Product details
Overview
1N5407G from Taiwan Semiconductor is a glass-passivated, single-die standard rectifier diode rated for 3 A average forward current and 800 V repetitive peak reverse voltage (VRRM), with 125 A surge capability and 1.0 V max forward voltage at 3 A - 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 = 800 V, IF = 3 A, VF ≤ 1.0 V @ 3 A, thermal resistance RθJA = 45 °C/W, and DO-201AD package compatibility.
Technical Context
This device operates as a unidirectional power rectifier with a PN junction fabricated using glass passivation for enhanced moisture and contamination resistance. Its 150 °C maximum junction temperature and 125 A non-repetitive surge rating support robust operation in transient-heavy industrial power supplies.
The DO-201AD package provides axial-leaded mechanical stability and meets UL 94V-0 flammability requirements. Cathode polarity is marked by a visible band, and terminals are pure tin-plated per J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - blocks up to 800 V reverse voltage without breakdown in continuous operation |
| IF | 3 A - maximum average forward current under specified thermal conditions |
| IFSM | 125 A - withstands 8.3 ms half-sine surge, enabling protection against line transients |
| VF | ≤1.0 V @ 3 A, 25°C - low conduction loss improves efficiency in high-current rectification |
| TJ max | 150 °C - allows operation in high-ambient environments such as enclosed power enclosures |
| RθJA | 45 °C/W - defines thermal rise from junction to ambient; requires adequate PCB copper area for heat dissipation |
| CJ | 25 pF @ 1 MHz, 4 V - limits high-frequency switching noise and affects snubber design |
Pinout & Package
DO-201AD axial-leaded package with cathode indicated by a painted band; leads are pure tin-plated and solderable per J-STD-002. Weight ≈1.20 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry point | Connected to AC input or transformer secondary side prior to rectification |
| Cathode (banded end) | Forward current exit / reverse blocking node | Connects to output filter capacitor or load; blocks reverse voltage during negative half-cycle |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Prevents moisture ingress and surface leakage, improving long-term reliability in humid environments |
| AEC-Q101 qualified option available (1N5407GH) | Validated for automotive-grade stress testing including temperature cycling and HTRB |
| UL 94V-0 molding compound | Self-extinguishing encapsulant required for safety-critical power supply designs |

|---|---|
Use Scenario: Step-down conversion in isolated flyback or forward topologies with 24–48 V input. IC Role / Device Role / Timing Role: Output rectifier converting high-frequency transformer secondary AC to regulated DC. Use Value: Low VF (≤1.0 V) reduces conduction loss; 125 A IFSM handles startup surges without failure. | Use Scenario: Grid-tied solar microinverters converting panel DC to 50/60 Hz AC. IC Role / Device Role / Timing Role: Bridge rectifier input stage or auxiliary supply rectification. Use Value: 800 V VRRM supports >600 V DC bus systems; DO-201AD enables manual assembly and field replacement. |
| Industrial Power Supply | AC Motor Drive Control |
Use Scenario: Unregulated auxiliary supply for gate drivers and logic in 3-phase motor drives. IC Role / Device Role / Timing Role: Input rectifier feeding bulk capacitor in offline SMPS. Use Value: 150 °C TJmax ensures stable operation near heatsinks; RθJA = 45 °C/W guides heatsink sizing. | Use Scenario: Snubber network rectification and DC link monitoring circuits. IC Role / Device Role / Timing Role: Signal-level rectifier in feedback path or voltage sensing divider. Use Value: 25 pF CJ minimizes capacitive coupling into sensitive analog paths; low IR (<5 µA @ 25°C) preserves measurement accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V VRRM, 3 A, TO-220AC package, 1.15 V VF @ 3 A | Higher thermal mass but larger footprint; requires mounting hardware | Preferred where higher surge margin or heatsink attachment is needed |
| ON Semi MUR460 | 600 V VRRM, 4 A, ultrafast recovery (trr = 50 ns), DO-201AD | Lower VRRM but faster switching; suited for high-frequency PFC stages | Select when reducing switching losses outweighs need for 800 V blocking |
Compared with STTH3L06S and MUR460, the 1N5407G offers the highest VRRM (800 V) in DO-201AD, making it optimal for 400–600 V AC-input rectification where space and cost constrain TO-220 use, while maintaining lower VF than many ultrafast alternatives.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the 1N5407G?
The 1N5407G has a VRRM of 800 V, verified per Taiwan Semiconductor's K2105 datasheet. This rating defines the maximum reverse voltage the diode can block repeatedly without avalanche breakdown under normal operating conditions, making it suitable for 400–600 V AC-input rectification circuits where derating is applied.
Does the 1N5407G have an AEC-Q101 qualified version?
Yes - the 1N5407GH variant is AEC-Q101 qualified and shares identical electrical specs with the 1N5407G, differing only in qualification testing and packaging code. The "H" suffix denotes full automotive stress validation, including temperature cycling, HTRB, and ESD testing per AEC-Q101 Rev D.
What is the forward voltage drop (VF) of the 1N5407G at rated current?
The 1N5407G exhibits a maximum forward voltage of 1.0 V at 3 A and 25°C junction temperature, per the Electrical Specifications table in the official datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss for thermal design calculations.
Which package type does the 1N5407G use, and what are its mechanical highlights?
The 1N5407G uses the DO-201AD axial-leaded package. Key mechanical features include UL 94V-0 compliant molding compound, pure tin-plated leads meeting J-STD-002 solderability, cathode polarity marked by a visible band, and compliance with JESD 201 Class 2 whisker resistance for long-term reliability.
How does the 1N5407G compare to the 1N5408G in terms of voltage rating and application scope?
The 1N5407G is rated for 800 V VRRM, while the 1N5408G is rated for 1000 V. Both share identical IF = 3 A, IFSM = 125 A, and DO-201AD packaging. The 1N5407G is typically selected for 400–600 V AC-input systems where 1000 V margin is unnecessary, offering tighter cost control without sacrificing surge or thermal performance.
