V10150SHM3/4W

V10150SHM3/4W diodes are part of the single rectifier diode family, which is used to convert alternating current (AC) to direct current (DC). The single rectifier is composed of two semiconductor layers that share two terminals, the anode and cathode. When a positive voltage is applied to the anode and a negative voltage to the cathode, a signal current passes through the device, allowing the AC voltage to become DC without additional components.

The V10150SHM3/4W is specifically designed for use in high voltage and high power applications. It has a reverse voltage rating of 150V and a forward current rating of 150 mA. It can handle high-power loads, up to 10 W and is available in a miniature package, making it ideal for use in space-constrained applications. This device also exhibits a low reverse current leakage, making it suitable for use in high voltage applications, such as AC-to-DC converters and switch-mode power supplies.

The working principle of the V10150SHM3/4W is based on the impact ionization process. When an external voltage is applied to the device, a small leakage current starts to flow. This current is composed of a few electrons that are injected in the depletion layer, resulting in an impact ionization event. This event generates a new avalanche current that flows in the depletion layer. This process continues until the junction voltage is reached, at which point the circuit is saturated and the device is in its on-state. When the external voltage is removed, the reverse current flows and the device returns to its off-state.

The V10150SHM3/4W is a versatile device with several application areas. It can be used in AC-to-DC converters and switch-mode power supplies, especially for applications that require high voltage and high power. It can also be used in device protection circuits, such as lightning and surge protectors, for added safety. The low reverse current leakage makes the V10150SHM3/4W especially suitable for these applications, as it can provide the needed protection without additional components.
