Overview
The 1N4741A-T is a silicon planar Zener diode manufactured by Diodes Incorporated, housed in a DO-41 glass axial package. It provides an 11V nominal Zener voltage with a standard tolerance of ±5%. The device supports a maximum power dissipation of 1W at 25°C ambient temperature and operates within a junction temperature range of -65°C to +175°C. Electrical characteristics include a maximum dynamic impedance of 8Ω at the test current of 23mA and a reverse leakage current of 5µA at 8.4V.
Feature Summary
- Utilizes a glass passivated silicon planar construction for stable voltage regulation
- Features a DO-41 axial leaded package designed for through-hole mounting applications
- Compliant with RoHS directives and offers a lead-free finish
Applications
- Voltage stabilization circuits
- Voltage reference sources
- Overvoltage protection networks
Procurement Notes
Verify component authenticity against official datasheet specifications before integration. Confirm that the specific ordering suffix matches the required packaging format. Ensure compliance with environmental regulations relevant to the target market. Validate thermal management requirements based on actual operating conditions rather than absolute maximum ratings alone.
Selection Notes
Select this component when a precise 11V reference is required in a standard axial package. Consider the thermal resistance characteristics if operating near maximum power limits. Evaluate the impedance profile against circuit sensitivity requirements. Verify availability as the product may be subject to discontinuation notices.
Part Context
This part belongs to the 1N4728A through 1N4761A series of 1.0 Watt Zener diodes produced by Diodes Incorporated. The series covers a wide voltage range from 3.3V to 75V. The '-T' suffix specifically denotes the Tape and Reel packaging configuration, distinguishing it from the Ammo Pack variant.
Replacement Considerations
Diodes Incorporated recommends using the DFLZxx series for new designs instead of this legacy component. Cross-reference with other manufacturers offering identical DO-41 packaged 11V Zener diodes if supply constraints exist.
