Nexperia USA Inc. PMEG4015EPK-QYL

Overview

PMEG4015EPK-QYL from Nexperia is a 40 V, 1.5 A planar Schottky barrier rectifier with integrated guard ring for stress protection, housed in an ultra-small leadless DFN1608D-2 (SOD1608) package. It delivers low forward voltage (540–610 mV at 1.5 A), ultra-fast reverse recovery (<4 ns), and AEC-Q101 qualification-enabling use in automotive LED backlighting and high-efficiency DC-DC converters where space, thermal performance, and reliability are critical.

For engineers reviewing the PMEG4015EPK-QYL datasheet, PMEG4015EPK-QYL pinout, PMEG4015EPK-QYL application, or PMEG4015EPK-QYL equivalent, key selection criteria include its 0.37 mm profile, side-wettable flanks for automated optical inspection, 1.5 A average forward current rating at ≤65 °C ambient, and low reverse leakage (1–5 µA at 10 V).

Technical Context

This Schottky diode uses a planar junction structure with an integrated guard ring to suppress edge breakdown under high-voltage stress, enabling stable operation up to 40 V reverse bias. Its metal-semiconductor interface yields near-zero minority-carrier storage, eliminating reverse recovery charge and supporting ultra-high-speed switching.

The device is optimized for reflow-only assembly on FR4 or ceramic PCBs, with thermal resistance from junction to solder point as low as 20 K/W when mounted on a 1 cm² cathode pad. Its 0.94 mm pitch and visible side pads support AOI-compatible solder joint verification.

FAQ

Is PMEG4015EPK-QYL compatible with lead-free reflow processes?

Yes. The device is qualified for reflow soldering only, with peak temperature up to 260 °C per JEDEC J-STD-020. Its DFN1608D-2 package uses matte tin-plated side pads compatible with standard SAC305 paste and industry-standard reflow profiles. Hand soldering or wave soldering is not recommended.

What is the maximum continuous forward current at 105 °C ambient?

At Tamb = 105 °C on an FR4 PCB with standard footprint, the maximum average forward current is 0.95 A (δ = 0.5, f = 20 kHz square wave). This derating is defined in Figure 10 of the datasheet and accounts for thermal resistance and junction temperature limits (Tj ≤ 150 °C).

Does the cathode marking bar indicate polarity during PCB layout?

Yes. The marking bar on the top surface aligns with Pin 1 (cathode) in the DFN1608D-2 outline. During layout, the copper pour connected to Pin 1 must be designated as the cathode net, and the silkscreen bar must match the physical orientation shown in Figure 17 of the datasheet to prevent reverse installation.

Can PMEG4015EPK-QYL replace a standard silicon diode in a 24 V automotive circuit?

Yes, provided the original diode's VR ≥ 40 V and IF(AV) ≤ 1.5 A. The Schottky's lower VF reduces power loss by ~400 mW at 1.5 A versus a typical 1N4007, directly lowering thermal stress. However, its higher IR versus silicon requires verification in high-temperature reverse-bias conditions (>125 °C).
