The J175, J176, MMBFJ175, MMBFJ176, and MMBFJ177 are a series of P-Channel switches designed and manufactured by onsemi™, suitable for low-level analog switching, sample-and-hold circuits, and chopper-stabilized amplifiers. These components are sourced from process 88, indicating a specific manufacturing technique employed by onsemi™ to ensure consistent performance and reliability. The devices are offered in both TO-92 and SOT-23 packages, catering to a variety of mounting preferences and application requirements. They are characterized by their ability to handle a drain-gate voltage of -30V, a gate-source voltage of 30V, and a forward gate current of 50 mA. Operating and storage junction temperature ranges are specified from -55 to +150°C, ensuring robustness across a wide range of environmental conditions. With features like low on-resistance and high transconductance, these components are optimized for efficient signal modulation and minimal power loss, making them highly suitable for precision applications in analog signal processing.

A power switch using a push button. It turns on with a single press and only turns off when you hold the button down.

A momentary or non-latching switch which causes a temporary change in the state of an electrical circuit only while the switch is physically actuated.
