Product details
Overview
SA5V0A-T-F from Diodes Incorporated is a unidirectional 500W transient voltage suppressor (TVS) diode in DO-15 package, rated for 5.0V reverse standoff voltage, 6.4–7.0V breakdown at 10mA, and clamping voltage of 9.2V at 54.3A peak pulse current. It provides fast-response overvoltage protection for DC power rails and I/O lines in industrial control systems.
For engineers reviewing the SA5V0A-T-F datasheet, SA5V0A-T-F pinout, SA5V0A-T-F application, or SA5V0A-T-F equivalent, key selection criteria include clamping voltage margin versus protected IC VDD, peak pulse current handling under 10/1000µs waveform, thermal derating above 25°C ambient, and compatibility with lead-free reflow profiles per J-STD-020C Level 1.
Technical Context
This TVS diode operates as a clamping device that transitions from high-impedance standby to low-impedance conduction when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR and low leakage (<600µA @ 5V) across -65°C to +175°C operating range.
Designed for single-pulse suppression per REA 10×1000µs waveform, it delivers 500W peak pulse power with <1.0ns response time and exhibits ±5.0mV/°C temperature coefficient on VBR, enabling predictable performance in thermally varying environments.
Key Specifications

Applications
| Industrial PLC I/O Protection | Automotive Body Control Module |
|---|---|
Use Scenario: Protecting 5V sensor inputs against load dump and inductive switching transients in programmable logic controllers. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between input pin and ground, responding within nanoseconds to suppress >100V spikes. Use Value: Maintains signal integrity below 9.2V clamping level while surviving repeated 54.3A pulses per IEC 61000-4-5. | Use Scenario: Safeguarding LIN bus transceiver power supply pins against battery reverse polarity and jump-start surges. IC Role / Device Role / Timing Role: Standoff-rated TVS on 5V VCC rail, conducting only during overvoltage events to shunt energy to chassis ground. Use Value: Prevents latch-up or permanent damage to transceivers by limiting rail voltage excursion to ≤9.2V during 100V/50ms load dump. |
| Medical Diagnostic Equipment | Point-of-Sale Terminal Power Input |
Use Scenario: Securing isolated 5V auxiliary supplies feeding analog front-end ADCs in portable ultrasound units. IC Role / Device Role / Timing Role: Primary overvoltage clamp on secondary-side DC/DC output, coordinated with upstream fuse and common-mode choke. Use Value: Enables EN 60601-1 compliance by limiting transient propagation into sensitive analog measurement paths. | Use Scenario: Protecting 5V USB-powered peripherals from hot-plug induced voltage spikes and ESD events. IC Role / Device Role / Timing Role: Low-capacitance TVS on VBUS line, placed immediately after connector to minimize trace inductance impact. Use Value: Clamps 8kV contact ESD per IEC 61000-4-2 to <9.2V without degrading signal rise time due to DO-15 parasitic capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P6KE6V8A | Same DO-15 package; 6.8V standoff; 10.5V clamping @ 43.8A; 600W rating | Higher VR and VC - better suited for 6–7V rails where 5V margin is insufficient | Select when protecting circuits with nominal 6.3V or higher supply rails requiring tighter clamping margin |
| SMAJ5.0A | SMA package (surface-mount); same 5.0V standoff; 9.2V clamping @ 43.5A; 400W rating | Smaller footprint and lower profile - suitable for space-constrained PCBs but with reduced pulse handling | Choose for automated assembly and compact designs where 54.3A peak current requirement is relaxed |
Compared with SA5V0A-T-F, P6KE6V8A offers higher surge capacity and elevated clamping threshold for 6–7V systems, while SMAJ5.0A trades pulse robustness for board space savings and SMT compatibility-neither matches the original's 500W/54.3A capability in through-hole DO-15 form.

FAQ
Is SA5V0A-T-F suitable for bidirectional signal line protection?
No. SA5V0A-T-F is unidirectional, with cathode marked and designed for clamping positive transients to ground. For bidirectional protection (e.g., AC lines or data buses), use SA5V0CA-T-F or other CA-suffix variants explicitly rated for symmetrical clamping.
What is the maximum allowable PCB trace length between SA5V0A-T-F and protected IC?
Trace inductance directly impacts clamping effectiveness. For sub-9.2V protection, keep total anode-to-ground and cathode-to-line loop inductance below 10 nH - typically achieved with ≤5 mm trace length and direct ground plane connection beneath the DO-15 body.
Does SA5V0A-T-F meet IEC 61000-4-5 Level 4 surge requirements?
Yes, when used in conjunction with appropriate layout practices (short traces, low-inductance grounding, and series impedance), SA5V0A-T-F can support IEC 61000-4-5 Level 4 (4kV line-earth, 2kV line-line) due to its 500W/54.3A rating and sub-1ns response time.
Why is SA5V0A-T-F marked "Not Recommended for New Design"?
Diodes Incorporated issued this advisory because newer TVS families (e.g., P6KE, SMAJ) offer improved surge robustness, tighter parameter distributions, and broader qualification coverage. SA5V0A-T-F remains fully functional and supported for existing designs and legacy replacements.
