Product details
Overview
1N5400GHR0G from Taiwan Semiconductor is a glass-passivated standard silicon rectifier diode in DO-201AD package, rated for 3 A average forward current, 50 V repetitive peak reverse voltage (VRRM), and 125 A non-repetitive surge current (IFSM), used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the 1N5400GHR0G datasheet, 1N5400GHR0G pinout, 1N5400GHR0G application, or 1N5400GHR0G equivalent, key selection criteria include verified VRRM = 50 V, IF = 3 A, VF ≤ 1.1 V @ 3 A, RθJA = 45 °C/W, and DO-201AD mechanical compatibility with high-reliability industrial power designs.
Technical Context
This single-die standard rectifier operates as a unidirectional current-conducting device with glass-passivated junction for moisture and contamination resistance. It supports continuous conduction at up to 150 °C junction temperature and withstands 8.3 ms half-sine surge events up to 125 A without degradation.
Its low forward voltage drop (≤1.1 V at 3 A, 25 °C) reduces conduction losses in high-current linear and switching power stages, while its 25 pF junction capacitance minimizes high-frequency switching noise coupling in flyback and buck converter outputs.

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 1N5400G | VF max = 1.2 V @ 3 A (vs. 1.1 V); same DO-201AD package and 50 V VRRM | Marginally higher conduction loss in thermally constrained layouts | Select when cross-manufacturer second sourcing is required and 0.1 V VF difference is acceptable |
| Vishay 1N5400-E3/54 | Same electrical specs; lead finish is matte tin (not pure tin), JESD 201 Class 1 whisker rating | Suitable for less demanding industrial environments where Class 2 whisker testing not mandated | Choose for cost-sensitive consumer-grade power supplies with relaxed reliability requirements |
Compared with ON Semiconductor 1N5400G and Vishay 1N5400-E3/54, the 1N5400GHR0G offers the lowest specified forward voltage (≤1.1 V), Class 2 whisker compliance, and pure tin plating-making it preferred for high-reliability, thermally dense, or automotive-qualified designs where long-term solder joint integrity is critical.

FAQ
What is the maximum junction temperature rating for the 1N5400GHR0G?
The 1N5400GHR0G has a maximum junction temperature (TJ) of +150 °C, validated across its full operating range from –55 °C to +150 °C. This rating allows reliable operation in sealed industrial enclosures and under-hood automotive environments. The 1N5400GHR0G achieves this via glass-passivated junction construction and low thermal resistance (RθJC = 15 °C/W), enabling effective heat transfer to the PCB or heatsink.
Is the 1N5400GHR0G AEC-Q101 qualified?
Yes, the "H" in the 1N5400GHR0G part number indicates AEC-Q101 qualification. This means the 1N5400GHR0G has undergone stress testing per the AEC-Q101 standard for discrete semiconductors-including HTGB, HTRB, and temperature cycling-to validate reliability for automotive power electronics applications such as body control modules and infotainment power supplies.
What does the "R0G" suffix mean in 1N5400GHR0G?
The "R0G" suffix in 1N5400GHR0G denotes tape-and-reel packaging: "R" = reel, "0" = standard orientation, "G" = green (halogen-free) compound. This distinguishes it from ammo box (A0G) or non-halogen-free variants. The 1N5400GHR0G is supplied in 1,250-piece reels compatible with automated SMT placement equipment using axial lead feeders.
How does the forward voltage of the 1N5400GHR0G compare to other 1N540xG series diodes?
The 1N5400GHR0G has a maximum forward voltage (VF) of 1.1 V at 3 A and 25 °C-lower than the 1.2 V typical for 1N5401G–1N5408G variants rated above 100 V VRRM. This reflects optimized doping and junction design for the 50 V grade, making the 1N5400GHR0G especially efficient in low-voltage, high-current rectification where conduction loss dominates thermal design.
Can the 1N5400GHR0G replace older 1N5400 variants in existing designs?
Yes, the 1N5400GHR0G is a direct form-fit-function replacement for legacy 1N5400 diodes in DO-201AD packages, with identical pinout, dimensions, and electrical ratings. Its glass passivation, pure tin plating, and halogen-free molding compound improve long-term reliability and environmental compliance over earlier versions-no PCB or layout changes are needed when upgrading to the 1N5400GHR0G.
