Overview
The Microchip Technology 1N4741APE3/TR8 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, housed in a plastic DO-41 (DO-204AL) axial-lead package. 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 maximum dynamic impedance of 8 Ohms at a test current of 23 mA. It includes RoHS compliance via the 'e3' suffix and tape-and-reel packaging indicated by the 'TR' suffix.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Features flexible axial-lead mounting terminals for standard circuit integration
- 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 in power supply circuits
- Reference voltage generation in electronic systems
- Overvoltage protection applications
Procurement Notes
Verify that the ordering suffixes correspond to specific physical and electrical attributes. The 'P' suffix indicates plastic construction, while the 'e3' suffix confirms RoHS compliance. The 'TR' suffix designates tape-and-reel packaging. Confirm these identifiers match project requirements before procurement to ensure correct material composition and handling specifications.
Selection Notes
Select this component when a 11 V regulated reference is required in an axial-lead format. Ensure the application stays within the 1.0-watt power dissipation limit at 25°C lead temperature. Consider the thermal resistance characteristics if mounting on FR4 PCBs. Verify that the ±5% voltage tolerance meets the circuit precision requirements compared to tighter tolerance options.
Part Context
This part belongs to the JEDEC registered 1N4728A through 1N4764A series of 1.0-watt Zener diodes. The series offers an extensive voltage selection from 3.3 to 100 volts. The plastic encapsulated version provides lower thermal resistance compared to glass-body options. Surface mount equivalents are available in SMAJ and MLL packages for different form factor needs.
Replacement Considerations
Surface mount equivalents include SMAJ4741A and MLL4741A. Glass-body versions exist under the same JEDEC numbering but require separate datasheet verification.
