RF Diode Procurement Notes

Verify the specific ordering suffix to confirm packaging format. The -TR1G suffix indicates tape and reel packaging containing 3000 devices per 7-inch reel. Confirm compliance with lead-free assembly requirements and ensure the component matches the required SOT-23 footprint dimensions for automated placement.

RF Diode Selection Notes

Select this component when a single diode configuration is required for RF switching. Ensure the design accommodates the 50 V breakdown voltage and 0.6 Ω series resistance limits. Verify that the SOT-23 package dimensions align with the PCB layout constraints and thermal management requirements for the intended application environment.

RF Diode Part Context

This part belongs to the HSMP-382x series of surface mount RF PIN switch and limiter diodes. The series includes various configurations such as series, common anode, and common cathode arrangements within the same SOT-23 and SOT-323 package families. These diodes are silicon-based components optimized for high-frequency performance.

RF Diode Replacement Considerations

Check datasheets for other HSMP-382x variants like HSMP-3822 or HSMP-3823 if different internal configurations are needed. Verify pinout compatibility and electrical parameters against the HSMP-482x series for low inductance applications.

RF Diode FAQ

Is a SPICE model available for the HSMP-3820?

No, a SPICE model is not available because standard SPICE simulations do not account for carrier lifetime, which is a key characteristic of PIN diodes.

What is the recommended maximum soldering temperature?

The maximum soldering temperature is 260°C for 5 seconds, consistent with lead-free reflow profiles.

How does the HSMP-3820 differ from the HSMP-4820?

The HSMP-3820 is a single diode optimized for general switching, while the HSMP-4820 is a dual anode configuration designed for limiting and low inductance switching applications up to 1.5 GHz.
