HSMS-286B-BLKG

RF Diode Overview

The HSMS-286B-BLKG is a surface mount microwave Schottky detector diode from the HSMS-286x series, manufactured by Broadcom Limited. It is housed in a miniature SOT-323 (SC-70) package with three leads and operates as a single diode configuration. The device is optimized for RF/ID and RFID applications across frequencies from 915 MHz to 5.8 GHz. Key electrical specifications include a peak inverse voltage of 4.0 V, a typical forward voltage of 250 mV at 1.0 mA, and a junction capacitance of 0.25 pF at 0 V reverse bias and 1 MHz. It exhibits high detection sensitivity, reaching up to 50 mV/µW at 915 MHz, 35 mV/µW at 2.45 GHz, and 25 mV/µW at 5.80 GHz.
