Overview
The Microchip Technology 1N4755CPE3/TR12 is a silicon 1.0-watt Zener diode housed in a plastic DO-41 axial lead package. It provides voltage regulation with a nominal Zener voltage of 43 volts and a tight tolerance of plus or minus 2 percent. The device operates within an ambient temperature range of -65°C to +150°C and features RoHS compliant annealed matte-tin plating.
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 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 precise tolerance
- Power supply reference voltage generation
- Overvoltage protection in electronic systems
Procurement Notes
Verify the specific suffix configuration against official datasheets to confirm tolerance, packaging, and compliance status. Ensure the ordering suffix matches the required electrical characteristics and mechanical form factor for your design implementation.
Selection Notes
Select this component when a 43-volt regulation point with high precision is required. The plastic construction offers lower thermal resistance compared to glass-body options. Verify that the 1-watt power dissipation rating aligns with the thermal management capabilities of the target circuit board layout.
Part Context
This part belongs to the 1N4728AP thru 1N4764AP series of 1.0-watt Zener diodes manufactured by Microsemi (now Microchip). The series covers a voltage selection from 3.3 to 100 volts. The 'C' suffix indicates a tighter 2% voltage tolerance, while the 'P' suffix denotes plastic encapsulation.
Replacement Considerations
Compatible substitutes include other 1N4755 variants with matching 43V ratings and 2% tolerance, such as 1N4755Ae3 or equivalent JEDEC registered parts from other manufacturers offering identical DO-41 plastic packages.
