Product details
Overview
6A05G from Taiwan Semiconductor is a 6 A, 50 V glass-passivated standard rectifier diode in R-6 package, featuring 1.1 V forward voltage at 6 A and 250 A surge capability, used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the 6A05G datasheet, 6A05G pinout, 6A05G application, or 6A05G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), forward current rating (6 A), thermal resistance (35 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification availability.
Technical Context
This single-die standard rectifier operates with a glass-passivated PN junction for enhanced reliability and moisture resistance. Its R-6 axial package supports high surge current (250 A, 8.3 ms half-sine) and low conduction loss due to VF ≤ 1.1 V at rated IF.
The device exhibits TJ-dependent reverse leakage (10 µA at 25 °C, 100 µA at 125 °C) and 60 pF junction capacitance at 1 MHz / 4 V, making it suitable for medium-frequency switching applications up to several hundred kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Rated Forward Current) | 6 A - continuous DC current handling capacity under specified thermal conditions |
| VRRM (Repetitive Peak Reverse Voltage) | 50 V - maximum allowable reverse voltage before breakdown, defines blocking capability in rectification |
| IFSM (Surge Forward Current) | 250 A - short-duration (8.3 ms) overload tolerance, critical for inrush and transient immunity |
| VF (Forward Voltage @ 6 A, 25 °C) | 1.1 V - conduction loss contributor; determines power dissipation (6.6 W at full load) |
| RθJA (Junction-to-Ambient) | 35 °C/W - thermal resistance without heatsink; sets max ambient temperature for safe 6 A operation |
| TJ (Operating Junction Temp) | –55 to +150 °C - wide temperature envelope enabling use in automotive under-hood and industrial environments |
| CJ (Junction Capacitance) | 60 pF @ 1 MHz, 4 V - affects high-frequency switching noise and recovery behavior |
Pinout & Package
Package: R-6 axial leaded case per JEDEC TO-220AC variant; molded compound meets UL 94V-0; pure tin-plated leads; cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Positive input terminal for forward conduction | Connected to AC source or transformer secondary during positive half-cycle |
| Cathode (Lead 2) | Output/return terminal; marked with band | Delivers rectified DC output; polarity must be observed in PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Prevents moisture ingress and surface contamination, improving long-term reliability in humid environments |
| AEC-Q101 qualified version available | Validated for automotive-grade stress testing (HTOL, TC, HAST), supporting under-hood deployment |
| Low VF (1.1 V @ 6 A) | Reduces conduction losses by ~15% vs. comparable 1.3 V diodes, lowering thermal load in compact designs |
| High IFSM (250 A) | Withstands repeated cold-start surges in SMPS without degradation, extending service life |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally regulated markets |
Applications
| DC-DC Converter | Switching Mode Inverter |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 5–24 V DC output. IC Role / Device Role / Timing Role: Standard rectifier converting high-frequency AC from transformer secondary into unidirectional DC. Use Value: 1.1 V VF minimizes power loss at 6 A output, while 50 V VRRM provides sufficient margin over 36 V nominal bus. | Use Scenario: Output stage rectification in 12 V–48 V input inverters for UPS or solar micro-inverters. IC Role / Device Role / Timing Role: Unidirectional current path for AC waveform synthesis; handles bidirectional switching transients. Use Value: 250 A IFSM absorbs inverter shoot-through spikes; R-6 package enables through-hole mounting on high-current PCBs. |
| Automotive Power Supply | Industrial AC/DC Adapter |
Use Scenario: Input rectification in 12 V battery-fed auxiliary power modules (e.g., infotainment, ADAS sensors). IC Role / Device Role / Timing Role: Primary AC-to-DC conversion stage; withstands load dump and cold-crank transients. Use Value: AEC-Q101-qualified variants ensure compliance with automotive reliability standards; –55 to +150 °C TJ range covers engine bay extremes. | Use Scenario: General-purpose rectification in wall-mounted AC/DC adapters for industrial control panels and PLC I/O modules. IC Role / Device Role / Timing Role: Bridge or single-diode rectifier in linear or quasi-resonant topologies. Use Value: UL 94V-0 molding compound and halogen-free construction meet industrial safety and environmental requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06D (STMicroelectronics) | 6 A, 60 V, VF = 1.05 V @ 6 A, TO-220AC package, no AEC-Q101 option | Higher VRRM margin (60 V), but lacks automotive qualification and uses different footprint | Select when higher reverse voltage margin is required and AEC-Q101 is not mandatory |
| ON Semi MUR620CT (dual common-cathode) | 6 A per diode, 200 V, VF = 0.97 V, TO-220AB package, fast recovery (trr = 35 ns) | Fast-recovery architecture reduces switching loss; dual configuration enables full-wave rectification | Select for higher-frequency SMPS (>100 kHz) where reverse recovery matters more than cost or size |
Compared with STTH6L06D and MUR620CT, the 6A05G offers lower cost and proven ruggedness in 50 V-class applications, with AEC-Q101 availability for automotive use-though it lacks fast-recovery performance or extended voltage headroom.

FAQ
What is the maximum junction temperature rating for the 6A05G?
The 6A05G has a maximum junction temperature (TJ) of +150 °C and a minimum of –55 °C. This wide operating range allows reliable use in under-hood automotive environments and high-ambient industrial enclosures. Thermal design must ensure junction temperature stays within this limit under full 6 A load, considering its 35 °C/W RθJA.
Does the 6A05G have AEC-Q101 qualification?
The base 6A05G is not AEC-Q101 qualified, but Taiwan Semiconductor offers an AEC-Q101-qualified version identified as 6A05GH. The "H" suffix denotes automotive qualification per AEC-Q101 Rev D, including stress testing for HTOL, TC, and HAST. Always verify the full ordering code when selecting for automotive applications.
What is the forward voltage drop of the 6A05G at rated current?
The 6A05G exhibits a typical forward voltage (VF) of 1.1 V at 6 A and 25 °C, measured under pulsed conditions (PW = 0.3 ms). At elevated junction temperatures, VF decreases slightly, but system-level thermal design must account for worst-case conduction loss (6.6 W at 25 °C).
What package type does the 6A05G use, and what are its mechanical features?
6A05G uses the R-6 axial-leaded package: UL 94V-0 rated epoxy molding compound, pure tin-plated leads compliant with J-STD-002, and cathode polarity marked by a band. It weighs approximately 1.65 g and conforms to JEDEC TO-220AC outline dimensions, enabling compatibility with standard through-hole assembly processes.
How does the 6A05G compare to higher-voltage variants like 6A100G?
The 6A05G is electrically identical to other members of the 6A05G–6A100G family except for VRRM: it is rated for 50 V versus 1000 V for 6A100G. All share the same IF (6 A), IFSM (250 A), RθJA (35 °C/W), and R-6 package. Voltage selection must match circuit blocking requirements-using 6A05G in >50 V reverse-bias applications risks catastrophic failure.
