Product details
Overview
PTVS36VS1UTR from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature overvoltage protection with VRWM = 36 V, VBR(min) = 40.0 V, VCL = 58.1 V at IPPM = 6.9 A, and Tj ≤ 185 °C - deployed in industrial power management and automotive under-hood circuits.
For engineers reviewing the PTVS36VS1UTR datasheet, PTVS36VS1UTR pinout, PTVS36VS1UTR application, or PTVS36VS1UTR equivalent, this page delivers verified thermal limits, clamping behavior under IEC 61643-321 10/1000 µs pulses, junction-to-solder-point thermal resistance (18 K/W), and cathode/anode terminal mapping for PCB layout and reliability validation.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transient surges, with reverse standoff voltage VRWM = 36 V ensuring stable blocking below 36 V DC bias, and precise breakdown at VBR = 40.0–44.2 V (min–max) at 1 mA test current. Its unidirectional polarity enables integration into DC-biased signal or power rails where forward conduction must be avoided.
Thermal design is enabled by Rth(j-sp) = 18 K/W (junction-to-solder point), validated on FR4 PCB with cathode pad, supporting sustained operation up to Tj = 185 °C - critical for engine control units and industrial motor drives exposed to ambient temperatures up to +185 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 36 V - maximum continuous reverse voltage before significant leakage; defines safe operating window for 36 V nominal systems. |
| VBR (min) | 40.0 V - guaranteed avalanche initiation voltage at 1 mA; ensures predictable clamping onset above system rail. |
| VCL @ IPPM | 58.1 V - clamped voltage at 6.9 A peak pulse; determines maximum stress on protected IC during surge. |
| PPPM | 400 W - rated peak pulse power per IEC 61643-321 (10/1000 µs); supports robust ESD and lightning surge immunity. |
| Tj max | 185 °C - maximum junction temperature; enables use in under-hood automotive and high-temp industrial environments. |
| Rth(j-sp) | 18 K/W - thermal resistance to solder point; guides copper pour sizing for thermal relief in high-power transients. |
| IRM | 0.001 µA - reverse leakage at VRWM; negligible loading on 36 V supply rails at elevated temperatures. |
Pinout & Package
The device uses a 2-terminal SOD123W (CFP3) surface-mount plastic package measuring 2.6 mm × 1.7 mm × 1.0 mm, with low-profile construction optimized for space-constrained PCB layouts and automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to system ground or lower-potential node; marking bar identifies this terminal for correct orientation during placement. |
| 2 (A) | Anode | Connected to protected line (e.g., 36 V rail); reverse-biased during normal operation, avalanches during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Rated for continuous operation up to Tj = 185 °C - eliminates derating in engine control modules and industrial inverters. |
| Precision clamping | VCL = 58.1 V at 6.9 A ensures protected downstream ICs see <59 V during worst-case surge, preserving 60 V-rated components. |
| Low-profile SMD package | SOD123W footprint (2.6 × 1.7 mm) fits dense power supply layouts while maintaining 400 W surge capability. |
| Ultra-low leakage | IRM = 0.001 µA at VRWM minimizes standby current drain in battery-backed or energy-sensitive 36 V systems. |
| IEC 61643-321 compliance | Validated for 10/1000 µs waveform - meets international standards for AC/DC power port surge immunity testing. |
Applications
| Industrial Motor Drives | Automotive Engine Control Units |
|---|---|
Use Scenario: Protection of 36 V DC bus against load dump and inductive switching spikes in brushless motor controllers. IC Role / Device Role: Unidirectional TVS placed between 36 V rail and chassis ground to clamp transients exceeding 44 V.

IC Role / Device Role: Standoff protection element mounted directly at connector entry, leveraging 185 °C Tj rating. Use Value: Maintains <0.001 µA leakage and stable VBR across full temperature range, avoiding false triggers or drift-induced failure. |
| Telecom Power Supplies | Renewable Energy Inverters |
Use Scenario: Input-stage protection for 36 V telecom rectifier modules subjected to lightning-induced surges on outdoor lines. IC Role / Device Role: Primary clamping device on DC input, coordinated with upstream MOVs for multi-level protection. Use Value: Delivers 400 W peak pulse handling with 58.1 V clamping, reducing stress on downstream DC-DC converters and PMICs. | Use Scenario: Overvoltage safeguard on 36 V auxiliary control rails in solar string inverters operating in desert environments. IC Role / Device Role: High-reliability TVS mounted near microcontroller power input, thermally anchored to heatsink via cathode pad. Use Value: Rth(j-sp) = 18 K/W enables direct thermal coupling to metal-core PCB, sustaining repeated 400 W pulses without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A | Lower PPPM = 400 W but higher VCL = 58.7 V at same IPPM; VRWM = 36 V identical; Rth(j-a) = 70 K/W vs. 18 K/W (j-sp). | Less effective thermal management in high-density layouts; requires larger copper area for equivalent cooling. | Select when legacy SMA footprint compatibility is required and thermal constraints allow higher ambient rise. |
| 1.5SMC36A | Higher package volume (DO-214AB); PPPM = 1500 W but VCL = 58.1 V at 25.8 A - not directly comparable pulse-current scaling. | Over-specified power rating increases board area and cost; unsuitable for space-constrained SOD123W designs. | Choose only if system-level surge tests require >400 W margin and PCB real estate permits DO-214AB footprint. |
Compared with SMAJ36A and 1.5SMC36A, PTVS36VS1UTR uniquely combines SOD123W miniaturization, 18 K/W junction-to-solder thermal path, and guaranteed 0.001 µA leakage at 185 °C - making it optimal for thermally aggressive, space-limited 36 V protection where long-term reliability outweighs raw power headroom.

FAQ
What is the maximum clamping voltage of PTVS36VS1UTR under standard test conditions?
The clamping voltage VCL is 58.1 V at IPPM = 6.9 A, measured per IEC 61643-321 (10/1000 µs waveform) with Tj = 25 °C. This value remains stable across the full operating temperature range up to 185 °C, as confirmed in Table 8 of the datasheet.
Does PTVS36VS1UTR support bidirectional transient suppression?
No - PTVS36VS1UTR is a unidirectional TVS diode, with cathode (K) and anode (A) terminals clearly defined. It conducts only during reverse overvoltage events and blocks forward current; bidirectional protection requires a separate symmetric device or dual-diode configuration.
How does the SOD123W package affect thermal performance compared to larger packages?
The SOD123W package achieves Rth(j-sp) = 18 K/W by optimizing the cathode thermal path to the PCB solder joint - significantly lower than typical Rth(j-a) values (e.g., 70 K/W). This enables efficient heat extraction without external heatsinks, provided the cathode pad is adequately sized per Nexperia's footprint guidelines.
Is PTVS36VS1UTR qualified for automotive applications?
While not AEC-Q200 qualified, PTVS36VS1UTR is explicitly designed for high-temperature operation up to Tj = 185 °C and used in automotive under-hood ECUs. Its qualification status must be verified separately per OEM requirements; Aetrix provides full traceability and application support for such deployments.
