Product details
Overview
PTVS40VP1UP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-energy transient suppression on DC power rails. It features 40 V reverse standoff voltage (VRWM), 49.1 V clamping voltage (VCL) at 64.5 A peak pulse current (IPPM), and 0.001 µA reverse leakage at VRWM - optimized for industrial power supply protection with 1 mm profile and AEC-Q101 qualification.
For engineers reviewing the PTVS40VP1UP,115 datasheet, PTVS40VP1UP,115 pinout, PTVS40VP1UP,115 application, or PTVS40VP1UP,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (12 K/W), junction temperature limit (150 °C), and compatibility with automated SMT reflow per JEDEC J-STD-020.
Technical Context
This unidirectional TVS diode operates as a shunt protector: it remains high-impedance below VRWM = 40 V, then avalanches sharply at VBR = 44.4–49.1 V to clamp transients. Its silicon PN junction is engineered for low dynamic impedance during surge events, delivering consistent VCL ≤ 49.1 V at IPPM = 64.5 A per IEC 61643-321.
The device uses a planar passivated chip in a flat-lead SOD128 plastic package with cathode-marked terminal layout. Thermal design leverages direct cathode tab conduction (Rth(j-sp) = 12 K/W), enabling reliable power dissipation in compact industrial PCB layouts without heatsinks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains single 10/1000 µs surges up to 600 W without degradation |
| Reverse Standoff Voltage | VRWM = 40 V - maximum continuous DC operating voltage before leakage exceeds 0.001 µA |
| Clamping Voltage | VCL = 49.1 V at IPPM = 64.5 A - limits downstream circuit voltage during worst-case surge |
| Breakdown Voltage | VBR = 44.4–49.1 V at IR = 1 mA - precise avalanche onset ensures predictable turn-on margin |
| Thermal Resistance | Rth(j-sp) = 12 K/W - enables efficient heat transfer from junction to solder point on PCB |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - protects against human-body and system-level ESD events |
| Package | SOD128 (CFP5) - 3.8 × 2.6 × 1.0 mm surface-mount footprint with 4 mm lead pitch |
Pinout & Package
SOD128 (CFP5) is a 2-terminal, flat-lead surface-mount plastic package with 1 mm maximum height, optimized for high-density PCB layouts and automated assembly. The cathode is marked by a bar on the package body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line; carries full surge current during clamping; marking bar identifies this terminal |
| 2 | Anode (A) | Connected to ground reference; completes low-impedance path for transient energy dissipation |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse rating | Meets IEC 61643-321 for robust protection against lightning-induced and inductive-switching transients |
| 1 mm profile | Enables ultra-low-profile board designs in space-constrained industrial and telecom power modules |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per AEC standard |
| 0.001 µA reverse leakage | Minimizes standby power loss in always-on systems such as battery-backed controllers and IoT edge nodes |
| 12 K/W junction-to-solder-point Rth | Supports sustained surge handling without external thermal relief in standard FR4 PCB layouts |
Applications
| Industrial Power Supply Protection | Telecom DC Power Distribution |
|---|---|
Use Scenario: 48 V DC input rail in programmable logic controller (PLC) power module exposed to load dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between +48 V and GND to clamp transients before they reach DC-DC converters. Use Value: Clamps to ≤49.1 V at 64.5 A, protecting downstream 50 V-rated MOSFETs and controllers without derating. |
Use Scenario: -48 V telecom rectifier output feeding remote radio units (RRUs) over long cables susceptible to induced surges. IC Role / Device Role / Timing Role: Cathode tied to -48 V rail, anode to chassis ground - suppresses positive-going transients on negative supply. Use Value: 600 W rating handles repeated 10/1000 µs surges per GR-1089-CORE; 30 kV ESD withstand prevents field failures. |
| Factory Automation I/O Module | Smart Energy Meter Power Input |
Use Scenario: 24 V auxiliary supply powering digital I/O expansion cards in harsh factory environments with motor drive noise. IC Role / Device Role / Timing Role: TVS mounted directly at connector entry point to intercept fast transients before entering isolation barrier. Use Value: 40 V VRWM matches 24 V nominal + 25% tolerance; 1 mm height fits under shield cans in modular I/O enclosures. |
Use Scenario: M-Bus or PLC communication interface powered from 230 V AC via integrated SMPS with 12 V DC intermediate rail. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12 V rail upstream of metering IC and real-time clock backup circuitry. Use Value: 0.001 µA IR ensures <1 nW leakage - critical for >10-year battery-backed RTC operation in utility meters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ40A | DO-214AA package (2.7 mm height); 40 V VRWM; VCL = 64.5 V at 6.5 A (lower IPPM) | Lower peak current capability (6.5 A vs. 64.5 A); less suitable for high-energy industrial surges | Select when board height >1 mm is acceptable and surge energy is limited to <100 W |
| SMCJ40A | DO-214AB package (2.6 mm height); same VRWM; VCL = 64.5 V at 43.5 A (IPPM lower than PTVS40VP1UP) | Higher Rth(j-a) (35 K/W vs. 60 K/W); requires larger copper area for thermal management | Choose for legacy DO-214AB footprint compatibility where SOD128 rework is not feasible |
Compared with SMBJ40A and SMCJ40A, PTVS40VP1UP,115 delivers 10× higher IPPM in half the height, with superior thermal coupling to PCB - making it optimal for next-generation compact, high-reliability industrial power rails where surge energy and board space are critical constraints.

FAQ
What is the maximum junction temperature for continuous operation?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134 limiting values. For reliable long-term operation, junction temperature should be maintained below 125 °C under worst-case ambient and power dissipation conditions, using thermal design guidance from Table 6 (Rth(j-sp) = 12 K/W).
Does PTVS40VP1UP,115 meet automotive qualification requirements?
Yes - PTVS40VP1UP,115 is AEC-Q101 qualified per Section 11 of the datasheet, having passed stress tests for high-temperature reverse bias, temperature cycling, and ESD. However, revision history confirms that automotive qualification applies only to specific part numbers; PTVS40VP1UP,115 is among the qualified variants.
How does the 10/1000 µs waveform affect clamping performance?
The 10/1000 µs waveform (per IEC 61643-321) defines the standardized surge test condition: 10 µs rise time, 1000 µs decay to 50% peak. PTVS40VP1UP,115 achieves VCL = 49.1 V at IPPM = 64.5 A under this exact waveform - ensuring repeatable, certified clamping behavior in real-world surge events.
Can this TVS be used in bidirectional configurations?
No - PTVS40VP1UP,115 is unidirectional only, with cathode (pin 1) and anode (pin 2) terminals. Bidirectional protection requires either two devices in series opposition or a dedicated bidirectional TVS (e.g., PTVS40VB1UP). Using this part in reverse bias beyond VRWM risks permanent damage.
