Product details

620 V N-channel in a TO-220FP — primary-side switch for offline supplies

Drive voltage is specified at 10 V for the rated Rds(on); the threshold voltage maximum of 4.5 V at 100 µA means a standard 12 V gate drive from a PWM controller or driver IC will fully enhance the channel. The ±30 V maximum gate-source rating provides margin against ringing on the gate node in layouts with long traces.

Package and mounting — TO-220FP, no isolation hardware required

The TO-220 Full Pack (TO-220FP) is a fully molded through-hole package with the metal tab encapsulated in epoxy. Maximum power dissipation is 30 W at case temperature, which sets the heatsink sizing requirement for continuous operation.

Lifecycle — active, no end-of-life concern

For new designs, the active lifecycle removes the risk of a mid-production EOL notice on this specific order code.
