- Constructed for reliable operation across extended industrial temperature ranges
Applications
- Voltage reference circuits
- Overvoltage protection stages
- General-purpose voltage regulation
Procurement Notes
Verify specific suffix designations when ordering, as they determine packaging format such as bulk or tape and reel. Confirm RoHS compliance status for the exact part variant, as historical production runs may differ from current manufacturing standards. Ensure the selected package matches the intended PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component based on the required 5.6 V regulation point and 500 mW power rating. Evaluate the tolerance class needed for the application, as variants exist with different accuracy levels. Consider the thermal management capabilities of the DO-35 package relative to the expected operating environment and duty cycle.
Part Context
This component belongs to the standard 1N55xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage options within the same physical package form factor. These devices are widely used in discrete semiconductor designs requiring reliable voltage clamping or referencing.
Replacement Considerations
The 1N5524A and 1N5524D are parameter-equivalent substitutes within the same manufacturer lineup. Verify that the replacement variant meets the specific tolerance and impedance requirements of the original design.
