Product details
Overview
SA60CA from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, rated for 500W peak pulse power at 10/1000μs, with 60V working stand-off voltage (VWM), 66.7–81.5V breakdown voltage (VBR), and 107V maximum clamping voltage (VC) at 4.9A peak pulse current - used for ESD and surge protection in automotive lighting and industrial control interfaces.
For engineers reviewing the SA60CA datasheet, SA60CA pinout, SA60CA application, or SA60CA equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification status, DO-15 thermal derating behavior, and compatibility with 12V/24V system-level transients per ISO 7637-2 and IEC 61000-4-5.
Technical Context
The SA60CA operates as a silicon avalanche diode configured for symmetrical bidirectional clamping, enabling protection of AC-coupled or floating signal lines without polarity sensitivity. Its VBR range (66.7–81.5V) and VC = 107V @ IPPM = 4.9A define its overvoltage limiting window under standardized 10/1000μs surge conditions.
It features low leakage (<1μA @ VWM), fast response (<5.0ns for bidirectional mode), and a temperature coefficient of 71 mV/°C for VBR - critical for stable clamping across –55°C to +175°C operating junction range. The device meets RoHS and halogen-free requirements per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse voltage before significant leakage; sets upper limit for normal operation in 24V/48V systems |
| VBR min/max | 66.7 / 81.5 V @ IT = 1 mA - defines guaranteed avalanche onset window; ensures predictable turn-on during transients |
| VC @ IPPM | 107 V @ 4.9 A - clamping voltage during 10/1000μs surge; determines protected circuit's maximum stress level |
| PPK | 500 W - peak pulse power rating; validates robustness against ISO 7637-2 Pulse 5a/b and IEC 61000-4-5 Level 4 surges |
| TJ max | +175 °C - maximum junction temperature; supports under-hood automotive placement with minimal heatsinking |
| IR @ VWM | <1 μA - reverse leakage at stand-off voltage; minimizes standby power loss in battery-backed systems |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case meeting UL 94V-0; cathode band not applicable (bidirectional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge current entry (positive half-cycle) | Conducts transient energy into ground path when voltage exceeds +VBR; symmetric with cathode |
| Cathode | Surge current entry (negative half-cycle) | Conducts transient energy into ground path when voltage exceeds –VBR; functionally identical to anode in CA variant |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or floating DC rails without polarity concerns |
| AEC-Q101 qualified (H suffix variant) | Validated for automotive under-hood use including temperature cycling, mechanical shock, and humidity testing per JESD22 |
| 5.0 ns response time | Ensures clamping activation before transient energy couples into sensitive IC inputs - critical for CAN, LIN, and sensor interfaces |
| DO-15 mechanical robustness | Supports manual soldering and wave soldering per J-STD-002; withstands 9.5 mm lead bending per JESD201 Class 2 whisker test |
| Halogen-free & RoHS compliant | Meets automotive OEM material declarations (IMDS, CAMDS) and end-of-life recycling requirements |
Applications
| Automotive Lighting Control | Industrial RS-485 Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA | Same VWM (60V), higher PPK (600W), SMB package (smaller footprint, lower thermal mass) | Preferred for space-constrained PCBs; requires tighter layout for thermal relief due to smaller pad area | Select SMBJ60CA when board area is limited and thermal management via copper pour is feasible |
| P6KE60CA | Same VWM (60V), same DO-15 package, lower PPK (600W), higher VC (103V @ 5.2A) | Legacy industrial design compatibility; slightly tighter clamping but lower surge margin than SA60CA | Select P6KE60CA for drop-in replacement in existing DO-15 footprints where 600W rating suffices |
Compared with SMBJ60CA and P6KE60CA, the SA60CA offers optimized thermal robustness in DO-15 for high-reliability automotive environments, with verified AEC-Q101 qualification (H-suffix variants) and halogen-free compliance - making it preferred for new designs targeting OEM Tier-1 supply chains.

FAQ
What is the breakdown voltage range for SA60CA?
The SA60CA has a minimum breakdown voltage (VBR) of 66.7 V and a maximum of 81.5 V at 1 mA test current, per the manufacturer's datasheet. This range ensures reliable avalanche conduction onset during overvoltage events while accommodating process variation. The SA60CA's specified VBR window directly supports its role as a 60V stand-off protector in 24V and 48V systems.
Is SA60CA unidirectional or bidirectional?
The SA60CA is a bidirectional TVS diode, indicated by the "CA" suffix per Taiwan Semiconductor's naming convention. It provides symmetrical clamping for both positive and negative transients, making it suitable for AC-coupled lines, differential interfaces, and floating DC rails. Unlike unidirectional SA60 variants, the SA60CA does not have a cathode band marking.
Does SA60CA meet AEC-Q101 qualification?
The base SA60CA part is not automatically AEC-Q101 qualified; only variants with the "H" suffix (e.g., SA60CAH) are explicitly qualified per AEC-Q101. The SA60CA datasheet states AEC-Q101 qualification is "available", meaning qualification applies to designated H-suffix versions. Designers requiring automotive-grade reliability must specify SA60CAH for under-hood or safety-critical applications.
What is the maximum clamping voltage of SA60CA under surge conditions?
The SA60CA has a maximum clamping voltage (VC) of 107 V at 4.9 A peak pulse current (IPPM), tested with the standard 10/1000μs waveform. This value defines the highest voltage imposed on protected circuitry during a worst-case surge event. The 107 V clamping level ensures compatibility with 75V-rated ICs and provides margin above the 60V working stand-off voltage.
What package type does SA60CA use?
The SA60CA uses the DO-204AC (DO-15) axial-leaded package, with dimensions conforming to JEDEC standards. It features pure tin-plated leads solderable per J-STD-002, UL 94V-0 mold compound, and a typical weight of 0.400 g. The DO-15 package provides proven thermal performance and mechanical reliability for through-hole and selective soldering assembly processes.
