1N4991 Description

Short technical summary and product information.

The 1N4991 is a Transient Voltage Suppressor (TVS) diode from MSC, designed for circuit protection applications.

This component features RoHS3 compliance, indicating adherence to specific environmental standards. It also has a Moisture Sensitivity Level (MSL) of 1, meaning it has unlimited shelf life under standard conditions. The REACH status is unaffected, suggesting it does not contain substances of concern under the REACH regulation.

As a TVS diode, the 1N4991 is intended to protect sensitive electronic components from transient voltage events, such as electrostatic discharge (ESD) and lightning-induced surges. Its specific electrical characteristics, such as breakdown voltage, clamping voltage, and peak pulse current, would typically be detailed in the manufacturer's datasheet, enabling engineers to select it for appropriate protection circuits.

Further details regarding package type, mounting, and specific electrical parameters are essential for design integration and should be sourced from the official product documentation.
