Overview
The onsemi 1N4736A-T50R is a single Zener diode with a nominal voltage of 6.8 V and a power dissipation rating of 1 W. It features a ±5% tolerance and operates within a temperature range of -65 °C to +200 °C. The device utilizes a DO-41 axial through-hole package and has a maximum reverse leakage current of 10 µA. Test conditions specify a Zener test current of 37 mA, with a Zener impedance of 3.5 Ohms.
Feature Summary
- Provides stable voltage regulation at 6.8 V for circuit protection applications
- Capable of handling 1 W power dissipation in a robust axial leaded package
- Operates reliably across an extended industrial temperature range up to 200 °C
Applications
- Voltage reference circuits requiring precise 6.8 V levels
- Overvoltage protection in power supply inputs
- Clamping applications in signal conditioning paths
Procurement Notes
Verify the component status carefully as this part may be subject to end-of-life restrictions or last-time buy notifications from the manufacturer. Confirm that the DO-41 package dimensions align with your PCB footprint requirements. Ensure that the 1 W power rating is sufficient for your specific thermal environment and duty cycle calculations before finalizing procurement decisions.
Selection Notes
Select this component when a standard 6.8 V Zener voltage is required with high thermal stability. The DO-41 package offers reliable through-hole mounting for general-purpose electronics. Consider the 3.5 Ohm impedance for low-noise applications. Verify that the 1 W power rating meets the peak dissipation needs of your design without excessive derating.
Part Context
This component belongs to the 1N47xx series of Zener diodes manufactured by onsemi. These devices are widely used for voltage regulation and protection. The T50R suffix indicates a tape and reel packaging format suitable for automated assembly processes. The series is known for consistent performance in standard electronic applications.
Replacement Considerations
Compatible substitutes include the 1N4736A and 1N4736ATR from onsemi, which share identical electrical specifications. Other manufacturers producing JEDEC-compliant 1N4736A parts in DO-41 packages may also serve as functional replacements if pinout and thermal characteristics match.
