 500W rating compare to standard 400W TVS diodes in automotive use?
SA10CAH's 500W peak pulse power (at 10/1000μs) provides 25% higher surge energy handling than typical 400W devices like SMAJ10CA - directly improving robustness against severe load-dump events defined in ISO 16750-2 Test 4a (up to 120V, 200ms). This margin reduces field failure risk in 12V battery systems with high alternator output.
Does SA10CAH require heatsinking for continuous operation?
No additional heatsink is required for transient suppression duty cycles. SA10CAH's 3W steady-state power dissipation (PD) is rated at TL = 75°C with 9.5mm lead lengths mounted on 10×10 mm copper pads - sufficient for automotive ambient conditions. Continuous DC power dissipation is not a design use case; the device operates in clamping mode only during transient events.
Can SA10CAH be used in industrial 24V systems?
SA10CAH is optimized for 12V automotive systems (VWM = 10V), making it unsuitable for direct use on 24V rails - its 10V stand-off would cause premature conduction during normal operation. For 24V applications, select SA24CAH (VWM = 24V, VBR = 26.7–32.6V) or SA26CAH to maintain proper margin above nominal supply voltage.
