Overview
The CD0.5A40 is a small-signal Schottky rectifier manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AA (MiniMELF) package. It features a single silicon element with a maximum average forward current of 500 mA and a repetitive peak reverse voltage rating of 40 V. The device exhibits a typical forward voltage drop of 650 mV at rated current and maintains a low reverse leakage current of 10 µA. It operates reliably within a junction temperature range from -65 °C to +150 °C and supports a forward surge current of 5 A.
Feature Summary
- Schottky barrier construction provides fast switching characteristics and low forward voltage drop.
- Hermetically sealed glass MELF package ensures reliability in harsh environments.
- Silicon diode technology offers robust performance under high thermal stress conditions.
Applications
- High-frequency rectification in power supply circuits
- Clamping and protection in signal processing paths
- Reverse polarity protection in low-voltage DC systems
Procurement Notes
Verify the specific suffix and manufacturer designation when sourcing, as historical data indicates variations between Microchip Technology and Compensated Devices Inc for similar part numbers. Confirm RoHS compliance status directly with the supplier, as documentation shows mixed records. Ensure the package type matches the required MiniMELF footprint and validate the operating temperature range against system requirements before integration.
Selection Notes
Select this component for designs requiring a compact, hermetically sealed Schottky rectifier with a 40 V blocking capability. The MiniMELF form factor suits space-constrained PCB layouts. Consider the 500 mA continuous current limit and the 150 °C maximum junction temperature when determining thermal management needs. Verify that the 650 mV forward voltage aligns with the efficiency targets of the target circuit application.
Part Context
This device belongs to the Microchip Technology small-signal Schottky rectifier family, utilizing the DO-213AA package standard. It serves as a discrete semiconductor solution for general-purpose rectification tasks where low capacitance and fast recovery are beneficial. The product line includes variants with different voltage ratings, such as 20 V and 30 V options, sharing identical physical and electrical characteristics except for the reverse voltage specification.
Replacement Considerations
Cross-reference with CDLL0.5A40 for equivalent specifications in the same package style. Verify compatibility with 1N6677 series equivalents if hermetic sealing is not strictly required. Ensure substitute parts match the 40 V reverse voltage and 500 mA current ratings to maintain circuit integrity.
