Product details
Overview
1N4006-T from Diodes Incorporated is a general-purpose silicon rectifier diode in DO-41 package, rated for 1.0A average forward current and 800V peak repetitive reverse voltage, with 1.0V forward voltage at 1.0A and 30A non-repetitive surge capability-commonly used in AC/DC power supply input stages, battery charger front-ends, and DC power rail protection circuits.
For engineers reviewing the 1N4006-T datasheet, 1N4006-T pinout, 1N4006-T application, or 1N4006-T equivalent, key selection criteria include its 800V blocking rating, thermal resistance (100°C/W), low reverse leakage (5.0μA @ 25°C), junction capacitance (8pF), and DO-41 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
The 1N4006-T implements a diffused P-N junction optimized for high-surge tolerance and stable DC blocking in line-frequency rectification. Its 800V VRRM enables use in 400–560V RMS AC mains-derived supplies, while the 100°C/W RθJA defines thermal derating above +75°C ambient.
It exhibits low forward voltage (1.0V @ 1.0A) and minimal reverse leakage (5.0μA @ 25°C, 50μA @ 100°C), supporting efficient energy conversion and reliable hold-off in unregulated power supplies where ripple filtering follows rectification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 800 V - supports rectification of up to 560V RMS AC inputs without breakdown |
| Avg Forward Current | 1.0 A - sustains continuous DC output in low-to-medium power SMPS and linear supplies |
| Forward Voltage | 1.0 V @ 1.0A - limits conduction loss to ≤1W at full rated current |
| Surge Current | 30 A (8.3ms half-sine) - withstands inrush during cold-start of capacitive-input filters |
| Reverse Leakage | 5.0 μA @ 25°C - ensures minimal standby power loss in off-state blocking |
| Junction Capacitance | 8 pF @ 4V - negligible impact on 50/60Hz rectification; no RF switching limitation |
| Thermal Resistance | 100 °C/W - requires ≥9.5mm lead length or heatsinking for sustained 1A operation above +75°C |
Pinout & Package
Package: DO-41 molded plastic case (UL 94V-0), axial leads with cathode band marking; weight ≈0.30 g; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary; must handle full surge current path |
| Cathode | Forward current exit / reverse-blocking terminal | Connected to filter capacitor or load; marked by band; carries DC output polarity |
Key Features
| Feature | Design Value |
|---|---|
| Diffused junction construction | Enables robust surge handling (30A) without localized thermal runaway |
| Low forward voltage drop | Reduces conduction loss to ≤1W at 1A, easing thermal design in compact enclosures |

Applications
| AC/DC Power Supply Input Stage | Battery Charger Front-End |
|---|---|
Use Scenario: Full-wave bridge rectification of 230V AC mains feeding bulk capacitor input. IC Role / Device Role / Timing Role: Discrete rectifier diode providing unidirectional current flow and DC polarity establishment. Use Value: 800V VRRM ensures margin against line surges; 30A IFSM absorbs capacitor inrush without failure. | Use Scenario: Half-wave rectification in low-cost 12V lead-acid battery chargers with transformer isolation. IC Role / Device Role / Timing Role: Unidirectional current gate between transformer secondary and charging circuit. Use Value: 1.0V VF minimizes voltage drop across diode, preserving charging efficiency at 1A output. |
| DC Power Rail Protection | Industrial Control Signal Conditioning |
Use Scenario: Reverse-polarity protection on +24V DC input rails of PLC I/O modules. IC Role / Device Role / Timing Role: Series blocking diode preventing damage from accidental negative connection. Use Value: Low 5.0μA reverse leakage avoids significant standby current drain in always-on systems. | Use Scenario: Clamping and level-shifting of 0–10V analog sensor signals in motor drive feedback loops. IC Role / Device Role / Timing Role: Passive signal limiter using forward conduction and reverse blocking thresholds. Use Value: Predictable 1.0V forward drop and 8pF junction capacitance avoid distortion or phase shift at <1kHz signal frequencies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4006G (ON Semiconductor) | Identical 800V VRRM, 1.0A IO, DO-41 package; same forward voltage and surge rating | No functional difference; qualified to AEC-Q101 for automotive-grade reliability | Select when automotive qualification or alternate sourcing is required |
| RS1M (Fairchild/ON Semi) | Same 1.0A/800V ratings but faster recovery time (~500ns vs. ~2μs); slightly higher VF (1.1V) | Better suited for higher-frequency rectification (e.g., 20kHz SMPS secondaries); not optimized for 50/60Hz | Prefer for switch-mode outputs where reverse recovery matters; avoid in pure line-frequency designs due to cost premium |
Compared with 1N4006G, the 1N4006-T offers identical electrical performance with standard industrial qualification; versus RS1M, it trades slower recovery for lower cost and proven stability in legacy 50/60Hz applications.

FAQ
Is the 1N4006-T suitable for use in automotive applications?
No-the 1N4006-T is not AEC-Q101 qualified. While it meets industrial temperature and reliability standards, Diodes explicitly states that automotive-grade versions (e.g., 1N4006Q) require PPAP documentation and IATF 16949 manufacturing. Use only after formal qualification review for vehicle systems.
What is the maximum operating temperature for continuous 1.0A current?
The 1N4006-T supports 1.0A average forward current only up to +75°C ambient temperature, per derating curve. At higher temperatures, current must be reduced linearly-e.g., to ~0.7A at +100°C-with leads maintained at 9.5mm length from case for thermal measurement reference.
Can the 1N4006-T replace the 1N4007 in a 1000V-rated design?
No-1N4006-T has 800V peak reverse voltage versus 1000V for 1N4007. Substituting it in a design relying on 1000V blocking margin risks catastrophic failure under transient overvoltage or elevated line conditions. Always verify VRRM match before interchange.
Does the 1N4006-T have a specified reverse recovery time?
No-reverse recovery time (trr) is not characterized in the DS28002 datasheet. The device is optimized for 50/60Hz rectification, not high-frequency switching. For trr-critical applications, select fast-recovery alternatives like RS1M or UF4006 with published recovery specs.
