Product details
Overview
2A03GHR0G from Taiwan Semiconductor is a standard glass-passivated 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. It serves as a primary AC/DC conversion element in off-line power supplies and DC-DC converters.
For engineers reviewing the 2A03GHR0G datasheet, 2A03GHR0G pinout, 2A03GHR0G application, or 2A03GHR0G equivalent, key selection criteria include VRRM = 200 V, IF = 2 A, VF ≤ 1.0 V (typ), IFSM = 70 A, and DO-204AC (DO-15) package compatibility with through-hole PCB assembly and high-temperature operation up to TJ = 150°C.
Technical Context
This device is a single-die, planar-junction, standard recovery rectifier optimized for general-purpose switching-mode power conversion. Its glass-passivated junction ensures stable reverse leakage (<5 µA at 25°C, <100 µA at 125°C) and robust surge handling under 8.3 ms half-sine wave conditions.
Thermal performance is defined by RθJL = 25°C/W and RθJA = 60°C/W in free-air, supporting reliable operation in compact, convection-cooled designs. Junction capacitance is 15 pF at 1 MHz and 4 V reverse bias, minimizing high-frequency switching noise coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in bridge or output rectification stages. |
| IF(AV) | 2 A - Continuous average forward current at TA = 75°C; defines steady-state power delivery capability. |
| IFSM | 70 A - Peak non-repetitive surge current (8.3 ms half-sine); supports inrush and transient overload tolerance. |
| VF | 1.0 V (typ) at IF = 2 A, TJ = 25°C - Forward conduction loss directly impacts efficiency and thermal design of rectifier stage. |
| TJ max | +150°C - Maximum junction temperature; enables operation in high-ambient industrial environments without derating. |
| CJ | 15 pF at 1 MHz, VR = 4 V - Junction capacitance affects high-frequency reverse recovery behavior and EMI generation. |
Pinout & Package
Package: DO-204AC (DO-15), axial-lead, glass-passivated, RoHS- and halogen-free molded case with cathode band polarity marking. Weight ≈ 0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node) in half-wave or full-wave configurations. |
| Cathode (Lead 2, banded end) | Forward current exit / reverse blocking terminal | Connected to output filter capacitor positive rail; cathode band must align with PCB silkscreen polarity indicator. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| AC/DC Adapter Power Supply | Industrial DC-DC Converter |
|---|---|
Use Scenario: Off-line 5–24 V output adapter for consumer electronics, using flyback topology with discrete diode rectification. IC Role / Device Role / Timing Role: Output rectifier converting high-frequency transformer secondary AC to regulated DC; operates at 50–100 kHz switching frequency. Use Value: 200 V VRRM safely handles reflected flyback voltage spikes; 1.0 V VF minimizes conduction loss and improves light-load efficiency. | Use Scenario: 48 V input to 12 V isolated DC-DC module in factory automation PLC power rails. IC Role / Device Role / Timing Role: Secondary-side synchronous or standard rectifier in forward or push-pull converter; subjected to repeated surge events during motor startup. Use Value: 70 A IFSM withstands repetitive inrush surges; 150°C TJ max supports operation inside sealed control cabinets. |
| Solar Microinverter Auxiliary Supply | LED Driver Input Rectification |
Use Scenario: Auxiliary 12 V supply derived from PV string voltage via buck-derived auxiliary converter in microinverter. IC Role / Device Role / Timing Role: Input-stage rectifier converting rectified AC or high-voltage DC to intermediate bus; exposed to wide ambient temperature swings (-40°C to +85°C). Use Value: -55°C to +150°C storage/junction range ensures reliability across outdoor deployment; low IR (<5 µA @ 25°C) prevents standby power drain. | Use Scenario: Bridge rectifier in constant-current LED driver for street lighting, operating continuously at elevated ambient temperatures. IC Role / Device Role / Timing Role: Primary AC input rectification feeding bulk capacitor; conducts 2 A RMS current with high ripple content. Use Value: DO-204AC package allows manual or automated axial insertion; UL 94V-0 compound meets luminaire fire safety requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR220G | Ultrafast recovery (trr ≈ 50 ns vs. 2A03GHR0G's standard ~2 µs), VF = 1.15 V (max), same DO-204AC package. | Better suited for higher-frequency SMPS (>200 kHz) where reverse recovery loss dominates; less optimal for cost-sensitive 50–100 kHz designs. | Select MUR220G when trr-driven EMI or efficiency at >150 kHz is critical; retain 2A03GHR0G for general-purpose, thermally constrained, or cost-optimized rectification. |
| Vishay 1N5622 | Same VRRM (200 V), IF = 2 A, but VF = 1.1 V (max), higher RθJA (70°C/W), no AEC-Q101 option. | Limited to commercial-temperature industrial use; lacks automotive qualification and tighter thermal resistance. | Choose 1N5622 only for non-automotive, non-critical thermal environments; prefer 2A03GHR0G when AEC-Q101 compliance or lower thermal resistance is required. |
Compared with MUR220G and 1N5622, the 2A03GHR0G offers the lowest typical VF (1.0 V), best thermal resistance (RθJA = 60°C/W), and optional AEC-Q101 qualification-making it optimal for cost-sensitive, thermally demanding, or automotive-adjacent rectifier applications where standard recovery speed is sufficient.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for the 2A03GHR0G?
The 2A03GHR0G has a VRRM rating of 200 V, meaning it can block up to 200 V of reverse voltage repeatedly without breakdown. This value is confirmed in the Absolute Maximum Ratings table on page 2 of the official Taiwan Semiconductor datasheet (Version I2105), and applies under standard test conditions (TA = 25°C). Exceeding this voltage risks irreversible junction failure.
Does the 2A03GHR0G have AEC-Q101 qualification?
No - the base 2A03GHR0G part number does not include the "H" suffix, which denotes AEC-Q101 qualification per Taiwan Semiconductor's ordering code convention. The AEC-Q101-qualified version is designated 2A03GHR0GH. The "H" suffix is explicitly required in the ordering code to ensure automotive-grade stress testing and reliability validation.
What is the typical forward voltage (VF) of the 2A03GHR0G at rated current?
The 2A03GHR0G exhibits a typical forward voltage of 1.0 V at IF = 2 A and TJ = 25°C, as specified in the Electrical Specifications table (page 2, Version I2105). This value is measured under pulsed conditions (PW = 0.3 ms) and represents the conduction loss baseline used for thermal and efficiency calculations in power supply design.
Which package type does the 2A03GHR0G use, and what are its mechanical identifiers?
The 2A03GHR0G uses the DO-204AC (also known as DO-15) axial-leaded package. Key identifiers include a molded epoxy body meeting UL 94V-0, pure tin-plated leads compliant with J-STD-002, cathode polarity indicated by a visible band, and approximate weight of 0.400 g. Dimensions conform to JEDEC outline MS-001.
What is the surge current rating (IFSM) for the 2A03GHR0G, and under what waveform is it specified?
The 2A03GHR0G is rated for a non-repetitive peak forward surge current (IFSM) of 70 A, tested using an 8.3 ms single half-sine wave superimposed on rated load, per the Absolute Maximum Ratings table. This rating validates its ability to survive inrush currents during power-up or short-duration overloads in real-world power supply applications.
