Product details
Overview
2A05GH from Taiwan Semiconductor is a glass-passivated standard silicon rectifier diode rated for 600 V repetitive peak reverse voltage, 2 A average forward current, and 70 A non-repetitive surge current, with low 1.0 V forward voltage at 2 A and 25°C - used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the 2A05GH datasheet, 2A05GH pinout, 2A05GH application, or 2A05GH equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package, thermal resistance (RθJL = 25°C/W), junction capacitance (15 pF), and reverse leakage (≤5 µA at 25°C).
Technical Context
This device is a single-die, general-purpose axial-lead rectifier optimized for high-efficiency AC/DC and DC/DC conversion stages where reliability under surge and elevated temperature is critical. It features a glass-passivated junction for moisture and contamination resistance, and meets JESD201 Class 2 whisker testing.
Thermally, it delivers RθJL = 25°C/W and RθJC = 22°C/W, enabling stable operation up to TJ = 150°C. Its 15 pF junction capacitance at 4 V reverse bias supports moderate-frequency switching applications without excessive capacitive loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage before breakdown; defines safe operating range in bridge or flyback snubber circuits |
| IF | 2 A - continuous average forward current at TA = 75°C; determines heatsink sizing in linear-regulator bypass or output rectification |
| IFSM | 70 A - peak non-repetitive surge current (8.3 ms half-sine); withstands inrush in SMPS startup or motor drive freewheeling |
| VF | 1.0 V @ 2 A, 25°C - forward drop directly impacts conduction loss and thermal rise in high-duty-cycle rectifiers |
| RθJL | 25 °C/W - junction-to-lead thermal resistance; enables direct PCB copper pour cooling without external heatsink in low-power designs |
| CJ | 15 pF @ 1 MHz, 4 V - limits high-frequency noise coupling and EMI generation in >100 kHz switching topologies |
Pinout & Package
Package: DO-204AC (DO-15), axial-lead, glass-passivated, RoHS- and halogen-free compliant, cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential side of AC source or switch node; requires adequate trace width for 2 A continuous current |
| Cathode (Lead 2) | Forward current exit / reverse blocking terminal | Marked with band; ties to positive rail or output capacitor; must sustain 600 V transient spikes in flyback designs |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per stress test requirements |
| Glass-passivated junction | Eliminates need for conformal coating in humid or contaminated environments; extends field life in industrial controls |
| Low VF (1.0 V) | Reduces conduction loss by ~15% vs. comparable 1.15 V diodes at 2 A, lowering thermal load in sealed enclosures |
| High IFSM (70 A) | Supports robust operation during line surges or motor stall events without catastrophic failure |
| RoHS + halogen-free | Complies with IEC 61249-2-21; eliminates brominated flame retardants for safer end-of-life processing |
Applications
| DC-DC Converter Output Rectification | Switching Mode Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 48 V–12 V buck-derived DC-DC modules for telecom power systems. IC Role / Device Role / Timing Role: Unidirectional current steering and AC-to-DC conversion; replaces synchronous MOSFET where gate drive complexity is undesirable. Use Value: 1.0 V VF minimizes power loss at 2 A load, while 600 V VRRM accommodates reflected transients from transformer leakage inductance. | Use Scenario: Freewheeling path across inductive loads (e.g., BLDC motor phases) in 3-phase inverters for HVAC compressors. IC Role / Device Role / Timing Role: Clamping inductive kickback during PWM turn-off; operates in uncontrolled conduction mode. Use Value: 70 A IFSM safely absorbs energy from 200 mH coils at 2 A, and 150°C TJMAX ensures stability under sustained thermal stress. |
| Industrial AC-DC Power Supply Input Bridge | Automotive Body Control Module (BCM) Power Conditioning |
Use Scenario: Single-diode element in full-wave bridge rectifier for 230 VAC input, 15 W industrial control power supply. IC Role / Device Role / Timing Role: Half-wave rectification stage feeding bulk capacitor; operates at 50/60 Hz with minimal switching loss. Use Value: Glass passivation prevents corrosion in factory-floor humidity; 600 V rating provides 2× safety margin over peak line voltage (325 V). | Use Scenario: Reverse-polarity protection and load-dump clamping in 12 V BCM power rails exposed to ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Standby-path rectifier and transient suppressor; leverages AEC-Q101 qualification for automotive deployment. Use Value: AEC-Q101 qualification ensures survivability through 1,000+ thermal cycles; 5 µA max IR at 25°C preserves battery standby current budget. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same DO-15 package, 600 V VRRM, but higher VF (1.15 V typ), no AEC-Q101 qualification | Not validated for automotive use; suitable for industrial/commercial only | Select when AEC-Q101 is not required and cost sensitivity outweighs 150 mV VF penalty |
| ON Semi MUR260 | Ultrafast recovery (trr = 50 ns), same VRRM/IF, but VF = 1.25 V and no AEC-Q101 | Better for high-frequency (>100 kHz) switching; higher conduction loss | Prefer for PFC or resonant LLC where reverse recovery matters more than forward loss |
Compared with STTH2R06 and MUR260, the 2A05GH uniquely combines AEC-Q101 qualification, 1.0 V VF, and DO-15 compatibility - making it optimal for automotive and thermally constrained industrial rectification where reliability and efficiency are jointly prioritized.

FAQ
What is the peak repetitive reverse voltage rating for the 2A05GH?
The 2A05GH has a peak repetitive reverse voltage (VRRM) rating of 600 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version I2105). It defines the maximum reverse-biased voltage the diode can block continuously without breakdown, and is critical for selecting appropriate safety margins in bridge rectifier or flyback transformer clamp designs.
Is the 2A05GH qualified to AEC-Q101 standards?
Yes, the 2A05GH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST), validating its suitability for automotive under-hood and body electronics applications.
What is the forward voltage drop of the 2A05GH at rated current?
The 2A05GH exhibits a maximum forward voltage (VF) of 1.0 V at IF = 2 A and TJ = 25°C, per the Electrical Specifications table. This low VF reduces conduction losses and thermal dissipation compared to higher-drop alternatives, supporting efficient operation in space-constrained or thermally limited designs using the 2A05GH.
What package type does the 2A05GH use, and what are its mechanical identifiers?
The 2A05GH uses the DO-204AC (DO-15) axial-leaded package. Mechanical identifiers include a glass-passivated chip junction, pure tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, cathode polarity marked by a visible band, and approximate weight of 0.400 g - all specified in the MECHANICAL DATA section of the Taiwan Semiconductor datasheet.
Does the 2A05GH have a specified junction capacitance, and why does it matter?
Yes, the 2A05GH has a typical junction capacitance (CJ) of 15 pF measured at 1 MHz and 4.0 V reverse bias. This parameter influences high-frequency switching behavior: lower CJ reduces capacitive coupling and EMI generation in DC-DC converters operating above 100 kHz, and affects snubber design in inductive switching circuits where the 2A05GH is deployed.
