2N6028RLRA

Overview

The 2N6028RLRA is a silicon programmable unijunction transistor (PUT) manufactured by onsemi. It utilizes a TO-92 plastic package for through-hole mounting. The device supports a maximum voltage of 40V and a power dissipation of 300 mW. Key electrical parameters include a typical peak output voltage of 11 V, a maximum gate-to-anode leakage current of 10 nA, and a low offset voltage of 0.35 V typical with RG at 10 kΩ. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Engineers can program unijunction characteristics such as RBB, η, IV, and IP by selecting two external resistor values.
• Features a low on-state voltage of 1.5 V maximum at IF = 50 mA.
• Includes an available anode gate for special thyristor applications.
• Designed for high-volume requirements with automatic insertion equipment compatibility.

Applications

• Thyristor triggering circuits
• Oscillator designs
• Pulse generation circuits
• Timing circuits

Procurement Notes

Verify the specific suffix RLRA against the official datasheet to confirm lead-free status and pinout configuration. Ensure the procurement source provides the original manufacturer documentation from onsemi rather than third-party interpretations. Confirm that the component matches the TO-92 package style specified in the technical data before integration into production lines.

Selection Notes

Select this component when precise control over unijunction characteristics is required via external resistors. It is suitable for applications needing a low offset voltage and high peak output. Consider the TO-92 package constraints for thermal management and board space. Verify that the 40V rating meets the circuit's voltage requirements.

Part Context

This part belongs to the programmable unijunction transistor family offered by onsemi. It serves as a solid-state alternative to traditional UJTs, offering greater stability and ease of use in timing and triggering applications. The device is designed to replace older technologies while maintaining compatibility with standard circuit topologies.

Replacement Considerations

Check for direct substitutes like the 2N6028RLRAG which shares identical functional specifications. Verify pinout compatibility and package dimensions when substituting with other manufacturers' programmable UJTs such as those from NXP or Siemens.
