5KP43-B

Since its introduction in the early 1980s, the 5KP43-B transient voltage suppressor diode (TVS) has been a popular solution for protecting delicate electronic components and systems from electrical transients. Unlike other types of protection devices, the 5KP43-B is designed to protect against both electrical overvoltage and electrical fast transients (EFTs).

The 5KP43-B transient voltage suppressor diode (TVS) is manufactured with a silicone avalanche diode housed in a two-lead, axial package. The TVS diode utilizes multiple layers of polysilicon and a p-n junction breakdown structure to protect against overvoltage. When the diode is subject to an overvoltage, it will enter an active conduction state and the current will be diverted from the load to the diode, thus protecting the load from voltage overshoots.

In addition to overvoltage protection, the 5KP43-B also provides protection against electrical fast transients (EFTs). EFTs are high-frequency electrical spikes that can cause damage to sensitive electronic components. The 5KP43-B is designed to absorb and dissipate the energy from EFTs, thus preventing damage to the protected equipment.

The 5KP43-B transient voltage suppressor diode can be used in a variety of applications, including automotive, consumer electronics, industrial control, telecom, computers and peripherals. It is also suitable for a wide range of operating voltages, up to 6.5V. It can be used in both AC and DC circuits, providing reliable protection from overvoltages and transients.

In conclusion, the 5KP43-B transient voltage suppressor diode is a reliable and cost effective solution for protecting sensitive electronic components and systems from EFTs and overvoltages. Its small size and wide operating voltage range make it suitable for a variety of applications.
