Single Zener Diodes Procurement Notes

Verify compliance with environmental directives such as RoHS and REACH before procurement. Confirm that the ordering suffix matches the required halogen-free status if applicable. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Check for any product change notifications regarding packaging or assembly updates prior to placing orders.

Single Zener Diodes Selection Notes

Select this component when a 27V reference with high power dissipation capability is required. The DO-15 package allows for robust thermal management compared to smaller surface-mount alternatives. Consider the 5 Ohm dynamic impedance for applications requiring stable regulation under varying load conditions. Verify that the operating junction temperature remains within specified limits during design.

Single Zener Diodes Part Context

This part belongs to the 1N5338B through 1N5388B series, covering Zener voltages from 5.1V to 200V. All devices in this family share the same DO-15 mechanical outline and 5W power rating. The series offers standardized mounting dimensions and thermal characteristics, facilitating consistent design practices across different voltage requirements.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 27V nominal voltage, 5W power rating, and DO-15 package. Verify that substitute components meet the same ±5% tolerance and dynamic impedance specifications. Ensure thermal resistance and lead solderability standards are equivalent to maintain circuit reliability.

Single Zener Diodes FAQ

What is the maximum operating junction temperature?

The maximum operating junction temperature is 200°C for pulsed conditions with low duty cycle, while the limit for DC conditions is 150°C.

How is the maximum regulator current determined?

The maximum regulator current is based on the maximum voltage of a 5% type unit and applies only to the B-suffix device. It should not exceed 5 watts divided by the actual Zener voltage.
