DDTC144GUA-7

Overview

The DDTC144GUA-7 is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated, housed in a SOT-323 package. It features a built-in biasing resistor (R2) with a nominal value of 47 kOhms. 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 minimum DC current transfer ratio (hFE) of 68 at IC = 5mA and VCE = 5V, with a gain-bandwidth product (fT) of 250 MHz. Operating temperature ranges from -55°C to +150°C.

Feature Summary

Epitaxial planar die construction for reliable performance
Integrated single biasing resistor (R2 only) simplifies circuit design
Lead-free plating with matte tin finish over alloy 42 leadframe
RoHS compliant and available in green molding compound

Applications

General-purpose switching applications
Driver circuits for low-power loads
Logic interface buffering

Procurement Notes

Verify the specific ordering suffix against official documentation, as variations such as -7-F indicate tape and reel packaging quantities. Confirm RoHS compliance status and manufacturing date codes for material specifications. Ensure compatibility with standard SMD/SMT assembly processes and check for any specific handling requirements related to moisture sensitivity level 1.

Selection Notes

Select this component when a compact NPN digital transistor with a 47 kOhm base resistor is required. Compare hFE and saturation voltage characteristics against circuit requirements. Consider the SOT-323 footprint constraints and thermal resistance values for proper heat dissipation in the target application environment.

Part Context

This part belongs to the DDTC (R2-only series) UA family from Diodes Incorporated. It serves as the NPN counterpart to the DDTA PNP pre-biased transistors. The '144' designation specifically indicates the 47 kOhm internal resistor value within this standardized series.

Replacement Considerations

Direct replacements may include other NPN pre-biased transistors with similar R2 values and SOT-323 packages. Verify pinout compatibility and electrical parameters such as VCEO, IC, and hFE before substitution.
