HSMP-386F-BLKG

RF Diode Overview

The HSMP-386F-BLKG is a silicon PIN diode from the Broadcom HSMP-386x series, housed in an SOT-323 surface-mount package. It features a common cathode configuration with four leads. Key electrical specifications include a peak inverse voltage of 50 V and a total capacitance of 0.2 pF at 1 MHz under 50 V reverse bias. The typical series resistance is 1.5 Ω at 10 mA forward current, while the total resistance is 22 Ω at 1 mA. The device supports a maximum forward current of 1 A (1 µs pulse) and operates within a temperature range of -65°C to +150°C.

RF Diode Feature Summary

RF Diode Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for Product Change Notices (PCN) regarding manufacturing updates. Ensure storage conditions adhere to specified limits to prevent degradation prior to assembly.

RF Diode Selection Notes

Select this component when a common cathode PIN diode with minimal parasitic capacitance is required for RF signal routing. The SOT-323 package suits space-constrained designs. Verify that the 50 V breakdown voltage meets the circuit's peak inverse voltage requirements and that the thermal resistance accommodates the expected power dissipation.

RF Diode Part Context

This part belongs to the HSMP-386x general-purpose PIN diode family. Variants within the series differ by internal configuration, such as single, series pair, or common anode arrangements. The HSMP-386F specifically provides the common cathode topology, distinguishing it from other members like the HSMP-386B (Single) or HSMP-386E (Common Anode).

RF Diode Replacement Considerations

Direct substitutes within the same series include HSMP-3864-BLKG (SOT-23-3 package) and HSMP-3860-BLKG (SOT-23 package), provided the pinout and package footprint differences are addressed in the PCB layout.
