2N6182

Overview

The 2N6182 is a silicon planar transient voltage suppression (TVS) diode manufactured by Microchip Technology. It is designed for bidirectional protection against high-energy transients in electronic circuits. The device utilizes an axial leaded package configuration suitable for through-hole mounting. Key electrical characteristics include a working voltage of 170 V and a breakdown voltage of 190 V. It withstands a peak pulse current of 510 mA with a corresponding peak pulse power dissipation of 1.5 kW. The component exhibits a low capacitance of 4 pF, making it suitable for high-speed signal lines. It operates within a temperature range from -55°C to +175°C.

Feature Summary

• Bidirectional transient voltage suppression capability for symmetric circuit protection
• Low junction capacitance design to minimize signal distortion on high-speed lines
• High peak pulse power dissipation rating for robust transient energy handling
• Extended operating temperature range supporting harsh environmental conditions

Applications

• Protection of high-speed data communication interfaces
• Surge protection for sensitive electronic input/output ports
• Transient suppression in industrial control systems
• Electrostatic discharge (ESD) protection for signal lines

Procurement Notes

Verify the specific datasheet revision and compliance documentation directly with Microchip Technology or authorized distributors before procurement. Confirm that the axial leaded package variant matches the target PCB footprint requirements. Ensure that the bidirectional polarity specification aligns with the circuit design needs, as unidirectional alternatives may exist within the same product family. Validate thermal management capabilities under expected peak pulse conditions.

Selection Notes

Select this component when bidirectional protection is required for signals with a nominal voltage near 170 V. The low capacitance value makes it appropriate for applications where signal integrity is critical. Consider the 1.5 kW peak pulse power rating to ensure adequate margin against anticipated surge events. Verify that the axial package style fits the assembly constraints compared to surface-mount options available in the broader TVS diode portfolio.

Part Context

The 2N6182 belongs to Microchip Technology's discrete semiconductor lineup, specifically within the transient voltage suppression diode category. This part number represents a standard military-style designation often associated with ruggedized or legacy form-factor components. It complements other TVS devices offered by the manufacturer that provide similar protection functions but may differ in package type, such as MELF or SMD variants, or in electrical specifications like unidirectional configurations.

Replacement Considerations

Direct replacements must match the bidirectional polarity, 170 V working voltage, and axial package style. Equivalent parts from other manufacturers should be verified for identical pinout, peak pulse power ratings, and capacitance values to ensure circuit compatibility without redesign.
