onsemi NJVNJD2873T4G-VF01

Overview

NJVNJD2873T4G-VF01 from onsemi is an NPN silicon power transistor in DPAK (TO-252) package, designed for high-gain audio amplifier stages. It delivers 2 A continuous collector current, 50 V collector-emitter breakdown voltage, and low 0.3 V saturation voltage at IC = 1 A / IB = 0.05 A - enabling efficient Class AB output stages in compact surface-mount audio systems.

For engineers reviewing the NJVNJD2873T4G-VF01 datasheet, pinout, applications, or equivalent options, key selection criteria include DC current gain (hFE ≥ 120 at IC = 0.5 A), thermal resistance (RθJC = 10 °C/W), AEC-Q101 qualification, Pb-free RoHS compliance, and DPAK-3 mechanical compatibility with standard PCB footprints.

Technical Context

This discrete NPN transistor operates as a linear amplifying device in analog signal paths, not as a switching element. Its high hFE bandwidth product (fT = 65 MHz) supports stable gain up to mid-audio frequencies, while its low VCE(sat) and VBE(sat) minimize conduction losses in biased output stages.

The device is rated for junction temperatures from −65 °C to +175 °C and features UL 94 V−0 compliant epoxy encapsulation. Thermal derating is defined for both case-mounted (0.1 W/°C above 25 °C) and ambient-mounted (0.011 W/°C above 25 °C) configurations, reflecting its dual-use capability in thermally constrained or heatsinked designs.

FAQ

What is the maximum continuous collector current rating for NJVNJD2873T4G-VF01?

The NJVNJD2873T4G-VF01 has a maximum continuous collector current (IC) rating of 2 A at TC = 25 °C. Derating applies above 25 °C at 0.1 W/°C for case-mounted operation. This rating assumes proper PCB copper area per onsemi's recommended minimum pad sizes to maintain thermal performance. The NJVNJD2873T4G-VF01 must not exceed this limit under sustained DC or low-duty-cycle conditions to avoid junction overheating.
