Diodes Incorporated 1N4002GL-T

Overview

1N4002GL-T from Diodes Incorporated is a glass-passivated silicon rectifier diode rated for 1.0A average forward current and 100V peak repetitive reverse voltage, with 30A non-repetitive surge capability and 1.0V forward voltage at 1.0A. It serves as a general-purpose AC-to-DC power supply rectifier in low-frequency (60Hz) linear power supplies for consumer electronics, industrial controls, and embedded power rails.

For engineers reviewing the 1N4002GL-T datasheet, 1N4002GL-T pinout, 1N4002GL-T application, or 1N4002GL-T equivalent, key selection criteria include its DO-41 package compatibility, 100V blocking rating versus input voltage margins, thermal resistance (100°C/W), reverse recovery time (2.0 µs), and RoHS-compliant tin-plated leads for lead-free assembly.

Technical Context

This device operates as a single-phase, half-wave rectifier under resistive or inductive loads at 60Hz. Its glass-passivated die construction ensures stable junction performance and enhanced moisture resistance compared to epoxy-passivated variants.

It exhibits a typical reverse recovery time of 2.0 µs (measured at IF = 0.5A, IR = –1A, Irr = 0.25A) and total capacitance of 8.0 pF at 1.0 MHz and 4.0V reverse bias - characteristics critical for minimizing switching noise and EMI in low-speed rectification circuits.

FAQ

Is 1N4002GL-T suitable for use in a 230VAC input circuit?

No. With a 100V peak repetitive reverse voltage rating, 1N4002GL-T is limited to 120VAC nominal systems (170V peak). For 230VAC (325V peak), use 1N4004G-T (400V) or higher. Exceeding VRRM risks catastrophic junction breakdown and permanent failure.

What is the meaning of "GL" in the part number 1N4002GL-T?

The "GL" suffix denotes glass-passivated die construction, distinguishing it from older epoxy-passivated versions. This improves humidity resistance, leakage stability, and long-term reliability in harsh environments - confirmed in Diodes' DS29002 datasheet Rev. 8-2.

Can 1N4002GL-T replace 1N4002 in existing designs?

Yes - it is a direct functional and mechanical replacement: identical DO-41 package, 100V PIV, 1.0A IO, 1.0V VF, and 30A surge rating. The "GL" variant adds glass passivation and RoHS compliance, with no layout or thermal changes required.

Does this diode require a heatsink in standard operation?

No heatsink is required at ≤1.0A average current and ≤75°C ambient, provided leads are trimmed to 9.5mm from the case per datasheet condition. At higher ambient temperatures or sustained >750mA, PCB copper area or airflow should be evaluated using its 100°C/W RθJA value.
