DTC114WSATP

Overview

The DTC114WSATP is an NPN epitaxial planar silicon digital transistor with built-in resistors, manufactured by Rohm Semiconductor. It operates with a supply voltage of up to 50V and a continuous collector current of 100mA. The device features a DC current gain (GI) of at least 24 and a transition frequency (fT) of 250MHz. Power dissipation is rated at 300mW. It utilizes the SPT package with a taping code of TP and a basic ordering unit of 5000 pieces.

Feature Summary

• Built-in bias resistors enable inverter circuit configuration without external input resistors.
• Thin-film resistors provide complete isolation for negative input biasing.
• Parasitic effects are minimized through resistor design.

Applications

• Inverter circuits
• Interface applications
• Driver circuits

Procurement Notes

Verify the specific suffix 'TP' corresponds to the required tape-and-reel quantity of 5000 units. Confirm the SPT package dimensions match the target PCB land pattern. Ensure the component meets RoHS compliance requirements for the intended assembly process.

Selection Notes

Select this model when a compact NPN digital transistor with 50V rating and 100mA current capacity is needed. The SPT package offers a small footprint suitable for high-density mounting. Verify that the 300mW power dissipation rating accommodates the thermal conditions of the final application.

Part Context

This component belongs to the DTC114 series of digital transistors from Rohm Semiconductor. It shares electrical characteristics with the DTC114WE, DTC114WUA, and DTC114WKA models but differs in packaging. The SPT package distinguishes it from the EMT3, UMT3, and SMT3 variants within the same family.

Replacement Considerations

DTC114WE, DTC114WUA, DTC114WKA share identical electrical specifications but utilize different packages (EMT3, UMT3, SMT3). Substitution requires verifying mechanical fit and lead compatibility.
