Single Zener Diodes Procurement Notes

Verify the specific suffix _T50R against official datasheets to confirm packaging details such as reel specifications or cut tape requirements. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the component meets all required thermal and electrical ratings for the target application environment before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 2.5 V reference is required in a through-hole configuration. Consider the 500 mW power rating and the wide operating temperature range up to 200°C for demanding environments. Compare the 30 Ohm Zener impedance against other series members if lower impedance is necessary for specific noise-sensitive applications.

Single Zener Diodes Part Context

This part belongs to the 1N52-series family of small-signal Zener diodes manufactured by onsemi. The series is characterized by silicon planar construction and standard voltage tolerances. These diodes are widely used in consumer electronics and industrial equipment where reliable voltage clamping and referencing are essential.

Single Zener Diodes Replacement Considerations

Compatible substitutes include Vishay 1N5222B and STMicroelectronics 1N5222BAR2. Verify that alternative manufacturers maintain identical pinout configurations, voltage tolerances, and package dimensions to ensure mechanical compatibility.
