TRACO POWER TDN34821WI Datasheet & Stock

The TDN 3-4821WI from Traco Power is a 3W regulated dual output DC-DC converter housed in an ultra-compact DIP package measuring 9.1mm x 10.2mm x 13.2mm. It features a 4:1 input voltage range from 18V to 75V DC, with fully regulated output voltages of ±5V DC and a maximum output current of ±300mA. The converter provides high efficiency of 80%, with a minimum switching frequency of 100 kHz (pulse frequency modulation). It offers excellent electrical isolation capabilities, including an I/O isolation voltage of 1600V DC for 60 seconds, greater than 1 GΩ I/O isolation resistance, and 50 pF I/O isolation capacitance. The device includes remote ON/OFF control, continuous short circuit protection with automatic recovery, and a built-in EN 55022 Class A filter. It meets safety standards such as EN 61000-4-2 (ESD) with ±8kV air and ±6kV contact discharge. The case is constructed from UL 94V-0 rated non-conducting FR4 with UL 94V-0 silicone potting and tinned copper pins for durability. It operates reliably across a temperature range from -40°C to 70°C without derating, making it suitable for power management and industrial applications.
