1N4978US Description

Short technical summary and product information.

The 1N4978US from Microsemi Corporation is a single Zener diode designed for voltage regulation applications. This component is RoHS3 Compliant and has a Moisture Sensitivity Level (MSL) of 1 Unlimited, indicating it is not sensitive to moisture and has an indefinite shelf life under recommended storage conditions.

The REACH status is listed as Unaffected. As a Zener diode, its primary function is to maintain a stable voltage across its terminals when reverse biased beyond its breakdown voltage. This makes it suitable for voltage reference circuits, voltage clamping, and surge protection.

Further specifications such as Zener voltage, power dissipation, and tolerance would be required for detailed application design. The component falls under the Discrete Semiconductor Products category, specifically within the Diodes - Zener - Single subcategory.
