HBAT-5402-TR1G

RF Diode Overview

The HBAT-5402-TR1G is a high-performance Schottky diode from the HBAT-540x series, designed for transient suppression and circuit protection. It features ultra-low series resistance (2.4 Ω typical) to handle high forward currents without thermal runaway. The device operates with a peak inverse voltage of 30 V and a DC forward current rating of 220 mA in the SOT-23 package. It exhibits low capacitance (3.0 pF typical) and picosecond switching speeds, making it suitable for preserving signal waveshapes in high-speed digital data lines.

RF Diode Feature Summary

• Ultra-low series resistance enables higher current handling capacity while minimizing power dissipation.
• Low junction capacitance minimizes signal degradation and waveshape loss during high-speed switching.
• Picosecond switching response allows rapid reaction to noise spikes with rise times as fast as 1 ns.

RF Diode Applications

• Circuit protection against high current transients on data lines
• Voltage clamping and clipping applications
• High-speed switching circuits requiring waveshape preservation

RF Diode Procurement Notes

Verify component authenticity by checking manufacturer markings and datasheet specifications. Confirm package type and electrical ratings match design requirements before integration. Ensure proper handling procedures are followed to prevent electrostatic discharge damage during assembly and storage.

RF Diode Selection Notes

Select this component when low series resistance is critical for managing high transient currents without excessive voltage drop. Compare thermal resistance characteristics against alternative packages if operating near maximum junction temperature limits. Verify that the 30 V breakdown voltage meets the system's reverse voltage requirements.
