Nexperia USA Inc. PMEG2005EL,315

Overview

PMEG2005EL,315 from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, rated for 20 V reverse voltage and 0.5 A continuous forward current, featuring ultra-low forward voltage (450–500 mV at 500 mA) in a leadless SOD882 package (1.0 × 0.6 × 0.5 mm). It serves as a high-efficiency rectifier in space-constrained DC-DC converters and low-voltage protection circuits.

For engineers reviewing the PMEG2005EL,315 datasheet, PMEG2005EL,315 pinout, PMEG2005EL,315 application, or PMEG2005EL,315 equivalent, key selection criteria include its 20 V VR rating, 0.5 A IF capability, sub-500 mV VF at rated current, 24–30 pF junction capacitance, and thermal resistance of 500 K/W - all critical for ultra-compact, low-loss power management designs.

Technical Context

This MEGA-series Schottky diode uses a planar structure with an integrated guard ring to enhance ruggedness against electrical overstress while maintaining low conduction loss. Its low VF stems from optimized metal-semiconductor interface design, enabling efficient operation at low forward currents (125–180 mV at 0.1 mA) and high currents (450–500 mV at 500 mA).

Thermal performance is defined under standard SOD882 mounting on FR4 with 60 μm copper; Rth(j-a) = 500 K/W in free air reflects its suitability for thermally unassisted, low-power applications. Reverse leakage remains tightly controlled (4–30 μA at 10 V), supporting stable clamping and protection functions across −65 °C to +150 °C ambient.

Key Specifications

Pinout & Package

FAQ

Is PMEG2005EL,315 suitable for automotive applications?

Yes. It is qualified per AEC-Q200 requirements with operating ambient temperature from −65 °C to +150 °C, integrated guard ring for ESD robustness, and stable reverse leakage up to 150 °C junction temperature - making it appropriate for under-hood sensor bias, infotainment power rails, and body control module protection circuits.

What is the recommended PCB layout for thermal performance?

Use the standard SOD882 footprint per Nexperia's outline drawing: 0.62 mm pad width, 0.55 mm pad length, 0.50 mm center-to-center pitch. Add ≥10 mm² of 60 μm copper pour connected to both terminals to reduce Rth(j-a) toward 300 K/W; avoid soldermask over thermal pads.

Does PMEG2005EL,315 have a specified reverse recovery time (trr)?

No trr value is specified because Schottky diodes are majority-carrier devices with no minority-carrier storage delay. Its effective switching speed is governed by junction capacitance (24–30 pF) and series resistance, enabling sub-nanosecond turn-off in clamping and high-frequency rectification.

How does the guard ring affect electrical performance?

The integrated guard ring increases edge termination robustness without altering forward conduction characteristics. It raises the device's ESD rating (HBM >8 kV) and improves resistance to localized avalanche during voltage transients - verified in Nexperia's stress testing - while maintaining the same VF, IR, and Cd as non-guarded variants.
