HSMP-3864-BLKG

RF Diode Overview

The HSMP-3864-BLKG is a general-purpose silicon PIN diode from the HSMP-386x series, manufactured by Broadcom Limited. It features a common cathode configuration housed in an SOT-23 surface-mount package. The device is rated for a peak inverse voltage of 50 V and supports a forward current of 1 A under pulse conditions. Key electrical specifications include a typical total capacitance of 0.20 pF at 1 MHz and a reverse recovery time of 80 ns. The component operates within a temperature range of -65°C to +150°C.

RF Diode Feature Summary

• Designed for low distortion switching applications requiring minimal capacitance.
• Optimized for attenuator circuits where low current consumption is critical.
• Utilizes matched diodes to ensure consistent performance across configurations.

RF Diode Applications

• Single-Pole Double-Throw (SPDT) RF switches
• High isolation SPST switches
• Low power RF attenuators

RF Diode Procurement Notes

Verify the specific ordering suffix to confirm packaging format, as options include bulk or tape and reel configurations. Confirm RoHS compliance status through official documentation prior to integration. Ensure the design accounts for the lead-free reflow profile requirements specified in the assembly guidelines to maintain device integrity during manufacturing.

RF Diode Selection Notes

Select this component when board space is limited due to its compact SOT-23 footprint. Choose the common cathode variant if the circuit design requires shared cathode connections for multiple diode arrangements. Verify that the system's minimum operating frequency exceeds ten times the cutoff frequency determined by the carrier lifetime to prevent nonlinear reactance.

RF Diode Part Context

This part belongs to the HSMP-386x family of surface mount PIN diodes. The series offers various internal configurations, including single, series, common anode, and common cathode setups, all sharing similar electrical characteristics. The BLKG suffix specifically denotes the bulk packaging option containing 100 pieces per antistatic bag.

RF Diode Replacement Considerations

The HSMP-386F-BLKG serves as a direct functional substitute, offering identical electrical parameters but utilizing a Common Cathode configuration within an SOT-323-3 package instead of SOT-23. Designers must verify pinout compatibility and thermal resistance differences between the SOT-23 and SOT-323 packages before substitution.
