Product details
Overview
PTVS36VS1UR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) diode in SOD123W (CFP3) package, designed for clamping transient overvoltages on DC power rails. It features VRWM = 36 V, VBR(min) = 40.0 V at IR = 1 mA, VCL(max) = 58.1 V at IPPM = 6.9 A (10/1000 µs), and IRM ≤ 0.001 µA - enabling robust protection of 36 V automotive and industrial power supply inputs against ISO 7637-2 pulses and ESD events.
For engineers reviewing the PTVS36VS1UR,115 datasheet, PTVS36VS1UR,115 pinout, PTVS36VS1UR,115 application, or PTVS36VS1UR,115 equivalent, key selection criteria include clamping voltage margin relative to system rail tolerance, peak pulse current handling under IEC 61643-321 waveform, thermal resistance to PCB copper area, and qualification status for automotive-grade reliability.
Technical Context
This unidirectional TVS operates as a reverse-biased avalanche diode, triggering when transient voltage exceeds its 36 V standoff threshold and clamping to ≤58.1 V within nanoseconds. Its 400 W peak pulse power rating is specified per IEC 61643-321 (10/1000 µs waveform), with junction temperature derating down to ~50% at 125 °C.
The device uses planar silicon junction technology with low leakage (<0.001 µA at VRWM), high ESD robustness (30 kV contact discharge per IEC 61000-4-2), and AEC-Q101 qualification confirmed in revision v.4 (December 2025). Its SOD123W package delivers 1 mm height and 2.6 mm × 1.7 mm footprint for space-constrained board layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 36 V - maximum continuous reverse operating voltage before breakdown; sets minimum system rail margin for safe operation. |
| VBR (min) | 40.0 V at IR = 1 mA - guaranteed avalanche initiation voltage; ensures reliable turn-on above nominal rail. |
| VCL (max) | 58.1 V at IPPM = 6.9 A (10/1000 µs) - peak clamped voltage seen by protected circuit; defines worst-case stress during surge. |
| PPPM | 400 W - rated peak pulse power handling capability under standardized surge waveform; determines survivability of common transients. |
| IRM | ≤0.001 µA at VRWM - ultra-low reverse leakage; minimizes quiescent power loss and avoids false triggering in high-impedance circuits. |
| Rth(j-a) | 220 K/W (FR4, single-sided copper) - thermal resistance defining junction-to-ambient temperature rise under sustained power dissipation. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2); >4 kV HBM - qualifies for direct interface with external connectors subject to human-handling ESD. |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2-terminal, 2.6 mm × 1.7 mm × 1.0 mm body, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +36 V rail); reverse-biased during normal operation; conducts surge current to ground when clamping. |
| 2 (A) | Anode | Connected to system ground reference; completes current path during transient event; must be low-inductance connection for effective clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Peak pulse power | 400 W (IEC 61643-321 10/1000 µs) - enables suppression of high-energy load-dump and inductive-switching transients without failure. |
| Low profile | 1.0 mm max height - supports ultra-thin designs in automotive ECUs and portable industrial controllers where Z-axis space is constrained. |
| AEC-Q101 qualified | Qualified per revision v.4 (Dec 2025) - validated for automotive power supply protection including engine control, body electronics, and ADAS modules. |
| Ultra-low leakage | IRM ≤ 0.001 µA at VRWM - eliminates measurable standby current contribution in always-on 36 V systems (e.g., telematics battery backup). |
| High ESD immunity | 30 kV contact discharge - protects against field-level ESD events on exposed power inputs without requiring additional series impedance. |
Applications
| Automotive Power Rail Protection | Industrial 36 V DC Power Supply |
|---|---|
|
