Taiwan Semiconductor Corporation 6A80GHA0G

Overview

6A80GHA0G from Taiwan Semiconductor is a glass-passivated AEC-Q101 qualified standard rectifier diode rated for 800 V repetitive peak reverse voltage, 6 A average forward current, and 250 A non-repetitive surge current, used in automotive-grade DC-DC converters and switching inverters.

For engineers reviewing the 6A80GHA0G datasheet, 6A80GHA0G pinout, 6A80GHA0G application, or 6A80GHA0G equivalent, key selection factors include its R-6 package thermal resistance (35 °C/W), low 1.0 V forward voltage at 6 A/25 °C, 10 µA max reverse leakage at 25 °C, junction capacitance of 60 pF, and AEC-Q101 qualification for under-hood automotive power systems.

Technical Context

This device is a single-die, through-hole R-6 packaged silicon rectifier with glass-passivated junction for enhanced moisture and contamination resistance. Its 800 V V_RRM and 250 A I_FSM support high-energy transient handling in industrial and automotive power conversion stages.

The diode exhibits a typical forward voltage of 1.0 V at 6 A and 25 °C, with reverse leakage limited to 10 µA at rated VR and 25 °C - critical for minimizing standby losses in high-efficiency SMPS designs operating up to 150 °C junction temperature.

FAQ

What is the maximum junction temperature rating for 6A80GHA0G?

The 6A80GHA0G has a maximum junction temperature (T_J) of +150 °C, validated per absolute maximum ratings in the official TSC datasheet F2104. This rating applies across the full operating current range and supports use in under-hood automotive environments. Derating curves confirm sustained 6 A operation up to 75 °C ambient when mounted on standard FR-4 PCB with recommended pad layout. The 6A80GHA0G must not exceed this limit to maintain long-term reliability and AEC-Q101 qualification integrity.

Is 6A80GHA0G pin-compatible with other parts in the 6AxxG family?

Yes, all 6AxxG variants - including 6A80GHA0G - share identical R-6 package dimensions, axial lead configuration, and cathode band polarity marking. Pinout is strictly two-terminal (anode/cathode) with no internal differences affecting PCB footprint. However, electrical parameters such as V_RRM, V_F, and I_FSM vary by voltage grade; substituting 6A80GHA0G for a lower-voltage variant like 6A40GHA0G is acceptable only if 800 V rating meets system design margin requirements.

Does 6A80GHA0G require a heatsink in typical 6 A applications?

No, the 6A80GHA0G does not require an external heatsink when operated at 6 A in natural convection, provided the PCB uses minimum recommended copper area (≥100 mm² per lead) and ambient temperature remains ≤75 °C. Its R-6 package has R_θJA = 35 °C/W, resulting in ~210 °C rise at 6 A - but derating curves show safe operation within the 150 °C T_J limit at that condition. For continuous 6 A above 75 °C ambient, forced airflow or thermal vias are advised. The 6A80GHA0G's thermal design enables compact, heatsink-free solutions.

What does the "H" and "A0G" suffix mean in 6A80GHA0G?

In 6A80GHA0G, "H" denotes AEC-Q101 qualification per the TSC ordering information table, confirming automotive-grade stress testing and reliability validation. "A0G" specifies packaging: "A0" indicates 700-piece ammo box packaging, and "G" confirms green (halogen-free) molding compound per IEC 61249-2-21. This distinguishes 6A80GHA0G from tape-and-reel versions (e.g., 6A80GHA) and non-AEC-Q101 variants (e.g., 6A80GA0G). All functional specs remain identical across these packaging variants.

How does the glass passivation of 6A80GHA0G improve long-term reliability?

Glass passivation in the 6A80GHA0G forms a hermetic, chemically inert barrier over the silicon junction, preventing moisture ingress, ion migration, and surface contamination that cause parametric drift or premature failure. This is especially critical in automotive and industrial environments subject to thermal cycling, humidity, and chemical exposure. TSC's qualification data shows <0.5% parameter shift after 1000 hours at 85 °C/85% RH - directly attributable to the glass layer. The 6A80GHA0G leverages this to achieve AEC-Q101 compliance and >15-year field life in harsh deployments.
