Taiwan Semiconductor Corporation GP1002H

Overview

GP1002H from Taiwan Semiconductor is an AEC-Q101-qualified 10A, 100V standard rectifier diode in TO-220AB package with dual-die configuration, 125A surge rating, and 1.1V max forward voltage at 5A/25°C - used in automotive DC-DC converters and industrial switching inverters.

For engineers reviewing the GP1002H datasheet, GP1002H pinout, GP1002H application, or GP1002H equivalent, key selection criteria include repetitive peak reverse voltage (100 V), junction-to-case thermal resistance (3 °C/W), AEC-Q101 qualification status, RoHS/halogen-free compliance, and TO-220AB mechanical mounting requirements.

Technical Context

The GP1002H integrates two independent rectifier dies in a single TO-220AB package, enabling dual-channel operation without external paralleling. Its 100 V V_RRM and 125 A I_FSM support high-reliability transient handling in 12 V–48 V automotive power rails.

Thermal performance is defined by R_θJC = 3 °C/W and T_J range of –55 °C to +150 °C, allowing direct heatsink mounting with ≤0.56 N·m torque. Reverse leakage remains ≤5 µA at 25 °C and ≤200 µA at 125 °C under rated VR.

FAQ

What is the peak repetitive reverse voltage rating for GP1002H?

The GP1002H has a peak repetitive reverse voltage (V_RRM) rating of 100 V. This value is specified in the Absolute Maximum Ratings table and defines the maximum reverse-biased voltage the device can withstand repeatedly without breakdown. It is critical for selecting appropriate snubber components and verifying margin against system DC bus transients in applications like automotive DC-DC converters.

Is GP1002H qualified for automotive applications?

Yes, GP1002H is explicitly AEC-Q101 qualified, as confirmed by the "H" suffix in its ordering code and documented in the Features section. This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling - validating its suitability for under-hood automotive power electronics such as engine control units and 48 V subsystems.

What is the thermal resistance from junction to case for GP1002H?

The junction-to-case thermal resistance (R_θJC) of GP1002H is 3 °C/W, measured under standard test conditions. This parameter enables accurate junction temperature calculation when the device is mounted to a heatsink with known thermal interface resistance. It directly impacts maximum allowable power dissipation at a given case temperature and is essential for thermal design in high-current applications like server PSUs.

Does GP1002H have a common cathode configuration?

Yes, GP1002H uses a common-cathode dual-die configuration in TO-220AB package, with two anodes and one shared cathode terminal. This structure is confirmed in the Mechanical Data and Key Parameters sections. It allows independent AC inputs while delivering rectified output through a single low-inductance cathode path - beneficial for interleaved or dual-phase rectifier designs.

What is the maximum forward voltage drop of GP1002H at rated current?

The GP1002H has a maximum forward voltage (V_F) of 1.1 V at 5 A and 25 °C junction temperature, per the Electrical Specifications table. This value reflects worst-case conduction loss under pulsed test conditions (PW = 0.3 ms). At full 10 A continuous current and elevated temperature, actual V_F will be higher, requiring thermal derating per the Forward Current Derating Curve in the datasheet.
