Product details
Overview
1N4004G-K from Taiwan Semiconductor is a standard silicon rectifier diode with 1 A average forward current, 400 V repetitive peak reverse voltage (VRRM), and 30 A surge capability, designed for unidirectional AC-to-DC conversion in power supply front-ends and low-frequency rectification circuits.
For engineers reviewing the 1N4004G-K datasheet, 1N4004G-K pinout, 1N4004G-K application, or 1N4004G-K equivalent, key selection criteria include its DO-41 package compatibility, 1.0 V max forward voltage at 1 A, 5 µA max reverse leakage at 25°C, junction temperature range of –55°C to +150°C, and RoHS/halogen-free compliance for industrial and consumer power designs.
Technical Context
The 1N4004G-K operates as a single-die, PN-junction rectifier with glass-passivated chip construction for enhanced moisture and contamination resistance. Its thermal resistance (RθJA) is 80°C/W, enabling reliable operation up to 150°C junction temperature under natural convection.
It delivers stable DC output in line-frequency (50/60 Hz) applications with low power loss due to its 1.0 V typical forward voltage and 10 pF junction capacitance at 1 MHz/4 V - characteristics optimized for general-purpose rectification rather than high-speed switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum non-repetitive reverse voltage the diode blocks without breakdown in AC line applications |
| IF(AV) | 1 A - continuous average forward current rating at 75°C ambient, defining usable DC load capacity |
| IFSM | 30 A - peak non-repetitive surge current tolerance for 8.3 ms half-sine, critical for inrush protection |
| VF @ 1 A | ≤1.0 V - forward voltage drop determining conduction loss and thermal dissipation in linear rectifiers |
| IR @ 25°C | ≤5 µA - reverse leakage current at rated VR, indicating low standby power loss in off-state |
| TJ Range | –55°C to +150°C - operational junction temperature window supporting wide industrial ambient conditions |
| CJ | 10 pF - junction capacitance at 1 MHz/4 V, limiting suitability to ≤10 kHz rectification, not RF use |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4004-T | Same VRRM (400 V), IF (1 A), and DO-41 package; manufactured by ON Semiconductor; slightly higher VF (1.1 V max) | Identical functional role in AC/DC rectification; validated in automotive-grade power modules | Select when requiring AEC-Q200 qualified sourcing or legacy design continuity with ON Semi footprint |
| RS1M | 400 V VRRM, 1 A IF, but faster recovery time (~500 ns vs. >2 µs); DO-41 package; higher IR (10 µA @ 25°C) | Better suited for higher-frequency flyback snubbers; less ideal for pure line-frequency rectification due to increased leakage | Choose for mixed-signal systems needing marginally improved switching behavior without layout change |
Compared with 1N4004-T and RS1M, the 1N4004G-K offers lower forward voltage and tighter reverse leakage at 25°C, making it optimal for cost-sensitive, thermally constrained, line-frequency rectifier applications where ultrafast recovery is unnecessary.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the 1N4004G-K?
The 1N4004G-K has a VRRM rating of 400 V, meaning it can reliably block up to 400 V of reverse voltage in repetitive AC waveforms without breakdown. This value is specified per the Taiwan Semiconductor datasheet Version B2104 and is confirmed across all official test conditions at 25°C ambient.
Does the 1N4004G-K meet RoHS and halogen-free requirements?
Yes, the 1N4004G-K is RoHS compliant and halogen-free per IEC 61249-2-21. The device uses green molding compound and pure tin-plated leads, satisfying both environmental directives and solderability standards (J-STD-002), as documented in the Taiwan Semiconductor product specification.
What is the forward voltage drop of the 1N4004G-K at 1 A forward current?
The 1N4004G-K exhibits a maximum forward voltage (VF) of 1.0 V at 1 A and 25°C junction temperature, measured under pulse conditions (PW = 0.3 ms). This low VF contributes to reduced conduction loss and thermal stress in continuous-duty rectifier applications.
Can the 1N4004G-K be used in place of the 1N4007G-K?
No - the 1N4004G-K (400 V VRRM) is not a direct substitute for the 1N4007G-K (1000 V VRRM). Substitution requires verifying that the circuit's peak reverse voltage remains below 400 V; exceeding this risks catastrophic failure. Always validate reverse voltage stress margins before interchanging 1N400xG-K variants.
What is the thermal resistance (RθJA) of the 1N4004G-K in free air?
The 1N4004G-K has a junction-to-ambient thermal resistance (RθJA) of 80°C/W under natural convection conditions, as specified in the Taiwan Semiconductor thermal performance table. This value assumes standard DO-41 mounting on FR-4 PCB with no heatsink or forced airflow.
