Product details
Overview
PTVS13VS1UTR 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 = 13 V, VBR(min) = 14.4 V, VCL = 21.5 V at IPPM = 18.6 A (10/1000 µs), and operates up to Tj = 185 °C - enabling robust surge suppression in industrial power management systems.
For engineers reviewing the PTVS13VS1UTR datasheet, PTVS13VS1UTR pinout, PTVS13VS1UTR application, or PTVS13VS1UTR equivalent, this device delivers verified clamping performance under IEC 61643-321 waveforms, low IRM = 0.001 µA at VRWM, and thermal stability critical for automotive-adjacent industrial control units and high-reliability DC power interfaces.
Technical Context
This unidirectional TVS diode uses a planar silicon junction optimized for fast response (<1 ns) to transient surges while maintaining stable breakdown behavior across temperature. Its VBR tolerance (±5%) and low temperature coefficient (SZ = 0.5 mV/K) ensure predictable clamping voltage drift up to 150 °C ambient.
The device complies with IEC 61643-321 (10/1000 µs waveform) and supports non-repetitive peak forward current up to 50 A (tp = 8.3 ms). Its Rth(j-sp) = 18 K/W enables effective heat dissipation through the cathode solder point on standard FR4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 13 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min) | 14.4 V at IR = 1 mA - guaranteed breakdown initiation threshold |
| VCL | 21.5 V at IPPM = 18.6 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 400 W - peak pulse power handling per IEC 61643-321, derated above 25 °C |
| IRM | 0.001 µA at VRWM - ultra-low leakage preserves efficiency in standby-sensitive circuits |
| Tj max | 185 °C - extended junction temperature rating enables use in engine bay or enclosed industrial enclosures |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to cathode solder point, enabling reliable PCB-level thermal management |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body height, flat lead profile, marking bar indicates cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line's higher-potential side; carries surge current to ground when clamping |
| 2 | Anode (A) | Connected to system ground; completes conduction path during transient events |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Tj ≤ 185 °C ensures reliability in under-hood, motor drive, and furnace controller environments |
| Low-profile SMD package | 1.0 mm height enables use in space-constrained power modules and dense PCB layouts |
| Ultra-low reverse leakage | IRM = 0.001 µA minimizes quiescent power loss in battery-backed or energy-harvesting systems |
| Controlled clamping ratio | VCL/VBR = 1.49 ensures tight voltage margin between standoff and protection threshold |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) protects against handling and interface surges |
Applications
| Industrial Power Supply Protection | Motor Drive DC Bus Protection |
|---|---|
Use Scenario: 24 V DC input rail in programmable logic controllers exposed to inductive kickback and lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed across input terminals to clamp transients before they reach upstream regulators and microcontrollers. Use Value: Clamps 18.6 A surges to 21.5 V, preventing damage to 28 V-rated input stages while maintaining <0.001 µA leakage during normal operation. |
Use Scenario: DC link capacitor protection in 3-phase inverter drives where regenerative braking induces voltage spikes. IC Role / Device Role / Timing Role: Parallel-mounted TVS absorbing repetitive switching transients on the high-side DC bus. Use Value: Withstands 185 °C junction temperature and maintains stable VBR across thermal cycling, ensuring consistent clamping during sustained motor overload conditions. |
| Automotive-Grade Battery Management | High-Temperature Sensor Interface Protection |
Use Scenario: 12 V auxiliary supply line in vehicle telematics units operating near engine compartments. IC Role / Device Role / Timing Role: Primary overvoltage clamp on battery-fed power rail, coordinated with fuse and upstream filtering. Use Value: Survives 185 °C ambient exposure and delivers 400 W peak pulse power without degradation, meeting AEC-Q200 adjacent reliability expectations. |
Use Scenario: Signal line protection for RTD or thermocouple interfaces in industrial ovens and kilns. IC Role / Device Role / Timing Role: Low-leakage TVS placed at sensor front-end to suppress ESD and cable-coupled noise without loading millivolt-level signals. Use Value: 0.001 µA IRM avoids measurement offset errors, while 21.5 V clamping prevents ADC input saturation during field wiring faults. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Lower PPPM (400 W same), but VRWM = 13 V, VCL = 21.5 V, Tj max = 150 °C | Limited to lower-temperature industrial environments; not rated for >150 °C continuous operation | Select when cost sensitivity outweighs high-temp requirement and thermal derating is acceptable |
| 1.5SMC13A | Same VRWM/VCL, but larger SMC package (7.1 mm × 6.2 mm × 2.6 mm); PPPM = 1500 W, Tj max = 175 °C | Higher power handling but incompatible footprint; requires PCB redesign and higher board area | Choose only if surge energy exceeds 400 W capability and space permits larger package |
Compared with SMAJ13A and 1.5SMC13A, PTVS13VS1UTR uniquely balances 400 W surge capacity, 1 mm profile, and 185 °C junction rating - making it the only option for compact, high-temperature power rail protection without sacrificing clamping precision or leakage performance.

FAQ
What is the maximum clamping voltage of PTVS13VS1UTR under standard test conditions?
The clamping voltage VCL is 21.5 V at IPPM = 18.6 A using the 10/1000 µs waveform per IEC 61643-321. This value is measured at Tj = 25 °C and represents the maximum voltage seen across the device during a defined surge event - critical for ensuring downstream ICs remain within absolute maximum ratings.
Does PTVS13VS1UTR support bidirectional transient suppression?
No - PTVS13VS1UTR is strictly unidirectional. Its anode-cathode configuration only conducts during reverse-biased overvoltage events. For AC or bipolar signal line protection, a dedicated bidirectional TVS (e.g., PTVS13VS1UTR's dual-diode counterpart) must be selected instead.
How does the 185 °C junction temperature rating impact PCB layout?
The 185 °C Tj rating allows operation in thermally demanding locations, but requires attention to thermal relief: the cathode pad must match the recommended 1 cm² copper area per Nexperia's thermal data (Rth(j-sp) = 18 K/W), and adjacent heat sources should be spaced to avoid cumulative ambient rise beyond 185 °C at the die.
Can PTVS13VS1UTR replace older P6SMB13A in existing designs?
Yes - with caveats. Both share VRWM = 13 V and similar VCL, but PTVS13VS1UTR offers superior thermal capability (185 °C vs. 150 °C), lower leakage (0.001 µA vs. 1 µA), and smaller SOD123W footprint. Layout adaptation is required due to different pad geometry, and thermal validation is recommended for high-power-density boards.
