DBA150G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBA150G is a single-phase bridge rectifier manufactured by onsemi, rated for 600 V peak reverse voltage with 4.5 A average rectified current. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The through-hole mounting configuration and standard rectification technology establish the baseline for equivalent part selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DBA150G is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Peak Reverse (Max): 600 V minimum
• Current - Average Rectified (Io): Equal to or greater than 4.5 A
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Package Configuration: Compatible 4-pin through-hole form factor

The GBU6J-M3/51 qualifies as a direct substitute based on matching peak reverse voltage (600 V), exceeding the current rating (6 A vs. 4.5 A), maintaining single-phase bridge rectifier topology, and providing through-hole mounting in a compatible 4-SIP package footprint.

Parameter Comparison

Engineering Selection Recommendations

The GBU6J-M3/51 is suitable for direct substitution of the DBA150G in applications requiring a 600 V, single-phase bridge rectifier with through-hole mounting. The substitute part meets or exceeds all critical electrical parameters: peak reverse voltage equivalence, current rating surplus (6 A vs. 4.5 A), and improved reverse leakage characteristics (5 µA vs. 10 µA).

The GBU6J-M3/51 is currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete DBA150G. Both parts maintain identical compliance classifications (REACH Unaffected, EAR99, HTSUS 8541.10.0080) and moisture sensitivity levels (MSL 1 - Unlimited).

Package footprint compatibility between the 4-Square GBPC-W and 4-SIP GBU configurations supports direct board-level substitution without circuit redesign. The extended operating temperature range of the GBU6J-M3/51 (-55°C ~ 150°C) provides additional thermal margin compared to the DBA150G specification (150°C maximum).

Frequently Asked Questions (FAQ)

Q: Can the GBU6J-M3/51 replace the DBA150G in existing designs?

A: Yes. The GBU6J-M3/51 meets all electrical requirements for direct substitution: 600 V peak reverse voltage, current rating exceeding 4.5 A, and compatible through-hole mounting. Package footprints are mechanically compatible for board-level replacement.

Q: What are the key differences between these parts?

A: The GBU6J-M3/51 provides higher current capacity (6 A vs. 4.5 A), lower reverse leakage (5 µA vs. 10 µA), and an extended operating temperature range (-55°C ~ 150°C vs. 150°C maximum). The substitute is in active production, whereas the DBA150G is obsolete.

Q: Are there compliance or certification differences?

A: Both parts share identical compliance status: REACH Unaffected, EAR99 export classification, and HTSUS code 8541.10.0080. Moisture sensitivity levels are equivalent (MSL 1 - Unlimited).

Q: Does the package change affect circuit board layout?

A: The 4-Square GBPC-W and 4-SIP GBU packages maintain compatible through-hole pin configurations and spacing, supporting direct footprint substitution without PCB redesign.

Q: Why is the DBA150G classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by onsemi. The GBU6J-M3/51 represents an active-production alternative with equivalent or superior electrical characteristics.
