Description
The SMAJ5.0A is a 5.0V unidirectional TVS diode designed for transient voltage suppression in electronic circuits. It protects sensitive components from voltage spikes (e.g., ESD, lightning) by clamping excess voltage to a safe level.
Key Features:
- Standoff Voltage (VWM): 5.0V
- Breakdown Voltage (VBR): 6.4V (min)
- Peak Pulse Current (IPP): 9.2A (8/20µs)
- Low Clamping Voltage: Fast response (<1ps)
Applications:
- Consumer electronics (USB, HDMI)
- Automotive systems
- Industrial controls
Package: DO-214AC (SMA) for surface-mount assembly.
The SMAJ5.0A is part of the SMAJ series by Littelfuse (or similar manufacturers), offering robust surge protection in compact form.
