2N6028RLRAG

Overview

The ON Semiconductor 2N6028RLRAG is a programmable unijunction transistor (PUT) housed in a TO-92 plastic package. It allows engineers to program characteristics such as RBB, η, IV, and IP by selecting two resistor values. Key electrical parameters include a maximum on-state voltage of 1.5 V at IF = 50 mA, a maximum gate-to-anode leakage current of 10 nA, a typical peak output voltage of 11 V, and a typical offset voltage of 0.35 V with RG = 10 kΩ.

Feature Summary

• Programmable unijunction characteristics including RBB, η, IV, and IP via external resistor selection
• Low on-state voltage of 1.5 V maximum at IF = 50 mA
• Low gate-to-anode leakage current of 10 nA maximum
• High peak output voltage of 11 V typical

Applications

• Thyristor-trigger circuits
• Oscillator circuits
• Pulse generation circuits
• Timing circuits

Procurement Notes

Verify the specific suffix RLRA or RLRAG against the manufacturer's current datasheet to confirm pinout compatibility and lead-free status. Ensure the TO-92 package dimensions match your PCB footprint requirements. Confirm that the programming resistors selected for your design align with the specified RBB and η ranges to achieve the desired trigger characteristics.

Selection Notes

Select this component when precise control over unijunction characteristics is required through external resistor networks rather than fixed internal parameters. The TO-92 package makes it suitable for high-volume automatic insertion equipment. Consider the low offset voltage and high peak output voltage when designing sensitive timing or pulse applications where signal integrity is critical.

Part Context

The 2N6028 series belongs to the family of programmable unijunction transistors designed to replace traditional UJTs with greater flexibility. By allowing the programmer to set key parameters via external resistors, these devices offer tailored performance for specific circuit needs while maintaining the reliability and cost-effectiveness associated with standard bipolar transistor packages.

Replacement Considerations

The 2N6028RLRA is a direct functional equivalent within the same product line. Other programmable unijunction transistors from different manufacturers may serve as substitutes if pinouts and electrical specifications are verified to be compatible.
