Nexperia USA Inc. PMEG3002AELD-QYL

Overview

PMEG3002AELD-QYL from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage, high-efficiency DC-to-DC conversion and reverse polarity protection in space-constrained automotive electronics. It delivers 0.2 A average forward current at ≤480 mV forward voltage (IF = 200 mA), supports 30 V reverse voltage, operates up to 150 °C junction temperature, and is qualified to AEC-Q101.

For engineers reviewing the PMEG3002AELD-QYL datasheet, PMEG3002AELD-QYL pinout, PMEG3002AELD-QYL application, or PMEG3002AELD-QYL equivalent, key selection criteria include ultra-low VF for efficiency-critical 3.3 V/5 V rail rectification, SOD882D side-wettable flanks for automated optical inspection (AOI), and thermal performance on FR4 with 1 cm² cathode pad.

Technical Context

This Schottky diode uses a planar die structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low 430–480 mV VF at 200 mA enables minimal conduction loss in compact power stages.

Thermal design relies on junction-to-solder-point resistance of 50 K/W (cathode tab) and junction-to-ambient of 125 K/W on ceramic PCB - critical for sustained 0.2 A operation in sealed automotive modules where airflow is absent.

Key Specifications

FAQ

Is PMEG3002AELD-QYL compatible with lead-free reflow profiles?

Yes. The SOD882D package is qualified for standard IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C. Reflow must follow Nexperia's recommended footprint (1.4 mm × 0.8 mm with dual 0.6 mm side pads) and thermal profile to ensure void-free solder joints on side-wettable flanks.

What is the maximum allowable ambient temperature for continuous 0.2 A operation on FR4 PCB?

On standard FR4 with single-sided 1 cm² cathode copper, the maximum ambient temperature is 105 °C at δ = 0.5, 20 kHz (per Figure 10). At 25 °C ambient, full 0.2 A is sustainable; above 105 °C, derating is required to maintain Tj ≤ 150 °C.

Does the guard ring affect electrical parameters like VF or IR?

No. The guard ring is a structural feature surrounding the active junction to prevent premature edge breakdown under high electric fields. It does not alter forward conduction characteristics (VF, IF) or reverse leakage (IR); those remain defined solely by the planar Schottky junction design.

Can PMEG3002AELD-QYL replace a standard 1N5817 in existing designs?

Only with layout revision. While both are 30 V/1 A Schottkys, PMEG3002AELD-QYL uses SOD882D (1.0 mm × 0.6 mm), whereas 1N5817 uses DO-204AL (4.3 mm × 2.6 mm). Direct replacement requires footprint redesign, but the smaller size and lower VF justify the change in new automotive or portable designs.
