Substitute Part Grouping Explanation

Substitution of the NGD8209NT4G is determined by strict equivalence of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Voltage - Collector Emitter Breakdown (Max): 445 V
• Current - Collector (Ic) (Max): 12 A
• Current - Collector Pulsed (Icm): 30 A
• Vce(on) (Max) @ Vge, Ic: 2.3 V @ 4.5 V, 10 A
• Power - Max: 94 W
• Package / Case: TO-252-3, DPAK (Surface Mount)
• Input Type: Logic
• Operating Temperature Range: -55°C to 175°C (TJ)

The substitute part LGD8209TI is identified as a direct equivalent based on matching electrical ratings and identical package configuration. Both components are manufactured by Littelfuse Inc. and share the same functional classification as logic-input IGBTs within the 410 V / 12 A / 125 W specification band.
