Product details
Overview
GBJ20005 from Diodes Incorporated is a 20A glass passivated single-phase bridge rectifier with 50V peak repetitive reverse voltage, 1.05V forward voltage at 10A per element, 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 datasheet, GBJ20005 pinout, GBJ20005 application, or GBJ20005 equivalent, key selection factors include its 20A average forward current at 110°C case temperature, 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 to convert AC input into full-wave DC output. It features glass passivated junctions for enhanced reliability under thermal cycling and high humidity, with a rated I²t of 240 A²s for transient surge protection.
Thermal resistance is specified at 0.8°C/W junction-to-case when mounted on a 300 × 300 × 1.6 mm copper heat sink. Its typical capacitance per element is 60 pF at 1 MHz and 4 V reverse bias, supporting stable operation in 50/60 Hz line-frequency applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU20K (ON Semiconductor) | Same 20A/50V rating, but GBU package (smaller footprint, lower thermal mass) | Limited to lower-duty-cycle applications due to higher RJC (1.2°C/W) | Select when board space is constrained and heatsink area is limited |
| KBP205 (Shindengen) | 50V VRRM, 20A IO, but lead-free plating not explicitly certified to RoHS Annex exemptions | Not approved for life-critical or export-controlled equipment requiring full RoHS traceability | Choose only for cost-sensitive consumer-grade designs with relaxed compliance scope |
Compared with GBU20K and KBP205, the GBJ20005 offers superior thermal performance (0.8°C/W), UL recognition, and documented RoHS exemption coverage - making it preferred for industrial and regulated equipment where long-term reliability and certification alignment are mandatory.

FAQ
What is the maximum recommended case temperature for continuous operation?
The GBJ20005 is rated for 20A average forward current at TC = 110°C. Operation above this temperature requires derating per Figure 1 in the datasheet. At TC = 125°C, the usable current drops to approximately 16A for resistive loads without heatsink, and 18A with heatsink.
Can GBJ20005 be used in capacitive-input filter applications?
Yes, but with 20% current derating as specified in the datasheet. For example, at TC = 110°C, the usable IO reduces from 20A to 16A. This accounts for higher peak currents drawn by capacitor-input filters during AC zero-crossing recovery.
Is the GBJ20005 suitable for surface-mount assembly?
No - the GBJ package is strictly through-hole with screw-mount capability. It lacks SMD-compatible terminations or reflow profile specifications. Use GBJ20005 only in plated-through-hole PCBs with mechanical mounting provisions.
Does the device require external snubbing in inductive load circuits?
Snubbing is not required for standard 50/60Hz inductive loads within rated voltage and current. However, for fast-switching inductive loads (e.g., PWM-driven solenoids), a RC snubber across AC terminals is recommended to suppress voltage spikes exceeding 50V peak reverse rating.
