Nexperia USA Inc. PMEG2015EJ,115

Overview

PMEG2015EJ,115 from Nexperia is a single Schottky barrier rectifier in SOD323F (SC-90) package, rated for 20 V reverse voltage and 1.5 A forward current, featuring a typical forward voltage of 560 mV at 1.5 A. It delivers very low VF for high-efficiency DC-to-DC conversion and inverse polarity protection in space-constrained portable electronics.

For engineers reviewing the PMEG2015EJ,115 datasheet, PMEG2015EJ,115 pinout, PMEG2015EJ,115 application, or PMEG2015EJ,115 equivalent, key selection criteria include its 55 K/W junction-to-solder-point thermal resistance, 40–50 pF diode capacitance at 1 V, and cathode-marked SOD323F footprint compatibility with reflow-only assembly.

Technical Context

This discrete Schottky diode uses a planar MEGA structure with integrated guard ring for enhanced ESD and surge robustness. Its low VF stems from optimized metal-semiconductor interface and thin epitaxial layer design, enabling operation up to 150 °C junction temperature.

Thermal performance is defined for FR4 PCB mounting: R_th(j-a) = 350 K/W (standard footprint) or 150 K/W (1 cm² cathode pad), and R_th(j-sp) = 55 K/W - critical for thermal run-away mitigation in high-density power rails.

FAQ

Is PMEG2015EJ,115 suitable for reflow-only assembly?

Yes - Nexperia explicitly specifies reflow soldering as the only recommended method. The SOD323F package is qualified per J-STD-020, with peak reflow temperature up to 260 °C. Wave soldering is prohibited due to thermal stress risks and potential delamination.

What is the maximum ambient temperature for continuous 1.5 A operation?

Continuous 1.5 A operation is rated at T_sp ≤ 55 °C (solder point temperature), not ambient. On a standard FR4 PCB, ambient must be limited to ~45 °C to maintain T_sp ≤ 55 °C given R_th(j-sp) = 55 K/W and P_tot ≈ 840 mW at 1.5 A.

Does PMEG2015EJ,115 have built-in ESD protection?

Yes - its integrated guard ring structure provides inherent ESD robustness, achieving >8 kV HBM per JEDEC JS-001 and >15 kV IEC 61000-4-2 contact discharge, eliminating need for external TVS in most portable interface applications.

How does its 55 K/W R_th(j-sp) compare to similar SOD-123 Schottkys?

PMEG2015EJ,115's 55 K/W R_th(j-sp) is 20% lower than typical SOD-123 Schottkys (~65–70 K/W), due to optimized cathode pad geometry and thinner mold compound - enabling higher current density in thermally constrained 2-layer PCB designs.
