Product details
Overview
PTVS45VP1UP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-energy transient suppression in DC power rails. It features 45 V reverse standoff voltage (VRWM), 55.3 V maximum clamping voltage (VCL) at 72.7 A peak pulse current (IPPM), and 0.001 µA reverse leakage at VRWM - enabling robust overvoltage protection in space-constrained industrial and power management systems.
For engineers reviewing the PTVS45VP1UP,115 datasheet, PTVS45VP1UP,115 pinout, PTVS45VP1UP,115 application, or PTVS45VP1UP,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (12 K/W), AEC-Q101 qualification status per revision history, and compatibility with reflow/wave soldering footprints for SOD128.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: it remains high-impedance below 45 V VRWM, then avalanches sharply at 50.0–52.65 V breakdown (VBR), limiting transient energy by diverting up to 72.7 A (IPPM) while holding VCL ≤ 55.3 V. Its response is governed by silicon PN-junction avalanche physics, not active circuitry.
Thermal design relies on low Rth(j-sp) = 12 K/W to the cathode solder point, enabling sustained surge handling without junction overheating. The device follows IEC 61643-321 (10/1000 µs) test conditions and supports ESD immunity up to 30 kV (IEC 61000-4-2 contact discharge).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - sustains single 10/1000 µs transients up to this energy level without failure |
| Reverse Standoff Voltage (VRWM) | 45 V - maximum continuous DC operating voltage before leakage exceeds 0.001 µA |
| Clamping Voltage (VCL) | 55.3 V max at IPPM = 72.7 A - defines worst-case rail voltage during surge, protecting downstream ICs |
| Breakdown Voltage (VBR) | 50.0–52.65 V at IR = 1 mA - precise avalanche onset ensures predictable turn-on margin above VRWM |
| Junction-to-Solder-Point Rth | 12 K/W - enables efficient heat transfer from die to PCB copper, critical for repeated surge duty |
| ESD Rating (IEC 61000-4-2) | 30 kV contact discharge - provides system-level ESD robustness without external shielding |
Pinout & Package
SOD128 (CFP5) surface-mount plastic package: 2-terminal, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, marking bar denotes cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., +12 V rail); carries full surge current during clamping |
| 2 | Anode (A) | Connected to ground reference; forms low-inductance return path for transient current |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse rating | Enables protection against severe load-dump and ISO 7637-2 pulses in industrial power supplies |
| 1 mm profile height | Permits placement beneath connectors or in ultra-thin enclosures without mechanical interference |
| AEC-Q101 qualified (per revision history) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
| Low 0.001 µA IR at VRWM | Minimizes standby power loss in battery-backed or energy-sensitive applications |
Applications
| Industrial Power Supply Protection | DC Motor Drive Input Stage |
|---|---|
|
Use Scenario: 48 V DC input rail in programmable logic controller (PLC) power module exposed to inductive switching spikes. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between +48 V and GND, clamping transients within 1 ns. Use Value: Limits voltage excursion to ≤55.3 V during 72.7 A surges, preventing damage to upstream DC-DC controllers and downstream FPGA power domains. |
Use Scenario: H-bridge motor driver board with 24–48 V bus, subject to back-EMF spikes during rapid deceleration. IC Role / Device Role / Timing Role: TVS mounted directly across bus terminals to clamp flyback energy before it propagates into gate drivers. Use Value: Absorbs 600 W transient energy without degradation, maintaining bus integrity and eliminating need for bulkier MOV-based solutions. |
| Telecom Equipment Power Entry | Smart Building Sensor Node Power Input |
|
Use Scenario: PoE-powered network switch with 57 V nominal input, vulnerable to lightning-induced surges on Ethernet lines. IC Role / Device Role / Timing Role: Primary TVS on DC input stage, coordinated with secondary protection on data lines.

Use Scenario: Battery-operated environmental sensor node powered via 12 V wall adapter, deployed in electrically noisy HVAC ducts. IC Role / Device Role / Timing Role: Low-leakage (0.001 µA) TVS on input filter stage, preserving microamp-level sleep current. Use Value: Delivers 600 W surge capability while adding negligible quiescent load - extending 10-year battery life targets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ45A | DO-214AC package; 45 V VRWM; 70 V VCL @ 7.5 A; lower PPPM (400 W) | Larger footprint (4.5 × 2.7 mm vs. 3.8 × 2.6 mm); higher thermal resistance | Choose when legacy DO-214AC layout exists and 400 W rating suffices |
| SMCJ45A | DO-214AB package; same 45 V VRWM; 73 V VCL @ 12.5 A; 1500 W PPPM | 3× larger body (7.1 × 6.2 mm); 3× higher clamping voltage degrades downstream IC margin | Prefer only when multi-kW surge immunity is required and board space permits |
Compared with SMAJ45A and SMCJ45A, PTVS45VP1UP,115 delivers optimal balance of compact SOD128 footprint, 600 W rating, and tight 55.3 V clamping - making it ideal for modern high-density industrial and telecom power designs where both space and voltage margin are constrained.

FAQ
Is PTVS45VP1UP,115 qualified for automotive use?
Yes - per the revision history in the official Nexperia datasheet (v.3, Dec 2025), PTVS45VP1UP,115 is explicitly listed among the 25 types upgraded to standard AEC-Q101 qualification, confirming its suitability for automotive power rail protection where automotive-grade reliability is mandated.
What is the maximum clamping voltage at rated surge current?
The maximum clamping voltage (VCL) for PTVS45VP1UP,115 is 55.3 V at 72.7 A peak pulse current (IPPM), measured under IEC 61643-321 10/1000 µs waveform conditions - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings during surge events.
How does the SOD128 package affect thermal performance?
The SOD128 (CFP5) package achieves Rth(j-sp) = 12 K/W to the cathode solder point due to its optimized copper tab geometry and low-profile thermal path - enabling effective heat dissipation during repetitive surges without requiring additional heatsinking or thermal vias in most industrial PCB layouts.
Can PTVS45VP1UP,115 replace older P6KE45CA in existing designs?
No - PTVS45VP1UP,115 is unidirectional, while P6KE45CA is bidirectional; substituting requires verifying circuit polarity and revising layout to accommodate the SOD128 footprint (3.8 × 2.6 mm) versus DO-15 (9.5 × 4.5 mm), as well as validating clamping behavior under actual system surge profiles.
