Product details

Overview

1N4006G from Taiwan Semiconductor is a glass-passivated silicon standard rectifier diode rated for 1 A average forward current and 800 V repetitive peak reverse voltage, with 30 A surge capability and 150 °C maximum junction temperature, used in DC-DC converters and switching inverters.

For engineers reviewing the 1N4006G datasheet, 1N4006G pinout, 1N4006G application, or 1N4006G equivalent, key selection criteria include V_RRM = 800 V, I_F = 1 A, V_F ≤ 1.0 V at 1 A, I_R ≤ 5 µA at 25 °C, and DO-204AL (DO-41) package compatibility with through-hole PCB assembly.

Technical Context

This discrete rectifier operates as a unidirectional current-conducting device with a single p-n junction, optimized for line-frequency and medium-speed switching applications up to ~1 kHz. Its glass passivation ensures stable surface characteristics under humidity and thermal stress.

The 1N4006G exhibits low forward voltage drop (≤1.0 V @ 1 A), low reverse leakage (≤5 µA @ 25 °C), and high surge robustness (30 A, 8.3 ms half-sine), making it suitable for non-synchronous rectification in off-line power supplies and AC adapters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input voltage handling (e.g., 560 V_RMS bridge input).
I_F	1 A - Continuous average forward current; sets thermal design margin for heatsinking in linear or low-duty-cycle operation.
I_FSM	30 A - Non-repetitive surge rating; supports inrush current tolerance during cold-start of capacitive-input rectifiers.
V_F	≤1.0 V @ 1 A, 25 °C - Forward conduction loss directly impacts efficiency and junction self-heating in steady-state operation.
I_R	≤5 µA @ 25 °C - Reverse leakage determines standby power loss and voltage hold-up integrity in high-impedance circuits.
T_J max	150 °C - Maximum allowable junction temperature; constrains ambient derating per R_θJA = 80 °C/W.

Pinout & Package

Package: DO-204AL (DO-41), axial-leaded, epoxy-molded case with cathode band marking. Lead material: pure tin-plated copper, J-STD-002 solderable.

Pin/Terminal	Circuit Role	Design Meaning
Anode (unmarked end)	Forward current entry node	Connected to AC source or transformer secondary side; polarity must align with circuit's forward bias requirement.
Cathode (banded end)	Forward current exit node / reverse voltage reference	Marked by visible band; ties to positive rail in half-wave rectifier or common output in full-wave bridge configuration.

Key Features

Feature	Design Value
Glass-passivated junction	Prevents surface contamination and moisture-induced leakage drift, enabling stable long-term performance in humid environments.
RoHS & halogen-free compliance	Meets IEC 61249-2-21 and EU RoHS directives; eliminates brominated flame retardants and lead in manufacturing.
UL 94V-0 molding compound	Self-extinguishing encapsulant prevents flame propagation in overtemperature fault conditions.
JESD 201 Class 2 whisker resistance	Ensures reliability of tin-plated leads under thermal cycling, avoiding conductive filament growth that could cause short circuits.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor 1N4006	V_RRM = 800 V, I_F = 1 A, V_F ≤ 1.1 V @ 1 A - slightly higher typical forward voltage.	No AEC-Q101 option; standard industrial grade only.	Select when cost sensitivity outweighs automotive qualification needs.
Diodes Incorporated P6006	V_RRM = 800 V, I_F = 1 A, but in DO-201AD package - surface-mount, not axial.	Requires PCB redesign; unsuitable for through-hole legacy assemblies.	Choose only for new SMT designs where board space and automated assembly are priorities.

Compared with ON Semiconductor 1N4006 and Diodes Inc. P6006, the 1N4006G offers identical electrical ratings in the industry-standard DO-41 package, with optional AEC-Q101 qualification and halogen-free construction - making it preferred for automotive aftermarket and environmentally regulated industrial deployments.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the 1N4006G?

The 1N4006G has a V_RRM rating of 800 V, meaning it can block up to 800 volts of reverse-biased DC or peak AC voltage without breakdown. This value is fixed per the part number designation and confirmed in Taiwan Semiconductor's P2104 datasheet. The 1N4006G must not be operated beyond this limit to ensure reliable long-term performance.

Is the 1N4006G suitable for use in automotive applications?

Yes - an AEC-Q101 qualified variant, designated 1N4006GH, is available. While the base 1N4006G is industrial-grade, the GH suffix indicates full qualification for automotive underhood and infotainment systems. Engineers specifying the 1N4006G for automotive use should verify ordering code suffixes and consult Taiwan Semiconductor's qualification reports for the 1N4006G family.

What is the forward voltage drop (V_F) of the 1N4006G at rated current?

The 1N4006G exhibits a maximum forward voltage of 1.0 V at 1 A and 25 °C, per the Electrical Specifications table in the P2104 datasheet. This value is measured under pulsed conditions (0.3 ms pulse width) and represents worst-case conduction loss - actual V_F may be lower at reduced current or elevated temperature.

Does the 1N4006G have a specified junction-to-ambient thermal resistance?

Yes - the 1N4006G has a typical R_θJA of 80 °C/W when mounted on a standard FR-4 PCB with 0.5-inch copper traces, as stated in the Thermal Performance section of the P2104 datasheet. This value guides thermal derating: at 25 °C ambient, maximum usable I_F drops to ~0.75 A before reaching 150 °C junction temperature.

What packaging options are available for the 1N4006G?

The 1N4006G is supplied in DO-204AL (DO-41) package with two standard packing formats: 5,000 units per tape-and-reel (1N4006G or 1N4006GH) and 3,000 units per ammo box (1N4006G A0G or 1N4006GHA0G). All variants retain identical electrical and mechanical specifications - only packaging and qualification differ.
