Overview
The onsemi 1N4736ATR is a single-channel general-purpose Zener diode with a nominal voltage of 6.8 V and a maximum power dissipation of 1 W. It features a 5% tolerance, 5 Ω maximum impedance, and 10 μA reverse leakage current. The device operates within a temperature range of -65°C to 200°C and is housed in a DO-41 through-hole package.
Feature Summary
- Provides stable voltage regulation at a nominal 6.8 V reference point
- Designed for high thermal stability with an operating junction temperature up to 200°C
- Utilizes a robust glass axial leaded package for reliable through-hole mounting
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in electronic systems
- Clamping applications for signal conditioning
Procurement Notes
Verify the specific manufacturer designation, as the 1N4736A series is produced by multiple vendors including Vishay and Microchip. Confirm that the requested component matches the exact electrical specifications and package dimensions required for your design. Ensure compliance with relevant environmental standards such as RoHS before finalizing procurement orders.
Selection Notes
Select this component when a standard 6.8 V regulation point is needed in a through-hole configuration. Consider the 1 W power rating and 5% tolerance for circuit accuracy requirements. Evaluate the thermal management capabilities given the wide operating temperature range and the specific impedance characteristics at the test current.
Part Context
This part belongs to the widely recognized 1N47xxA series of silicon Zener diodes. These components are industry-standard devices used extensively in discrete electronics for basic voltage regulation tasks. The 1N4736A variant specifically targets the 6.8 V segment of this popular family.
Replacement Considerations
Direct substitutes include Vishay 1N4736A-TR and Microchip 1N4736Pe3/TR8. Verify pinout compatibility and ensure the alternative supplier's datasheet confirms identical voltage and power ratings.
