Diodes Incorporated GBJ2001-F

Overview

GBJ2001-F from Diodes Incorporated is a 20A glass passivated single-phase bridge rectifier with 100V peak repetitive reverse voltage (VRRM), 70V RMS reverse voltage, and 1.05V forward voltage per element at 10A. It features 240A non-repetitive surge current capability and is designed for through-hole PCB mounting with #6 screw fastening in industrial power supplies and AC/DC adapters.

For engineers reviewing the GBJ2001-F datasheet, GBJ2001-F pinout, GBJ2001-F application, or GBJ2001-F equivalent, key selection factors include its 20A average forward current rating at TC = 110°C, 0.8°C/W junction-to-case thermal resistance, UL 94V-0 flammability rating, and RoHS-compliant lead-free plating - all critical for thermally constrained, safety-certified AC input stages.

Technical Context

This bridge rectifier integrates four silicon diodes in a single GBJ package with glass passivated junctions to suppress leakage and enhance reliability under high-temperature operation. Its 1500VRMS dielectric strength between case and terminals supports reinforced insulation in Class II power supplies.

The device operates across –55°C to +150°C junction temperature range and requires derating to 16A for capacitive loads. Thermal performance is specified with a 300 × 300 × 1.6 mm copper heat sink, enabling stable conduction in compact open-frame designs without forced airflow.

FAQ

What is the maximum allowable case temperature for continuous operation of GBJ2001-F?

The GBJ2001-F is rated for 20A average forward current at TC = 110°C. Operation beyond this temperature requires linear derating per Figure 1 in the datasheet: at TC = 125°C, IO drops to approximately 16.5A. Exceeding 150°C junction temperature risks permanent degradation of the glass-passivated junctions.

Can GBJ2001-F be used in capacitive-input filter configurations without derating?

No. The datasheet explicitly states that current must be derated by 20% for capacitive loads. In such configurations, the peak charging current stresses the diodes more severely than resistive or inductive loads, so the usable average current is limited to 16A to maintain reliability and avoid premature failure.

Is the GBJ2001-F suitable for surface-mount assembly?

No. The GBJ package is strictly through-hole with axial leads and a mounting hole for #6 screws. It lacks solder pads or gull-wing leads required for reflow or wave soldering. Attempting SMT assembly would compromise mechanical integrity, thermal path, and UL mounting compliance.

Does GBJ2001-F meet IPC/JEDEC J-STD-020 moisture sensitivity requirements?

Yes. The device is rated Moisture Sensitivity Level 1 per J-STD-020C, meaning it has unlimited floor life at ≤30°C/60% RH and does not require dry-packaging or baking prior to soldering - simplifying manufacturing logistics for high-volume PCB assembly.
