SK1535-TP diodes, belonging to Rectifiers - Single, are widely used in telecom, power supply, solar energy, energy storage and other applications for power rectification, voltage and current regulation, etc. They offer excellent capability in current capacity, recovery time and anti-surge ability.

SK1535-TP is a high-speed thyristor recovery diode. It features with a high reverse peak voltage rating of 1535V, and low forward voltage drop of 0.42 V @ 1A. It has not only fast reverse recovery time, but also low power dissipation. The junction temperature can be up to 165 ℃. SK1535-TP also has low forward voltage and low reverse current characteristics.

SK1535-TP is ideal for fast switching applications such as switching power supplies, inverters, converters, isolated DC-DC converters, phase control SCR driving and snubbers. In those applications, it can improve the performance of the devices by reducing the switching losses and handling high frequency pulses.

The working principle of SK1535-TP is based on the P-N junction switching operation. When the power is switched off, the diode enters a reverse breakdown state. During this time, electrons and holes recombine and heat is generated, requiring cooling of the diode. When the reverse voltage is removed, the diode returns to a forward conduction state allowing forward current to flow. During this state, the forward voltage drop of the diode limits the current flow.

In addition to the traditional fixed forward voltage drop, the SK1535-TP is also available with a variable voltage drop that can be adjusted using an external control voltage. This feature allows the power supply or regulating device to control the current flow, thus providing dynamic control over the load current. The control voltage also affects the reverse recovery time.

Overall, SK1535-TP is a highly reliable and efficient diode. It is extremely popular in a wide range of applications. It offers very fast switching times, low forward voltage drop and low junction temperature. Moreover, the variable voltage drop feature makes it extremely versatile, allowing dynamic control over the load current. As a result, SK1535-TP is one of the best choices for high-speed power rectification and voltage/current regulations in a wide range of applications.
