Overview
The Central Semiconductor Corp 1N4704 TR TIN/LEAD is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 6.8 V with a 5% tolerance and operates in the DO-201 axial leaded package. The device supports a maximum power dissipation of 5 W and withstands reverse currents up to 100 µA at specified voltages. It includes a low Zener impedance of 1 Ohm and functions reliably across an extended temperature range from -65°C to +200°C, making it suitable for robust industrial environments.
Feature Summary
- Provides stable voltage regulation through precise Zener breakdown characteristics
- Capable of handling high power dissipation for demanding circuit loads
- Engineered for reliable operation across extreme temperature variations
Applications
- High-power voltage reference circuits
- Overvoltage protection systems
- Industrial power supply regulation
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm tin/lead composition and reel packaging details. Ensure compatibility with existing thermal management designs due to the 5 W power rating. Confirm RoHS status requirements as tin/lead variants may differ from lead-free equivalents. Validate that the DO-201 package dimensions fit the target PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when high power handling and wide temperature stability are required. The 6.8 V output suits specific reference needs compared to standard lower voltage options. Consider the DO-201 package size for adequate heat dissipation without external heatsinks in moderate duty cycles. Verify current limits against load requirements to ensure safe operating area compliance during peak conditions.
Part Context
This part belongs to the 1N47xx series of Zener diodes manufactured by Central Semiconductor. It shares the fundamental regulatory function with other series members but distinguishes itself through higher power capabilities and specific voltage ratings. The tin/lead variant offers traditional soldering characteristics for legacy or specific manufacturing processes requiring non-lead-free materials.
Replacement Considerations
Cross-reference with other manufacturers offering 5 W, 6.8 V Zener diodes in DO-201 packages. Verify pinout compatibility and thermal resistance values to ensure direct substitution. Check if lead-free alternatives meet environmental regulations if tin/lead is no longer permitted.
