Taiwan Semiconductor Corporation 2A07G

Overview

2A07G from Taiwan Semiconductor is a 1000V, 2A standard glass-passivated silicon rectifier diode in DO-204AC (DO-15) package, featuring 1.0V max forward voltage at 2A and 5µA max reverse leakage at 25°C, used in high-voltage DC-DC converters and switching inverters.

For engineers reviewing the 2A07G datasheet, 2A07G pinout, 2A07G application, or 2A07G equivalent, key selection criteria include peak reverse voltage rating (1000V), surge current capability (70A), thermal resistance (R_θJL = 25°C/W), and AEC-Q101 qualification availability for automotive-grade reliability.

Technical Context

This device is a single-die, axial-leaded standard rectifier optimized for high-voltage, medium-current power conversion. Its glass-passivated junction ensures stable performance under thermal cycling and humidity stress, while the DO-204AC package supports through-hole mounting with UL 94V-0 molding compound and pure tin-plated leads compliant with J-STD-002.

The 2A07G operates across -55°C to +150°C junction temperature range, delivers 70A non-repetitive surge current (8.3ms half-sine), and exhibits 15pF junction capacitance at 1MHz/4V - enabling use in high-frequency switching topologies where low stored charge and fast recovery are critical.

FAQ

What is the maximum repetitive peak reverse voltage rating for the 2A07G?

The 2A07G has a maximum repetitive peak reverse voltage (V_RRM) of 1000 V. This rating defines the highest reverse-biased voltage the diode can block continuously without avalanche breakdown. It is confirmed in the Absolute Maximum Ratings table across all versions of the 2A01G–2A07G series, with 2A07G specifically designated for the 1000V variant. Designers must ensure system-level transient voltages remain within this limit, including safety margins.

Does the 2A07G have AEC-Q101 qualification?

The base 2A07G is not AEC-Q101 qualified, but the AEC-Q101-compliant version is available as 2A07GH - indicated by the "H" suffix in the ordering code. This variant undergoes stress testing per AEC-Q101 Rev D, including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. The 2A07G itself shares identical electrical and thermal specs but lacks the automotive qualification documentation and traceability.

What is the forward voltage drop of the 2A07G at rated current?

The 2A07G exhibits a maximum forward voltage (V_F) of 1.0 V at 2 A forward current and 25°C junction temperature. This value is specified in the Electrical Specifications table for the 2A03G–2A07G group. At elevated temperatures (e.g., 125°C), V_F decreases slightly, but design calculations should use the 1.0 V max value to ensure worst-case conduction loss budgeting in the 2A07G application.

What package type does the 2A07G use, and what are its mechanical highlights?

The 2A07G uses the DO-204AC (DO-15) axial-leaded package. Key mechanical features include UL 94V-0 flammability-rated epoxy molding compound, pure tin-plated leads compliant with J-STD-002 solderability, cathode band polarity marking, and JESD 201 Class 2 whisker resistance. Its weight is approximately 0.400 g, and it is supplied in tape-and-reel (3,500 pcs) or ammo box (1,500 pcs) formats.

How does the 2A07G compare thermally to other DO-15 rectifiers?

The 2A07G has a junction-to-lead thermal resistance (R_θJL) of 25°C/W, which is competitive among DO-15 rectifiers. This value enables effective heat transfer from the die to the PCB copper via the leads, supporting 2A continuous operation without forced air or heatsinks in well-designed layouts. Its R_θJA is 60°C/W, meaning ambient-limited derating begins above ~75°C unless additional copper area is used - a key differentiator from higher-R_θJL alternatives like some legacy 1N4007 variants.
