Product details

Overview

2A01G from Taiwan Semiconductor is a 2 A, 50 V repetitive peak reverse voltage standard rectifier diode in DO-204AC (DO-15) package, featuring 1.1 V forward voltage at 2 A and 70 A surge 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 VRRM=50 V, IF=2 A, VF=1.1 V @ 2 A, IFSM=70 A, and DO-204AC mechanical compatibility for through-hole power rectification.

Technical Context

This single-die standard rectifier operates with glass passivated junction for reliability and low leakage, supporting continuous forward conduction up to 150 °C junction temperature and delivering high efficiency via low forward voltage drop and low power loss.

Thermal performance is defined by R_θJL = 25 °C/W and R_θJA = 60 °C/W, enabling stable operation under moderate ambient conditions without forced cooling in typical industrial and consumer power conversion designs.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	50 V - maximum non-repetitive reverse voltage the device blocks reliably
IF	2 A - continuous average forward current rating at TA = 25 °C
VF	1.1 V @ 2 A, TJ = 25 °C - forward voltage drop determining conduction loss in power stage
IFSM	70 A - peak surge current handling for 8.3 ms half-sine, critical for startup/inrush immunity
TJ max	150 °C - maximum allowable junction temperature defining thermal derating envelope
R_θJL	25 °C/W - junction-to-lead thermal resistance, guiding heatsinking and PCB copper design
CJ	15 pF @ 1 MHz, VR = 4 V - junction capacitance affecting high-frequency switching behavior

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4001G	VRRM = 50 V, IF = 1 A, VF ≈ 1.1 V @ 1 A - lower current rating than 2A01G	Suitable only for ≤1 A loads; insufficient for sustained 2 A operation	Select 2A01G when full 2 A continuous current and 70 A surge margin are required
RS2M	VRRM = 1000 V, IF = 2 A, VF = 1.3 V @ 2 A - higher VRRM but higher VF	Better for high-voltage isolation; less efficient at 50 V systems due to increased conduction loss	Choose 2A01G for optimized efficiency in ≤50 V applications where lower VF directly improves thermal margin

Compared with 1N4001G and RS2M, the 2A01G provides the optimal balance of 2 A current capacity, 50 V blocking, and lowest VF in its voltage class-enabling smaller thermal design and higher power density in cost-sensitive 50 V rectification tasks.

FAQ

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

The 2A01G has a VRRM rating of 50 V, meaning it can reliably block up to 50 V of reverse voltage in repetitive operation. This value is fixed for the 2A01G variant and distinguishes it from higher-voltage members like 2A02G (100 V) and 2A07G (1000 V) in the same family. Exceeding 50 V risks avalanche breakdown and permanent damage to the 2A01G.

What is the forward voltage drop (VF) of the 2A01G at rated current?

The 2A01G exhibits a typical forward voltage drop of 1.1 V at 2 A and 25 °C junction temperature. This value is measured under pulsed conditions (PW = 0.3 ms) and represents the conduction loss during normal operation. At elevated temperatures or higher currents, VF may increase slightly, but remains within specification limits across the full operating range of the 2A01G.

Is the 2A01G RoHS and halogen-free compliant?

Yes, the 2A01G is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and its pure tin-plated leads satisfy J-STD-002 solderability requirements. These compliance attributes are confirmed for the 2A01G in the official Taiwan Semiconductor documentation and apply to all standard-grade units-not just AEC-Q101 qualified variants.

What package type does the 2A01G use, and how is polarity marked?

The 2A01G uses the DO-204AC (DO-15) axial-leaded package. Polarity is clearly indicated by a cathode band on the body, aligning with industry-standard marking conventions. The device weighs approximately 0.400 g and features glass-passivated chip construction for enhanced reliability-key physical traits verified for the 2A01G in TSC's mechanical data sheet.

Does the 2A01G have AEC-Q101 qualification?

No, the base 2A01G part number is not AEC-Q101 qualified. AEC-Q101 qualification is available only for variants marked with an "H" suffix (e.g., 2A01GH). The standard 2A01G is intended for industrial and commercial applications; automotive-grade reliability requires selecting the explicitly qualified 2A01GH version, which undergoes additional stress testing per AEC-Q101 standards.
