Taiwan Semiconductor Corporation 2A06G B0G

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 (VRRM), 2 A average forward current (IF), and 70 A non-repetitive surge current (IFSM), used in DC-DC converters and switching-mode power supplies.

For engineers reviewing the 2A06G datasheet, 2A06G pinout, 2A06G application, or 2A06G equivalent, key selection criteria include VRRM = 800 V, VF ≤ 1.0 V at IF = 2 A and TJ = 25°C, IR ≤ 5 µA at VR = 800 V and TJ = 25°C, RθJA = 60 °C/W, and DO-204AC mechanical compatibility with through-hole PCB assembly.

Technical Context

This device is a single-die, glass-passivated, standard recovery rectifier optimized for general-purpose AC/DC and DC/DC conversion. It features low forward voltage drop (VF ≤ 1.0 V), high surge robustness (IFSM = 70 A), and thermal resistance RθJL = 25 °C/W for efficient heat transfer to the lead frame.

Designed for operation across -55°C to +150°C junction temperature range, it supports reliable performance in industrial and automotive-grade applications where AEC-Q101 qualification is available in variant 2A06GH. Its 15 pF junction capacitance at 1 MHz and 4 V reverse bias enables stable behavior in moderate-frequency switching circuits.

2A06G is available at Aetrix Electronics and suitable for DC-DC converters, switching mode inverters, and general-purpose rectification requiring stable component supply across industrial, automotive, and consumer electronics programs.

Supply support for 2A06G includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving global industrial, automotive, and consumer markets since 1979.

The 2A01G–2A07G series is part of TSC's standard rectifier product line, engineered for cost-effective, high-reliability AC/DC and DC/DC power conversion in space- and thermal-constrained applications.

FAQ

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

The 2A06G has a VRRM rating of 800 V, meaning it can block up to 800 V of reverse voltage continuously without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version I2105) and applies under standard test conditions (TA = 25°C). The 2A06G is designed for use in 600–800 V DC bus applications where this margin ensures robust operation during line transients and voltage spikes.

What is the forward voltage (VF) specification for the 2A06G at rated current?

The 2A06G exhibits a maximum forward voltage of 1.0 V at IF = 2 A and TJ = 25°C, per the Electrical Specifications table. This low VF contributes to reduced conduction losses and improved thermal performance compared to higher-VF alternatives. The 2A06G maintains this specification across its designated voltage family (2A03G–2A07G), distinguishing it from lower-voltage variants like 2A01G/2A02G (VF ≤ 1.1 V).

Is the 2A06G RoHS and halogen-free compliant?

Yes, the 2A06G is RoHS compliant and halogen-free in accordance with IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and its pure tin-plated leads are solderable per J-STD-002. These compliance attributes are explicitly stated in the FEATURES section of the TSC datasheet and verified in the Mechanical Data and Ordering Information pages for the 2A01G–2A07G family.

Does the 2A06G have AEC-Q101 qualification?

The base 2A06G is not AEC-Q101 qualified; however, the variant 2A06GH is explicitly listed as AEC-Q101 qualified in the Ordering Information table. The "H" suffix denotes qualification per AEC-Q101 stress test requirements. For automotive applications requiring qualification, 2A06GH must be specified-2A06G itself carries no AEC-Q101 certification.

What is the thermal resistance from junction to ambient (RθJA) for the 2A06G?

The 2A06G has a typical junction-to-ambient thermal resistance (RθJA) of 60 °C/W, as published in the Thermal Performance section of the TSC datasheet. This value assumes standard JEDEC test conditions (single device on FR-4 board, 1 in² copper pad). It serves as a critical parameter for estimating junction temperature rise under load and informs heatsinking decisions in thermally constrained layouts.
