CSD18512Q5BT Description

Short technical summary and product information.

The CSD18512Q5BT is a single N-channel MOSFET manufactured by Texas Instruments. It is designed for high-current switching applications, offering a drain-to-source voltage rating of 40V and a continuous drain current of 211A at Tc.

 

The device features a maximum on-resistance of 1.6mOhm at Id=30A and Vgs=10V, and is available with drive voltages of 4.5V and 10V. The maximum gate threshold voltage is 2.2V at Id=250µA, and the maximum gate-source voltage is ±20V. It has an input capacitance of 7120pF at Vds=20V and a total gate charge of 98nC at Vgs=10V.

 

Power dissipation is rated at 139W at Tc, with an operating junction temperature range of -55°C to 150°C. The component is offered in an 8-PowerTDFN surface-mount package, with a supplier package designator of 8-VSON-CLIP (5x6).

 

The combination of low on-resistance, high current capability, and standard gate drive voltages makes the CSD18512Q5BT suitable for power conversion and load switching circuits. The surface-mount package supports compact board designs in commercial and industrial electronics.
