1N1662

Single Diodes Overview

The Microchip Technology 1N1662 is a standard recovery silicon rectifier diode designed for high-current power applications. It features a maximum DC reverse voltage (Vr) rating of 150 V and supports an average rectified current (Io) capability suitable for heavy-duty circuits. The device exhibits a peak forward surge current of 5000 A under 8/20µs pulse conditions, ensuring robustness against transient overloads. With a test leakage current of 75 µA, it maintains low standby losses. Packaged in DO-9 or DO-205AB formats, this component serves as a reliable solution for industrial power conversion systems requiring durable standard rectification.

Single Diodes Applications

• Industrial power supply rectification
• Motor drive circuit protection
• Heavy-duty AC to DC conversion

Single Diodes Procurement Notes

Verify the specific package variant (DO-9 vs. DO-205AB) and manufacturer origin, as multiple suppliers including IR and Vishay produce equivalent parts. Confirm that the source document explicitly identifies Microchip Technology as the manufacturer for the specific lot. Ensure the datasheet confirms the 150V rating and 5000A surge current specifications before finalizing procurement to avoid compatibility issues in high-power designs.

Single Diodes Selection Notes

Select the 1N1662 when a standard recovery diode with high surge tolerance is required for moderate voltage applications up to 150V. Consider the physical mounting constraints of the DO-9 or DO-205AB package during PCB or chassis design. This component is appropriate for circuits where reverse recovery speed is not critical but high current handling and ruggedness are primary requirements.

Single Diodes Part Context

The 1N1662 belongs to the broader family of 1N series silicon rectifiers, widely used in industrial controls. It is functionally interchangeable with equivalents from other manufacturers such as International Rectifier (IR), Vishay, and GE. The part is often referenced in replacement lists for legacy industrial equipment, maintaining relevance due to its standardized electrical ratings and mechanical form factors.

Single Diodes Replacement Considerations

Equivalent parts include 1N1662 produced by IR, Vishay, and Ruttonsha. Verify pinout and thermal resistance compatibility when substituting with aftermarket versions. Ensure the replacement meets the same 150V reverse voltage and 5000A surge current specifications.
