RF Diode FAQ

What is the carrier lifetime for the HSMP-3822?

The datasheet specifies a typical carrier lifetime of 70 ns at a forward current of 10 mA.

Is a SPICE model available for this diode?

No, a SPICE model is not available because standard SPICE simulation does not account for the key PIN diode characteristic of carrier lifetime.

What is the recommended peak soldering temperature?

The maximum soldering temperature should not exceed 260°C for 5 seconds, following the lead-free reflow profile recommendations.
