The DBT70505U is a normally closed, high-voltage reed relay from the DB(UL) series, designed for applications requiring high reliability and significant voltage isolation. It is constructed with tungsten contacts, enabling it to switch voltages up to 3500V and handle a maximum switching power of 50W. This PCB-mounted relay operates on a 5Vdc coil with a nominal resistance of 38Ω and provides 5kV of isolation across its contacts. Its robust specifications make it suitable for use in demanding equipment such as cardiac defibrillators, high-voltage test equipment, and power supplies.
