Product details
Overview
1N4002G-T from Diodes Incorporated is a glass passivated silicon rectifier diode rated for 100 V peak repetitive reverse voltage, 1.0 A average forward current, and 30 A non-repetitive surge current. It features a low 1.0 V forward voltage drop at 1.0 A and 5.0 µA maximum reverse leakage at 25°C, used in AC/DC power supply front-end rectification and DC power rail protection.
For engineers reviewing the 1N4002G-T datasheet, 1N4002G-T pinout, 1N4002G-T application, or 1N4002G-T equivalent, key selection criteria include reverse voltage margin (100 V), thermal resistance (100 °C/W), DO-41 package compatibility, and surge robustness (30 A, 8.3 ms) in cost-sensitive industrial and consumer power supplies.
Technical Context
This device operates as a single-phase, half-wave rectifier under 60 Hz resistive or inductive loads. Its glass passivated die construction ensures stable junction performance and enhanced moisture resistance versus epoxy-passivated alternatives.
Thermal derating begins at 75°C ambient, with full 1.0 A rating maintained only when leads are held at ambient temperature at 9.5 mm from case. Reverse recovery time is 2.0 µs under defined test conditions (IF = 0.5 A, IR = –1 A, Irr = 0.25 A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum peak reverse voltage the diode blocks without breakdown; sets minimum input AC voltage headroom for bridge or half-wave rectifiers. |
| IO @ TA=75°C | 1.0 A - Continuous DC output current capability when ambient temperature is 75°C and leads are thermally anchored per spec. |
| VFM @ IF=1.0A | 1.0 V - Forward conduction loss at rated current; determines ~1.0 W worst-case power dissipation in series rectifier configurations. |
| IFSM (8.3ms) | 30 A - Surge withstand capability during cold-start inrush or line transients; supports basic fuseless design in low-cost adapters. |
| IRM @ 25°C | 5.0 µA - Reverse leakage at rated blocking voltage; critical for low-power standby circuits where quiescent current must be minimized. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance in free-air; defines required heatsinking or board copper area for sustained 1 A operation. |
Pinout & Package
Package: DO-41 plastic case, UL 94V-0 rated, 0.30 g typical weight, cathode indicated by band, tin-plated leads solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary; polarity must align with circuit's positive output path. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; ties to output rail or filter capacitor; reverse voltage applied here during off-cycle. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Eliminates epoxy-related delamination risk and improves long-term reliability in humid or thermally cycled environments. |
| 30 A surge rating (8.3 ms) | Enables direct use in unregulated wall adapters without external inrush limiters for basic consumer electronics. |
| RoHS-compliant lead finish | Tin-plated terminals ensure compatibility with lead-free reflow profiles and eliminate post-solder cleaning requirements. |
| DO-41 standard footprint | Direct replacement for legacy 1N400x series across PCBs, sockets, and automated assembly lines without layout change. |
Applications
| AC/DC Wall Adapter Input Rectification | DC Power Rail Reverse Polarity Protection |
|---|---|
Use Scenario: Converts 120 VAC/60 Hz mains to pulsating DC in low-power (<15 W) offline adapters for IoT sensors and LED drivers. IC Role / Device Role / Timing Role: Half-wave rectifier providing unidirectional current flow into bulk capacitor; no timing function. Use Value: 100 V VRRM provides 2× safety margin over 120 VAC peak (170 V), while 1.0 V VFM limits conduction loss to ≤1 W at full load. | Use Scenario: Placed in series with VCC input of microcontroller boards to prevent damage from accidental reverse battery or supply connection. IC Role / Device Role / Timing Role: Unidirectional current gate; blocks reverse current flow while passing forward current with minimal voltage drop. Use Value: 1.0 V forward drop preserves >95% of 5 V or 3.3 V rail voltage; DO-41 allows manual or automated through-hole insertion on prototyping and production PCBs. |
| Industrial Control Signal Conditioning | Capacitor-Input Filter Stage Protection |
Use Scenario: Clamps and rectifies low-level AC signals (e.g., 24 VAC control inputs) before feeding to optocouplers or ADC front-ends. IC Role / Device Role / Timing Role: Signal-level rectifier and transient clamp; handles <100 mA average current with fast response. Use Value: 2.0 µs trr ensures fidelity of 50–60 Hz control waveforms; 5.0 µA IRM avoids loading high-impedance sensor outputs. | Use Scenario: Positioned between transformer secondary and bulk electrolytic capacitor to limit inrush current and absorb switching spikes. IC Role / Device Role / Timing Role: Primary rectifying element in capacitor-input filter; sustains peak currents during charging cycles. Use Value: 30 A IFSM withstands repeated capacitor-charging surges; 8.0 pF CT minimizes RF coupling into sensitive analog sections. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4002RLG (ON Semiconductor) | Same VRRM (100 V), IO (1.0 A), DO-41 package; slightly higher VFM (1.1 V typ.) and IRM (10 µA max). | Identical functional role but may increase conduction loss by ~0.1 W at 1 A; acceptable where leakage tolerance >5 µA. | Select when sourcing diversification is required and minor VFM/IRM trade-offs are acceptable. |
| STTH1R02 (STMicroelectronics) | Ultrafast recovery (trr ≈ 50 ns), same VRRM/IO, but TO-220AC package - not DO-41 compatible. | Used where EMI reduction or high-frequency rectification is needed; requires PCB redesign due to larger footprint and mounting hole. | Choose only if faster recovery is mandatory and mechanical redesign is feasible. |
Compared with 1N4002RLG, the 1N4002G-T offers lower leakage and forward drop; versus STTH1R02, it trades speed for DO-41 compatibility and cost - making it optimal for legacy-compatible, low-frequency, cost-driven rectification.

FAQ
What is the maximum junction temperature for continuous operation of the 1N4002G-T?
The 1N4002G-T has an operating junction temperature range of –65°C to +175°C. For continuous 1.0 A operation, thermal design must ensure junction temperature stays within this limit - typically requiring ambient ≤75°C with proper lead heat sinking per datasheet note 3 (9.5 mm lead length at ambient).
Can the 1N4002G-T be used in a full-wave bridge configuration?
Yes - four 1N4002G-T diodes can form a discrete full-wave bridge rectifier. Each diode handles half the AC cycle, so the 100 V VRRM rating is sufficient for input RMS voltages up to ~70 VAC. Derating is required for capacitive loads (20% current reduction per datasheet).
Is the 1N4002G-T suitable for high-frequency switching applications?
No - its 2.0 µs reverse recovery time makes it unsuitable for PWM frequencies above ~10 kHz. It is optimized for 50/60 Hz line-frequency rectification. For SMPS or high-frequency inverters, ultrafast or Schottky diodes with trr < 100 ns are recommended.
Does the "-T" suffix indicate tape-and-reel packaging?
Yes - the "-T" suffix denotes 5,000-piece tape-and-reel packaging on 13-inch reels, as confirmed in the ordering information table. This format supports automated SMT placement when used with appropriate carrier tape feeders, though the DO-41 package is primarily through-hole.
