Product details

Overview

1N4006L-T from Diodes Incorporated is a general-purpose silicon rectifier diode in DO-41 package, rated for 800 V peak repetitive reverse voltage and 1.0 A average forward rectified current at +75°C ambient, with 1.0 V forward voltage drop at 1.0 A, used in AC/DC power supply front-end rectification for industrial adapters and low-cost consumer power supplies.

For engineers reviewing the 1N4006L-T datasheet, 1N4006L-T pinout, 1N4006L-T application, or 1N4006L-T equivalent, key selection criteria include peak reverse voltage margin, surge current capability (30 A), thermal resistance (100 K/W), junction capacitance (8 pF), and RoHS-compliant tin-plated leads for lead-free assembly.

Technical Context

This axial-leaded diode uses a diffused PN junction to achieve low forward voltage and stable reverse blocking. Its 800 V V_RRM supports 420 V RMS input lines with safety margin, while the 30 A non-repetitive surge rating handles inrush currents in unregulated transformer-based supplies.

Thermal performance is defined by 100 K/W junction-to-ambient resistance under standard mounting (leads held at ambient 9.5 mm from case), and reverse leakage remains ≤50 µA at +100°C - critical for standby power integrity in offline converters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - blocks 800 V peak reverse voltage, enabling use with 420 V RMS mains inputs with 1.9× safety margin
I_O	1.0 A @ +75°C - continuous DC output current rating under derated ambient conditions
V_F	1.0 V @ 1.0 A - forward voltage drop directly impacts conduction loss and thermal rise in linear rectifiers
I_FSM	30 A - single half-sine surge rating at 8.3 ms, sufficient for capacitor-input filter inrush limiting
R_θJA	100 K/W - junction-to-ambient thermal resistance defines heatsinking requirements for sustained load
C_j	8 pF @ 4 V, 1 MHz - low junction capacitance minimizes switching noise and EMI in 50/60 Hz rectification

Pinout & Package

DO-41 molded plastic package with axial leads; cathode identified by a painted band on the body. Leads are bright tin-plated, solderable per MIL-STD-202 Method 208, and compliant with UL 94V-0 flammability rating.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to AC source or transformer secondary during positive half-cycle conduction
Cathode	Forward current exit point	Marked with band; connects to positive rail of DC output or smoothing capacitor anode

Key Features

Feature	Design Value
Diffused junction construction	Enables robust surge handling (30 A) and stable long-term reverse leakage behavior
Lead-free, RoHS-compliant finish	Bright tin plating ensures compatibility with Pb-free reflow and wave soldering processes
UL 94V-0 rated encapsulation	Molded plastic case meets flame-retardant safety requirement for Class II power supplies
Moisture sensitivity Level 1	No bake preconditioning required before PCB assembly - simplifies manufacturing flow

Applications

AC/DC Wall Adapters

Industrial Control Power Supplies

Use Scenario: Low-cost 12 V/1 A offline adapter for HVAC sensors and PLC I/O modules.

IC Role / Device Role / Timing Role: Primary rectifier converting 230 V AC mains to pulsating DC before bulk capacitor filtering.

Use Value: 800 V V_RRM provides margin against line surges; 1.0 V V_F limits conduction loss to <1.0 W at full load.

Use Scenario: Auxiliary 5 V bias supply in motor drive gate driver boards.

IC Role / Device Role / Timing Role: Half-wave rectifier feeding linear regulator for isolated logic supply.

Use Value: 30 A I_FSM withstands transformer saturation events; DO-41 axial form enables through-hole reliability in high-vibration environments.

Consumer Audio Power Stages

LED Lamp Driver Circuits

Use Scenario: Rectification stage in Class-D amplifier auxiliary supply.

IC Role / Device Role / Timing Role: Input rectifier in unregulated transformer-coupled supply powering op-amps and comparators.

Use Value: 8 pF C_j suppresses high-frequency ringing; 100 K/W R_θJA allows natural convection cooling without heatsink.

Use Scenario: Bridge rectifier leg in non-isolated LED tube drivers (with three other 1N4006L-T).

IC Role / Device Role / Timing Role: One quadrant of full-wave bridge converting AC line to DC for constant-current LED regulation.

Use Value: Cathode band polarity marking ensures correct bridge orientation; 50 µA max IR at +100°C maintains low standby leakage in enclosed fixtures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4006G	Same electrical specs; green marking ink instead of black, identical DO-41 package and tin plating	No functional difference; used interchangeably in same board designs	Select when color-coding or legacy BOM alignment requires G-suffix variant
S1J	1.0 A / 600 V, smaller SMD DO-204AL (SMA) package, 0.85 V V_F, 35 A I_FSM	Requires PCB redesign for surface-mount; higher surge rating but lower V_RRM	Choose for space-constrained designs where 600 V margin suffices and automated assembly is preferred

Compared with 1N4006L-T, 1N4006G offers identical performance in same package with minor marking variation, while S1J trades 200 V reverse voltage headroom for SMT compatibility and slightly lower forward drop - making it suitable only where layout and safety margin allow.

FAQ

What is the maximum operating temperature for 1N4006L-T?

The 1N4006L-T has a specified operating and storage temperature range of −65°C to +150°C. Its maximum junction temperature is +150°C, and its average forward current rating drops to 1.0 A only when ambient temperature is maintained at +75°C with leads held at ambient 9.5 mm from the case - exceeding this ambient requires thermal derating per Figure 1 in the datasheet.

Is 1N4006L-T suitable for high-frequency switching applications?

No - the 1N4006L-T is a general-purpose, slow-recovery rectifier with no specified reverse recovery time (t_rr). Its 8 pF junction capacitance and diffused junction design make it appropriate for 50/60 Hz line-frequency rectification only. For SMPS or high-frequency inverters, fast-recovery or Schottky diodes with defined t_rr must be used instead.

Does 1N4006L-T meet RoHS and REACH requirements?

Yes - the 1N4006L-T features lead-free, RoHS-compliant bright tin-plated leads and complies with EU Directive 2002/95/EC (RoHS), including all applicable exemptions. It also meets REACH SVHC requirements as confirmed in Diodes Incorporated's material declarations and is rated UL 94V-0 for flammability.

Can 1N4006L-T replace 1N4007 in existing designs?

Only if the circuit's peak reverse voltage does not exceed 800 V. The 1N4007 is rated for 1000 V V_RRM, while the 1N4006L-T is rated for 800 V - a 200 V reduction. Substitution is acceptable in 230 V AC systems with adequate safety margin but not in 380 V AC or surge-prone industrial environments where 1000 V rating is relied upon.
