1N4709 TR PBFREE

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4709 TR PBFREE is a silicon Zener diode designed for low-level applications requiring extremely low operating current and leakage. It operates within the 1N4678 through 1N4717 series, featuring a 5% voltage tolerance and a maximum power dissipation of 500 mW at 75°C ambient temperature. The nominal Zener voltage is 24 V, with a test current of 50 μA. Maximum reverse leakage current is specified at 0.01 μA at 18.2 V. The device supports a maximum regulator current of 9.9 mA and functions across a junction temperature range of -65°C to +200°C.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required plating configuration. The 'PBFREE' designation indicates lead-free plating compliance. Confirm the package type corresponds to DO-35 requirements for your assembly process. Ensure the manufacturer part number aligns exactly with the datasheet specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when circuit design demands low Zener test currents around 50 μA. The 500 mW power rating suits moderate power dissipation needs. Verify that the 24 V nominal voltage fits the target regulation requirement. Consider the DO-35 axial package constraints for board layout and thermal management during the selection phase.

Single Zener Diodes Part Context

This component belongs to the 1N4678 through 1N4717 series of low-level silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers a voltage range from 1.8 V to 43 V. All devices in this family share identical mechanical outlines and maximum ratings, differing primarily in their specific Zener voltage breakdown points and corresponding marking codes.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N4709 variants meeting the same electrical specifications. Ensure replacement parts maintain the 500 mW power rating and DO-35 package dimensions. Verify that alternative sources provide equivalent leakage current and voltage tolerance data.
