Diodes Incorporated PD3S220LQ-7

Overview

PD3S220LQ-7 from Diodes Incorporated is a 2 A surface-mount Schottky barrier rectifier with 2 A, 20 V, PowerDI323. It targets low forward loss in low-voltage power paths, where a standard silicon rectifier would waste more voltage and heat.

PD3S220LQ-7 is most relevant to battery rails, portable DC-DC converters, reverse-protection paths, compact rail steering, where the surrounding circuit depends on the same rating profile, footprint, thermal behavior, and sourcing continuity.

Technical Context

PD3S220LQ-7 uses Schottky behavior for low forward voltage and fast switching. That makes it valuable in low-voltage rails where every millivolt of conduction loss can affect heat or output margin.

Schottky leakage rises with voltage and temperature, so reverse-bias stress, hot leakage, copper area, and surge exposure should be reviewed together before changing the diode.

Key Specifications

Pinout & Package

Applications

Equivalent & Alternatives

When evaluating PD3S220LQ-7 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

PD3S220LQ-7 should be sourced as original Diodes Incorporated material through traceable and controlled supply channels. Quality verification may include package inspection, marking verification, polarity or pinout review, solderability testing, leakage or continuity checks, and reel label verification, along with incoming inspection suited to 2 A surface-mount Schottky barrier rectifier production, repair, or lifecycle procurement.

Availability

PD3S220LQ-7 is available at Aetrix Electronics and suitable for battery rails, portable DC-DC converters, reverse-protection paths, compact rail steering requiring 2 A, 20 V, PowerDI323 in a controlled BOM or repair program.

Supply support may include scheduled delivery planning, volume procurement support, BOM continuity assistance, traceable sourcing management, and lifecycle availability coordination for manufacturers, repair teams, contract manufacturers, and engineering buyers managing 2 A surface-mount Schottky barrier rectifier demand.

For production deployment, confirming package fit, pin mapping or polarity, electrical rating, temperature margin, lifecycle status, approved manufacturer identity, and sourcing continuity helps reduce qualification risk for PD3S220LQ-7.

Manufacturer

Diodes Incorporated supplies rectifiers, Schottky diodes, SBR devices, protection products, transistors, MOSFETs, analog ICs, logic devices, and power-management semiconductors. PD3S220LQ-7 belongs to the Diodes Incorporated product family identified by its prefix and package suffix.

FAQ

What is PD3S220LQ-7 used for?

PD3S220LQ-7 is used for battery rails, portable DC-DC converters, reverse-protection paths. In those circuits, PD3S220LQ-7 provides the 2 A surface-mount Schottky barrier rectifier function with 2 A, 20 V, PowerDI323. The final selection should match the schematic role, operating stress, package footprint, and sourcing requirements.

What package or format does PD3S220LQ-7 use?

PD3S220LQ-7 uses PowerDI323. This package or item format affects footprint, soldering, thermal behavior, polarity or pin mapping, and incoming inspection. When replacing PD3S220LQ-7, the package code should be checked as carefully as the headline electrical rating.

What are the key design checks for PD3S220LQ-7?

Key design checks for PD3S220LQ-7 include voltage margin, current or output load, temperature rise, pinout or polarity, package fit, lifecycle status. These checks help prevent a visually similar part from changing circuit behavior or assembly reliability.

Can PD3S220LQ-7 be replaced by a similar part?

PD3S220LQ-7 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 PD3S220LQ-7 may carry package, program, bin, or lifecycle details.

Why source PD3S220LQ-7 through Aetrix Electronics?

Sourcing PD3S220LQ-7 through Aetrix Electronics supports traceable procurement, scheduled delivery planning, BOM continuity assistance, and lifecycle availability coordination. This is useful when PD3S220LQ-7 is needed for production builds, repair lots, controlled alternates, or long-running equipment support.
