PESD5V0F1BL-QYL

PESD5V0F1BL-QYL is a single-line electrostatic discharge (ESD) protection diode from Nexperia’s PESD family. It provides fast, low-capacitance protection for sensitive I/O lines with a nominal stand-off voltage around 5 V, helping to clamp ESD pulses to safe levels and divert surge current to ground.
Key points:
- Purpose: Protect data/IO lines (USB, microcontroller I/O, displays, etc.) from ESD without adding significant loading.
- Voltage/capacitance: Designed for 5 V logic while maintaining very low capacitance to preserve high-speed signal integrity.
- Packaging: Small SMT package; “QYL” denotes the specific package variant; refer to the datasheet for exact footprint.
- Usage: Connect between the protected signal line and ground; follow the device orientation and pinout in the datasheet.
- Selection: Choose when you need ESD protection on 5 V logic lines and want minimal impact on signal timing and integrity.
Note: For exact electrical specs, package details, and whether this variant is unidirectional or bidirectional, consult the PESD5V0F1BL-QYL datasheet.
