Product details

Overview

1N4002G R0G from Taiwan Semiconductor is a glass-passivated silicon standard rectifier diode rated for 1 A average forward current and 100 V repetitive peak reverse voltage, with 30 A surge capability and 1 V max forward voltage at 1 A - used in AC/DC front-end rectification for power supplies and DC-DC converters.

For engineers reviewing the 1N4002G R0G datasheet, 1N4002G R0G pinout, 1N4002G R0G application, or 1N4002G R0G equivalent, key selection factors include its DO-41 package, cathode-band polarity marking, 150°C junction temperature rating, and compliance with AEC-Q101 (when ordered with 'H' suffix), RoHS, and halogen-free standards.

Technical Context

This discrete rectifier operates as a single-die, unidirectional PN-junction device with glass-passivated chip construction for enhanced moisture resistance and long-term reliability under thermal cycling. Its 80°C/W junction-to-ambient thermal resistance and 10 pF junction capacitance at 1 MHz / 4 V support stable operation in low-frequency switching and line-frequency rectification.

The 1N4002G R0G exhibits 5 µA max reverse leakage at 25°C and 100 µA at 125°C under rated reverse voltage, enabling predictable blocking performance across industrial temperature ranges without requiring active thermal derating below 150°C junction limit.

Key Specifications

ParameterValue and Actual Design Meaning
VRRM100 V - maximum non-repetitive reverse voltage the diode blocks reliably in circuit
IF(AV)1 A - continuous average forward current capability at TA = 75°C with adequate heatsinking
IFSM30 A - peak non-repetitive surge current tolerance for 8.3 ms half-sine, critical for inrush handling
VF(max)1.0 V @ 1 A, 25°C - defines conduction loss and thermal dissipation in rectifier stage
TJ(max)+150°C - maximum allowable junction temperature, sets thermal design margin for PCB layout
CJ10 pF @ 1 MHz, VR = 4 V - limits high-frequency noise coupling and switching speed in low-speed applications

Equivalent & Alternatives

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

Alternative PartTechnical DifferenceApplication DifferenceSelection Advice
ON Semiconductor 1N4002FSSame DO-41 package, identical VRRM (100 V), IF (1 A), IFSM (30 A); VF = 1.1 V max (slightly higher conduction loss)No AEC-Q101 option; RoHS-compliant but not halogen-free certifiedSelect when AEC-Q101 or halogen-free compliance is not required and ON Semi supply chain preference applies
Diodes Incorporated P6002SHigher IFSM (60 A), same VRRM/IF; DO-204AL package with tighter VF distribution (0.95 V typ)Designed for higher-reliability industrial use; no automotive qualification pathChoose for enhanced surge robustness in motor drive or solenoid control where transient immunity is critical

Compared with 1N4002G R0G, the 1N4002FS offers identical ratings but less stringent environmental compliance, while the P6002S delivers superior surge handling at the cost of slightly higher unit price and no AEC-Q101 path - making 1N4002G R0G optimal for cost-sensitive, RoHS/halogen-free, and optionally automotive-qualified designs.

FAQ

What is the maximum repetitive peak reverse voltage (VRRM) for the 1N4002G R0G?

The 1N4002G R0G has a VRRM rating of 100 V. This value represents the highest instantaneous reverse voltage the diode can block repeatedly without breakdown under normal operating conditions. It is verified per JEDEC test methods and ensures safe operation when rectifying 120 VAC mains (peak ~170 V) only when used with appropriate safety margins and circuit protection - the 1N4002G R0G itself must not be subjected to voltages exceeding 100 V in reverse bias.

Does the 1N4002G R0G have AEC-Q101 qualification?

The base 1N4002G R0G is not AEC-Q101 qualified; however, Taiwan Semiconductor offers the AEC-Q101 variant as 1N4002GH (with 'H' suffix). The 1N4002G R0G shares identical electrical and mechanical specifications with the GH version except for the qualification testing - so design-in of 1N4002G R0G is permissible for non-automotive applications, while 1N4002GH must be specified for automotive use cases requiring AEC-Q101 compliance.

What is the forward voltage drop of the 1N4002G R0G at rated current?

The 1N4002G R0G has a maximum forward voltage (VF) of 1.0 V at 1 A forward current and 25°C junction temperature. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. In continuous operation, VF may rise slightly due to thermal effects - actual system-level conduction loss should be calculated using the 1N4002G R0G's thermal resistance (RθJA = 80°C/W) and ambient conditions.

What package type does the 1N4002G R0G use, and how is polarity identified?

The 1N4002G R0G uses the DO-204AL (DO-41) axial-leaded package with molded epoxy body and pure tin-plated leads. Polarity is clearly marked by a white or silver cathode band located near one lead end - the banded end is the cathode, and the opposite end is the anode. This marking is visible under standard visual inspection and compatible with automated optical recognition systems used in SMT reflow or selective soldering processes.

Is the 1N4002G R0G halogen-free and RoHS compliant?

Yes, the 1N4002G R0G is both RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated or chlorinated flame retardants, and all homogeneous materials meet EU Directive 2011/65/EU limits for lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE. This makes the 1N4002G R0G suitable for environmentally regulated markets including the EU, Japan, and China.
