Nexperia USA Inc. PMEG4010EPK,315

Overview

PMEG4010EPK from Nexperia is a 40 V, 1 A low forward-voltage Schottky barrier rectifier in an ultra-small DFN1608D-2 (SOD1608) package, featuring integrated guard ring stress protection and solderable side pads. It delivers VF ≤ 600 mV at 1 A, IR ≤ 4 µA at 40 V, and trr ≤ 3 ns - optimized for high-efficiency DC-DC conversion and reverse polarity protection in space-constrained mobile power rails.

For engineers reviewing the PMEG4010EPK datasheet, PMEG4010EPK pinout, PMEG4010EPK application, or PMEG4010EPK equivalent, this device is selected for low-loss rectification in battery-powered systems where thermal performance, ultra-thin profile (0.37 mm height), and AEC-Q101 qualification for automotive-grade reliability are critical design requirements.

Technical Context

This MEGA Schottky rectifier uses a planar silicon structure with an integrated guard ring to suppress edge breakdown under high dv/dt or surge stress, enabling stable operation up to 150 °C junction temperature. Its low capacitance (Cd = 20–25 pF at VR = 10 V) and nanosecond-scale reverse recovery support ultra-high-speed switching in synchronous buck converters.

The device operates within strict thermal limits: Rth(j-sp) = 20 K/W (cathode tab), and Ptot = 1565 mW on ceramic PCB. Its average forward current rating of 1 A is validated under square-wave conditions (δ = 0.5, f = 20 kHz) with Tsp ≤ 135 °C - confirming suitability for continuous-duty, thermally demanding portable power stages.

FAQ

What is the maximum allowable solder point temperature for PMEG4010EPK during reflow?

The datasheet specifies Tsp ≤ 135 °C for δ = 0.5 square-wave operation and IF(AV) = 1 A. Reflow peak temperature must not exceed 260 °C for ≤ 30 seconds per JEDEC J-STD-020, with thermal profile validated for DFN1608D-2 footprint. Exceeding 135 °C at the cathode solder point risks permanent degradation of forward current rating.

Can PMEG4010EPK be used in place of a standard PN junction diode in a 12 V automotive circuit?

Yes - its 40 V VR rating and AEC-Q101 qualification make it suitable for 12 V automotive systems. However, unlike PN diodes, it has no minority-carrier storage delay, so it eliminates reverse recovery loss but requires attention to its higher reverse leakage (up to 20 µA at 40 V) in ultra-low-power sleep modes.

Does the cathode marking bar indicate polarity during PCB layout?

Yes - the marking bar on the top surface aligns with Pin 1 (cathode), as confirmed in Table 2 and Figure 17. This orientation must be matched to the silkscreen polarity indicator on the PCB to ensure correct forward conduction; reversed placement causes open-circuit behavior in rectifier configurations.

How does the DFN1608D-2 package affect thermal performance compared to SOD-123?

DFN1608D-2 achieves Rth(j-sp) = 20 K/W via direct cathode-tab conduction, outperforming SOD-123's typical Rth(j-a) > 100 K/W. However, its thermal path depends entirely on PCB copper area under the cathode pad - insufficient copper pour degrades performance more severely than in larger packages.
