PESD5V0C1USFYL

PESD5V0C1USFYL is a 5V electrostatic discharge (ESD) protection device (TVS/diode array) in a tiny USFYL package. It protects a single data/IO line from ESD strikes by clamping surges to safe levels and shunting current to ground, with very fast response and low added capacitance.
Key points:
- Function: protect 5V logic/data lines from ESD events
- Voltage: nominal standoff around 5.0 V
- Package: ultra-compact USFYL
- Characteristics: low leakage, very fast clamping, low line capacitance to preserve signal integrity
- Configuration: typically used for a single line (check datasheet for exact pinout and bidirectional vs. unidirectional variant)
Typical applications:
- USB, I2C/SPI/data interfaces, microcontroller inputs, audio jacks, and other 5V logic lines requiring ESD protection near connectors.
How to use:
- Place between the signal line and ground close to the connector or entry point; select the appropriate variant (bidirectional or unidirectional) per your signal type. Consult the datasheet for exact pinout, ratings, and layout guidelines.

PESD5V0C1USFYL is a 5 V single-channel ESD protection diode network in a tiny USFYL package. Key features:
- 5 V working standoff (protects low-voltage I/O lines)
- 1-channel ESD protection diode array (unidirectional)
- Very low input capacitance (typically sub-pF to ~1 pF per line) for minimal signal impact
- Low leakage during normal operation
- Fast ESD response and clamping per industry standards (IEC/IEC61000-4-2 compatible)
- Small, lead-free, halogen-free USFYL package; RoHS compliant
- Suitable for protecting high-speed interfaces and data lines (e.g., USB, CAN, I2C, etc.)

SOT-23-3 package (SC-70 style, 3-pin).

- Pin count: 6 pins (USF package)
- Function: 5 V ESD protection diode array (TVS) with multiple channels (typ. 4 data lines) sharing a common ground to clamp ESD surges and protect high-speed interfaces.

- Manufacturer: Nexperia.
- What kind of company: A global semiconductor company that designs and manufactures discrete devices, logic, MOSFETs, and protection components (including ESD protection diodes). It originated from Philips/NXP’s semiconductor business and was spun off as a standalone company, headquartered in the Netherlands.

Application areas: ESD protection for 5V data lines and I/O. Suitable for USB interfaces (USB 2.0/3.0), microcontroller peripherals, sensors, and other 5V digital lines. Ideal for handheld and consumer electronics, wearables, and small-form-factor boards where low-capacitance protection preserves signal integrity near connectors or I/O pins.
