Product details
Overview
1N5407G-K from Taiwan Semiconductor is a glass-passivated standard silicon rectifier diode rated for 3 A average forward current and 800 V repetitive peak reverse voltage, with 125 A surge capability and 1.0 V max forward voltage at 3 A and 25°C junction temperature, used in DC-DC converters and switching-mode inverters.
For engineers reviewing the 1N5407G-K datasheet, 1N5407G-K pinout, 1N5407G-K application, or 1N5407G-K equivalent, key selection criteria include VRRM=800 V, IF=3 A, VF≤1.0 V @ 3 A, IFSM=125 A, and DO-201AD package compatibility with high-reliability power conversion designs.
Technical Context
This single-die, axial-leaded rectifier operates as a unidirectional current-conducting device with cathode-band polarity indication, optimized for line-frequency and medium-frequency switching applications up to 60 Hz duty cycles. Its glass-passivated junction ensures stable leakage performance across -55°C to +150°C operating range.
Thermal design relies on RθJA=45°C/W and RθJC=15°C/W values, enabling reliable operation under continuous 3 A load with appropriate PCB copper area or heatsinking. Reverse leakage remains ≤5 µA at 25°C and ≤100 µA at 125°C under rated VR.

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5407G | Same electrical specs and DO-201AD package; differs only in packaging format (tape & reel vs. ammo box) | No functional difference; identical use in PCB assembly and thermal management | Select 1N5407G-K for automated pick-and-place; choose 1N5407G for manual or low-volume prototyping |
| STTH308S | Higher VF (~1.15 V @ 3 A), faster recovery (trr ≈ 500 ns), TO-220AC package, 800 V VRRM | Better suited for higher-frequency switching (>20 kHz); requires heatsink mounting | Choose STTH308S when reducing switching losses or operating above 10 kHz; retain 1N5407G-K for cost-sensitive 50/60 Hz or <5 kHz designs |
Compared with 1N5407G and STTH308S, the 1N5407G-K offers optimal balance of low VF, proven reliability, and axial-leaded DO-201AD compatibility-making it preferred for cost-driven, thermally constrained, and line-frequency rectification where fast recovery is unnecessary.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the 1N5407G-K?
The 1N5407G-K has a VRRM rating of 800 V, meaning it can reliably block up to 800 volts of reverse voltage in repetitive operation without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version C2105), and provides sufficient margin for 230 VAC mains-derived circuits where peak voltage reaches ~325 V.
What is the forward voltage drop (VF) specification for the 1N5407G-K at rated current?
The 1N5407G-K exhibits a maximum forward voltage of 1.0 V at 3 A forward current and 25°C junction temperature, per the Electrical Specifications table. This VF value is measured under pulsed conditions (PW = 0.3 ms) and defines conduction loss in power stages-lower than earlier 1N5400–5401 variants but consistent with 1N5402G-K through 1N5408G-K family members.
Does the 1N5407G-K have RoHS and halogen-free compliance?
Yes, the 1N5407G-K is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. The "G" suffix denotes green compound molding, and the "-K" suffix indicates tape-and-reel packaging compliant with J-STD-002 solderability and JESD 201 Class 1A whisker testing.
What package type does the 1N5407G-K use, and what are its mechanical highlights?
The 1N5407G-K uses the DO-201AD package: an axial-leaded, molded plastic case rated UL 94V-0 for flammability. Key mechanical features include pure tin-plated leads (solderable per J-STD-002), cathode-band polarity marking, and a typical weight of 1.20 g. Dimensions and outline are fully specified in the Package Outline Dimensions section of the datasheet.
How does the 1N5407G-K compare to the 1N5408G-K in terms of voltage rating and application suitability?
The 1N5407G-K is rated for 800 V VRRM, while the 1N5408G-K is rated for 1000 V. Both share identical IF=3 A, IFSM=125 A, VF≤1.0 V, and DO-201AD packaging. Choose 1N5407G-K for 230 VAC-derived supplies with margin; select 1N5408G-K only when system-level transients or 400 VAC inputs demand higher blocking voltage.
