The VS-T85HFL80S05 is a rectifier diode from Vishay Semicondutors and is part of their ultra-fast such series of products. It is composed of the material Silicon (Si) and generally used for fast switching applications.The device is housed in the ultra-fast, SMD case for efficient thermal management and measures 5.1x4.4 mm. Its maximum rated current is 85A, its peak repetitive peak reverse voltage is 800V, and its maximum non-repetitive surge peak reverse voltage is 1500V. This diode can handle average forward current of 75A and has an average forward current of 35A. The diode has a low reverse current of 10uV at 100V operating temperature.The VS-T85HFL80S05 main application field is the switching mode power supplies (SMPS) and switch mode rectifiers (SMR). It also has applications in the fields of UPS, server power and solar applications. Furthermore, it can be used as a freewheeling diode in high- frequency circuits and as a clamping diode in fast switching low voltage circuits.The working principle behind the device is fairly simple. When forward biased, the device acts as a “switch” allowing an electrical current to flow in one direction. When a voltage is applied to the diode, the diode begins to conduct and there is a low voltage drop across the diode. When the voltage is reversed, the diode will block the flow of current, effectively acting as an insulator.The VS-T85HFL80S05 device displays excellent reverse recovery characteristics and is designed for low power losses and high speed switching. It also comes with a wide operating temperature range so it can be used effectively in a variety of medium to large sized applications.The device has maximum thermal resistance of 1.6K/W, ensuring efficient and fast thermal management. The VS-T85HFL80S05 combines low reverse recovery times (500ns max) with low junction capacitance making it a good choice for designs running at high frequencies.The device also features a fast switching and low forward voltage drop. It has a low on-state resistance and can handle high-temperature operating environments, allowing flexibility in power management design scenarios.The device also comes with a maximum junction temperature of 175°C and is rated up to 1.2KV/sec surge current and 125 Celsius operating temperature.In conclusion, the VS-T85HFL80S05 is a rectifier diode from Vishay Semiconductors, composed of the material Silicon (Si). It is widely used in fast switching applications such as SMPS, switch mode rectifiers, UPS, server power and solar applications. It features excellent reverse recovery characteristics, fast switching and low on-state resistance, making it a good choice for medium to large sized applications.
