Diodes Incorporated GBJ802-F

Overview

GBJ802-F from Diodes Incorporated is a standard recovery 8A bridge rectifier with 200V maximum repetitive peak reverse voltage (VRRM), 1.0V forward voltage at 4A, and 5µA max reverse leakage at 25°C. It features glass-passivated die construction, 1500VRMS case dielectric strength, and is rated for 170A non-repetitive surge current - used in AC/DC power supplies for industrial control panels.

For engineers reviewing the GBJ802-F datasheet, GBJ802-F pinout, GBJ802-F application, or GBJ802-F equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (1.6°C/W junction-to-case), mounting torque limit (5.0 in-lbs), and RoHS-compliant lead-free plating for PCB assembly compliance.

Technical Context

This single-phase full-wave bridge rectifier integrates four silicon diodes in a molded GBJ package with through-hole mounting. Its standard recovery characteristic (typical trr > 500ns) suits line-frequency (50/60Hz) rectification where switching loss is not critical.

Designed for operation from –55°C to +150°C junction temperature, it delivers 8.0A average forward current at TC = +110°C with thermal management via aluminum plate heatsink (100mm × 100mm × 1.6mm). The 55pF typical junction capacitance per element minimizes high-frequency noise coupling in low-speed power conversion.

Key Specifications

Pinout & Package

Equivalent & Alternatives

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

Compared with GBJ802-F, GBU8K-E3 offers higher voltage headroom at the cost of size and slightly higher VF, while KBU8B reduces footprint and VF but sacrifices VRRM and surge capability - making GBJ802-F the balanced choice for 120VAC industrial systems requiring reliability and certification.

FAQ

What is the maximum mounting torque for GBJ802-F?

The maximum recommended mounting torque for GBJ802-F is 5.0 in-lbs when securing with a #6 screw. Exceeding this value risks cracking the molded plastic package or damaging internal wire bonds, potentially causing premature failure or reduced dielectric strength. Mounting must be performed on a flat, rigid surface with appropriate standoff height to avoid mechanical stress on leads during PCB flexure.

Is GBJ802-F qualified for automotive applications?

GBJ802-F is not AEC-Q101 qualified and is not intended for automotive use. While it operates from –55°C to +150°C, Diodes explicitly states that automotive-grade parts require separate qualification (AEC-Q101), PPAP capability, and IATF 16949 manufacturing - none of which apply to the standard GBJ802-F. For automotive designs, contact Diodes for AEC-Q101-certified alternatives such as the ABS20Q or GBJ1006Q series.

How does the 1.6°C/W thermal resistance translate to practical heatsinking?

With RθJC = 1.6°C/W, a 4W power dissipation (at 4A × 1.0V) results in a 6.4°C junction-to-case temperature rise. To maintain TJ ≤ +110°C at TA = +50°C, the case-to-ambient thermal path (including heatsink and interface material) must limit rise to ≤53.6°C, requiring a heatsink with RθCA ≤ 13.4°C/W. This assumes direct mounting to a 100mm × 100mm × 1.6mm aluminum plate as specified in the datasheet.

Can GBJ802-F replace GBJ801-F in a 100V design?

Yes - GBJ802-F (200V VRRM) is a direct upgrade over GBJ801-F (100V VRRM) in 100V-rated designs, offering doubled reverse voltage margin for improved reliability against line transients and aging effects. No circuit modification is needed, and both share identical package, pinout, IF, VF, and thermal characteristics. The higher VRRM adds no penalty in cost, size, or performance for 120VAC applications.
