1N2286 Equivalent & Substitute Parts

Part Overview

The 1N2286 is a general-purpose rectifier diode manufactured by Microchip Technology, rated for 800 V DC reverse voltage and 20 A average rectified current in a stud-mount DO-203AB (DO-5) package. This component is classified as Active product status and utilizes standard recovery technology with a reverse recovery time of 5 µs. The diode operates across a junction temperature range of -65°C to 200°C and is suitable for high-voltage rectification applications requiring stud mounting. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when application requirements permit higher current ratings within the same voltage and package specifications.

Substitute Part Grouping Explanation

Substitution of the 1N2286 with the VS-42HF80 is permissible based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

Voltage - DC Reverse (Vr) (Max): Both rated at 800 V
Package / Case: Both utilize DO-203AB (DO-5) stud mount configuration
Mounting Type: Both feature stud mount capability
Technology: Both employ standard recovery technology with >500 ns recovery speed
Current - Reverse Leakage @ Vr: Both specified at 10 µA @ 800 V
Operating Temperature Range: Both support -65°C minimum; 1N2286 extends to 200°C, VS-42HF80 to 190°C
Product Status: Both classified as Active

Differing Parameters:

Current - Average Rectified (Io): 1N2286 rated at 20 A; VS-42HF80 rated at 40 A
Voltage - Forward (Vf) (Max): 1N2286 at 1.19 V @ 90 A; VS-42HF80 at 1.3 V @ 125 A

The VS-42HF80 provides higher current capacity within identical voltage and package constraints, permitting its use in applications where the 1N2286 is specified, provided the application circuit does not require the lower forward voltage characteristic of the original part.

Engineering Selection Recommendations

Both the 1N2286 and VS-42HF80 maintain Active product status, ensuring continued availability and manufacturer support. The 1N2286 is manufactured by Microchip Technology, while the VS-42HF80 is supplied by Vishay General Semiconductor - Diodes Division. Both components are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8541.10.0080.

The VS-42HF80 is RoHS3 Compliant with Moisture Sensitivity Level (MSL) 1 (Unlimited), providing enhanced environmental compliance. The 1N2286 does not specify RoHS status in the provided data.

Selection between these parts depends on application current requirements. The 1N2286 is appropriate for circuits requiring exactly 20 A average rectified current. The VS-42HF80 accommodates applications requiring up to 40 A, offering design margin and potential thermal performance benefits through lower current density. Both parts share identical 800 V reverse voltage rating and DO-203AB stud-mount package, ensuring mechanical and electrical compatibility within the specified voltage class.

Frequently Asked Questions (FAQ)

Q: Can the VS-42HF80 directly replace the 1N2286 in all applications?

A: The VS-42HF80 is electrically and mechanically compatible with the 1N2286 for applications operating at or below 20 A average rectified current. The higher current rating of the VS-42HF80 (40 A) does not prevent its use in lower-current circuits. However, the forward voltage characteristic differs (1.3 V versus 1.19 V at rated conditions), which may affect circuit performance in precision applications sensitive to voltage drop.

Q: What is the significance of the DO-203AB (DO-5) stud-mount package?

A: The DO-203AB package is a stud-mount configuration designed for high-current applications requiring direct thermal coupling to a chassis or heatsink. Both the 1N2286 and VS-42HF80 utilize this package, ensuring identical mechanical mounting and thermal interface characteristics.

Q: Are there differences in operating temperature ranges between these parts?

A: The 1N2286 operates from -65°C to 200°C junction temperature, while the VS-42HF80 operates from -65°C to 190°C. For applications requiring operation above 190°C, the 1N2286 is the appropriate selection. For standard industrial applications, both parts are suitable.

Q: What compliance certifications apply to these diodes?

A: Both parts are REACH Unaffected and classified as EAR99 for export control purposes. The VS-42HF80 carries RoHS3 Compliance certification with MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The 1N2286 does not specify RoHS status in available documentation.

Q: How do reverse recovery time specifications affect substitution?

A: The 1N2286 specifies a reverse recovery time of 5 µs. The VS-42HF80 does not provide this specification in the available data. For applications where reverse recovery time is a critical design parameter, verification against the complete VS-42HF80 datasheet is necessary to confirm compatibility.
