1N4625 BK TIN/LEAD

Overview

The Central Semiconductor Corp 1N4625 BK TIN/LEAD is a Zener diode with a nominal voltage of 10 V and a power dissipation rating of 500 mW. It features a 5% voltage tolerance and operates within a temperature range of -65 °C to +200 °C. The device utilizes a DO-35-2 through-hole package and has a maximum reverse leakage current of 5 µA. Its Zener impedance is specified at 70 ohms, with a test current of 50 mA.

Feature Summary

• Provides stable voltage regulation in the low-voltage range via Zener breakdown mechanism.
• Supports high-temperature operation up to 200 °C for demanding environments.
• Utilizes a glass-passivated junction for reliable performance.

Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping applications

Procurement Notes

Verify the specific suffix 'BK TIN/LEAD' against the manufacturer's official datasheet to confirm lead composition and marking details. Ensure the procurement channel provides valid traceability documentation. Confirm RoHS compliance status as tin/lead variants may differ from standard specifications.

Selection Notes

Select this component when a 10 V Zener reference is required in a compact DO-35 package. Evaluate the 500 mW power dissipation limit against circuit load requirements. Consider the 70 ohm impedance for noise sensitivity in precision analog designs.

Part Context

This part belongs to the 1N46xx series of glass-passivated Zener diodes manufactured by Central Semiconductor. These components are designed for general-purpose voltage regulation and protection tasks. The series offers various voltage options within a standardized axial-leaded form factor suitable for through-hole mounting.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4625 equivalents. Verify that substitute parts match the 10 V nominal voltage, 500 mW power rating, and DO-35 package dimensions. Check for identical electrical characteristics such as impedance and leakage current.
