HSMP-4820-BLKG

RF Diode Overview

The HSMP-4820-BLKG is a surface mount RF PIN diode from the HSMP-482x series, designed for low inductance switching and power limiting applications up to 1.5 GHz. It features a dual anode configuration housed in an SOT-323 package with FA marking code. Key electrical specifications include a breakdown voltage of 50 V, a maximum series resistance of 0.6 Ω, and a total capacitance of 0.75 pF at 1 MHz. The device operates within a junction temperature range of -65°C to 150°C and supports a peak inverse voltage of 50 V.

RF Diode Feature Summary

• Optimized for ultra-low inductance switching and power limiting applications
• Dual anode configuration suitable for high isolation SPDT switch circuits
• Lead-free construction compliant with RoHS standards

RF Diode Applications

• High isolation single-pole double-throw (SPDT) switches using dual bias
• Power limiting and circuit protection components
• Low inductance switching applications operating up to 1.5 GHz

RF Diode Procurement Notes

Verify the specific ordering suffix BLKG confirms bulk packaging containing 100 pieces per antistatic bag. Ensure the component matches the Avago Technologies or Broadcom Limited manufacturing origin as indicated on the datasheet. Confirm the FA marking code corresponds to the HSMP-4820 part number during incoming inspection.

RF Diode Selection Notes

Select this component when low parasitic inductance is critical for switching speeds up to 1.5 GHz. The dual anode structure allows for flexible circuit topologies requiring common cathode connections. Verify that the 50 V breakdown voltage meets the system's peak reverse voltage requirements.

RF Diode Part Context

This component belongs to the HSMP-382x and HSMP-482x family of surface mount RF PIN diodes manufactured by Broadcom Limited (formerly Avago Technologies). The HSMP-482x series specifically targets applications demanding lower inductance compared to standard PIN diodes, making it suitable for higher frequency microwave operations.

RF Diode Replacement Considerations

The HSMP-3820 serves as a single diode alternative within the same series but lacks the dual anode configuration required for specific bridge or balanced switch topologies used with the HSMP-4820.
