FYV0203DSMTF

Diode Arrays Overview

The onsemi FYV0203DSMTF is a Schottky barrier diode housed in an SOT-23 surface-mount package. It features a maximum repetitive reverse voltage of 30 V and an average rectified forward current rating of 0.2 A. The device supports a non-repetitive peak surge current of 0.6 A with a pulse width of 1.0 s. Electrical characteristics include a typical forward voltage drop ranging from 210 mV to 600 mV depending on the forward current, and a total capacitance of 10 pF at 1 V reverse bias. The component operates within a junction temperature range up to 150 °C.

Diode Arrays Feature Summary

• Utilizes Schottky barrier technology for low forward voltage drop and negligible reverse recovery time
• Designed for high-speed switching applications due to minimal charge storage effects
• Constructed in a compact SOT-23 surface-mount package suitable for space-constrained designs

Diode Arrays Applications

• High-frequency rectification in power supply circuits
• Reverse polarity protection in electronic systems
• Clamping and demodulation in RF signal processing

Diode Arrays Procurement Notes

Verify the specific suffix 'SMTF' against official manufacturer documentation to confirm tape-and-reel packaging specifications and moisture sensitivity level. Ensure the sourcing channel provides traceability to Fairchild Semiconductor or authorized onsemi distributors. Confirm RoHS compliance status and check for any lifecycle notices regarding obsolescence before finalizing procurement plans.

Diode Arrays Selection Notes

Select this component when a low-capacitance Schottky diode is required for 30 V reverse voltage applications. The SOT-23 package is appropriate for automated surface-mount assembly processes. Evaluate thermal resistance requirements based on ambient conditions, as the junction-to-ambient thermal resistance is specified at 430 °C/W without additional heatsinking.

Diode Arrays Part Context

This component belongs to the FYV0203 series of small-signal Schottky diodes originally developed by Fairchild Semiconductor. The series includes variants such as FYV0203S, DN, DP, and DS, which differ primarily in pinout configurations and internal connection diagrams while maintaining identical electrical ratings. The product line is designed for general-purpose switching and rectification tasks.

Diode Arrays Replacement Considerations

Direct replacements must match the 30 V reverse voltage, 0.2 A forward current, and SOT-23 package constraints. Verify that alternative Schottky diodes offer comparable forward voltage drops and reverse leakage currents to ensure circuit performance parity.
