RF Diode FAQ

What is the carrier lifetime for the HSMP-386x series?

The typical carrier lifetime for the HSMP-386x series is 500 ns under test conditions of IF = 50 mA.

Is a SPICE model available for this PIN diode?

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

What is the recommended peak reflow temperature for assembly?

The recommended peak temperature during lead-free reflow assembly is 260°C +0/-5°C, conforming to IPC/JEDEC J-STD-020C standards.
