Nexperia USA Inc. PESD5V0L1BA,115

Overview

PESD5V0L1BA,115 from Nexperia USA Inc. is a bidirectional ESD protection diode designed to protect one signal line from electrostatic discharge, surge pulses, and other transient voltage events. The device provides 5V reverse standoff voltage, 500W peak pulse power capability, 30kV IEC 61000-4-2 contact discharge protection, and a compact SOD323 package for space-constrained PCB designs.

As part of the Nexperia ESD protection diode portfolio, PESD5V0L1BA,115 combines bidirectional line protection, low leakage current, surge capability, and small-package integration for digital and mixed-signal interfaces. For engineers reviewing the PESD5V0L1BA,115 datasheet, PESD5V0L1BA,115 pinout, PESD5V0L1BA,115 application, or PESD5V0L1BA,115 equivalent, this device is widely used in computers and peripherals, communication systems, audio/video equipment, data lines, interface ports, and general-purpose signal-line protection circuits.

Technical Context

In interface protection circuits, PESD5V0L1BA,115 operates as a bidirectional TVS/ESD diode connected between the protected signal line and ground or between two line nodes, depending on the system protection topology. Its bidirectional behavior allows it to protect lines where signal polarity can swing both positive and negative with respect to ground.

The device is designed for one bidirectional data line and provides transient clamping during ESD, EFT, and surge events. With a 5V reverse standoff voltage and 7V to 8.2V breakdown voltage range, it is suitable for protecting low-voltage interface signals while remaining inactive during normal operation.

PESD5V0L1BA,115 is commonly placed close to external connectors, exposed signal interfaces, board-to-board ports, communication lines, peripheral connections, and audio/video input-output paths to reduce transient energy before it reaches sensitive IC pins.

Key Specifications

Pinout & Package

The PESD5V0L1BA,115 pinout uses a 2-lead SOD323 package. Pin 1 is K1 and pin 2 is K2, forming a bidirectional protection structure for one protected line. The small SOD323 outline supports compact placement near external connectors and exposed signal traces.

For PCB implementation, the device should be placed as close as possible to the input terminal or connector. The protected trace should be short, the transient return path should be minimized, and ground-plane or ground-via connections should be used where possible to improve ESD and surge suppression performance.

Key Features

• Bidirectional ESD protection for one signal line.
• 5V reverse standoff voltage for low-voltage interface protection.
• 500W peak pulse power capability for non-repetitive surge events.
• IEC 61000-4-2 ESD protection up to 30kV contact discharge and 15kV air discharge.
• IEC 61000-4-5 surge support with 15A peak pulse current.
• Low 0.01µA typical leakage current reduces loading on protected lines.
• Compact SOD323 / SC-76 package supports dense PCB layouts.
• Suitable for data lines, communication systems, computer peripherals, and A/V equipment.

Applications

Equivalent & Alternatives

When evaluating PESD5V0L1BA,115 equivalent devices, engineers should compare reverse standoff voltage, breakdown voltage, clamping voltage, capacitance, leakage current, ESD rating, surge-current capability, package style, and single-line bidirectional protection requirements.

Compared with PESD5V0L1BSF, PESD5V0L1BA,115 is optimized for designs using the SOD323 / SC-76 footprint and one-line bidirectional ESD protection. PESD5V0L1BA,115 vs SMF5.0CA selection depends on PCB area, capacitance tolerance, surge-power requirement, clamping voltage, leakage-current limit, and interface-speed requirement.

Quality

PESD5V0L1BA,115 should be sourced as original Nexperia components through traceable and controlled supply channels. Quality verification procedures may include package inspection, marking-code validation, solderability testing, leakage-current testing, breakdown-voltage verification, clamping-performance review, and incoming inspection according to interface-protection production requirements.

Because the device is used on exposed signal lines, connector-side placement, short transient paths, solid ground routing, low-inductance PCB loops, and proper ESD return-path design help maintain protection performance and long-term reliability. Traceable sourcing supports industrial manufacturing quality and reduces counterfeit supply-chain risk.

Availability

PESD5V0L1BA,115 available at Aetrix Electronics and suitable for computers and peripherals, communication systems, audio/video equipment, data-line protection, embedded interfaces, and compact low-voltage signal-protection applications requiring stable component supply and repeatable production support.
