Diodes Incorporated GBJ25L06

Overview

GBJ25L06 from Diodes Incorporated is a 25A, 600V glass-passivated single-phase bridge rectifier with low forward voltage (0.92 V max at 12.5 A), 320 A peak surge capability, and UL 94V-0 plastic package. It serves as AC-to-DC conversion front-end in industrial power supplies, motor drives, and HVAC control boards requiring high thermal robustness and PCB-mount reliability.

For engineers reviewing the GBJ25L06 datasheet, GBJ25L06 pinout, GBJ25L06 application, or GBJ25L06 equivalent, key selection criteria include its 0.92 V VF max at 12.5 A, 600 V VRRM rating, 320 A IFSM surge tolerance, TJ = –40°C to +150°C operating range, and GBJ through-hole package compatibility with heatsink mounting.

Technical Context

This bridge rectifier integrates four silicon diodes in a single GBJ package with glass-passivated junctions for enhanced reliability under repetitive surge stress. Its 0.87 V typical forward voltage at 25°C and 0.92 V maximum at 12.5 A directly reduce conduction losses in high-current DC bus stages.

Thermal performance is defined by RθJC = 0.8°C/W (with heatsink) and RθJL = 5°C/W (lead-to-ambient), enabling stable operation up to 150°C junction temperature. Reverse recovery time is 3 µs, supporting line-frequency and moderate-switching applications without excessive switching loss.

Equivalent & Alternatives

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

Compared with GBJ25JL and GBU25J, the GBJ25L06 offers balanced thermal performance and cost for established industrial designs, though its 0.92 V VF and obsolescence notice make GBJ25JL the recommended upgrade path for new projects.

FAQ

Is GBJ25L06 RoHS 3 and halogen-free compliant?

Yes. The GBJ25L06 meets EU Directive 2015/863/EU (RoHS 3) and is halogen- and antimony-free per Diodes' "Green" definition: <900 ppm bromine, <900 ppm chlorine (<1500 ppm total Br + Cl), and <1000 ppm antimony compounds.

What is the maximum heatsink temperature for reliable operation at 25 A?

At 25 A average forward current, case temperature (TC) must not exceed +115°C per datasheet derating curve. With RθJC = 0.8°C/W, a 60°C heatsink requires ≤48°C temperature rise across the interface-achievable using thermal grease and ≥200 cm² aluminum heatsink surface area.

Can GBJ25L06 replace GBJ25JL in existing designs?

Yes, GBJ25L06 is pin- and footprint-compatible with GBJ25JL and shares identical VRRM, IF(AV), and package dimensions. However, GBJ25JL has lower VF (0.85 V max), so substitution may slightly increase conduction loss and thermal load in high-duty-cycle applications.

Why is GBJ25L06 marked "not recommended for new designs"?

Diodes has designated GBJ25L06 as not recommended for new designs because the improved GBJ25JL (lower VF, same package/rating) is now the preferred version. This reflects a product lifecycle transition-not obsolescence-and existing GBJ25L06 designs remain fully supported with no announced discontinuance date.
