PMEG4030ER,115

The PMEG4030ER,115 from Nexperia is a planar Schottky barrier rectifier in a SOD123W surface-mount package. It belongs to the PMEG series of Schottky diodes known for their:

• High efficiency: Low forward voltage drop, minimizing power dissipation.
• Fast switching speeds: Suitable for high-frequency applications.
• Compact size: Ideal for space-constrained designs.
• Ruggedness: Protected by an integrated guard ring for enhanced surge protection.

Here's a breakdown of the specific features of PMEG4030ER,115:

Specifications:

• Reverse voltage (VR): 40 V (maximum voltage the diode can withstand before breaking down)
• Average forward current (IF(AV)): 3 A (average current the diode can handle continuously)
• Forward voltage (VF): 540 mV (typical voltage drop at 3 A)
• Reverse leakage current (IR): 1 µA (typical leakage current when the diode is reverse-biased)
• Package: SOD123W (small, flat-lead surface-mount package)
• Operating temperature range: -55°C to +150°C
• RoHS and REACH compliant: Meets environmental regulations for lead-free and restricted substances

Applications:

• Rectification: Converting AC to DC in power supplies, chargers, and adapters.
• Freewheeling diode: Protecting circuits from inductive voltage spikes in motors and relays.
• Polarity protection: Preventing damage from incorrect voltage connection.
• General-purpose high-speed switching: Protecting circuits in various electronic devices.
