RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging quantity and container type. The TR1G suffix indicates a 7-inch reel containing 3000 units. Ensure compliance with RoHS standards and lead-free requirements as specified in the datasheet before procurement.

RF Diode Selection Notes

Select this component when system design demands a miniature SOD-523 form factor combined with high isolation characteristics. The 100 V breakdown voltage supports moderate reverse bias applications, while the 200 ns carrier lifetime suits high-speed switching frequencies above the cutoff threshold.

RF Diode FAQ

Is a SPICE model available for the HSMP-389Y?

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

What is the typical carrier lifetime of the HSMP-389Y?

The typical carrier lifetime is 200 ns, measured under conditions of 10 mA forward current and 6 mA reverse current.

How does the RF resistance vary with forward current?

The RF resistance decreases as the forward bias current increases, dropping significantly from approximately 3.8 Ω at 1 mA to lower values at higher currents like 10 mA.
