The STPS30170CFP rectifier diode array offers several features, such as:

• Low forward voltage drop.

• High-speed switching, with a maximum on-state resistance of 0.75 ohm.

• Low power consumption with low power dissipation.

• Short-circuit protection.

• High thermal efficiency with a maximum junction temperature of 175 ˚C.

• Surge and temperature cycling capabilities.

Working Principle

The working principle of the STPS30170CFP rectifier diode array is based on the forward current-voltage characteristics, which are determined by the junction temperature and input voltage of the diode, along with the values of the current-limiting resistor. When an alternating current (AC) voltage is applied to the diode array, the diode’s internal junction temperature rises slowly and the output voltage increases proportionally. When the peak (or maximum) value of the input voltage exceeds the diode’s breakdown voltage, the current flows through the diode and its junction temperature increases, and at the same time the voltage across the diode decreases, leading to a soft start of the rectifier diode array.

When the voltage decreases and becomes less than the breakdown voltage of the diode, the current flow stops, and the diode’s junction temperature returns to its original state. This continues in a cyclical fashion with the current alternating on and off for each cycle of the applied voltage. The speed of switching is determined by the size of the current-limiting resistor, as well as by the characteristics of the diode itself.
