DDTA114TKA-7-F

Overview

The DDTA114TKA-7-F is a PNP pre-biased small signal surface mount transistor from the R1-only series by Diodes Incorporated. It features an epitaxial planar die construction in an SC-59 package with a nominal base resistor (R1) of 10 kΩ. Key electrical ratings include a collector-emitter voltage (VCEO) of -50 V, a continuous collector current (IC) of -100 mA, and power dissipation (Pd) of 200 mW. The device exhibits a DC current transfer ratio (hFE) ranging from 100 to 600 at IC = -1mA and VCE = -5V, with a gain-bandwidth product (fT) of 250 MHz. Operating temperatures span from -55°C to +150°C.

Feature Summary

• Integrates a single built-in biasing resistor (R1) for simplified circuit design
• Utilizes epitaxial planar die construction for reliable performance
• Available in lead-free RoHS compliant packaging with green molding compound

Applications

• General-purpose switching applications requiring integrated biasing
• Driver circuits for low-power loads
• Logic interface buffering between different voltage domains

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or certified partners. Confirm the specific ordering suffix matches the required tape and reel quantity of 3000 units. Ensure compliance with environmental regulations such as RoHS and check for any relevant product change notifications prior to finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with a 10 kΩ base resistor is required in an SC-59 package. Compare against the DDTC114 series for complementary NPN options. Consider thermal resistance and derating curves if operating near maximum temperature limits or power dissipation thresholds.

Part Context

This part belongs to the DDTA114KA family of pre-biased transistors. Variants within this family differ primarily by the nominal value of the integrated base resistor (R1), ranging from 1 kΩ to 200 kΩ. The 'KA' designation specifically indicates the SC-59 case style and the 10 kΩ resistor configuration for the DDTA114 model.

Replacement Considerations

Direct substitutes include other DDTA114 variants with identical electrical characteristics but different resistor values, such as DDTA113TKA or DDTA124TKA, provided the circuit design accommodates the resistance change. Cross-reference with DDTC114 series components only if NPN polarity is acceptable.
