Product details
Overview
6A80G A0G 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 non-repetitive surge current, with 1.0 V typical forward voltage at 6 A and 25°C. It is used in high-reliability DC-DC converters and switching-mode inverters requiring low power loss and robust thermal performance.
For engineers reviewing the 6A80G A0G datasheet, 6A80G A0G pinout, 6A80G A0G application, or 6A80G A0G equivalent, key selection criteria include VRRM = 800 V, IF = 6 A, IFSM = 250 A, RθJA = 35 °C/W, and R-6 package compatibility with industrial-grade power conversion layouts.
Technical Context
This device is a single-die, axial-lead standard rectifier with glass-passivated junction for enhanced moisture resistance and long-term reliability under thermal cycling. Its 800 V VRRM rating supports use in 400–600 V DC bus systems, and its 1.0 V VF at 6 A enables efficient operation in medium-power SMPS topologies.
The R-6 package delivers 35 °C/W junction-to-ambient thermal resistance and supports 150 °C maximum junction temperature. Reverse leakage remains ≤10 µA at 25°C and ≤100 µA at 125°C, ensuring stable blocking behavior across operating temperature range.
Key Specifications

|---|---|
| VRRM | 800 V - Supports 400–600 V DC input stages without derating in industrial SMPS |
| IF | 6 A - Continuous conduction capability for mid-power rectification up to ~100 W output |
| IFSM | 250 A - Withstands 8.3 ms half-sine surges common in AC line start-up and fault transients |
| VF @ 6 A, 25°C | 1.0 V - Enables <1.2 W conduction loss per diode at full load, reducing heatsink requirements |
| RθJA | 35 °C/W - Allows natural-convection cooling in compact R-6 mounted designs up to ~3.5 W dissipation |
| IR @ 800 V, 125°C | ≤100 µA - Maintains low standby leakage in high-temperature environments like enclosed power supplies |
| Junction capacitance | 60 pF @ 1 MHz, 4 V - Minimizes switching noise coupling in high-frequency rectifier snubbers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6R08D | TO-220AC package, 800 V VRRM, 6 A IF, 1.75 V VF @ 6 A, higher thermal mass but larger footprint | Requires PCB mount and heatsink; better for forced-air-cooled systems >50 W | Select when board space allows TO-220 and higher surge immunity is needed beyond 250 A |
| ON Semi MUR680E | Ultrafast recovery (trr = 60 ns), same R-6 package, 800 V VRRM, 1.25 V VF, higher cost | Suitable for high-frequency PFC and resonant topologies where reverse recovery loss dominates | Select only if switching frequency exceeds 100 kHz and reverse recovery EMI must be minimized |
Compared with STTH6R08D and MUR680E, the 6A80G A0G offers lowest conduction loss in R-6 format and optimal cost-performance balance for 50–100 kHz SMPS, while avoiding ultrafast trade-offs in leakage and price.

FAQ
What is the maximum junction temperature rating for the 6A80G A0G?
The 6A80G A0G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official TSC datasheet F2104. This allows continuous operation in enclosed power supplies with ambient temperatures up to 85°C when properly heatsinked. The 6A80G A0G maintains specified electrical parameters within this range, including ≤100 µA reverse leakage at 125°C junction temperature.
Does the 6A80G A0G have AEC-Q101 qualification?
No, the 6A80G A0G is not AEC-Q101 qualified. However, the pin-compatible 6A80GH variant is explicitly qualified per AEC-Q101 Rev D for automotive applications. The 6A80G A0G shares identical electrical and thermal specifications with the GH version but lacks the extended stress test documentation required for automotive release. For non-automotive industrial use, the 6A80G A0G remains fully suitable.
What does the "A0G" suffix mean in 6A80G A0G?
The "A0G" suffix in 6A80G A0G indicates the packaging option: R-6 package supplied in 700-piece ammo box format. Per TSC ordering information, "A0G" denotes bulk packaging (not tape-and-reel), while "G" alone signifies standard tape-and-reel (1,000 pcs). The "G" also confirms halogen-free molding compound per IEC 61249-2-21, and "A0" specifies the ammo box carrier type.
How does the forward voltage of 6A80G A0G compare across temperature?
The 6A80G A0G exhibits a negative temperature coefficient for forward voltage: VF decreases as junction temperature rises. At 6 A and 25°C, VF is typically 1.0 V; at 125°C, it drops to approximately 0.85 V. This behavior is confirmed in the "Typical Forward Characteristics" curve (Fig.4) of the TSC datasheet F2104 and reduces conduction loss under thermal stress, improving system thermal stability.
Can the 6A80G A0G replace a 6A60G in an existing design?
Yes, the 6A80G A0G can directly replace a 6A60G in most cases, as both share identical R-6 package, pinout, IF = 6 A, IFSM = 250 A, and thermal characteristics. The only difference is VRRM: 6A60G is rated for 600 V, while 6A80G A0G is rated for 800 V. This higher rating provides increased voltage margin and improved reliability in systems with line transients or elevated DC bus voltages, with no layout or thermal changes required.
