Equivalent & Substitute Parts Reference – DSB5822

Part Overview

DSB5822 is a Schottky rectifier diode manufactured by Microchip Technology, categorized under Diodes, Rectifiers. It has a rated DC reverse voltage of 40 V, an average rectified current of 3A, and fast recovery characteristics, supplied in a through-hole DO-204AL/DO-41 axial package. Product status is "Active." In applications where DSB5822 inventory is limited or specific compliance requirements are mandated, sourcing equivalent alternative models is necessary to ensure uninterrupted production and to meet environmental, regulatory, or packaging specifications.

Substitute Part Grouping Explanation

Substitute parts for DSB5822 are chosen strictly based on identical or permitted variations in key electrical and mechanical parameters:

Schottky diode technology
DC reverse voltage rating (40 V)
Average rectified current (3A)
Fast recovery speed (≤ 500ns, > 200mA current)
Through-hole axial mounting/package compatibility

Additional selection criteria include product status (active), compliance certifications (RoHS, REACH), and inventory availability. Only components meeting or closely matching the above parameters qualify as substitutes.

Engineering Selection Recommendations

When selecting substitute parts for DSB5822, evaluate product status and environmental compliance such as RoHS and REACH certifications as provided. All listed substitute diodes are "Active" and meet REACH unaffected status. For applications requiring RoHS compliance, SB340-E3/54, SB340-E3/73, 1N5822-TP, and 1N5822RLG offer ROHS3 compliant status. Packaging and mounting compatibility (axial through-hole) are consistent across all alternatives. Base product selection strictly on availability, status, and required compliance per project or regulatory mandate.

Frequently Asked Questions (FAQ)

Q1: What determines if a diode can be substituted for DSB5822?
Substitution is determined by matching key electrical parameters: Schottky technology, DC reverse voltage (40 V), average rectified current (3A), fast recovery time, and compatible package/mounting (axial, through-hole).

Q2: Can package differences impact substitution?
Substitution requires compatible axial, through-hole packages. Ensure selected alternatives match or fit the intended mechanical layout.

Q3: How does RoHS compliance affect part selection?
If RoHS compliance is required, select substitutes with ROHS3 compliant status. DSB5822 is RoHS non-compliant; several alternatives meet ROHS3 requirements.

Q4: Are all substitutes currently active and in stock?
All substitutes listed are marked as "Active" and indicate current inventory availability as per input parameters.

Q5: Which substitute part has the closest electrical parameters to DSB5822?
SB340-E3/54 and SB340-E3/73 match the voltage, current, speed, and present the lowest forward voltage (490 mV @ 3A) of all listed, with identical mounting and package type.

Q6: Is compliance with REACH required for substitutes?
All listed alternatives indicate "REACH Unaffected" status. Select based on project or regulatory requirements.

Q7: What is the significance of operating temperature range?
Most substitutes match the original device's suitability for temperature ranges (-65°C ~ 125°C) except as noted. Verify if this matches application needs.
