Taiwan Semiconductor Corporation GP1003

Overview

GP1003 from Taiwan Semiconductor is a 10A, 200V repetitive peak reverse voltage (V_RRM) standard rectifier diode in TO-220AB package, featuring dual-die construction, 125A surge capability (I_FSM), and 3°C/W junction-to-case thermal resistance - used in DC-DC converters and switching inverters where high-current unidirectional conduction and thermal robustness are required.

For engineers reviewing the GP1003 datasheet, GP1003 pinout, GP1003 application, or GP1003 equivalent, key selection considerations include its 200V V_RRM, 1.1V max forward voltage at 5A, 5µA max reverse leakage at 25°C, TO-220AB mechanical compatibility, and AEC-Q101 qualification availability (GP1003H variant).

Technical Context

The GP1003 is a single-phase, dual-die standard rectifier optimized for line-frequency and medium-frequency switching applications. Its 200V V_RRM rating supports 140V RMS reverse voltage handling, and its 125A I_FSM enables reliable operation under transient overloads typical in power supply startup and fault conditions.

Thermally, the device delivers 3°C/W R_θJC with direct case-to-heatsink mounting via TO-220AB's insulated tab, and operates across –55°C to +150°C junction temperature range. Reverse leakage remains ≤5µA at 25°C and ≤200µA at 125°C under rated V_R.

Key Specifications

Pinout & Package

Package: TO-220AB - insulated case with center tab (cathode), two outer leads (anodes), matte tin-plated terminals compliant with J-STD-002 solderability, UL 94V-0 molding compound, and 0.56 N·m maximum mounting torque.

Equivalent & Alternatives

The following parts are listed as comparable options for similar standard rectifier applications.

Compared with STTH10R06DJF and MUR1020CT, GP1003 offers lower conduction loss (1.1V vs. ≥1.25V), dual-anode flexibility for custom rectifier topologies, and optional AEC-Q101 qualification - making it optimal for space-constrained, thermally demanding, or automotive-grade 200V rectification.

Availability

GP1003 is available at Aetrix Electronics and suitable for DC-DC converters, switching mode inverters, and industrial motor drives requiring stable component supply, long-term manufacturability, and RoHS-compliant sourcing.

Supply support for GP1003 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and power discrete manufacturer headquartered in Hsinchu, Taiwan, serving industrial, computing, and consumer markets since 1979.

The GP100x series is part of TSC's standard rectifier platform designed specifically for high-reliability, medium-voltage power conversion systems where thermal performance, surge robustness, and mechanical ruggedness are prioritized over ultra-fast recovery.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for GP1003?

The GP1003 has a V_RRM rating of 200 V, meaning it can reliably block up to 200 volts of reverse voltage in repetitive operation without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor GP1001–GP1007 datasheet (Version G2104). The GP1003 is part of a family spanning 50V to 1000V, with GP1003 specifically designated for the 200V segment.

Does GP1003 have AEC-Q101 qualification?

The base GP1003 is not AEC-Q101 qualified; however, the GP1003H variant - indicated by the "H" suffix in the ordering code - is fully AEC-Q101 qualified. This qualification covers stress tests including temperature cycling, mechanical shock, and humidity testing per automotive reliability standards. GP1003H maintains identical electrical and thermal specifications as GP1003, differing only in qualification status and marking.

What is the pin configuration of GP1003 in TO-220AB package?

The GP1003 uses a three-terminal TO-220AB package with center tab as cathode (K), left lead as Anode 1 (A1), and right lead as Anode 2 (A2). This dual-anode, common-cathode arrangement supports flexible rectifier topologies. Polarity is marked on the device body, and the tab is electrically isolated from the leads per JEDEC TO-220AB mechanical specification.

What is the forward voltage (V_F) of GP1003 at rated current?

The GP1003 has a maximum forward voltage of 1.1 V at 5 A and 25°C junction temperature, as specified in the Electrical Specifications table. This value reflects conduction loss under typical operating conditions and is measured using a 0.3 ms pulse test. At higher temperatures or currents, V_F increases slightly due to positive temperature coefficient behavior inherent to silicon PN junctions.

How does GP1003 differ from GP1004?

The GP1003 and GP1004 share identical package (TO-220AB), current rating (10 A I_F), surge rating (125 A I_FSM), and thermal resistance (3°C/W), but differ exclusively in repetitive peak reverse voltage: GP1003 is rated for 200 V V_RRM, while GP1004 is rated for 400 V V_RRM. Their forward voltage and leakage characteristics are otherwise matched per datasheet tolerances, enabling direct substitution only when voltage margin permits.
