ADTC143ZCAQ-13

Single, Pre-Biased Bipolar Transistors Overview

The ADTC143ZCAQ-13 is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors with nominal values of R1 = 4.7 kΩ and R2 = 47 kΩ, eliminating the need for external components in inverter circuits. The device operates within a supply voltage range up to 50 V and supports a continuous collector current of 100 mA. It is housed in a SOT-23 package with a power dissipation rating of 310 mW at +25°C ambient temperature. Qualified to AEC-Q101 standards, it ensures high reliability for automotive applications.

Single, Pre-Biased Bipolar Transistors Feature Summary

• Integrated biasing resistors simplify circuit design by removing the requirement for external input resistors.
• Qualified to AEC-Q101 standards for high reliability and PPAP capable for automotive manufacturing processes.
• Constructed using epitaxial planar die technology for robust performance.
• Compliant with RoHS directives and halogen/antimony-free green device specifications.

Single, Pre-Biased Bipolar Transistors Applications

• Automotive interface circuits
• Driver circuits for low-power loads
• Inverter logic applications

Single, Pre-Biased Bipolar Transistors Procurement Notes

Verify the specific ordering suffix '-13' corresponds to the 10,000-unit reel quantity rather than the '-7' variant which contains 3,000 units per reel. Confirm that the '2A9' product marking code matches the required identification for your assembly process. Ensure compliance with the specified moisture sensitivity level and storage conditions upon receipt.

Single, Pre-Biased Bipolar Transistors Selection Notes

Select this component when an NPN configuration with a 4.7 kΩ base resistor and 47 kΩ emitter-base resistor is required. The SOT-23 package is suitable for space-constrained surface mount designs. Consider the complementary ADTA143ZCAQ if a PNP equivalent is needed for push-pull or differential configurations.

Single, Pre-Biased Bipolar Transistors Part Context

This part belongs to the ADTC series of pre-biased transistors from Diodes Incorporated. It serves as the NPN counterpart to the ADTA series PNP devices. The 'ZCA' designation indicates the specific internal resistor ratio and polarity, while the 'Q' suffix denotes AEC-Q101 qualification for automotive use.

Single, Pre-Biased Bipolar Transistors Replacement Considerations

The ADTC143ZCAQ-7 is a direct functional substitute with identical electrical characteristics but packaged in 3,000-unit reels instead of 10,000-unit reels. Other generic NPN digital transistors may require verification of resistor ratios and hFE gain ranges to ensure compatibility.
