Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required Zener voltage and power rating for your circuit design. Confirm compliance with environmental standards such as RoHS if applicable to your manufacturing process. Ensure the DO-201 package dimensions align with your PCB layout constraints. Check for any specific suffixes like -Q or -AQ if automotive qualification is required, as these denote different reliability grades than the standard commercial version.

Single Zener Diodes Selection Notes

Select this component when a 36 V reference voltage is needed with moderate power handling capabilities. The DO-201 package is suitable for through-hole mounting where higher thermal mass is beneficial. Consider the dynamic resistance and test current specifications to ensure accurate voltage regulation under your specific load conditions. Verify that the operating temperature range meets the environmental requirements of the final application.

Single Zener Diodes Part Context

The 1N5365B belongs to the 1N5345B through 1N5388B series of Zener diodes from Diotec Semiconductor. This series covers a wide voltage range from 8.7 V to 200 V, all sharing the same 5 W power dissipation rating and DO-201 package form factor. The series is characterized by non-planar technology and is intended for general-purpose commercial and industrial applications requiring reliable voltage regulation.

Single Zener Diodes Replacement Considerations

Other parts within the 1N5345B-1N5388B series may be considered if voltage adjustments are acceptable. Cross-manufacturer equivalents must match the 36 V nominal voltage, 5 W power rating, and DO-201 package. Verify dynamic resistance and leakage current specifications to ensure functional compatibility in precision regulation circuits.

Single Zener Diodes FAQ

What is the standard tolerance for the Zener voltage of the 1N5365B?

The standard Zener voltage tolerance is graded to the international E 24 standard, which corresponds to ±5%.

Is the 1N5365B suitable for bi-directional overvoltage protection?

No, the datasheet specifies it for uni-directional overvoltage protection. Bi-directional protection requires TVS diodes from the 1.5KE series.

What is the maximum non-repetitive peak power dissipation?

The maximum non-repetitive peak power dissipation is 80 W for pulses with a duration less than 8.3 ms.
