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, switching inverters, and general-purpose AC/DC front-end rectification.

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

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 robustness in line-frequency and SMPS rectification stages. Its glass-passivated chip junction ensures stable leakage performance across temperature.

Thermal resistance R_θJA is 80°C/W in free-air conditions, and junction capacitance is 10 pF at 1 MHz and 4.0 V reverse bias - supporting predictable switching behavior in non-ultrafast applications where recovery time is not critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - maximum repetitive reverse voltage the diode blocks without breakdown in continuous operation
I_F	1 A - average forward rectified current under specified thermal conditions (T_A ≤ 55°C)
I_FSM	30 A - non-repetitive peak surge current (8.3 ms half-sine) the device withstands during transient overloads
V_F (max)	1.0 V @ I_F = 1 A, T_J = 25°C - defines conduction loss and thermal dissipation in linear rectifier stages
T_J range	–55°C to +150°C - operational junction temperature window enabling use in industrial and automotive-adjacent environments
C_J	10 pF @ 1 MHz, V_R = 4.0 V - junction capacitance affecting high-frequency noise coupling and snubber design

Pinout & Package

Package: DO-204AL (DO-41), axial-leaded, glass-passivated silicon die in molded epoxy case with cathode band marking. Leads are pure tin-plated and solderable per J-STD-002.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor 1N4005	V_RRM = 600 V, I_F = 1 A, same DO-41 package; VF ≈ 1.1 V (max) - slightly higher conduction loss	No AEC-Q101 variant offered; RoHS status requires verification per batch	Select when cost sensitivity outweighs automotive qualification needs
Vishay 1N4005-E3/54	V_RRM = 600 V, I_F = 1 A, DO-41; IR = 5 µA @ 25°C - identical leakage spec, but no halogen-free declaration	Not certified halogen-free per IEC 61249-2-21; UL 94V-0 rating confirmed	Prefer for legacy designs requiring Vishay's traceability and long-term availability

Compared with ON Semiconductor 1N4005 and Vishay 1N4005-E3/54, the 1N4005G offers verified halogen-free construction, AEC-Q101 qualification path, and tighter V_F guarantee - making it suitable for new industrial and automotive-adjacent designs requiring compliance and consistency.

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 reliably blocks up to 600 volts of reverse-biased voltage in repetitive operation. This value is defined per the Taiwan Semiconductor P2104 datasheet and distinguishes the 1N4005G from lower-voltage variants like the 1N4004G (400 V) and higher-voltage 1N4006G (800 V). The 1N4005G must not be operated beyond this rating to avoid junction breakdown.

Is the 1N4005G suitable for automotive applications?

The base 1N4005G is not AEC-Q101 qualified, but the pin- and electrically identical 1N4005GH variant is explicitly qualified per AEC-Q101. For automotive use, specify the "H" suffix. The 1N4005G itself meets RoHS and halogen-free standards and operates from –55°C to +150°C, but formal automotive qualification applies only to the GH version.

What is the forward voltage drop (V_F) specification for the 1N4005G?

The 1N4005G has a maximum forward voltage of 1.0 V at I_F = 1 A and T_J = 25°C, measured under pulsed conditions (PW = 0.3 ms). This V_F value directly determines conduction losses in rectifier circuits. At elevated temperatures or lower currents, V_F decreases slightly - typical values range from 0.85 V to 0.95 V under nominal operating conditions.

Does the 1N4005G have a specified junction-to-ambient thermal resistance?

Yes, the 1N4005G has a typical junction-to-ambient thermal resistance (R_θJA) of 80°C/W under free-air conditions, as stated in the Taiwan Semiconductor P2104 datasheet. This value assumes no heatsinking and is used to estimate junction temperature rise: T_J = T_A + (P_LOSS × R_θJA). Derating curves in the datasheet show allowable I_F reduction above 55°C ambient.

What packaging options are available for the 1N4005G?

The 1N4005G is supplied in DO-204AL (DO-41) package with two standard packing formats: 5,000 units per tape-and-reel (ordering code 1N4005G) and 3,000 units per ammo box (ordering code 1N4005G A0G). Both use pure tin-plated leads compliant with J-STD-002 and meet JESD201 Class 2 whisker testing requirements.
