The STPS10170CR from STMicroelectronics is a versatile, high-voltage rectifier, specifically designed for power supply and motor drive applications. This diode array offers superior ESD, surge and thermal protection, along with low ON-State losses and excellent reverse leakage performance.

The STPS10170CR is designed for use in applications requiring a broad range of voltage, current and thermal performance. It is an encapsulated, isolated array of six ultra-low-forward voltage silicon Schottky diodes in a four-terminal package. Its goal is to provide a low-profile, high-current and high-voltage diode array that protects against up to 400 Vdc reverse bias.

The STPS10170CR is a perfect fit for applications such as motor drives, power supplies, and power converters. Its superior surge immunity, high current capacity, and low reverse leakage make it an ideal choice for industrial and automotive applications. Its reverse steady state breakdown voltage (BVR) of 400 V allows the diode to be used in high power applications with high voltage swings, reducing the number of components needed for the system or circuit.

The STPS10170CR has a wide operating temperature range from -40 to 150°C. It offers high temperature stability with a thermal resistance of 10°C/W from junction to ambient. These features, along with its high level of insulation, make the STPS10170CR suitable for use in a wide range of environments. This diode array also has low conduction losses due to its low dynamic forward voltage, making it ideal for high efficiency applications.

The working principle of the STPS10170CR is based on the PN junction concept. When the diode is reversed biased, the depletion region created by the hole and electron pairs allows no current to flow through the junction. When forward biased, however, the depletion region shrinks and current is allowed to flow freely through the junction. This in turn allows the circuit to be powered and the motor to be driven.

In summary, the STPS10170CR is an ideal choice for power supply and motor drive applications, thanks to its superior ESD, surge and thermal protection, ultra-low forward voltage, and high reverse voltage capability. This versatile diode array is a cost-effective solution for designers looking for a reliable, power efficient option for their applications.
