STF20120CR

Diodes - Rectifiers - Arrays

STF20120CR is a diode array with a rectifying function, designed to support high-speed switching and power applications. The diode array consists of two chips packaged together in a single unit, as illustrated in the diagram below. Both chips are connected together in an isomorph 1 circuit, providing space and cost savings compared to two separate rectifiers with an external connection.

Application Field

If you’re looking for a diode array for switching and power applications, the STF20120CR is a great choice. It can be used in several applications, including:

• DC-DC and AC-DC voltage regulation
• Switching power supplies
• Detectors for automotive ECUs
• Smartphone charger circuits
• LED lighting control

Working Principle

As a rectifier, the STF20120CR is dependent on the standard rectifying principles, which are:

• When forward biased (by a positive voltage applied to the anode and a negative voltage applied to the cathode), both diodes will conduct, allowing current to flow in one direction.
• When reverse biased (by a negative voltage applied to the anode and a positive voltage applied to the cathode), both diodes will be reverse biased and non-conductive.

The STF20120CR also uses a bipolar voltage structure, which helps reduce the junction capacitance and allows for fast reverse recovery. This helps reduces losses caused by reverse recovery, even for high frequency switching power supplies.

Conclusion

In conclusion, the STF20120CR is a great choice for switching and power applications, due to its isomorph 1 circuit, low junction capacitance and fast reverse recovery. It provides a cost-effective solution compared to two separate rectifiers with an external connection, and is suitable for a wide range of applications.
