Product details
Overview
1N4001G from Taiwan Semiconductor is a glass-passivated silicon standard rectifier diode rated for 1 A average forward current and 50 V repetitive peak reverse voltage, with 30 A surge capability and 1 V max forward voltage at 1 A - used in low-voltage DC-DC converters and general-purpose AC/DC front-end rectification.
For engineers reviewing the 1N4001G datasheet, 1N4001G pinout, 1N4001G application, or 1N4001G equivalent, key selection criteria include its DO-41 package compatibility, 150°C junction temperature rating, AEC-Q101 qualification option, thermal resistance (80°C/W), and verified 5 µA reverse leakage at 25°C.
Technical Context
This single-die, unidirectional PN-junction rectifier operates as a line-frequency or low-frequency switching rectifier with fixed polarity indicated by cathode band. Its glass-passivated junction ensures stable performance under humidity and thermal cycling, while pure tin-plated leads meet J-STD-002 solderability standards.
The device exhibits 10 pF junction capacitance at 1 MHz and 4 V reverse bias, enabling predictable behavior in low-speed power conversion circuits. Its 80°C/W junction-to-ambient thermal resistance requires appropriate PCB copper area for sustained 1 A operation at elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Average Forward Current) | 1 A - supports continuous rectification in low-power adapters and auxiliary supplies |
| VRRM (Repetitive Peak Reverse Voltage) | 50 V - suitable for ≤35 V RMS input circuits, e.g., 24 VAC transformer secondaries |
| IFSM (Surge Forward Current) | 30 A - withstands inrush during cold-start of capacitive-input rectifiers |
| VF (Max Forward Voltage) | 1 V @ 1 A, 25°C - limits conduction loss to ≤1 W per diode at full load |
| IR (Reverse Current) | 5 µA @ 25°C - ensures minimal leakage in high-impedance hold-up or sensing paths |
| RθJA (Thermal Resistance) | 80 °C/W - requires ≥1 cm² copper pour for safe 1 A operation at 70°C ambient |
| CJ (Junction Capacitance) | 10 pF @ 1 MHz, 4 V - negligible effect on 50/60 Hz or <100 kHz switching waveforms |
Pinout & Package
Package: DO-204AL (DO-41) - axial-leaded, epoxy-molded case with cathode band marking; UL 94V-0 rated compound; 0.33 g mass; lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry node | Connects to AC source or transformer secondary side; must handle full surge current path |
| Cathode (banded end) | Forward current exit node / reverse blocking terminal | Connects to filter capacitor or load; polarity marking prevents reverse installation in PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable reverse leakage and long-term reliability in humid industrial environments |
| AEC-Q101 qualified version available | Supports automotive body electronics applications requiring stress-tested components |
| Low VF (≤1 V @ 1 A) | Reduces conduction losses by ~20% vs. legacy 1N4001 variants with higher VF |
| Junction temperature range: –55°C to +150°C | Permits operation in sealed enclosures or engine-bay-adjacent locations without derating |
| Pure tin-plated leads | Ensures consistent solder wetting and eliminates whisker risk per JESD201 Class 2 |

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 1N4001FS | Same DO-41 package; VF = 1.1 V max @ 1 A; IR = 5 µA @ 25°C; not AEC-Q101 qualified | Lacks automotive qualification; identical thermal and surge ratings | Select when AEC-Q101 is not required and ON Semi sourcing is preferred |
| Diodes Incorporated P600F-005 | DO-204AL package; 50 V VRRM; 1 A IF; VF = 1.1 V max; IR = 5 µA @ 25°C; 50 A IFSM | Higher surge rating enables use in higher-inrush designs; same footprint | Choose for enhanced surge margin in motor-control auxiliary supplies |
Compared with 1N4001G, the 1N4001FS offers identical form factor but no automotive qualification, while P600F-005 provides 67% higher surge current tolerance with no PCB change - both serve as functional alternatives where specific stress or qualification needs differ.

FAQ
What is the maximum junction temperature rating for the 1N4001G?
The 1N4001G has a maximum junction temperature (TJ) rating of +150°C, allowing reliable operation in enclosed or high-ambient-temperature environments such as industrial control cabinets or automotive under-hood locations. This rating is maintained across the full storage temperature range of –55°C to +150°C, supporting wide deployment flexibility without thermal derating below 70°C ambient when mounted on adequate copper area.
Is the 1N4001G RoHS and halogen-free compliant?
Yes, the 1N4001G is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability standards, and its pure tin-plated leads satisfy J-STD-002 solderability requirements - making it suitable for global consumer, industrial, and automotive electronics where environmental compliance is mandatory.
Does the 1N4001G have AEC-Q101 qualification?
The base 1N4001G is not AEC-Q101 qualified, but Taiwan Semiconductor offers an AEC-Q101-qualified variant identified by the "H" suffix (e.g., 1N4001GH). That version undergoes additional stress testing for automotive applications, while maintaining identical electrical and thermal specifications and DO-41 packaging - enabling drop-in qualification upgrades where needed.
What is the forward voltage drop of the 1N4001G at rated current?
The 1N4001G has a maximum forward voltage (VF) of 1.0 V at 1 A forward current and 25°C junction temperature, measured under pulse conditions (PW = 0.3 ms). This low VF reduces conduction losses and thermal loading compared to older rectifier families, supporting efficient operation in compact, unventilated power supplies.
How does the 1N4001G compare to the 1N4007G in terms of reverse voltage rating?
The 1N4001G is rated for 50 V repetitive peak reverse voltage (VRRM), whereas the 1N4007G is rated for 1000 V VRRM - a 20× difference. Both share identical forward current (1 A), surge (30 A), thermal (80°C/W), and packaging (DO-41) specs. Select 1N4001G only for ≤35 V RMS input circuits; using it in higher-voltage applications risks catastrophic reverse breakdown.
