2N5462G

Overview

The onsemi 2N5462G is a small signal field-effect transistor featuring a single P-channel silicon junction structure. It operates in depletion mode and utilizes a TO-92 through-hole package with three terminals. The device exhibits a maximum feedback capacitance (Crss) of 2 pF, ensuring low noise performance suitable for sensitive applications. It supports a maximum operating temperature of 135 °C and employs a plastic/epoxy cylindrical encapsulation.

Feature Summary

• Designed primarily for low-level audio and general-purpose applications involving high impedance signal sources
• Features low noise characteristics optimized for sensitive circuit environments
• Utilizes a standard TO-92 through-hole package configuration

Applications

• Low level audio amplification circuits
• General purpose amplifier stages
• High impedance signal source interfacing

Procurement Notes

Verify the specific manufacturer origin and lot traceability upon receipt, as multiple vendors produce this component. Confirm that the physical marking matches the ordered part number to ensure correct polarity and functionality. Check for any agency-specific qualification requirements if the application demands certified reliability standards beyond standard commercial specifications.

Selection Notes

Select this component when a P-channel JFET with low noise and high input impedance is required for audio or signal processing tasks. Ensure the circuit design accommodates the depletion mode operation where current flows at zero gate-source voltage. Verify that the thermal management strategy supports the specified maximum operating temperature limits under continuous load conditions.

Part Context

This component belongs to the 2N5460/5461/5462 series of P-channel general-purpose amplifiers. It shares functional similarities with the MMBF5462 surface-mount variant but offers a through-hole package option. The series is sourced from Process 89 technology, providing consistent performance across different manufacturers producing these legacy part numbers.

Replacement Considerations

Direct substitutes include the 2N5462RLRP and 2N5462D74Z, which share identical electrical characteristics and TO-92 packaging. Surface-mount equivalents such as the MMBF5462 are functionally compatible but require PCB layout adjustments due to package differences.
