Overview
The ZDT795AQTA is a dual PNP medium power transistor manufactured by Diodes Incorporated. It operates with a collector-emitter voltage of -140V and supports a continuous collector current of -0.5A. The device features a DC current gain ranging from 250 to 800, depending on the operating current. It has a maximum power dissipation of 2.75W when both dies are active. The component utilizes an SM-8 package (8-lead SOT-223) and is qualified under AEC-Q101 standards for automotive applications.
Feature Summary
- Dual PNP configuration housed in an SM-8 surface-mount package
- High breakdown voltage exceeding -140V for robust operation
- AEC-Q101 qualification suitable for stringent automotive environments
- Lead-free and halogen-free construction compliant with environmental directives
Applications
- Automotive electronic systems requiring specific change control
- Medium power switching circuits
- General-purpose amplifier stages
Procurement Notes
Verify that the ordering suffix TA corresponds to the reel packaging format specified in the manufacturer's documentation. Confirm compliance with RoHS 3 and REACH regulations before integration into final assemblies. Ensure the procurement channel is authorized to maintain warranty validity and traceability requirements.
Selection Notes
Select this component when a dual PNP configuration with high voltage tolerance is required. The SM-8 package provides efficient thermal management for medium power applications. Verify that the circuit design accommodates the specified saturation voltages and current gains across the intended operating temperature range.
Part Context
This part belongs to the ZDT795 series of dual transistors designed for automotive reliability. It shares the same electrical characteristics as the non-AQ variant but includes additional quality certifications. The marking code T795A identifies the specific product type within the SM-8 package family.
Replacement Considerations
The ZDT795ATA is a comparable single PNP transistor with similar voltage ratings but lacks the dual configuration. Direct replacement requires evaluating if the second die is necessary for the circuit topology.
