ON SEMICONDUCTOR

ONSEMI

Diodes, transistors and circuit protection

About the manufacturer

onsemi was formed in the United States in 1999 when Motorola spun off its standard semiconductor-products business as ON Semiconductor. A major milestone was its acquisition of Fairchild Semiconductor in 2016, which strengthened its power-electronics expertise. The company adopted the onsemi name in 2021 to reflect its focus on intelligent power and sensing. It develops technologies for automotive systems, industrial automation and energy conversion, including silicon-carbide power devices.

The main technical solutions associated with ONSEMI include power MOSFETs and transistors, diodes and rectifiers and image sensors. Discrete components provide rectification, transient protection, and signal or power switching. Families differ in recovery speed, forward voltage, conduction losses and thermal behavior. A broad choice of SMD packages supports integration into compact PCB designs.

Applications

ONSEMI solutions are relevant to applications where component characteristics must be matched to the final equipment:

• switch-mode power supplies
• rectifier circuits
• surge protection
• load switching
• industrial electronics
• portable equipment

ONSEMI products available from Maritex

The Maritex catalogue range listed under ONSEMI focuses on the following product groups: power MOSFETs and transistors; diodes and rectifiers; image sensors. Individual models may differ in electrical specifications, mechanical construction and integration requirements.

Available product groups include:

• power MOSFETs and transistors
• diodes and rectifiers
• image sensors
• power-management ICs

Selection should compare reverse or blocking voltage, continuous and surge current, thermal properties and package. For protection parts, pulse ratings, parasitic capacitance and the requirements of the protected interface also matter. The exact variant should always be selected using its full part number and model-specific documentation.
