Taiwan Semiconductor Corporation GP1005

Overview

GP1005 from Taiwan Semiconductor is a 10A, 600V standard rectifier diode in TO-220AB package with dual-die configuration, low forward voltage (1.1V @ 5A), 125A surge rating, and AEC-Q101 qualification option. It serves as primary AC/DC input rectification in high-efficiency power supplies for industrial motor drives.

For engineers reviewing the GP1005 datasheet, GP1005 pinout, GP1005 application, or GP1005 equivalent, key selection criteria include repetitive peak reverse voltage (600V), junction-to-case thermal resistance (3°C/W), forward voltage consistency across temperature, and compatibility with TO-220AB heatsink mounting requirements.

Technical Context

This device implements a dual-die standard PN junction rectifier structure optimized for continuous conduction mode operation in offline switch-mode power supplies. Its 600V V_RRM, 10A average forward current, and 125A non-repetitive surge rating support robust bridge or single-phase rectifier designs.

Thermal performance is defined by a 3°C/W junction-to-case resistance and 150°C maximum junction temperature, enabling stable operation under forced-air or heatsink-cooled conditions. Reverse leakage remains ≤5µA at 25°C and ≤200µA at 125°C at rated 600V reverse bias.

FAQ

What is the maximum junction temperature rating for GP1005?

The GP1005 has a maximum junction temperature (T_J) rating of +150°C, verified across its full operating range from –55°C to +150°C. This specification enables reliable operation in high-ambient environments such as enclosed industrial enclosures or under-hood automotive locations. The GP1005 maintains parameter integrity up to this limit when thermal design respects the 3°C/W R_θJC and appropriate heatsinking is applied.

Does GP1005 have AEC-Q101 qualification?

Yes, GP1005H is the AEC-Q101 qualified variant of GP1005, explicitly listed in the ordering information. Standard GP1005 is not AEC-Q101 certified; only the "H" suffix version undergoes full automotive stress testing per JESD22-A110/A111. For automotive applications, GP1005H must be specified to ensure compliance with temperature cycling, HTRB, and ESD requirements.

What is the reverse leakage current of GP1005 at elevated temperature?

At 125°C junction temperature and rated 600V reverse voltage, GP1005 exhibits a maximum reverse leakage current (I_R) of 200 µA per diode, as confirmed in the Electrical Specifications table. This value is measured using a 30ms pulse test and reflects worst-case behavior under sustained high-temperature operation-critical for evaluating standby power loss in always-on systems.

Can GP1005 be used in full-wave bridge configurations?

Yes, GP1005's dual-die common-cathode configuration allows direct implementation in center-tapped full-wave rectifiers without external diode pairing. Each die operates independently with identical 600V V_RRM and 10A I_F ratings. When used in such topologies, both dies share the same cathode (tab and lead 2), simplifying PCB layout and reducing component count versus discrete single-die alternatives.

What is the thermal resistance from junction to case for GP1005?

The GP1005 has a typical junction-to-case thermal resistance (R_θJC) of 3°C/W, as published in the Thermal Performance section. This value is measured under standardized JEDEC conditions and enables precise case temperature estimation when mounted to a heatsink with known interface resistance. Designers should use this figure-not R_θJA-for thermal modeling in mechanically constrained layouts.
