Taiwan Semiconductor Corporation GP1604

Overview

GP1604 from Taiwan Semiconductor is a 16A, 400V repetitive peak reverse voltage (V_RRM) standard rectifier diode in TO-220AB package, featuring dual-die configuration, 150A surge capability (I_FSM), and 1.1V max forward voltage at 8A/25°C. It serves as primary AC/DC rectification element in high-efficiency power supplies for industrial SMPS.

For engineers reviewing the GP1604 datasheet, GP1604 pinout, GP1604 application, or GP1604 equivalent, key selection criteria include V_RRM = 400V, I_F = 16A continuous, thermal resistance R_θJC = 1.5°C/W, AEC-Q101 qualification availability (GP1604H), and TO-220AB mechanical compatibility with heatsink mounting.

Technical Context

This standard rectifier operates as a unidirectional current-conducting device with two independent PN junctions housed in a single TO-220AB case. Its dual-die structure enables parallel conduction paths without internal series connection, supporting higher current handling than single-die equivalents of comparable voltage rating.

Thermal performance is defined by R_θJC = 1.5°C/W and maximum junction temperature of 150°C, enabling operation up to 125°C case temperature under derated current conditions. Reverse leakage remains ≤10 µA at 25°C and ≤250 µA at 125°C at rated V_R, ensuring stable blocking in high-temperature environments.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated semiconductor manufacturer specializing in discrete power devices, including rectifiers, TVS diodes, and MOSFETs, with global distribution and AEC-Q101 qualification capability.

The GP1601–GP1607 family was designed for cost-effective, thermally robust AC/DC and DC/DC rectification in industrial, computing, and automotive power systems where reliability under sustained current and surge stress is critical.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for GP1604?

The GP1604 has a V_RRM rating of 400 V, meaning it can reliably block up to 400 V of reverse voltage in repetitive operation. This value is specified in the Absolute Maximum Ratings table and confirmed across all official TSC documentation for GP1604. Exceeding this voltage risks irreversible avalanche breakdown. The GP1604's 400 V rating places it between GP1603 (200 V) and GP1605 (600 V) in the same family.

Does GP1604 have a common-cathode or common-anode configuration?

The GP1604 uses a common-cathode configuration with two independent anodes and one shared cathode terminal. This is explicitly shown in the marking diagram and package outline, and enables full-wave rectification with center-tapped transformers. The TO-220AB pinout confirms Cathode as the middle lead, Anode 1 and Anode 2 as outer leads - a layout distinct from common-anode variants like GP1604A (not offered in this family).

Is GP1604 suitable for automotive applications?

Yes - the GP1604H variant is AEC-Q101 qualified and approved for automotive use, while the base GP1604 is not. GP1604H undergoes additional stress testing including temperature cycling, humidity bias, and mechanical shock per AEC-Q101 Rev D. For under-hood or infotainment power supplies, GP1604H must be specified; standard GP1604 lacks the required qualification documentation and screening.

What is the thermal resistance (R_θJC) of GP1604 and how does it affect heatsink design?

The GP1604 has a junction-to-case thermal resistance of 1.5°C/W, measured from die to mounting surface. This low value allows efficient heat transfer to an external heatsink, enabling 16 A continuous operation at T_C = 75°C. When designing heatsinks, total thermal resistance (R_θJA) must account for interface material and airflow; for example, a 5°C/W heatsink yields ~105°C junction rise at 16 A, staying within the 150°C T_JMAX limit.

How does GP1604 compare to ultrafast rectifiers like MUR1640CT in switching performance?

GP1604 is a standard recovery rectifier with reverse recovery time >1 µs, optimized for conduction efficiency rather than speed. In contrast, MUR1640CT is an ultrafast rectifier with t_rr ≈ 60 ns, minimizing switching loss in high-frequency (>100 kHz) topologies. GP1604's lower V_F (1.1 V vs. 1.25 V) and better R_θJC make it preferable in 50–100 kHz industrial SMPS where recovery loss is secondary to thermal management.
