DDTC114YE-7-F

Overview

The DDTC114YE-7-F is an NPN pre-biased transistor manufactured by Diodes Incorporated, housed in a SOT523 surface-mount package. It integrates internal biasing resistors with nominal values of R1 = 10 kΩ and R2 = 47 kΩ. The device supports a maximum supply voltage (VCC) of 50 V and a continuous collector current (IC) of 100 mA. Key electrical characteristics include a DC current gain (hFE) of 68 at IO = 10 mA, a transition frequency (fT) of 250 MHz, and a power dissipation rating of 150 mW. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Integrates two unequal biasing resistors (R1≠R2) within a single compact SOT523 package to reduce external component count.
• Utilizes epitaxial planar die construction for reliable switching performance.
• Manufactured as a lead-free, halogen-free, and antimony-free 'Green' device compliant with RoHS directives.

Applications

• General-purpose digital switching circuits
• Driver applications for low-power loads
• Logic level translation interfaces

Procurement Notes

Verify the specific ordering suffix '-7-F' against the manufacturer's official documentation to confirm packaging details. The datasheet specifies that this part number corresponds to a 3,000-unit reel size on a 7-inch carrier with an 8mm tape width. Confirm compliance requirements such as RoHS 3 and REACH status directly with the supplier or manufacturer before procurement.

Selection Notes

Select this component when a single NPN pre-biased transistor with a 10 kΩ base resistor and 47 kΩ emitter resistor is required. Ensure the application voltage does not exceed the 50 V supply limit and the output current remains within the 100 mA continuous rating. Verify that the SOT523 package dimensions fit the target PCB layout constraints.

Part Context

This component belongs to the DDTC (R1≠R2 Series) E family from Diodes Incorporated. It is specifically designed as an NPN pre-biased transistor variant. Complementary PNP types are available within the same series under the DDTA designation. The device is intended for use in space-constrained designs requiring integrated biasing networks.

Replacement Considerations

Direct substitutes within the same series include DDTC114WE-7-F, which shares the SOT523 package but features different resistor values (R1=10kΩ, R2=22kΩ). Cross-manufacturer equivalents may exist but require verification of pinout compatibility, electrical ratings, and package dimensions.
