Product details
Overview
PTVS48VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 48 V nominal systems. It features VRWM = 48 V, VBR(min) = 53.3 V, VCL(max) = 77.4 V at IPPM = 7.8 A (10/1000 µs), and IRM ≤ 0.001 µA - enabling robust ESD and surge suppression in 12–48 V power rails.
For engineers reviewing the PTVS48VP1UP-QX datasheet, PTVS48VP1UP-QX pinout, PTVS48VP1UP-QX application, or PTVS48VP1UP-QX equivalent, key selection criteria include clamping voltage margin vs. system rail, AEC-Q101 qualification status, thermal resistance to solder point (Rth(j-sp) = 12 K/W), and low-profile 1 mm height for space-constrained automotive PCB layouts.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: under transient overvoltage exceeding VRWM (48 V), it avalanches at VBR (53.3–58.9 V) and clamps the line to ≤77.4 V while diverting up to 7.8 A peak pulse current (IPPM). Its junction-to-solder-point thermal resistance of 12 K/W supports reliable power dissipation during repetitive transients when mounted per recommended footprint.
Qualified to AEC-Q101, it withstands 30 kV contact/air ESD (IEC 61000-4-2), 8 kV HBM, and non-repetitive 100 A forward surge (IFSM, 8.3 ms half-sine). The SOD128 package's cathode-marked lead configuration ensures correct polarity alignment in DC-biased protection paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - sustains IEC 61643-321 10/1000 µs surges without degradation |
| Reverse Standoff Voltage (VRWM) | 48 V - maximum continuous DC operating voltage before leakage rises significantly |
| Breakdown Voltage (VBR) | 53.3–58.9 V - guaranteed avalanche onset range at 1 mA test current |
| Clamping Voltage (VCL) | 77.4 V max at IPPM = 7.8 A - limits protected circuit voltage during worst-case surge |
| Reverse Leakage (IRM) | ≤0.001 µA at VRWM - negligible standby power loss in battery-sensitive systems |
| ESD Rating | 30 kV contact/air (IEC 61000-4-2) - exceeds automotive infotainment and sensor interface requirements |
| Junction Temp Limit (Tj) | 150 °C - enables operation in under-hood environments with localized heating |
Pinout & Package
SOD128 (CFP5) surface-mount plastic package: 2-terminal, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm pitch, flat lead profile optimized for automated assembly and thermal relief. Cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 48 V rail); avalanche conduction occurs from anode to cathode during overvoltage |
| 2 (A) | Anode | Typically tied to ground or low-impedance return path; defines unidirectional conduction direction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including engine control, ADAS, and body electronics |
| 1 mm package height | Enables placement beneath connectors or in tight board-to-board spacing |
| Low Rth(j-sp) = 12 K/W | Supports rapid heat transfer to PCB copper, improving surge endurance in repeated events |
| 0.001 µA IRM at VRWM | Minimizes quiescent current drain in always-on 48 V subsystems (e.g., domain controllers) |
| 30 kV ESD immunity | Eliminates need for additional ESD stages in CAN FD, LIN, or sensor front-ends |
Applications
| Automotive 48 V Power Distribution | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting 48 V DC-DC converter inputs against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed between input rail and chassis ground. Use Value: Clamps transients to ≤77.4 V within nanoseconds, preserving downstream MOSFET gate drivers and controller ICs. |
Use Scenario: Safeguarding analog input channels (e.g., 4–20 mA loops) from field-wiring induced surges. IC Role / Device Role / Timing Role: Primary overvoltage barrier ahead of precision op-amps and ADC front-ends. Use Value: Sub-µA leakage avoids signal offset errors; 77.4 V clamping prevents saturation of 24 V-rated signal chains. |
| Automotive Infotainment USB-C PD Lines | Server PSU 48 V Backplane Protection |
Use Scenario: Guarding USB-C power delivery lines in head units exposed to hot-plug and cable discharge events. IC Role / Device Role / Timing Role: Fast-response TVS on VBUS line, placed adjacent to connector. Use Value: 30 kV ESD rating meets USB-IF compliance; 1 mm height allows co-location with USB-C receptacle. |
Use Scenario: Mitigating cross-talk-induced spikes on 48 V server backplanes during hot-swap of compute modules. IC Role / Device Role / Timing Role: Distributed clamping device on each slot's power plane, near edge connector. Use Value: 600 W PPPM handles multi-module simultaneous insertion energy; AEC-Q101 ensures long-term reliability in datacenter thermal cycling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ48A-Q | Lower PPPM (400 W), higher VCL (80.0 V @ 7.5 A), same SOD-123 package | Limited to lower-energy transients; less margin for ISO 16750-2 Pulse 5a | Select when cost sensitivity outweighs peak surge headroom and board space permits larger footprint |
| TPSMD48CA | Bidirectional configuration (±48 V), same 600 W rating, DO-214AB package (4.5 mm height) | Protects AC-coupled or floating lines; unsuitable for polarized DC rails without redesign | Choose only if bidirectional threat model applies (e.g., differential bus lines); avoid for dedicated 48 V DC rails |
Compared with SMAJ48A-Q and TPSMD48CA, PTVS48VP1UP-QX delivers superior clamping performance (77.4 V vs. 80.0 V) in a lower-profile package (1.0 mm vs. 2.3 mm), making it optimal for modern automotive 48 V ECUs where height and surge margin are critical constraints.

FAQ
What is the maximum clamping voltage of PTVS48VP1UP-QX under rated surge conditions?
The maximum clamping voltage (VCL) is 77.4 V at IPPM = 7.8 A, measured using the IEC 61643-321 10/1000 µs waveform. This value is guaranteed across temperature and process variation, ensuring consistent protection margin for 48 V systems even under worst-case junction heating.
Is PTVS48VP1UP-QX suitable for bidirectional signal line protection?
No - it is a unidirectional TVS diode with cathode/anode polarity. Applying reverse bias beyond VRWM will cause high leakage or breakdown. For bidirectional protection (e.g., RS-485, CAN), a symmetric device like PTVS48VS1UP-QX or a dual-diode array must be used instead.
How does the SOD128 package affect thermal performance compared to SMA or DO-214AC?
The SOD128's 12 K/W junction-to-solder-point thermal resistance is ~3× better than standard SMA packages (~35 K/W). Its flat leads and large cathode pad enable direct thermal coupling to PCB copper, significantly improving sustained surge handling versus taller, leadframe-based alternatives.
Does PTVS48VP1UP-QX require derating at elevated ambient temperatures?
Yes - its rated peak pulse power decreases linearly above 25 °C ambient, with PPPM dropping to ~50% at 125 °C (per Fig. 2). Designers must apply junction temperature-aware derating using Rth(j-a) = 200 K/W (FR4, single-sided) or Rth(j-sp) = 12 K/W (cathode pad) to ensure safe operation in under-hood environments.
