Product details
Overview
PTVS48VP1UTP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection in automotive power rails. It features VRWM = 48 V, VBR(min) = 53.3 V at IR = 1 mA, VCL = 77.4 V at IPPM = 7.8 A (10/1000 µs), and operates up to Tj = 185 °C.
For engineers reviewing the PTVS48VP1UTP-QX datasheet, PTVS48VP1UTP-QX pinout, PTVS48VP1UTP-QX application, or PTVS48VP1UTP-QX equivalent, this device is selected for robust clamping in 48 V automotive subsystems where AEC-Q101 qualification, low leakage (<0.001 µA), and thermal stability are critical design requirements.
Technical Context
This TVS diode uses a planar silicon junction structure optimized for fast response (<1 ns) to ESD and surge transients per IEC 61000-4-2 (30 kV contact/air) and IEC 61643-321 (10/1000 µs waveform). Its unidirectional configuration provides forward conduction only during reverse overvoltage events, with clamping initiated at breakdown voltage ≥53.3 V.
Thermal design is enabled by Rth(j-sp) = 12 K/W to solder point and Rth(j-a) = 60 K/W on ceramic PCB, supporting sustained operation at ambient temperatures up to +185 °C. The cathode-marked SOD128 package ensures correct polarity placement in high-density automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W (IEC 61643-321, 10/1000 µs); sustains single-event surges without degradation |
| Reverse Standoff Voltage | VRWM = 48 V; maximum continuous DC or RMS voltage before clamping initiates |
| Breakdown Voltage | VBR(min) = 53.3 V at IR = 1 mA; guaranteed minimum clamping onset threshold |
| Clamping Voltage | VCL = 77.4 V at IPPM = 7.8 A; limits downstream IC voltage stress during surge |

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-Q | Lower PPPM = 400 W; VRWM = 48 V; VCL = 77.4 V; not AEC-Q101 qualified | Limited to industrial or non-safety-critical automotive subsystems | Select when cost sensitivity outweighs AEC-Q101 requirement and surge energy is <400 W |
| SMCJ48A-Q | Higher PPPM = 1500 W; same VRWM/VCL; larger DO-214AB package (7.11 mm × 6.22 mm) | Requires more PCB area; better suited for higher-energy load dump scenarios | Choose for systems requiring >600 W surge margin or legacy footprint compatibility |
Compared with SMAJ48A-Q, PTVS48VP1UTP-QX delivers certified automotive reliability and identical clamping performance in half the footprint; versus SMCJ48A-Q, it trades surge headroom for space-constrained placement in modern 48 V ECUs without sacrificing thermal capability.

FAQ
What is the maximum clamping voltage of PTVS48VP1UTP-QX at rated peak pulse current?
The clamping voltage VCL is 77.4 V at IPPM = 7.8 A under 10/1000 µs waveform conditions. This value is measured at Tj = 25 °C and guarantees that downstream circuitry sees no more than 77.4 V during a full 600 W transient event, enabling safe interface with 80 V-rated power management ICs.
Is PTVS48VP1UTP-QX suitable for bidirectional signal line protection?
No - PTVS48VP1UTP-QX is a unidirectional TVS diode intended only for DC power rail protection. Its anode-to-cathode forward voltage (~0.85 V) and lack of symmetrical breakdown make it unsuitable for AC or bidirectional data lines. For such applications, Nexperia's PTVS3V3S1UR−Q or similar bidirectional variants must be used.
How does the 185 °C junction temperature rating impact PCB layout?
The 185 °C Tj(max) rating allows uninterrupted operation at ambient temperatures up to 185 °C when mounted on ceramic substrates (Rth(j-a) = 60 K/W) or with direct thermal vias to inner ground planes. Layout must provide ≥1 cm² copper pour on cathode pad and avoid thermal isolation to maintain Rth(j-sp) ≤ 12 K/W.
Does the marking code 'D2' correspond exclusively to PTVS48VP1UTP-QX?
Yes - per Nexperia's official marking table, 'D2' is the unique top-side laser marking for PTVS48VP1UTP-QX. This code appears adjacent to the cathode bar on the SOD128 package and is verified in Table 4 of the product data sheet dated 17 November 2025.
