Product details
Overview
PTVS36VS1UTR-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 VRWM = 36 V, VBR(min) = 40.0 V, VCL = 58.1 V at IPPM = 6.9 A (10/1000 µs), and operates up to Tj = 185 °C.
For engineers reviewing the PTVS36VS1UTR-Q datasheet, PTVS36VS1UTR-Q pinout, PTVS36VS1UTR-Q application, or PTVS36VS1UTR-Q equivalent, this device is selected for robust clamping in 12 V–48 V automotive subsystems where AEC-Q101 qualification, low-profile mounting, and thermal stability are critical.
Technical Context
This unidirectional TVS diode uses a planar silicon junction optimized for fast response (<1 ns) to ESD and surge transients per IEC 61643-321 (10/1000 µs). Its clamping behavior is defined by a sharp breakdown knee with SZ = 0.5 mV/K temperature coefficient, ensuring stable VBR across -55 °C to +150 °C operating range.
The device sustains non-repetitive peak forward current up to 50 A (tp = 8.3 ms) and delivers 30 kV ESD immunity (IEC 61000-4-2 contact/air discharge), with Rth(j-sp) = 18 K/W enabling effective heat transfer through the cathode solder point in high-power pulse events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 36 V - Maximum continuous reverse operating voltage before significant leakage; sets system rail compatibility for 36 V nominal circuits. |
| VBR (min) | 40.0 V - Minimum breakdown voltage at IR = 1 mA; guarantees reliable turn-on above normal operating voltage. |
| VCL @ IPPM | 58.1 V - Clamping voltage at 6.9 A peak pulse current; limits downstream voltage stress during 10/1000 µs surges. |
| PPPM | 400 W - Rated peak pulse power per IEC 61643-321; defines maximum single-event energy absorption capability. |
| IRM | 0.001 µA - Reverse leakage current at VRWM; ensures minimal standby power loss and signal integrity in high-impedance nodes. |
| Tj max | 185 °C - Maximum junction temperature; enables operation in under-hood automotive environments without derating. |
| ESD rating | 30 kV - Human-body-model (HBM) and IEC 61000-4-2 contact/air discharge rating; qualifies for direct board-level ESD protection. |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body height, flat lead profile optimized for automated placement and thermal relief on PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., battery rail); marking bar identifies this terminal; carries full surge current during clamping. |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance path to GND during transient events; requires low-inductance layout. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Stress-tested per Automotive Electronics Council standard for discrete semiconductors; validated for under-hood automotive use. |
| Low-profile SOD123W | 1.0 mm max height enables integration in space-constrained modules (e.g., ECUs, ADAS sensors) without mechanical interference. |
| High-temperature stability | Rated for continuous operation at Tamb = –55 °C to +185 °C; maintains VBR and clamping performance across full automotive temperature range. |
| 400 W pulse rating | Supports IEC 61000-4-5 Level 4 surge immunity (1 kV/2 Ω) in 12 V systems and higher-energy transients in 24 V/48 V architectures. |
| Ultra-low leakage | IRM ≤ 0.001 µA at VRWM minimizes quiescent current draw-critical for always-on automotive modules with strict sleep-mode budgets. |
Applications
| Automotive Power Rail Protection | Industrial DC Power Input |
|---|---|

| Automotive Lighting Systems | High-Temperature Sensor Interfaces |
|
Use Scenario: Shielding LED driver ICs in headlamp modules from alternator ripple and ignition-induced spikes in engine bay environments. IC Role / Device Role / Timing Role: Fast-response TVS on driver supply rail, turning on before internal FETs experience overvoltage stress. Use Value: Reduces need for additional RC snubbers or larger capacitors by providing precise 58.1 V clamping with <1 ns response time. |
Use Scenario: Protecting analog front-ends of exhaust gas temperature (EGT) or turbocharger sensors operating near hot engine components. IC Role / Device Role / Timing Role: Localized transient suppression at sensor connector interface, minimizing trace inductance impact via SOD123W low-inductance layout. Use Value: Maintains signal fidelity under sustained 150 °C ambient by leveraging 0.5 mV/K VBR temperature coefficient and 185 °C Tj rating. |
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-Q | Lower PPPM (400 W same), but VRWM = 36 V, VCL = 58.1 V, and AEC-Q101 qualified; SMA package (higher profile: 2.3 mm). | Less suitable for ultra-low-height modules; requires larger PCB footprint and has higher Rth(j-a) = 70 K/W vs. 18 K/W (j-sp). | Select when legacy SMA footprint compatibility is required and height constraint is relaxed. |
| TPSMF36A | Same VRWM/VCL/PPPM, but SOD-123FL package (1.2 mm height); not AEC-Q101 qualified; IRM = 0.1 µA (100× higher than PTVS36VS1UTR-Q). | Not approved for automotive safety-critical functions; higher leakage may affect low-power sensor bias networks. | Select only for cost-sensitive industrial applications where AEC-Q101 and sub-µA leakage are not mandatory. |
Compared with SMAJ36A-Q and TPSMF36A, PTVS36VS1UTR-Q uniquely combines AEC-Q101 qualification, 1.0 mm profile, 0.001 µA leakage, and 18 K/W junction-to-solder-point thermal resistance-making it optimal for space- and reliability-constrained automotive electronics.

FAQ
What is the clamping voltage of PTVS36VS1UTR-Q at its rated peak pulse current?
The clamping voltage (VCL) is 58.1 V at IPPM = 6.9 A under 10/1000 µs waveform conditions, measured at Tj = 25 °C. This value ensures protected circuitry remains below critical overvoltage thresholds during standardized surge events.
Does PTVS36VS1UTR-Q meet automotive qualification standards?
Yes-it is fully qualified to AEC-Q101 for stress testing of discrete semiconductors and explicitly recommended for automotive applications, including under-hood environments with ambient temperatures up to +185 °C.
How does the SOD123W package improve thermal performance compared to standard SOD-123?
The SOD123W (CFP3) variant features an extended cathode pad that reduces Rth(j-sp) to 18 K/W-significantly lower than standard SOD-123's typical 50–70 K/W-enabling more efficient heat transfer to the PCB during high-energy transient events.
Can PTVS36VS1UTR-Q be used in bidirectional protection configurations?
No-it is a unidirectional TVS diode with cathode/anode polarity; bidirectional protection requires either two devices in series opposition or a dedicated bidirectional part such as PTVS36VS1UTR-Q's complementary series variant PTVS36VS1UTR-QB (not offered in this series).
