DB3S315E0L Discrete Semiconductor Products

Introduction

DB3S315E0L is a Rectifiers Array manufactured by Diodes Incorporated. It is most suitable for use in applications requiring high current rectification. The device features high efficiency, low separate forward voltage, fast reverse recovery time and a thermally enhanced package.

Application Field

DB3S315E0L is a high current rectifier typically used in AC to DC power supplies, DC motor controls and metering applications such as AC line voltage, resistive load and current controlled loads. It is also suitable for use in automotive power supplies, AC line rectification, and secondary rectification in IGBT/MOSFET converters to secure a low switching gate voltage.

Working Principle

The DB3S315E0L functions as an isolated diode array. It contains three isolated diode, each comprising of a pair of anode and cathode terminals. These isolated diodes are configured in a forward conducting mode, allowing current to flow through each of the three diodes when a particular forward voltage is applied across the device terminals.

In normal operation, the device conducts during the forward half cycle of the input signal and blocks the reverse half cycle. During the blocked half cycle, current reverse bias is applied on the diodes, which results in a reliable rectification from AC to DC. The efficiency of the device is mainly depended on the peak current rating and the forward voltage.

The DB3S315E0L is thermally enhanced package comprised of Multiple Source Terminals (MST), Cathode Connection – Common (CC), and Anode Connection – Common (AC) for easy mounting and heat dissipation. This device usually contains three phase current input, which makes it suitable for 3-phase AC to DC rectification and integrated AC motor control.

Conclusion

In conclusion, the DB3S315E0L is a rectifier array manufactured by Diodes Incorporated. It can be used in various applications that require high current rectification such as AC to DC power supplies, DC motor controls, metering applications and more. Its working principle is based on the principle of an isolated diode array, allowing current to flow through the diodes when a particular forward voltage is applied across the device terminals resulting in dependable rectification.
