GP1004H Equivalent & Substitute Parts Reference

Part Overview

The GP1004H is a diode array rectifier manufactured by Taiwan Semiconductor Corporation, configured as a 1 Pair Common Cathode design rated for 400 V DC reverse voltage and 10 A average rectified current per diode. The component is packaged in a TO-220-3 through-hole configuration and is qualified to AEC-Q101 automotive standards with ROHS3 compliance.

The GP1004H has been discontinued at DiGi Electronics. Equivalent and substitute parts are available to maintain design continuity and support ongoing production requirements. Substitute selection depends on matching critical electrical parameters including reverse voltage rating, current capacity, forward voltage characteristics, and recovery speed specifications.

Substitute Part Grouping Explanation

Substitute parts for the GP1004H are classified into two categories based on electrical parameter alignment:

Parametric Equivalent: Parts that match all critical electrical specifications including reverse voltage rating (400 V), current capacity (10 A), forward voltage characteristics, recovery speed, and operating temperature range. These parts are direct functional replacements with identical performance envelopes.

Similar Parts: Parts that share the same reverse voltage rating (400 V), diode configuration (1 Pair Common Cathode), and through-hole TO-220-3 packaging, but differ in one or more of the following parameters: average rectified current capacity, forward voltage drop, recovery speed characteristics, or maximum junction temperature. Similar parts are suitable for applications where the design specifications allow for higher current ratings or improved recovery performance.

The critical parameters determining substitution eligibility are:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 400 V minimum
• Mounting Type: Through Hole
• Package / Case: TO-220-3
• RoHS Status: ROHS3 Compliant

Parameter Comparison

Engineering Selection Recommendations

GP1004 (Parametric Equivalent): This part is the direct equivalent to the GP1004H, matching all electrical specifications including 10 A current capacity, 1.1 V forward voltage at 5 A, and standard recovery speed characteristics. The GP1004 is currently active in inventory with 2057 pieces available. This part is the primary replacement for discontinued GP1004H applications. Automotive grade and AEC-Q101 qualification status are not specified for this part; applications requiring automotive certification should confirm compliance requirements with the manufacturer.

VS-16CTU04HN3 (Similar - Lower Current Rating): This Vishay part is suitable for applications where the design current requirement is 8 A or lower. The VS-16CTU04HN3 offers improved recovery performance (24 ns trr) and extended maximum junction temperature (175 °C) compared to the GP1004H. This part maintains automotive grade and AEC-Q101 qualification. The forward voltage is higher at 1.3 V @ 8 A and reverse leakage is higher at 10 µA @ 400 V. Use this part only when the application current requirement does not exceed 8 A per diode.

FEP16GT-E3/45 (Similar - Higher Current Rating): This Vishay part is suitable for applications requiring higher current capacity at 16 A per diode. The FEP16GT-E3/45 offers fast recovery performance (50 ns trr) and is available in high inventory (4774 pieces). The forward voltage is higher at 1.3 V @ 8 A and reverse leakage is higher at 10 µA @ 400 V. Automotive grade and AEC-Q101 qualification status are not specified for this part. Use this part when the application design allows for higher current ratings and improved recovery characteristics.

All substitute parts maintain ROHS3 compliance and TO-220-3 through-hole packaging compatibility with the original GP1004H design.

Frequently Asked Questions (FAQ)

Q: Can the GP1004 be used as a direct replacement for the GP1004H?

A: Yes. The GP1004 is a parametric equivalent with identical electrical specifications: 400 V reverse voltage, 10 A average rectified current per diode, 1.1 V forward voltage at 5 A, and standard recovery speed characteristics. Both parts use TO-220-3 through-hole packaging and are ROHS3 compliant. The GP1004 is currently active with higher inventory availability.

Q: What is the difference between the GP1004H and the VS-16CTU04HN3?

A: The VS-16CTU04HN3 has a lower average rectified current rating of 8 A compared to the GP1004H at 10 A. The VS-16CTU04HN3 offers improved recovery performance (24 ns trr versus unspecified for GP1004H) and extended maximum junction temperature (175 °C versus 150 °C). Both parts share the same 400 V reverse voltage rating and TO-220-3 packaging. The VS-16CTU04HN3 is suitable only for applications where the design current does not exceed 8 A per diode.

Q: Can the FEP16GT-E3/45 replace the GP1004H in all applications?

A: The FEP16GT-E3/45 is mechanically and electrically compatible in terms of reverse voltage (400 V) and packaging (TO-220-3). However, the FEP16GT-E3/45 has a higher average rectified current rating of 16 A and higher forward voltage drop (1.3 V @ 8 A versus 1.1 V @ 5 A). The FEP16GT-E3/45 is suitable for applications where the design specifications allow for higher current capacity and improved recovery performance. Applications requiring exact current matching at 10 A should use the GP1004 parametric equivalent.

Q: Are all substitute parts automotive qualified?

A: The GP1004H and VS-16CTU04HN3 are both automotive grade with AEC-Q101 qualification. The GP1004 and FEP16GT-E3/45 do not have specified automotive grade or AEC-Q101 qualification in the provided data. Applications requiring automotive certification should confirm compliance requirements with the respective manufacturers before selection.

Q: What is the difference between standard recovery and fast recovery diodes?

A: The GP1004H uses standard recovery characteristics (>500 ns). The VS-16CTU04HN3 and FEP16GT-E3/45 use fast recovery characteristics (≤500 ns). Fast recovery diodes have shorter reverse recovery times (24 ns and 50 ns respectively), which reduces switching losses and improves efficiency in high-frequency applications. Standard recovery diodes are suitable for lower-frequency rectification applications.

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

A: Yes. All substitute parts use TO-220-3 through-hole packaging, which is mechanically and electrically compatible with the GP1004H. The GP1004 is supplied in tube packaging, while the VS-16CTU04HN3 and FEP16GT-E3/45 are also supplied in tube packaging. All parts are suitable for through-hole PCB assembly.

Q: What is the reverse leakage current difference between the parts?

A: The GP1004H has reverse leakage of 5 µA @ 400 V. The GP1004 has lower reverse leakage at 2 µA @ 400 V. The VS-16CTU04HN3 and FEP16GT-E3/45 both have higher reverse leakage at 10 µA @ 400 V. Lower reverse leakage is beneficial for low-power standby applications and reduces heat generation at rated voltage.
