Overview
The DDTC114EKA-7-F is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated, housed in a SC-59 package. It features built-in biasing resistors with nominal values of R1 = R2 = 10 kΩ. The device supports a maximum supply voltage (VCC) of 50 V and a continuous collector current (IC) of 100 mA. Power dissipation is rated at 200 mW, with an operating temperature range spanning -55°C to +150°C. The typical gain-bandwidth product (fT) is 250 MHz.
Feature Summary
- Epitaxial planar die construction with integrated base and emitter biasing resistors.
- Lead-free plating with matte tin finish over copper leadframe.
- RoHS compliant and manufactured using green molding compound.
Applications
- General-purpose switching applications
- Driver circuits for logic interfaces
- Low-power digital signal processing
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details and compliance status. Ensure that the component meets all relevant environmental standards required for the intended application before finalizing procurement decisions.
Selection Notes
Select this component when a compact NPN solution with fixed internal biasing is required. Verify that the 100 mA collector current and 50 V breakdown voltage align with circuit requirements. Confirm thermal management capabilities given the 200 mW power dissipation limit in the SC-59 package.
Part Context
This part belongs to the DDTC114 series of pre-biased transistors. It shares the same electrical characteristics as other variants in the series but differs in physical packaging. The KA suffix specifically denotes the SC-59 case style, distinguishing it from SOT-23 or SOT-323 alternatives.
Replacement Considerations
Direct replacements include other DDTC114 variants with different packages such as DDTC114ECAQ-7 or DDTC114YCA-7-F, provided the footprint allows. Verify pinout compatibility and ensure the substitute maintains the 10 kΩ resistor ratio and 50 V rating.
