MSS25-143-H27

RF Diode Overview

The MACOM MSS25-143-H27 is a P-type silicon Schottky detector optimized for superior 1/f noise performance. It requires a small forward bias of 5 to 50 µA for microwave detection at power levels below -30 dBm and functions as a zero-bias detector at higher powers. Key electrical specifications include a typical forward voltage of 260 mV (max 300 mV) at 1 mA, junction capacitance of 0.08 pF (max 0.10 pF), and dynamic resistance of 60 Ω (max). The device supports frequencies up to 26 GHz and operates within a temperature range of -65°C to +150°C.
