Product details
Overview
PTVS64VS1UR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) surface-mount package, designed for high-energy transient overvoltage protection in DC power rails. It features a 64 V reverse standoff voltage (VRWM), 78.6 V maximum clamping voltage (VCL) at 103 A peak pulse current (IPPM), and 0.001 µA reverse leakage current at VRWM - enabling robust ESD and surge immunity in space-constrained industrial and automotive-qualified systems.
For engineers reviewing the PTVS64VS1UR,115 datasheet, PTVS64VS1UR,115 pinout, PTVS64VS1UR,115 application, or PTVS64VS1UR,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (18 K/W), AEC-Q101 qualification status, and compatibility with FR4 PCB layouts using standardized SOD123W footprint.
Technical Context
This unidirectional TVS diode operates as a clamping device that remains non-conductive below VRWM = 64 V and rapidly avalanches above its breakdown voltage (VBR = 71.1–78.6 V) to limit transient voltages. Its junction-to-solder-point thermal resistance of 18 K/W supports reliable power dissipation during repetitive surges when mounted on standard PCB copper pads.
The device complies with IEC 61643-321 (10/1000 µs waveform) and achieves 30 kV ESD immunity per IEC 61000-4-2 contact discharge, with a maximum junction temperature rating of 150 °C and storage temperature range from −65 °C to +150 °C - confirming suitability for harsh ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 400 W per IEC 61643-321 10/1000 µs waveform - sustains high-energy transients without failure |
| Reverse Standoff Voltage (VRWM) | 64 V - maximum continuous DC operating voltage before clamping initiates |
| Clamping Voltage (VCL) | 78.6 V at IPPM = 103 A - limits downstream circuit voltage during surge events |
| Breakdown Voltage (VBR) | 71.1 V (min) to 78.6 V (max) at IR = 1 mA - defines precise avalanche onset threshold |
| Reverse Leakage Current (IRM) | 0.001 µA at VRWM - negligible standby power loss and minimal signal path loading |
| Junction-to-Solder-Point Rth | 18 K/W - enables efficient heat transfer from die to PCB cathode pad for thermal reliability |
| ESD Rating (IEC 61000-4-2) | 30 kV contact discharge - exceeds industrial immunity requirements for system-level ESD protection |
Pinout & Package
PTVS64VS1UR,115 uses the CFP3 (SOD123W) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body size, 1 mm profile height, with cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line or ground return; marking bar identifies this terminal |
| 2 | Anode (A) | Connected to system ground or low-impedance reference; completes clamping path during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile (1 mm height) | Enables placement in tight board spaces and under shields without mechanical interference |

| 400 W peak pulse power | Handles high-energy transients such as ISO 7637-2 pulse 1/2a/5a in 12 V vehicle systems |
| SOD123W standard footprint | Compatible with industry-standard reflow and wave soldering processes per Nexperia's recommended land pattern |
| 0.001 µA reverse leakage | Minimizes quiescent current draw in always-on battery-powered circuits |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: Protecting 24 V DC input rails in programmable logic controllers (PLCs) against load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between input rail and chassis ground to shunt surge energy before it reaches DC-DC converters. Use Value: Clamps to ≤78.6 V at 103 A, preventing damage to downstream 36 V-rated regulators and ensuring system uptime during factory floor surges. |
Use Scenario: Safeguarding LIN bus interface and sensor supply lines in BCMs exposed to battery voltage spikes during jump-start or alternator load dump. IC Role / Device Role / Timing Role: Standby protection element connected across 12 V supply and ground, activated only during >64 V overvoltage events. Use Value: 30 kV ESD rating and AEC-Q101 qualification ensure compliance with automotive EMC standards (ISO 11452-2/4) and long-term field reliability. |
| Telecom Remote Radio Unit (RRU) | Smart Meter Power Input Stage |
|
Use Scenario: Securing 48 V PoE-derived power inputs in outdoor RRUs subject to lightning-induced surges on metallic cabling. IC Role / Device Role / Timing Role: Primary front-end TVS on DC input, coordinated with upstream GDT or MOV for staged protection architecture. Use Value: 400 W PPPM rating and 18 K/W Rth(j-sp) allow repeated 10/1000 µs surge handling without thermal runaway on compact PCBs. |
Use Scenario: Shielding meter microcontroller supply rails from grid-side transients entering via AC-DC adapter or battery backup circuitry. IC Role / Device Role / Timing Role: Low-leakage (0.001 µA) unidirectional suppressor placed directly at MCU VDD pin input filter stage. Use Value: Near-zero standby current preserves battery life in tamper-detection circuits while maintaining <80 V clamping during 1 kV/500 A surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A | DO-214AC package (larger: 4.5 × 2.7 × 2.2 mm); 64 V VRWM; 103 V VCL @ 6.5 A; lower PPPM (400 W same, but derated faster above 25 °C) | Less suitable for ultra-thin designs; higher Rth(j-a) (~50 K/W) reduces surge repetition capability on small pads | Select when legacy DO-214AC footprint is fixed and thermal margin exists; avoid where board height <1.1 mm is required |
| SMCJ64A | DO-214AB package (7.1 × 6.2 × 2.6 mm); same 64 V VRWM; 103 V VCL @ 39.5 A; 1500 W PPPM rating | Over-specified for most PCB-level protection; excessive size and cost for SOD123W-targeted layouts | Choose only for high-repetition-rate surge environments requiring >1 kW peak handling; not recommended for space-constrained consumer or automotive modules |
Compared with SMAJ64A and SMCJ64A, PTVS64VS1UR,115 delivers identical 64 V standoff and comparable clamping but in a 70% smaller footprint and with superior thermal coupling to PCB - making it optimal for modern miniaturized power protection where height, layout area, and thermal response are critical.

FAQ
Is PTVS64VS1UR,115 qualified for automotive use?
Yes - PTVS64VS1UR,115 is AEC-Q101 qualified per Nexperia's revision history v.4 (2025), confirming stress-test validation for temperature cycling, humidity, ESD, and surge endurance in automotive environments. Its qualification status is explicitly retained for this part number despite removal for some variants in the series.
What is the maximum allowable junction temperature during surge operation?
The absolute maximum junction temperature is 150 °C per IEC 60134 limiting values. Under a single 10/1000 µs 400 W pulse, junction temperature rise depends on thermal resistance: with Rth(j-sp) = 18 K/W and 103 A IPPM, ΔT ≈ 1.85 K - well within limit. Continuous operation must maintain Tj ≤ 150 °C using appropriate PCB copper area.
How does the 1 mm package height impact PCB assembly?
The 1 mm maximum height enables placement beneath metal shields, in stacked-board assemblies, and in ultra-thin enclosures. Its SOD123W footprint matches IPC-7351B standard land patterns, supporting both reflow (0.1 mm stencil thickness recommended) and wave soldering with defined dummy track clearances per Nexperia's footprint documentation.
Can PTVS64VS1UR,115 replace PTVS64VS1UR without changes?
Yes - PTVS64VS1UR,115 is the tape-and-reel packaged version of PTVS64VS1UR, sharing identical electrical characteristics, thermal performance, and SOD123W mechanical dimensions. The ",115" suffix denotes packaging format (7″ reel, 3000 pcs/reel) and does not affect functionality or layout.
