Categories: Single Zener Diodes
Quality Control: Learn More
Microchip Technology 1N4957US is a 5W Zener diode featuring a 9.1V nominal breakdown voltage with a ±5% tolerance. This component is designed for surface mount applications, housed in a D-5B (SQ-MELF, E) package. It exhibits a maximum forward voltage of 1.5V at 1A and a reverse leakage current of 25 µA at 6.9V. The Zener impedance at the test current is a maximum of 2 Ohms. Operating across a temperature range of -65°C to 175°C, this diode is suitable for power regulation and voltage clamping applications in automotive, industrial, and consumer electronics sectors.
