GP1003

Diode Arrays Overview

The GP1003 is a standard recovery rectifier from the GP1001–GP1007 series by Taiwan Semiconductor. It features a dual common cathode configuration in a TO-220AB package. The device supports an average forward current of 10 A and a repetitive peak reverse voltage of 200 V. Maximum surge current capability reaches 125 A for an 8.3 ms half-sine wave. Electrical specifications include a maximum forward voltage of 1.1 V at 5 A, a typical junction-to-case thermal resistance of 3 °C/W, and a maximum junction temperature of 150 °C.

Diode Arrays Feature Summary

• Dual common cathode configuration providing two independent rectifying paths within a single component.
• High efficiency design characterized by low forward voltage drop to minimize power loss.
• Robust surge current handling capability suitable for applications with transient load demands.
• Compliant with RoHS standards and halogen-free requirements according to IEC 61249-2-21.

Diode Arrays Applications

• DC to DC converters
• Switching mode converters and inverters
• General purpose rectification

Diode Arrays Procurement Notes

Verify the specific suffix against the datasheet ordering information. The base GP1003 designation corresponds to the standard version without automotive qualification. Suffixes such as 'H' indicate AEC-Q101 qualification. Confirm the package type is TO-220AB and check packing quantities, which are typically supplied in tubes of 50 units per manufacturer specification.

Diode Arrays Selection Notes

Select this component when a 200 V blocking voltage is required alongside a 10 A continuous current rating. The dual common cathode topology allows for bridge-like configurations or center-tapped transformer applications using fewer components. Ensure the thermal management solution accounts for the 3 °C/W junction-to-case resistance to maintain operation within the 150 °C limit under expected load conditions.

Diode Arrays Part Context

This part belongs to the GP1001 through GP1007 series, which shares identical electrical characteristics except for the repetitive peak reverse voltage rating. The series covers voltage ratings from 50 V to 1000 V. All variants utilize the same TO-220AB package and support a 10 A forward current, allowing for standardized mechanical design across different voltage requirements.

Diode Arrays Replacement Considerations

Cross-reference with other 10 A, 200 V dual common cathode rectifiers in the TO-220AB package. Verify that substitute parts meet the 1.1 V forward voltage maximum and 125 A surge current requirements. Ensure the replacement maintains the same pinout configuration and thermal resistance characteristics for direct board compatibility.

Diode Arrays FAQ

What is the difference between GP1003 and GP1003H?

The GP1003H variant is AEC-Q101 qualified for automotive applications, whereas the standard GP1003 does not carry this specific automotive reliability certification.

Is the GP1003 suitable for high-frequency switching applications?

No, the GP1003 is a standard recovery rectifier. It is designed for general-purpose and lower-frequency applications rather than high-speed switching where fast recovery diodes are required.

How is the polarity marked on the device?

The polarity is indicated by the marking code on the device body, which includes the part number (GP1003), a factory code, and a date code. The cathode connection is identified by the internal die configuration common to the dual common cathode package.
