Product details
Overview
PTVS48VS1UTR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in power rails. It features VRWM = 48 V, VBR(min) = 53.3 V, VCL = 77.4 V at IPPM = 5.2 A (10/1000 µs), and operates up to Tj = 185 °C - enabling robust surge suppression in industrial power management systems.
For engineers reviewing the PTVS48VS1UTR,115 datasheet, PTVS48VS1UTR,115 pinout, PTVS48VS1UTR,115 application, or PTVS48VS1UTR,115 equivalent, key selection criteria include clamping voltage under 78 V at 5.2 A, thermal resistance as low as 18 K/W (junction-to-solder point), reverse leakage ≤0.001 µA at VRWM, and compatibility with reflow/wave soldering per SOD123W footprint.
Technical Context
This unidirectional TVS diode uses silicon avalanche breakdown to clamp transients above its reverse standoff voltage (VRWM = 48 V). Its VBR range (53.3–58.9 V) ensures reliable triggering before downstream IC damage, while temperature coefficient SZ = 0.5 mV/K maintains stable clamping across –55 °C to +185 °C ambient.
The device complies with IEC 61643-321 (10/1000 µs waveform) and supports ESD immunity of ≥30 kV (contact discharge) and >8 kV (HBM). Its SOD123W package enables low-profile mounting with thermal resistance Rth(j-sp) = 18 K/W when soldered to cathode pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 48 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min) | 53.3 V - guaranteed breakdown voltage at 1 mA, ensuring predictable turn-on margin |
| VCL @ IPPM | 77.4 V at 5.2 A - peak clamped voltage during 10/1000 µs surge, limiting stress on protected circuitry |
| PPPM | 400 W - rated peak pulse power handling capability per IEC 61643-321 |
| IRM | ≤0.001 µA at VRWM - ultra-low leakage preserves efficiency in high-impedance bias networks |
| Tj max | 185 °C - extended junction temperature rating enables use in under-hood or enclosed industrial environments |
| Rth(j-sp) | 18 K/W - low thermal resistance from junction to cathode solder point improves power dissipation reliability |

Applications
| Industrial Power Supply Protection | Motor Drive DC Bus Clamping |
|---|---|
Use Scenario: Protecting 48 V DC input rails in programmable logic controllers (PLCs) and remote I/O modules against lightning-induced surges and inductive switching spikes. IC Role / Device Role / Timing Role: Unidirectional TVS placed between DC input and chassis ground to shunt transient energy before it reaches upstream regulators or microcontrollers. Use Value: Clamps 400 W surges to ≤77.4 V, preventing latch-up or permanent damage to 60 V-rated DC-DC converters and isolated gate drivers. | Use Scenario: Safeguarding the high-side DC bus in 48 V BLDC motor inverters against voltage spikes generated during MOSFET commutation or regenerative braking. IC Role / Device Role / Timing Role: Fast-response avalanche diode connected across bus terminals to suppress dV/dt transients within nanoseconds. Use Value: Limits bus overvoltage to <78 V during 5.2 A transients, preserving IGBT/MOSFET SOA and avoiding desaturation faults. |
| Telecom Power Interface | High-Temperature Sensor Node Protection |
Use Scenario: Shielding 48 V phantom-powered Ethernet (PoE++) interfaces and base station power inputs from induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary overvoltage clamp on the DC feed line, positioned ahead of DC-DC conversion and isolation stages. Use Value: Withstands repeated 400 W pulses while maintaining VRWM stability up to 185 °C - critical for outdoor telecom cabinets exposed to solar heating. | Use Scenario: Protecting analog front-ends and ADC reference rails in automotive-grade temperature sensors deployed near exhaust manifolds or in engine bays. IC Role / Device Role / Timing Role: Localized TVS mounted directly at sensor module input to suppress ESD and load-dump transients before signal conditioning. Use Value: Delivers <0.001 µA leakage at 48 V and stable clamping across –40 °C to +150 °C ambient - ensuring accuracy and longevity in harsh thermal cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ48A | Lower PPPM (400 W same), but higher VCL = 77.4 V vs. SMAJ48A's 77.4 V; identical VRWM and package; slightly higher IRM (1 µA vs. 0.001 µA) | Same 48 V rail protection use case; less suitable for ultra-low-leakage precision analog rails | Select PTVS48VS1UTR,115 where sub-nA leakage or extended Tj (185 °C) is required |
| 1.5SMC47A | Higher power rating (1500 W), larger DO-214AB package (4.5 mm × 3.9 mm), VCL = 77.0 V, VRWM = 45.1 V - not a direct replacement due to lower VRWM and footprint mismatch | Better for high-energy surges but incompatible with space-constrained SOD123W layouts | Choose only if board redesign allows larger footprint and VRWM tolerance permits 45.1 V standoff |
Compared with SMAJ48A and 1.5SMC47A, the PTVS48VS1UTR,115 uniquely combines SOD123W miniaturization, 0.001 µA leakage, and 185 °C junction rating - making it optimal for thermally dense industrial and automotive-adjacent designs where size, leakage, and temperature margins are simultaneously constrained.

FAQ
What is the maximum clamping voltage of PTVS48VS1UTR,115 under standard IEC 61643-321 test conditions?
The clamping voltage VCL is 77.4 V at IPPM = 5.2 A for a 10/1000 µs current waveform, measured at Tj = 25 °C. This value remains stable across temperature due to the device's low 0.5 mV/K temperature coefficient, ensuring consistent protection margin in high-ambient environments.
Does PTVS48VS1UTR,115 support automated assembly processes like reflow soldering?
Yes - the SOD123W (CFP3) package is qualified for both lead-free reflow soldering (per JEDEC J-STD-020) and wave soldering. Nexperia provides validated footprints: 1.2 mm × 1.4 mm solder lands with 0.1 mm stencil thickness recommended for optimal wetting and void control.
How does the 0.001 µA reverse leakage impact system-level power budgeting?
At VRWM = 48 V, the maximum IRM of 0.001 µA contributes just 48 nW of static power loss - negligible in battery-powered or energy-harvesting nodes. This enables use in always-on sensor interfaces and backup power circuits where even nanoampere leakage would degrade runtime or accuracy.
Can PTVS48VS1UTR,115 replace older P6SMB48A devices in existing designs?
No - P6SMB48A uses DO-214AA (SMB) package (4.6 mm × 3.9 mm), while PTVS48VS1UTR,115 uses SOD123W (2.6 mm × 1.7 mm). Though VRWM and VCL are similar, the footprint, thermal resistance (18 K/W vs. ~50 K/W), and leakage (0.001 µA vs. 1 µA) differ significantly. Board redesign is required for drop-in replacement.
