1N4626 TR PBFREE

Overview

The Central Semiconductor Corp 1N4626 TR PBFREE is a silicon Zener diode in the DO-35 axial leaded package. It provides a nominal Zener voltage of 5.6 V with a 5% tolerance range from 5.320 V to 5.880 V. The device dissipates 250 mW at 25°C and operates within a junction temperature range of -65°C to +200°C. Key electrical parameters include a maximum reverse current of 10 µA at 4.0 V, a maximum Zener impedance of 1400 Ω at 250 µA, and a noise density of 4.0 µV/√Hz at 250 µA.

Feature Summary

• Designed for low leakage, low current, and low noise applications
• Features a standard DO-35 case configuration for axial mounting
• Marked with prefix 'C' followed by the full part number or specific marking code

Applications

• Low noise reference circuits
• Precision voltage regulation
• Low current protection stages

Procurement Notes

Verify the exact ordering suffix against manufacturer documentation to confirm plating options and packaging format. Confirm that the TR designation aligns with the required reel quantity and handling specifications for your assembly process. Ensure compliance with RoHS directives if applicable to your manufacturing standards.

Selection Notes

Select this component when a stable 5.6 V reference is required with strict low-noise constraints. The DO-35 package suits through-hole designs requiring robust axial leads. Evaluate the high Zener impedance value to ensure it meets the dynamic regulation requirements of your specific circuit topology.

Part Context

This part belongs to the 1N4614 through 1N4627 series of low-noise silicon Zener diodes. The series covers voltages from 1.8 V to 6.2 V, all sharing the same 250 mW power dissipation rating and DO-35 mechanical outline. These devices are engineered specifically for applications demanding minimal electrical noise and low operating currents.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4626 equivalents in the DO-35 package. Verify that substitute parts match the 5.6 V nominal voltage, 250 mW power rating, and low-noise characteristics to maintain circuit performance integrity.
