FMM-22R Equivalent & Substitute Parts Reference

Part Overview

The Sanken Electric USA Inc. FMM-22R is a diode array classified under Diodes, Rectifiers. It features a configuration of 1 Pair Common Anode, a maximum DC reverse voltage of 200 V, and an average rectified current per diode of 10A. The device is supplied in a TO-220-3 Full Pack package for through-hole mounting. As the FMM-22R is marked Obsolete, identifying functionally compatible substitute rectifier diode arrays with matching electrical and mechanical parameters is necessary for continued production or maintenance.

Substitute Part Grouping Explanation

Substitute diode arrays for the FMM-22R are identified strictly by matching the following key parameters: diode configuration, maximum reverse voltage (Vr), average rectified current per diode (Io), forward voltage (Vf) at the specified forward current (If), recovery speed category, reverse leakage current, junction operating temperature, mounting type, package form factor, and compliance status. Only parts with 1 Pair Common Anode configuration, 200 V max reverse voltage, and mechanical compatibility (through-hole, TO-220-3 Full Pack variants) are included.

Engineering Selection Recommendations

Selection between the FMM-22R and SDURF3020CTR should be based on product availability and compliance certifications such as RoHS status and Moisture Sensitivity Level. The FMM-22R is obsolete, while SDURF3020CTR is active with ROHS3 compliance and matches the MSL 1 (Unlimited) classification.

Frequently Asked Questions (FAQ)

Q1: What are the main parameters to consider when selecting a substitute for FMM-22R?
A1: Diode configuration, maximum reverse voltage, average rectified current, forward voltage at specified current, reverse leakage current, junction operating temperature, mounting type, package form factor, RoHS status, and Moisture Sensitivity Level.

Q2: Is the package type of SDURF3020CTR compatible with FMM-22R?
A2: Both devices use a TO-220-3 Full Pack type package suitable for through-hole mounting.

Q3: Are there differences in RoHS compliance?
A3: FMM-22R is RoHS Compliant. SDURF3020CTR is ROHS3 Compliant.

Q4: What configuration do these diode arrays use?
A4: Both FMM-22R and SDURF3020CTR use the 1 Pair Common Anode configuration.

Q5: How does product status affect substitute selection?
A5: Since FMM-22R is obsolete, only active or in-stock substitute parts with matching parameters should be selected.
