ESD3Z5V0 5V Unidirectional TVS Diode / ESD Protection (SOD-323)

Protect sensitive 5V digital lines, microcontrollers, and low-power DC rails from high-energy electrostatic discharge (ESD) with the ESD3Z5V0 unidirectional TVS diode. Exposure to human contact, cable insertion, or stray voltage transients can easily cause catastrophic failure in vulnerable silicon logic. Designed specifically for 5V systems, the ESD3Z5V0 stays completely passive under normal operating conditions and reacts in sub-nanoseconds during an overvoltage event, clamping destructive voltage spikes and diverting surge currents safely to ground.

With a 5V reverse standoff voltage ($V_{RWM}$) and high ESD immunity (compliant with IEC 61000-4-2 Level 4 standards), it delivers robust localized defense directly at input connectors, reset lines, and GPIO pins. Its compact SOD-323 surface-mount footprint makes it easy to integrate into space-constrained custom PCBs, drone electronics, and IoT edge devices.

Key Features:

• 5V Logic Shielding: Engineered specifically for standard 5V DC supply lines, sensor headers, and GPIO pins.

• Ultra-Fast ESD Clamping: Sub-nanosecond response time neutralizes dangerous static charges before they can reach delicate IC inputs.

• Unidirectional Protection: Optimized for DC lines, clamping positive transients and blocking reverse voltage.

• Compact SOD-323 Package: Small surface-mount footprint allows precise placement right next to vulnerable connector pins.
