Nexperia USA Inc. PMEG2005AEL,315

Overview

PMEG2005AEL,315 from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, rated for 0.5 A forward current and 20 V reverse voltage, featuring ultra-low forward voltage (375–440 mV at 500 mA) in a leadless SOD882 package; used in high-efficiency DC-DC converters and low-voltage clamping circuits.

For engineers reviewing the PMEG2005AEL,315 datasheet, PMEG2005AEL,315 pinout, PMEG2005AEL,315 application, or PMEG2005AEL,315 equivalent, key selection criteria include forward voltage at 500 mA, reverse leakage at 20 V, junction-to-ambient thermal resistance, diode capacitance at 1 V, and SOD882 footprint compatibility with space-constrained PCB layouts.

Technical Context

This MEGA Schottky rectifier uses a planar silicon structure with an integrated guard ring to suppress edge breakdown under electrical stress, enabling stable operation up to 150 °C junction temperature. Its low VF stems from optimized metal-semiconductor interface design rather than barrier height reduction alone.

The device exhibits low reverse recovery charge (Qrr not specified but implied by Schottky architecture) and minimal stored charge, supporting ultra-high-speed switching (tRR < 10 ns typical). Diode capacitance remains below 25 pF at 1 V reverse bias, supporting RF-sensitive applications like EMI filtering in power rails.

FAQ

Is PMEG2005AEL,315 suitable for reverse polarity protection in 5 V battery-powered systems?

Yes. With a 20 V reverse voltage rating and 375–440 mV forward drop at 500 mA, it provides efficient series blocking while maintaining >92% voltage efficiency at full load. Its 150 °C junction rating supports operation in sealed enclosures where internal temperatures exceed 85 °C ambient.

How does the guard ring improve reliability compared to standard Schottky diodes?

The integrated guard ring redistributes electric field at the die periphery, suppressing edge-initiated avalanche under repetitive transient stress. This prevents parametric drift in IR and VF over time-critical in automotive and industrial protection circuits where failure modes must be predictable over 10+ years.

Can PMEG2005AEL,315 replace SOT23-packaged Schottky diodes without layout changes?

No. Though its power dissipation is comparable to SOT23, the SOD882 package has different pad geometry (1.0 × 0.6 mm vs. SOT23's 2.9 × 1.3 mm) and bottom-terminal construction. A dedicated footprint redesign is required to accommodate solder paste volume, reflow profile, and mechanical anchoring.

What is the maximum allowable PCB copper area for thermal performance in free-air conditions?

Per Nexperia's SOD882 standard mounting conditions, a 60 μm copper strip line (minimum 0.5 mm width) is sufficient to achieve the stated 500 K/W Rth(j-a). Adding thermal vias under the terminals improves performance, but is not required for 0.5 A continuous operation at Tamb ≤ 60 °C.
