GPAS1003 MNG Equivalent & Substitute Parts

Part Overview

The GPAS1003 MNG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 V DC reverse voltage and 10 A average rectified current. The device is housed in a TO-263AB (D2PAK) surface mount package and is classified as Active product status with ROHS3 compliance. This diode is suitable for standard recovery applications in power supply and rectification circuits.

Substitute parts are identified when equivalent electrical performance can be achieved within the same package family while maintaining or exceeding the primary voltage and current specifications. Alternative models may be required due to inventory availability, thermal performance requirements, or application-specific current demands.

Substitute Part Grouping Explanation

Substitute parts for the GPAS1003 MNG are qualified based on the following criteria:

Mandatory Compatibility Parameters:

Voltage - DC Reverse (Vr) (Max): Equal to or greater than 200 V
Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant
Product Status: Active

Current Rating Consideration: Substitute diodes may have current ratings equal to, greater than, or lower than the primary 10 A specification. Higher current ratings provide design margin and thermal headroom. Lower current ratings are not suitable for direct substitution in applications requiring the full 10 A specification.

Recovery Speed Classification: The GPAS1003 MNG operates as a Standard Recovery diode (>500 ns). Substitute parts classified as Fast Recovery (≤500 ns) are electrically compatible and provide improved switching characteristics.

Thermal Performance: Operating temperature range differences between the main part (-55°C to 150°C) and substitute parts (maximum 175°C) do not restrict substitution in standard applications.

Engineering Selection Recommendations

STTH802G-TR Substitution: The STTH802G-TR is suitable for applications where the current requirement does not exceed 8 A. This part provides Fast Recovery characteristics with a 30 ns reverse recovery time, improving switching performance compared to the GPAS1003 MNG. The lower current rating restricts use to designs with maximum load currents at or below 8 A. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are equivalent.

STTH2002G-TR Substitution: The STTH2002G-TR is suitable for applications requiring up to 20 A average rectified current. This part maintains the 200 V reverse voltage rating and provides Fast Recovery operation with a 40 ns reverse recovery time. The higher current capacity provides design margin for applications operating near the 10 A specification of the GPAS1003 MNG. All compliance certifications are equivalent.

STTH3002G-TR Substitution: The STTH3002G-TR is suitable for applications requiring up to 30 A average rectified current. This part maintains the 200 V reverse voltage rating and provides Fast Recovery operation with a 50 ns reverse recovery time. The significantly higher current capacity provides substantial thermal and electrical margin. All compliance certifications are equivalent.

General Substitution Criteria: All substitute parts maintain identical 200 V reverse voltage ratings, TO-263-3 D2PAK package compatibility, surface mount configuration, and ROHS3 compliance status. Selection between substitute options depends on application current requirements and thermal design considerations. Parts with current ratings below 10 A are not suitable for direct replacement in applications requiring the full 10 A specification.

Frequently Asked Questions (FAQ)

Q: Can STTH802G-TR replace GPAS1003 MNG in all applications?

A: No. The STTH802G-TR has a maximum average rectified current rating of 8 A, which is lower than the GPAS1003 MNG specification of 10 A. This part is suitable only for applications with maximum current requirements at or below 8 A.

Q: What is the primary advantage of using STTH2002G-TR or STTH3002G-TR over GPAS1003 MNG?

A: Both parts provide higher current ratings (20 A and 30 A respectively) while maintaining the same 200 V reverse voltage specification and D2PAK package. These parts also feature Fast Recovery operation (≤500 ns) compared to the Standard Recovery (>500 ns) of the GPAS1003 MNG, resulting in reduced switching losses and improved thermal performance in high-frequency applications.

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

A: Yes. All substitute parts use the TO-263-3 D2PAK (2 Leads + Tab) package, which is mechanically and electrically compatible with the GPAS1003 MNG. Direct board-level substitution is possible without PCB redesign.

Q: Do substitute parts have different compliance certifications?

A: No. All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification, identical to the GPAS1003 MNG.

Q: What is the difference between Standard Recovery and Fast Recovery diodes?

A: Standard Recovery diodes have reverse recovery times greater than 500 ns, while Fast Recovery diodes have reverse recovery times of 500 ns or less. Fast Recovery diodes exhibit lower switching losses and reduced electromagnetic interference, making them suitable for higher-frequency switching applications.

Q: Can STTH3002G-TR be used in place of GPAS1003 MNG without circuit modifications?

A: Yes. The STTH3002G-TR maintains the same 200 V reverse voltage rating, forward voltage characteristics, and D2PAK package configuration. The higher current rating (30 A versus 10 A) provides additional thermal margin and does not require circuit modifications for direct substitution.

Q: How do reverse leakage current differences affect substitution?

A: The GPAS1003 MNG specifies 5 µA reverse leakage at 200 V, while substitute parts range from 6 µA to 20 µA. These differences are within acceptable ranges for general-purpose rectification applications and do not restrict substitution in standard power supply designs.

Q: What packaging options are available for substitute parts?

A: STTH802G-TR is supplied in Cut Tape (CT) and Digi-Reel® packaging. STTH2002G-TR is supplied in Tape & Reel (TR) packaging. STTH3002G-TR is supplied in Cut Tape (CT) packaging. All packaging formats are compatible with standard assembly processes.
