Overview
The Microchip Technology 1N4755APE3/TR8 is a silicon 1.0-watt Zener diode housed in a plastic DO-41 (DO-204AL) axial lead package. It provides voltage regulation with a nominal Zener voltage of 43V and a standard tolerance of +/- 5%. The device operates within an ambient temperature range of -65°C to +150°C and features RoHS compliant annealed matte-tin plating on its terminals.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Features flexible axial-lead mounting terminals for through-hole applications
- Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
- Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020
Applications
- Voltage regulation circuits requiring 1W power dissipation
- General purpose electronic equipment utilizing axial lead components
- Temperature compensated reference designs within specified ranges
Procurement Notes
Verify the specific suffix configuration against official datasheets to confirm material composition and compliance status. Ensure that ordering requirements match the manufacturer's tape and reel specifications. Confirm that the component meets all relevant environmental regulations applicable to your region before finalizing procurement decisions.
Selection Notes
Select this component when a 43V regulation point is required with 5% tolerance. Consider the 1W power rating and thermal resistance characteristics for heat management. Verify compatibility with existing PCB layouts designed for DO-41 packages and ensure operating temperatures remain within the specified -65°C to +150°C range.
Part Context
This part belongs to the 1N4728AP through 1N4764AP series of silicon Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series offers extensive voltage selection from 3.3 to 100 volts in plastic encapsulated packages. These devices are JEDEC registered and provide a lower thermal resistance compared to glass-body options.
Replacement Considerations
Equivalent parts include other manufacturers' 1N4755A variants in DO-41 packages. Verify electrical parameters such as Zener voltage, tolerance, and power dissipation match the original design requirements before substitution.
