Nexperia USA Inc. PNS40010ER,115

Overview

PNS40010ER from Nexperia is a 400 V, 1 A standard recovery rectifier diode in SOD123W (CFP3) surface-mount package, designed for high-power-density general-purpose rectification and reverse polarity protection. It features low forward voltage (0.91 V typ. at 0.7 A), low reverse leakage (0.001 µA typ. at 400 V/25 °C), 1.8 µs max reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability.

For engineers reviewing the PNS40010ER datasheet, PNS40010ER pinout, PNS40010ER application, or PNS40010ER equivalent, key selection criteria include its 400 V repetitive peak reverse voltage, 1 A average forward current capability on ceramic PCB, 0.8–1.8 µs reverse recovery time, thermal resistance of 65 K/W (junction-to-ceramic-PCB), and compatibility with reflow and wave soldering processes.

Technical Context

This standard recovery rectifier uses high-efficiency planar silicon technology to achieve stable switching behavior without soft-recovery optimization-suited for non-resonant, moderate-frequency (<100 kHz) rectification where EMI constraints are moderate. Its 1.8 µs trr enables use in flyback and boost converters operating up to 20 kHz square-wave duty cycling.

The device operates across –55 °C to +175 °C junction temperature, with thermal performance strongly dependent on PCB mounting: Rth(j-a) ranges from 200 K/W (FR4, standard footprint) to 65 K/W (Al₂O₃ ceramic, standard footprint). Cathode-tab solder point thermal resistance is 15 K/W, enabling effective heat extraction in space-constrained layouts.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The PNS40010ER has a maximum junction temperature (Tj) rating of 175 °C. Continuous operation at this limit requires strict thermal management-typically achieved using an Al₂O₃ ceramic PCB with ≥1 cm² cathode pad area to maintain Rth(j-a) ≤65 K/W. At ambient temperatures above 100 °C, derating to ≤0.7 A IF(AV) is required per Figure 12.

Can the PNS40010ER replace a Schottky diode in a 5 V output rectifier?

No-it is not a drop-in Schottky replacement due to higher VF (0.91 V vs. typical 0.4–0.55 V) and slower trr (0.8–1.8 µs vs. <0.1 µs). While it can function in low-frequency (<20 kHz) 5 V rectifiers, efficiency will be 8–12% lower than a Schottky, and EMI may increase. Use only where Schottky leakage or temperature instability is problematic.

Is the SOD123W package compatible with standard reflow profiles?

Yes-the PNS40010ER is qualified for lead-free reflow per J-STD-020, with peak solder temperature up to 260 °C and time above liquidus ≤60 s. Its flat-lead CFP3 construction ensures coplanarity and prevents tombstoning; recommended stencil aperture is 1.1 mm × 1.2 mm per pad (Fig. 17).

How does reverse leakage change at elevated temperature?

Reverse leakage rises exponentially with temperature: IR = 0.001 µA at 25 °C, 1 µA at 125 °C, and 500 µA at 175 °C (per Table 7). In high-temperature reverse-bias applications (e.g., >100 °C ambient), leakage-induced power loss (PR = VR × IR) must be calculated-e.g., 400 V × 1 µA = 0.4 mW at 125 °C, negligible for most designs.
