HSMP-4810

The HSMP-4810 and HSMP-381X series are specifically designed for low distortion attenuator applications. The HSMP-382X series is optimized for switching applications where ultra-low resistance is required. The HSMP-3880 switching diode is an ultra low distortion device optimized for higher power applications from 50 MHz to 1.5 GHz. The HSMP-389X series is optimized for switching applications where low resistance at low current and low capacitance are required. The HSMP-4810 series are special products featuring ultra low parasitic inductance in the SOT-23 package, specifically designed for use at frequencies which are much higher than the upper limit for conventional SOT-23 PIN diodes. The HSMP-4810 diode is a low distortion attenuating PIN designed for operation to 3 GHz. The HSMP-4820 diode is ideal for limiting and low inductance switching applications up to 1.5 GHz. The HSMP-4890 is optimized for low current switching applications up to 3 GHz.

The HSMP-4810 series of general purpose PIN diodes are designed for two classes of applications. The first is attenuators where current consumption is the most important design consideration. The second application for this series of diodes is in switches where low cost is the driving issue for the designer.

The HSMP-4810 series Total Capacitance (CT) and Total Resistance (RT) are typical specifications. For applications that require guaranteed performance, the general purpose HSMP-383X series is recommended. For low distortion attenuators, the HSMP-380X or -381X series are recommended. For high performance switching applications, the HSMP-389X series is recommended.

A SPICE model is not available for PIN diodes as SPICE does not provide for a key PIN diode characteristic, carrier lifetime.
