1N5819 B0G

Overview

The Taiwan Semiconductor 1N5819 B0G is a Schottky Barrier Rectifier in the DO-204AL (DO-41) package. It features a maximum repetitive peak reverse voltage of 40 V and an average forward current rating of 1 A. The device exhibits a typical forward voltage drop of 0.60 V at 1 A and supports a surge peak forward current of 30 A. Operating junction temperatures range from -55 °C to +125 °C, with a thermal resistance of 100 °C/W junction-to-ambient.

Feature Summary

• Guard ring construction provides overvoltage protection
• Low forward voltage drop for high efficiency
• High surge current capability

Applications

• Switching mode power supplies
• Adapters
• DC to DC converters

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging details and qualification status. Confirm RoHS compliance and halogen-free status requirements match project specifications. Ensure the component meets JESD 201 class 2 whisker test standards if applicable.

Selection Notes

Select this component for low-voltage, high-frequency rectification applications requiring fast switching speeds. Evaluate thermal management needs based on the specified junction-to-ambient thermal resistance. Consider the 30 A surge current rating for circuits experiencing transient load spikes.

Part Context

This part belongs to the 1N5817–1N5819 series of 1 A Schottky Barrier Rectifiers manufactured by Taiwan Semiconductor. The series covers voltage ratings from 20 V to 40 V within the same DO-204AL package form factor, allowing for design flexibility across different voltage requirements.

Replacement Considerations

Cross-reference with other manufacturers' 1N5819 equivalents ensuring identical DO-41 packaging and 40 V / 1 A ratings. Verify that substitute components meet the same electrical characteristics and physical dimensions for direct pin-compatible replacement.
