Product details

Overview

1N4005G from Taiwan Semiconductor is a glass-passivated silicon standard rectifier diode rated for 1 A average forward current and 600 V repetitive peak reverse voltage, with 30 A surge capability and 1.0 V max forward voltage at 1 A, used in DC-DC converters and switching inverters.

For engineers reviewing the 1N4005G datasheet, 1N4005G pinout, 1N4005G application, or 1N4005G equivalent, key selection criteria include V_RRM = 600 V, I_F = 1 A, I_FSM = 30 A, T_J = –55 to +150 °C, and DO-41 package compatibility with through-hole power supply designs.

Technical Context

The 1N4005G operates as a single-die, unidirectional PN-junction rectifier with glass-passivated chip construction for enhanced moisture resistance and long-term reliability under thermal cycling. Its junction-to-ambient thermal resistance is 80 °C/W, enabling operation up to 150 °C junction temperature without forced cooling in moderate-power applications.

It exhibits low forward voltage (≤1.0 V at 1 A, 25 °C), low reverse leakage (≤5 µA at 25 °C, ≤100 µA at 125 °C), and 10 pF junction capacitance at 4 V reverse bias and 1 MHz - characteristics optimized for general-purpose AC/DC front-end rectification and freewheeling in flyback and buck-derived topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - maximum non-repetitive reverse voltage the diode blocks reliably in circuit
I_F	1 A continuous - average forward current rating defining steady-state power handling
I_FSM	30 A (8.3 ms half-sine) - surge current capacity for inrush or transient overload protection
V_F max	1.0 V @ 1 A, 25 °C - forward conduction loss directly impacting efficiency and thermal rise
T_J range	–55 to +150 °C - operational junction temperature window supporting industrial ambient conditions
C_J	10 pF @ 4 V, 1 MHz - junction capacitance affecting high-frequency switching behavior and EMI
I_R max	5 µA @ 25 °C, 600 V - reverse leakage determining off-state power loss and voltage hold capability

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4005	No green compound or halogen-free compliance; not AEC-Q101 qualified; identical electrical specs	Limited to non-automotive, non-RoHS-restricted environments	Select when cost sensitivity outweighs environmental compliance or automotive qualification
STTH1R06	Fast recovery (t_rr ≈ 150 ns), higher V_F (~1.3 V), same 600 V/1 A ratings	Better suited for high-frequency SMPS (>50 kHz); higher conduction loss at low frequency	Choose for reduced switching loss in fast-switching topologies where 1N4005G's 1.0 V V_F is less critical than t_rr

Compared with 1N4005, the 1N4005G adds RoHS/halogen-free compliance and optional AEC-Q101 qualification without altering core rectification performance; versus STTH1R06, it trades faster recovery for lower forward loss and simpler drive requirements in line-frequency or low-kHz applications.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the 1N4005G?

The 1N4005G has a V_RRM of 600 V, meaning it can block up to 600 V of reverse voltage repeatedly without breakdown. This rating is confirmed in the Absolute Maximum Ratings table of the Taiwan Semiconductor P2104 datasheet and defines the upper limit for safe operation in rectifier and clamping applications where reverse voltage transients occur.

Is the 1N4005G RoHS and halogen-free compliant?

Yes, the 1N4005G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. The "G" suffix denotes green compound and halogen-free construction, distinguishing it from legacy non-G variants like 1N4005.

What is the forward voltage drop (V_F) of the 1N4005G at rated current?

The 1N4005G has a maximum forward voltage of 1.0 V at 1 A forward current and 25 °C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss for thermal design and efficiency calculations.

Does the 1N4005G have AEC-Q101 qualification?

The base 1N4005G is not automatically AEC-Q101 qualified; however, an AEC-Q101-qualified version is available under ordering codes such as 1N4005GH (with "H" suffix). The qualification status must be verified via the specific part number ordering code, as noted in the Ordering Information section of the datasheet.

What package type does the 1N4005G use, and what are its mechanical identifiers?

The 1N4005G uses the DO-204AL (DO-41) axial package, with pure tin-plated leads, UL 94V-0 flammability-rated molding compound, and cathode polarity indicated by a visible band. Its approximate weight is 0.330 g, and it meets JESD201 Class 2 whisker testing requirements.
