Overview
The Central Semiconductor Corp 1N4707 TR TIN/LEAD is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 20 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and utilizes the DO-41 axial through-hole package. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 13.7 V, a Zener impedance of 22 Ω, and a test current of 12.5 mA. The component operates within a temperature range of -65°C to +200°C junction temperature.
Feature Summary
- Provides stable voltage regulation using a single silicon Zener junction.
- Features an internally metallurgical bond suitable for robust performance.
- Utilizes a glass-encapsulated DO-41 axial leaded package for through-hole mounting.
Applications
- General purpose voltage regulation circuits
- Reference voltage sources in electronic systems
- Overvoltage protection stages
Procurement Notes
Verify that the specific ordering suffix matches the required termination plating and packaging format. Confirm RoHS compliance status as tin/lead variants may differ from lead-free specifications. Ensure the manufacturer designation aligns with Central Semiconductor Corp requirements for the intended supply chain. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.
Selection Notes
Select this component when a 20 V regulation point is required in a standard through-hole configuration. The 1 W power rating supports moderate current loads compared to lower-power surface mount alternatives. Verify that the circuit design accommodates the specified Zener impedance and leakage current limits under expected operating conditions.
Part Context
This part belongs to the 1N47 series of general-purpose Zener diodes manufactured by Central Semiconductor. The series offers a wide range of voltage values in the DO-41 package. These components are commonly used in industrial and commercial electronics where reliable axial-leaded regulation is necessary.
Replacement Considerations
Equivalent parts include 1N4747A from onsemi and Taiwan Semiconductor. Verify pinout compatibility and thermal management requirements when substituting manufacturers.
