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 automated through-hole assembly.

Technical Context

This discrete rectifier operates as a unidirectional current-conducting device with a single p-n junction, optimized for low forward voltage drop and high surge tolerance in line-frequency and medium-frequency switching power supplies.

Its glass-passivated chip junction ensures stable reverse leakage (<5 µA at 25 °C, <100 µA at 125 °C) and robust thermal performance (R_θJA = 80 °C/W), enabling reliable operation in ambient temperatures up to 75 °C at full rated current.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - maximum non-repetitive reverse voltage the diode blocks without breakdown
I_F	1 A - continuous average forward current rating at T_A = 75 °C (derated above)
I_FSM	30 A - peak non-repetitive surge current (8.3 ms half-sine) for transient overload handling
V_F max	1.0 V @ 1 A, 25 °C - forward voltage drop defining conduction loss in power stage
T_J range	–55 to +150 °C - operational junction temperature window supporting industrial and automotive environments
C_J	10 pF @ 1 MHz, 4 V - junction capacitance affecting high-frequency switching behavior and EMI

Pinout & Package

Package: DO-204AL (DO-41), axial-leaded, glass-passivated, RoHS-compliant, halogen-free molding compound (UL 94V-0), pure tin-plated leads.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor 1N4005	V_RRM = 600 V, I_F = 1 A, same DO-41 package; VF max = 1.1 V (vs. 1.0 V for 1N4005G)	Identical functional role; slightly higher conduction loss at full load	Preferred where legacy ON Semi sourcing is required; verify VF impact on thermal design
STMicroelectronics TS4005	V_RRM = 600 V, I_F = 1 A, DO-41; IR = 5 µA @ 25 °C (same), but TJ max = 175 °C (vs. 150 °C)	Higher junction temperature rating enables tighter derating in confined spaces	Select when extended thermal margin is critical; otherwise functionally interchangeable

Compared with ON Semiconductor 1N4005 and STMicroelectronics TS4005, the 1N4005G offers identical 600 V/1 A ratings and DO-41 fit, with lowest V_F (1.0 V) among the three-reducing conduction loss-and AEC-Q101 qualification option for automotive-grade variants.

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 defined per JEDEC standards and verified under specified test conditions. The 1N4005G is part of the 1N4001G–1N4007G family, where "005" directly indicates the 600 V grade. Designers must ensure operating reverse voltage stays below this value with appropriate safety margin.

Does the 1N4005G support automotive applications?

The base 1N4005G is not AEC-Q101 qualified, but Taiwan Semiconductor offers an AEC-Q101 variant marked as 1N4005GH (with "H" suffix). The 1N4005G itself meets industrial temperature and reliability requirements (–55 to +150 °C, glass passivation, JESD201 Class 2 whisker testing), making it suitable for non-safety-critical automotive auxiliary systems when validated per end-application requirements.

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 and 25 °C, measured under pulsed conditions (PW = 0.3 ms). At higher junction temperatures (e.g., 125 °C), V_F decreases slightly due to semiconductor physics. This low V_F reduces conduction loss compared to older 1N400x variants, improving efficiency in 1 A power paths where thermal management is constrained.

Is the 1N4005G available in tape-and-reel packaging?

Yes-the 1N4005G is offered in tape-and-reel format as 1N4005GH (AEC-Q101 qualified, 5,000 pcs/reel) and standard 1N4005G (5,000 pcs/reel). The "A0G" suffix (as in 1N4005G A0G) denotes ammo box packaging (3,000 pcs/box). Tape-and-reel versions support automated pick-and-place for hybrid or through-hole assembly lines requiring reel-fed feeding.

How does the thermal resistance (R_θJA) of the 1N4005G affect PCB layout?

The 1N4005G has a typical R_θJA of 80 °C/W, meaning junction temperature rises 80 °C above ambient per watt of dissipated power. At 1 A and 1.0 V V_F, power dissipation is ~1 W-resulting in ~80 °C rise. To maintain T_J ≤ 150 °C, ambient must stay ≤ 70 °C unless additional copper pour or airflow is added. Layout should maximize copper area on both anode and cathode pads to improve heat spreading.
