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 150 °C maximum junction temperature, 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 its DO-41 package compatibility, low 1 V forward voltage at 1 A, 5 µA max reverse leakage at 25 °C, 10 pF junction capacitance, and AEC-Q101 qualified variants for automotive-grade reliability.
Technical Context
The 1N4002G operates as a single-die, unidirectional PN-junction rectifier with glass-passivated chip construction ensuring stable performance under thermal cycling and humidity stress. Its 100 V VRRM rating targets mid-voltage AC/DC front-end and secondary-side rectification where higher voltage margins than 1N4001G are required but 200 V+ devices are over-specified.
Thermal resistance of 80 °C/W (junction-to-ambient) and 150 °C maximum junction temperature enable operation up to 75 °C ambient at full 1 A load without derating, while the 30 A non-repetitive surge rating supports inrush current handling in offline switchers and transformer-coupled supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor 1N4002 | Same 100 V VRRM, 1 A IF, DO-41 package; VF = 1.1 V max (vs. 1.0 V for 1N4002G); no AEC-Q101 option | General-purpose use only; not qualified for automotive environments | Select when cost sensitivity outweighs automotive qualification or ultra-low VF requirement |
| Vishay 1N4002-E3/54 | Identical electrical ratings; RoHS-compliant; VF = 1.0 V max; available in tape-and-reel (5,000 pcs) and bulk (3,000 pcs) | No AEC-Q101 variant; slightly higher RθJA (85 °C/W vs. 80 °C/W) | Prefer for high-volume automated assembly where packaging format and consistency matter most |
Compared with ON Semiconductor 1N4002 and Vishay 1N4002-E3/54, the 1N4002G offers tighter forward voltage control and optional AEC-Q101 qualification-critical for automotive auxiliary supplies-while maintaining identical footprint and basic electrical behavior for drop-in replacement in legacy designs.

FAQ
What is the maximum junction temperature for the 1N4002G?
The 1N4002G has a maximum junction temperature (TJ) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet P2104. This allows continuous operation at full 1 A forward current up to 75 °C ambient temperature when mounted on a standard PCB with minimal copper area. Exceeding this limit risks irreversible thermal runaway and parametric shift in the 1N4002G.
Does the 1N4002G have AEC-Q101 qualification?
Yes-the 1N4002G is available in an AEC-Q101 qualified version designated as 1N4002GH, confirmed in the Ordering Information section of the Taiwan Semiconductor datasheet P2104. The "H" suffix indicates full qualification for automotive applications including temperature cycling, humidity testing, and mechanical shock. Standard 1N4002G is not AEC-Q101 qualified unless explicitly ordered as 1N4002GH.
What is the forward voltage drop of the 1N4002G at rated current?
The 1N4002G exhibits a maximum forward voltage (VF) of 1.0 V at 1 A forward current and 25 °C junction temperature, as specified in the Electrical Specifications table of the P2104 datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At elevated temperatures or higher currents, VF decreases slightly due to negative temperature coefficient of silicon diodes.
Can the 1N4002G replace the 1N4001G in a design?
Yes-the 1N4002G can directly replace the 1N4001G because both share identical package (DO-41), pinout, forward current (1 A), surge rating (30 A), and thermal specifications. The only difference is reverse voltage rating: 1N4001G is rated for 50 V VRRM, while the 1N4002G is rated for 100 V. Using 1N4002G improves margin against transients without altering layout or thermal design.
What is the reverse leakage current of the 1N4002G at 100 V and 125 °C?
At 100 V reverse voltage and 125 °C junction temperature, the 1N4002G exhibits a maximum reverse leakage current (IR) of 100 µA, as documented in the Electrical Specifications table of the P2104 datasheet. This value is critical for low-power standby circuits where leakage contributes significantly to quiescent current. At room temperature (25 °C), leakage is limited to 5 µA max.
