DDTB142JU-7-F

Overview

The DDTB142JU-7-F is a PNP pre-biased surface mount transistor from Diodes Incorporated, housed in an SOT-323 package. It integrates built-in biasing resistors with nominal values of R1 = 0.47 kΩ and R2 = 10 kΩ. The device supports a maximum collector current of -500 mA and a power dissipation of 200 mW. Key electrical ratings include a collector-emitter breakdown voltage (BVCEO) of -40 V and a collector-base breakdown voltage (BVCBO) of -50 V. The DC current gain (hFE) ranges from 100 to 600 at IC = -5 mA, with a minimum gain of 56 under specific test conditions.

Feature Summary

Integrates built-in biasing resistors to simplify circuit design
Utilizes epitaxial planar die construction for reliability
Offers complementary NPN types within the same series

Applications

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

Procurement Notes

Verify component authenticity through authorized channels. Confirm RoHS compliance status via official documentation. Check for End-of-Life notices or production change notifications prior to procurement. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the datasheet.

Selection Notes

Select this component for designs requiring a compact PNP solution with integrated base resistance. Verify that the required current gain meets the application's saturation needs. Ensure the operating temperature range aligns with system constraints. Consider the SOT-323 footprint compatibility during PCB layout.

Part Context

This part belongs to the DDTB series of pre-biased transistors. It shares the SOT-323 form factor with other variants like the DDTB122LU and DDTB142TU. The series provides options for different resistor ratios and configurations, including R1-only and dual-resistor types.

Replacement Considerations

Direct substitutes include DDTB142TU-7-F, which shares the same package and polarity but lacks the R2 resistor. Verify pinout compatibility and electrical parameters before substitution.
