Overview
The onsemi J111-D74Z is an N-channel silicon small-signal Junction Field-Effect Transistor (JFET) housed in a TO-92 package. It operates in depletion mode with a single configuration and three terminals. Key electrical parameters include a maximum drain-source on-resistance of 30 Ω and a maximum feedback capacitance (Crss) of 5 pF. The device is constructed with a plastic/epoxy body, features a cylindrical round shape, and utilizes through-hole bottom terminals. It is RoHS compliant and designed for general switching applications.
Feature Summary
- N-channel silicon construction for small-signal operations
- Depletion mode functionality within a standard TO-92 through-hole package
Applications
- General electronic circuit switching
- Small-signal amplification stages
Procurement Notes
Verify the specific manufacturer designation when sourcing, as the J111 part number is utilized by multiple semiconductor producers including Texas Instruments and Rochester Electronics. Confirm that the D74Z suffix corresponds to the required packaging and marking specifications for your assembly process. Ensure the component meets current environmental compliance standards such as RoHS before finalizing procurement orders.
Selection Notes
Select this component for low-power N-channel switching requirements where a TO-92 form factor is necessary. The 30 Ω on-resistance limit defines its suitability for specific load conditions. Engineers should compare the 5 pF feedback capacitance against high-frequency application needs to ensure signal integrity is maintained during operation.
Part Context
The J111 belongs to a family of N-channel JFETs often grouped with variants like J112 and J113. These devices are characterized by their simple structure and reliability in discrete semiconductor circuits. The TO-92 package remains a standard choice for prototyping and low-volume production due to its ease of handling and mounting.
Replacement Considerations
Direct substitutes may include the J111D26Z from Texas Instruments or generic J111 equivalents from other manufacturers. Verify pinout compatibility and parameter tolerances, specifically the 30 Ω resistance and 5 pF capacitance limits, before implementing any cross-manufacturer replacement.
