RF Diode Procurement Notes

Verify the ordering suffix TR2G corresponds to the 10,000-unit 13-inch reel quantity specified in the datasheet. Confirm the manufacturer designation, as Broadcom Limited acquired Avago Technologies, which originally produced this component. Ensure the part number matches the specific SOT-23 single configuration rather than the series pair variants.

RF Diode Selection Notes

Select the HBAT-5400-TR2G when low series resistance is critical for high-current transient protection in SOT-23 packages. Compare thermal resistance characteristics against the SOT-323 variant if higher steady-state current handling is required. Utilize the provided SPICE model parameters for accurate simulation of junction temperature and forward voltage behavior under varying load conditions.

RF Diode Part Context

This component belongs to the HBAT-540x family of Schottky clipping and clamping diodes. It shares core electrical characteristics with the HBAT-5402 but differs in packaging and reel quantity. The series is optimized for preserving circuit waveforms while providing robust protection against data line noise spikes in digital and RF environments.

RF Diode Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided datasheet. Designers should evaluate other Schottky diodes with comparable series resistance (approx. 2.4 Ω) and capacitance (approx. 3.0 pF) specifications for functional equivalence.
