Product details
Overview
SA5V0A-T from Diodes Incorporated is a unidirectional 500W transient voltage suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection at DC power inputs and signal lines. It features a 5.0 V reverse standoff voltage, 6.4–7.0 V breakdown range at 10 mA, 9.2 V max clamping voltage at 54.3 A peak pulse current, and operates from –65°C to +175°C.
For engineers reviewing the SA5V0A-T datasheet, SA5V0A-T pinout, SA5V0A-T application, or SA5V0A-T equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal derating above 25°C ambient, unidirectional polarity marking, and compatibility with lead-free reflow profiles per J-STD-020C Level 1.
Technical Context
This TVS diode uses glass-passivated silicon junction technology to achieve fast response time (<1.0 ps) and stable clamping during transient events such as ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and lightning-induced surges (10/1000 µs waveform). Its unidirectional configuration provides low-leakage protection on positive-rail circuits without reverse conduction path.
Rated for 500 W non-repetitive peak pulse power at TL = 75°C with 9.5 mm lead length, it delivers 54.3 A peak pulse current at 9.2 V clamping while maintaining <600 µA reverse leakage at 5.0 V standoff - critical for low-power sensor and microcontroller I/O line protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 500 W @ 10/1000 µs waveform - sustains single high-energy transients without failure |
| Reverse Standoff Voltage (VR) | 5.0 V - maximum continuous DC voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 6.4–7.0 V @ 10 mA - precise avalanche initiation threshold for predictable clamping onset |
| Clamping Voltage (VC) | 9.2 V @ IPP = 54.3 A - limits downstream voltage stress during worst-case surge |
| Peak Pulse Current (IPP) | 54.3 A - maximum surge current handled at rated clamping voltage |
| Operating Temperature | –65°C to +175°C - supports automotive under-hood and industrial control environments |
| Package | DO-15 - axial-leaded, board-mounted format with 9.5 mm lead length for 1.0 W steady-state dissipation |
Pinout & Package
DO-15 package: axial-leaded, molded plastic case (UL 94V-0), cathode band marking for unidirectional polarity, 0.4 g typical weight. Leads are matte tin-plated, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; defines unidirectional conduction direction |
| Cathode | High-side connection point | Connected to protected line (e.g., +5V rail); marked by band; conducts during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| 500 W peak pulse power rating | Provides robust protection against IEC 61000-4-5 Level 4 (4 kV) surges on 5 V supply rails |
| Fast response time | Sub-nanosecond turn-on ensures clamping occurs before sensitive ICs experience overstress |
| RoHS-compliant matte tin plating | Supports lead-free reflow assembly without whisker risk or solderability degradation |
| –65°C to +175°C operating range | Validates use in extended-temperature automotive ECUs and industrial motor drives |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Module |
|---|---|
Use Scenario: Protecting 5 V CAN transceiver power pins against load dump and jump-start transients. IC Role / Device Role / Timing Role: Primary clamping device placed between fuse and LDO input to limit voltage excursion to ≤9.2 V. Use Value: Prevents LDO overvoltage failure and maintains CAN communication integrity during 12 V system surges. | Use Scenario: Safeguarding 5 V optocoupler input circuitry on isolated digital input cards exposed to field wiring noise. IC Role / Device Role / Timing Role: First-line transient suppressor shunting induced surges before they reach the opto-IC's internal LED driver. Use Value: Extends optocoupler lifetime and eliminates false triggering caused by >1 kV EFT bursts. |
| USB-C Power Delivery Adapter | Smart Energy Meter MCU Power Rail |
Use Scenario: Clamping 5 V VBUS line against hot-plug and cable discharge events in USB-C PD sink applications. IC Role / Device Role / Timing Role: Unidirectional TVS placed directly at connector to absorb sub-100 ns ESD pulses before reaching buck controller. Use Value: Meets IEC 61000-4-2 ±15 kV air/±8 kV contact discharge requirements without adding series impedance. | Use Scenario: Securing 5 V supply to metrology SoC and RTC in utility-grade smart meters subject to grid switching transients. IC Role / Device Role / Timing Role: Low-leakage (≤600 µA @ 5 V) clamping element ensuring no battery drain during standby mode. Use Value: Maintains 10-year meter battery life while surviving repeated 6 kV lightning-induced surges per IEC 61000-4-5. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P6KE6V8A | 600 W peak power, 6.8 V standoff, 10.5 V clamping @ 56.2 A, DO-15 package | Higher standoff and clamping voltage; better suited for 6–7 V systems with tighter margin | Select when protecting 6.3 V LDO outputs where 5.0 V standoff would cause premature conduction |
| SMAJ5.0A | 400 W peak power, same 5.0 V standoff, 9.2 V clamping @ 43.5 A, SMA package | Surface-mount format; lower thermal mass; requires PCB copper area for heat dissipation | Choose for space-constrained designs needing automated assembly, accepting reduced surge handling vs. axial DO-15 |
Compared with SA5V0A-T, P6KE6V8A offers higher surge capacity but less precise 5 V rail matching, while SMAJ5.0A trades peak power for SMT manufacturability - both require layout and thermal reassessment for drop-in replacement.

FAQ
Is SA5V0A-T RoHS compliant and lead-free?
Yes. SA5V0A-T features matte tin-plated leads and conforms to RoHS Directive 2011/65/EU, including exemptions for high-temperature solder and glass under Annexes 5 and 7. It meets J-STD-020C Level 1 moisture sensitivity and supports lead-free reflow profiles up to 260°C peak.
What is the meaning of the "-T" suffix in SA5V0A-T?
The "-T" suffix indicates tape-and-reel packaging: 4,000 units per 13-inch reel, optimized for automated SMT placement. This differs from "-B" (bulk packaging) and does not affect electrical specifications or thermal performance.
Can SA5V0A-T be used in bidirectional configurations?
No. SA5V0A-T is unidirectional only, indicated by the "A" suffix (not "CA"). For bidirectional operation at 5 V, the correct part is SA5V0CA-T, which has symmetrical clamping in both polarities and double the IR limit per Note 2 in the datasheet.
Why is SA5V0A-T marked "Not Recommended for New Design"?
Diodes Incorporated issued this advisory due to obsolescence planning and newer alternatives (e.g., P6KE6V8A) offering improved surge margin and broader qualification. SA5V0A-T remains fully functional and supported for legacy production, with full parametric compliance and no known reliability issues.
