Single Zener Diodes Procurement Notes

Verify the specific suffix 'BG' confirms the hermetic glass seal and military-grade screening level as defined by onsemi documentation. Ensure the procurement specification matches the required JEDEC registration and thermal performance characteristics for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when hermetic sealing and extended temperature operation are critical requirements. The DO-204AL package suits through-hole mounting configurations. Confirm that the 18V regulation point aligns with circuit design specifications and that the 1.5W power dissipation rating meets system load demands.

Single Zener Diodes Part Context

This device belongs to the 1N5913B through 1N5956B series of 1.5-watt Zener diodes. The 'G' suffix denotes the glass encapsulation variant, while 'B' indicates the specific voltage tolerance and screening level. This series provides a wide selection of regulated voltages from 3.3V to 200V for robust power management solutions.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N5931 variants with identical electrical ratings and DO-204AL packages. Verify pinout compatibility and ensure replacement components meet the same hermetic sealing and temperature rating standards.
