Overview
The PDTA114TK is a PNP Resistor-Equipped Transistor (RET) from the PDTA114T series, housed in an SOT346 (SC-59A/TO-236) surface-mount package. It integrates a PNP transistor with a built-in base bias resistor R1 of 10 kΩ and an open emitter resistor R2. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V, an output current capability of -100 mA, and a total power dissipation of 250 mW at 25 °C ambient temperature. The device features a DC current gain (hFE) of 200 minimum at -1 mA collector current and a saturation voltage of -150 mV maximum at -10 mA.
Feature Summary
- Integrates a PNP transistor with a fixed 10 kΩ input bias resistor to reduce component count.
- Designed for digital applications as a cost-saving alternative to discrete transistor-resistor networks.
- Simplifies circuit design by eliminating external biasing components.
Applications
- Control of IC inputs
- Low current peripheral driver
- Digital switching applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current product status documentation. Confirm that the SOT346 package variant matches the required footprint for the target PCB layout. Ensure compatibility with reflow soldering profiles specified in the thermal characteristics section. Cross-reference the marking code '23' for quality assurance during incoming inspection.
Selection Notes
Select this component when a compact PNP switching solution with integrated biasing is required. The SOT346 package offers a small form factor suitable for space-constrained designs. Verify that the -50 V voltage rating and -100 mA current limit meet the load requirements. Consider the 250 mW power dissipation capability relative to the expected operating temperature and PCB copper area.
Part Context
This part belongs to the PDTA114T family of PNP Resistor-Equipped Transistors. The family includes variants in different packages such as SOT23, SOT323, and SOT883. The PDTA114TK specifically utilizes the SOT346 package, which corresponds to the SC-59A and TO-236 mechanical standards. The NPN complement for this device is the PDTC114TK.
Replacement Considerations
Direct functional equivalents within the same series include other PDTA114T package variants if the footprint allows. The NPN counterpart is the PDTC114TK. Discrete alternatives would require pairing a PNP transistor with an external 10 kΩ resistor.
