Overview
The Microchip Technology 1N4757AE3/TR13 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 51V with a tolerance of 5%. The device is rated for a power dissipation of 1W and utilizes the DO-204AL (DO-41) axial through-hole package. It operates within a temperature range of -65°C to +150°C and is moisture sensitivity level 1 compliant.
Feature Summary
- Provides stable voltage regulation across a broad operating range
- Utilizes plastic encapsulation for environmental protection
- Offers low thermal resistance compared to glass-body options
Applications
- General voltage regulation circuits
- Reference voltage sources
- Overvoltage protection in low-power systems
Procurement Notes
Verify the specific suffix 'e3' confirms RoHS compliance and lead-free status as per manufacturer documentation. Confirm the 'TR13' designation indicates reel packaging requirements. Ensure the DO-41 package dimensions match the target PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a 51V regulation point is required with standard 5% tolerance. The 1W power rating suits moderate current applications. Consider the axial DO-41 package for through-hole assembly processes. Verify that the operating temperature range meets the specific environmental conditions of the end application.
Part Context
This part belongs to the popular 1N4728AP through 1N4764AP series of 1.0 watt Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series provides extensive voltage selection from 3.3 to 100 volts. These devices are JEDEC registered and available in RoHS-compliant versions with the 'e3' suffix.
Replacement Considerations
Surface mount equivalents such as SMAJ4757A or MLL4757A are available from the same manufacturer family. Direct pin-compatible replacements may require verification of power ratings and package dimensions.
