HSMP-386B-BLKG

RF Diode Overview

The HSMP-386B-BLKG is a general-purpose silicon PIN diode from the HSMP-386x series, manufactured by Broadcom Limited. It features a single diode configuration housed in an SOT-323 (SC-70) surface-mount package. The device has a breakdown voltage of 50 V and a typical total capacitance of 0.20 pF at 1 MHz with 50 V reverse bias. Its typical series resistance is 3.0 Ω at 10 mA forward current and 1.5 Ω at 100 mA. The component supports a maximum forward current of 1 A under pulse conditions and operates within a junction temperature range up to 150°C.

RF Diode Feature Summary

• Designed for low distortion switching applications requiring minimal capacitance.
• Optimized for low current attenuating functions to reduce power consumption.
• Utilizes matched diodes within the series for consistent performance characteristics.
• Offers enhanced thermal conductivity to support higher power dissipation capabilities.

RF Diode Applications

• Low distortion RF switching circuits
• Low current attenuator designs

RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The -BLKG suffix indicates bulk packaging containing 100 pieces per antistatic bag. Confirm that the SOT-323 package variant matches the design requirements. Ensure compliance with lead-free assembly standards as specified in the datasheet.

RF Diode Selection Notes

Select this component when low capacitance is critical for switch isolation or when low forward current is preferred for attenuator efficiency. Compare the 0.20 pF capacitance and 50 V breakdown voltage against circuit requirements. Consider the SOT-323 footprint constraints and thermal resistance specifications for the application environment.

RF Diode Part Context

This part belongs to the HSMP-386x family of surface mount PIN diodes produced by Broadcom Limited. The series includes various configurations such as single, series, common anode, and common cathode arrangements. The HSMP-386B specifically denotes the single diode version within this lineup, distinct from paired or multi-diode variants like the HSMP-386C or HSMP-386F.

RF Diode Replacement Considerations

Direct substitutes within the same series include HSMP-3860, HSMP-386C, HSMP-386E, and HSMP-386F, which share similar electrical characteristics but differ in internal configuration. Verify pinout compatibility and package dimensions before substitution.
