The NTD4906NT4G is a dual N-channel enhancement-mode MOSFET from onsemi in SOIC-8, with each MOSFET rated at 30V drain-source voltage and 9.2A drain current with 26mOhm RDS(on) at VGS=10V (35mOhm at VGS=4.5V). The dual MOSFET configuration shares a common drain (pins 5-8, connected to the thermal tab), making it ideal for half-bridge and synchronous buck converter topologies where both MOSFETs connect to the same switching node. In a synchronous buck converter, MOSFET 1 is the high-side (control) switch and MOSFET 2 is the low-side (synchronous rectifier). The common drain minimizes parasitic inductance between the two MOSFETs, reducing ringing and EMI. The trench-gate technology achieves 26mOhm in the SOIC-8 footprint, which has thermal resistance of approximately 30C/W on a copper pour. At 5A per MOSFET, conduction loss is I2R = 25 x 0.026 = 0.65W per MOSFET, 1.3W total. The gate charge is 17nC at 4.5V per MOSFET, requiring a gate driver capable of 0.5-1A for 100kHz PWM operation. The independent gate pins (G1, G2) allow non-overlap (dead-time) control to prevent cross-conduction shoot-through. The 30V rating targets 3.3V, 5V, and 12V power supply rails.
