1N4721 Equivalent & Substitute Diodes Reference

Part Overview

The 1N4721 from Microchip Technology is a general-purpose axial diode categorized under Diodes, Rectifiers. It features a maximum DC reverse voltage of 200 V and a maximum average rectified current of 3A. The forward voltage is 1 V at 3A with a fast recovery time suitable for rectification applications. This device is RoHS compliant, supplied in bulk packaging, and has an active product status. When production requirements, sourcing constraints, or inventory levels arise, equivalent and substitute models are essential for ensuring continuous design and manufacturing workflows.

Key Parameters

Substitute Part Grouping Explanation

Only substitute diode rectifiers that satisfy the following explicitly provided parameters are considered: device category (Diodes, Rectifiers), voltage - DC reverse (Vr) maximum of 200 V, fast recovery speed (≤ 500 ns, > 200mA), through-hole mounting, and axial package. Current rating, voltage forward characteristics, and operating temperature must match allowed application tolerances as per the data. Substitute relationships are determined exclusively by matching these parameters and product statuses. No further parameters are introduced in the equivalency comparison.

Parameter Comparison

Engineering Selection Recommendations

All substitute models listed (AU02ZV1, AU01ZV1) are in active product status with RoHS compliance, providing clear environmental and supply continuity for engineering selection based strictly on these compliance and certification fields. Inventory for all substitute and main parts is confirmed as available. No additional certifications or statuses are included in this reference.

Frequently Asked Questions (FAQ)

Q1: What are the main electrical parameters used to determine substitution compatibility for 1N4721 diodes?
A1: The main parameters are voltage - DC reverse (Vr), current - average rectified (Io), voltage forward (Vf) at specified current, speed classification, mounting type, and package/case.

Q2: Can substitute parts with lower average rectified current be used in place of 1N4721?
A2: Only substitute diodes with parameter values given in the comparison table are considered, and selection must match required application constraints; no additional assumptions are made.

Q3: Do AU02ZV1 and AU01ZV1 fit the same mechanical footprint as the 1N4721?
A3: All models are designated as Through Hole, Axial package/case, and thus are aligned in terms of package compatibility as per provided data.

Q4: How are compliance fields used in substitute selection decisions?
A4: Only product status and available REACH or RoHS compliance data are used for selection within the scope of the provided information.

Q5: Are there differences in operating temperature ranges among the listed substitutes?
A5: The main part (1N4721) specifies -65°C ~ 175°C, while substitutes specify -40°C ~ 150°C, as shown in the parameter table above.
