It is rated to withstand up to 100V in both reverse and forward bias, making it an ideal choice for applications requiring higher voltage capability. Its reverse current leakage is typically low, at 2µA at 25°C.

In terms of its operating temperature range, the STTH1003SBY-TR can withstand temperatures up to 125°C which makes it suitable for use in a wide range of industrial and automotive applications. The device has a low dynamic impedance and can therefore operate reliably and efficiently over a wide range of operating frequencies.

Working Principle

The STTH1003SBY-TR is a rectifier diode which operates by allowing a one-way flow of current. It acts as a passive electronic component which converts alternating current (AC) to direct current (DC). The device works by allowing current to flow in one direction but blocking the flow in the opposite direction, making it suited for use in AC to DC conversion.

When the anode of the STTH1003SBY-TR is positive compared to its cathode, the diode will be forward biased and the current will flow through it. On the other hand, when the cathode is positive compared to the anode, the diode will become reverse biased and the current will not flow through it. This behavior makes the device act as a one-way switch, allowing current to flow in one direction, while preventing it from flowing in the other.

The STTH1003SBY-TR has a low forward voltage drop which makes it well suited for high-efficiency applications. It can also reach high temperature ratings and withstand high peak forward and reverse currents.

Applications

The STTH1003SBY-TR rectifier diode is suitable for a wide range of applications such as motor control, AC/DC power converters, power switching, and lighting control.
