DDTA143TUA-7-F Description

Short technical summary and product information.

The DDTA143TUA-7-F is a PNP pre-biased transistor from Diodes Incorporated, part of the DDTA (R1-Only) series. It features a built-in biasing resistor (R1) of 4.7 kΩ, simplifying circuit design by reducing external component count.

Electrical characteristics include a minimum collector-emitter breakdown voltage of 50 V, collector-base breakdown voltage of 50 V, and emitter-base breakdown voltage of 5 V. Maximum collector current is 100 mA with a power dissipation of 200 mW. DC current gain (hFE) is minimum 100 at Ic=1mA, Vce=5V. Transition frequency is 250 MHz.

The transistor is housed in a SOT-323 surface mount package, with a weight of 0.006 grams. It is supplied in tape and reel packaging with 3000 pieces per reel, suitable for automated assembly. The device is RoHS3 compliant, halogen and antimony free, and has an MSL of Level 1.

This pre-biased transistor is suitable for switching and amplification applications where space and component count are critical. The built-in resistor ensures consistent biasing, making it ideal for high-volume production.
