HSMP-389C-TR2G

RF Diode Overview

The HSMP-389C-TR2G is a surface mount RF PIN switch diode from the HSMP-389x series, manufactured by Broadcom Limited. It features a Series configuration housed in an SOT-323 package with a -TR2G tape and reel option containing 10,000 devices. Key electrical specifications include a breakdown voltage (VBR) of 100 V, a maximum series resistance (RS) of 2.5 Ohms at 5 mA forward current, and a total capacitance (CT) of 0.30 pF at 5 V reverse bias. The device operates within a junction temperature range of -65°C to +150°C.

RF Diode Feature Summary

• Optimized for switching applications requiring low resistance at low current and low capacitance.
• Features matched diodes to ensure consistent performance across units.
• Designed for high-frequency operation well beyond conventional PIN diode limits.

RF Diode Applications

• RF switching circuits requiring low parasitic capacitance.
• High-frequency signal routing and attenuation.
• Transmit/Receive switches in communication systems.

RF Diode Procurement Notes

Verify the specific ordering suffix -TR2G corresponds to the required 10,000-unit tape and reel packaging format. Confirm that the SOT-323 package outline matches the target PCB footprint dimensions. Ensure compatibility with lead-free reflow soldering profiles as specified in the assembly guidelines.

RF Diode Selection Notes

Select this component when a Series configuration is required for RF paths. Compare the 0.30 pF capacitance and 2.5 Ohm series resistance against circuit impedance requirements. Verify that the 100 V breakdown voltage exceeds the peak inverse voltage expected in the application environment.

RF Diode Part Context

This part belongs to the HSMP-389x family of surface mount PIN diodes designed for RF switching. The 'C' designation specifically indicates the Series internal connection topology. The TR2G suffix denotes the bulk tape and reel packaging quantity, distinguishing it from other packaging options like -TR1G or bulk variants.

RF Diode Replacement Considerations

Consult the HSMP-389x datasheet for alternative configurations such as HSMP-3890 (Single) or HSMP-389B (Common Cathode). Verify pinout compatibility if substituting with different internal topologies within the same series.
