1N5236BUR-1

Single Zener Diodes Overview

The Microchip Technology 1N5236BUR-1 is a surface mount Zener voltage regulator with a nominal breakdown voltage of 7.5 V at a test current of 20 mA. It operates within a junction temperature range of -65 °C to +175 °C and dissipates up to 0.5 W. The device features a maximum dynamic impedance of 6.0 Ohms at the test current and 500 Ohms near the knee current. Reverse leakage current is limited to 3.0 µA, and the voltage temperature coefficient is +0.058 %/°C.

Single Zener Diodes Procurement Notes

Verify the specific suffix letters on the part number to confirm the exact voltage tolerance required for the application. Confirm whether RoHS compliance is necessary, as commercial grade versions are available in compliant configurations while others may not be. Ensure the ordering nomenclature matches the desired reliability level and screening standards before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required for high-reliability applications. The metallurgical bond provides robustness against mechanical stress. Consider the positive temperature coefficient for stability requirements. Verify that the 0.5 W power dissipation rating aligns with the thermal management capabilities of the target printed circuit board layout.

Single Zener Diodes Part Context

This device belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, which serves as the surface mount equivalent to the JEDEC registered axial-leaded 1N5221 to 1N5281 series. The series covers a wide voltage selection from 2.4 to 200 volts. These regulators utilize a DO-213AA MELF style package designed for automated surface mount assembly processes.

Single Zener Diodes Replacement Considerations

The 1N5236B-1 is an axial-leaded alternative within the same product family.
