HSMS-286L-BLKG

RF Diode Overview

The HSMS-286L-BLKG is a surface mount microwave Schottky detector diode from the HSMS-286x family, manufactured by Broadcom Limited. It features an unconnected trio configuration within a miniature SOT-323 package. The device is optimized for operation between 915 MHz and 5.8 GHz, supporting applications such as RF/ID tags, large signal detection, modulation, and voltage doubling. Key electrical specifications include a typical forward voltage of 250 mV at 1.0 mA and a maximum capacitance of 0.25 pF at 0 V reverse bias and 1 MHz. Absolute maximum ratings specify a peak inverse voltage of 4.0 V and an operating temperature range from -65°C to +150°C.
