Product details
Overview
SA6V0CA-T from Diodes Incorporated is a bi-directional 6.0 V transient voltage suppressor (TVS) diode in DO-15 package, rated for 500 W peak pulse power (10/1000 µs waveform), 48.5 A peak pulse current, and 10.3 V max clamping voltage at IPP. It provides bidirectional overvoltage protection for DC power rails and signal lines in industrial control interfaces and automotive body electronics.
For engineers reviewing the SA6V0CA-T datasheet, SA6V0CA-T pinout, SA6V0CA-T application, or SA6V0CA-T equivalent, key selection criteria include standoff voltage (6.0 V), clamping performance (10.3 V @ 48.5 A), unidirectional/bidirectional configuration, DO-15 mechanical compatibility, and RoHS-compliant tape-and-reel packaging (4K per reel).
Technical Context
This bi-directional TVS diode operates symmetrically across both polarities, with a reverse standoff voltage (VR) of 6.0 V, breakdown voltage range of 6.67–7.37 V at 10 mA test current, and temperature coefficient of 5.0 mV/°C. It uses glass-passivated silicon junction technology to achieve fast response time (<1.0 ns) and stable clamping under repetitive surge stress.
Designed for transient immunity per IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT), it delivers 500 W non-repetitive peak pulse power dissipation with derating above 25°C ambient and lead temperature limits up to 75°C for steady-state operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 500 W (10/1000 µs waveform; defines maximum single-event surge energy handling) |
| Reverse Standoff Voltage (VR) | 6.0 V (maximum continuous working voltage before clamping begins) |
| Breakdown Voltage (VBR) | 6.67–7.37 V @ 10 mA (guaranteed conduction onset threshold for bidirectional protection) |
| Max Clamping Voltage (VC) | 10.3 V @ 48.5 A IPP (voltage seen by protected circuit during full-rated surge) |
| Peak Pulse Current (IPP) | 48.5 A (maximum surge current supported at rated clamping voltage) |
| Operating Temperature | −65 °C to +175 °C (enables use in under-hood automotive and industrial environments) |
| Package | DO-15 (standard axial-leaded through-hole package; 9.5 mm lead length, board-mounted) |
Pinout & Package

|---|---|
Use Scenario: Protecting 5–12 V sensor input channels in programmable logic controllers from induced transients on factory floor wiring. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry point to shunt surge energy before reaching analog front-end or microcontroller GPIO. Use Value: Limits voltage excursion to ≤10.3 V during 48.5 A surge, preserving ADC reference integrity and preventing latch-up in 3.3 V/5 V logic domains. |
Use Scenario: Safeguarding LIN bus transceiver power supply pins and wake-up lines in door module ECUs exposed to load dump and jump-start events. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12 V rail, coordinated with upstream fuse and downstream LDO to meet ISO 7637-2 Pulse 1/2a/5a requirements. Use Value: Withstands 500 W pulses while maintaining <100 ns response, ensuring system reset-free operation during battery disconnection/reconnection. |
| USB Port ESD Protection | DC Power Input Filtering |
Use Scenario: Secondary-level ESD protection on USB 2.0 VBUS and D+/D− lines in embedded host devices where primary protection resides upstream. IC Role / Device Role / Timing Role: Fast-reacting bidirectional clamp absorbing ±15 kV contact discharge per IEC 61000-4-2, placed after common-mode choke. Use Value: Low clamping voltage (10.3 V) prevents damage to 5 V tolerant PHY transceivers while supporting full-speed signaling integrity. |
Use Scenario: Input-stage surge suppression on 5–24 V DC power supplies feeding industrial HMIs, motor drivers, and PoE-powered devices. IC Role / Device Role / Timing Role: First-line transient absorber mounted at bulk capacitor input, sized to handle repetitive surges without degradation. Use Value: 175 °C max junction temperature and −65 °C low-temp rating ensure operational continuity across extended environmental profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P6KE6V8CA | Same 6.8 V VR, but higher clamping (11.5 V @ 43.5 A) and lower peak power (600 W); DO-15 package, same RoHS tape-and-reel option | Higher clamping voltage reduces margin for 5 V systems; better suited for 12 V rails with higher tolerance | Select when higher surge margin is needed and 11.5 V clamping is acceptable for protected ICs |
| SMAJ6.0CA | Surface-mount SMA package; identical 6.0 V VR and 10.3 V VC, but lower 400 W peak power rating and 38.5 A IPP | Not compatible with through-hole assembly; requires PCB redesign and requalification for thermal performance | Choose only for space-constrained designs where DO-15 footprint is unavailable and 400 W rating suffices |
Compared with P6KE6V8CA and SMAJ6.0CA, SA6V0CA-T offers optimal balance of low clamping voltage (10.3 V), DO-15 through-hole reliability, and 500 W surge capacity-making it preferred for legacy industrial and automotive modules requiring proven mechanical robustness and ease of manual rework.

FAQ
What does the "CA" suffix indicate in SA6V0CA-T?
The "CA" suffix denotes a bi-directional TVS configuration, meaning the device clamps transients of either polarity symmetrically across its terminals. Unlike unidirectional variants (e.g., SA6V0A-T), it has no cathode band marking and functions identically regardless of orientation in-circuit.
Is SA6V0CA-T suitable for IEC 61000-4-5 surge testing?
Yes-SA6V0CA-T is rated for 500 W peak pulse power using the 10/1000 µs waveform defined in IEC 61000-4-5. Its 48.5 A IPP and 10.3 V clamping voltage enable compliance with Level 3 (1 kV line-to-earth) and Level 4 (2 kV) surge immunity when properly implemented with impedance-matched layout and grounding.
How does the DO-15 package affect thermal performance?
With 9.5 mm lead length and board-mounted mounting, the DO-15 package delivers 1.0 W steady-state power dissipation at TL = 75°C. Thermal resistance from junction-to-lead is approximately 100°C/W, making it suitable for intermittent surge duty but requiring derating per Figure 4 in the datasheet for sustained ambient temperatures above 25°C.
Why is SA6V0CA-T marked "Not Recommended for New Design"?
Diodes Incorporated issued this designation because newer platforms favor surface-mount TVS devices (e.g., SMAJ, SMCJ) with tighter parametric tolerances and improved surge consistency. SA6V0CA-T remains fully qualified and available for legacy production, repair, and applications where DO-15 mechanical robustness or through-hole assembly is mandatory.
