Product details
Overview
SA5.0C from Taiwan Semiconductor is a unidirectional 500W transient voltage suppressor (TVS) diode with 5.0V working stand-off voltage, 6.4–7.3V breakdown voltage at 10mA, and 54.0V clamping voltage at 600A peak pulse current. It features sub-1ps response time, <1μA reverse leakage above 10V, and DO-204AC (DO-15) package - designed for automotive ESD and inductive load surge protection in power supply inputs.
For engineers reviewing the SA5.0C datasheet, SA5.0C pinout, SA5.0C application, or SA5.0C equivalent, key selection criteria include clamping performance under 10/1000μs surges, unidirectional polarity marking, AEC-Q101 qualification status, thermal derating above 25°C, and compatibility with lead-free reflow profiles per J-STD-002.
Technical Context
The SA5.0C operates as a silicon avalanche diode optimized for fast transient suppression in DC power rails. Its unidirectional configuration provides low-clamp forward conduction during positive surges while blocking reverse voltage up to 5.0V under normal operation.
It delivers 500W peak pulse power at TA = 25°C with 10/1000μs waveform compliance, derates linearly above 25°C per Fig.2, and sustains 70A non-repetitive forward surge (8.3ms half-sine) - critical for relay coil or solenoid switching transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse voltage before significant leakage; sets upper limit for protected circuit operating voltage |
| VBR @ IT=10mA | 6.4–7.3 V - Breakdown onset range; ensures reliable triggering before downstream IC damage thresholds |
| VC @ IPPM=600A | 54.0 V - Clamped voltage during full-rated surge; defines worst-case stress on downstream components |
| PPK | 500 W - Peak surge energy handling per 10/1000μs waveform; validates immunity to IEC 61000-4-5 Level 4 |
| IR @ VWM | <1 μA - Ultra-low leakage at stand-off voltage; avoids parasitic loading in high-impedance sensor or bias networks |
| TJ max | +175 °C - Extended junction temperature rating enables under-hood automotive deployment without derating |
| Package | DO-204AC (DO-15) - Industry-standard axial-leaded package with 0.400g mass; compatible with legacy through-hole assembly |
Pinout & Package

Applications
| Automotive Power Input Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 5V microcontroller power rail exposed to load-dump and jump-start transients in vehicle body control modules. IC Role / Device Role / Timing Role: Unidirectional TVS placed between fused battery feed and LDO input to clamp surges before regulator failure.

Use Scenario: RS-485 transceiver VCC line in factory automation PLC I/O modules subject to inductive switching noise. IC Role / Device Role / Timing Role: Standoff protector on 5V supply rail adjacent to isolated data interface to absorb coupled transients from nearby contactors. Use Value: Sub-1ps response captures fast edge-induced spikes before they couple into transceiver bias networks or reference regulators. |
| LED Driver Surge Suppression | USB Port ESD Protection |
Use Scenario: Constant-current LED driver IC powered from 5V buck converter in automotive headlamp assemblies. IC Role / Device Role / Timing Role: Primary surge shunt on driver IC VDD pin to prevent latch-up during PWM dimming-induced inductive kickback. Use Value: 70A IFSM rating withstands repetitive 8.3ms coil-switching surges without degradation, ensuring 15-year lamp life. |

IC Role / Device Role / Timing Role: First-stage clamping device upstream of USB switch IC to divert >8kV contact discharge energy. Use Value: 1μA leakage at 5V avoids false disconnect detection by USB PHY while maintaining low standby power in always-on systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Unidirectional, 600W PPK, 6.4–7.0V VBR, DO-214AC (SMA) package | Surface-mount footprint requires PCB redesign; higher surge rating but larger clamping voltage (64.0V) | Preferred for new SMT designs requiring higher power margin and automated assembly |
| P6KE5.0A | Unidirectional, 600W PPK, 6.4–7.0V VBR, DO-204AL (DO-41) package | Same axial form factor but lower thermal mass; 150°C TJ max vs. SA5.0C's 175°C | Acceptable for non-automotive industrial use where AEC-Q101 and extended temperature are not required |
Compared with SMAJ5.0A and P6KE5.0A, the SA5.0C offers AEC-Q101 qualification and +175°C junction rating for under-hood deployment, while its DO-204AC package maintains legacy through-hole compatibility without layout change - unlike SMAJ5.0A - and exceeds P6KE5.0A's thermal capability for sustained surge duty cycles.

FAQ
What is the maximum clamping voltage of the SA5.0C under rated surge conditions?
The SA5.0C exhibits a maximum clamping voltage (VC) of 54.0 V when subjected to its rated 600 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured at TA = 25°C and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The SA5.0C datasheet specifies this parameter in the "Maximum clamping voltage VC@IPPM" row for part number SA5.0.
Is the SA5.0C suitable for bidirectional transient protection?
No, the SA5.0C is a unidirectional TVS diode, indicated by the "C" suffix and confirmed by its single cathode band marking and asymmetric electrical characteristics. For bidirectional protection, Taiwan Semiconductor offers the SA5.0CA variant. Using SA5.0C in reverse-biased configurations risks premature breakdown or failure due to lack of symmetric reverse standoff capability.
Does the SA5.0C meet AEC-Q101 qualification standards?
Yes, the SA5.0C is explicitly AEC-Q101 qualified, as stated in the "FEATURES" section of the official SA Series datasheet (Version L2105). This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD robustness - confirming suitability for automotive electronic control units and powertrain modules.
What is the thermal derating behavior of the SA5.0C above 25°C ambient?
The SA5.0C's peak pulse power (PPK) derates linearly above TA = 25°C, following the curve in Figure 2 of the datasheet. At 75°C ambient, its PPK drops to approximately 350W, and at 125°C it falls to ~175W. This derating must be applied when calculating surge margin in high-temperature environments such as engine compartments or enclosed industrial enclosures.
Can the SA5.0C be used in place of the SA5.0A variant?
No - the SA5.0C and SA5.0A differ in breakdown voltage range: SA5.0C is 6.4–7.3 V, while SA5.0A is 6.4–7.0 V. Though both share 5.0 V VWM and 54.0/57.0 V clamping, the tighter VBR tolerance of SA5.0A may be required in precision voltage-margin applications. Substitution requires validation against system-level surge test margins and VBR distribution effects.
