Overview
The Central Semiconductor Corp 1N4704 TR PBFREE is a silicon Zener diode designed for low-level applications requiring extremely low operating current and leakage. It features a nominal Zener voltage of 17 V with a 5% tolerance, tested at 50 μA. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +200°C. It utilizes the DO-35 axial leaded package.
Feature Summary
- Designed for applications requiring extremely low operating current (50μA) and low leakage.
- Features a 5% voltage tolerance for precise regulation in low-power circuits.
- Capable of operation across an extended temperature range from -65°C to +200°C.
Applications
- Low-level voltage reference circuits
- Precision voltage regulation
- Protection against overvoltage transients
Procurement Notes
Verify that the ordering suffix 'PBFREE' confirms lead-free plating as per manufacturer standards. Confirm the specific reel quantity requirements for tape-and-reel packaging. Ensure the DO-35 package dimensions align with the target PCB footprint. Cross-reference the marking code C4704 for physical identification during assembly.
Selection Notes
Select this component when circuit design demands minimal quiescent current draw alongside stable voltage regulation. The 500mW power rating suits low-current applications where higher wattage devices are unnecessary. Verify that the 17V nominal output matches the system's required reference level before integration.
Part Context
This part belongs to the 1N4678 through 1N4717 series of silicon Zener diodes manufactured by Central Semiconductor. The series covers a voltage range from 1.8V to 43V, all sharing the same 500mW power dissipation capability and DO-35 package style. These devices are standardized for general-purpose low-level voltage regulation tasks.
Replacement Considerations
Substitute parts must match the 17V nominal Zener voltage, 500mW power rating, and DO-35 package. Verify equivalent leakage current specifications and thermal resistance characteristics to ensure functional compatibility in the existing circuit design.
