The SRT12HA1G is a Rectifier diode designed for use in consumer, automotive and industrial level applications. It is suitable for use in buck converters, resonant converters and in PV cell applications. The SRT12HA1G is a fast switching, very low forward voltage drop Schottky barrier diode. It provides a low capacitance, low forward voltage drop solution for power management applications.

The SRT12HA1G has a rated forward current of 12 A, a forward voltage of 50 V, a maximum reverse voltage of 300 V and a reverse current leakage of 1 µA at 25 °C. It has a junction capacitance of 0.45 pF, reverse recovery time of 30 ns and surge rating of 100 ms. It is rated for operation up to 90 °C, and has a maximum power dissipation of 400 mW.

The SRT12HA1G is designed for use in buck converters, which are used to step down an AC voltage from an input voltage to a lower output voltage. The diode conducts current when the switch is on, allowing the current to flow from the input to the output. When the switch is off, the diode blocks current flow and the output voltage rises to the same level as the input voltage. The diode provides a very low forward voltage drop, which helps reduce power losses while also providing a fast recovery time.

The SRT12HA1G is also suitable for use in resonant converters. These converters switch between inductive and capacitive operation to regulate between a higher and a lower output voltage. The diode provides an alternative path for the current when the inductor is discharging, which helps the output voltage to remain within a desired range. The fast switching of the diode helps to reduce losses and increases efficiency.

The SRT12HA1G is also suitable for use in photovoltaic (PV) cell applications. In these applications, the diode is used to prevent the current from flowing back from the PV cell array to the battery or power source in the event of a short circuit. The low forward voltage drop and fast switching of the diode helps to reduce the power losses associated with the short circuit.

In summary, the SRT12HA1G is a very low forward voltage drop single Schottky barrier diode suitable for a wide range of applications. It is designed for fast switching and suitable for use in buck converters, resonant converters and PV cell applications. With its low capacitance, low forward voltage drop and fast recovery time, the SRT12HA1G is an ideal choice for power management applications.
