Product details
Overview
1N4002G from Taiwan Semiconductor is a glass-passivated silicon standard rectifier diode rated for 1 A average forward current and 100 V repetitive peak reverse voltage, with 30 A surge capability and 1 V max forward voltage at 1 A, used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the 1N4002G datasheet, 1N4002G pinout, 1N4002G application, or 1N4002G equivalent, key selection criteria include VRRM=100 V, IFSM=30 A, VF≤1.0 V @ 1 A, TJ(max)=150 °C, and DO-41 package compatibility with through-hole PCB layouts.
Technical Context
This single-die, unidirectional rectifier operates with a PN junction structure and glass-passivated chip for enhanced moisture resistance and long-term reliability under thermal cycling. Its low forward voltage drop and high surge rating support efficient energy conversion in non-synchronous rectification paths.
The device exhibits 10 pF junction capacitance at 1 MHz and 4 V reverse bias, enabling stable performance in medium-frequency switching applications up to ~100 kHz. Reverse leakage remains ≤5 µA at 25 °C and ≤100 µA at 125 °C, supporting operation across industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage the diode blocks without breakdown; defines usable input voltage range in rectifier stage. |
| IF(AV) | 1 A - Continuous average forward current handling capacity; sets maximum DC output current in linear or low-frequency switched supplies. |
| IFSM | 30 A - Non-repetitive peak surge current (8.3 ms half-sine); enables survival during cold-start inrush or transient overloads. |
| VF(max) | 1.0 V @ 1 A, 25 °C - Forward voltage drop determining conduction loss and thermal dissipation in rectifier path. |
| TJ(max) | +150 °C - Maximum junction temperature; allows operation in enclosed or high-ambient environments with appropriate heatsinking. |
| CJ | 10 pF @ 1 MHz, 4 V - Junction capacitance affecting high-frequency switching noise and reverse recovery behavior. |
| IR(max) | 5 µA @ 25 °C - Reverse leakage current defining off-state power loss and voltage hold capability in standby mode. |
Pinout & Package
Package: DO-204AL (DO-41), axial-leaded, epoxy-molded case with cathode band marking. Leads are pure tin-plated and J-STD-002 solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connects to AC source or transformer secondary side; polarity must align with circuit's forward conduction direction. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4002 | No green compound or halogen-free certification; not AEC-Q101 qualified; identical electrical specs. | Limited to commercial-grade consumer electronics where environmental compliance is not mandated. | Select 1N4002 only if RoHS/halogen-free or automotive qualification is unnecessary and cost is primary. |
| STTH1R02 | Faster recovery (~1.5 µs vs. >30 µs), higher VF (~1.15 V), same 100 V VRRM and 1 A IF rating. | Better suited for higher-frequency switching (>50 kHz); less ideal for low-cost 50/60 Hz rectification due to higher conduction loss. | Choose STTH1R02 when replacing 1N4002G in upgraded SMPS designs requiring reduced reverse recovery time. |
Compared with 1N4002 and STTH1R02, the 1N4002G provides certified halogen-free, RoHS-compliant construction and optional AEC-Q101 qualification-making it preferred for industrial and automotive-adjacent applications where reliability and regulatory compliance are design-critical, while maintaining identical core rectification performance.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the 1N4002G?
The 1N4002G has a VRRM rating of 100 V, meaning it reliably blocks up to 100 volts of reverse-biased voltage in repetitive applications. This value is specified in the Absolute Maximum Ratings table of the Taiwan Semiconductor P2104 datasheet and is confirmed across all official distributor listings. Exceeding this voltage risks avalanche breakdown and permanent damage to the 1N4002G.
Is the 1N4002G RoHS and halogen-free compliant?
Yes, the 1N4002G is both RoHS compliant and halogen-free per IEC 61249-2-21. This is explicitly stated in the Features section of the Taiwan Semiconductor datasheet (Version P2104). The "G" suffix denotes green compound, and the device uses halogen-free molding material-critical for compliance in EU, China, and other regulated markets where the 1N4002G is deployed.
What package type does the 1N4002G use, and how is polarity marked?
The 1N4002G uses the DO-204AL (DO-41) axial package with pure tin-plated leads. Polarity is indicated by a visible cathode band near one lead end, consistent with industry-standard diode marking. This band must be oriented toward the positive side of the load in forward-bias operation. The 1N4002G's mechanical dimensions and lead finish comply with J-STD-002 solderability requirements.
What is the forward voltage drop (VF) of the 1N4002G at rated current?
The 1N4002G has a maximum forward voltage drop of 1.0 V at 1 A forward current and 25 °C junction temperature, as specified in the Electrical Specifications table. Typical VF is lower, but design margins should use the 1.0 V max value to ensure thermal stability. This VF directly impacts conduction losses and heatsink sizing in any application using the 1N4002G as a rectifier.
Does the 1N4002G have automotive qualification?
The base 1N4002G is not AEC-Q101 qualified; however, the variant 1N4002GH (with "H" suffix) is AEC-Q101 qualified. The datasheet clearly separates these versions in the Ordering Information table. For automotive applications requiring stress-tested reliability, specify 1N4002GH-not 1N4002G-to ensure compliance with AEC-Q101 test conditions and failure analysis protocols.
