Overview
The Panjit International Inc. 1N4750A_R2_00001 is a silicon Zener diode belonging to the 1W power series, housed in a molded plastic DO-41 axial lead package. It provides a nominal Zener voltage of 27V with a tolerance range of 25.65V to 28.35V at a test current of 9.5mA. The device features a maximum Zener impedance of 35 Ohms and a maximum leakage current of 0.1uA at 20.6V reverse voltage. Designed for high-temperature soldering up to 260°C for 10 seconds, it operates within a junction temperature range of -55°C to +200°C and complies with EU RoHS 2.0 standards.
Feature Summary
- Plastic package rated UL 94V-O for flame retardancy
- Axial leads guaranteed solderable per MIL-STD-750 Method 2026
- Lead-free construction compliant with EU RoHS 2.0
Applications
- Voltage regulation circuits
- Voltage reference applications
- Overvoltage protection
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packing type and quantity. Confirm that the component meets required environmental compliance standards for your region. Ensure the selected package variant matches your automated assembly or manual placement requirements before finalizing procurement orders.
Selection Notes
Select this component when a 27V Zener voltage is required in an axial through-hole configuration. Consider the 35 Ohm impedance limit for dynamic regulation needs. Verify thermal derating curves if operating near the maximum ambient temperature limits defined in the datasheet specifications.
Part Context
This part belongs to the 1N47xxA series of 1 Watt Zener diodes manufactured by Panjit International Inc. The series covers a wide voltage range from 3.3V to 68V. The R2 suffix typically indicates reel packaging, distinguishing it from bulk box or ammo box variants within the same electrical specification family.
Replacement Considerations
Cross-reference with other manufacturers' 1N4750A equivalents ensuring identical DO-41 package dimensions and 27V nominal voltage. Verify matching impedance and leakage current parameters for direct replacement in existing designs.
