DESCRIPTION
The UTC 9N40 is an N-channel mode power MOSFET using
UTC’s advanced technology to provide customers with planar stripe
and DMOS technology. This technology specializes in allowing a
minimum on-state resistance and superior switching performance. It
also can withstand high energy pulse in the avalanche and
commutation mode.
The UTC 9N40 is universally applied in electronic lamp ballast
based on half bridge topology and high efficient switched mode
power supply.

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Repetitive Rating: Pulse width limited by maximum junction temperature.
3. L = 10.5mH, IAS = 9A, VDD = 90V, RG = 25Ω, Starting TJ = 25°C.
4. ISD ≤ 9A, di/dt ≤ 200A/µs, VDD ≤ BVDSS, Starting TJ = 25°C.
