Part Number | 1N4448 | |
Description | 150mA, 100V, FAST SWITCHING DIODE | |
Manufacturers | Diodes Incorporated | |
Logo | ||
The 1N4448 is a small signal fast switching diode. Features: 1. Fast Switching Speed 2. General Purpose Rectification 3. Silicon Epitaxial Planar Construction Advantages: 1. Its small size and low forward voltage drop make it suitable for use in a wide range of applications, including power supplies, signal processing, and RF circuits. 2. The diode has a fast switching speed, making it ideal for applications that require fast response times. Disadvantages: 1. The 1N4448 has a relatively low maximum reverse voltage rating of 100 V, which may not be sufficient for some applications. 2. The diode has a relatively low maximum forward current rating of 150 mA, which may not be suitable for high power applications. 3. The diode can experience thermal runaway if operated at high current levels or with insufficient heat sinking. There is a preview and 1N4448 download ( pdf file ) link at the bottom of this page.
