DDTC143EKA-7-F

Overview

The DDTC143EKA-7-F is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SC-59 package. It features built-in biasing resistors with a nominal value of 4.7 kΩ and a resistance ratio of 1. The device supports a supply voltage (VCC) of 50 V and a continuous output current (IO) of 100 mA. Power dissipation is rated at 200 mW, with a thermal resistance (RθJA) of 625 °C/W. Operating and storage temperatures range from -55°C to +150°C. The input voltage limit for this specific model is -10 V to +30 V.

Feature Summary

Built-in biasing resistors with R1 = R2 configuration
Lead-free and RoHS compliant manufacturing
Green molding compound material

Applications

Inverter circuits
Driver circuits
Switching applications

Procurement Notes

Verify the component against the official datasheet DS30337 Rev. 8. Confirm the SC-59 package type and the specific electrical characteristics for the DDTC143 series. Ensure compliance with lead-free requirements if applicable to the assembly process.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required. The SC-59 package offers a small footprint suitable for space-constrained designs. Verify that the 50 V supply voltage and 100 mA current ratings meet the circuit requirements.

Part Context

This part belongs to the DDTC (R1 = R2 Series) family of pre-biased transistors. It serves as the NPN counterpart to the DDTA series. The 'KA' suffix indicates the SC-59 package style, while the '143' designation specifies the 4.7 kΩ resistor value.

Replacement Considerations

Compatible substitutes within the same series include DDTC123EKA-7-F and DDTC114EKA-7-F, provided their respective resistor values and current ratings align with the design specifications.
