SIOV-B25K420 Description

Short technical summary and product information.

The Siemens SIOV-B25K420 is a metal oxide varistor (MOV) designed for robust protection against voltage transients. It is housed in a plastic case with screw terminals for easy mounting.

 

Key electrical characteristics include a maximum operating AC voltage of 505V RMS and a maximum operating DC voltage of 100,000V. This varistor can handle a maximum surge current of 2000A (8/20 µs) and has a maximum energy absorption capacity of 2.0 Joules (2 ms). The nominal varistor voltage is 620V at 1 mA, with a tolerance of -10%. The maximum clamping voltage is 1000V.

 

This component is suitable for through-hole mounting and features screw-type terminations, making it suitable for applications requiring high surge current handling and reliable overvoltage protection. The typical capacitance is 100nF.

 

Environmental compliance includes RoHS3 compliance, MSL 1, and REACH unaffected status, though these are currently unverified.
