Product details

Overview

2A06G from Taiwan Semiconductor is a standard silicon rectifier diode in DO-204AC (DO-15) package, rated for 800 V repetitive peak reverse voltage (V_RRM), 2 A average forward current (I_F), and 70 A non-repetitive surge current (I_FSM). It delivers low forward voltage drop (1.0 V at 2 A, 25°C) and supports DC-DC converters and switching-mode inverters requiring robust, RoHS-compliant power rectification.

For engineers reviewing the 2A06G datasheet, 2A06G pinout, 2A06G application, or 2A06G equivalent, key selection criteria include its 800 V V_RRM, 1.0 V V_F at rated current, DO-15 mechanical compatibility, AEC-Q101 qualification option (2A06GH), and thermal resistance of 25 °C/W (junction-to-lead).

Technical Context

The 2A06G is a single-die, glass-passivated, planar junction standard rectifier optimized for high-efficiency AC/DC and DC/DC conversion. Its 800 V V_RRM and 70 A I_FSM enable reliable operation under transient overvoltage and surge conditions typical in industrial power supplies and automotive auxiliary systems.

Thermal performance is defined by R_θJL = 25 °C/W and R_θJA = 60 °C/W, supporting conduction-cooled mounting on PCBs without heatsinks up to ~1.2 W dissipation at ambient. The device operates across –55°C to +150°C junction temperature range and features pure tin-plated leads compliant with J-STD-002 solderability.

Key Specifications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R08	V_RRM = 800 V, V_F = 1.15 V @ 2 A, R_θJL = 20 °C/W, TO-220AC package	Higher thermal conductivity but larger footprint; requires heatsink above ~1.5 W	Select when higher surge margin or forced-air cooling is available and DO-15 size constraint does not apply
ON Semi MUR280	V_RRM = 800 V, V_F = 1.1 V @ 2 A, ultrafast recovery (t_rr = 75 ns), DO-41 package	Lower reverse recovery charge but smaller leadframe; limited I_FSM = 50 A	Select when switching frequency exceeds 100 kHz and EMI reduction is critical; avoid in high-surge industrial mains input

Compared with STTH2R08 and MUR280, the 2A06G offers optimal balance of DO-15 form factor, 70 A surge rating, and 1.0 V forward drop-making it preferred for space-constrained, high-reliability 50–100 kHz SMPS where thermal budget is moderate and surge immunity is essential.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the 2A06G?

The 2A06G has a V_RRM of 800 V, as confirmed in the Absolute Maximum Ratings table across all versions of the datasheet. This value is specific to the 2A06G marking code and distinguishes it from adjacent family members (e.g., 2A05G = 600 V, 2A07G = 1000 V). The 2A06G must not be subjected to reverse voltages exceeding this rating to ensure reliable long-term operation.

Is the 2A06G RoHS and halogen-free compliant?

Yes, the 2A06G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the official Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0, and terminals are pure tin plated-fully satisfying environmental compliance requirements for commercial and automotive electronics.

Does the 2A06G have AEC-Q101 qualification?

The base 2A06G is not AEC-Q101 qualified; however, the variant 2A06GH is explicitly listed in the Ordering Information as AEC-Q101 qualified. This distinction is critical: only parts ordered with the "H" suffix undergo the full stress-test sequence per AEC-Q101, including temperature cycling, high-temperature reverse bias, and mechanical shock testing.

What is the forward voltage (V_F) of the 2A06G at 2 A and 25°C?

The 2A06G exhibits a maximum forward voltage of 1.0 V at I_F = 2 A and T_J = 25°C, as specified in the Electrical Specifications table for the 2A03G–2A07G group. This value is measured under pulsed conditions (PW = 0.3 ms) and represents the upper limit-typical units measure ~0.92 V, contributing to lower conduction losses than earlier-generation rectifiers.

What package type does the 2A06G use, and what are its key mechanical attributes?

The 2A06G uses the DO-204AC (DO-15) package: axial-leaded, molded plastic case with cathode band marking. Key attributes include UL 94V-0 flammability rating, pure tin-plated leads (J-STD-002 compliant), JESD201 Class 2 whisker resistance, and approximate weight of 0.400 g. Dimensions conform to standard DO-15 outline drawings in the Package Outline Dimensions section.
