SMC Diode Solutions GBJ2002

Overview

GBJ2002 from Diodes Incorporated is a 20A glass passivated single-phase bridge rectifier with 200V peak repetitive reverse voltage (VRRM), 140V RMS reverse voltage, and 1.05V forward voltage per element at 10A. It features low thermal resistance (0.8°C/W), 240A non-repetitive surge rating, and UL 94V-0 molded plastic case for PCB mounting via #6 screw.

For engineers reviewing the GBJ2002 datasheet, GBJ2002 pinout, GBJ2002 application, or GBJ2002 equivalent, key selection criteria include its 20A average forward current at TC = 110°C, 240A IFSM surge capability, 60pF typical junction capacitance, and through-hole GBJ package suitability for industrial power supplies and AC/DC front-end rectification.

Technical Context

The GBJ2002 integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions for enhanced reliability under thermal and voltage stress. Its design supports resistive or inductive loads at 60Hz without heatsink up to 10A, and up to 20A with heatsink - per Fig. 1 derating curve.

Thermal performance is defined with junction-to-case resistance of 0.8°C/W when mounted on a 300 × 300 × 1.6 mm Cu plate. Reverse leakage remains ≤10 µA at 25°C and ≤500 µA at 125°C under rated DC blocking voltage, enabling stable operation in high-temperature industrial environments.

FAQ

What is the maximum operating temperature for GBJ2002?

The GBJ2002 has a specified junction and storage temperature range of –55°C to +150°C. Its 20A average forward current rating is defined at case temperature (TC) = 110°C, and derating curves show usable current drops to ~15A at TC = 125°C and ~10A at TC = 135°C without heatsink - confirming safe operation up to 150°C junction temperature under controlled thermal conditions.

Can GBJ2002 be used in capacitive-load applications?

Yes, but with mandatory current derating: the datasheet specifies a 20% reduction in average forward current (IO) when driving capacitive loads. For example, the 20A rating at TC = 110°C becomes 16A under capacitive loading, due to higher peak currents and increased thermal stress during capacitor charging cycles.

Is GBJ2002 lead-free and RoHS compliant?

Yes, GBJ2002 features lead-free (tin-finish) plating and is RoHS compliant per EU Directive 2002/95/EC revision 13.2.2003. It also meets JEDEC Level 1 moisture sensitivity and carries UL Recognized Component status (File E94661), with exemptions applied for glass and high-temperature solder per Annex Notes 5 and 7.

How is the GBJ2002 mounted mechanically?

GBJ2002 uses a through-hole GBJ package designed for #6 screw mounting. The case includes threaded holes and mounting flanges; maximum recommended torque is 5.0 in-lbs. It is not intended for standard PCB pad soldering alone - mechanical fastening is required to ensure thermal contact with heatsinks and structural integrity under vibration or thermal cycling.
