Taiwan Semiconductor Corporation 2A01G R0G

Overview

2A01G from Taiwan Semiconductor is a 2 A, 50 V standard glass-passivated silicon rectifier diode in DO-204AC (DO-15) package, featuring 1.1 V max forward voltage at 2 A and 70 A non-repetitive surge current capability, used in DC-DC converters and switching-mode power supplies.

For engineers reviewing the 2A01G datasheet, 2A01G pinout, 2A01G application, or 2A01G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), thermal resistance (R_θJL = 25 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification availability for automotive-grade variants.

Technical Context

This single-die standard rectifier operates with a glass-passivated PN junction to ensure stable reverse blocking and low leakage-IR ≤ 5 µA at 25 °C and ≤ 100 µA at 125 °C-enabling reliable operation in high-temperature industrial and automotive environments.

Its DO-204AC (DO-15) axial-leaded package supports manual and automated through-hole assembly, with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance, and UL 94V-0 molding compound.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the 2A01G?

The 2A01G has a maximum repetitive peak reverse voltage (V_RRM) of 50 V. This rating defines the highest reverse-biased voltage the diode can block repeatedly without avalanche breakdown. It is validated per JEDEC standards and applies across the full operating junction temperature range (–55 to +150 °C). The 2A01G is part of the 2A01G–2A07G family, where V_RRM scales from 50 V to 1000 V across variants.

Does the 2A01G have AEC-Q101 qualification?

The base 2A01G is not AEC-Q101 qualified; however, the variant 2A01GH is explicitly qualified per AEC-Q101 Rev D for automotive applications. This qualification includes stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life. The 2A01G datasheet confirms "AEC-Q101 qualified available" as a family-level option, and distributor documentation validates 2A01GH as the qualified version.

What is the forward voltage (V_F) specification for the 2A01G at rated current?

The 2A01G has a maximum forward voltage (V_F) of 1.1 V at I_F = 2 A and T_J = 25 °C, measured under pulsed conditions (PW = 0.3 ms). This value reflects conduction loss under typical operating conditions and remains stable across the device's thermal operating range. The 2A01G datasheet specifies this parameter separately from higher-voltage family members (e.g., 2A03G–2A07G specify 1.0 V max), confirming its optimized low-V_F design for 50 V applications.

What package type does the 2A01G use, and what are its mechanical features?

The 2A01G uses the DO-204AC (DO-15) axial-leaded package. Key mechanical features include UL 94V-0 flammability-rated epoxy molding, pure tin-plated leads compliant with J-STD-002 solderability, JESD201 Class 2 whisker resistance, and cathode polarity indicated by a visible band. Its weight is approximately 0.400 g, and it supports tape-and-reel (3,500 pcs) or ammo box (1,500 pcs) packaging formats.

How does the 2A01G compare to the 1N4001 in terms of electrical performance and qualification?

The 2A01G matches the 1N4001's 50 V V_RRM and 1.1 V V_F max but offers tighter reverse leakage (≤5 µA at 25 °C vs. ≤50 µA for 1N4001), AEC-Q101-qualified variant (2A01GH), and halogen-free construction per IEC 61249-2-21. Both use DO-204AC packages, but the 2A01G provides enhanced reliability for automotive and industrial deployments where leakage, material compliance, and qualification matter.
