Overview
The 1N4768A/TR is a single Zener diode manufactured by Microchip Technology, designed for through-hole mounting in DO-204AH (DO-35) packages. It features a nominal Zener voltage of 9.1 V with a tolerance of ±5%. The device has a power dissipation rating of 500 mW and a maximum reverse leakage current of 10 µA. Operating temperatures range from -65 °C to +175 °C. The component utilizes a glass axial leaded construction.
Feature Summary
- Temperature compensated design for stable voltage regulation across varying thermal conditions
- Single unidirectional configuration for precise reference applications
- Glass axial package suitable for high-temperature environments up to 175 °C
Applications
- Voltage reference circuits requiring temperature stability
- Overvoltage protection in low-power electronic systems
- Clamping applications in signal conditioning paths
Procurement Notes
Verify the specific suffix /TR indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status directly with Microchip Technology as datasheets may vary by revision. Ensure the DO-204AH footprint matches your PCB layout requirements before finalizing procurement.
Selection Notes
Select this component when a 9.1 V regulated reference is needed with tight tolerance. The 500 mW rating suits low-current applications. Verify that the through-hole DO-35 package fits the assembly process. Consider the 175 °C max operating temperature for harsh environment deployments.
Part Context
This part belongs to the standard 1N47xx series of Zener diodes produced by Microchip Technology. These components are widely used for basic voltage regulation tasks. The /TR suffix denotes reel packaging for automated insertion. The series offers various voltage options within the same physical package form factor.
Replacement Considerations
Check for equivalent parts from other manufacturers offering 9.1 V Zener diodes in DO-35 packages. Ensure replacement devices match the 500 mW power dissipation and ±5% voltage tolerance specifications.
