RB521S-30FVTE61

Single Diodes Overview

The RB521S-30FVTE61 is a silicon epitaxial planar Schottky barrier diode designed for low current rectification and high-speed switching applications. It features an extremely small surface-mount EMD2 package (SOD-523) while maintaining a guaranteed mean rectifying forward current of 200 mA. The device offers a typical forward voltage of 0.40 V at 200 mA, with a maximum rating of 0.50 V under the same conditions. It supports a DC reverse voltage of 30 V and a peak forward surge current of 1 A. The junction temperature range extends up to 125 °C, ensuring reliable operation in compact electronic circuits.

Single Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tape-and-reel quantity and lead-free specifications. Confirm the component meets sensitive product handling requirements during storage and assembly. Ensure the supplier provides documentation confirming compliance with RoHS directives and halogen-free standards where applicable.

Single Diodes Selection Notes

Select this component when space constraints require an SOD-523 footprint but standard diodes cannot support the necessary 200 mA current load. The low forward voltage characteristic makes it suitable for efficiency-critical low-voltage power paths. Verify thermal derating curves against the expected ambient operating temperature to ensure the junction temperature remains within safe limits.

Single Diodes Part Context
