SMC Diode Solutions GBJ2010

Overview

GBJ2010 from Diodes Incorporated is a 20A glass passivated single-phase bridge rectifier with 1000V peak repetitive reverse voltage (VRRM), 700V RMS reverse voltage, and 1.05V forward voltage per element at 10A. It features through-hole GBJ package mounting for #6 screw, 0.8°C/W thermal resistance junction-to-case, and UL 94V-0 molded plastic case - used in AC/DC power supplies for industrial motor drives.

For engineers reviewing the GBJ2010 datasheet, GBJ2010 pinout, GBJ2010 application, or GBJ2010 equivalent, key selection criteria include VRRM rating for line-voltage surge margin, IFSM=240A capability for inrush handling, thermal derating curves for heatsinkless operation, and RoHS-compliant lead-free plating compatibility with IPC-J-STD-020C reflow profiles.

Technical Context

The GBJ2010 integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions for enhanced reliability under high dv/dt and transient stress. Its 1000V blocking rating supports universal input (85–265VAC) rectification in offline SMPS front-ends.

Thermal performance is defined with 0.8°C/W R_θJC when mounted on a 300×300×1.6mm Cu heat sink; without heatsink, average forward current derates to ~10A at T_C=110°C per Fig. 1. Reverse leakage remains ≤500µA at 125°C and rated DC blocking voltage.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar bridge rectifier applications.

Compared with GBU10K and GBPC3510, the GBJ2010 uniquely balances mechanical ruggedness (screw-mount GBJ case), thermal efficiency (0.8°C/W), and standardized 15/unit tube packaging - making it optimal for medium-power industrial OEM production where serviceability and thermal predictability are prioritized over miniaturization or extreme surge headroom.

Availability

GBJ2010 is available at Aetrix Electronics and suitable for industrial motor drives, offline switch-mode power supplies, uninterruptible power systems, and medical diagnostic power modules requiring stable component supply across multi-year production cycles.

Supply support for GBJ2010 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

FAQ

What is the maximum allowable case temperature for continuous operation?

The GBJ2010 is rated for continuous operation at T_C = 110°C, delivering its full 20A average forward current. Above this temperature, current must be linearly derated per Fig. 1 in DS21220 - e.g., to ~15A at 125°C case temperature. Derating assumes no heatsink; with a 300×300×1.6mm Cu plate, junction temperature remains within -55°C to +150°C limits.

Can GBJ2010 be used with capacitive loads without derating?

No. The datasheet explicitly states: "For capacitive load, derate current by 20%." This is due to high inrush current peaks that exceed the 8.3ms IFSM rating during repeated charge cycles. For bulk-capacitor inputs, limit I_O to 16A or implement NTC thermistor or active inrush limiting to maintain reliability.

Is the GBJ2010 compatible with lead-free reflow soldering processes?

Yes. The device uses lead-free tin-plated leads qualified per MIL-STD-202, Method 208, and complies with J-STD-020C moisture sensitivity level 1. Peak reflow temperature must not exceed 260°C for ≤10 seconds; preheat and soak profiles must follow JEDEC J-STD-020 guidelines to avoid internal delamination or bond wire damage.

Does the GBJ2010 require forced-air cooling in typical applications?

No. At 20A IO and T_C=110°C, natural convection cooling suffices when mounted on a 300×300×1.6mm copper heat sink. Without heatsink, the device supports only ~10A IO at the same case temperature. Forced air is unnecessary unless ambient exceeds 70°C or enclosure airflow is restricted - verified via thermal imaging per Fig. 1 derating curve.
