Product details
Overview
PTVS7V0S1UTR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in power rails. It features VRWM = 7.0 V, VBR(min) = 7.78 V at 10 mA, VCL = 12.0 V at IPPM = 33.3 A (10/1000 µs), and operates up to Tj = 185 °C - ideal for industrial power supply clamping.
For engineers reviewing the PTVS7V0S1UTR,115 datasheet, PTVS7V0S1UTR,115 pinout, PTVS7V0S1UTR,115 application, or PTVS7V0S1UTR,115 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, thermal resistance under PCB layout constraints, peak pulse current handling at elevated junction temperature, and cathode-anode polarity marking for correct board placement.
Technical Context
This unidirectional TVS diode uses an avalanche breakdown mechanism to clamp transients above its reverse standoff voltage (VRWM = 7.0 V). Its VBR range (7.78–8.60 V at 10 mA) ensures reliable triggering while maintaining low leakage (IRM ≤ 3 µA at VRWM).
It complies with IEC 61643-321 for 10/1000 µs waveform testing and delivers 400 W peak pulse power at 25 °C, derating to ~280 W at Tj = 150 °C per Fig. 2. The SOD123W package enables surface-mount integration with 1 mm height and thermal resistance Rth(j-sp) = 18 K/W to solder point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 7.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min) | 7.78 V at 10 mA - guaranteed avalanche initiation threshold for reliable overvoltage response |
| VCL | 12.0 V at IPPM = 33.3 A - clamped voltage during 10/1000 µs surge, defining protected circuit stress level |
| PPPM | 400 W at 25 °C - peak transient energy absorption capability per IEC 61643-321 |
| IRM | ≤ 3 µA at VRWM - ultra-low leakage preserves system standby power integrity |
| Tj max | 185 °C - enables operation in under-hood, motor drive, or high-ambient industrial environments |
| Rth(j-sp) | 18 K/W - low thermal resistance to cathode solder point supports sustained surge dissipation on standard PCBs |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +VOUT); polarity-sensitive - reverse connection disables clamping |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance path to GND during transient events |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rating up to 185 °C enables use in engine control units, industrial inverters, and sealed enclosures without derating |
| Low-profile SMD package | 1 mm height allows integration into space-constrained power modules and dense DC/DC converter layouts |
| Controlled clamping performance | VCL = 12.0 V at 33.3 A ensures predictable voltage limiting for 5 V or 3.3 V rail protection with safety margin |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) and >8 kV HBM support system-level ESD immunity without additional front-end protection |
| Stable leakage across temperature | IRM ≤ 3 µA at VRWM and Tj = 150 °C maintains low quiescent current in always-on power management circuits |
Applications
| Industrial Power Supply Protection | Motor Drive DC Bus Clamping |
|---|---|
Use Scenario: Protecting 12 V input rails in programmable logic controllers (PLCs) against load dump and inductive switching spikes. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND to clamp surges within 1 ns response time. Use Value: VCL = 12.0 V limits stress on downstream DC/DC converters and microcontrollers, preventing latch-up or damage during 400 W transients. |
Use Scenario: Suppressing commutation spikes on 24 V DC bus in brushless motor drives operating at ambient temperatures up to 105 °C. IC Role / Device Role / Timing Role: Fast-acting clamping device absorbing flyback energy from MOSFET switching transitions. Use Value: 185 °C Tj rating ensures stable clamping performance without thermal runaway, even during extended high-load operation. |
| Automated Test Equipment (ATE) Power Rails | High-Temperature Sensor Interface Protection |
Use Scenario: Safeguarding precision analog front-ends in ATE systems exposed to relay bounce and relay coil back-EMF. IC Role / Device Role / Timing Role: Low-leakage TVS on ±15 V analog supply lines to prevent transient-induced measurement errors. Use Value: IRM ≤ 3 µA avoids loading sensitive op-amp bias networks, preserving accuracy in µV-level signal paths. |
Use Scenario: Protecting RTD or thermocouple signal conditioning circuits mounted near exhaust manifolds or furnace controls. IC Role / Device Role / Timing Role: Standoff-rated clamping element on sensor excitation lines subject to thermal cycling and ESD. Use Value: Stable VBR and VRWM across -55 °C to 150 °C ambient ensures consistent protection behavior without parameter drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | VRWM = 7.0 V, VCL = 12.0 V, PPPM = 400 W, but Tj max = 150 °C and Rth(j-a) = 95 K/W (vs. 70 K/W typical for PTVS7V0S1UTR) | Not rated for continuous operation above 150 °C; unsuitable for under-hood or sealed high-temp enclosures | Select when ambient temperature remains below 105 °C and cost sensitivity outweighs thermal margin needs |
| 1.5SMC7.0A | Same VRWM/VCL, but DO-214AB package (4.5 mm height), PPPM = 1500 W, Tj max = 175 °C, IRM = 1000 µA | Higher leakage degrades low-power sensor bias networks; larger footprint incompatible with dense SMT layouts | Choose only when surge energy exceeds 400 W and board space permits larger package |
Compared with SMAJ7.0A and 1.5SMC7.0A, PTVS7V0S1UTR,115 uniquely balances 185 °C junction rating, sub-1 mm profile, and <3 µA leakage - making it optimal for miniaturized, high-reliability industrial power protection where thermal headroom and layout density are critical.

FAQ
What is the maximum clamping voltage of PTVS7V0S1UTR,115 under standard test conditions?
The clamping voltage VCL is 12.0 V at a peak pulse current IPPM of 33.3 A using the 10/1000 µs waveform per IEC 61643-321. This value is measured at Tj = 25 °C and defines the upper voltage limit imposed on the protected line during surge events.
Does PTVS7V0S1UTR,115 support bidirectional transient suppression?
No - PTVS7V0S1UTR,115 is a unidirectional TVS diode. It conducts only when the cathode is positive relative to the anode, making it suitable for DC rail protection. Bidirectional variants (e.g., PTVS7V0S1UTR-B) are separate part numbers with different internal construction and marking.
How does the 185 °C junction temperature rating impact PCB layout?
The 185 °C Tj rating allows sustained operation under high ambient or self-heating conditions, but effective heat transfer requires optimized copper pour on the cathode pad. The datasheet specifies Rth(j-sp) = 18 K/W to solder point - achieved using ≥1 cm² tin-plated copper on FR4, per Table 6 footnote [4].
Is the marking code 'C6' on the device body sufficient for full identification?
Yes - per Table 4, 'C6' is the official marking for PTVS7V0S1UTR. The bar adjacent to pin 1 identifies the cathode. No additional date or lot codes are required for functional identification; full traceability is maintained via reel label and shipping documentation.
