HSMP-481B-BLKG

RF Diode Overview

The HSMP-481B-BLKG is a single silicon PIN diode from Broadcom Limited, housed in an SOT-323 (SC-70) surface-mount package with three leads. It features a minimum breakdown voltage of 100 V and a maximum total capacitance of 0.4 pF at 50 V reverse bias. The device exhibits a maximum series resistance of 3 Ω at 100 mA forward current and a typical total inductance of 1 nH. Operating temperatures range from -65 °C to +150 °C, with a junction temperature limit of 150 °C.

RF Diode Feature Summary

• Optimized for low distortion attenuating applications
• Features ultra-low parasitic inductance for microwave frequency operation
• Available in lead-free tape and reel or bulk packaging options

RF Diode Applications

• Low distortion RF attenuators
• Microwave frequency switching circuits
• Ultra-high frequency to S-band signal processing

RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. Confirm that the BLKG designation corresponds to bulk packaging quantities as specified by the manufacturer. Ensure compatibility with RoHS standards if required by the application environment. Cross-reference the datasheet revision date to confirm parameter validity.

RF Diode Selection Notes

Select this component when ultra-low inductance is critical for high-frequency performance above 500 MHz. The 100 V breakdown rating supports higher power handling compared to lower-voltage variants. Verify that the SOT-323 footprint aligns with the PCB layout constraints and thermal management requirements of the target design.

RF Diode Part Context

This part belongs to the HSMP-481x series of surface mount RF PIN diodes designed specifically for low inductance applications. It shares the same electrical characteristics as the HSMP-481B but differs in packaging configuration. The series is engineered to outperform conventional diodes in microwave frequency ranges.

RF Diode Replacement Considerations

The HSMP-481B serves as the base model for this variant. Other members of the HSMP-481x family share identical electrical specifications but may differ in package type or internal lead configuration.
