SBT250-04Y-DL-E

Diodes - Rectifiers - Arrays

The SBT250-04Y-DL-E is an array of discreet rectifiers mainly used in power supply applications. It is essentially a silicon Silicon Bridge Rectifier array consisting of four ultra-fast rectifiers, each rated for peak forward surrents of 4 amperes at a junction temperature of 150C. Its a 4-terminal device with four terminals – two cathode and two anode. The maximum ratings for each terminal are 250V at 2A. The unit has a fast reverse recovery time and offers high surge current capability.

Applications

The SBT250-04Y-DL-E is mainly used for rectification and filtering of power and low-voltage signals. It is ideal for converting AC to DC in applications such as motor drives, power supplies, medical equipment, telecom devices and automotive circuits. It can also be used to rectify and buffer inputs in power distribution systems, lighting systems, and electrical devices.

Working Principle

The SBT250-04Y-DL-E operates on the principle of four ultra-fast rectifiers. The rectifiers provide current flow in only one direction, allowing it to convert AC voltage to DC voltage. When an AC voltage is applied, the rectifiers allow current flow through the diode’s connected cathode and the diode’s connected anode terminal, depending on the direction of that current. As the AC voltage reverses, the diodes switch roles and this process continues as long as an external voltage is applied. The array ensures that the voltage and current remain relatively constant, regardless of external voltage fluctuations.

Conclusion

The SBT250-04Y-DL-E is a four-terminal array of rectifiers which are mainly used for rectification and filtering of power and low-voltage signals. Its fast reverse recovery time and high surge current capability make it suitable for a range of DC conversion applications. It operates on the principle of four ultra-fast rectifiers which allow current flow only in one direction, allowing it to efficiently convert AC voltage to DC voltage.
