Overview
The onsemi J202_D74Z is an N-channel Junction Field-Effect Transistor (JFET) designed for through-hole mounting in a TO-92-3 package. It features a single transistor configuration with a maximum power dissipation of 625 mW and a gate-source breakdown voltage of 40 V. The device supports lead-free construction and operates at a maximum junction temperature of 150°C, providing reliable performance for general-purpose switching and amplification applications.
Feature Summary
- N-channel JFET configuration for signal processing
- Through-hole TO-92-3 package for easy integration
- Lead-free compliant construction
Applications
- General-purpose analog switching circuits
- Low-noise amplifier stages
- Impedance matching networks
Procurement Notes
Verify component authenticity by checking the manufacturer's marking code against official datasheet specifications. Confirm the package type matches the required TO-92-3 footprint. Ensure the part meets lead-free compliance standards if required by the assembly process. Cross-reference the specific suffix to confirm availability status, as some variants may be obsolete.
Selection Notes
Select this component when an N-channel JFET with a 40 V breakdown voltage is required. Consider the 625 mW power rating for thermal management within the TO-92-3 package. Evaluate the need for through-hole mounting versus surface-mount alternatives based on PCB design constraints. Verify that the electrical characteristics align with the target circuit's impedance and gain requirements.
Part Context
This component belongs to the onsemi discrete semiconductor portfolio, specifically within the JFET category. It complements other small-signal transistors used in audio and RF applications. The TO-92-3 form factor is common in legacy and cost-sensitive designs requiring robust through-hole reliability.
Replacement Considerations
Check for direct pin-compatible substitutes from onsemi or other manufacturers offering similar N-channel JFETs with comparable 40 V ratings and TO-92 packages. Verify electrical parameter equivalence before substitution.
