Nexperia USA Inc. PMEG040V050EPEZ

Overview

PMEG040V050EPE from Nexperia is a 40 V, 5 A planar low forward voltage Schottky barrier rectifier in a CFP15B (SOT1289B) thermally enhanced SMD package, designed for high-efficiency DC-to-DC conversion and freewheeling paths where low conduction loss and fast switching are critical. It delivers VF = 475–520 mV at 5 A and 25 °C, IR ≤ 120 µA at 40 V, and supports IF(AV) = 5 A with δ = 0.5 square-wave excitation.

For engineers reviewing the PMEG040V050EPE datasheet, PMEG040V050EPE pinout, PMEG040V050EPE application, or PMEG040V050EPE equivalent, key selection criteria include forward voltage optimization at high current, thermal resistance to solder point (Rth(j-sp) = 3 K/W), reverse recovery performance (trr ≤ 12 ns), and compatibility with ultra-thin PCB layouts requiring < 1 mm profile height.

Technical Context

This Schottky rectifier uses clip-bond technology to minimize parasitic resistance and enhance thermal transfer from junction to cathode tab. Its planar structure ensures stable reverse breakdown (V(BR)R ≥ 40 V) and low capacitance (Cd = 370 pF at VR = 1 V), enabling clean switching in high-frequency SMPS topologies.

The device operates across -55 °C to +175 °C junction temperature, with pulse-tested VF characteristics validated from -40 °C to +125 °C. Its step-recovery trr ≤ 12 ns and ramp-recovery trr ≤ 11 ns confirm minimal minority-carrier storage-critical for OR-ing and reverse polarity protection circuits demanding zero reverse conduction delay.

FAQ

What is the maximum allowable solder point temperature for PMEG040V050EPE during reflow?

The device supports peak reflow temperatures up to 260 °C for ≤ 30 seconds per J-STD-020, with recommended solder paste stencil thickness of 0.125 mm. The cathode tab must contact ≥1 cm² of 1 oz copper to maintain Tsp ≤ 172 °C under 5 A average current, as specified in Table 1 for IF(AV) derating.

Can PMEG040V050EPE replace a standard PN-junction rectifier in a 24 V input flyback design?

Yes - its 40 V VR rating and 120 A IFSM surge capability allow direct substitution in 24 V systems with transient margin. Unlike PN diodes, it exhibits no reverse recovery charge (Qrr ≈ 0), eliminating switching losses and EMI associated with tail current, provided layout minimizes cathode loop inductance.

How does the dual-anode (pins 1 and 2) configuration affect PCB layout?

Pins 1 and 2 are internally shorted anodes; both must be routed to the same net. This configuration halves effective series resistance versus single-pin anode devices, reducing voltage drop and localized heating. Thermal relief should be minimized on both pads to maximize current sharing and thermal conduction.

Is PMEG040V050EPE suitable for automotive applications?

No - this part is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or guaranteed PPAP documentation. Nexperia explicitly states non-automotive qualification in Section 15 of the datasheet; use only in industrial, computing, or consumer power supplies.
