    Video: MOSFET: Depletion Mode
    A 4PST (Four-Pole Single-Throw) depletion-mode switch, such as the onsemi FSA550, is a normally-closed, high-performance isolation switch that conducts signals when no power (
    VCCcap V sub cap C cap C end-sub
    𝑉𝐶𝐶
    ) is available and isolates them when
    VCCcap V sub cap C cap C end-sub
    𝑉𝐶𝐶
     is applied. It utilizes depletion-mode technology to allow signals to pass without power, making it ideal for low-power, "normally-on" routing applications, such as audio signal paths in mobile devices. 
    Key Characteristics and Functions: 
    • Normally Closed: Conducts when
      VCCcap V sub cap C cap C end-sub
      𝑉𝐶𝐶
       is
      0V0 V
      0V
      , and disconnects when a control voltage is applied.
    • Applications: Primarily used for routing audio, data, or video signals where a fail-safe or default "on" path is required, such as in headphones or mobile devices.
    • Operational Mechanism: Unlike enhancement-mode devices that are "off" by default, depletion-mode devices have a pre-formed channel that requires a negative gate-source voltage (
      VGScap V sub cap G cap S end-sub
      𝑉𝐺𝑆
      ) to turn off.
    • Performance: Offers low power consumption and high isolation to prevent signal interference. 
    Examples of this type of switch include the FSA550 4PST Depletion-Mode Isolation Switch and the SUMSEMI SUM5504.
