Product details
Overview
1N5400G R0G from Taiwan Semiconductor is a glass-passivated standard silicon rectifier diode rated for 3 A average forward current and 50 V repetitive peak reverse voltage in a DO-201AD package, featuring low forward voltage (1.1 V at 3 A, 25°C), high surge capability (125 A, 8.3 ms), and AEC-Q101 qualification option - used in DC/DC converters and switching-mode power supplies.
For engineers reviewing the 1N5400G R0G datasheet, 1N5400G R0G pinout, 1N5400G R0G application, or 1N5400G R0G equivalent, key selection criteria include verified VRRM = 50 V, IF = 3 A, IFSM = 125 A, TJMAX = 150°C, and DO-201AD mechanical compatibility with industrial and automotive-grade thermal and reliability requirements.
Technical Context
This discrete rectifier operates as a unidirectional current-conducting device with a single p-n junction, optimized for line-frequency and medium-frequency switching applications. Its glass-passivated chip ensures stable reverse leakage (<5 µA at 25°C) and robust surge immunity under repetitive half-sine stress.
The DO-201AD package delivers RθJA = 45°C/W and RθJC = 15°C/W, enabling reliable thermal management in compact PCB layouts without forced airflow. Junction temperature range spans −55°C to +150°C, supporting operation in harsh ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (avg) | 3 A - supports continuous output current in 36–48 V input DC/DC stages |
| VRRM | 50 V - blocks up to 50 V reverse voltage in low-voltage rectification circuits |
| IFSM | 125 A - withstands short-duration inrush/surge events in SMPS startup |
| VF | 1.1 V @ 3 A, 25°C - minimizes conduction loss and heat generation at full load |
| TJMAX | +150°C - enables operation in sealed enclosures or high-ambient industrial settings |
| RθJA | 45°C/W - defines thermal rise above ambient per watt dissipated in free-air conditions |
| CJ | 25 pF @ 1 MHz, 4 V - limits high-frequency switching noise coupling in flyback snubbers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | Fast recovery (trr = 75 ns), same IF/VRRM, TO-220AC package | Lower switching loss in >20 kHz topologies; requires heatsink mounting | Select when operating frequency exceeds 10 kHz or EMI reduction is critical |
| ON Semi MUR460 | Ultrafast recovery (trr = 50 ns), 4 A IF, 600 V VRRM, DO-201AD | Higher voltage margin and faster switching, but higher VF (1.7 V) | Prefer where 600 V isolation or reduced ringing is required, accepting 0.6 V higher drop |
Compared with STTH3L06S and MUR460, the 1N5400G R0G offers lowest cost and simplest board-level integration in 50 V, ≤10 kHz applications, while trading off speed for ruggedness and thermal simplicity in DO-201AD.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the 1N5400G R0G?
The 1N5400G R0G has a VRRM of 50 V, meaning it reliably blocks up to 50 V of reverse voltage in repetitive operation. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version K2105), and applies across the full operating temperature range (−55°C to +150°C).
Is the 1N5400G R0G RoHS and halogen-free compliant?
Yes, the 1N5400G R0G meets RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The device uses green molding compound and pure tin-plated leads, both verified in the Mechanical Data and Ordering Information sections of the Taiwan Semiconductor datasheet.
Does the 1N5400G R0G have AEC-Q101 qualification?
The base 1N5400G R0G is not AEC-Q101 qualified; however, the AEC-Q101 variant is designated as 1N5400GH (with "H" suffix). Per Taiwan Semiconductor's ordering information, only parts marked with "H" undergo full AEC-Q101 stress testing - the R0G suffix indicates tape-and-reel packaging, not qualification status.
What is the forward voltage (VF) of the 1N5400G R0G at rated current?
The 1N5400G R0G exhibits a maximum forward voltage of 1.1 V at IF = 3 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects, ensuring repeatability in design calculations.
What package type does the 1N5400G R0G use, and what are its key mechanical properties?
The 1N5400G R0G uses the DO-201AD axial package, featuring UL 94V-0 flammability-rated epoxy, pure tin-plated leads compliant with J-STD-002, and JESD 201 Class 2 whisker resistance. Its weight is approximately 1.20 g, and polarity is marked by a visible cathode band on the body.
