Frequently Asked Questions

What are the voltage rating and forward voltage drop specifications for PMEG4020EP in boost converter applications?

The PMEG4020EP features 40V reverse voltage rating with 0.49V typical forward voltage drop at 2A. In a 12V boost converter delivering 2A output, the 0.49V forward drop dissipates 980mW, compared to 1.4W for a 0.7V silicon diode, saving 420mW and enabling 4.3% higher converter efficiency at full load.

How does the PMEG4020EP's SOD-128 package compare to larger packages for modern compact power supply designs?

The PMEG4020EP's SOD-128 package measures 4.85mm x 2.15mm with single 0.8mm lead pitch, providing 50% area reduction compared to larger DO-214AB packages. This compact footprint enables 12mm x 12mm offline USB-PD adapter reference designs with multiple PMEG4020EP diodes for parallel redundancy.

When should PMEG4020EP replace 1N4148 general-purpose silicon diodes in switching power circuits?

The PMEG4020EP at 40V/2A with 0.49V forward drop outperforms 1N4148 (75V/0.15A) in any application requiring continuous current above 500mA at reduced voltage loss. A 5V to 12V boost stage using PMEG4020EP instead of 1N4148 delivers 3-5W higher output power at identical 3x3cm PCB area, making it essential for USB-C power delivery.
