Nexperia USA Inc. PMEG2005ESFCYL

Overview

PMEG2005ESFCYL from Nexperia is a 20 V, 0.5 A low forward voltage Schottky barrier rectifier in a DSN0603-2 (SOD962-2) leadless chip-scale package, designed for ultra-compact DC-to-DC conversion and mobile LED backlighting. It delivers typ. VF = 310 mV at 10 mA, IR = 0.37 µA at 10 V, and trr = 1.9 ns - enabling high-efficiency, high-speed switching in space-constrained portable power rails.

For engineers reviewing the PMEG2005ESFCYL datasheet, PMEG2005ESFCYL pinout, PMEG2005ESFCYL application, or PMEG2005ESFCYL equivalent, key selection criteria include its 0.3 mm profile, cathode-marked 2-terminal CSP layout, thermal resistance of 40 K/W to solder point, and suitability for low-voltage synchronous rectification in buck converters below 20 V.

Technical Context

This MEGA Schottky diode uses a planar silicon structure with integrated guard ring for robust ESD and surge stress protection. Its ultra-low VF stems from optimized metal-semiconductor interface design, not edge termination or process scaling alone.

It operates as a unidirectional, two-terminal passive rectifier - no control logic, no bias circuitry, no internal capacitance tuning. Reverse recovery is inherently fast due to majority-carrier conduction, confirmed by trr = 1.9 ns under IF = IR = 500 mA conditions.

Key Specifications

Pinout & Package

DSN0603-2 (SOD962-2) is a 2-terminal, leadless chip-scale package measuring 0.6 × 0.3 × 0.3 mm with exposed anode/cathode pads and no molded body sidewalls. The marking bar identifies the cathode side.

FAQ

What is the maximum allowable solder point temperature for PMEG2005ESFCYL during reflow?

The absolute maximum solder point temperature is 145 °C for δ = 0.5 duty cycle at 20 kHz, per limiting values table. For standard lead-free reflow profiles, peak temperature must not exceed 140 °C at the solder joint to avoid degradation of the die attach and interconnect reliability. Thermal resistance to solder point is 40 K/W, so 140 °C corresponds to 660 mW dissipation limit.

Can PMEG2005ESFCYL be used in automotive applications?

No - PMEG2005ESFCYL is not AEC-Q200 qualified and lacks automotive-grade screening, high-temperature storage validation, or extended lifetime testing per automotive requirements. Nexperia explicitly states non-automotive qualification in the legal disclaimers, and the device is rated only for −55 °C to +150 °C junction temperature, not the full −40 °C to +125 °C ambient range required for under-hood use.

How does the guard ring affect layout requirements?

The integrated guard ring requires no special PCB layout - it functions internally to suppress edge breakdown. However, designers must maintain ≥0.15 mm clearance between the anode and cathode solder pads and any adjacent copper pour or trace to prevent solder bridging and ensure manufacturability in the 0.6 × 0.3 mm footprint. No guard ring trace or keep-out zone is needed beyond standard DSN0603-2 land pattern rules.

Is reverse recovery time (trr) measured under real-world switching conditions?

Yes - trr = 1.9 ns is measured under defined pulsed conditions: IF = IR = 500 mA, IR(meas) = 100 mA, Tj = 25 °C, using square-wave excitation. This reflects actual behavior in high-frequency buck converters, not idealized small-signal conditions. Data sheet Figure 13 confirms the measurement methodology aligns with JEDEC JESD24-10 standards for Schottky diodes.
