Overview
The Central Semiconductor Corp 1N4702 TR TIN/LEAD is a silicon planar Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 4.7 V with a 5% tolerance, housed in the DO-41 axial through-hole package. The device supports a maximum power dissipation of 1 W at an ambient temperature of 50°C, reducing linearly to 0.67 W at 100°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 3.6 V and a maximum Zener impedance of 8 Ω at the test current of 53 mA. The component operates within a junction temperature range of -65°C to +200°C.
Feature Summary
- Utilizes silicon planar technology for stable voltage regulation performance.
- Provides precise voltage referencing with a tight 5% tolerance band.
- Engineered for high thermal stability with a maximum junction temperature of 200°C.
Applications
- Voltage regulation circuits
- Voltage reference sources
- Overvoltage protection
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm lead-free status and packaging configuration. Ensure the requested variant matches the required RoHS compliance level and tape-and-reel specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before finalizing procurement orders.
Selection Notes
Select this component when a 4.7 V regulated supply is required in a standard axial package. Evaluate the 1 W power rating against expected thermal loads to ensure operation remains within derating curves. Confirm that the 8 Ω impedance meets the noise and stability requirements of the target application circuit.
Part Context
This part belongs to the 1N47xx series of axial leaded Zener diodes manufactured by Central Semiconductor. These components are widely used in general-purpose electronics for basic voltage clamping and regulation tasks. The series offers various voltage options within the same mechanical footprint, facilitating design flexibility across different product lines.
Replacement Considerations
Consult official substitution guides for equivalent parts from other manufacturers. Verify pinout compatibility and thermal characteristics when replacing with alternative suppliers' offerings.
