Taiwan Semiconductor Corporation 6A80G B0G

Overview

6A80G from Taiwan Semiconductor is a glass-passivated standard rectifier diode rated for 800 V repetitive peak reverse voltage, 6 A average forward current, and 250 A surge capability, with 1.0 V typical forward voltage at 6 A and 25°C - used in high-reliability DC-DC converters and switching inverters.

For engineers reviewing the 6A80G datasheet, 6A80G pinout, 6A80G application, or 6A80G equivalent, key selection factors include its R-6 package thermal resistance (35°C/W), AEC-Q101 qualification option (6A80GH), junction temperature range (–55°C to +150°C), and low leakage (<10 µA at 25°C).

Technical Context

This single-die standard rectifier operates as a unidirectional power conversion device in AC/DC and DC/DC stages, featuring glass passivation for moisture and contamination resistance, pure tin-plated leads compliant with J-STD-002, and a cathode band polarity indicator.

Its thermal design supports continuous operation up to TJ = 150°C with RθJA = 35°C/W, and electrical behavior is characterized by low forward voltage (1.0 V typ. at 6 A), low junction capacitance (60 pF at 4 V), and stable reverse leakage (<100 µA at 125°C).

FAQ

What is the maximum repetitive peak reverse voltage (VRRM) for the 6A80G?

The 6A80G has a VRRM rating of 800 V, meaning it can reliably block up to 800 V of reverse voltage in repetitive operation without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version F2104), and applies across the full operating temperature range from –55°C to +150°C. The 6A80G is part of the 6A05G–6A100G family where "80" denotes the 800 V rating.

Does the 6A80G have AEC-Q101 qualification?

The base 6A80G is not AEC-Q101 qualified, but the pin- and package-identical variant 6A80GH is fully AEC-Q101 qualified. Per TSC's ordering information, the "H" suffix indicates qualification for automotive applications including stress tests for temperature cycling, humidity, and mechanical shock. Engineers selecting 6A80G for automotive use must specify 6A80GH to ensure compliance.

What is the typical forward voltage (VF) of the 6A80G at 6 A and 25°C?

The typical forward voltage of the 6A80G is 1.0 V at IF = 6 A and TJ = 25°C, as specified in the Electrical Specifications table (Version F2104). This value is measured under pulsed conditions (PW = 0.3 ms) and represents the conduction loss baseline for thermal and efficiency calculations. It is lower than earlier family members like 6A05G (1.1 V typ.), reflecting optimized die design for higher-voltage variants.

What package type does the 6A80G use, and what are its key mechanical features?

The 6A80G uses the R-6 axial-leaded package, defined in TSC's Package Outline Dimensions (Version F2104). Key features include UL 94V-0 flammability-rated molding compound, pure tin-plated leads compliant with J-STD-002, cathode polarity indicated by a band, and a typical weight of 1.65 g. Its RθJA is 35°C/W, making it suitable for through-hole PCB mounting with moderate copper area for thermal relief.

How does the 6A80G compare to the 6A60G in terms of voltage rating and forward voltage?

The 6A80G is rated for 800 V VRRM and exhibits 1.0 V typical VF at 6 A and 25°C, whereas the 6A60G is rated for 600 V VRRM and shares the same 1.0 V VF spec. Both belong to the same family and share identical package, thermal, and surge ratings (250 A IFSM), differing only in blocking voltage and marking code. Designers upgrading from 6A60G to 6A80G gain 200 V margin without changing layout or thermal design.
