Substitute Part Grouping Explanation

Substitution of the SR20150H is determined by the following critical parameters: diode configuration (1 Pair Common Cathode), technology (Schottky), reverse voltage rating (150 V), average rectified current per diode (20 A), package type (TO-220-3), and mounting method (Through Hole). Parts are grouped into two categories:

Parametric Equivalent: SR20150 C0G maintains identical electrical specifications and package configuration, differing only in product status (Active versus Discontinued).

Similar Parts with Current Derating: Substitute parts from Vishay General Semiconductor and Diodes Incorporated provide the same 150 V reverse voltage and TO-220-3 package but with reduced current ratings (5 A, 10 A, or 15 A per diode). These parts are suitable for applications where the full 20 A current capability is not required. The V40M150C-M3/4W provides a 20 A rated alternative with extended temperature range and automotive qualification.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent): SR20150 C0G is the direct parametric equivalent to SR20150H. Both parts share identical electrical specifications, current rating, voltage rating, and package configuration. SR20150 C0G is currently Active in product status, making it the primary choice for direct substitution in applications requiring the full 20 A per diode capability.

Automotive-Qualified Alternative: V40M150C-M3/4W is recommended for applications requiring automotive qualification and extended operating temperature range. This part maintains the 20 A current rating and 150 V reverse voltage of the SR20150H while providing AEC-Q101 qualification and operating temperature range of -40°C to 175°C. Forward voltage is 1.43 V @ 20 A, compared to 1 V @ 10 A for the SR20150H.

Current-Derated Alternatives: V30150C-E3/4W (15 A), V20150C-E3/4W (10 A), V10150C-E3/4W (5 A), and MBR10150CT-G1 (5 A) are suitable for applications where the full 20 A current capability is not required. All maintain the 150 V reverse voltage rating and TO-220-3 package. These parts are Active in product status and provide design flexibility for lower-current applications.

Frequently Asked Questions (FAQ)

Q: Can SR20150 C0G be used as a direct replacement for SR20150H? A: Yes. SR20150 C0G is a parametric equivalent with identical electrical specifications, current rating (20 A per diode), voltage rating (150 V), and TO-220-3 package configuration. The primary difference is product status: SR20150 C0G is Active while SR20150H is Discontinued.

Q: What is the difference between the SR20150H and V40M150C-M3/4W? A: Both parts provide 20 A per diode at 150 V reverse voltage in TO-220-3 package. V40M150C-M3/4W offers extended operating temperature range (-40°C to 175°C versus -55°C to 150°C) and carries AEC-Q101 automotive qualification. Forward voltage differs: 1.43 V @ 20 A for V40M150C-M3/4W versus 1 V @ 10 A for SR20150H.

Q: Can I use a 15 A rated part (V30150C-E3/4W) in place of the 20 A rated SR20150H? A: Substitution is valid only if the application circuit does not require the full 20 A per diode capability. The V30150C-E3/4W maintains the same 150 V reverse voltage rating and TO-220-3 package. Circuit design must be verified to confirm that peak and average current demands do not exceed 15 A per diode.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All parts listed in this reference are ROHS3 Compliant and REACH Unaffected, meeting current environmental compliance requirements.

Q: What is the significance of the TO-220-3 package designation? A: TO-220-3 indicates a three-lead through-hole package in the TO-220 form factor. All parts in this reference use this identical package, ensuring mechanical and thermal compatibility in PCB layouts designed for the SR20150H.

Q: Which substitute part is recommended for new automotive designs? A: V40M150C-M3/4W is recommended for new automotive designs. It provides 20 A per diode at 150 V, AEC-Q101 qualification, extended temperature range, and is currently Active in product status.