Use Scenario: Protecting 36 V battery-fed circuits in commercial vehicle ECUs against ISO 7637-2 Pulse 5a (load dump) and Pulse 1 (inductive switching). IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and downstream DC-DC converter input; clamps transients within <1 ns. Use Value: Limits voltage excursion to ≤58.1 V, preserving input stage MOSFETs and gate drivers rated for 60 V absolute maximum. |
Use Scenario: Safeguarding programmable logic controller (PLC) 36 V auxiliary power input from surges induced by relay coil de-energization or motor drive noise. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main DC bus; coordinated with upstream fuse and downstream bulk capacitance. Use Value: Absorbs 400 W peak energy without degradation, maintaining system uptime in harsh factory environments. |
| Telematics Module Battery Backup | 48 V Mild Hybrid Vehicle Interface |
|
Use Scenario: Securing always-on 36 V backup rail in fleet-tracking telematics units connected to vehicle battery via ignition-switched harness. IC Role / Device Role / Timing Role: Standoff-mode protector on non-isolated backup path; blocks leakage while responding to fast-rising transients. Use Value: 0.001 µA IRM prevents measurable drain on backup supercapacitor over multi-year deployment. |
Use Scenario: Front-end transient suppression on 36 V auxiliary rail derived from 48 V mild hybrid architecture (e.g., 48 V → 36 V DC-DC output). IC Role / Device Role / Timing Role: Secondary clamping stage after primary 48 V TVS; handles residual overshoot and coupling artifacts. Use Value: Matches 36 V rail tolerance with 40.0–44.2 V VBR range and 58.1 V VCL, ensuring no downstream component exceeds its 60 V rating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PTVS36VS1UTR | Same electrical specs but in SOD123 (not SOD123W); 1.35 mm height vs. 1.0 mm; Rth(j-a) = 250 K/W (vs. 220 K/W). | Less suitable for ultra-low-profile automotive modules; higher thermal resistance reduces sustained surge margin. | Select only if legacy SOD123 footprint compatibility is required and height constraint is relaxed. |
| SMAJ36A | DO-214AC package; VRWM = 36 V, VCL = 58.1 V, PPPM = 400 W; IRM = 1 µA (1000× higher than PTVS36VS1UR). | Higher leakage limits use in battery-backed always-on systems; larger footprint (4.3 × 2.6 mm) consumes more board area. | Prefer when cost is prioritized over size/leakage and DO-214AC assembly infrastructure exists. |
Compared with PTVS36VS1UR,115, the PTVS36VS1UTR trades height and thermal performance for legacy footprint compatibility, while SMAJ36A offers identical clamping but sacrifices leakage performance and board space efficiency - making the SOD123W variant optimal for next-gen compact, low-power automotive and industrial designs.

FAQ
What is the clamping voltage of PTVS36VS1UR,115 under a 10/1000 µs surge?
The maximum clamping voltage (VCL) is 58.1 V at peak pulse current (IPPM) of 6.9 A, measured per IEC 61643-321 standard. This value is guaranteed across temperature and process variation, and defines the upper voltage limit imposed on protected circuitry during surge events.
Is PTVS36VS1UR,115 qualified for automotive use?
Yes - revision v.4 of the datasheet (December 2025) confirms AEC-Q101 qualification for PTVS36VS1UR,115. The device has passed stress tests for temperature cycling, humidity, mechanical shock, and high-temperature operating life, making it suitable for engine bay and chassis-mounted automotive applications.
How does the SOD123W package improve thermal performance over standard SOD123?
The SOD123W (CFP3) package reduces thermal resistance from junction to ambient to 220 K/W (vs. 250 K/W for SOD123) due to optimized die attach and thinner molding compound. Its 1.0 mm height also improves heat conduction to PCB copper, supporting higher sustained surge duty cycles in thermally dense layouts.
What is the reverse leakage current specification at 36 V standoff?
The reverse leakage current (IRM) is guaranteed ≤0.001 µA at VRWM = 36 V and Tj = 25 °C. This ultra-low value is verified per test condition in Table 8 and ensures negligible impact on battery life in always-on 36 V systems such as telematics and remote monitoring units.
