Key Parameters

Substitute Part Grouping Explanation

Equivalent and substitute models are determined by strict matching or full inclusion of the following key electrical and mechanical parameters: diode configuration (1 pair common cathode), technology (Schottky), maximum reverse voltage (20 V), mounting type (Chassis Mount), package/case (Three Tower), speed specification (Fast Recovery =< 500ns, >200mA), operating temperature range, and moisture sensitivity level (MSL 1, unlimited). Current handling and forward voltage are noted in comparison but must be evaluated as part of the specification match. Only parts with all matching parameters as described above are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

MBRT40020L is classified as obsolete. MBRT20020 is active and shares all mechanical and technology parameters, including chassis mount, three-tower package, and Schottky construction, as well as full environmental and compliance equivalence (RoHS Status and MSL 1 unlimited). Selection should align with project requirements for active status and compliance where needed.

Frequently Asked Questions (FAQ)

Q1: What is the main electrical difference between MBRT40020L and MBRT20020?
A1: The main difference is the average rectified current rating per diode: MBRT40020L is 200A while MBRT20020 is 100A. Other critical electrical and mechanical parameters are matched.

Q2: Is the package and mounting type identical between MBRT40020L and MBRT20020?
A2: Yes, both use the Three Tower package and are chassis mount.

Q3: What configuration do both diodes use?
A3: Both are configured as 1 pair common cathode.

Q4: Are there differences in reverse leakage or forward voltage?
A4: MBRT40020L has a reverse leakage of 3 mA @ 20 V and a forward voltage of 580 mV @ 200 A; MBRT20020 has 1 mA @ 20 V and 750 mV @ 100 A.

Q5: What are the implications of the product status?
A5: MBRT40020L is obsolete, meaning it is not available from standard manufacturing channels. MBRT20020 is active and available in inventory.

Q6: Are compliance and moisture sensitivity levels matched?
A6: Both MBRT40020L and MBRT20020 have MSL 1 (Unlimited), and MBRT20020 has explicit RoHS compliance as listed.

Q7: What criteria must be met for substitution in this diode category?
A7: Substitution requires identical diode configuration, reverse voltage, technology, packaging, mounting type, and environmental tolerance. Current handling capability must be reviewed per application requirements.
