SI4202DY-T1-GE3

SI4202DY-T1-GE3 is a dual N-channel enhancement-mode MOSFET in a compact T1 package, intended for power-switching in DC-DC converters and load-switch circuits. It provides two MOSFETs in one device, helping save board space and simplify layouts for synchronous buck regulators, high/low-side switches, motor drivers, and LED drivers.
Key points to know:
- It contains two N-channel MOSFETs; exact pinout and whether drains or sources are common depend on the specific variant.
- Performance (Vds, Id, Rds(on), Vgs(th), Qg) and recommended operating conditions vary by revision; consult the official datasheet for precise numbers.
- Packaging: T1 is a small, surface-mount package; GE3 denotes RoHS-compliant/lead-free processing and a specific revision.
How to use:
- Drive gates with voltages within Vgs(max) as specified.
- Plan for proper heat dissipation and account for body-diodes in switching apps.
- Verify pinout and wiring against the datasheet for your exact board layout.
For exact electrical specs, pinout, and thermal data, consult the SI4202DY-T1-GE3 datasheet from the manufacturer.

Here are the common features of SI4202DY-T1-GE3 (dual N-channel MOSFET pair in one package):
- Dual N-channel enhancement-mode MOSFETs in a single package
