Product details
Overview
PTVS5V0S1UTR,115 from Nexperia is a unidirectional 400 W transient voltage suppressor (TVS) diode in SOD123W (CFP3) package, designed for high-temperature overvoltage protection in 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, and operates up to 185 °C junction temperature.
For engineers reviewing the PTVS5V0S1UTR,115 datasheet, PTVS5V0S1UTR,115 pinout, PTVS5V0S1UTR,115 application, or PTVS5V0S1UTR,115 equivalent, this device is selected for robust ESD and surge immunity in industrial power management, automotive body electronics, and high-reliability DC supply lines where thermal stability and low-profile mounting are critical.
Technical Context
This unidirectional TVS diode uses an avalanche breakdown mechanism to clamp transients above its VRWM of 5.0 V. Its VBR range (6.4–7.0 V at 10 mA) ensures precise triggering with minimal overshoot, while the 9.2 V clamping voltage at IPPM = 43.5 A limits downstream voltage stress under IEC 61643-321 10/1000 µs surges.
Thermal design is enabled by Rth(j-sp) = 18 K/W to solder point and Tj max = 185 °C, supporting operation in ambient temperatures up to +185 °C. The cathode-marked SOD123W package provides 1 mm profile height and 2.6 × 1.7 mm footprint for space-constrained PCB layouts.
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, repeatable avalanche turn-on with tight tolerance |
| VCL | 9.2 V at IPPM = 43.5 A - Limits protected circuit voltage during 400 W transient events |
| PPPM | 400 W - Peak pulse power rating per IEC 61643-321 (10/1000 µs waveform) |
| IRM | 5 µA at VRWM - Ultra-low leakage preserves efficiency in battery-backed or low-power systems |
| Tj max | 185 °C - Enables use in engine compartments, industrial controls, and high-ambient environments |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - Provides system-level ESD immunity without external shielding |
Pinout & Package
The PTVS5V0S1UTR,115 is housed in a SOD123W (CFP3) surface-mount plastic package measuring 2.6 mm × 1.7 mm × 1.0 mm, with flat leads and a cathode-marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., VCC); clamping occurs when voltage exceeds VRWM relative to anode |
| 2 (A) | Anode | Typically tied to ground or low-impedance return path; defines polarity for unidirectional suppression |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rated to 185 °C - eliminates derating in hot environments like motor drives or under-hood ECUs |
| Low-profile SMD package | 1.0 mm height - enables placement beneath connectors or in ultra-thin enclosures without mechanical interference |
| Precision clamping | VCL = 9.2 V at 43.5 A - holds downstream ICs safely below 12 V absolute maximum ratings during surge events |
| Robust ESD immunity | 30 kV contact discharge - meets IEC 61000-4-2 Level 4 without additional board-level protection |
| Stable leakage performance | IRM ≤ 5 µA at 5.0 V - prevents parasitic drain in always-on circuits such as real-time clocks or backup supplies |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: 12 V DC input rail in programmable logic controllers exposed to load dump and inductive switching transients. IC Role / Device Role: Unidirectional TVS diode placed between VIN and GND to clamp surges before they reach DC-DC converters and microcontrollers. Use Value: Withstands 400 W pulses and maintains clamping at 9.2 V, preventing latch-up or damage to 5 V/3.3 V logic downstream. | Use Scenario: LIN bus power rail and sensor supply lines in door modules subject to ISO 7637-2 Pulse 1/2a/5a. IC Role / Device Role: Primary overvoltage clamp on 12 V auxiliary rail feeding window lift motors and mirror actuators. Use Value: Operates reliably at 150 °C ambient and clamps transients within 1 ns, meeting automotive EMC requirements without thermal shutdown. |
| High-Temperature Motor Drive Interface | Medical Equipment DC Power Input |
Use Scenario: Gate driver supply rail in industrial inverters mounted near heat sinks with local ambient >125 °C. IC Role / Device Role: Secondary protection stage after bulk MOV, absorbing fast-rising spikes induced by IGBT switching. Use Value: Stable 5.0 V VRWM and 185 °C Tj rating ensure consistent clamping performance across full thermal operating range. | Use Scenario: 24 V DC input to portable diagnostic devices requiring Class II medical safety compliance and low leakage. IC Role / Device Role: First-line transient suppressor on isolated DC input, preceding DC-DC isolation stage. Use Value: 5 µA IRM at VRWM avoids compromising patient-isolation barrier integrity or battery runtime in battery-operated units. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Lower PPPM (400 W same), but higher VCL = 9.6 V at 43.3 A; VRWM = 5.0 V; SMA package (2.5 mm height) | Less suitable for ultra-low-profile designs due to 2.5 mm height vs. 1.0 mm; identical thermal rating (185 °C) | Select when existing SMA footprint is fixed and height constraint is relaxed. |
| 1.5SMC5.0A | Higher PPPM (1500 W), larger DO-214AB package (4.5 mm height); VRWM = 5.0 V; VCL = 9.2 V at 163 A | Over-specified for 400 W needs; requires more PCB area and has slower response due to higher junction capacitance | Choose only when legacy 1.5 kW surge standards apply and board space allows larger footprint. |
Compared with SMAJ5.0A and 1.5SMC5.0A, the PTVS5V0S1UTR,115 delivers identical clamping performance in a 60 % lower profile package with equal high-temperature capability-making it optimal for next-generation compact, thermally demanding systems.

FAQ
What is the maximum clamping voltage of PTVS5V0S1UTR,115 under a 400 W transient?
The clamping voltage (VCL) is 9.2 V at a peak pulse current (IPPM) of 43.5 A, measured per IEC 61643-321 10/1000 µs waveform. This value is guaranteed across the full operating temperature range (−55 °C to +185 °C ambient) and reflects worst-case device behavior under standardized surge conditions.
Does PTVS5V0S1UTR,115 support bidirectional transient suppression?
No. PTVS5V0S1UTR,115 is a unidirectional TVS diode, configured with cathode (pin 1) and anode (pin 2). It protects against positive transients on the cathode side relative to the anode. For bidirectional protection, two devices in series opposition or a dedicated bidirectional part (e.g., PTVS5V0S1UTR-B) would be required.
How does the 1 mm package height impact PCB layout and thermal performance?
The 1 mm SOD123W profile reduces mechanical interference with adjacent components and enables routing underneath the device. Thermally, its Rth(j-sp) = 18 K/W to the cathode solder point allows efficient heat transfer to copper pours, supporting sustained operation at 185 °C junction temperature without forced airflow or heatsinking.
Is PTVS5V0S1UTR,115 qualified for automotive applications per AEC-Q200?
No. While the device operates up to 185 °C junction temperature and withstands automotive-relevant transients (e.g., ISO 7637-2), it is not AEC-Q200 qualified. Nexperia explicitly states in the datasheet that non-automotive qualified products are not tested to automotive reliability standards-design-in for automotive use requires formal qualification and customer responsibility for validation.
