Product details
Overview
SA6V5CA-T from Diodes Incorporated is a bi-directional 500W transient voltage suppressor (TVS) diode in DO-15 package, designed for surge protection on AC signal lines and bidirectional data/power interfaces. It features a 6.5V reverse standoff voltage (VR), 7.22–7.98V breakdown voltage (VBR) at 10mA, 11.2V clamping voltage (VC) at 44.7A peak pulse current (IPP), and operates from –65°C to +175°C.
For engineers reviewing the SA6V5CA-T datasheet, SA6V5CA-T pinout, SA6V5CA-T application, or SA6V5CA-T equivalent, key selection criteria include bidirectional clamping capability, 500W 10/1000µs pulse rating, DO-15 mechanical compatibility, temperature-stable VBR (5.0 mV/°C), and RoHS-compliant matte tin plating.
Technical Context
This TVS diode uses glass-passivated silicon junction technology to achieve fast response time (<1.0 ps) and low clamping ratio (VC/VBR ≈ 1.55). Its bi-directional configuration enables symmetrical surge suppression on AC-coupled or floating circuits without polarity constraints.
The device complies with IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) immunity standards when properly mounted with short trace lengths. Thermal derating begins above TA = 25°C, with full power (500W) limited to TL ≤ 75°C per 9.5mm lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 500 W (10/1000 µs waveform, non-repetitive) |
| Reverse Standoff Voltage (VR) | 6.5 V (maximum working voltage before clamping onset) |
| Breakdown Voltage (VBR) | 7.22–7.98 V @ 10 mA (guaranteed conduction threshold) |
| Clamping Voltage (VC) | 11.2 V @ 44.7 A IPP (voltage seen by protected circuit during surge) |
| Peak Pulse Current (IPP) | 44.7 A (maximum surge current survivable at rated VC) |
| Operating Temperature | –65°C to +175°C (enables under-hood, industrial, and high-reliability use) |

Applications
| Industrial AC Motor Drives | Telecom Line Interface |
|---|---|
Use Scenario: Protection of gate driver inputs and feedback sensing nodes against switching transients in variable-frequency drives. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across isolated signal paths to limit common-mode surges induced by IGBT commutation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P6KE6V8CA | Same DO-15 package, 600W rating, 6.8V VR, 10.5V VC @ 57.1A IPP | Higher power margin but larger clamping voltage tolerance (±5%) vs. SA6V5CA-T's tighter VBR spread | Select when higher surge margin is required and PCB layout allows slightly higher clamped voltage |
| SMAJ6.8CA | SMA package (surface-mount), 400W rating, 6.8V VR, 11.2V VC @ 35.7A IPP | Smaller footprint and automated assembly compatible, but lower peak power and thermal derating | Select for space-constrained designs where 400W surge immunity suffices and reflow compatibility is mandatory |
Compared with P6KE6V8CA and SMAJ6.8CA, SA6V5CA-T offers tighter VBR tolerance (±5.5% vs. ±10%), identical clamping voltage (11.2V), and optimal thermal performance in through-hole configurations - making it preferred for legacy industrial and telecom systems requiring proven reliability and manual repairability.

FAQ
Is SA6V5CA-T suitable for IEC 61000-4-5 Level 4 compliance?
Yes. With its 500W 10/1000µs rating and 11.2V clamping voltage at 44.7A, SA6V5CA-T meets IEC 61000-4-5 Level 4 (4kV line-to-line, 2Ω source) when implemented with proper PCB layout - including minimized loop area, direct grounding to chassis, and series impedance matching.
What is the difference between SA6V5CA-T and SA6V5A-T?
SA6V5CA-T is bi-directional (suffix "CA"), providing symmetrical clamping for AC or floating circuits; SA6V5A-T is unidirectional (suffix "A") with cathode band marking and intended for DC rail protection. Their VBR, VC, and power ratings are identical, but polarity handling differs fundamentally.
Can SA6V5CA-T be used in surface-mount designs?
No - SA6V5CA-T uses the axial DO-15 through-hole package. For surface-mount equivalents, consider SMAJ6.8CA (SMA) or SMCJ6.8CA (SMC); both offer bi-directional clamping but differ in thermal dissipation, peak power, and mounting method.
Why is SA6V5CA-T marked "Not Recommended for New Design"?
Diodes Incorporated issued this advisory due to newer platforms (e.g., P6KE series) offering improved surge margin and tighter parametric consistency. However, SA6V5CA-T remains fully qualified, in active production, and supported for legacy design refreshes, repair, and long-life industrial deployments.
