Product details
Overview
PTVS48VP1UP,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 48 V reverse standoff voltage (VRWM), 58.9 V maximum breakdown voltage (VBR), 77.4 V clamping voltage (VCL) at 7.8 A peak pulse current (IPPM), and <0.1 µA reverse leakage at VRWM - deployed in industrial power supply protection circuits.
For engineers reviewing the PTVS48VP1UP,115 datasheet, PTVS48VP1UP,115 pinout, PTVS48VP1UP,115 application, or PTVS48VP1UP,115 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance to solder point (12 K/W), AEC-Q101 qualification status per revision history, and compatibility with FR4 PCB layouts using standard CFP5 reflow footprints.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device: it remains high-impedance below VRWM = 48 V, then avalanches sharply at VBR = 53.3–58.9 V to limit transients. Its IEC 61643-321-compliant 10/1000 µs waveform rating ensures robustness against lightning-induced surges and inductive switching spikes.
Thermal design is enabled by low Rth(j-sp) = 12 K/W to cathode solder point and Rth(j-a) = 60 K/W on ceramic PCB - critical for sustained surge handling in enclosed industrial enclosures. The SOD128 package's 1 mm height supports ultra-thin board stacking while maintaining 100 A non-repetitive forward surge capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W (IEC 61643-321, 10/1000 µs); sustains single high-energy surges without degradation |
| Reverse Standoff Voltage | VRWM = 48 V; maximum continuous DC operating voltage before leakage exceeds 0.1 µA |
| Clamping Voltage | VCL = 77.4 V at IPPM = 7.8 A; limits downstream IC voltage during surge to safe margin above 48 V rail |
| Breakdown Voltage | VBR = 53.3–58.9 V at IR = 1 mA; defines precise avalanche initiation threshold for predictable clamping onset |
| Reverse Leakage | IRM ≤ 0.1 µA at VRWM; negligible standby power loss and no measurable impact on 48 V system efficiency |
| Package Thermal Resistance | Rth(j-sp) = 12 K/W; enables direct heat transfer from junction to cathode solder joint for high-reliability mounting |
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., +48 V rail); carries full surge current during clamping |
| 2 | Anode (A) | Connected to ground reference; forms low-impedance path to divert transient energy away from load |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability (per revision v.3, includes PTVS48VP1UP); supports extended temperature range (-55 °C to +150 °C) |
| Low-profile SOD128 package | 1.0 mm max height enables use in space-constrained industrial controllers and telecom power modules |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2); protects against handling and system-level ESD events without external shielding |
| High surge current capability | IPPM = 7.8 A at VCL = 77.4 V; handles repetitive 10/1000 µs transients in 48 V PoE++ and industrial PLC inputs |
Applications
| Industrial Power Supply Protection | Telecom DC Power Input |
|---|---|
Use Scenario: 48 V DC input stage of programmable logic controller (PLC) exposed to field wiring surges. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between +48 V rail and chassis ground.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ48A | DO-214AC package; VRWM = 48 V, VCL = 77.4 V at 7.8 A, but Rth(j-a) = 75 K/W (vs. 60 K/W on ceramic) | Larger footprint (4.5 × 2.7 mm vs. 3.8 × 2.6 mm); less suitable for dense 48 V telecom modules | Prefer PTVS48VP1UP,115 where board space and thermal performance on ceramic substrates are critical. |
| SMCJ48A | DO-214AB package; same VRWM/VCL, but PPPM = 1500 W and IPPM = 19.8 A - significantly higher surge capacity | Requires larger PCB area (7.1 × 6.2 mm); used where multi-event surge immunity (e.g., outdoor substations) is mandatory | Choose PTVS48VP1UP,115 when 600 W rating suffices and miniaturization or AEC-Q101 compliance drives selection. |
Compared with SMAJ48A and SMCJ48A, PTVS48VP1UP,115 delivers identical clamping performance in a 30% smaller footprint with superior thermal resistance to solder point (12 K/W), making it optimal for thermally constrained 48 V industrial edge nodes where AEC-Q101 validation adds supply-chain assurance.

FAQ
What is the maximum clamping voltage of PTVS48VP1UP,115 under IEC 61643-321 test conditions?
The maximum clamping voltage (VCL) is 77.4 V at 7.8 A peak pulse current (IPPM), measured with a 10/1000 µs current waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range (−55 °C to +150 °C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is PTVS48VP1UP,115 qualified to AEC-Q101, and does that qualification apply to this specific part number?
Yes - according to the December 2025 revision history (v.3), PTVS48VP1UP is explicitly listed among the 25 products granted AEC-Q101 qualification. This applies directly to PTVS48VP1UP,115, confirming its suitability for automotive power systems including engine control units and body electronics where stress-test validation is required.
How does the SOD128 package affect PCB layout and thermal management?
The SOD128 (CFP5) package requires a reflow footprint with 2.5 mm × 3.4 mm solder lands and 1.9 mm × 2.1 mm solder paste openings per pad. Its 12 K/W junction-to-solder-point thermal resistance demands direct copper connection to cathode pad and ≥1 cm² thermal relief on FR4 or ceramic PCBs to sustain repeated 600 W pulses without junction overheating.
Can PTVS48VP1UP,115 be used in bidirectional configurations?
No - PTVS48VP1UP,115 is a unidirectional TVS diode with anode and cathode terminals. It conducts only during reverse-biased overvoltage events. For bidirectional protection, two devices must be connected in series opposition, or a dedicated bidirectional TVS (e.g., PTVS48VU1UP) should be selected instead.
