1N4702 BK PBFREE

Overview

The Central Semiconductor Corp 1N4702 BK PBFREE is a silicon Zener diode designed for low-level applications requiring extremely low operating current and leakage. It features a nominal Zener voltage of 15 V with a 5% tolerance, tested at a current of 50 μA. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +200°C. It utilizes the DO-35 axial leaded case and includes a maximum reverse leakage current of 0.05 μA.

Feature Summary

• Designed for applications requiring extremely low operating current and low leakage
• Features a 5% voltage tolerance for precise regulation
• Capable of operation across an extended temperature range

Applications

• Low-level voltage reference circuits
• Precision voltage regulation
• Circuits requiring minimal quiescent current consumption

Procurement Notes

Verify that the ordering suffix 'BK' corresponds to the specific bulk packaging configuration required by the procurement specification. Confirm that the 'PBFREE' designation aligns with environmental compliance requirements for lead-free plating as defined in the manufacturer's standard terms. Ensure the component meets the necessary RoHS standards before finalizing the purchase order.

Selection Notes

Select this component when circuit design demands a stable 15 V reference with minimal power draw. The 500 mW power rating allows for moderate current handling in series configurations. Verify that the DO-35 package dimensions fit the available board space and that the through-hole mounting method is compatible with the assembly process.

Part Context

This part 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 sharing the same 500 mW power dissipation capability and DO-35 mechanical outline. This specific model represents the mid-range voltage option within the family.

Replacement Considerations

Substitute parts must match the 15 V nominal Zener voltage, 500 mW power rating, and DO-35 package. Verify that alternative manufacturers offer equivalent 5% tolerance and similar leakage characteristics to ensure circuit performance remains unchanged.
