Product details

Overview

1N4006GH from Taiwan Semiconductor is an AEC-Q101 qualified, 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 1 V max forward voltage at 1 A - used in automotive DC-DC converters and industrial power supplies.

For engineers reviewing the 1N4006GH datasheet, 1N4006GH pinout, 1N4006GH application, or 1N4006GH equivalent, key selection criteria include its DO-41 package, AEC-Q101 qualification, 800 V V_RRM, 1 V V_F @ 1 A, and 30 A I_FSM rating for reliable operation in harsh-environment rectification.

Technical Context

The 1N4006GH is a single-die, PN-junction rectifier with glass-passivated chip construction ensuring high reliability and moisture resistance. Its thermal resistance R_θJA is 80 °C/W, and it operates across -55 °C to +150 °C junction temperature range.

It delivers low forward voltage drop (≤1 V @ 1 A, 25 °C), low reverse leakage (≤5 µA @ 25 °C, ≤100 µA @ 125 °C), and junction capacitance of 10 pF at 4 V reverse bias and 1 MHz - optimized for general-purpose AC/DC and switching-mode rectification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - maximum non-repetitive reverse voltage the diode blocks without breakdown
I_F	1 A continuous - average forward current rating under specified thermal conditions
I_FSM	30 A - peak surge current tolerance for 8.3 ms half-sine wave, critical for inrush handling
V_F @ 1 A	≤1 V - forward voltage drop determining conduction loss and thermal load in power stages
T_J Range	-55 °C to +150 °C - operational junction temperature window supporting automotive under-hood use
R_θJA	80 °C/W - thermal resistance from junction to ambient, defining heatsinking requirements at 1 A
C_J	10 pF @ 4 V, 1 MHz - junction capacitance affecting high-frequency switching behavior and EMI

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R06	Fast recovery (t_rr = 75 ns), higher V_F (~1.3 V), same 1 A / 600 V rating	Better suited for high-frequency SMPS (>100 kHz); less ideal for low-cost linear or low-frequency designs	Choose STTH1R06 when reducing switching loss outweighs V_F penalty and layout supports faster diode ringing control
ON Semi 1N4006G	Same electrical specs and DO-41 package, but not AEC-Q101 qualified	Limited to commercial/industrial use; unsuitable for automotive qualification programs	Select 1N4006G only for cost-sensitive non-automotive applications where AEC-Q101 is not mandated

Compared with STTH1R06 and 1N4006G, the 1N4006GH uniquely combines automotive qualification, industry-standard 1 A/800 V ratings, and low-cost DO-41 packaging - making it optimal for cost-constrained, thermally demanding, and qualification-required rectification roles.

FAQ

What is the peak repetitive reverse voltage rating of the 1N4006GH?

The 1N4006GH has a repetitive peak reverse voltage (V_RRM) rating of 800 V. This value defines the maximum reverse-bias voltage the diode can block repeatedly without avalanche breakdown. It is validated per Taiwan Semiconductor's P2104 specification and applies across the full operating temperature range. The 1N4006GH must not be subjected to reverse voltages exceeding this rating in continuous or repetitive operation.

Is the 1N4006GH AEC-Q101 qualified, and what does that mean for design use?

Yes, the 1N4006GH is explicitly AEC-Q101 qualified, as confirmed by its "H" suffix and Taiwan Semiconductor's documentation. This means it has passed stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing - validating suitability for automotive electronic modules. Designers may use the 1N4006GH in engine control, body electronics, and ADAS systems without additional qualification effort.

What is the forward voltage drop of the 1N4006GH at rated current?

The 1N4006GH exhibits a maximum forward voltage (V_F) of 1.0 V at 1 A forward current and 25 °C junction temperature, per the manufacturer's electrical specifications. This value is measured under pulsed conditions (0.3 ms pulse width) to minimize self-heating. At elevated temperatures or higher currents, V_F decreases slightly due to negative temperature coefficient of silicon diodes.

Does the 1N4006GH have a defined junction-to-ambient thermal resistance?

Yes, the 1N4006GH has a typical junction-to-ambient thermal resistance (R_θJA) of 80 °C/W when mounted on a standard FR-4 PCB with minimal copper area. This value assumes natural convection cooling and is critical for calculating junction temperature rise under 1 A DC load. For sustained operation near maximum ratings, thermal derating per the forward current derating curve in the datasheet is required.

What packaging options are available for the 1N4006GH?

The 1N4006GH is supplied in DO-204AL (DO-41) package format, available in 5,000-unit tape-and-reel (ordering code 1N4006GH) and 3,000-unit ammo box (1N4006GHA0G) configurations. Both variants feature pure tin-plated leads compliant with J-STD-002 solderability standards and meet JESD201 Class 2 whisker resistance requirements.
