• Features a low failure in time (FIT) rate for reliability
• Available in lead-free packaging options

RF Diode Applications

• RF switching circuits requiring ultra-low resistance
• Low distortion attenuating systems
• Power limiting and circuit protection modules

RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type. The BLKG suffix indicates bulk packaging containing 100 pieces per antistatic bag. Confirm availability status as distribution channels may vary. Ensure compliance with RoHS directives if required by the application environment.

RF Diode Selection Notes

Select this component when a Series PIN diode configuration is necessary for high-isolation switching or attenuation. The SOT-23 package suits space-constrained designs. Evaluate the 1.5 Ω series resistance and 0.6 pF capacitance against system impedance requirements. Consider the 50 V breakdown voltage for appropriate reverse bias margins in the target circuit topology.

RF Diode Part Context

This part belongs to the HSMP-382x family of surface mount RF PIN switch and limiter diodes manufactured by Broadcom Limited. The series includes single, dual, common anode, and common cathode variants. The HSMP-3822 specifically denotes the Series configuration within this lineup, distinct from the single-diode HSMP-3820 or the common cathode HSMP-3824.

RF Diode Replacement Considerations

Direct substitutes within the same series include HSMP-3820 (Single), HSMP-3823 (Common Anode), and HSMP-3824 (Common Cathode). Cross-series alternatives like the HSMP-482x offer lower inductance but differ in package and electrical characteristics. Verify pinout compatibility and electrical parameters before substitution.
