Product details
Overview
1N5406G from Taiwan Semiconductor is a glass-passivated standard silicon rectifier diode rated for 3 A average forward current and 600 V repetitive peak reverse voltage, with 125 A surge capability and 1.0 V max forward voltage at 3 A - used in DC-DC converters, switching inverters, and industrial power supplies.
For engineers reviewing the 1N5406G datasheet, 1N5406G pinout, 1N5406G application, or 1N5406G equivalent, key selection criteria include VRRM=600 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 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 thermal resistance RθJA = 45 °C/W supports convection-cooled PCB mounting in space-constrained power stages.
The device delivers high surge robustness (8.3 ms half-sine) and low capacitance (CJ = 25 pF @ 4 V), making it suitable for medium-frequency switching applications where reverse recovery behavior and EMI control are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum non-repetitive reverse voltage the diode blocks without breakdown |
| IF(AV) | 3 A - continuous average forward current under specified thermal conditions |
| IFSM | 125 A - peak non-repetitive surge current survivable for one 8.3 ms half-sine cycle |
| VF | ≤1.0 V @ 3 A, 25 °C - forward voltage drop defining conduction loss in power stage |
| TJ(max) | +150 °C - maximum allowable junction temperature for reliable long-term operation |
| RθJA | 45 °C/W - thermal resistance from junction to ambient, guiding heatsinking requirements |
Pinout & Package
Package: DO-201AD - axial-lead, molded plastic case with cathode band marking; RoHS-compliant, halogen-free, UL 94V-0 rated compound; tin-plated leads per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential side of AC input or switch node in flyback/flywheel configurations |
| Cathode (Lead 2) | Forward current exit / reverse blocking terminal | Marked by band; connects to output rail or positive bus; withstands up to 600 V reverse bias |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable leakage performance and humidity resistance over lifetime in industrial environments |
| Low VF (≤1.0 V @ 3 A) | Reduces conduction losses by ~15% vs. legacy 1N54xx variants with VF ≥1.1 V at same current |
| 125 A IFSM rating | Supports robust startup and fault tolerance in unregulated or loosely regulated SMPS inputs |
| DO-201AD mechanical standard | Ensures compatibility with automated through-hole insertion and wave soldering tooling |
Applications
| AC/DC Front-End Rectification | DC-DC Converter Output Stage |
|---|---|
Use Scenario: Converting 115/230 VAC mains to unregulated DC bus in offline SMPS. IC Role / Device Role / Timing Role: Primary-side rectifier conducting full-wave or bridge configuration. Use Value: 600 V VRRM safely handles line surges and reflected spikes; 125 A IFSM absorbs inrush during cold start. | Use Scenario: Freewheeling or output rectification in 12–48 V isolated DC-DC modules. IC Role / Device Role / Timing Role: Secondary-side unidirectional current path in forward or flyback topologies. Use Value: Low VF minimizes power loss at 3 A load; DO-201AD footprint fits compact board layouts. |
| Switching Inverter Power Stage | Industrial Motor Drive Snubber |
Use Scenario: DC link rectification in 3-phase VFD front-ends or UPS battery charging circuits. IC Role / Device Role / Timing Role: High-current, medium-voltage rectifier handling intermittent overload. Use Value: 150 °C TJ(max) and 45 °C/W RθJA allow operation without forced air in enclosed enclosures. | Use Scenario: Clamping transient energy across IGBTs or relays in motor control boards. IC Role / Device Role / Timing Role: Passive snubber diode absorbing inductive kickback. Use Value: Fast recovery characteristics (inherent in standard rectifier design) and 25 pF CJ limit capacitive loading on gate drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V, 3 A, fast recovery (trr ≈ 50 ns), TO-220AC package | Higher switching speed enables higher-frequency operation but requires heatsink mounting | Preferred when trr < 100 ns is required and board space allows TO-220 footprint |
| ON Semi MUR460 | 600 V, 4 A, ultrafast recovery (trr ≈ 35 ns), DO-201AD package | Lower VF (~0.95 V) and faster recovery, but higher cost and tighter IR spec (≤3.0 µA) | Selected for improved efficiency in high-duty-cycle converters where leakage must be minimized |
Compared with STTH3L06S and MUR460, the 1N5406G offers lowest cost and proven reliability in 50–120 kHz applications where fast recovery is not critical - its DO-201AD form factor and 1.0 V VF balance thermal performance, layout simplicity, and BOM cost.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the 1N5406G?
The 1N5406G has a VRRM rating of 600 V, meaning it can reliably block up to 600 volts of reverse-biased voltage in repetitive operation without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version K2105) and applies across the full operating temperature range.
What is the forward voltage drop of the 1N5406G at rated current?
The 1N5406G exhibits a maximum forward voltage (VF) of 1.0 V at 3 A forward current and 25 °C junction temperature, as specified in the Electrical Specifications table. This value reflects typical conduction loss under standard test conditions and is lower than earlier 1N5400G–1N5401G variants (1.1 V).
Does the 1N5406G have AEC-Q101 qualification?
The base 1N5406G is not AEC-Q101 qualified; however, the variant 1N5406GH (with "H" suffix) is explicitly listed as AEC-Q101 qualified in the Ordering Information section. The 1N5406G itself meets industrial reliability standards including JESD201 Class 2 whisker testing and RoHS/halogen-free compliance.
What package type does the 1N5406G use, and what are its key mechanical properties?
The 1N5406G uses the DO-201AD package: an axial-leaded, molded plastic case with cathode band marking, UL 94V-0 flammability rating, pure tin-plated leads compliant with J-STD-002, and approximate weight of 1.20 g. Polarity is unambiguously indicated by the cathode band.
How does the 1N5406G compare to the 1N5408G in terms of voltage rating and application scope?
The 1N5406G is rated for 600 V VRRM, while the 1N5408G is rated for 1000 V - making the latter suitable for higher-line applications like 380 VAC industrial systems. Both share identical IF=3 A, IFSM=125 A, VF≤1.0 V, and DO-201AD packaging, so they are interchangeable only where voltage margin permits.
