TPSMB20A

Product Overview

The TPSMB20A belongs to the category of transient voltage suppressor (TVS) diodes. These diodes are used to protect sensitive electronic components from voltage spikes and transients. The TPSMB20A is designed to provide robust overvoltage protection for a wide range of applications. Its characteristics include high surge capability, low clamping voltage, and fast response time. The diode is typically available in a package that allows for easy installation on printed circuit boards. It is an essential component for safeguarding electronic circuits from voltage surges and transients.

Package: The TPSMB20A is commonly available in a DO-214AA (SMB) package, which is a surface-mount package.

Essence: The essence of the TPSMB20A lies in its ability to rapidly clamp transient voltages to a safe level, thereby protecting downstream components.

Packaging/Quantity: The TPSMB20A is often supplied in reels or tubes, with quantities varying based on manufacturer and distributor specifications.
