Product details
Overview
2A06G-T from Taiwan Semiconductor is a 2 A, 800 V standard silicon rectifier diode in DO-204AC (DO-15) package, featuring 1.0 V max forward voltage at 2 A and 70 A non-repetitive surge capability, used in switching mode power supplies and DC-DC converters.
For engineers reviewing the 2A06G-T datasheet, 2A06G-T pinout, 2A06G-T application, or 2A06G-T equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (RθJL = 25°C/W), junction capacitance (15 pF), and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
This single-die standard rectifier operates with glass-passivated junction for reliability under high surge stress and elevated ambient temperatures up to +150°C. Its low VF and low power loss support high-efficiency operation in continuous conduction mode.
The device exhibits stable reverse leakage (≤5 µA at 25°C, ≤100 µA at 125°C) and predictable junction capacitance (15 pF at 4 V, 1 MHz), enabling consistent performance in high-frequency switching topologies such as flyback and forward converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - maximum repetitive reverse voltage; defines safe blocking range in 600–800 V bus applications |
| IF | 2 A - average forward current; supports continuous output in mid-power SMPS designs |
| IFSM | 70 A - 8.3 ms half-sine surge rating; handles inrush and transient overloads without failure |
| VF (max) | 1.0 V @ 2 A, 25°C - low conduction loss reduces thermal load and improves efficiency |
| RθJL | 25 °C/W - junction-to-lead thermal resistance enables direct PCB copper pour heat sinking |
| CJ | 15 pF @ 4 V, 1 MHz - low junction capacitance minimizes switching noise and EMI in high-frequency operation |
| TJ max | +150°C - extended junction temperature rating allows operation in compact, thermally constrained enclosures |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, glass-passivated silicon die, cathode indicated by band. Leads are pure tin-plated, J-STD-002 solderable, UL 94V-0 molded compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/primary side; must withstand full surge current and reverse recovery stress |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; ties to output/secondary ground reference; carries full load current continuously |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same 2 A / 600 V rating; VF = 1.15 V (max); RθJL = 30°C/W; TO-220AC package | Higher thermal resistance and VF increase conduction loss; requires heatsink above 1.2 A continuous | Prefer 2A06G-T for DO-15 footprint, lower VF, and better thermal coupling to PCB |
| ON Semi MUR260 | 2 A / 600 V ultrafast recovery (trr = 50 ns); VF = 1.25 V; DO-15 package | Ultrafast recovery reduces switching loss but increases conduction loss; suited for >100 kHz topologies | Choose 2A06G-T where cost, VF, and surge robustness outweigh need for fast recovery |
Compared with STTH2R06 and MUR260, the 2A06G-T delivers superior conduction efficiency in DO-15 form factor, lower thermal resistance for PCB-conducted cooling, and higher surge margin-making it optimal for cost-sensitive, thermally constrained 50–100 kHz SMPS designs.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the 2A06G-T?
The 2A06G-T has a maximum repetitive peak reverse voltage (VRRM) of 800 V, as confirmed in the Absolute Maximum Ratings table on page 2 of the official TSC datasheet revision B2105. This rating defines the highest reverse voltage the device can block repeatedly without breakdown under normal operating conditions, making it suitable for 600–800 V DC bus applications. The 2A06G-T is part of a standardized family where "06" explicitly denotes the 800 V grade.
What is the forward voltage (VF) specification for the 2A06G-T at rated current?
The 2A06G-T has a maximum forward voltage (VF) of 1.0 V at 2 A forward current and 25°C junction temperature, per the Electrical Specifications table (page 2). This value applies to the 2A03G-T through 2A07G-T variants and reflects low conduction loss optimized for efficiency-critical power stages. Pulse test conditions (PW = 0.3 ms) ensure measurement accuracy under realistic switching conditions.
Does the 2A06G-T have RoHS and halogen-free compliance?
Yes, the 2A06G-T is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section of the official datasheet. The molding compound meets UL 94V-0 flammability rating, and the pure tin-plated leads satisfy J-STD-002 solderability requirements. These certifications are verified for the entire 2A01G-T to 2A07G-T family, including the 2A06G-T.
What is the surge current rating (IFSM) of the 2A06G-T and how is it tested?
The 2A06G-T has a non-repetitive peak forward surge current (IFSM) rating of 70 A, tested using an 8.3 ms single half-sine wave superimposed on rated load, per JEDEC standards. This rating is identical across all variants in the 2A01G-T to 2A07G-T series and ensures robustness against line transients, startup inrush, and short-circuit events in power supply front ends.
What package type and marking code does the 2A06G-T use?
The 2A06G-T uses the DO-204AC (DO-15) axial package with glass-passivated chip junction and cathode band polarity indication. Its marking code is "2A06G", printed on the body per the Marking Diagram on page 4 of the datasheet. The "-T" suffix denotes tape-and-reel packaging (3,500 units per reel), and "G" confirms green (halogen-free) compound.
