Description

SI4943CDY-T1-GE3 is a Vishay Siliconix N-channel enhancement-mode MOSFET. It is a small, high-efficiency power switch device used in low-voltage power electronics.
Key points:
- N-channel MOSFET designed for switching and amplification in DC-DC converters, load switches, motor drivers, and similar applications.
- Packaged in a compact surface-mount variant (GE3 code denotes a specific assembly/package option; see datasheet for exact pinout).
- Offers low on-resistance and fast switching characteristics to improve efficiency; suitable for logic-level gate drive in many designs.
- RoHS-compliant and suitable for rugged switching performance (check exact avalanche, thermal, and safe-operating-area specs in the datasheet).
Note:
Exact electrical specs (VDS, ID, RDS(on), gate charge), pinout, thermal limits, and packaging details vary by variant. Always consult the official datasheet for SI4943CDY-T1-GE3 to obtain the precise numbers and application guidance.

Package

D2PAK (TO-263) surface-mount package (3 leads plus center tab).

Pinout

- Pin count: 8 pins
- Function: Dual N-channel enhancement-mode MOSFETs in one package (two MOSFETs for power-switching/power-management applications).

Manufacturer
