Product Description

Product Description

Surface mount fast switching diode 1N4148W
Belongs to small-signal diodes (also known as signal diodes), specifically designed for fast switching applications in low-power electronic circuits.
 

Features

- For surface mounted applications
· Glass Passivated Chip Junction
- Fast reverse recovery time
- Ideal for automated placement
- Lead free in comply with EU RoHS 2011/65/EU directives

Applications

• High-Speed Signal Circuits: Used in data communication systems (e.g., USB, HDMI) for signal clamping or protection.
• Switching Power Supplies: Assists in snubber circuits or voltage regulation due to fast switching.
• Consumer Electronics: Integrates into smartphones, tablets, and wearables for compact signal processing.
• Analog/Digital Circuits: Functions as a voltage limiter, rectifier, or logic-level translator in mixed-signal designs.
