BAT54C_D87Z

Overview

The BAT54C_D87Z is a dual Schottky barrier diode array manufactured by onsemi, formerly Fairchild Semiconductor. It features a common cathode configuration within a compact SOT-23 surface-mount package. The device supports a maximum repetitive reverse voltage of 30 V and an average forward current of 200 mA per diode. Key electrical characteristics include a forward voltage of 0.8 V at 100 mA and a low reverse leakage current of 2 µA at 25 V. The component operates reliably across a temperature range from -55 °C to +150 °C junction temperature.

Feature Summary

• Dual Schottky barrier diodes integrated in a single common cathode arrangement for space-efficient circuit design.
• Ultra-fast switching performance with negligible reverse recovery time suitable for high-frequency applications.
• Low forward voltage drop minimizes conduction losses and power dissipation during operation.
• Robust transient protection capabilities provided by PN junction guard ring technology.

Applications

• DC-DC converter output rectification
• RF mixing and detection circuits
• Logic level shifting and clamping

Procurement Notes

Verify the manufacturer origin carefully, as this part was originally produced by Fairchild Semiconductor before its acquisition by onsemi. Ensure the ordering suffix matches the specific packaging requirement, such as cut tape or reel configurations. Confirm RoHS compliance status through the official datasheet documentation provided by the current manufacturer. Cross-reference the part number with updated system requirements if integrating into new designs.

Selection Notes

Select this component when a low-voltage, high-speed switching solution is required in a minimal footprint. The common cathode configuration simplifies biasing compared to separate discrete diodes. Consider the 30 V reverse voltage rating to ensure adequate margin against peak inverse voltages in the target application. Evaluate thermal management needs based on the 200 mA continuous current limit and the small SOT-23 package size.

Part Context

This device belongs to the widely used BAT54 series of Schottky diodes, known for their versatility in signal processing and power management roles. The 'D87Z' suffix typically denotes specific packaging and handling attributes defined by the manufacturer. As part of the onsemi portfolio following corporate integration, it retains the established electrical specifications and mechanical dimensions of the original Fairchild product line.

Replacement Considerations

Direct functional equivalents include the BAT54C without suffix variations or other manufacturers' BAT54C variants. Verify pinout compatibility and electrical parameter tolerances before substitution. Generic replacements must maintain the common cathode configuration and similar forward voltage characteristics to ensure circuit performance integrity.
