Diodes Incorporated GBJ20005-F

Overview

GBJ20005-F from Diodes Incorporated is a 20A glass passivated single-phase bridge rectifier with 50V peak repetitive reverse voltage (VRRM), 1.05V forward voltage per element at 10A, and 240A non-repetitive surge current rating - designed for AC-to-DC conversion in industrial power supplies and motor control PCBs.

For engineers reviewing the GBJ20005-F datasheet, GBJ20005-F pinout, GBJ20005-F application, or GBJ20005-F equivalent, key selection criteria include its 20A average forward current at TC = 110°C, UL 94V-0 molded plastic case, through-hole #6 screw mounting, and RoHS-compliant tin-plated leads.

Technical Context

This bridge rectifier integrates four silicon diodes in a single GBJ package with glass-passivated junctions to ensure stable reverse leakage (<10 µA at 25°C) and high thermal reliability. Its 0.8°C/W junction-to-case thermal resistance enables operation up to +150°C junction temperature when mounted on a 300 × 300 × 1.6 mm copper heat sink.

The device supports single-phase, 60 Hz resistive or inductive loads without external snubbers; capacitive loads require 20% current derating. It delivers 240 A²s I²t fusing rating for transient surge protection and exhibits 60 pF typical capacitance per element at 1 MHz and 4 V reverse bias.

FAQ

What is the maximum case temperature for continuous operation of GBJ20005-F?

The GBJ20005-F supports continuous operation at TC = 110°C, delivering its full 20A average forward current rating. Exceeding this temperature requires linear derating per Figure 1 in the datasheet - e.g., ~15A at 125°C with heatsink, ~10A without heatsink. Thermal design must account for RJC = 0.8°C/W and PCB copper area.

Can GBJ20005-F be used in capacitive-input filter applications?

Yes, but with mandatory 20% current derating per the datasheet note. Capacitive-input filters cause higher peak currents and increased RMS heating; the device's 240A IFSM and 240 A²s I²t rating help withstand surge stress, but sustained operation above 16A average requires careful thermal validation and possibly forced-air cooling.

Is GBJ20005-F compatible with lead-free soldering processes?

Yes - it features lead-free (RoHS-compliant) tin-plated leads qualified per MIL-STD-202, Method 208. The device withstands standard lead-free reflow profiles (peak ~260°C) and wave soldering. Glass passivation and UL 94V-0 molding compound ensure stability during high-temperature assembly.

How does GBJ20005-F differ from GBJ2001-F?

GBJ20005-F has a 50V VRRM rating, while GBJ2001-F is rated for 100V. All other parameters - IO (20A), IFSM (240A), package (GBJ), and thermal specs - are identical. The choice depends strictly on required reverse voltage margin; GBJ20005-F suits low-voltage AC inputs (e.g., 24VAC control circuits), whereas GBJ2001-F targets 120VAC mains.
