MBRD330RL Equivalent & Substitute Parts

Part Overview

The MBRD330RL is a Schottky rectifier diode manufactured by onsemi, rated for 30 V DC reverse voltage and 3 A average rectified current in a Surface Mount DPAK package. This component is classified as Obsolete, indicating it has reached end-of-life status and is no longer in active production. The identification of equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRD330RL is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 30 V minimum
• Current - Average Rectified (Io): 3 A minimum
• Technology: Schottky
• Mounting Type: Surface Mount
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63

Substitution Categories:

Direct Equivalent: Parts that match all primary criteria with identical electrical performance specifications. These parts are pin-compatible and functionally interchangeable without circuit modification.

Functional Equivalent with Enhanced Ratings: Parts that exceed the minimum current rating while maintaining identical voltage ratings and package form factor. These parts are suitable for applications where the original specification is met or exceeded.

Cross-Manufacturer Equivalent: Parts from alternative manufacturers that satisfy all primary substitution criteria and maintain electrical performance within specified tolerances.

Parameter Comparison

Engineering Selection Recommendations

MBRD330RLG (onsemi): This part is the direct onsemi equivalent to the MBRD330RL, maintaining identical electrical specifications and package configuration. The MBRD330RLG is classified as Last Time Buy, indicating limited availability. This part achieves ROHS3 compliance, addressing environmental regulatory requirements that the original MBRD330RL does not meet. Selection of this part is appropriate for applications requiring onsemi component continuity and RoHS compliance.

VS-MBRD330TR-M3 (Vishay General Semiconductor - Diodes Division): This part provides direct functional equivalence to the MBRD330RL across all primary electrical parameters: 30 V reverse voltage, 3 A average rectified current, and identical forward voltage characteristics. The VS-MBRD330TR-M3 is classified as Active, ensuring ongoing availability and supply chain stability. This part is ROHS3 compliant and carries AEC-Q101 automotive qualification. The operating temperature range is -40°C to 150°C, which is narrower than the original part's -65°C to 150°C range. Selection of this part is appropriate for applications where cross-manufacturer substitution is acceptable and where the narrower low-temperature operating range does not present a constraint.

VS-50WQ03FNTRRHM3 (Vishay General Semiconductor - Diodes Division): This part provides functional equivalence with enhanced current rating of 5.5 A, exceeding the original 3 A specification while maintaining the 30 V reverse voltage rating and identical package form factor. The VS-50WQ03FNTRRHM3 is classified as Active with ROHS3 compliance and AEC-Q101 automotive qualification. Forward voltage is reduced to 460 mV at 5 A, indicating improved efficiency characteristics. Reverse leakage current is elevated to 3 mA at 30 V compared to the original 200 µA specification. The operating temperature range is -40°C to 150°C. Selection of this part is appropriate for applications where the enhanced current rating provides design margin and where the increased reverse leakage current does not present a constraint.

Frequently Asked Questions (FAQ)

Q: Can the MBRD330RLG be used as a direct replacement for the MBRD330RL?

A: Yes. The MBRD330RLG maintains identical electrical specifications including 30 V reverse voltage, 3 A average rectified current, 600 mV forward voltage at 3 A, and fast recovery characteristics. Both parts use the TO-252-3 DPAK package. The primary difference is product status and RoHS compliance; the MBRD330RLG is Last Time Buy and ROHS3 compliant, while the MBRD330RL is Obsolete and RoHS non-compliant.

Q: What are the differences between the onsemi MBRD330RLG and the Vishay VS-MBRD330TR-M3?

A: Both parts are electrically equivalent with 30 V reverse voltage, 3 A average rectified current, and 600 mV forward voltage at 3 A. Both use the TO-252-3 DPAK package. The VS-MBRD330TR-M3 has a narrower operating temperature range (-40°C to 150°C versus -65°C to 150°C) and includes AEC-Q101 automotive qualification. Both are ROHS3 compliant and Active status.

Q: Can the VS-50WQ03FNTRRHM3 replace the MBRD330RL in all applications?

A: The VS-50WQ03FNTRRHM3 meets the minimum voltage and current requirements with enhanced 5.5 A rating. However, the reverse leakage current is 3 mA at 30 V compared to the original 200 µA specification. This elevated leakage may affect applications sensitive to standby current or leakage-dependent performance. The operating temperature range is also narrower at -40°C to 150°C. Verification of leakage current tolerance and temperature range requirements is necessary before selection.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts use the TO-252-3 DPAK (2 Leads + Tab), SC-63 package configuration, ensuring mechanical and electrical compatibility with the original MBRD330RL footprint.

Q: What is the significance of RoHS compliance for these parts?

A: The MBRD330RL is RoHS non-compliant, while all substitute parts (MBRD330RLG, VS-MBRD330TR-M3, and VS-50WQ03FNTRRHM3) are ROHS3 compliant. RoHS3 compliance indicates the parts do not contain restricted substances including lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, or polybrominated diphenyl ethers. Selection of RoHS-compliant parts is required for applications subject to environmental regulations in the European Union and other jurisdictions with equivalent requirements.

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

A: For new designs requiring direct electrical equivalence with active product status and RoHS compliance, the VS-MBRD330TR-M3 is appropriate. For applications where enhanced current rating provides design margin, the VS-50WQ03FNTRRHM3 is suitable provided reverse leakage current and operating temperature range constraints are satisfied. For onsemi-specific supply chains, the MBRD330RLG is available as Last Time Buy with limited inventory.

Q: What is the difference between Last Time Buy and Obsolete product status?

A: Last Time Buy status indicates the manufacturer is accepting final orders before discontinuation, with a defined cutoff date. Obsolete status indicates the product has already been discontinued and is no longer available from the manufacturer. The MBRD330RLG is Last Time Buy with finite inventory, while the MBRD330RL is Obsolete with no new production available.
