HSMP-389L-BLKG

RF Diode Overview

The HSMP-389L-BLKG is a surface mount RF PIN switch diode from Broadcom Limited, housed in an SOT-363 package with three leads. It features an unconnected trio configuration designed for switching applications requiring low resistance at low current and low capacitance. The device has a peak inverse voltage of 100 V, a maximum series resistance of 2.5 Ω at 5 mA forward current, and a total capacitance of 0.3 pF at 5 V reverse bias. Operating temperatures range from -65 °C to +150 °C, with a junction temperature limit of 150 °C.

RF Diode Feature Summary

• Optimized for switching applications where low resistance at low current and low capacitance are required
• Features ultra-low parasitic inductance suitable for frequencies much higher than the upper limit for conventional PIN diodes
• Includes matched diodes for consistent performance across multiple units

RF Diode Applications

• SP3T Switch configurations
• Dual Voltage High Isolation Switches
• Positive Voltage High Isolation Switches

RF Diode Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix BLKG indicates bulk packaging containing 100 pieces per antistatic bag. Ensure compliance with RoHS directives and lead-free assembly requirements during procurement planning.

RF Diode Selection Notes

Select this component when designing circuits that require an unconnected trio configuration within a compact SOT-363 footprint. Consider the 100 V breakdown voltage and 0.3 pF capacitance specifications for high-frequency signal routing. Evaluate thermal resistance parameters if operating near the maximum junction temperature limits.

RF Diode Part Context

This part belongs to the HSMP-389x series of surface mount RF PIN switch diodes. The series includes various configurations such as single, series, common anode, common cathode, and dual switch modes. The HSMP-389L specifically provides an unconnected trio setup, offering flexibility for complex switching topologies while maintaining low parasitic effects.

RF Diode Replacement Considerations

Direct substitutes include other parts from the HSMP-389x series with matching configurations, such as HSMP-3890 (Single) or HSMP-389B (Single). For unconnected trio needs, verify pinout compatibility and electrical parameters against similar offerings from the same manufacturer family.
