Overview
The Central Semiconductor Corp 1N4708 BK PBFREE is a low-level silicon Zener diode designed for applications requiring extremely low operating current and low leakage. It features a nominal Zener voltage of 22 V with a 5% tolerance, tested at 50 μA. The device operates within a junction temperature range of -65°C to +200°C and dissipates up to 500 mW. It utilizes the DO-35 axial leaded package.
Feature Summary
- Designed for low-level applications requiring extremely low operating current (50μA) and low leakage characteristics.
- Provides stable voltage regulation with a tight 5% tolerance on the nominal Zener voltage.
- Capable of operation across an extended temperature range from -65°C to +200°C.
Applications
- Low-power voltage reference circuits
- Precision voltage regulation in sensitive electronics
- Protection against overvoltage transients in low-current systems
Procurement Notes
Verify the specific ordering suffix 'BK' and 'PBFREE' directly with the manufacturer or authorized distributors to ensure compliance with RoHS standards and packaging requirements. Confirm that the DO-35 package dimensions match your PCB layout constraints before finalizing procurement decisions.
Selection Notes
Select this component when circuit design demands minimal quiescent current consumption alongside precise voltage clamping. Ensure the maximum regulator current of 10.8 mA aligns with the available bias current in your application to maintain accurate voltage regulation without exceeding power dissipation limits.
Part Context
This part belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes manufactured by Central Semiconductor. The series covers a voltage range from 1.8 V to 43 V, all sharing similar low-leakage characteristics and the DO-35 axial package form factor for through-hole mounting.
Replacement Considerations
Cross-reference with other manufacturers offering 1N4708 specifications in DO-35 packages. Verify that substitute parts meet the same 50 μA test current requirement and 5% tolerance to ensure functional equivalence in low-current designs.
FAQ
What is the maximum reverse leakage current for the 1N4708?
The maximum reverse leakage current is 0.01 μA at the specified reverse voltage.
How is the Zener voltage defined for this component?
The Zener voltage is nominally 22 V, measured at a test current of 50 μA, with a tolerance range of 20.90 V to 23.10 V.
