FDLL4151

Single Diodes Overview

The FDLL4151 is a general-purpose small signal diode manufactured by Fairchild Semiconductor. It features a standard polarity and is housed in a DO-213AC (MINI-MELF, SOD-80) surface mount package. The device supports an operating junction temperature range of -65°C to 200°C. Key electrical specifications include a reverse voltage rating of 75V and a forward current capacity of 200mA. The typical forward voltage drop is 1V. This component combines high forward conductance with fast switching speed and high blocking voltages in a glass leadless package.

Single Diodes Procurement Notes

Verify the specific revision status of the datasheet, as documentation indicates this product may be discontinued or obsolete by Fairchild Semiconductor. Confirm availability through authorized distributors or secondary market suppliers. Ensure that the received components match the DO-213AC/SOD-80 package dimensions and electrical ratings specified in the official Fairchild documentation before integration into production designs.

Single Diodes Selection Notes

Select the FDLL4151 for applications requiring a surface-mount general-purpose diode with robust thermal performance. The SOD-80 package offers a compact footprint suitable for space-constrained designs. Consider the 75V reverse voltage and 200mA forward current limits when designing circuit protection or signal routing paths. Verify compatibility with automated assembly processes due to the MINI-MELF form factor.

Single Diodes Part Context

The FDLL4151 belongs to the Fairchild Semiconductor family of small signal diodes designed for general-purpose use. It is functionally related to other devices in the LL-34 series, such as the FDLL4150, which shares similar surface-mount characteristics. These components are engineered to provide reliable performance in standard electronic circuits where moderate voltage blocking and fast recovery are required.
