Product details
Overview
1N4005G-K from Taiwan Semiconductor is a glass-passivated silicon standard rectifier diode rated for 1 A average forward current and 600 V repetitive peak reverse voltage, with 30 A surge capability and 1 V max forward voltage at 1 A, used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the 1N4005G-K datasheet, 1N4005G-K pinout, 1N4005G-K application, or 1N4005G-K equivalent, key selection criteria include VRRM=600 V, IFSM=30 A, VF≤1 V @ 1 A, TJ(max)=150 °C, and DO-41 package compatibility with through-hole PCB layouts.
Technical Context
The 1N4005G-K is a single-die, PN-junction silicon rectifier optimized for general-purpose AC-to-DC conversion. Its glass-passivated junction ensures stable leakage performance across temperature, while its 80 °C/W junction-to-ambient thermal resistance supports operation up to 150 °C junction temperature under natural convection.
It delivers low forward voltage drop (≤1 V at 1 A) and ultra-low reverse leakage (≤5 µA at 25 °C, ≤100 µA at 125 °C), enabling high efficiency in low-frequency rectification circuits where switching speed is not critical. Junction capacitance is specified at 10 pF @ 1 MHz, 4 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum non-repetitive reverse voltage the diode blocks without breakdown; defines usable input AC voltage range in bridge or half-wave rectifiers. |
| IF(AV) | 1 A - Continuous average forward current rating; determines maximum DC output current capability in linear or low-frequency switched supplies. |
| IFSM | 30 A - Peak non-repetitive surge current (8.3 ms sine half-wave); enables robustness against inrush and transient overloads during startup. |
| VF | ≤1 V @ 1 A, 25 °C - Forward voltage drop directly impacts conduction loss and thermal dissipation in rectifier stage design. |
| IR | ≤5 µA @ 600 V, 25 °C - Reverse leakage current affects standby power loss and voltage hold-off integrity in high-impedance circuits. |
| TJ(max) | 150 °C - Maximum allowable junction temperature; sets thermal derating limits and heatsinking requirements for sustained operation. |
| RθJA | 80 °C/W - Thermal resistance from junction to ambient; used to calculate temperature rise under given power dissipation in free-air conditions. |
Pinout & Package
Package: DO-204AL (DO-41), axial-leaded, epoxy-molded case with cathode band marking. Leads are pure tin-plated, J-STD-002 solderable, and meet JESD 201 Class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to AC source or transformer secondary side; polarity must align with circuit's forward-bias requirement. |
| Cathode | Forward current exit terminal | Marked by visible band; connects to load or filter capacitor; defines direction of DC output polarity. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable IR and long-term reliability under humidity and thermal cycling, critical for industrial and consumer power supplies. |
| Low VF (≤1 V @ 1 A) | Reduces conduction losses and self-heating, allowing higher efficiency and smaller heatsink requirements in 1 A-class rectification. |
| High IFSM (30 A) | Withstands repeated cold-start surges in offline SMPS and adapter designs without degradation or failure. |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and environmental directives, supporting green manufacturing and export compliance. |
| UL 94V-0 molding compound | Provides flame-retardant encapsulation essential for safety-certified power adapters and ITE equipment. |
Applications
| AC/DC Power Adapters | Industrial DC Power Supplies |
|---|---|
Use Scenario: Rectifying 50/60 Hz AC mains or transformer secondary output into unregulated DC for wall adapters and embedded system inputs. IC Role / Device Role / Timing Role: Standard rectifier diode in single-phase half-wave or full-bridge configuration. Use Value: 600 V VRRM safely handles 230 VAC input with margin; 1 A IF supports typical 5–12 V/500 mA–1 A output ratings. | Use Scenario: Converting AC line voltage to DC bus for motor drives, PLC power rails, or sensor interface modules. IC Role / Device Role / Timing Role: Input-stage rectifier in unregulated linear or buck-derived supplies. Use Value: 30 A IFSM accommodates high inrush currents from large bulk capacitors; 150 °C TJ(max) supports operation in enclosed, high-ambient environments. |
