Product details
Overview
6A40GHB0G from Taiwan Semiconductor is a glass-passivated, AEC-Q101 qualified standard rectifier diode rated for 400 V repetitive peak reverse voltage (VRRM), 6 A average forward current (IF), and 250 A non-repetitive surge current (IFSM), deployed in automotive-grade DC-DC converters and switching inverters.
For engineers reviewing the 6A40GHB0G datasheet, 6A40GHB0G pinout, 6A40GHB0G application, or 6A40GHB0G equivalent, key selection criteria include its R-6 package thermal resistance (RθJA = 35 °C/W), low 1.0 V forward voltage at 6 A/25 °C, 10 µA max reverse leakage at 25 °C, junction temperature range (–55 to +150 °C), and AEC-Q101 qualification status.
Technical Context
This device implements a single-die, planar junction silicon rectifier structure with glass passivation for enhanced moisture and contamination resistance. Its R-6 axial leaded package supports high reliability under thermal cycling and mechanical stress, meeting JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.
The 6A40GHB0G operates across –55 °C to +150 °C junction temperature, delivering stable 1.0 V forward voltage at full 6 A load and 25 °C, while maintaining ≤10 µA reverse current at rated 400 V reverse bias and 25 °C - critical for low-loss power conversion stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage without breakdown; defines usable input voltage headroom in bridge or freewheeling configurations |
| IF | 6 A - continuous average forward current at case temperature ≤75 °C; sets steady-state power handling in rectification paths |
| IFSM | 250 A - peak non-repetitive surge current (8.3 ms half-sine); enables robustness against line transients and inrush events |
| VF | 1.0 V @ 6 A, 25 °C - forward voltage drop directly determines conduction loss (Pcond ≈ 6 W) and thermal load in operation |
| RθJA | 35 °C/W - junction-to-ambient thermal resistance in free-air; used to calculate worst-case junction temperature rise under given power dissipation |
| TJ max | +150 °C - maximum allowable junction temperature; constrains derating curves and heatsinking requirements for long-term reliability |
| IR | ≤10 µA @ 400 V, 25 °C - reverse leakage current; impacts standby power loss and voltage hold-off integrity in high-impedance circuits |
Pinout & Package
Package: R-6 axial-leaded, molded epoxy case with cathode band marking; UL 94V-0 rated, pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential side of AC source or switch node; must withstand full surge current and thermal cycling |
| Cathode (Lead 2, banded end) | Forward current exit / reverse voltage blocking terminal | Connected to output rail or capacitor; polarity marking ensures correct orientation in series/bridge configurations |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS power supplies per stress test requirements |
| Glass passivated junction | Prevents corrosion and leakage path formation under humid or contaminated environments, extending field life in harsh conditions |
| Low VF (1.0 V @ 6 A) | Reduces conduction losses by ~15% vs. comparable 1.15 V diodes, lowering thermal design burden and improving system efficiency |
| R-6 package thermal performance | 35 °C/W RθJA enables 6 A operation without forced air or heatsink in ambient ≤50 °C, simplifying board-level thermal management |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU, supporting environmentally regulated industrial and automotive manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06S | 6 A, 600 V VRRM, TO-220AC package, 1.7 V VF @ 6 A, no AEC-Q101 rating | Higher voltage margin but higher conduction loss; requires heatsink due to TO-220 thermal resistance | Select when >400 V blocking is required and automotive qualification is not mandatory |
| ON Semi MUR640CT | 6 A, 400 V, dual common-cathode configuration in TO-220AB, 1.25 V VF, no AEC-Q101 | Dual-diode layout enables center-tapped transformer rectification; larger footprint and higher VF | Select for dual-output or full-wave center-tap designs where space allows TO-220AB mounting |
Compared with STTH6L06S and MUR640CT, the 6A40GHB0G offers lower forward voltage, AEC-Q101 qualification, and R-6 package compatibility with legacy through-hole layouts - making it optimal for cost-sensitive, thermally constrained automotive and industrial rectifier replacements requiring proven reliability.

FAQ
What is the maximum junction temperature rating for the 6A40GHB0G?
The 6A40GHB0G has a maximum junction temperature (TJ) rating of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version F2104). This rating enables operation in under-hood automotive environments and high-ambient industrial settings. Derating is required above 75 °C case temperature, and thermal design must ensure the 6A40GHB0G stays within this limit under full 6 A load and surge conditions.
Is the 6A40GHB0G pin-compatible with other devices in the 6AxxG series?
Yes - all 6AxxG devices, including the 6A40GHB0G, share identical R-6 package dimensions, axial lead configuration, and cathode-band polarity marking. The only functional differences are VRRM (400 V for 6A40GHB0G) and AEC-Q101 qualification (denoted by "H" suffix). Mechanical fit and PCB footprint are fully interchangeable across the series.
Does the 6A40GHB0G meet halogen-free and RoHS requirements?
Yes - the 6A40GHB0G complies with both RoHS Directive 2011/65/EU and IEC 61249-2-21 for halogen-free materials. The molding compound contains no brominated flame retardants, and the pure tin-plated leads satisfy J-STD-002 solderability standards. These certifications are documented in Taiwan Semiconductor's official product specification (Version F2104).
What is the forward voltage of the 6A40GHB0G at 6 A and 125 °C?
The datasheet specifies VF = 1.0 V maximum at IF = 6 A and TJ = 25 °C. While no exact value is given at 125 °C, typical forward voltage decreases with rising junction temperature - expected to be ~0.85–0.90 V at 125 °C based on silicon diode physics and curve extrapolation from Figure 4 (Typical Forward Characteristics) in the 6A05G–6A100G datasheet. For design, use 1.0 V as worst-case at room temperature.
How is AEC-Q101 qualification reflected in the 6A40GHB0G part number?
The "H" in 6A40GHB0G explicitly denotes AEC-Q101 qualification per Taiwan Semiconductor's ordering code convention (see Ordering Information section, Version F2104). The "B0G" suffix indicates green compound (halogen-free) and tape-and-reel packaging (1,000 pcs/reel). This distinguishes it from non-qualified variants like 6A40G, ensuring traceability to automotive-grade stress testing and process controls.
