Diodes Incorporated HER105-T

Overview

HER105-T from Diodes Incorporated is a high-efficiency fast rectifier with 1 A, 400 V, axial through-hole rectifier package. It is used when a general rectifier is too slow but a low-leakage silicon rectifier is still preferred over a Schottky device.

In BOM review, HER105-T should be matched against switching power supplies, fast freewheel paths, snubber and clamp circuits, converter auxiliary rails, plus package marking, lifecycle status, and the electrical details that make this exact orderable part useful.

Technical Context

HER105-T is selected for rectification where standard rectifier speed may be too slow. It supports converter and clamp circuits that need a balance of blocking voltage, current, and recovery behavior.

Thermal layout and repetitive waveform stress are important because fast rectifiers can still dissipate substantial energy during forward conduction and reverse recovery.

Key Specifications

Pinout & Package

HER105-T uses axial through-hole rectifier package. Pin mapping, polarity, or item format should be matched to the exact board, fixture, or procurement requirement before replacement.

Key Features

• HER105-T is identified as a high-efficiency fast rectifier.
• 400 V voltage or operating class for the relevant circuit stress.
• 1 A current or output class, subject to package and thermal derating.
• axial through-hole rectifier package package or item format for procurement and assembly review.
• fast reverse-recovery behavior
• high-current rectification
• low leakage
• power-supply switching use

Applications

Equivalent & Alternatives

When evaluating HER105-T 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

HER105-T 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 high-efficiency fast rectifier production, repair, or lifecycle procurement.

Availability

HER105-T is available at Aetrix Electronics and suitable for switching power supplies, fast freewheel paths, snubber and clamp circuits, converter auxiliary rails requiring 1 A, 400 V, axial through-hole rectifier package 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 high-efficiency fast 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 HER105-T.

Manufacturer

Diodes Incorporated supplies rectifiers, Schottky diodes, SBR devices, protection products, transistors, MOSFETs, analog ICs, logic devices, and power-management semiconductors. HER105-T belongs to the Diodes Incorporated product family identified by its prefix and package suffix.

FAQ

What is HER105-T used for?

HER105-T is used for switching power supplies, fast freewheel paths, snubber and clamp circuits. In those circuits, HER105-T provides the high-efficiency fast rectifier function with 1 A, 400 V, axial through-hole rectifier package. The final selection should match the schematic role, operating stress, package footprint, and sourcing requirements.

What package or format does HER105-T use?

HER105-T uses axial through-hole rectifier package. This package or item format affects footprint, soldering, thermal behavior, polarity or pin mapping, and incoming inspection. When replacing HER105-T, the package code should be checked as carefully as the headline electrical rating.

What are the key design checks for HER105-T?

Key design checks for HER105-T 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 HER105-T be replaced by a similar part?

HER105-T 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 HER105-T may carry package, program, bin, or lifecycle details.

Why source HER105-T through Aetrix Electronics?

Sourcing HER105-T through Aetrix Electronics supports traceable procurement, scheduled delivery planning, BOM continuity assistance, and lifecycle availability coordination. This is useful when HER105-T is needed for production builds, repair lots, controlled alternates, or long-running equipment support.
