概述
Description
The SMAJ5.0A-TR is a surface-mount TVS diode designed for transient voltage suppression in electronic circuits. It protects sensitive components from voltage spikes (e.g., ESD, lightning surges) by clamping excess voltage to a safe level.
Key Features:
- Breakdown Voltage: 6.4V (min)
- Peak Pulse Power: 400W (8/20µs waveform)
- Low Clamping Voltage: 9.2V at 1A
- RoHS Compliant & SMA Package
Applications:
- ESD protection for USB, HDMI, or data lines
- Surge suppression in power supplies, automotive systems, and telecom equipment
The "-TR" suffix indicates it comes on a tape-and-reel for automated assembly. Its compact size and robust performance make it ideal for space-constrained designs requiring reliable overvoltage protection.
For detailed specs, refer to the manufacturer’s datasheet.
