HBAT-540C-TR2G

RF Diode Overview

The HBAT-540C-TR2G is a high-performance Schottky diode from the HBAT-540x series, designed for transient suppression and circuit protection. It features a series configuration of two matched diodes in an SOT-323 (SC-70 3-lead) package. Key electrical specifications include a typical forward voltage of 800 mV at 100 mA, a breakdown voltage of 30 V, and a total capacitance of 3.0 pF. The device exhibits low series resistance of 2.4 Ω and a carrier lifetime under 100 ps. Absolute maximum ratings specify a DC forward current of 430 mA, peak surge current of 1.0 A, and total power dissipation of 825 mW. The junction temperature range extends up to 150°C.

RF Diode Feature Summary

• Ultra-low series resistance enables higher current handling capacity for protecting sensitive circuits against high current transients.
• Picosecond switching response allows the device to react to noise spikes with rise times as fast as 1 ns.
• Low capacitance minimizes waveshape loss and prevents signal degradation in high-speed applications.
• Integrated series pair provides closely matched characteristics without additional testing or binning expenses.

RF Diode Applications

• RF and computer designs requiring circuit protection
• High-speed switching applications
• Voltage clamping and clipping/clamping circuits

RF Diode Procurement Notes

Verify the ordering suffix TR2G corresponds to the 10,000-unit quantity on a 13-inch reel as specified in the official datasheet. Confirm that the component is lead-free if RoHS compliance is required for the specific manufacturing batch. Ensure the supplier documentation matches the Avago Technologies part identification to avoid counterfeit components.

RF Diode Selection Notes

Select the HBAT-540C variant over the HBAT-540B due to its copper leadframe, which offers significantly lower thermal resistance (110°C/W vs 460°C/W). This thermal advantage allows the SOT-323 package to safely handle nearly twice the steady-state current compared to the SOT-23 package. Consider the 2.4 Ω series resistance when designing for high-current transient suppression scenarios.

RF Diode Part Context

This component belongs to the HBAT-540x family of high-performance Schottky diodes manufactured by Broadcom Limited (formerly Avago Technologies). The series is specifically engineered for transient suppression where low series resistance and fast switching are critical. The HBAT-540C utilizes the SOT-323 package to maximize current handling capabilities through improved thermal management compared to smaller packages.
