2SK772E

Jfets Overview

The 2SK772E is an N-channel Junction Field-Effect Transistor (JFET) manufactured by onsemi. It utilizes the FBET process and is housed in a SPAK package, which is a through-hole component rather than surface-mount. The device features a single base configuration with Source, Gate, and Drain terminals. Key electrical characteristics include a maximum drain-to-source voltage of 60V and a gate-to-source voltage rating of ±30V. The absolute maximum power dissipation is rated at 0.3W at 25°C ambient temperature. The junction temperature limit is 150°C, and it supports storage temperatures ranging from -55°C to 150°C.

Jfets Feature Summary

• Utilizes FBET process technology for stable performance
• Designed for low-noise analog signal applications
• Through-hole SPAK packaging for reliable mounting

Jfets Applications

• Audio frequency (AF) amplifiers
• Analog switches
• Variable resistors
• Constant-current circuits

Jfets Procurement Notes

Verify the specific suffix 'E' against the official onsemi datasheet EN2392A to confirm material or compliance variations. Ensure the SPAK package type matches the target PCB footprint requirements. Confirm RoHS status and lead-free specifications directly from the manufacturer's documentation prior to ordering.

Jfets Selection Notes

Select this component for low-noise pre-amplification stages where high input impedance is required. Compare the 1.2mA I(DSS) specification against circuit biasing needs. Consider thermal management as the power dissipation is limited to 0.3W. Verify that the N-channel polarity aligns with the system design.

Jfets Part Context

The 2SK772E belongs to the 2SK772 series of N-channel JFETs. It is functionally related to variants such as the 2SK772F, which differs primarily in the drain current saturation level (I(DSS)). Both devices share the same SPAK package and core FBET process architecture intended for audio and analog switching applications.

Jfets Replacement Considerations

Direct substitutes within the same family include the 2SK772F, noting the difference in I(DSS). Cross-compatibility with other N-channel JFETs requires verification of pinout alignment and voltage ratings. No official cross-reference list is provided in the source data.
