1N5529/TR

Overview

The Microchip Technology 1N5529/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 9.1 V with a tolerance of ±20%. The device has a maximum power dissipation of 500 mW and operates within a temperature range of -65 °C to +175 °C. It utilizes the DO-204AH (DO-35) axial through-hole package.

Feature Summary

• Provides stable voltage regulation at a nominal 9.1 V level
• Capable of handling up to 500 mW of power dissipation
• Engineered for operation in extreme temperatures from -65 °C to +175 °C

Applications

• Voltage reference circuits
• Overvoltage protection
• General-purpose voltage regulation

Procurement Notes

Verify that the specific part number matches the required Zener voltage and tolerance specifications. Confirm the package type is DO-204AH (DO-35) for through-hole mounting. Ensure the operating temperature range meets the environmental requirements of the target application. Check datasheet details for dynamic impedance and test current parameters.

Selection Notes

Select this component when a standard 9.1 V Zener diode is required for general voltage regulation tasks. The wide operating temperature range makes it suitable for harsh environments. Consider the ±20% tolerance if precise voltage clamping is not critical. Verify that the 500 mW power rating is sufficient for the expected current levels in the circuit design.

Part Context

This component belongs to Microchip's series of single Zener diodes. These devices are commonly used in electronic circuits to maintain a constant voltage across a load or to protect sensitive components from voltage spikes. The DO-35 package is a standard form factor for low-power diodes.

Replacement Considerations

Compatible substitutes include other 9.1 V Zener diodes with similar power ratings and package types, such as the 1N5529B-1/TR. Ensure any replacement maintains the required voltage tolerance and thermal performance characteristics.
