1N4618 TR TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4618 TR TIN/LEAD is a single silicon Zener diode designed for through-hole mounting in the DO-35-2 axial leaded package. It features a nominal Zener voltage of 2.7 V with a 5% tolerance and a maximum power dissipation of 250 mW. Key electrical characteristics include a maximum reverse leakage current of 1.0 µA, a Zener impedance of 1500 ohms, and a test current of 250 µA. The device operates within a junction temperature range of -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a low 2.7 V reference level
• Engineered for high thermal stability with an extended operating temperature range up to 200°C
• Constructed using silicon technology for reliable performance in axial leaded configurations

Single Zener Diodes Applications

• Low-voltage reference circuits requiring precise 2.7 V levels
• Voltage regulation in compact through-hole electronic assemblies
• Overvoltage protection for sensitive low-voltage components

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix corresponds to the tin/lead plating requirement, as this affects material compliance and solderability specifications. Confirm the reel packaging designation matches automated assembly needs. Ensure the selected variant aligns with RoHS or non-RoHS project constraints based on the exact part number suffix provided by the manufacturer.

Single Zener Diodes Selection Notes

Select this component when a low-voltage Zener reference is required in a standard axial package. The 250 mW power rating suits low-current applications where higher dissipation is unnecessary. Verify that the 1500 ohm impedance meets the noise and regulation requirements of the target circuit design compared to lower impedance alternatives.

Single Zener Diodes Part Context

This component belongs to the 1N4618 series of small-signal Zener diodes manufactured by Central Semiconductor. The series utilizes standard DO-35 axial packages suitable for general-purpose through-hole electronics. The tin/lead finish indicates a specific plating option distinct from lead-free variants within the same electrical specification family.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 2.7 V Zener voltage, 250 mW power rating, and DO-35 package dimensions. Verify compatibility with the 1500 ohm impedance and 1.0 µA leakage current limits to ensure equivalent circuit performance.