| Switching Mode Inverters | DC-DC Converter Outputs |
Use Scenario: Output rectification in low-frequency auxiliary windings or snubber clamp paths in flyback or forward converters. IC Role / Device Role / Timing Role: Freewheeling or clamp diode handling low-duty-cycle, high-voltage transients. Use Value: 600 V rating covers reflected voltage spikes; low IR minimizes standby loss in always-on control circuitry. | Use Scenario: Secondary-side rectification in isolated DC-DC modules for telecom or industrial backplanes. IC Role / Device Role / Timing Role: Synchronous or non-synchronous rectifier in low-speed, cost-sensitive isolated outputs. Use Value: DO-41 package enables manual assembly and rework; 1 V VF balances efficiency and BOM cost vs. Schottky alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4005-T | VRRM=600 V, same IF/IFSM, but plastic passivation instead of glass; slightly higher IR at elevated temperature. | Less suitable for high-humidity or extended-life industrial deployments where long-term leakage stability is critical. | Prefer 1N4005G-K where reliability under thermal/humidity stress is prioritized. |
| STTH1R06 | Fast recovery (trr ≈ 150 ns), VF ≈ 1.15 V @ 1 A, same VRRM and package; higher switching loss but lower EMI in higher-frequency designs. | Used in quasi-resonant or higher-frequency SMPS where reverse recovery behavior affects efficiency and noise. | Select STTH1R06 only when fast recovery is required; otherwise, 1N4005G-K offers lower cost and adequate performance at 50/60 Hz. |
Compared with 1N4005-T and STTH1R06, the 1N4005G-K provides optimal balance of cost, reliability, and low-frequency rectification performance-its glass passivation and proven 150 °C operation make it preferred for mainstream AC/DC front-end use where speed is not critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the 1N4005G-K?
The 1N4005G-K has a VRRM rating of 600 V, meaning it can reliably block up to 600 V of reverse voltage in repetitive AC or pulsating DC applications without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet Version B2104 and defines the upper limit for safe operation in rectifier circuits fed from 230 VAC mains with appropriate safety margin.
Is the 1N4005G-K suitable for surface-mount assembly?
No, the 1N4005G-K uses a DO-204AL (DO-41) axial-leaded package and is designed exclusively for through-hole mounting. It is not compatible with reflow or wave soldering processes intended for SMD components. For surface-mount equivalents, consider SMA or SMB packaged rectifiers such as M1, M2, or ES1B–ES1J series-but note those differ in VRRM, VF, and thermal performance versus the 1N4005G-K.
What does the 'G' suffix in 1N4005G-K signify?
The 'G' in 1N4005G-K indicates green (halogen-free) molding compound compliant with IEC 61249-2-21, and the 'K' denotes tape-and-reel packaging (5,000 units per reel). This marking follows Taiwan Semiconductor's standardized ordering code format where 'G' reflects environmental compliance and 'K' specifies packaging type-both confirmed in the Ordering Information section of the 1N4001G-K–1N4007G-K datasheet.
How does the 1N4005G-K compare to the 1N4007G-K in terms of forward voltage?
The 1N4005G-K and 1N4007G-K share identical forward voltage specifications: ≤1 V at 1 A and 25 °C. Their VF performance is functionally interchangeable because both belong to the same die family and process; only VRRM differs (600 V vs. 1000 V). Therefore, substituting 1N4005G-K for 1N4007G-K is acceptable only if the circuit's peak reverse voltage remains below 600 V.
Can the 1N4005G-K be used in high-frequency switching applications?
The 1N4005G-K is not recommended for high-frequency switching applications (e.g., >20 kHz) due to its relatively slow reverse recovery time (not explicitly specified but typical of standard rectifiers: ~2–4 µs). Its design prioritizes low VF and surge robustness at line frequency-not fast switching. For such applications, fast recovery or ultrafast diodes like STTH1R06 or UF4005 should be selected instead of the 1N4005G-K.
