Nexperia USA Inc. PMEG3005ESFCYL

Overview

PMEG3005ESFCYL from Nexperia is a 30 V, 0.5 A low forward-voltage Schottky barrier rectifier in a DSN0603-2 (SOD962-2) leadless chip-scale package. It delivers typ. VF = 310 mV at 10 mA and typ. IR = 0.33 µA at 30 V, with 0.3 mm profile height, optimized for ultra-thin mobile power conversion and LED backlighting.

For engineers reviewing the PMEG3005ESFCYL datasheet, PMEG3005ESFCYL pinout, PMEG3005ESFCYL application, or PMEG3005ESFCYL equivalent, key selection criteria include low VF under light-load DC-DC conditions, sub-1 ns reverse recovery time, thermal resistance to solder point (Rth(j-sp) = 40 K/W), and compatibility with high-density PCB layouts requiring <0.6 mm × 0.3 mm footprints.

Technical Context

This MEGA Schottky rectifier uses a planar silicon structure with integrated guard ring for enhanced ESD and surge robustness. Its ultra-low VF enables higher efficiency in 1–5 V output rails, while trr = 1.42 ns supports switching frequencies beyond 10 MHz in synchronous buck converters.

The device operates across −40 °C to +150 °C junction temperature, with thermal performance dependent on PCB mounting: Rth(j-a) ranges from 105 K/W (ceramic PCB) to 310 K/W (standard FR4), and maximum average forward current drops from 0.5 A at Tsp ≤ 145 °C to 0.2 A at Tamb = 105 °C on standard FR4.

FAQ

What is the maximum allowable solder point temperature for PMEG3005ESFCYL during reflow?

The absolute maximum solder point temperature is 150 °C, with recommended peak reflow temperature of 260 °C for ≤30 seconds per JEDEC J-STD-020. Exceeding 150 °C at the solder point risks permanent degradation of forward voltage and leakage characteristics due to interfacial diffusion in the CSP structure.

Can PMEG3005ESFCYL be used in reverse polarity protection circuits?

Yes-it functions as a low-loss series diode when anode is connected to input and cathode to load. With VF = 310 mV at 10 mA and IR = 0.33 µA at 5 V, it adds negligible dropout and standby drain, making it ideal for protecting 1.8–5 V rails in battery-backed systems where space and efficiency are critical.

How does the guard ring affect layout requirements on FR4 PCBs?

The integrated guard ring eliminates need for isolation trenches or increased keep-out zones around the die. Standard 0.256 mm solder land width (per Fig. 16) and 0.2 mm spacing to adjacent traces are sufficient-no additional clearance beyond IPC-2221 Class B guidelines is required for ESD or voltage hold-off.

Is thermal derating required when using only one 0.2 mm × 0.6 mm pad instead of the full 1 cm² anode/cathode pad?

Yes-reducing pad area to 0.12 cm² (typical for DSN0603-2 footprint) increases Rth(j-a) to ~250 K/W. At Tamb = 60 °C, IF(AV) must be limited to 0.22 A to maintain Tj ≤ 125 °C, per Fig. 9. Full 1 cm² pads are required to achieve the rated 0.5 A average current.
