Product details
Overview
6A80GH from Taiwan Semiconductor is a glass-passivated, AEC-Q101 qualified standard rectifier diode rated for 800 V repetitive peak reverse voltage (VRRM), 6 A average forward current (IF), and 250 A non-repetitive surge current (IFSM), used in automotive-grade DC-DC converters and switching inverters.
For engineers reviewing the 6A80GH datasheet, 6A80GH pinout, 6A80GH application, or 6A80GH equivalent, key selection criteria 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, 60 pF junction capacitance, and AEC-Q101 qualification for under-hood automotive power systems.
Technical Context
This single-die standard rectifier operates with a maximum junction temperature of 150 °C and supports ambient temperatures from –55 °C to +150 °C. Its glass-passivated junction ensures high reliability and robustness against moisture and contamination.
The device delivers low conduction loss due to its 1.0 V typical forward voltage at rated 6 A and 25 °C, while maintaining low reverse leakage (≤10 µA @ 25 °C, ≤100 µA @ 125 °C) across its full 800 V VRRM rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - blocks up to 800 V reverse voltage without breakdown, suitable for 400 VAC input rectification with safety margin |
| IF | 6 A - continuous average forward current handling capacity at case temperature ≤75 °C |
| IFSM | 250 A - withstands short-duration 8.3 ms half-sine surges, critical for inrush and fault protection |
| VF @ 6 A, 25 °C | 1.0 V - low conduction loss enables high-efficiency power conversion in SMPS designs |
| RθJA | 35 °C/W - thermal resistance from junction to ambient in free-air, defines heatsinking requirements |
| IR @ 800 V, 25 °C | ≤10 µA - minimal leakage preserves efficiency in high-impedance bias networks |
| CJ @ 1 MHz, 4 V | 60 pF - limits high-frequency switching noise and EMI in fast-switching topologies |
Pinout & Package
Package: R-6 molded epoxy case with pure tin-plated leads, UL 94V-0 rated, polarity indicated by cathode band, weight ≈1.65 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of AC source or switch node; must handle full 6 A RMS and 250 A surge |
| Cathode | Forward current exit point | Connected to output bus or filter capacitor; marked by visible band; carries same current as anode |
Key Features
| Feature | Design Value |
|---|---|

| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS directives for environmentally restricted electronics manufacturing |
Applications
| Automotive DC-DC Converters | Industrial Switch-Mode Inverters |
|---|---|
Use Scenario: High-reliability 12 V to 48 V bidirectional DC-DC conversion in 48 V mild-hybrid vehicles. IC Role / Device Role / Timing Role: Primary output rectifier in synchronous or asynchronous buck-boost topology. Use Value: AEC-Q101 qualification and 150 °C TJ max ensure stable operation near engine compartments; 1.0 V VF minimizes heat generation in sealed enclosures. | Use Scenario: Output stage rectification in 3 kW industrial UPS inverters with 400 VDC bus. IC Role / Device Role / Timing Role: Freewheeling and output rectification in full-bridge inverter output stage. Use Value: 250 A IFSM handles motor startup surges; 800 V VRRM provides 2× safety margin over 400 VDC bus, reducing failure risk during line transients. |

IC Role / Device Role / Timing Role: Unidirectional current path enabling hot-swap redundancy without reverse current flow. Use Value: Low 1.0 V VF reduces voltage drop and power loss per diode; R-6 package allows manual rework and automated placement in high-density PCBs. |
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, VF = 1.15 V @ 6 A, RθJA = 40 °C/W | Higher thermal resistance and VF increase conduction loss; requires larger heatsink | Preferred where TO-220 mounting and legacy footprint compatibility are required |
| ON Semi MUR680CT | TO-220AB dual common-cathode, 800 V VRRM, 6 A IF per diode, VF = 1.1 V @ 6 A, AEC-Q101 not specified | Dual configuration enables center-tapped or dual-output designs; lacks automotive qualification | Selected when dual-diode integration reduces board area and cost in non-automotive SMPS |
Compared with STTH6R08D and MUR680CT, the 6A80GH offers lower VF and better thermal performance in the compact R-6 package, with AEC-Q101 validation making it uniquely suited for space-constrained automotive power modules where qualification and reliability are mandatory.

FAQ
What is the maximum junction temperature rating for the 6A80GH?
The 6A80GH has a maximum junction temperature (TJ) rating of +150 °C, verified per JEDEC standards and validated under AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments and high-ambient industrial settings when mounted on appropriate copper area or heatsinks. Thermal derating begins above 75 °C case temperature per the forward current derating curve in the datasheet.
Is the 6A80GH pin-compatible with other devices in the 6AxG series?
Yes - all 6AxG and 6AxGH variants, including 6A80GH, share identical R-6 package dimensions, lead spacing, and anode/cathode terminal configuration. The only differences are VRRM rating (50–1000 V) and forward voltage grading; mechanical and soldering compatibility is fully maintained across the family.
Does the 6A80GH require a heatsink in typical 6 A operation?
At 6 A average forward current and 25 °C ambient, the 6A80GH dissipates approximately 6 W (6 A × 1.0 V). With RθJA = 35 °C/W, this yields a ~210 °C junction rise - exceeding its 150 °C limit. Therefore, a minimum 25 mm² copper pad or external heatsink is required to maintain safe TJ. Derating curves confirm ≤3.5 A is sustainable in free-air at 25 °C.
What does the "H" suffix in 6A80GH signify?
The "H" suffix in 6A80GH explicitly denotes AEC-Q101 qualification per Rev. F2104 of the datasheet. This includes rigorous stress testing for temperature cycling, humidity bias, high-temperature operating life, and mechanical shock - confirming suitability for automotive powertrain and chassis applications. Non-H variants (e.g., 6A80G) lack this qualification.
How does the 6A80GH's junction capacitance affect high-frequency performance?
The 6A80GH exhibits 60 pF typical junction capacitance at 1 MHz and 4 V reverse bias. This value influences reverse recovery behavior and EMI generation in >100 kHz switching circuits. While not optimized for ultrafast recovery, its capacitance is stable across voltage and temperature, supporting predictable snubber design and EMC filtering in 50–200 kHz SMPS applications.
