Product details
Overview
2A02G A0G from Taiwan Semiconductor is a 2 A, 100 V glass-passivated 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 inverters.
For engineers reviewing the 2A02G A0G datasheet, 2A02G A0G pinout, 2A02G A0G application, or 2A02G A0G equivalent, key selection factors include repetitive peak reverse voltage (100 V), forward current rating (2 A), thermal resistance (RθJL = 25 °C/W), and AEC-Q101 qualification availability via alternate marking.
Technical Context
This single-die standard rectifier operates with a maximum junction temperature of 150 °C and exhibits low power loss due to its 1.1 V typical forward voltage at 2 A and 5 µA reverse leakage at 25 °C. Its glass-passivated junction ensures reliability under thermal cycling and humidity stress.
The device uses a DO-204AC (DO-15) axial leaded package with pure tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Polarity is marked by a cathode band, and the molding compound meets UL 94V-0.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage before breakdown |
| IF | 2 A - Continuous average forward current under specified thermal conditions |
| IFSM | 70 A - Non-repetitive surge current tolerance for 8.3 ms half-sine wave |
| VF @ 2 A | 1.1 V - Forward voltage drop determining conduction loss in power stage |
| RθJL | 25 °C/W - Junction-to-lead thermal resistance enabling direct PCB copper heat sinking |
| IR @ 25°C | 5 µA - Reverse leakage current affecting standby power and high-impedance bias networks |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, glass-passivated die, cathode indicated by band, weight ≈ 0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential side of circuit; requires adequate trace width for 2 A continuous current |
| Cathode (Lead 2, banded end) | Forward current exit / reverse blocking terminal | Connected to higher-potential node; polarity marking critical for correct orientation in bridge or freewheeling paths |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances moisture resistance and long-term reliability in humid or condensing environments |
| Low VF (1.1 V @ 2 A) | Reduces conduction losses in high-duty-cycle rectification stages, improving system efficiency |
| 70 A IFSM | Withstands transient inrush currents during startup or fault recovery without degradation |
| UL 94V-0 molding compound | Meets flammability safety requirements for industrial and automotive power supply enclosures |
Applications
| DC-DC Converter Output Rectification | Switching Inverter Freewheeling Diode |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 5–24 V at up to 2 A. IC Role / Device Role / Timing Role: Unidirectional current conduction path converting transformer AC output to regulated DC. Use Value: 1.1 V VF minimizes power loss at full load; 70 A IFSM handles output capacitor charging surges. | Use Scenario: Freewheeling path across inductive loads (e.g., motor windings or relay coils) in H-bridge inverters. IC Role / Device Role / Timing Role: Provides safe current recirculation during switch-off transitions to clamp inductive kickback. Use Value: 100 V VRRM supports 48 V bus systems; 150 °C TJMAX enables operation near heatsinked MOSFETs. |
| Industrial Power Supply Input Stage | Automotive Auxiliary Power Module |
Use Scenario: Input rectification in offline 24 V/48 V industrial SMPS with universal AC input. IC Role / Device Role / Timing Role: Half-wave or full-wave rectifier in bridge configuration feeding bulk capacitor. Use Value: Glass passivation prevents corrosion in factory-floor environments; DO-15 package allows manual or automated through-hole assembly. | Use Scenario: 12 V auxiliary power conversion in engine control units or body electronics modules. IC Role / Device Role / Timing Role: Secondary-side rectifier in isolated DC-DC for isolated CAN or sensor supplies. Use Value: AEC-Q101 qualification available (via 2A02GH variant); 5 µA IR at 25 °C preserves battery standby life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R01AP | 100 V, 2 A, TO-220AC package, VF = 1.05 V typ, RθJA = 50 °C/W | Higher thermal mass and mounting flexibility; not axial-leaded | Preferred where board space allows screw-mount heatsinking and higher surge margin is needed |
| ON Semi MUR220 | 200 V, 2 A, DO-204AC, VF = 0.92 V typ, ultrafast recovery (trr = 35 ns) | Higher VRRM, faster switching, lower VF; not optimized for low-frequency rectification | Selected when operating above 20 kHz or requiring reduced switching loss in PFC stages |
Compared with STTH2R01AP and MUR220, the 2A02G A0G offers cost-effective axial-leaded construction with proven reliability in 50–100 V DC-DC outputs, but lacks ultrafast recovery or TO-220 thermal performance-making it optimal for fixed-frequency, medium-power rectification where leaded assembly and JEDEC-standard footprint are required.

Manufacturer
Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving industrial, computing, and automotive markets since 1979.
The 2A02G A0G belongs to TSC's standard rectifier family designed for cost-sensitive, medium-current power conversion applications where reliability, thermal robustness, and JEDEC-standard packaging are prioritized over ultrafast switching.
FAQ
What is the maximum junction temperature rating for the 2A02G A0G?
The 2A02G A0G has a maximum junction temperature (TJ) rating of +150 °C, verified per absolute maximum ratings table in the official TSC datasheet Version I2105. This allows operation in high-ambient environments such as enclosed power supplies or near heat-generating components. Derating curves confirm usable current down to 0 A at 150 °C ambient when mounted on standard FR-4 PCB with minimum copper area.
Does the 2A02G A0G have AEC-Q101 qualification?
The 2A02G A0G itself is not AEC-Q101 qualified; however, the functionally identical 2A02GH variant (same electrical specs, DO-204AC package) carries full AEC-Q101 qualification. The "H" suffix denotes automotive-grade screening, including extended temperature cycling and bias-HAST testing. For automotive designs, specify 2A02GH instead of 2A02G A0G.
What is the forward voltage of the 2A02G A0G at 2 A and 125 °C junction temperature?
The datasheet specifies VF = 1.1 V maximum at IF = 2 A and TJ = 25 °C. While no explicit VF value is given at 125 °C, typical forward voltage decreases ~2 mV/°C for silicon rectifiers; thus, VF at 125 °C is estimated at ~0.9 V. Actual measurement under bias is recommended for precision thermal modeling of the 2A02G A0G.
Can the 2A02G A0G be used as a replacement for the 1N4002?
No-the 2A02G A0G is not a direct replacement for the 1N4002. Although both are DO-204AC rectifiers, the 1N4002 is rated for only 1 A average forward current and 100 V VRRM, while the 2A02G A0G delivers 2 A continuous current and shares the same 100 V rating. Substituting requires verifying PCB trace width, thermal relief, and surge margin-especially since 2A02G A0G draws twice the conduction current at same VF.
What does the "A0G" suffix mean in 2A02G A0G?
The "A0G" suffix in 2A02G A0G indicates the packaging format: DO-204AC (DO-15) in 1,500-piece ammo box packaging. Per TSC ordering information, "A0G" distinguishes this bulk-packaged version from the tape-and-reel variant (2A02G), and "G" confirms green (halogen-free) molding compound per IEC 61249-2-21.
