SSM1N45B
450V N-Channel MOSFET
General Description
Features
These N-Channel enhancement mode power field effect
transistors are produced using Fairchild’s proprietary,
planar, DMOS technology.
This advanced technology has been especially tailored to
minimize on-state resistance, provide superior switching
performance, and withstand high energy pulse in the
avalanche and commutation mode. These devices are well
suited for electronic ballasts based on half bridge
configuration.

Notes:
1. Repetitive Rating : Pulse width limited by maximum junction temperature
2. L = 75mH, IAS = 1.6A, VDD = 50V, RG = 25 Ω, Starting TJ = 25°C
3. ISD ≤ 0.5A, di/dt ≤ 300A/µs, VDD ≤ BVDSS, Starting TJ = 25°C
4. Pulse Test : Pulse width ≤ 300µs, Duty cycle ≤ 2%
5. Essentially independent of operating temperature
6. a) Reference point of the RθJL is the drain lead
b) When mounted on the minimum pad size recommended (PCB Mount)
(RθJA is the sum of the junction-to-case and case-to-ambient thermal resistance. RθCA is determined by the user’s board design)
