Product details
Overview
1N5407-B from Diodes Incorporated is a 3.0A, 800V peak repetitive reverse voltage general-purpose silicon rectifier diode in DO-201AD package, featuring 1.0V forward voltage at 3.0A, 200A non-repetitive surge capability, and low 10μA reverse leakage at 25°C - used in AC/DC power supplies, battery chargers, and DC motor control circuits.
For engineers reviewing the 1N5407-B datasheet, 1N5407-B pinout, 1N5407-B application, or 1N5407-B equivalent, key selection criteria include rated blocking voltage (800V), thermal resistance (15°C/W), surge robustness (200A @ 8.3ms), junction temperature range (–65°C to +150°C), and DO-201AD mechanical compatibility with high-current PCB layouts.
Technical Context
This axial-lead rectifier operates in single-phase, half-wave configurations with resistive or inductive loads at 60Hz; capacitive loads require 20% current derating. Its diffused junction enables stable forward conduction and low IRM across temperature.
Thermal performance is defined under standardized lead-mounting conditions (9.5mm from case to ambient), and total capacitance (25pF @ 1MHz, 4V reverse) supports moderate-speed switching in line-frequency applications - not intended for high-frequency rectification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - maximum peak reverse voltage the diode blocks without breakdown in repetitive operation |
| IO @ TA=105°C | 3.0 A - average forward current sustainable with leads held at ambient at 9.5 mm from case |
| VFM @ IF=3.0A | 1.0 V - forward voltage drop determining conduction loss and thermal dissipation at full rated load |
| IFSM @ 8.3ms | 200 A - non-repetitive surge current handling capability during power-up or fault transients |
| IRM @ VR=800V, 25°C | 10 μA - reverse leakage defining off-state power loss and isolation integrity in high-impedance circuits |
| RθJA | 15 °C/W - junction-to-ambient thermal resistance under specified mounting conditions, critical for heatsinkless designs |
| Tj/TSTG Range | –65°C to +150°C - operational and storage temperature envelope supporting industrial and automotive under-hood environments |
Pinout & Package
Package: DO-201AD molded plastic case (UL 94V-0), axial-leaded, cathode identified by band marking, 1.1g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to AC input or transformer secondary; must handle full 3A RMS and surge currents |
| Cathode (Lead 2, banded end) | Forward current exit / reverse voltage blocking terminal | Connected to filter capacitor or load; polarity-sensitive for correct DC polarity and reverse voltage rating utilization |
Key Features
| Feature | Design Value |
|---|---|
| Diffused junction construction | Enables uniform current distribution and stable VFM/IRM over lifetime and temperature |
| 200A surge rating (8.3ms) | Withstands inrush currents in transformer-coupled supplies without degradation |
| Low 10μA IRM at 25°C | Minimizes standby power loss in always-on power rails and improves voltage hold-up |
| DO-201AD mechanical standardization | Ensures compatibility with legacy through-hole tooling, wave solder fixtures, and IPC-7351 footprints |
Applications
| AC/DC Power Supply Input Stage | Battery Charger Rectification |
|---|---|
Use Scenario: Full-wave or half-wave rectification of 50/60Hz mains-derived AC before bulk capacitance filtering. IC Role / Device Role / Timing Role: Discrete power diode performing unidirectional current conversion; no timing function. Use Value: 800V VRRM safely accommodates 230VAC line peaks with margin; 3A IO supports up to ~35W output in non-PFC designs. | Use Scenario: Converting transformer-isolated AC to DC for NiCd/NiMH or lead-acid battery charging circuits. IC Role / Device Role / Timing Role: Main rectifying element in constant-voltage or tapered-current charge topologies. Use Value: Low VFM (1.0V) reduces heat generation during continuous charging; 200A IFSM tolerates transformer saturation surges. |
| DC Motor Drive Freewheeling | Industrial Control Power Rails |
Use Scenario: Flyback diode across brushed DC motor windings to clamp inductive kickback during PWM switching. IC Role / Device Role / Timing Role: Passive snubber diode providing low-impedance path for stored inductive energy. Use Value: 200A surge rating absorbs high-energy transients; DO-201AD leadframe handles repeated 3A commutation currents. | Use Scenario: Auxiliary power supply for PLC I/O modules, relay drivers, or sensor interface circuitry operating from 24VAC or 115VAC inputs. IC Role / Device Role / Timing Role: Primary rectifier in compact, cost-optimized linear or capacitive-dropper power supplies. Use Value: –65°C to +150°C rating ensures reliability in unventilated enclosures; RoHS-compliant tin plating supports automated assembly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5407G (ON Semiconductor) | Same VRRM (800V), IO (3A), and DO-201AD package; slightly higher VFM (1.2V typ. @ 3A) | Identical use in line-frequency rectification; higher VFM increases conduction loss by ~0.6W at full load | Select when ON Semi's qualification or lot traceability is required; verify thermal margin with higher VFM |
| RS3M (Fairchild/ON Semi) | Same 3A/800V rating but in smaller DO-15 package; RθJA = 25°C/W vs. 15°C/W | Suitable only where board space is constrained and thermal management includes heatsinking or airflow | Prefer for space-constrained designs with active cooling; avoid in sealed, convection-limited enclosures |
Compared with 1N5407G and RS3M, the 1N5407-B offers superior thermal resistance (15°C/W) and lower forward drop (1.0V), making it optimal for thermally demanding, high-reliability line-frequency rectification where DO-201AD footprint is acceptable.

FAQ
Is the 1N5407-B RoHS compliant?
Yes, the 1N5407-B features a lead-free finish and is RoHS compliant per EU Directive 2002/95/EC (Rev. 13.2.2003), with exemptions applied for glass and high-temperature solder per Annex Notes 5 and 7. Tin-plated leads meet MIL-STD-202, Method 208 solderability requirements.
Can the 1N5407-B be used in high-frequency switching applications?
No - the 1N5407-B is optimized for 50/60Hz line-frequency rectification. Its 25pF junction capacitance and relatively slow reverse recovery (not specified in the datasheet, but typical of general-purpose rectifiers) make it unsuitable for SMPS or >1kHz switching; use fast recovery or Schottky diodes instead.
What is the derating requirement for capacitive-load applications?
For capacitive-input filter loads, the average forward current rating must be reduced by 20% - limiting IO to 2.4A at TA = 105°C. This accounts for higher peak currents drawn during capacitor charging, which increase junction temperature and stress beyond resistive/inductive load assumptions.
Does the 1N5407-B have a specified reverse recovery time (trr)?
No - the official Diodes Incorporated datasheet DS28007 Rev. 8–3 does not specify reverse recovery time. The device is classified as a general-purpose rectifier, not a fast-recovery type; trr is typically >2μs and unsuitable for high-speed switching. Designers requiring trr data should select a documented fast-recovery alternative.
