GBPC1504 Bridge Rectifier Single Phase 400V 15A

Part Overview

The GBPC1504 is a single-phase bridge rectifier diode rated for 400V peak reverse voltage and 15A average rectified current. Manufactured by Diodes Incorporated, this component features a standard technology platform with QC terminal mounting in a 4-square GBPC package. The original part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new procurement requirements. Alternative sources and higher-rated variants are available to maintain design continuity and ensure supply chain flexibility.

Substitute Part Grouping Explanation

Substitution of the GBPC1504 is determined by the following electrical and mechanical criteria:

Direct Electrical Equivalents — Parts maintaining identical voltage (400V) and current (15A) ratings with compatible package and mounting specifications.

Higher Current Capacity Variants — Parts with equal or higher voltage ratings (400V or greater) and current ratings exceeding 15A, suitable for applications requiring design margin or load growth accommodation.

Lower Current Variants — Parts with equal voltage rating (400V) but reduced current capacity (12A), applicable only where system load permits downrating.

Voltage-Dependent Variants — Parts with different voltage ratings (100V, 200V, 1kV) and corresponding current adjustments, selectable based on circuit voltage requirements.

Substitution validity requires matching or exceeding the original part's voltage specification and maintaining mechanical compatibility through identical or functionally equivalent package designations (GBPC or GBPC-A).

Engineering Selection Recommendations

Direct Replacement (Active Status) — GBPC1504-E4/51 from Vishay General Semiconductor and GBPC1504 from Taiwan Semiconductor Corporation are active production equivalents with identical electrical ratings. Both maintain 400V/15A specifications and ROHS3 compliance. The Vishay variant offers improved reverse leakage characteristics (5 µA vs. 10 µA). The Taiwan Semiconductor variant features chassis mount configuration instead of QC terminal.

Higher Current Capacity Substitutes — GBPC2504 (25A, 400V) and GBPC3504 (35A, 400V) provide increased current headroom while maintaining the 400V voltage specification. Both are active production parts with ROHS3 compliance. These are suitable where system design permits higher current ratings or where future load growth is anticipated.

Voltage-Specific Alternatives — GBPC2510 (25A, 1kV) and GBPC3510 (35A, 1kV) are available for applications requiring higher voltage withstand capability. GBPC2501 (25A, 100V) and GBPC3502 (35A, 200V) address lower voltage circuit requirements. Selection depends on actual circuit voltage specifications.

Avoid — GBPC1204 (onsemi, 12A, 400V) is marked "Not For New Designs" and represents a downrated variant unsuitable for new procurement unless legacy system compatibility is mandatory.

Frequently Asked Questions (FAQ)

Q: Can GBPC1504-E4/51 directly replace the original GBPC1504?

A: Yes. Both parts maintain 400V peak reverse voltage and 15A average rectified current ratings with identical forward voltage characteristics. The Vishay part is an active production equivalent with improved reverse leakage performance (5 µA vs. 10 µA at 400V). Electrical compatibility is confirmed; verify mounting configuration (QC terminal) matches your application.

Q: What is the difference between QC Terminal and Chassis Mount variants?

A: QC Terminal and Chassis Mount refer to mechanical mounting interfaces. QC Terminal uses quick-connect terminals for panel-mount applications. Chassis Mount provides direct mounting to a chassis or heatsink. Electrical performance is identical; selection depends on mechanical integration requirements.

Q: Can I use GBPC2504 (25A) in place of GBPC1504 (15A)?

A: Yes, provided your circuit voltage requirement is 400V. GBPC2504 maintains the same 400V rating with increased current capacity (25A vs. 15A). This substitution provides design margin and is suitable for applications where higher current capability is acceptable. Verify package compatibility (both use 4-square GBPC).

Q: Is GBPC3504 a suitable substitute?

A: Yes. GBPC3504 maintains 400V voltage rating with 35A current capacity, providing significant design margin. It is an active production part from Fairchild Semiconductor with ROHS3 compliance and extended temperature range (-65°C to 150°C). Use where higher current capacity is acceptable.

Q: What voltage rating should I select?

A: Select a part with voltage rating equal to or exceeding your circuit's peak reverse voltage requirement. The original GBPC1504 is rated 400V; do not substitute with lower voltage parts (100V, 200V) unless your circuit operates at those reduced voltages. Higher voltage parts (1kV) are acceptable for 400V circuits but may introduce unnecessary cost.

Q: Are all substitute parts ROHS3 compliant?

A: All active production parts listed (GBPC1504-E4/51, Taiwan Semiconductor GBPC1504, GBPC2504, GBPC3504, GBPC3510, VS-GBPC2504A) are ROHS3 compliant. GBPC1204 (onsemi) is marked "Not For New Designs" and should not be selected for new applications.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage current (10 µA for original GBPC1504 vs. 5 µA for active equivalents) indicates the small current flowing through the diode in reverse bias. Lower leakage is generally preferable for precision applications. For standard rectification, both values are acceptable; the difference is not critical for most industrial applications.
