Product details
Overview
D2G-T from Diodes Incorporated is a 1.0A glass passivated general-purpose rectifier diode with 100V peak repetitive reverse voltage (VRRM), 1.0V forward voltage at 1.0A (VFM), and 30A non-repetitive surge capability (IFSM), used in AC/DC input stage rectification for power supplies and adapters.
For engineers reviewing the D2G-T datasheet, D2G-T pinout, D2G-T application, or D2G-T equivalent, key selection criteria include its T-1 molded plastic package, 100°C/W junction-to-ambient thermal resistance, 2.0µs typical reverse recovery time, and RoHS-compliant tin-plated terminals suitable for automated assembly.
Technical Context
This device operates as a single-phase, half-wave silicon rectifier optimized for resistive or inductive loads at 60Hz. It features glass passivated die construction for enhanced reliability and moisture resistance, with polarity indicated by a cathode band.
Thermal derating applies above 75°C ambient: average forward current drops linearly to zero at 150°C. Capacitive load operation requires 20% current derating due to higher peak currents during charging transients.
Key Specifications

| VRRM | 100 V - Maximum peak reverse voltage the diode blocks without breakdown in repetitive operation |
| IO @ TA=75°C | 1.0 A - Continuous average forward current rating under specified thermal conditions |
| VFM @ IF=1.0A | 1.0 V - Forward voltage drop determining conduction loss and thermal dissipation |
| IFSM (8.3ms) | 30 A - Surge current handling capability for transient line events or inrush |
| trr (typ) | 2.0 µs - Reverse recovery time affecting switching losses in higher-frequency applications |
| RθJA | 100 °C/W - Thermal resistance defining temperature rise per watt of power dissipation in free air |
| IRM @ 25°C | 5.0 µA - Peak reverse leakage current at rated blocking voltage and room temperature |
Pinout & Package
The D2G-T uses a T-1 axial leaded package with molded plastic case (UL 94V-0), cathode band marking, and tin-plated solderable leads. Total weight is approximately 0.13 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | Forward current exit point | Connected to output filter capacitor or load return; marked with band for polarity identification |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Improved surface stability and long-term reliability under humid or high-bias stress conditions |
| 30A surge rating | Withstands short-duration line surges without failure, reducing need for external clamping |

Applications
| AC-DC Power Adapter Input Stage | Industrial Control Power Supply |
|---|---|
Use Scenario: Rectifying 50/60Hz AC mains or transformer secondary output into unregulated DC bus. IC Role / Device Role / Timing Role: General-purpose rectifier conducting only during positive half-cycles. Use Value: Low 1.0V VFM minimizes conduction loss at 1A; 100V VRRM supports 85–265VAC input with margin. | Use Scenario: Converting auxiliary AC supply to DC for PLC I/O modules or sensor interface rails. IC Role / Device Role / Timing Role: Discrete rectifier providing isolated, low-noise DC bias for analog circuitry. Use Value: 2.0µs trr limits switching noise; glass passivation ensures stable performance in dusty, high-vibration environments. |
| LED Driver Bulk Rectification | Appliance Motor Control Auxiliary Supply |
Use Scenario: Generating low-voltage DC for LED driver IC bias and gate drive circuits. IC Role / Device Role / Timing Role: Primary rectifier feeding bulk capacitor in offline flyback or buck-derived topologies. Use Value: 30A IFSM accommodates cold-start inrush into large electrolytic capacitors without degradation. | Use Scenario: Providing isolated +12V or +24V rail for motor driver logic and optocoupler interfaces. IC Role / Device Role / Timing Role: Standalone rectifier in low-power auxiliary winding circuit. Use Value: UL 94V-0 case material meets appliance flammability requirements; 0.13g weight supports compact board layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4002-T | Same 100V VRRM, but higher VFM (1.1V typ) and lower IFSM (25A) | Suitable for lower-cost, non-surge-critical designs | Prefer D2G-T where surge robustness or lower conduction loss is required |
| ES1B | Surface-mount SMB package, faster trr (35ns), lower VFM (0.95V), but lower IO (1A avg @ TC=110°C) | Better suited for space-constrained or higher-frequency SMPS front-ends | Choose ES1B only when SMT assembly and faster recovery are mandatory |
Compared with 1N4002-T and ES1B, the D2G-T offers superior surge immunity and axial-leaded ease of prototyping while maintaining competitive forward loss-making it optimal for cost-sensitive, through-hole AC/DC inputs where reliability under transient stress is prioritized.

FAQ
What is the maximum operating temperature for D2G-T?
The D2G-T has an operating junction temperature range of –65°C to +150°C. Its average forward current rating is specified at 75°C ambient, with linear derating to zero at 150°C. The 100°C/W RθJA value means that at 1.0A and 1.0V drop (1.0W dissipation), junction temperature rises 100°C above ambient-so ambient must be ≤50°C for safe full-load operation.
Is D2G-T suitable for use with capacitive loads?
Yes, but with a 20% reduction in average forward current rating (to 0.8A) due to high inrush currents during capacitor charging. This derating ensures safe operation without thermal runaway or premature failure. The 30A IFSM rating helps absorb initial surge, but sustained capacitive loading still requires careful thermal design and possibly additional inrush limiting.
Does D2G-T have lead-free and RoHS compliance documentation?
Yes-D2G-T carries a lead-free finish and is RoHS compliant per EU Directive 2002/95/EC, with all applicable exemptions applied. The tin-plated terminals meet MIL-STD-202 Method 208 solderability requirements, and the device is rated Moisture Sensitivity Level 1, eliminating bake requirements before assembly.
How does the T-1 package differ from DO-41 in mechanical compatibility?
The T-1 package has a 2.60–3.20 mm body diameter and 25.40 mm lead length (min), with leads spaced for standard axial insertion. DO-41 packages are slightly larger (3.6–4.2 mm diameter) and typically longer (38 mm min). While both are axial, T-1's smaller profile allows tighter board spacing, but footprint and hole size must be verified-D2G-T is not mechanically interchangeable with DO-41 devices without layout revision.
