1N4627 TR PBFREE

Overview

The Central Semiconductor Corp 1N4627 TR PBFREE is a silicon Zener diode designed for low leakage, low current, and low noise applications. It operates within the 1N4614 through 1N4627 series, featuring a nominal Zener voltage of 6.2 V with a 5% tolerance range from 5.890 V to 6.510 V at a test current of 250 µA. The device has a maximum power dissipation of 250 mW and supports junction temperatures from -65°C to +200°C. It utilizes a DO-35 axial leaded package.

Feature Summary

• Engineered for low leakage and low noise performance suitable for sensitive circuits
• Provides stable voltage regulation with tight 5% tolerance across the operating temperature range
• Capable of high thermal stability with an extended junction temperature rating up to +200°C

Applications

• Low noise voltage reference circuits
• Precision low current regulation applications
• Sensitive analog signal conditioning stages

Procurement Notes

Verify that the ordering suffix PBFREE confirms lead-free plating compliance as specified in manufacturer documentation. Confirm the TR designation indicates tape and reel packaging if automated assembly is required. Ensure the DO-35 package style matches the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when specific low noise characteristics are critical for circuit performance. The 250 mW power rating limits suitability for high-power regulation tasks. Verify that the 6.2 V nominal voltage aligns with system design constraints. Consider the DO-35 package dimensions for mechanical integration into the target enclosure or board layout.

Part Context

This part belongs to the 1N4614 through 1N4627 series of silicon Zener diodes manufactured by Central Semiconductor Corp. The series covers voltages from 1.8 V to 6.2 V. These devices share common electrical characteristics including low leakage and low noise profiles, differentiated primarily by their specific Zener voltage ratings and corresponding marking codes.

Replacement Considerations

Cross-reference other manufacturers' 1N4627 equivalents to ensure matching Zener voltage, power dissipation, and package compatibility.
