1N4153 BK

Single Diodes Overview

The Central Semiconductor Corp 1N4153 BK is a silicon switching diode housed in the DO-35 axial leaded package. It features a maximum repetitive peak reverse voltage of 75 V and a continuous forward current rating of 150 mA. The device operates within a temperature range of -65°C to +200°C junction temperature. Key electrical characteristics include a maximum DC reverse leakage current of 20 µA at rated voltage and a forward voltage drop of 1.0 V at 150 mA. This component is designed for general-purpose rectification and signal switching applications requiring low power dissipation.

Single Diodes Feature Summary

• High operating junction temperature capability up to 200°C
• Low forward voltage drop for efficient signal rectification
• Robust construction in standard DO-35 axial leaded package

Single Diodes Applications

• General-purpose rectification in low-power circuits
• Signal switching and clamping applications
• Reverse polarity protection for sensitive components

Single Diodes Procurement Notes

Verify current availability status as this part may be obsolete or subject to specific manufacturer ordering requirements. Confirm RoHS compliance details and exact datasheet revisions with the supplier before finalizing procurement plans. Ensure substitute parts meet all electrical specifications if original stock is unavailable.

Single Diodes Selection Notes

Select this component for applications requiring a 75V reverse voltage rating and 150mA forward current capacity. The DO-35 package suits through-hole PCB designs. Consider the high junction temperature limit for environments with significant thermal stress. Verify that the 1.0V forward voltage drop aligns with circuit efficiency requirements.

Single Diodes Part Context

The 1N4153 BK belongs to the standard silicon switching diode family from Central Semiconductor. It shares the DO-35 form factor common to many small-signal diodes but offers specific voltage and current ratings tailored for general-purpose use. The 'BK' suffix typically denotes bulk packaging, distinguishing it from tape-and-reel variants.

Single Diodes Replacement Considerations

Public confirmed substitutes include Vishay General Semiconductor's 1N4151TR. Verify that any replacement matches the 75V reverse voltage and 150mA current ratings. Ensure the alternative device supports the required 200°C junction temperature and DO-35 package compatibility.
