Product details
Overview
1N5407G from Taiwan Semiconductor is a glass-passivated standard silicon rectifier diode rated for 3A average forward current and 800V repetitive peak reverse voltage, with 125A surge capability and 1.0V max forward voltage at 3A, used in DC-DC converters and switching-mode inverters.
For engineers reviewing the 1N5407G datasheet, 1N5407G pinout, 1N5407G application, or 1N5407G equivalent, key selection criteria include VRRM=800V, IF=3A, VF≤1.0V @3A, IFSM=125A, and DO-201AD package compatibility with high-reliability industrial power supplies.
Technical Context
This single-die, axial-leaded rectifier features a glass-passivated PN junction enabling stable operation up to 150°C junction temperature and low leakage (IR ≤5 µA @25°C, ≤100 µA @125°C). Its DO-201AD package delivers RθJA = 45°C/W and RθJC = 15°C/W for effective thermal management in compact power stages.
The device supports high-efficiency operation via low forward voltage drop and high surge tolerance-critical for handling transient overloads in unregulated AC/DC front-ends and flyback converter outputs without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum non-repetitive reverse voltage the diode blocks without breakdown; defines usable input voltage range in rectification circuits. |
| IF(AVG) | 3 A - Continuous forward current rating; determines minimum heatsinking and trace width requirements in PCB layout. |
| IFSM | 125 A - Peak one-cycle surge current (8.3 ms half-sine); enables robustness against line transients and inrush in offline SMPS. |
| VF | ≤1.0 V @ 3A, 25°C - Forward voltage drop directly impacts conduction loss and thermal rise in high-current paths. |
| TJ(max) | +150 °C - Maximum allowable junction temperature; sets thermal design margin for ambient and power dissipation constraints. |
| RθJA | 45 °C/W - Junction-to-ambient thermal resistance; used to calculate temperature rise under given power dissipation in free-air conditions. |
Pinout & Package
Package: DO-201AD - Axial-lead, molded plastic case with cathode band marking; UL 94V-0 rated compound; pure tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary; must withstand full surge current and reverse recovery stress. |
| Cathode | Forward current exit / polarity reference | Marked by colored band; ties to output rail or switching node; defines direction of rectified current flow. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V VRRM, 3 A IF, TO-220AC package, faster recovery (~65 ns) | Designed for higher-frequency switching; requires heatsink mounting | Preferred where fast recovery reduces switching loss but 800 V margin is not required |
| 1N5408G | 1000 V VRRM, identical DO-201AD package and 3 A/125 A ratings | Same footprint and thermal profile; higher reverse voltage for ultra-wide-input designs | Select when system must tolerate >800 V transients or operate with 400 VAC inputs |
Compared with STTH3L06S and 1N5408G, the 1N5407G offers optimal balance of 800 V blocking, axial DO-201AD fit, and cost-effective standard recovery performance for general-purpose industrial rectification.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the 1N5407G?
The 1N5407G has a VRRM rating of 800 V, meaning it reliably blocks up to 800 volts of reverse voltage in repetitive AC or pulsating DC applications. This value is specified per the Taiwan Semiconductor K2105 datasheet and is critical for ensuring safe operation in 230 VAC-derived DC buses or high-voltage DC-DC inputs. Exceeding this voltage risks avalanche breakdown and permanent damage to the 1N5407G.
What is the forward voltage drop (VF) of the 1N5407G at its rated current?
The 1N5407G exhibits a maximum forward voltage drop of 1.0 V at 3 A and 25°C junction temperature, per the electrical specifications table in the official datasheet. This low VF contributes to reduced conduction losses and improved thermal performance compared to earlier 1N54xx variants. At elevated temperatures or higher currents, VF may decrease slightly due to semiconductor physics, but design margins should be based on the 1.0 V max specification for the 1N5407G.
Is the 1N5407G RoHS and halogen-free compliant?
Yes, the 1N5407G is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as confirmed in the FEATURES section of the Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0 flammability standards, and the pure tin-plated leads satisfy J-STD-002 solderability requirements. These compliance attributes make the 1N5407G suitable for environmentally regulated industrial and consumer electronics manufacturing.
What is the package type and lead configuration of the 1N5407G?
The 1N5407G uses the DO-201AD package-a standardized axial-leaded, molded plastic case with cathode polarity indicated by a colored band. It features pure tin-plated leads designed for wave or hand soldering per J-STD-002. The DO-201AD outline is mechanically compatible with common through-hole footprints and supports manual or automated assembly processes for the 1N5407G.
Does the 1N5407G have automotive qualification?
The base 1N5407G is not AEC-Q101 qualified, but Taiwan Semiconductor offers an AEC-Q101-qualified variant identified by the "H" suffix (e.g., 1N5407GH). This version undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and electrostatic discharge-to meet automotive reliability requirements. For non-automotive industrial use, the standard 1N5407G remains fully suitable, while the 1N5407GH is recommended where automotive-grade validation is mandatory.
