Procurement Notes

Verify the specific suffix against manufacturer documentation, as the provided reference data primarily lists the APM variant for this model number. Confirm package type and thermal ratings match design requirements. Ensure compliance with REACH regulations and check for any regional export classification restrictions before finalizing procurement.

Selection Notes

Select this component when a ruggedized through-hole UJT is required for high-reliability environments. Compare the 300 mW power dissipation limit against circuit load requirements. Consider the TO-92-3 footprint constraints and verify that the 40V breakdown voltage exceeds the maximum operating potential of the target application.
