Description
Overview
The ESD5Z5V0C is a compact unidirectional TVS/ESD protection diode designed to protect sensitive electronic circuits from electrostatic discharge and transient voltage events. It features a 5 V reverse standoff voltage and a fast response time, making it suitable for protecting signal and I/O lines.
The device is housed in the space-saving SOD-523 SMD package, making it particularly suitable for compact PCB designs where board space is limited. The exact electrical ratings can vary between manufacturers using the ESD5Z5V0C designation, so the specifications below correspond to the 9.4 A / 11.6 V version matching your supplied description.

The 9.4 A / 18.6 V rating is specified for the 8/20 µs surge waveform; the 11.6 V clamping specification is associated with a lower 5 A test current. These values should not be interpreted as 11.6 V clamping at 9.4 A.
ESD Protection
The device is intended for protection against transient events such as:
- Electrostatic discharge
- Electrical transients
- Surge events on signal lines
- Switching-induced voltage spikes
Some ESD5Z5V0C/ESD5Z5V0 variants specify IEC 61000-4-2 Level 4 protection, but the exact ESD rating depends on the manufacturer and variant.
Applications
- USB and communication interfaces
- Microcontroller I/O protection
- Sensor interfaces
- Digital signal lines
- Portable electronics
- Consumer electronics
- Industrial control interfaces
- Data and communication equipment
- General-purpose ESD protection
What’s Included
- 1 × ESD5Z5V0C 5 V TVS/ESD Protection Diode
- Package: SOD-523
- SMD / Surface Mount
Notes
- ESD5Z5V0C is a TVS/ESD protection diode, not a conventional signal or rectifier diode.
- It is unidirectional, so polarity must be observed during PCB assembly.
- 11.6 V is the clamping voltage at the specified test current, not the normal operating voltage.
