BAT54S-D87Z

Overview

The BAT54S-D87Z is a dual Schottky barrier diode array in a SOT-23 surface-mount package. It features two series-connected elements with a center tap, providing a maximum repetitive reverse voltage of 30 V and an average rectified forward current of 200 mA per diode. The device exhibits a low forward voltage drop, reaching a maximum of 0.8 V at 100 mA, and maintains a reverse leakage current of 2 µA at 25 V. Thermal characteristics include a power dissipation rating of 290 mW and a junction-to-ambient thermal resistance of 430 °C/W.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packing quantities and tape-and-reel specifications. Ensure the component source aligns with ON Semiconductor or authorized Fairchild Semiconductor distribution channels to guarantee authenticity and traceability. Cross-reference datasheet revision numbers to validate electrical parameter consistency.

Selection Notes

Select this component when a compact dual-diode solution with a center tap is required for signal processing or protection. The SOT-23 form factor supports space-constrained designs. Evaluate the 30 V reverse voltage limit and 200 mA current capacity against peak circuit demands. Consider the 5 ns recovery time for high-frequency operation requirements.
