Overview
The Microchip Technology 1N4741P/TR12 is a silicon 1-watt Zener diode in the 1N4728AP through 1N4764AP series. It provides voltage regulation with a nominal Zener voltage of 11 V and a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features a plastic encapsulated DO-41 axial lead package. The 'TR' suffix indicates tape and reel packaging, while the 'P' designates plastic construction.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Features flexible axial-lead mounting terminals for standard PCB integration
- Constructed with a void-free transfer molded thermosetting epoxy body
Applications
- Voltage regulation circuits
- Reference voltage sources
- Overvoltage protection
Procurement Notes
Verify that the ordering suffix matches the required specifications. Confirm the 'TR' designation corresponds to tape and reel packaging requirements. Ensure the 'P' suffix aligns with the need for plastic encapsulation rather than glass body options. Cross-reference the part number against the manufacturer's latest documentation to confirm active status and compliance details.
Selection Notes
Select this component when a 1-watt power dissipation rating is required for voltage regulation applications. The plastic package offers lower thermal resistance compared to glass-body alternatives. Consider the specific Zener voltage and tolerance requirements to ensure compatibility with the target circuit design parameters.
Part Context
This component belongs to the popular 1N4728A through 1N4764A series of 1.0 watt Zeners. The series covers a voltage selection from 3.3 to 100 volts. These devices are JEDEC registered and available in various screening levels. The plastic version provides a distinct alternative to the traditional glass-body options found in the same family.
Replacement Considerations
Surface mount equivalents such as SMAJ4741A or MLL4741A are available. Consult the factory for other surface mount options if space constraints require a different form factor.
