Nexperia USA Inc. PESD1USB3B/CX

Overview

PESD1USB3B/CX from Nexperia USA Inc. is an ESD protection diode / diode array with USB 3.x interface protection class, ultra-small leadless protection package. It protects exposed lines by clamping transient energy while keeping normal signal capacitance and leakage within interface limits.

For engineers reviewing the PESD1USB3B/CX datasheet, PESD1USB3B/CX pinout, PESD1USB3B/CX application, or PESD1USB3B/CX equivalent, the most useful checks are USB 3.x interface protection class, ultra-small leadless protection package, USB and high-speed data ports, mobile connectors.

Technical Context

PESD1USB3B/CX protects sensitive lines by clamping fast electrostatic or surge transients. Working voltage, capacitance, and clamping behavior must match the protected interface.

For USB, data, and connector protection, PESD1USB3B/CX should be placed with short return paths and reviewed for signal integrity because package inductance and capacitance affect high-speed performance.

Key Specifications

Pinout & Package

PESD1USB3B/CX uses ultra-small leadless protection package. Pin mapping, polarity, or item format should be matched to the exact board, fixture, or procurement requirement before replacement.

Key Features

• PESD1USB3B/CX is identified as a ESD protection diode / diode array.
• USB 3.x interface protection class voltage or operating class for the relevant circuit stress.
• surge and ESD pulse current dependent on standard current or output class, subject to package and thermal derating.
• ultra-small leadless protection package package or item format for procurement and assembly review.
• low capacitance for high-speed lines
• IEC-style ESD transient protection
• compact rail or line clamping
• Low capacitance helps protect fast data lines with less signal loading.
• ESD pulse rating, working voltage, and clamping behavior must fit the interface.

Applications

Equivalent & Alternatives

When evaluating PESD1USB3B/CX equivalent devices, compare voltage rating or operating class, current or output capability, package and footprint, pin mapping or polarity, thermal behavior, qualification suffix, lifecycle and sourcing status. A similar family name is not enough when the board depends on timing, leakage, firmware, optical output, or protection behavior.

Quality

PESD1USB3B/CX should be sourced as original Nexperia USA Inc. material through traceable and controlled supply channels. Quality verification may include package inspection, line-to-ground leakage screening, capacitance-sensitive application review, marking verification, and solderability testing, along with incoming inspection suited to ESD protection diode / diode array production, repair, or lifecycle procurement.

Availability

PESD1USB3B/CX is available at Aetrix Electronics and suitable for USB and high-speed data ports, mobile connectors, industrial I/O lines, communication interface protection requiring USB 3.x interface protection class, ultra-small leadless protection package in a controlled BOM or repair program.

FAQ

What is PESD1USB3B/CX used for?

PESD1USB3B/CX is used for USB and high-speed data ports, mobile connectors, industrial I/O lines. In those circuits, PESD1USB3B/CX provides the ESD protection diode / diode array function with USB 3.x interface protection class, ultra-small leadless protection package. The final selection should match the schematic role, operating stress, package footprint, and sourcing requirements.

What interface details matter for PESD1USB3B/CX?

PESD1USB3B/CX should be selected by working voltage, capacitance, leakage, clamping voltage, package inductance, and the protected line type. For USB or other fast interfaces, PESD1USB3B/CX must protect against ESD while preserving signal integrity.

Where should PESD1USB3B/CX be placed on a PCB?

PESD1USB3B/CX should normally sit close to the connector or exposed line with a short, low-inductance return path. Placement affects clamping performance, so PESD1USB3B/CX is not just an electrical selection but also a layout-sensitive protection component.

Can PESD1USB3B/CX be replaced by a similar part?

PESD1USB3B/CX can be compared with similar family members only after electrical limits, package, orientation, qualification suffix, timing or leakage behavior, and approved-source rules are reviewed. A similar name alone is not enough because PESD1USB3B/CX may carry package, program, bin, or lifecycle details.

Why source PESD1USB3B/CX through Aetrix Electronics?

Sourcing PESD1USB3B/CX through Aetrix Electronics supports traceable procurement, scheduled delivery planning, BOM continuity assistance, and lifecycle availability coordination. This is useful when PESD1USB3B/CX is needed for production builds, repair lots, controlled alternates, or long-running equipment support.
