Nexperia USA Inc. PMEG4010ESBYL

Overview

PMEG4010ESBYL from Nexperia is a 40 V, 1 A planar MEGA Schottky barrier rectifier in an ultra-small DSN1006-2 (SOD993) package, designed for low-voltage, high-efficiency DC-to-DC conversion and mobile LED backlighting. It delivers a typical forward voltage of 510 mV at 1 A and reverse current of 13 µA at 40 V, with a package height of only 270 µm.

For engineers reviewing the PMEG4010ESBYL datasheet, PMEG4010ESBYL pinout, PMEG4010ESBYL application, or PMEG4010ESBYL equivalent, key selection criteria include ultra-low VF for power loss reduction, sub-3 ns reverse recovery time for high-frequency switching, thermal performance on FR4 PCBs, and compatibility with space-constrained portable designs.

Technical Context

This Schottky diode uses a planar MEGA structure with integrated guard ring for robust stress protection under repetitive surge conditions. Its metal-semiconductor junction enables near-zero minority-carrier storage, resulting in trr < 3 ns and negligible reverse recovery charge.

The device operates with junction temperatures up to 150 °C and supports average forward currents up to 1 A under square-wave conditions (δ = 0.5, f = 20 kHz) on standard FR4 PCBs. Thermal resistance from junction to solder point is 15 K/W, enabling efficient heat extraction through anode/cathode pads.

FAQ

What is the maximum allowable soldering temperature profile for PMEG4010ESBYL?

The DSN1006-2 package is qualified for standard lead-free reflow per JEDEC J-STD-020. Peak temperature must not exceed 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s and ramp-down rate ≤6 °C/s. Preheat (150–200 °C) duration should be 60–120 seconds to avoid thermal shock to the die attach.

Can PMEG4010ESBYL replace a standard 1N5819 in a 5 V buck converter?

Yes, but only if the input voltage remains ≤40 V and layout accommodates the DSN1006-2 footprint. Unlike the axial 1N5819, PMEG4010ESBYL offers 510 mV VF (vs. ~450 mV at 1 A for 1N5819), but its 2.9 ns trr provides superior high-frequency behavior and eliminates reverse recovery losses absent in the older part.

How does the guard ring affect reliability in automotive infotainment power supplies?

The integrated guard ring improves ruggedness against voltage transients and ESD events common in 12 V automotive environments. While PMEG4010ESBYL is not AEC-Q200 qualified, its guard ring structure demonstrably increases failure threshold in load-dump simulations-making it viable for non-safety-critical infotainment subsystems with external clamping.

Is thermal derating required when mounting on 1 oz copper without extended pads?

Yes. On standard 1 oz FR4 with no thermal pads, Rth(j-a) rises to 240 K/W. At 1 A and 510 mV VF, power dissipation is 510 mW, causing ΔT = 122 °C - exceeding safe junction limits. Use ≥1 cm² copper pads per terminal or limit IF(AV) to ≤0.4 A for ambient ≤60 °C.
