The onsemi 2N5401_D81Z is a PNP epitaxial silicon transistor housed in a TO-92 package. It supports a collector-emitter voltage of -150 V and a collector current of -600 mA, with a maximum power dissipation of 625 mW at 25°C ambient temperature. The device features a collector-base breakdown voltage of -160 V and an emitter-base breakdown voltage of -5 V. Electrical characteristics include a DC current gain ranging from 30 to 240 depending on the operating point, a transition frequency up to 400 MHz, and a noise figure of 8 dB.
Verify the specific ordering suffix against official manufacturer documentation to confirm pinout configuration and packaging details. Ensure that the component meets all absolute maximum ratings during operation to prevent damage. Cross-reference datasheet revisions to confirm electrical parameters remain consistent with design requirements.
Select this component when a PNP transistor with high voltage capability and moderate current handling is required. Consider the thermal resistance and power dissipation limits relative to the expected operating environment. Evaluate the noise figure and bandwidth specifications against the specific signal processing needs of the target application.
This part belongs to the 2N5401 family of PNP transistors originally documented by Fairchild Semiconductor, now managed by onsemi. The device is designed as a general-purpose amplifier transistor offering reliable performance in standard electronic circuits. It utilizes a three-terminal TO-92 through-hole package for easy integration into printed circuit boards.
Consult official substitution guides for verified equivalents. Generic replacements must match the PNP polarity, voltage ratings, and package type.
