Overview
The Central Semiconductor Corp 1N4701 TR PBFREE is a silicon Zener diode designed for low-level voltage regulation applications. It operates within the 1N4678 through 1N4717 series, featuring a nominal Zener voltage of 14 V with a tolerance range of 13.30 V to 14.70 V at a test current of 50 μA. The device supports a maximum power dissipation of 500 mW and a maximum regulator current of 17.5 mA. It exhibits a maximum reverse leakage current of 0.05 μA at 10.6 V and maintains an operating junction temperature range from -65 °C to +200 °C.
Feature Summary
- Designed for extremely low operating current requirements
- Features low leakage characteristics suitable for sensitive circuits
- Provides stable voltage regulation within specified tolerance limits
Applications
- Low-level voltage reference circuits
- Precision voltage regulation in low-power systems
- Protection against overvoltage in signal paths
Procurement Notes
Verify that the ordering suffix PBFREE confirms lead-free plating compliance as per manufacturer standards. Confirm the reel packaging configuration matches automated assembly requirements. Ensure the specific part number corresponds to the 14 V nominal voltage variant within the 1N4678-1N4717 series documentation.
Selection Notes
Select this component when circuit design demands minimal quiescent current consumption alongside precise voltage clamping. The DO-35 axial package facilitates through-hole mounting. Consider the maximum regulator current limit when sizing series resistors to ensure operation within the safe dissipation boundaries under all expected load conditions.
Part Context
This device belongs to the Central Semiconductor 1N4678 through 1N4717 series of silicon Zener diodes. The series covers a voltage range from 1.8 V to 43 V with consistent 5% tolerance. These components are engineered specifically for applications requiring low operating currents and low leakage, distinguishing them from higher-power general-purpose Zener variants.
Replacement Considerations
Cross-reference with other manufacturers offering 1N4701 specifications in DO-35 packages. Verify equivalent Zener voltage tolerances and maximum power dissipation ratings to ensure functional compatibility without redesigning the surrounding bias network.
