SI4459ADY-T1-GE3 Description

Short technical summary and product information.

The SI4459ADY-T1-GE3 is a P-Channel enhancement mode MOSFET from Vishay Dale, manufactured using advanced MOSFET technology. It is designed for high efficiency power switching applications. With a drain-to-source voltage rating of 30 V and a continuous drain current of 29 A at 25°C case temperature, this device delivers low on-resistance of 5 mOhm (maximum) at 15 A and 10 V gate drive. The gate threshold voltage is 2.5 V maximum at 250 µA drain current. The total gate charge is 195 nC at 10 V, and input capacitance is 6000 pF at 15 V Vds, indicating moderate switching speed capability.

 

The MOSFET is housed in an 8-SOIC surface mount package with a width of 3.90 mm. It supports a maximum power dissipation of 3.5 W at ambient temperature and 7.8 W at case temperature. The operating junction temperature range is -55°C to 150°C, suitable for automotive and industrial environments. This device is intended for applications such as DC-DC converters, load switching, and power management circuits where a P-Channel MOSFET is required for high-side switching.
