概述

Description

PESD3V3Z1BSFYL is a 3.3 V ESD protection diode from Nexperia’s PESD3V3 family. It is a single-line protection device placed between a 3.3 V I/O pin and ground to guard sensitive circuitry from electrostatic discharges and transient events. In normal operation it remains high-impedance, but when an ESD pulse occurs, it clamps the voltage to a safe level and shunts energy away from the protected IC. The device features ultra-low input capacitance to minimize impact on signal integrity and low leakage, and it comes in a tiny surface-mount, lead-free (RoHS) package suitable for compact boards. Typical applications include protecting 3.3 V microcontroller inputs, sensors, and other low-voltage interface lines (e.g., SPI, I2C, UART). For exact electrical specs—ESD rating, clamp voltage, capacitance, leakage, and breakdown—consult the PESD3V3Z1BSFYL datasheet. If your design requires a different standoff voltage or package, look for the corresponding variant in the PESD3V3 family.

Features

PESD3V3Z1BSFYL features (concise):
- 3.3 V working standoff voltage
- 1-channel ESD protection diode array for a single I/O line
- Very low input capacitance (sub-pF range) to minimize signal loading on high-speed lines
- Low leakage and fast response for effective, rapid protection
- Low clamping voltage during ESD events
- Ultra-compact package (SC-70/SOT-323 family footprint)
- RoHS-compliant and suitable for space-saving designs
- Operating temperature range typically around -40°C to +85°C (check datasheet for exact limits)
Note: For exact electrical specs and packaging details, please consult the official datasheet.

Package

SC-70-3 (SOT-323) 3-pin small SMD package.

Pinout

- Pin count: 3 pins
- Function: Single-channel 3.3 V ESD protection diode (TVS) array for one I/O line; clamps ESD surges to ground. It typically has one signal pin and two ground pins.

Manufacturer

Manufacturer: Nexperia.
What kind of company: A global semiconductor company that designs and manufactures discrete components, ESD protection diodes, logic devices, and MOSFETs. It originated from Philips Semiconductors/NXP and became an independent company in 2017, with headquarters in the Netherlands.

Application

3.3 V single-line ESD protection diode. Used to protect low-voltage data/control lines near connectors: USB, HDMI, MIPI-CSI/DSI, I2C/SPI/UART, and other 3.3 V IOs. Suitable for microcontrollers, sensors, displays, cameras, mobile/IoT, consumer electronics, automotive and industrial equipment. Low capacitance to preserve high-speed signal integrity.

Equivalent

PESD3V3Z1BSFYL is a 3.3V multi-line ESD protection diode array. To provide exact cross references, please confirm package type (e.g., SOT-23-6), number of channels, and whether vendors like ST, Onsemi, Littelfuse, or Bourns are acceptable.
