Product details

Overview

GP1003H from Taiwan Semiconductor is an AEC-Q101-qualified 200 V, 10 A standard rectifier diode in TO-220AB package with dual-die configuration, low 1.1 V forward voltage at 5 A, and 125 A surge capability-used in automotive DC-DC converters and industrial switching inverters.

For engineers reviewing the GP1003H datasheet, GP1003H pinout, GP1003H application, or GP1003H equivalent, key selection criteria include repetitive peak reverse voltage (200 V), junction-to-case thermal resistance (3 °C/W), AEC-Q101 qualification status, and TO-220AB mechanical compatibility with heatsink mounting.

Technical Context

The GP1003H integrates two independent silicon rectifier dies in a single TO-220AB package, enabling dual-channel operation without external paralleling. Its 200 V V_RRM and 125 A I_FSM support high-reliability transient handling in 12–48 V automotive power rails.

Thermally optimized with 3 °C/W R_θJC, it sustains 10 A continuous forward current up to 150 °C junction temperature. The matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum non-repetitive reverse blocking voltage; defines safe operating range in 24 V system clamping and flyback snubbers
I_F	10 A - Continuous average forward current at T_C = 100 °C; supports sustained power delivery in compact converter designs
I_FSM	125 A - Peak surge current for 8.3 ms half-sine; handles inrush and fault transients in motor drives and battery chargers
V_F	1.1 V max @ 5 A, 25 °C - Low conduction loss reduces thermal load and improves efficiency in high-duty-cycle rectification
R_θJC	3 °C/W - Enables direct heatsink mounting with predictable thermal rise; simplifies thermal design for 10 A operation
T_J max	150 °C - Rated junction temperature allows operation in under-hood automotive environments without derating

Pinout & Package

Package: TO-220AB - Three-terminal, through-hole, insulated tab package with center cathode pinout; case electrically isolated from terminals per UL 94V-0 molding compound.

Pin/Terminal	Circuit Role	Design Meaning
Anode 1	Input terminal for first rectifier die	Accepts AC or switched input; requires external connection to source/switch node
Cathode (center)	Common output node for both dies	Shared cathode enables dual-anode, single-output configuration; mounted to heatsink

FAQ

What is the peak repetitive reverse voltage rating for GP1003H?

The GP1003H has a peak repetitive reverse voltage (V_RRM) rating of 200 V. This value is specified in the Absolute Maximum Ratings table and confirmed across all official documentation versions (G2104). It defines the maximum reverse-biased voltage the device can block continuously without breakdown under normal operating conditions. Designers must ensure circuit transient voltages remain below this threshold, especially in automotive 24 V systems with load dump spikes.

Is GP1003H qualified to AEC-Q101 standards?

Yes, GP1003H is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section. This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling. The GP1003H meets these requirements for use in automotive power electronics, unlike non-H variants such as GP1003.

What is the forward voltage drop of GP1003H at rated current?

The GP1003H exhibits a maximum forward voltage (V_F) of 1.1 V at 5 A and 25 °C junction temperature, per Electrical Specifications. At full-rated 10 A, V_F increases due to resistive heating but remains within design margins for efficient operation. This low V_F directly reduces conduction losses and thermal stress compared to higher-V_F alternatives like MUR1020CT (1.3 V).

Does GP1003H have a dual-die configuration, and how is it implemented?

Yes, GP1003H uses a dual-die configuration housed in a single TO-220AB package, with two independent anodes and a shared cathode terminal. This is confirmed in the KEY PARAMETERS section and Mechanical Data. The dual-die layout enables either independent channel operation or paralleled conduction-offering flexibility in redundancy, interleaving, or split-input topologies without increasing PCB footprint.

What is the thermal resistance from junction to case for GP1003H?

The GP1003H has a typical junction-to-case thermal resistance (R_θJC) of 3 °C/W, as specified in the THERMAL PERFORMANCE section. This value is measured under standard mounting conditions with proper heatsink interface. It enables reliable 10 A operation with manageable temperature rise-e.g., a 30 °C rise at 10 W dissipation-supporting passive cooling in space-limited industrial and automotive modules.
