Overview
The onsemi 1N4750ATR is a single Zener diode with a nominal voltage of 27 V and a power dissipation rating of 1 W. It features a 5% voltage tolerance and operates within a temperature range of -65 °C to +200 °C. The device utilizes a DO-41 through-hole package and has a maximum reverse leakage current of 5 µA at the test current of 9.5 mA. Its Zener impedance is specified at 35 Ohms.
Feature Summary
- Provides stable voltage regulation for circuit protection applications
- Designed for through-hole mounting in standard PCB layouts
- Capable of operating across an extended industrial temperature range
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in power supply designs
- Clamping applications in signal conditioning paths
Procurement Notes
Verify that the specific part number suffix matches the required tape and reel packaging configuration, as bulk variants exist for this component family. Confirm RoHS compliance status directly from the manufacturer's latest documentation before finalizing procurement specifications. Ensure the ordering quantity aligns with the minimum order increment defined by the distributor or manufacturer for reel-based shipments.
Selection Notes
Select this component when a 27 V regulation point is required in a through-hole design. Consider the 1 W power rating and thermal management needs for the intended application environment. Verify that the DO-41 package dimensions fit the available board space and that the 5% tolerance meets the circuit's precision requirements.
Part Context
This component belongs to the 1N47 series of Zener diodes manufactured by onsemi. It shares electrical characteristics with other members of this series but is distinguished by its specific 27 V breakdown voltage and axial leaded package format. The 'ATR' suffix typically indicates a tape and reel packaging option suitable for automated assembly processes.
Replacement Considerations
Direct substitutes include the 1N4750A (bulk package) and 1N4750A-B from Rectron, which share identical electrical parameters. Ensure any replacement maintains the same DO-41 footprint and thermal performance capabilities.
