The Q36SR12020NRFH is a 240W isolated DC/DC power module in an industry-standard quarter-brick package, designed to convert a wide input voltage from 18V to 75V into a regulated 12V output. It delivers a continuous output current of 20A and achieves a high typical efficiency of 93.0% at 48V input under full load. This model includes an integrated heat spreader for enhanced thermal performance and features negative on/off logic. Key protective features include input undervoltage lockout (UVLO), over-temperature protection (OTP), output over-voltage protection (OVP), and over-current protection (OCP). These characteristics make it suitable for high-reliability applications such as data networking, communications, servers, and optical transport.
