Product details

Overview

6A80GHB0G from Taiwan Semiconductor is a glass-passivated, AEC-Q101 qualified standard rectifier diode in R-6 package, rated for 800 V repetitive peak reverse voltage (V_RRM), 6 A average forward current (I_F), and 250 A non-repetitive surge current (I_FSM). It delivers low forward voltage drop (1.0 V at 6 A, 25°C) and operates up to 150°C junction temperature, targeting high-reliability power conversion in automotive and industrial DC/DC converters.

For engineers reviewing the 6A80GHB0G datasheet, 6A80GHB0G pinout, 6A80GHB0G application, or 6A80GHB0G equivalent, key selection criteria include its AEC-Q101 qualification, R-6 package thermal resistance (35°C/W), 10 µA max reverse leakage at 25°C, 60 pF junction capacitance, and compatibility with lead-free reflow per J-STD-002.

Technical Context

This device is a single-die, through-hole standard rectifier optimized for switching-mode power supplies where reliability under thermal stress and transient surge conditions is critical. Its glass-passivated junction ensures stable performance across -55°C to +150°C operating range and supports high-surge capability without degradation.

The R-6 package features pure tin-plated leads, UL 94V-0 molding compound, and cathode band polarity marking. Thermal resistance of 35°C/W (junction-to-ambient) enables operation at full 6 A load in moderate airflow environments without forced cooling.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - Maximum reverse blocking voltage before breakdown; defines usable input voltage range in AC/DC front-ends and DC/DC isolation stages.
I_F	6 A - Continuous average forward current rating at 75°C ambient; determines steady-state power handling in rectification paths.
I_FSM	250 A - Peak non-repetitive surge current (8.3 ms half-sine); supports robustness against line transients and inrush events.
V_F	1.0 V @ 6 A, 25°C - Low conduction loss reduces heat generation and improves efficiency in high-current rectifier legs.
R_θJA	35 °C/W - Junction-to-ambient thermal resistance; informs heatsinking requirements for sustained 6 A operation in enclosed enclosures.
C_J	60 pF @ 1 MHz, 4 V - Junction capacitance affects high-frequency switching noise and EMI filter design in SMPS applications.

Pinout & Package

R-6 package: axial-leaded, molded plastic case with cathode band marking; RoHS-compliant, halogen-free, UL 94V-0 rated; weight ≈1.65 g; terminals solderable per J-STD-002.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead 1)	Forward current entry point	Connected to lower-potential side of AC source or transformer secondary; must withstand surge currents and thermal cycling.
Cathode (Lead 2, marked by band)	Forward current exit point	Connected to output bus or smoothing capacitor; polarity marking prevents reverse installation in high-voltage circuits.

Key Features

AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, HTRB, and surge testing per JEDEC standards.
Glass-passivated junction	Eliminates moisture-induced leakage and surface degradation, enabling stable IR < 10 µA over lifetime in humid environments.
Low V_F (1.0 V)	Reduces conduction losses by ~15% vs. comparable 800 V rectifiers, lowering thermal stress on PCB traces and adjacent components.
High I_FSM/I_F ratio (41.7:1)	Supports >40× overload tolerance-critical for handling cold-start surges in automotive DC/DC modules without derating.

Equivalent & Alternatives

The following parts are listed as comparable options for similar standard rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH6R08D	800 V V_RRM, 6 A I_F, but TO-220AC package (R_θJA = 50°C/W); VF = 1.15 V @ 6 A	Requires heatsink for same 6 A continuous load; not AEC-Q101 qualified	Prefer when board space allows TO-220 mounting and automotive qualification is unnecessary.
ON Semi MUR680CT	800 V V_RRM, dual common-cathode configuration; VF = 1.25 V @ 6 A; no AEC-Q101 grade available	Designed for center-tapped transformer rectification; higher VF increases conduction loss	Select only if dual-diode topology matches existing schematic and thermal budget permits 0.25 V higher drop.

Compared with STTH6R08D and MUR680CT, 6A80GHB0G uniquely combines AEC-Q101 qualification, R-6 axial package with 35°C/W thermal resistance, and 1.0 V forward voltage-making it optimal for space-constrained, thermally demanding automotive and industrial rectifier applications where reliability and efficiency are jointly prioritized.

FAQ

What is the maximum junction temperature rating for 6A80GHB0G?

The 6A80GHB0G has a maximum junction temperature (T_J) rating of +150°C, verified per JEDEC JESD22-A108 and supported by its glass-passivated die construction and R-6 package thermal performance. This allows reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 100°C. The 6A80GHB0G maintains specified electrical parameters-including 10 µA reverse leakage at 125°C-within this full temperature range.

Is 6A80GHB0G compatible with lead-free reflow soldering processes?

Yes, 6A80GHB0G features pure tin-plated leads and is rated for solderability per J-STD-002. Its R-6 package withstands peak reflow temperatures up to 260°C for 10 seconds, meeting IPC/JEDEC J-STD-020 requirements for lead-free assembly. The UL 94V-0 molding compound remains dimensionally stable during thermal cycling, and the device's 150°C T_J rating ensures no internal degradation occurs during standard reflow profiles used for automotive PCBs.

Does 6A80GHB0G have a documented AEC-Q101 qualification report?

Yes, 6A80GHB0G is explicitly designated as AEC-Q101 qualified in Taiwan Semiconductor's official documentation (Version F2104), with test records covering HTGB, HTRB, TCT, and surge testing per AEC-Q101-004 and AEC-Q101-007. The "H" suffix in the part number confirms qualification status, and the device meets all stress test limits-including 1000 hours at 150°C and 250 A surge-without parameter drift beyond specification limits.

What is the reverse leakage current specification for 6A80GHB0G at elevated temperature?

At 25°C, 6A80GHB0G exhibits ≤10 µA reverse leakage current (I_R) at rated V_RRM (800 V); at 125°C, the maximum specified I_R is 100 µA under the same conditions. These values are measured using 30 ms pulse testing per datasheet Note 2 and reflect stable performance of the glass-passivated junction under thermal stress-critical for minimizing standby power loss in always-on automotive modules.

How does the 6A80GHB0G differ from non-AEC-Q101 versions like 6A80G?

The 6A80GHB0G differs from standard 6A80G solely by its AEC-Q101 qualification-confirmed via additional reliability testing (HTGB, TCT, surge), lot traceability, and process controls mandated for automotive use. Electrically and thermally identical, both share identical V_RRM (800 V), I_F (6 A), V_F (1.0 V), and R-6 package. The "H" suffix and "B0G" suffix denote AEC-Q101 grade and green compound, respectively-no parameter or pinout differences exist between 6A80G and 6A80GHB0G.
