Product details
Overview
SA60C from Taiwan Semiconductor is a unidirectional 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 - designed for automotive-grade ESD and load-dump protection in power supply rails and signal lines.
For engineers reviewing the SA60C datasheet, SA60C pinout, SA60C application, or SA60C equivalent, this page delivers verified electrical parameters, polarity-aware package details, AEC-Q101 qualification status, clamping performance under standardized surge waveforms, and direct alternatives for circuit-level ESD hardening and inductive switching transient suppression.
Technical Context
The SA60C operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its VBR range (66.7–81.5V @ 1mA), clamping transients to ≤107V at 4.9A. Its low leakage (<1μA @ 60V) ensures minimal standby power loss in always-on systems.
Designed per ANSI/IEEE C62.35, it sustains 500W non-repetitive surges (10/1000μs), exhibits <1.0ps response time from 0V to VBR, and maintains stable operation across –55°C to +175°C junction temperature range - supporting under-hood automotive and industrial control applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 66.7 / 81.5 V @ 1 mA - guaranteed avalanche initiation window for predictable turn-on |
| VC @ IPPM | 107 V @ 4.9 A - clamped voltage during 10/1000μs surge, defining worst-case stress on downstream ICs |
| PPK | 500 W - peak pulse power handling capability per single 10/1000μs transient |
| IR @ VWM | <1 μA - negligible leakage current at rated stand-off voltage, critical for battery-powered circuits |
| TJ max | +175 °C - extended thermal rating enabling placement near heat sources in engine control units |
Pinout & Package
SA60C uses the DO-204AC (DO-15) axial-leaded package with cathode band marking for unidirectional polarity. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; defines current flow direction during clamping |
| Cathode | Protected line input | Connected to the line being protected (e.g., 12V rail); conducts surge current to ground when V > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, mechanical shock, and humidity testing per stress test requirements |
| Fast response time | <1.0 ps from 0 V to VBR - enables suppression of nanosecond-scale ESD events before IC damage occurs |
| Low clamping ratio | VC/VBR ≈ 1.33 - tight voltage margin between breakdown and clamping reduces overvoltage stress on protected devices |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS directives - supports environmentally compliant manufacturing and end-of-life recycling |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A | Same DO-214AC package; slightly higher VBR (66.7–73.7V), lower VC (96.8V @ 5.4A), same 500W rating | Bidirectional variant available; SMAJ series lacks AEC-Q101 qualification by default | Select SMAJ60A only if AEC-Q101 is not required and tighter clamping voltage is prioritized |
| P6KE60CA | DO-204AC package; bidirectional configuration; VBR 66.7–73.7V; VC 98.0V @ 5.1A; 600W rating | Not AEC-Q101 qualified; higher capacitance may affect high-speed signal lines | Choose P6KE60CA for cost-sensitive industrial designs where bidirectional protection and higher peak power are needed |
Compared with SMAJ60A and P6KE60CA, SA60C provides AEC-Q101 validation, unidirectional polarity for optimized power rail placement, and a clamping ratio (1.33) that balances protection margin and component stress - making it preferred for automotive ECU and safety-critical embedded systems.

FAQ
What is the polarity configuration of SA60C?
SA60C is a unidirectional TVS diode, with cathode marked by a band on the DO-204AC (DO-15) package body. It conducts only when the cathode is at a higher potential than the anode - making it suitable for protecting positive power rails against overvoltage transients. This polarity must be observed during PCB layout to ensure proper clamping function.
Is SA60C AEC-Q101 qualified?
Yes, SA60C is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's official documentation and ordering code suffix "H" (e.g., SA60CH). This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock, validating its suitability for automotive under-hood and chassis applications.
What is the maximum clamping voltage of SA60C and at what current is it specified?
The maximum clamping voltage (VC) of SA60C is 107 V, measured at a peak pulse current (IPPM) of 4.9 A under the standard 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
How does SA60C compare to SA60A in terms of breakdown voltage and clamping performance?
SA60C has a VBR range of 66.7–81.5 V and clamps at 107 V @ 4.9 A, whereas SA60A specifies VBR of 66.7–73.7 V and clamps at 96.8 V @ 5.4 A. SA60A offers tighter VBR tolerance and lower VC but lacks AEC-Q101 qualification unless ordered with "H" suffix - SA60C trades slightly higher clamping for automotive-grade reliability.
Can SA60C be used in bidirectional configurations?
No, SA60C is strictly unidirectional and must not be used for bidirectional protection. For symmetrical transient suppression (e.g., data lines), select the bidirectional SA60CA variant - which features identical VBR and VC ratings in both directions and is explicitly designated for bipolar applications in Taiwan Semiconductor's SA Series documentation.
