The J177_D27Z is an N-channel Junction Field-Effect Transistor (JFET) manufactured by onsemi. It is designed for small-signal switching and amplification applications. The device utilizes silicon technology and is housed in a TO-92-3 Kinked Lead through-hole package. Key electrical characteristics include a gate-source breakdown voltage of -35 V, a gate-source cutoff voltage of -5 V, and a drain-source on-resistance of 50 Ohms. At zero gate-source voltage, the drain-source current is specified at 5 mA. The component supports a maximum power dissipation of 625 mW.
Verify the specific suffix D27Z against official onsemi documentation to confirm tape-and-reel or cut-tape availability. Ensure the ordering part number matches the exact pinout and lead form factor required for the target PCB footprint. Cross-reference the manufacturer's latest datasheet revision to confirm compliance with current environmental standards and material declarations before finalizing procurement orders.
Select this component when an N-channel depletion-mode JFET is required for low-voltage control applications. The TO-92 package is suitable for prototyping and low-volume production where through-hole assembly is preferred. Evaluate the 50 Ohm on-resistance and 625 mW power dissipation limits to ensure compatibility with the circuit's thermal and impedance requirements. Confirm that the -35 V gate-source breakdown voltage provides sufficient margin for the intended operating conditions.
This component belongs to the J112 series of N-channel JFETs produced by onsemi. The series is characterized by its use in general-purpose small-signal applications. The J177_D27Z designation identifies the specific variant within this family, distinguished by its packaging and manufacturing lot codes. It serves as a discrete semiconductor solution for linear and switching operations in consumer and industrial electronics.
