MBR7030WT Equivalent & Substitute Parts

Part Overview

The MBR7030WT is a Schottky diode array in a 1 Pair Common Cathode configuration rated for 30 V DC reverse voltage and 35 A average rectified current per diode. Manufactured by onsemi in the SWITCHMODE™ series, this component is packaged in a TO-247-3 through-hole format and is classified as obsolete. Due to its obsolete product status, equivalent substitute parts with active availability are necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the MBR7030WT is determined by the following critical parameters:

Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 30 V minimum
Current - Average Rectified (Io) (per Diode): 35 A minimum
Diode Configuration: 1 Pair Common Cathode
Technology: Schottky

Mechanical Parameters:

Mounting Type: Through Hole
Package / Case: TO-247-3

Performance Parameters:

Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Operating Temperature - Junction: -55°C minimum to 150°C minimum

Substitute parts must meet or exceed all electrical specifications and maintain identical mechanical compatibility. Forward voltage and reverse leakage characteristics may vary within acceptable engineering tolerances for the application class.

Engineering Selection Recommendations

MBR7030WTG (onsemi)

The MBR7030WTG is the direct successor to the MBR7030WT from the same manufacturer. It maintains identical electrical and thermal specifications while offering active product status and ROHS3 compliance. This part is the preferred substitute for applications requiring continuity with the original onsemi SWITCHMODE™ series design. The MBR7030WTG supports the full operating temperature range of -55°C to 175°C and is suitable for direct replacement in existing designs.

VS-72CPQ030-N3 (Vishay General Semiconductor - Diodes Division)

The VS-72CPQ030-N3 provides cross-manufacturer substitution with identical voltage and current ratings. This part meets all electrical requirements and offers improved reverse leakage characteristics (1.9 mA versus 5 mA at 30 V). The VS-72CPQ030-N3 is ROHS3 compliant and maintains the same TO-247-3 through-hole package. The operating temperature range extends to 150°C, which is 25°C lower than the original specification. This part is suitable for applications where the reduced maximum junction temperature is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the MBR7030WTG be used as a direct replacement for the MBR7030WT?

A: Yes. The MBR7030WTG is electrically and mechanically identical to the MBR7030WT. Both parts share the same voltage rating (30 V), current rating (35 A), forward voltage characteristics (550 mV @ 35 A), and operating temperature range (-55°C to 175°C). The primary difference is product status: MBR7030WTG is active while MBR7030WT is obsolete.

Q: What is the difference between the MBR7030WTG and VS-72CPQ030-N3?

A: Both parts meet the core electrical specifications of 30 V reverse voltage and 35 A current rating in a TO-247-3 package. The VS-72CPQ030-N3 has lower reverse leakage (1.9 mA versus 5 mA) and slightly lower forward voltage (510 mV versus 550 mV at 35 A). The VS-72CPQ030-N3 has a maximum junction temperature of 150°C compared to 175°C for the MBR7030WTG. Both are ROHS3 compliant.

Q: Are all substitute parts available in the same package?

A: Yes. The MBR7030WT, MBR7030WTG, and VS-72CPQ030-N3 are all packaged in TO-247-3 through-hole format. Pin configuration and mechanical dimensions are compatible for direct board-level substitution.

Q: Which substitute part should be selected for new designs?

A: Selection depends on design requirements. For onsemi component continuity, use MBR7030WTG. For applications requiring lower reverse leakage or cross-manufacturer sourcing flexibility, use VS-72CPQ030-N3. Verify that the maximum junction temperature of 150°C for the VS-72CPQ030-N3 is acceptable for your thermal environment if selecting that part.

Q: Are there compliance differences between the substitute parts?

A: Both MBR7030WTG and VS-72CPQ030-N3 are ROHS3 compliant, while the original MBR7030WT is RoHS non-compliant. Both substitute parts are REACH Unaffected. For applications requiring RoHS compliance, either substitute part is acceptable.

Q: What is the moisture sensitivity level for these parts?

A: All three parts (MBR7030WT, MBR7030WTG, and VS-72CPQ030-N3) have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
