Taiwan Semiconductor Corporation 6A80G

Overview

6A80G from Taiwan Semiconductor is a 6 A, 800 V glass-passivated standard rectifier diode in R-6 package, featuring 1.0 V forward voltage at 6 A and 250 A surge capability, used in high-reliability switching mode power supplies and DC-DC converters.

For engineers reviewing the 6A80G datasheet, 6A80G pinout, 6A80G application, or 6A80G equivalent, key selection criteria include repetitive peak reverse voltage (800 V), forward current rating (6 A), thermal resistance (35 °C/W), junction capacitance (60 pF), and AEC-Q101 qualification availability.

Technical Context

This single-die standard rectifier operates with a maximum junction temperature of 150 °C and supports continuous forward conduction up to 6 A at ambient conditions, with thermal performance defined by a junction-to-ambient resistance of 35 °C/W under standard mounting.

Its electrical behavior includes low forward voltage drop (1.0 V typ. at 6 A, 25 °C), low leakage (10 µA max at 25 °C, 100 µA max at 125 °C), and stable junction capacitance (60 pF at 1 MHz, 4 V reverse bias), enabling efficient high-frequency rectification in SMPS designs.

FAQ

What is the maximum repetitive peak reverse voltage rating for the 6A80G?

The 6A80G has a maximum repetitive peak reverse voltage (VRRM) rating of 800 V, verified per Taiwan Semiconductor's F2104 datasheet. This rating allows safe operation in 600 VDC bus applications with 33% voltage margin. The 6A80G maintains this rating across its full operating junction temperature range of –55 °C to +150 °C.

Does the 6A80G have AEC-Q101 qualification?

The base 6A80G is not AEC-Q101 qualified; however, the variant 6A80GH is explicitly qualified per AEC-Q101 Rev D. The "H" suffix denotes automotive-grade screening, including extended temperature cycling, high-temperature operating life, and mechanical shock testing. For automotive use, specify 6A80GH-not 6A80G-when ordering.

What is the forward voltage drop of the 6A80G at rated current?

The 6A80G exhibits a typical forward voltage (VF) of 1.0 V at 6 A and 25 °C, as measured under pulse conditions (PW = 0.3 ms). At elevated junction temperatures (125 °C), VF decreases slightly due to negative temperature coefficient. This value is confirmed in the Electrical Specifications table of the official F2104 datasheet.

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

The 6A80G uses the R-6 axial leaded package with pure tin-plated leads compliant with J-STD-002 solderability standards. Its molding compound meets UL 94V-0 flammability rating, and it passes JESD201 Class 2 whisker testing. The device weighs approximately 1.65 g and features cathode polarity indicated by a visible band.

How does the thermal resistance of the 6A80G affect PCB layout decisions?

The 6A80G has a junction-to-ambient thermal resistance (RθJA) of 35 °C/W under standard test conditions. To maintain TJ ≤ 150 °C at 6 A continuous current, PCB copper area must dissipate ≤70 °C rise above ambient. This typically requires ≥250 mm² of 2 oz copper connected to both leads, verified via thermal simulation or empirical testing per JEDEC 51-7.
