Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'W' against official documentation to confirm packaging details such as tape and reel specifications or quantity per unit. Ensure the ordering code matches the required hFE binning classification (V or W) for your design constraints. Confirm RoHS compliance status through the manufacturer's latest datasheet revision before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a small-signal NPN transistor requires high current gain and low saturation voltage within a compact SPT package. It serves as a suitable alternative to the 2SD2114K, which shares identical electrical parameters but utilizes a different physical package configuration. Consider thermal dissipation limits and operating temperature ranges during circuit design.

Single Bipolar Transistors Part Context

This part belongs to the 2SD2114K/2SD2144S family of medium-power transistors designed for general electronic equipment. It is manufactured by ROHM Semiconductor using epitaxial planar technology. The device is intended for ordinary electronic devices such as office automation and communications equipment, rather than safety-critical automotive or aerospace applications.

Single Bipolar Transistors Replacement Considerations

The 2SD2114K is a direct functional equivalent with identical electrical specifications but uses the SC-59 package instead of SC-72. Designers must verify pinout compatibility and mechanical footprint differences before substituting packages in existing layouts.
