BT258X-500R,127 Description

Short technical summary and product information.

The NXP Semiconductors BT258X-500R,127 is a thyristor designed for circuit protection applications. It offers a maximum off-state voltage of 500V and a peak surge current capability of 75A. The continuous load current is rated at 5A.

 

This component is housed in a TO220FP package and utilizes through-hole mounting. Its specifications make it suitable for various power control and switching applications where reliable overvoltage protection is required.

 

As a thyristor, it acts as a bistable semiconductor device with two stable states: a low-conductivity state and a high-conductivity state. It is triggered into the high-conductivity state by a gate pulse and remains conducting until the current drops below a certain level or is interrupted.

 

This part is manufactured by NXP Semiconductors, a well-known provider of semiconductor solutions. The BT258X-500R,127 is identified by manufacturer part number BT258X-500R.127.
