Product details
Overview
2A05G from Taiwan Semiconductor is a standard silicon rectifier diode in DO-204AC (DO-15) package, rated for 600 V repetitive peak reverse voltage (VRRM), 2 A average forward current (IF), and 70 A non-repetitive surge current (IFSM). It features low forward voltage (VF ≤ 1.0 V at IF = 2 A, TJ = 25°C), glass passivated junction, and AEC-Q101 qualification option - used in DC-DC converters and switching-mode inverters.
For engineers reviewing the 2A05G datasheet, 2A05G pinout, 2A05G application, or 2A05G equivalent, key selection criteria include VRRM = 600 V, IF = 2 A, VF ≤ 1.0 V, IFSM = 70 A, and DO-204AC mechanical compatibility with through-hole PCB assembly and automated tape-and-reel handling.
Technical Context
The 2A05G is a single-die, general-purpose axial-lead rectifier optimized for medium-voltage, medium-current switching power supplies. Its glass-passivated junction ensures stable reverse leakage (IR ≤ 5 µA at VR = 600 V, TJ = 25°C) and robust thermal performance (RθJL = 25°C/W).
Designed for operation up to TJ = 150°C, it delivers low conduction loss (VF ≤ 1.0 V) and high surge tolerance (IFSM = 70 A, 8.3 ms half-sine), making it suitable for transient-heavy industrial and automotive auxiliary power stages where reliability under thermal cycling is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum reverse voltage the device blocks continuously without breakdown. |
| IF | 2 A - Continuous average forward current rating at TA = 75°C with adequate heatsinking. |
| IFSM | 70 A - Peak non-repetitive surge current capability for 8.3 ms half-sine waveform. |
| VF | ≤1.0 V - Forward voltage drop at IF = 2 A and TJ = 25°C; determines conduction loss in power stage. |
| IR | ≤5 µA - Reverse leakage current at VR = 600 V and TJ = 25°C; impacts standby power in high-impedance circuits. |
| RθJL | 25 °C/W - Junction-to-lead thermal resistance; enables direct solder-point temperature estimation in layout. |
Pinout & Package
Package: DO-204AC (DO-15), axial-lead, epoxy-molded, cathode indicated by band. Leads are pure tin-plated, J-STD-002 solderable, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of AC input or transformer secondary; must withstand surge during turn-on. |
| Cathode | Forward current exit point | Marked with band; connects to output capacitor or load return; carries full IF and handles reverse blocking stress. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable IR performance and long-term reliability under humidity and thermal stress per AEC-Q101 requirements. |
| Low VF (≤1.0 V) | Reduces conduction losses in 2 A continuous applications, improving efficiency in compact DC-DC modules. |
| High IFSM (70 A) | Withstands inrush and fault currents in offline SMPS without catastrophic failure. |
| DO-204AC mechanical standardization | Ensures compatibility with legacy through-hole tooling, wave soldering profiles, and JEDEC-compliant board cutouts. |
Applications
| DC-DC Converter Primary Rectification | Switching Inverter Output Stage |
|---|---|
Use Scenario: Rectifying high-frequency transformer output in isolated 24–48 V input DC-DC converters for telecom and industrial control. IC Role / Device Role / Timing Role: Power rectifier converting AC-like switching waveform to unidirectional DC bus. Use Value: Low VF minimizes heat generation at 2 A load; 600 V VRRM safely handles reflected spikes from transformer leakage inductance. | Use Scenario: Output freewheeling/commutation path in three-phase motor drive inverters operating up to 400 V DC bus. IC Role / Device Role / Timing Role: Freewheeling diode clamping inductive kickback during IGBT/MOSFET turn-off. Use Value: 70 A IFSM absorbs short-circuit energy; glass passivation ensures stability across wide temperature range (−55°C to +150°C). |
| Automotive Auxiliary Power Supply | Industrial AC-DC Adapter |
Use Scenario: Input rectification in 12 V/24 V vehicle-mounted power modules supplying infotainment or ADAS sensors. IC Role / Device Role / Timing Role: Bridge or single-diode rectifier in low-power offline SMPS meeting AEC-Q101 stress requirements. Use Value: Optional AEC-Q101 qualification supports automotive qualification flow; DO-15 package fits constrained under-hood space. | Use Scenario: General-purpose rectification in universal-input (85–265 VAC) AC-DC adapters for industrial instrumentation.

Use Value: RoHS- and halogen-free compliance meets global environmental regulations; 150°C TJ max supports sealed enclosure operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | VRRM = 600 V, IF = 2 A, VF = 1.15 V (typ), DO-204AC, no AEC-Q101 option | Higher VF increases conduction loss; lacks automotive qualification path | Preferred where cost sensitivity outweighs VF and qualification needs |
| ON Semi MUR260 | VRRM = 600 V, IF = 2 A, VF = 0.95 V (typ), ultrafast recovery (trr = 50 ns), DO-204AC | Faster recovery reduces switching loss in high-frequency (>100 kHz) designs but adds cost | Chosen when EMI or efficiency at >50 kHz is critical; not needed for 20–50 kHz SMPS |
Compared with STTH2R06 and MUR260, the 2A05G offers balanced VF (≤1.0 V), proven surge robustness (70 A), and optional AEC-Q101 qualification - making it optimal for cost-sensitive, thermally demanding, or automotive-adjacent 600 V rectification where ultrafast recovery is unnecessary.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the 2A05G?
The 2A05G has a VRRM rating of 600 V, meaning it can reliably block up to 600 V of reverse voltage in continuous operation without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version I2105) and is specific to the 2A05G variant within the 2A01G–2A07G family. Exceeding this voltage risks irreversible avalanche failure.
Is the 2A05G AEC-Q101 qualified?
The base 2A05G is not automatically AEC-Q101 qualified; qualification requires the "H" suffix (i.e., 2A05GH). Per TSC's Ordering Information, only variants marked with "H" undergo AEC-Q101 stress testing. The 2A05G itself shares the same die and construction but lacks formal automotive qualification documentation unless ordered as 2A05GH.
What is the forward voltage (VF) of the 2A05G at 2 A and 25°C?
The 2A05G exhibits a maximum forward voltage of 1.0 V at IF = 2 A and TJ = 25°C, as specified in the Electrical Specifications table (Version I2105). This value applies to the 2A03G–2A07G group, including 2A05G. At higher junction temperatures, VF decreases slightly, but design margin should be based on the 1.0 V max limit.
What package type does the 2A05G use, and is it lead-free?
The 2A05G uses the DO-204AC (DO-15) axial-leaded package with pure tin-plated leads compliant with J-STD-002 solderability standards. It is RoHS-compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the device weighs approximately 0.400 g.
How does the 2A05G compare to the 2A04G in terms of voltage rating and application suitability?
The 2A04G is rated for 400 V VRRM, while the 2A05G is rated for 600 V VRRM - a 200 V higher blocking capability. Both share identical IF = 2 A, IFSM = 70 A, and VF ≤ 1.0 V specs. Use 2A05G where reflected transients or line surges exceed 400 V, such as in 230 VAC-fed SMPS with poor input filtering or industrial motor drives with high inductive kickback.
