NHDTC123JTVL

Overview

The NHDTC123JTVL is an NPN Resistor-Equipped Transistor (RET) from Nexperia, housed in a SOT23 (TO-236AB) surface-mounted package. It integrates bias resistors to simplify circuit design and reduce component count. Key electrical parameters include a collector-emitter voltage (VCEO) of 80 V and an output current capability of 100 mA. The built-in input resistor R1 is nominally 2.2 kΩ, while the base resistor R2 is 47 kΩ. The device features a DC current gain (hFE) of at least 100 at IC = 10 mA and a transition frequency (fT) typical of 170 MHz. It is AEC-Q101 qualified for automotive applications.

Feature Summary

• Integrates internal bias resistors to minimize external components and assembly costs
• High breakdown voltage rating suitable for robust digital switching applications
• Qualified under AEC-Q101 standards for automotive reliability requirements

Applications

• Digital logic interface circuits
• Controlling integrated circuit inputs
• General-purpose load switching

Procurement Notes

Verify the specific ordering suffix 'VL' against the official Nexperia datasheet or distributor documentation to confirm reel packaging specifications. Ensure the part number matches the exact resistance values (R1=2.2kΩ, R2=47kΩ) required for the target application design. Cross-reference the marking code QJ% for production batch identification during incoming inspection.

Selection Notes

Select this component when a compact NPN switch with integrated base drive is needed. The 2.2 kΩ input resistor sets the base current limit; verify compatibility with the driving source voltage to ensure proper saturation. Compare thermal resistance values against the PCB copper layer configuration to validate power dissipation limits under expected operating conditions.

Part Context

This part belongs to the NHDTC123JT/143ZT/114YT series, which shares identical pinout and general characteristics but varies in internal resistor values. The NHDTC123JT variant specifically uses a 2.2 kΩ input resistor, distinguishing it from the 4.7 kΩ and 10 kΩ options in the same family. All variants utilize the SOT23 package and maintain the same 80 V / 100 mA ratings.

Replacement Considerations

The NHDTA123JT is the documented PNP complement within the same Nexperia series. Direct substitution requires verifying polarity inversion and ensuring the replacement component meets the specific thermal and voltage constraints of the existing circuit layout.
