1N4002G-K

Single Diodes Overview

The 1N4002G-K is a general-purpose silicon rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a maximum average forward rectified current of 1 A and a maximum repetitive peak reverse voltage of 100 V. The device utilizes a glass-passivated junction for high reliability and low leakage current. It is housed in the DO-41 (DO-204AL) axial leaded plastic package, designed for through-hole mounting. Key electrical characteristics include a maximum DC reverse current of 5 µA at rated voltage and a typical junction capacitance of 15 pF.

Single Diodes Feature Summary

• Glass-passivated junction structure ensures high reliability and stability under varying environmental conditions.
• High surge current capability allows the component to withstand transient overloads during operation.
• Low forward voltage drop contributes to improved efficiency in power conversion applications.

Single Diodes Applications

• General-purpose rectification in AC to DC power supply circuits
• Free-wheeling diodes in inductive load protection circuits
• Polarity protection in electronic equipment input stages

Single Diodes Procurement Notes

Verify that the specific suffix 'K' corresponds to the intended packaging or marking configuration required for your assembly process. Confirm RoHS compliance status and lead-free specifications with the manufacturer or authorized distributor prior to ordering, as these attributes may vary based on production batches and regional regulatory requirements.

Single Diodes Selection Notes

Select this component when a standard 1 A rectifier with a 100 V blocking voltage is required for through-hole PCB designs. Ensure the operating temperature range of -65°C to +175°C aligns with the thermal environment of the target application. Consider the DO-41 package dimensions for adequate spacing and mechanical clearance within the final enclosure design.

Single Diodes Part Context

This part belongs to the widely adopted 1N400x series of silicon rectifiers, which are industry-standard components for low-frequency power rectification. The 'G' suffix typically denotes a glass-passivated junction variant, offering superior performance compared to non-passivated equivalents. The 'K' suffix likely indicates a specific tape-and-reel or bulk packaging option defined by Taiwan Semiconductor for automated assembly or manual handling needs.

Single Diodes Replacement Considerations

Direct functional substitutes include the 1N4002 from other manufacturers such as Vishay, onsemi, or Rectron, provided they share the same DO-41 package and electrical ratings. Verify pinout compatibility and thermal resistance values before substituting to ensure equivalent performance in the existing circuit layout.
