Product details
Overview
1N4006G-K from Taiwan Semiconductor is a single-die, glass-passivated standard silicon rectifier diode rated for 1 A average forward current and 800 V repetitive peak reverse voltage, with 30 A surge capability and 1 V max forward voltage at 1 A - used in AC/DC front-end rectification for industrial power supplies and switching inverters.
For engineers reviewing the 1N4006G-K datasheet, 1N4006G-K pinout, 1N4006G-K application, or 1N4006G-K equivalent, key selection criteria include verified VRRM = 800 V, IF = 1 A, IFSM = 30 A, TJ = –55°C to +150°C, and DO-41 package compatibility with legacy through-hole layouts.
Technical Context
This device operates as a unidirectional power rectifier with a PN junction optimized for low conduction loss and high transient surge tolerance. Its glass passivation ensures stable surface leakage performance across temperature and humidity stress.
The 1N4006G-K exhibits 10 pF junction capacitance at 4 V reverse bias and 1 MHz, enabling predictable behavior in 50/60 Hz and low-frequency SMPS input stages. Reverse leakage remains ≤5 µA at 25°C and ≤100 µA at 125°C under rated VR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - supports rectification of 560 VRMS AC inputs (e.g., 400 VAC industrial lines with safety margin) |
| IF | 1 A continuous - suitable for low-to-medium power DC outputs up to ~12 W at 12 V with adequate heatsinking |
| IFSM | 30 A (8.3 ms half-sine) - withstands inrush surges from transformer-coupled or capacitive-input supplies |
| VF max | 1.0 V @ 1 A, 25°C - limits conduction loss to ≤1 W per diode in linear operation |
| TJ range | –55°C to +150°C - enables deployment in sealed enclosures or high-ambient industrial environments |
| RθJA | 80°C/W - requires ≥1.2 cm² copper pad for safe 1 A operation at 70°C ambient without forced air |
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 JESD201 Class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry point | Connects to AC source or transformer secondary low-side during positive half-cycle |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connects to output filter capacitor positive rail; blocks 800 V reverse during negative half-cycle |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Prevents moisture-induced surface leakage and improves long-term reliability in humid environments |
| Low VF (≤1.0 V) | Reduces power dissipation by ~20% vs. older 1N400x variants with VF up to 1.1 V |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for green manufacturing |
| UL 94V-0 molding compound | Ensures flame-retardant enclosure integrity during overtemperature fault conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4006-T | VRRM = 800 V, same IF/IFSM, but plastic passivated (not glass) junction | Slightly higher IR at elevated temperature; less robust in high-humidity environments | Select 1N4006G-K when long-term reliability in humid or outdoor-rated enclosures is required |
| STTH1R08 | Fast recovery (trr ≈ 150 ns), VF = 1.15 V, same VRRM/IF | Better suited for high-frequency SMPS (>20 kHz); higher conduction loss at 50/60 Hz | Choose STTH1R08 only if reducing switching losses in high-frequency converters outweighs added cost and VF penalty |
Compared with 1N4006-T and STTH1R08, the 1N4006G-K delivers optimal balance of surge robustness, low-cost manufacturability, and environmental resilience for line-frequency rectification - making it preferred for cost-sensitive industrial power entry designs where speed is not critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the 1N4006G-K?
The 1N4006G-K has a specified VRRM of 800 V, confirmed in the Absolute Maximum Ratings table of Taiwan Semiconductor's B2104 datasheet. This rating defines the highest instantaneous reverse voltage the diode can block repeatedly without breakdown under normal operating conditions, making it suitable for 560 VRMS AC inputs with safety margin.
Does the 1N4006G-K have a glass-passivated junction, and why does it matter?
Yes, the 1N4006G-K features a glass-passivated chip junction, explicitly stated in its FEATURES section. This construction significantly reduces surface leakage current and enhances long-term stability in humid or thermally cycled environments compared to plastic-passivated alternatives like the 1N4006-T, directly improving field reliability in industrial enclosures.
What is the forward voltage drop (VF) of the 1N4006G-K at rated current?
The 1N4006G-K has a maximum forward voltage of 1.0 V at IF = 1 A and TJ = 25°C, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss - actual VF is typically lower at lower currents or elevated temperatures.
Is the 1N4006G-K RoHS and halogen-free compliant?
Yes, the 1N4006G-K is RoHS compliant and halogen-free per IEC 61249-2-21, as documented in the FEATURES section of the official datasheet. The "G" suffix denotes green compound, and the device carries full compliance documentation for use in environmentally regulated industrial and commercial equipment.
What package type does the 1N4006G-K use, and how is polarity indicated?
The 1N4006G-K uses the DO-204AL (DO-41) axial package with pure tin-plated leads. Polarity is clearly marked by a cathode band on the banded end of the body - this band must be oriented toward the positive output side of the circuit to ensure correct rectification and reverse blocking function in the 1N4006G-K.
