1N4759A TR TIN/LEAD

Overview

The 1N4759A TR TIN/LEAD is a silicon Zener diode manufactured by Central Semiconductor Corp, designed for voltage regulation applications. It features a nominal Zener voltage of 62 V with a tolerance of ±5%. The device operates in the DO-41 axial through-hole package and dissipates up to 1 W of power at 50°C ambient temperature. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 125 Ω at a test current of 4 mA. The component supports an operating junction temperature range from -65°C to +200°C.

Feature Summary

• Hermetically sealed glass construction utilizing double slug type metallurgically bonded design for enhanced reliability.
• Oxide passivated die structure providing stable voltage regulation performance across wide temperature ranges.
• Axial leaded DO-41 package configuration suitable for standard through-hole mounting processes.

Applications

• Industrial voltage regulation circuits
• Commercial equipment power supplies
• Entertainment system electronics
• Computer application logic protection

Procurement Notes

Verify the specific suffix 'TR TIN/LEAD' against official datasheets to confirm tape-and-reel packaging and tin/lead plating specifications. Ensure compliance with RoHS directives if required, as this variant may not meet lead-free standards. Cross-reference manufacturer part numbers to distinguish between bulk and reel configurations. Confirm availability status directly with Central Semiconductor or authorized distributors prior to ordering.

Selection Notes

Select this component when a precise 62 V reference is required within the 1N47 series family. The DO-41 package offers robust mechanical stability for high-temperature environments up to 200°C. Consider the 125 Ω impedance value for noise-sensitive applications where lower dynamic resistance might be necessary. Verify that the 1 W power dissipation rating aligns with the thermal management capabilities of the target circuit board layout.

Part Context

This part belongs to the 1N4728A through 1N4764A series of one-watt silicon Zener diodes produced by Central Semiconductor. The series covers a voltage range from 3.3 V to 100 V with consistent 5% tolerance. These devices are engineered for general-purpose regulation tasks requiring high reliability and hermetic sealing in harsh industrial and commercial environments.

Replacement Considerations

Equivalent parts include the 1N4759A BK TIN/LEAD from Central Semiconductor and the 1N4759ARL from Motorola/NXP. Verify pinout compatibility and package dimensions (DO-41) before substitution. Ensure replacement components match the 62 V Zener voltage and 1 W power dissipation ratings.
