Product details

Overview

2A03G R0G from Taiwan Semiconductor is a glass-passivated standard silicon rectifier diode rated for 200 V repetitive peak reverse voltage, 2 A average forward current, and 70 A non-repetitive surge current, with 1.0 V typical forward voltage at 2 A and 25°C - used in DC-DC converters and switching-mode power supplies.

For engineers reviewing the 2A03G R0G datasheet, 2A03G R0G pinout, 2A03G R0G application, or 2A03G R0G equivalent, key selection criteria include VRRM = 200 V, IF = 2 A, VF ≤ 1.0 V (TJ = 25°C), IFSM = 70 A, and DO-204AC (DO-15) package compatibility with automated PCB assembly.

Technical Context

This single-die standard rectifier operates as a unidirectional current-conducting device with cathode-band polarity indication, optimized for high-efficiency AC-to-DC conversion in medium-power switching topologies. Its glass-passivated junction ensures stable performance under thermal cycling and humidity stress.

Thermal resistance values are R_θJL = 25°C/W and R_θJA = 60°C/W, supporting reliable operation up to T_J = 150°C. Reverse leakage remains ≤5 µA at 25°C and ≤100 µA at 125°C under rated V_R.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum allowable reverse voltage before breakdown; defines safe operating range in bridge or flyback snubber circuits
I_F	2 A - continuous average forward current rating; determines heatsink requirements and duty-cycle limits
I_FSM	70 A - peak non-repetitive surge current (8.3 ms half-sine); supports inrush and transient overload handling
V_F	≤1.0 V @ 2 A, 25°C - low conduction loss improves efficiency in high-frequency SMPS designs
T_J max	150°C - maximum junction temperature; sets thermal derating envelope for ambient and layout design
C_J	15 pF @ 1 MHz, 4 V - low junction capacitance minimizes switching noise and EMI in fast-switching applications

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side of AC input or transformer secondary; requires trace width sizing for 2 A continuous
Cathode	Forward current exit point	Marked by black band; connects to output capacitor or switching node; critical for correct polarity in full-wave bridges

Key Features

Feature	Design Value
Glass-passivated junction	Enables stable long-term reliability under humid or thermally cycled environments without hermetic sealing
AEC-Q101 qualified option available	Supports automotive-grade qualification path when ordered as 2A03GH variant; not inherent to R0G suffix
Low V_F (≤1.0 V)	Reduces conduction losses by ~15% vs. legacy 1N540x series at 2 A, improving thermal margin in compact layouts
High I_FSM/I_F ratio (35:1)	Provides robustness against line surges and startup transients without external fusing in many 24–48 V systems

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R02	V_RRM = 200 V, I_F = 2 A, V_F = 0.95 V typ., DO-15, but faster recovery (t_rr = 50 ns)	Better suited for higher-frequency (>100 kHz) flyback or PFC stages due to soft recovery	Select STTH2R02 only if t_rr < 100 ns is required; otherwise 2A03G R0G offers lower cost and identical V_RRM/I_F rating
1N5402	V_RRM = 100 V, I_F = 3 A, V_F = 1.2 V typ., DO-204AL (DO-27), higher V_F, lower V_RRM	Limited to ≤100 V applications; unsuitable for 200 V bus or universal-input rectification	Only acceptable if system V_R < 85 V and layout permits larger DO-27 footprint; not a direct replacement for 2A03G R0G

Compared with STTH2R02 and 1N5402, the 2A03G R0G delivers optimal balance of 200 V rating, 2 A capacity, and 1.0 V forward drop in the widely adopted DO-15 package - making it preferred for cost-sensitive, medium-frequency industrial and lighting power supplies where ultrafast recovery is unnecessary.

FAQ

What is the peak repetitive reverse voltage rating of the 2A03G R0G?

The 2A03G R0G has a peak repetitive reverse voltage (V_RRM) rating of 200 V. This value is confirmed in the Absolute Maximum Ratings table across all versions of the 2A01G–2A07G datasheet (Version I2105). It defines the maximum reverse-bias voltage the device can block continuously without breakdown under normal operating conditions.

Does the 2A03G R0G meet AEC-Q101 automotive qualification?

No, the 2A03G R0G is not AEC-Q101 qualified. The base part number 2A03G does not include the "H" suffix; only variants like 2A03GH are explicitly marked as AEC-Q101 qualified per the Ordering Information section. The R0G suffix indicates standard commercial-grade packaging and testing, not automotive qualification.

What is the forward voltage drop of the 2A03G R0G at rated current?

The 2A03G R0G exhibits a typical forward voltage (V_F) of 1.0 V at I_F = 2 A and T_J = 25°C, as specified in the Electrical Specifications table. The maximum V_F is not stated, but the 1.0 V typ. value applies to the entire 2A03G–2A07G group and is measured using a 0.3 ms pulse test.

Which package type is used for the 2A03G R0G?

The 2A03G R0G uses the DO-204AC (commonly known as DO-15) package - an axial-leaded, molded plastic case with glass-passivated chip junction. Mechanical data confirm case outline compliance, UL 94V-0 flammability rating, and pure tin-plated leads meeting J-STD-002 solderability standards.

What is the maximum surge current capability of the 2A03G R0G?

The 2A03G R0G supports a non-repetitive peak forward surge current (I_FSM) of 70 A for an 8.3 ms single half-sine wave, as defined in the Absolute Maximum Ratings table. This rating enables robust handling of inrush currents and short-duration overloads common in AC-input power supplies and motor drives.
