Taiwan Semiconductor Corporation 2A06GH

Overview

2A06GH from Taiwan Semiconductor is an AEC-Q101-qualified 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 automotive-grade DC-DC converters and switching inverters.

For engineers reviewing the 2A06GH datasheet, 2A06GH pinout, 2A06GH application, or 2A06GH equivalent, key selection criteria include its 800 V VRRM rating, 1.0 V max forward voltage at 2 A/25°C, AEC-Q101 qualification, DO-15 package thermal resistance (RθJL = 25°C/W), and suitability for high-surge industrial power supplies.

Technical Context

This single-die standard rectifier operates with glass-passivated junction for reliability under thermal cycling and humidity stress. Its low VF (≤1.0 V @ 2 A, 25°C) and high IFSM (70 A, 8.3 ms half-sine) support efficient energy conversion in compact switching topologies.

The device features a cathode-banded polarity indicator, pure tin-plated leads compliant with J-STD-002, and UL 94V-0 molding compound. Junction temperature range is –55°C to +150°C, with RθJA = 60°C/W and RθJC = 22°C/W enabling stable operation in convection-cooled automotive and industrial enclosures.

FAQ

What is the maximum repetitive peak reverse voltage (VRRM) of the 2A06GH?

The 2A06GH has a VRRM rating of 800 V, confirmed in the Absolute Maximum Ratings table across all versions of the 2A01G–2A07G datasheet (Version I2105). This value is fixed for the "06" variant and defines the highest reverse voltage the device can block repeatedly without breakdown. It is critical for selecting appropriate safety margins in 400–600 VDC bus applications. The 2A06GH maintains this rating across its full operating temperature range.

Is the 2A06GH AEC-Q101 qualified, and what does the "H" suffix indicate?

Yes, the "H" suffix in 2A06GH explicitly denotes AEC-Q101 qualification per the Ordering Information section of the datasheet. This means the 2A06GH has undergone stress testing-including high-temperature operating life (HTOL), temperature cycling (TC), and biased highly accelerated stress test (BHAST)-to validate reliability for automotive power electronics. The 2A06GH is not just a standard-grade part with optional qualification; the "H" version is manufactured and tested to meet the full AEC-Q101 standard.

What is the forward voltage (VF) specification for the 2A06GH at rated current?

The 2A06GH has a maximum forward voltage of 1.0 V at IF = 2 A and TJ = 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 worst-case conduction loss. At elevated temperatures (e.g., 125°C), VF decreases slightly, but design margin should be based on the 1.0 V max value. The 2A06GH's VF is lower than many competing 800 V rectifiers, directly improving system efficiency.

Does the 2A06GH have a defined junction-to-lead thermal resistance (RθJL)?

Yes, the 2A06GH has a typical junction-to-lead thermal resistance (RθJL) of 25°C/W, listed in the Thermal Performance section of the datasheet. This parameter is measured under standardized conditions and enables accurate thermal modeling when the leads are soldered to a large copper area acting as a heat path. Unlike RθJA (60°C/W), RθJL reflects performance with effective PCB heatsinking-making it essential for predicting die temperature in real-world automotive and industrial layouts.

What packaging options are available for the 2A06GH?

The 2A06GH is offered in DO-204AC (DO-15) package with two standard packing formats: 3,500 units per tape-and-reel (ordering code 2A06GH) and 1,500 units per ammo box (ordering code 2A06GHA0G). Both use the same DO-15 mechanical outline and green molding compound. No alternate packages (e.g., SMD or TO-220) are listed for the 2A06GH in the official documentation; it is exclusively an axial-leaded device.
