Overview
The 1N4758AE3/TR13 is a Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 56 V with a tolerance of +/- 5%. The device operates in the DO-204AL (DO-41) axial package and supports through-hole mounting. It has a power dissipation rating of 1 W and a maximum reverse leakage current of 5 uA. The component functions within a temperature range of -65°C to +150°C and exhibits a maximum Zener impedance of 110 Ohms.
Feature Summary
- Provides stable voltage regulation at a nominal 56 V level
- Capable of handling 1 W power dissipation in an axial leaded package
- Operates reliably across an extended industrial temperature range
Applications
- Voltage reference circuits requiring 56 V stability
- Overvoltage protection in DC power systems
- General-purpose voltage regulation in electronic assemblies
Procurement Notes
Verify the specific suffix TR13 indicates reel packaging when reviewing distributor listings. Confirm RoHS compliance status via the official datasheet as regulatory requirements may vary by region. Ensure the DO-41 package dimensions match your PCB footprint constraints before finalizing procurement decisions.
Selection Notes
Select this component when a 56 V Zener voltage is required with 1 W power handling capability. The DO-41 axial package suits through-hole designs. Consider the 110 Ohm impedance limit for dynamic regulation needs. Verify that the operating temperature range meets the environmental conditions of the target application.
Part Context
This part belongs to the 1N47xx series of Zener diodes produced by Microchip Technology. The 'E3' suffix typically denotes lead-free composition, while 'TR13' specifies tape and reel packaging. These diodes are standard components for basic voltage regulation tasks in consumer and industrial electronics.
Replacement Considerations
Direct substitutes include other 56 V, 1 W Zener diodes in the DO-41 package from manufacturers such as ON Semiconductor or Vishay. Ensure replacement parts match the 5% voltage tolerance and 110 Ohm impedance specifications to maintain circuit performance.
