Product details

Overview

1N4002GHR0G 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 in a DO-204AL (DO-41) package, optimized for DC/DC converters and switching-mode power supplies with low forward voltage drop and high surge capability.

For engineers reviewing the 1N4002GHR0G datasheet, 1N4002GHR0G pinout, 1N4002GHR0G application, or 1N4002GHR0G equivalent, key selection criteria include verified V_RRM = 100 V, I_F = 1 A, I_FSM = 30 A (8.3 ms), V_F ≤ 1.0 V @ 1 A, and T_J max = 150 °C - all confirmed for this exact marking variant.

Technical Context

This device operates as a single-die, unidirectional PN junction rectifier with glass-passivated chip construction ensuring stable reverse leakage and robust thermal performance. Its 80 °C/W junction-to-ambient thermal resistance and 0.33 g mass support reliable conduction in compact through-hole power stages.

The 1N4002GHR0G exhibits defined electrical behavior across temperature: reverse current ≤ 5 µA at 25 °C and ≤ 100 µA at 125 °C under rated V_R, and junction capacitance of 10 pF at 1 MHz / 4 V reverse bias - parameters validated per Taiwan Semiconductor P2104 specification.

FAQ

What is the peak repetitive reverse voltage rating for 1N4002GHR0G?

The 1N4002GHR0G has a peak repetitive reverse voltage (V_RRM) rating of 100 V, as specified in Taiwan Semiconductor's P2104 datasheet. This value defines the maximum reverse-biased voltage the diode can block repeatedly without avalanche breakdown. It is distinct from the 1N4001G (50 V) and 1N4003G (200 V) variants in the same family, confirming 1N4002GHR0G's precise voltage grade positioning.

Does 1N4002GHR0G meet AEC-Q101 qualification requirements?

No - the "H" suffix in the ordering code denotes AEC-Q101 qualification, but 1N4002GHR0G does not carry the "H". The "R0G" suffix indicates green compound and tape-and-reel packaging (5,000 pcs), while AEC-Q101 versions are marked as 1N4002GH or 1N4002GHA0G. Therefore, 1N4002GHR0G is intended for industrial and commercial applications, not automotive-grade use.

What is the forward voltage drop of 1N4002GHR0G at rated current?

The forward voltage (V_F) of 1N4002GHR0G is guaranteed ≤ 1.0 V at I_F = 1 A and T_J = 25 °C, per the electrical specifications table in the P2104 datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) and represents the conduction loss baseline for thermal and efficiency calculations in linear or low-frequency switching power stages using the 1N4002GHR0G.

What package type is used for 1N4002GHR0G?

The 1N4002GHR0G uses the DO-204AL (commonly known as DO-41) axial-leaded package, with pure tin-plated leads compliant with J-STD-002 solderability requirements. Its mechanical outline conforms to JEDEC standards, features UL 94V-0 flammability-rated epoxy, and weighs approximately 0.330 g - all confirmed in the Mechanical Data section of the Taiwan Semiconductor P2104 document for the 1N4002GHR0G variant.

How does the junction capacitance of 1N4002GHR0G affect circuit performance?

The 1N4002GHR0G exhibits a typical junction capacitance (C_J) of 10 pF at 1 MHz and 4.0 V reverse bias. This value influences high-frequency noise coupling and reverse recovery behavior in switching applications. While negligible in 50/60 Hz rectification, it becomes relevant in >10 kHz SMPS designs - making the 1N4002GHR0G best suited for low-frequency power conversion where its low V_F and high surge rating outweigh capacitive limitations.
