Product details

Overview

2A05G A0G from Taiwan Semiconductor is a standard silicon rectifier diode in DO-204AC (DO-15) package, rated for 600 V repetitive peak reverse voltage (V_RRM), 2 A average forward current (I_F), and 70 A non-repetitive surge current (I_FSM). It features low forward voltage (1.0 V max at 2 A, 25°C), 5 µA max reverse leakage at 25°C, and operates up to 150°C junction temperature - used in DC-DC converters and switching-mode power supplies.

For engineers reviewing the 2A05G A0G datasheet, 2A05G A0G pinout, 2A05G A0G application, or 2A05G A0G equivalent, key selection criteria include V_RRM = 600 V, I_F = 2 A, VF ≤ 1.0 V, thermal resistance R_θJL = 25°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. Its 600 V V_RRM rating targets mid-voltage industrial and consumer power stages, while the 2 A continuous forward current supports compact, thermally constrained designs.

The 1.0 V typical forward voltage at 2 A and 25°C reduces conduction loss, and the 70 A I_FSM (8.3 ms half-sine) enables robust handling of transient inrush currents. Junction-to-lead thermal resistance of 25°C/W supports reliable heat transfer to PCB copper when lead-mounted.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - maximum allowable reverse voltage before breakdown; defines safe operating range in 400–500 V DC bus applications.
I_F	2 A - continuous average forward current; sets minimum trace width and heatsinking requirements for steady-state operation.
I_FSM	70 A - non-repetitive surge current capability; determines immunity to line transients and startup inrush in SMPS.
V_F	≤1.0 V @ 2 A, 25°C - forward voltage drop directly impacts conduction loss and thermal rise in high-duty-cycle operation.
R_θJL	25 °C/W - junction-to-lead thermal resistance; enables estimation of junction temperature rise above PCB pad temperature.
I_R	≤5 µA @ 600 V, 25°C - reverse leakage current; critical for low-power standby modes and high-impedance sensing circuits.
T_J max	150 °C - maximum junction temperature; constrains ambient operating range and derating curves per Fig.1.

Pinout & Package

Package: DO-204AC (DO-15), axial-leaded, glass-passivated, RoHS-compliant, halogen-free molding compound (UL 94V-0), pure tin-plated leads. Cathode indicated by band.

Pin/Terminal	Circuit Role	Design Meaning
Anode (unbanded end)	Forward current entry point	Connected to lower-potential side (e.g., transformer secondary center-tap or switch node return path).
Cathode (banded end)	Forward current exit / reverse blocking terminal	Connected to output rail or filter capacitor positive; blocks reverse voltage up to 600 V.

Key Features

Feature	Design Value

High I_FSM (70 A)	Supports direct replacement in legacy 2A rectifier positions without upstream fuse or NTC redesign for inrush management.
DO-204AC mechanical standardization	Ensures compatibility with existing DO-15 footprints, wave solder profiles, and automated insertion tooling.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R06	V_RRM = 600 V, I_F = 2 A, V_F = 1.15 V (typ), R_θJL = 30°C/W, TO-220AC package	Higher thermal resistance and larger footprint; requires heatsink for >1.2 A continuous use	Select when higher surge margin or TO-220 mounting is required; not drop-in for DO-15 boards.
ON Semi MUR260	V_RRM = 600 V, I_F = 2 A, V_F = 0.98 V (typ), ultrafast recovery (t_rr = 50 ns), DO-204AC	Ultrafast recovery reduces switching noise in high-frequency SMPS (>100 kHz); slightly lower V_F	Prefer for noise-sensitive or >100 kHz designs; same footprint but different recovery behavior affects EMI filter sizing.

Compared with STTH2R06 and MUR260, the 2A05G A0G offers optimal balance of low V_F, proven DO-204AC reliability, and cost-effective standard recovery performance - ideal for <100 kHz industrial and consumer power supplies where ultrafast recovery is unnecessary.

FAQ

What is the peak repetitive reverse voltage rating for 2A05G A0G?

The 2A05G A0G has a peak repetitive reverse voltage (V_RRM) rating of 600 V. This value is confirmed in the Absolute Maximum Ratings table across all versions of the 2A01G–2A07G family datasheet. It defines the maximum reverse-biased voltage the device can block repeatedly without breakdown under normal operating conditions.

Is 2A05G A0G RoHS and halogen-free compliant?

Yes, the 2A05G A0G is RoHS compliant and halogen-free per IEC 61249-2-21. The datasheet explicitly states compliance in the FEATURES section and confirms UL 94V-0 flammability rating for the molding compound, supporting environmentally regulated industrial and consumer deployments.

What is the forward voltage of 2A05G A0G at 2 A and 25°C?

The forward voltage (V_F) of the 2A05G A0G is specified as a maximum of 1.0 V at I_F = 2 A and T_J = 25°C. This value applies to the 2A03G–2A07G subgroup, which includes 2A05G A0G, and is measured under pulsed conditions (PW = 0.3 ms) to minimize self-heating effects.

Does 2A05G A0G have AEC-Q101 qualification?

No, the 2A05G A0G variant is not AEC-Q101 qualified. Only parts marked with suffix "H" (e.g., 2A05GH) are AEC-Q101 qualified, as stated in the ORDERING INFORMATION table. The "A0G" suffix denotes ammo box packaging in DO-204AC, not automotive qualification.

What is the thermal resistance from junction to lead for 2A05G A0G?

The junction-to-lead thermal resistance (R_θJL) for 2A05G A0G is 25°C/W, as published in the THERMAL PERFORMANCE section of the datasheet. This parameter is critical for estimating junction temperature rise when the device is soldered to PCB copper and used in natural convection environments.
