1N4715 BK PBFREE

Overview

The Central Semiconductor Corp 1N4715 BK 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 nominal Zener voltage of 36 V with a tolerance of ±5%. The device dissipates up to 500 mW at an ambient temperature of 75°C and maintains operation across a junction temperature range of -65°C to +200°C. Electrical characteristics include a maximum reverse leakage current of 0.01 μA at 27.3 V and a test current of 50 μA.

Feature Summary

• Designed for applications requiring extremely low operating current and low leakage
• Maintains stable voltage regulation with a tight 5% tolerance
• Capable of handling high junction temperatures up to 200°C

Applications

• Low-level voltage reference circuits
• Precision voltage regulation in sensitive electronics
• Protection against overvoltage transients in low-power systems

Procurement Notes

Verify that the ordering suffix 'PBFREE' confirms lead-free plating compliance as specified by the manufacturer. Ensure the 'BK' designation aligns with bulk packaging requirements if applicable. Cross-reference the specific marking code C4715 on the component body to confirm authenticity and correct part identification before integration into production.

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 500 mW power dissipation limit relative to thermal management constraints in the final assembly environment.

Part Context

This device 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 common mechanical outlines and electrical testing standards defined in the official datasheet.

Replacement Considerations

Direct substitutes must match the 36 V nominal Zener voltage, 500 mW power rating, and DO-35 package. Verify that alternative manufacturers provide equivalent leakage currents and tolerance specifications to ensure circuit performance parity.
