defined as the solder mounting surface of the drain pins. RӨJC is guaranteed by design while RӨJA is determined by the
user’s board design.

The FDZ2040L is a low RDS(ON) P-Channel load switch packaged in space saving 0.8x0.8 WL-CSP.
The core of the device is a 80mΩ P-Channel MOSFET and capable of functioning over a wide input operating range of 1.6-4 V.
Applications Information
FDZ2040L Integrated Load Switch
Operation Description
Figure 21. Typical Application
Input Capacitor
To reduce device inrush current effect, a 0.1uF ceramic capacitor, CIN is recommended close to VIN pin. A higher value of CIN
can be used to further reduce the voltage drop experienced as the switch is turned on into a large capacitive load.
Output Capacitor
FDZ2040L switch works without an output capacitor. However, if parasitic board inductance forces Vout below GND when
switching off, a 1nF capacitor, COUT, should be placed between Vout and GND.
Notes: The intrinsic diode for P-Channel load switch would conduct if VOUT is greater than VIN, by a diode drop
