FGA20N120 IGBT Replacement Guide for 1200V Applications

The FGA20N120 is a 1200V, 20A Field Stop Trench IGBT primarily designed for high-voltage consumer electronics like induction heaters and microwave ovens Alldatasheet Onsemi.

Product Insights

Key Specifications: It features a low saturation voltage (1.6V typical) and a high collector current capability of 40A at 25°C Utmel Onsemi.
Applications: Its primary niche is soft-switching power conversion in induction cooking and high-efficiency inverter circuits Onsemi Onsemi.
Production Status: The original onsemi (Fairchild) part is Obsolete as of early 2021 Digikey Onsemi. This has shifted the market toward replacement series or specialized equivalents like the Toshiba GT40QR21 or IXYS IXYH20N120 series Digikey.

Market Trends

Transition to Wide Bandgap (WBG): While traditional IGBTs like the FGA20N120 are still used in legacy and cost-sensitive consumer goods, the broader power transistor market is shifting toward GaN and SiC technologies for higher efficiency and density, with the GaN market expected to see significant revenue growth through 2026 Precedenceresearch Fortunebusinessinsights.
Sourcing Strategy: Due to the obsolete status, current availability is limited to remaining stock or refurbished units from specialized B2B distributors.
