1N5236A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5236A/TR is a Zener diode from the 1N5221-1N5281B series, housed in a hermetically sealed glass DO-35 (DO-204AH) axial-lead package. It provides a nominal Zener voltage of 7.5 V with a standard tolerance of ±10%, indicated by the 'A' suffix. The device operates at a test current of 20 mA and dissipates up to 0.5 watts at 25°C. Key electrical parameters include a maximum reverse leakage current of 30 µA at 5.0 V and a Zener impedance of 6.0 Ohms at 0.5 mA. It supports an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction for reliable operation
• Regulates voltage across a broad operating current and temperature range
• Inherently radiation hard per MicroNote 050
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'TR' suffix indicates tape and reel packaging compliant with EIA-296 standards. Confirm the 'A' suffix corresponds to the necessary ±10% voltage tolerance. Ensure the component meets RoHS compliance requirements if applicable, as this may require a specific 'e3' suffix variant rather than the standard leaded version.

Single Zener Diodes Selection Notes

Select this component when a 7.5 V reference is needed within the 0.5 W power dissipation class. The DO-35 package suits through-hole mounting applications requiring high reliability. Consider the ±10% tolerance for general regulation tasks. Evaluate thermal derating curves for high-temperature environments exceeding 25°C ambient conditions.

Single Zener Diodes Part Context

This part belongs to the extensive 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a wide selection of voltages ranging from 2.4 V to 200 V. Variants are available with tighter tolerances or military screening levels using specific prefixes and suffixes.

Single Zener Diodes Replacement Considerations

Equivalent parts include MSP1N5236A-1TR and other JEDEC registered 1N5236 variants. Verify package compatibility and tolerance requirements before substitution.
