Product details

Active production, 100 V N-channel in TO-220AB

The TO-220AB through-hole package suits bolted-down heatsink mounting in power supplies, DC-DC converters, and inverter legs where board-level thermal management is the primary constraint.

Total gate charge is 255 nC at 10 V, with an input capacitance of 9500 pF at 50 V drain bias. For a 100 kHz hard-switched application, the average gate-drive current required is 25.5 mA — within the capability of a standard totem-pole driver, but the peak current during the Miller plateau demands a driver with at least 2 A source/sink capability to keep switching losses under control.

Frequently asked questions

What is the Rds(on) of IRF100B201?

The maximum on-resistance is 4.2 mOhm at 115 A drain current with 10 V gate-to-source drive. This is the conduction-loss figure used for heatsink sizing in high-current paths.

What is the gate charge of IRF100B201?

This value determines the average gate-drive current needed at the target switching frequency and the peak current capability required from the gate driver.

Can IPD50R950CEAUMA1 replace IRF100B201?

No. The IPD50R950CEAUMA1 is a 500 V CoolMOS CE part with 950 mOhm Rds(on) and 4.3 A continuous drain current — a different voltage class and current rating. It is not a functional replacement for the 100 V, 192 A IRF100B201.
