PESD5V0C1USFYL

PESD5V0C1USFYL is a single-line electrostatic discharge (ESD) protection diode from the PESD5V0C1 family (Nexperia). It protects a 5 V signal line from ESD events, keeping sensitive downstream circuitry safe.
Key points:
- One-channel, low-capacitance ESD protector designed for 5 V lines
- Very low input capacitance (typical around 1 pF) to minimize signal distortion on high-speed lines
- Compact USFYL package for surface-mount applications
- Provides clamping during ESD events to protect ICs; typically supports industry-standard discharge levels per IEC 61000-4-2 variants
- Suitable for USB, microcontroller I/O, camera/sensor interfaces, and other 5 V signal lines
How to use:
- Place the device close to the protected connector/entry point, between the signal line and ground
- Follow the datasheet for exact pinout and orientation
For precise electrical specs and packaging details, consult the PESD5V0C1USFYL datasheet.

PESD5V0C1USFYL features (concise):
- 1-channel ESD protection diode array for a single 5 V data line
- Working voltage: 5 V
- Ultra-low capacitance (typical ~0.5–2 pF) to minimize signal distortion

- Function: Single-line ESD protection diode array; clamps ESD to ground on one I/O line with a 5 V working voltage and low capacitance.

- Manufacturer: Nexperia
- What kind of company: Nexperia is a global semiconductor company (based in the Netherlands) that designs and manufactures discrete semiconductors and protection devices, including ESD protection diodes.

PESD5V0C1USFYL is a 1-channel 5 V ESD protection diode array. It protects sensitive IO pins from electrostatic discharges on lines up to 5 V. Common applications: USB data lines, microcontroller I/O, serial interfaces (I2C, SPI, UART), camera/display interfaces (LCDs, image sensors), keypad/sensor inputs, and other portable/consumer-electronics I/O. Typically placed near connectors on the PCB to provide fast clamping with low input capacitance to preserve signal integrity.

It comes in a USON-6 (USF) package—an ultra‑small 6‑pin SMD package.
