The ERD110RFZ is a digital input transistor with an assembled lead-free package that is manufactured by Excel Cell Electronic (ECE). The package is designed to be used as an input stage for digital circuits. It has a maximum voltage rating of 5V, a collector current rating of 10mA and an operational temperature range of -55°C to +150°C. The ECE ERD110RFZ is a three-terminal ultra-micro type device commonly used in logic level translation, level matching and BJT logic families such as TTL and CMOS.
