Diodes Incorporated GBJS4010

Overview

GBJS4010 from Diodes Incorporated is a 40A standard recovery bridge rectifier in GBJS package, rated for 1000V repetitive peak reverse voltage, 1.1V max forward voltage at 20A, and 5µA max reverse leakage at 25°C. It features glass-passivated die construction, ceramic heat sink on backside for superior thermal conductivity, and UL recognition (E95060), used in industrial AC-DC power supplies and motor drive front-end rectification.

For engineers reviewing the GBJS4010 datasheet, GBJS4010 pinout, GBJS4010 application, or GBJS4010 equivalent, key selection criteria include its 360A non-repetitive surge rating (8.3ms), 0.45°C/W junction-to-case thermal resistance, RoHS-compliant matte tin plating, and suitability for heatsink-mounted high-current rectification where thermal management and reliability under transient overloads are critical.

Technical Context

This bridge rectifier integrates four standard recovery diodes in a single-phase full-wave configuration with common cathode/anode topology. Its glass-passivated junction ensures stable reverse characteristics across -55°C to +150°C operating range and supports high I²t fusing capability (537 A²s) for line-voltage surge immunity.

The GBJS package uses a copper baseplate with ceramic thermal interface and matte tin-plated leads solderable per MIL-STD-202 Method 208. Dielectric strength is rated at 2500V_RMS, and thermal resistance junction-to-ambient is 1.7°C/W when mounted on a 250×250×10mm Cu plate.

FAQ

What is the maximum allowable case temperature for continuous 40A operation?

The GBJS4010 sustains 40A average forward current only when case temperature (T_C) is maintained at ≤+120°C using an appropriate heatsink. Without heatsink, derating begins immediately above 25°C ambient, limiting usable current to 4.0A at T_C = +120°C. Thermal design must account for R_θJC = 0.45°C/W and mounting torque (0.5 N·m recommended).

Is GBJS4010 qualified for automotive applications?

No-GBJS4010 is not AEC-Q101 qualified. While Diodes offers AEC-Q101-certified bridge rectifiers (e.g., GBJ1010Q), this part lacks PPAP documentation, automotive change control, and IATF 16949-specific process validation. It is intended for industrial, commercial, and general-purpose power applications only.

Can GBJS4010 be mounted directly to a PCB without a heatsink?

Yes, but only for very low-duty-cycle or intermittent operation. At 25°C ambient, the derating curve shows ≤4.0A average current without heatsink. Continuous use above this requires forced-air cooling or metal-core PCB; sustained 40A operation mandates a heatsink with thermal interface and proper mounting torque (0.5 N·m).

What does the "Green" marking on GBJS4010 signify?

The "Green" marking indicates compliance with Diodes' halogen- and antimony-free definition: <900ppm bromine, <900ppm chlorine (<1500ppm total Br+Cl), and <1000ppm antimony compounds. It confirms full RoHS 3 (2015/863/EU) compliance and aligns with IPC-1752A material declaration requirements for environmental reporting.
