BAT54JFILM

Single Diodes Overview

The BAT54JFILM is a single Schottky barrier diode manufactured by STMicroelectronics, housed in an SOD-323 surface-mount package. It features a maximum repetitive reverse voltage of 40 V and an average forward rectified current of 300 mA. The device exhibits a typical forward voltage drop of 900 mV at 100 mA and a low reverse leakage current of 1 µA. Designed for high-speed switching applications, it offers a fast recovery time of 5 ns and supports a non-repetitive peak forward surge current of 1 A. The component operates within a junction temperature range of -40 °C to +150 °C.

Single Diodes Feature Summary

• Utilizes Schottky barrier technology to achieve extremely fast switching speeds with negligible reverse recovery time.
• Provides low conduction losses due to reduced forward voltage characteristics compared to standard silicon diodes.
• Constructed using silicon material for reliable performance across a wide operating temperature range.

Single Diodes Applications

• High-frequency signal detection and mixing circuits
• Clamping and protection of sensitive input/output lines
• Power supply rectification in low-voltage DC-DC converters

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required packaging formats such as cut tape or reel configurations. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary based on production cycles and regional stock levels.

Single Diodes Selection Notes

Select this component when a single-diode configuration is required rather than dual-anode common-cathode arrangements found in other BAT54 variants. Ensure the circuit design accommodates the 40 V reverse voltage limit and 300 mA continuous current rating. Verify that the SOD-323 footprint aligns with the PCB layout constraints and thermal management requirements.

Single Diodes Part Context

This part belongs to the BAT54 series of general-purpose signal Schottky diodes from STMicroelectronics. The series includes various configurations such as dual and triple diodes in packages like SOT-23 and SOT-323. The BAT54JFILM specifically denotes the single-diode version in the compact SOD-323 package, distinguishing it from multi-diode alternatives within the same product family.

Single Diodes Replacement Considerations

Direct substitutes include other single Schottky diodes in SOD-323 packages with comparable 40 V and 300 mA ratings, such as those from ON Semiconductor or Nexperia. Verify pinout compatibility and electrical parameters before substitution.
