TheS85VR is a product from Diodes Incorporated, categorized as Single Rectifiers. It is a two-terminal device specifically designed for power protection applications. It is ideal for use in a wide range of high performance, DC-DC, and AC-DC power supplies, as well as motor and power converters. This device is also present in other applications, such as hot-swapping, over-current protection, pulse rectification, and high speed switching.

The S85VR provides a tight tolerance solution to ensure it meets the most demanding applications. It features a high voltage rating of 200V, low current of 0.3A, forward voltage drop of 1.2V typical, and reverse leakage current of 100uA @ 25°C. Additionally, the device is rated for high-temperature operation from -55°C to 115°C and is a hermetically sealed device for maximum reliability and long life.

The S85VR is an ultra-fast free-wheeling, low voltage power protection diode that functions as a single direction protection element. Its primary function is to protect a circuit from reverse voltage transients. It prevents power supply components from being damaged by current overloads caused by short circuits, over voltage, or similar faults. During normal operation, the S85VR has a small leakage current, but then automatically looks into valuable protection mode when the voltage exceeds its breakdown voltage. When the reverse voltage exceeds the breakdown voltage, the S85VR begins to conduct current, drawing current away from the sensitive load. This means that the S85VR provides a wealth of protection against any type of voltage overshoot, making it indispensable for high-end power supply designs.

The S85VR’s simple working principle makes it an ideal choice for a wide array of power protection applications. Its easy to Integrate into existing designs and provides unrivaled protection against voltage transients. In power electronics applications, for example, the S85VR can be used to protect the power converter from damage due to short circuit, over voltage, or over temperature events. The device can also be used in motor DC drives to monitor their output voltage from potential dangerous over-voltage events. Likewise, the S85VR can be used to protect AC-DC power supplies from potential overvoltage conditions, as well as to protect Switch-Mode Power Supplies (SMPS) from over-voltage or over-temperature conditions.

In short, the S85VR is a powerful and practical device for any number of power protection applications. With a high voltage rating of 200V, low current of 0.3A, forward voltage drop of 1.2V typical, and reverse leakage current of 100uA @ 25°C, it is the ideal solution for any design requiring power protection. In addition, its hermetically sealed construction and wide operating temperature range make it a long-lasting and reliable protection device in any power supply design.
