Product details

Overview

GBJ608-F from Diodes Incorporated is a 6A standard recovery bridge rectifier with 800V maximum repetitive peak reverse voltage (V_RRM), 1.0V max forward voltage at 3A, and 5µA max reverse leakage current at 25°C. It features glass-passivated die construction, 1500V_RMS case dielectric strength, and is rated for 170A peak surge current - used in AC/DC front-end power supplies for industrial motor drives and HVAC control modules.

For engineers reviewing the GBJ608-F datasheet, GBJ608-F pinout, GBJ608-F application, or GBJ608-F equivalent, key selection criteria include V_RRM margin for line-voltage transients, thermal resistance (1.8°C/W junction-to-case), I_FSM capability for inrush handling, and UL recognition (E95060) for safety-compliant designs.

Technical Context

This single-package, four-terminal bridge rectifier integrates four silicon diodes in a full-wave configuration with molded plastic GBJ package. Its standard recovery characteristic (t_rr not specified but implied by "standard recovery" classification) supports line-frequency (50/60 Hz) rectification without significant switching loss concerns.

The device operates across –55°C to +150°C junction temperature range and delivers 6.0A average rectified output current when mounted on a 75 × 75 × 1.6 mm aluminum heatsink. Thermal resistance of 1.8°C/W enables predictable junction temperature rise under continuous conduction mode loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - Withstands 800V repetitive reverse voltage, suitable for 400VAC RMS input with 1.414× safety margin.
I_F(AV)	6.0 A - Sustains 6A average forward current with heatsink; derates to ~3.5A at 100°C ambient without forced cooling.
V_F Max	1.0 V @ 3A - Low conduction loss per diode leg; total bridge drop ~2.0V at full load, minimizing power dissipation.
I_FSM	170 A peak (8.3ms) - Handles high inrush currents during cold-start of transformer-coupled supplies or capacitive-input filters.
I_R Max	5 µA @ 25°C - Ensures minimal reverse conduction loss in high-impedance hold-up circuits or precision DC-link monitoring paths.
R_θJC	1.8 °C/W - Enables thermal design with measurable junction temperature rise; e.g., +108°C rise at 60W dissipation (6A × 1.0V × 2 diodes).
C_T	55 pF @ 1 MHz, 4V - Low junction capacitance minimizes EMI generation and high-frequency coupling in low-noise analog supply rails.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay GBU8K	Same 800V V_RRM, 8A I_F(AV), but larger GBU package (34.5 × 20.5 × 17.5 mm); VF = 1.1V @ 4A.	Higher current rating suits higher-power designs; requires larger PCB footprint and different mounting hardware.	Select when >6A continuous load or enhanced surge margin is required; verify heatsink compatibility with GBU outline.
ON Semiconductor GBPC608	Same 800V/6A rating, identical GBJ package, but VF = 1.05V @ 3A and IR = 10µA @ 25°C.	Slightly higher leakage may affect ultra-low-power standby performance; otherwise functionally interchangeable.	Acceptable drop-in replacement where 5µA vs. 10µA IR is not critical; confirm RoHS and date-code traceability alignment.

Compared with GBU8K, GBJ608-F offers tighter footprint and lower VF, while GBPC608 trades minor leakage increase for equivalent mechanical fit - both alternatives require validation of thermal performance under identical mounting conditions.

FAQ

What is the maximum operating junction temperature for GBJ608-F?

The GBJ608-F has a specified operating junction temperature range of –55°C to +150°C. This allows reliable operation in high-ambient environments such as enclosed motor drive cabinets or rooftop HVAC units. Derating curves in the datasheet define safe current limits above +100°C ambient, based on heatsink performance and airflow.

Is GBJ608-F suitable for use in automotive applications?

GBJ608-F is not AEC-Q101 qualified and is not intended for automotive safety-critical systems. While it meets industrial temperature and reliability requirements, Diodes recommends contacting their automotive team for PPAP-capable, IATF 16949-manufactured alternatives like the AEC-Q101-qualified GBJ608Q if automotive qualification is mandatory.

How does the GBJ package differ from KBPC or GBU packages?

The GBJ package is a compact, square-body, through-hole bridge rectifier with integrated mounting hole for #6 screw, measuring 30.0 × 20.0 × 17.5 mm. Unlike KBPC (larger, no mounting hole) or GBU (longer body, different terminal pitch), GBJ enables secure mechanical attachment and consistent thermal contact to heatsinks in space-constrained industrial layouts.

Can GBJ608-F be used without a heatsink?

GBJ608-F can operate without an external heatsink only at significantly reduced current - typically ≤1.5A average at +40°C ambient - due to its 1.8°C/W R_θJC and lack of low-R_θJA optimization. For 6A operation, the datasheet mandates mounting on a 75 × 75 × 1.6 mm aluminum plate; omitting this risks thermal runaway and premature failure.
