Product details
Overview
PTVS5V0S1UTR-Q from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in automotive power rails. It features 5.0 V reverse standoff voltage (VRWM), 6.4–7.0 V breakdown voltage (VBR), 9.2 V clamping voltage (VCL) at 43.5 A peak pulse current (IPPM), and operates up to 185 °C junction temperature.
For engineers reviewing the PTVS5V0S1UTR-Q datasheet, PTVS5V0S1UTR-Q pinout, PTVS5V0S1UTR-Q application, or PTVS5V0S1UTR-Q equivalent, key selection criteria include its AEC-Q101 qualification, 30 kV ESD rating (IEC 61000-4-2), 1 mm profile, and thermal resistance of 70 K/W (junction-to-ceramic PCB).
Technical Context
This TVS diode uses a silicon avalanche structure optimized for fast response (<1 ns) to transients per IEC 61643-321 (10/1000 µs waveform). Its unidirectional configuration provides low clamping voltage during positive surges while blocking reverse leakage (IRM ≤ 5 µA at VRWM).
Thermal design is enabled by dual thermal paths: Rth(j-a) = 70 K/W on ceramic PCB and Rth(j-sp) = 18 K/W to cathode solder point. The device maintains rated 400 W peak pulse power up to 125 °C ambient, with derating to ~220 W at 185 °C junction per Fig. 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/typ/max) | 6.4 / 6.7 / 7.0 V at 10 mA - Ensures reliable turn-on above normal rail voltage with margin |
| VCL @ IPPM | 9.2 V at 43.5 A - Limits downstream IC voltage stress during ISO 7637-2 Pulse 1/2a/5a events |
| PPPM | 400 W (10/1000 µs) - Withstands automotive load dump surges without degradation |
| Tj max | 185 °C - Supports under-hood placement near engines or power converters |
| ESD rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Eliminates need for additional ESD front-end protection |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive discrete semiconductors |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 5 V microcontroller supply lines in engine control units exposed to ISO 7637-2 load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between 5 V rail and chassis ground to clamp positive surges within 1 ns.

Use Scenario: Shielding communication interfaces (CAN, LIN) and gate drivers in EV on-board chargers operating near power stages. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional PTVS5V0S1UTR-Q guards 5 V logic rails against coupled switching noise. Use Value: Enables compact layout with 1 mm height, reducing board area vs. larger DO-214AC packages while meeting AEC-Q101. | Use Scenario: Protecting feedback and enable pins of isolated 5 V DC-DC converters in under-hood inverters. IC Role / Device Role / Timing Role: Clamping device placed directly at converter output pin to suppress ringing and cross-talk from adjacent high-dV/dt power switches. Use Value: Operates reliably at 185 °C junction temperature, eliminating thermal derating concerns in sealed converter housings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-Q | DO-214AC package (4.5 mm height), 400 W PPPM, VRWM = 5.0 V, VCL = 9.2 V, but Tj max = 150 °C | Larger footprint and lower temperature rating limit use in high-heat zones like powertrain ECUs | Select when board height >1 mm is acceptable and ambient temperature stays below 125 °C |
| TPSMA6L5.0 | SOD-123FL package (1.1 mm height), 400 W PPPM, VRWM = 5.0 V, VCL = 9.2 V, Tj max = 175 °C, AEC-Q101 qualified | Marginally lower max junction temperature (175 °C vs. 185 °C) and slightly higher Rth(j-a) (~80 K/W) | Choose if existing layout uses SOD-123FL footprint and 10 °C margin is acceptable for target application |
Compared with SMAJ5.0A-Q and TPSMA6L5.0, PTVS5V0S1UTR-Q delivers superior thermal resilience (185 °C), tighter height control (1.0 mm), and identical clamping performance-making it optimal for next-generation automotive modules where space and under-hood temperature are critical constraints.

FAQ
What is the maximum clamping voltage of PTVS5V0S1UTR-Q under standard test conditions?
The clamping voltage (VCL) is 9.2 V at 43.5 A peak pulse current (IPPM), measured per IEC 61643-321 (10/1000 µs waveform) at Tj = 25 °C. This value remains stable across temperature, varying less than ±5 % from -55 °C to +150 °C, ensuring predictable protection behavior in automotive thermal profiles.
Does PTVS5V0S1UTR-Q support bidirectional transient suppression?
No, PTVS5V0S1UTR-Q is a unidirectional TVS diode. It conducts only during positive voltage transients on the cathode relative to anode. For bidirectional protection (e.g., data lines), two devices in series opposition or a dedicated bidirectional TVS such as PTVS5V0S1UTR-Q's counterpart in the same series would be required.
How does the SOD123W package improve thermal performance compared to standard SOD-123?
The SOD123W (CFP3) package features an extended cathode pad and optimized internal leadframe geometry, reducing thermal resistance to 18 K/W (junction-to-solder point) versus ~25 K/W in standard SOD-123. This enables higher sustained power dissipation and improved reliability in high-temperature PCB layouts, especially on ceramic substrates.
Can PTVS5V0S1UTR-Q replace older TVS diodes like SMAJ5.0A in existing designs?
Yes, with layout adaptation: both share identical VRWM (5.0 V) and VCL (9.2 V), but PTVS5V0S1UTR-Q uses SOD123W (2.6 × 1.7 × 1.0 mm) versus SMAJ5.0A's DO-214AC (4.5 × 2.7 × 2.2 mm). The smaller footprint and 1 mm height require revised land patterns, yet deliver better thermal capability and AEC-Q101 alignment for new automotive releases.
