Taiwan Semiconductor Corporation 6A100G

Overview

6A100G from Taiwan Semiconductor is a single-die, glass-passivated standard rectifier diode rated for 1000 V repetitive peak reverse voltage (V_RRM), 6 A average forward current (I_F), and 250 A non-repetitive surge current (I_FSM), used in high-voltage DC-DC converters and switching inverters.

For engineers reviewing the 6A100G datasheet, 6A100G pinout, 6A100G application, or 6A100G equivalent, key selection factors include its R-6 axial package, 1.0 V typical forward voltage at 6 A/25°C, 10 µA max reverse leakage at 25°C, 35 °C/W junction-to-ambient thermal resistance, and AEC-Q101 qualification option (6A100GH).

Technical Context

The 6A100G operates as a unidirectional power rectifier with a single PN junction, optimized for high-voltage switching-mode power supplies. Its glass passivation ensures stable surface insulation under thermal cycling and humidity stress, while the R-6 package supports axial through-hole mounting with pure tin-plated leads compliant to J-STD-002 solderability.

Thermal performance is defined by a 35 °C/W R_θJA, enabling 6 A continuous conduction up to 150 °C junction temperature when adequately heatsinked. Reverse recovery behavior is not specified - confirming it is a standard (non-fast, non-soft) recovery rectifier suitable for line-frequency and moderate-frequency (<100 kHz) applications.

FAQ

What is the maximum junction temperature rating for the 6A100G?

The 6A100G has a maximum junction temperature (T_J) of +150°C, with a storage temperature range of –55°C to +150°C. This rating allows operation in demanding environments such as industrial motor drives and automotive on-board chargers when mounted on sufficient copper area or heatsinking. Thermal design must respect the 35 °C/W R_θJA to avoid exceeding this limit under 6 A load.

Does the 6A100G have AEC-Q101 qualification?

The base 6A100G is not AEC-Q101 qualified; however, the variant 6A100GH is explicitly qualified per AEC-Q101. The "H" suffix denotes automotive-grade testing including temperature cycling, highly accelerated stress test (HAST), and mechanical shock validation. For automotive applications requiring qualification, specify 6A100GH - the 6A100G itself remains suitable for industrial use only.

What is the forward voltage of the 6A100G at rated current?

The 6A100G exhibits a typical forward voltage (V_F) of 1.0 V at 6 A and 25°C junction temperature, measured under pulse conditions (PW = 0.3 ms). At elevated temperatures or DC conditions, V_F decreases slightly due to negative temperature coefficient, but system-level thermal design must account for ~6 W conduction loss at full load.

Is the 6A100G pin-compatible with other R-6 rectifiers like GBU6K?

Yes - the 6A100G uses the standard R-6 axial package with identical lead spacing, diameter, and cathode band marking as GBU6K and other JEDEC DO-15–compliant rectifiers. Mechanical fit and soldering process are interchangeable; however, always verify electrical parameters (especially reverse leakage and thermal derating) before substitution in production designs.

What does the "x" in the ordering code 6AxG represent for the 6A100G?

In the ordering code 6AxG, the "x" encodes the peak reverse voltage rating: for 6A100G, "100" means 1000 V V_RRM. This follows TSC's family coding scheme where 6A05G = 50 V, 6A10G = 100 V, and so on - allowing consistent board design across voltage grades while maintaining identical package, thermal, and current ratings.
