MBR0520LT1G Schottky Diode Specifications Applications and Suppliers

ElecSuppliers Part Number GuideAug 15, 2026

MBR0520LT1G is a Schottky diode from onsemi designed for low voltage rectification and switching applications. The component combines a low forward voltage characteristic with fast switching behavior, making it useful in circuits where reducing conduction losses is important.

The complete part number is particularly relevant when sourcing the device because the MBR0520 family includes related diode products with different electrical and packaging configurations.

What Is MBR0520LT1G

MBR0520LT1G is a low voltage Schottky rectifier. Its 20 V reverse voltage rating makes it suitable for applications operating at relatively low supply voltages where the diode needs to provide rectification or current path control.

Schottky diodes are different from conventional PN junction rectifiers because they use a metal semiconductor junction. This structure generally provides a lower forward voltage and very fast switching response.

These characteristics are useful in power management circuits where every fraction of a volt can affect efficiency.

MBR0520LT1G Electrical Characteristics

The most important parameters to check when selecting MBR0520LT1G include reverse voltage, forward current, forward voltage, reverse leakage current and power dissipation.

The low forward voltage of a Schottky diode can help reduce the voltage drop across the device when it is conducting. This can be particularly valuable in low voltage power circuits.

However, Schottky devices can have higher reverse leakage than conventional silicon diodes. Engineers should therefore evaluate both forward conduction and reverse leakage under the expected operating temperature and voltage conditions.

MBR0520LT1G Applications

MBR0520LT1G can be used in low voltage power circuits where efficient rectification or fast current switching is required.

Possible applications include DC power supplies, battery powered equipment, polarity protection, power management circuits and compact electronic devices.

It can also be useful as a catch or freewheeling diode in suitable switching circuits where the voltage and current requirements remain within the device ratings.

Why the 20V Rating Matters

The 20 V rating is an important part of selecting MBR0520LT1G.

The reverse voltage appearing across the diode during normal operation and transient conditions should remain within the specified limit. A circuit that normally operates below 20 V may still produce short voltage spikes that need to be considered during component selection.

For this reason, engineers should evaluate the complete operating environment rather than selecting the diode based only on its nominal supply voltage.

MBR0520LT1G Package

MBR0520LT1G is intended for compact surface mount electronic designs. Its package allows the diode to be integrated into PCB assemblies without requiring a larger through hole component.

When designing the board or replacing an existing diode, the package dimensions, pin configuration and recommended PCB footprint should be verified.

A different Schottky diode with similar electrical ratings may not be a mechanical replacement if its package or terminal arrangement differs.

MBR0520LT1G Supplier Information

When searching for MBR0520LT1G suppliers, using the complete manufacturer part number is the most reliable way to identify the required component.

Buyers should confirm the manufacturer, reverse voltage rating, forward current, package, product status and available quantity before purchasing.

For production applications, it is also important to distinguish MBR0520LT1G from other low voltage Schottky diodes that may have similar specifications but different ordering codes.
