Taiwan Semiconductor Corporation GPA805 C0G

Overview

GPA805 C0G from Taiwan Semiconductor is a single-die, glass-passivated standard rectifier diode rated for 600 V repetitive peak reverse voltage (V_RRM), 8 A average forward current (I_F), and 150 A non-repetitive surge current (I_FSM), used in DC-DC converters and switching-mode inverters where high reliability and low forward voltage are critical.

For engineers reviewing the GPA805 C0G datasheet, GPA805 C0G pinout, GPA805 C0G application, or GPA805 C0G equivalent, key selection criteria include verified V_RRM = 600 V, I_F = 8 A, V_F ≤ 1.1 V @ 8 A/25°C, R_θJC = 2.5 °C/W, and TO-220AC package compatibility with industrial thermal management requirements.

Technical Context

The GPA805 C0G implements a single-junction, planar-glass-passivated silicon rectifier structure optimized for high-efficiency power conversion. Its 600 V V_RRM rating and 150 A I_FSM support robust operation under transient overloads in SMPS primary-side rectification.

Thermal performance is defined by a junction-to-case resistance of 2.5 °C/W and a maximum junction temperature of +150°C, enabling stable operation at elevated ambient temperatures when mounted on standard heatsinks per TO-220AC mechanical specifications.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for GPA805 C0G?

The GPA805 C0G has a V_RRM of 600 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version G2103). This rating defines the highest reverse voltage the device can block repeatedly without breakdown and is validated across the full operating temperature range (–55°C to +150°C). The GPA805 C0G is part of the GPA801–GPA807 series, where each suffix digit corresponds to a specific V_RRM step (e.g., GPA801 = 50 V, GPA805 = 600 V).

Is GPA805 C0G AEC-Q101 qualified?

The base GPA805 C0G is not AEC-Q101 qualified; however, the AEC-Q101 variant is explicitly designated GPA805H per the Ordering Information section. Both share identical electrical and thermal specifications, but only GPA805H undergoes the full stress-test sequence per AEC-Q101 Rev D, including temperature cycling, highly accelerated life testing, and ESD verification. GPA805 C0G remains suitable for industrial applications where automotive qualification is not mandated.

What is the forward voltage (V_F) of GPA805 C0G at rated current?

The GPA805 C0G exhibits a maximum forward voltage of 1.1 V at I_F = 8 A and T_J = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At elevated junction temperatures (e.g., 125°C), V_F decreases slightly due to the negative temperature coefficient of silicon diodes, supporting stable operation in thermally demanding layouts.

Which package does GPA805 C0G use, and is the case electrically active?

GPA805 C0G uses the TO-220AC package, with the metal tab serving as the cathode terminal-making it electrically active and thermally conductive. Per the Mechanical Data section, the case is polarity-marked and must be electrically isolated from the heatsink unless the circuit design intentionally references the cathode to chassis ground. The leads are matte tin-plated and solderable per J-STD-002, and the molding compound meets UL 94V-0.

How does GPA805 C0G compare to GPA804 and GPA806 in terms of voltage rating?

GPA805 C0G is rated for 600 V V_RRM, positioned between GPA804 (400 V) and GPA806 (800 V) in the GPA801–GPA807 series. All share identical I_F = 8 A, I_FSM = 150 A, and TO-220AC packaging, differing only in blocking voltage capability and corresponding reverse leakage (I_R). This allows direct substitution within a design's voltage margin-e.g., GPA805 C0G replaces GPA804 if system transients exceed 400 V, without changing layout or thermal interface.
