Product details
Overview
KBJ610G from Diodes Incorporated is a 6.0A, 1000V peak repetitive reverse voltage standard recovery bridge rectifier in KBJ package, with 1.0V max forward voltage at 3A per element, 5.0µA max reverse leakage at 25°C, and 170A non-repetitive surge rating - used in AC/DC front-end power conversion for industrial power supplies and motor drive input stages.
For engineers reviewing the KBJ610G datasheet, KBJ610G pinout, KBJ610G application, or KBJ610G equivalent, key selection criteria include VRRM=1000V, IO=6.0A at TC=110°C, thermal resistance RθJC=1.5°C/W, surge capability IFSM=170A, and UL recognition under file E95060 for safety-critical board-level designs.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon junction diodes in a molded plastic KBJ package with glass-passivated die construction. It delivers 6.0A average rectified output current at case temperature TC=110°C and supports 60Hz resistive/inductive loads without derating (20% derating required for capacitive loads).
Its 2500VRMS case dielectric strength, 80pF typical junction capacitance per element at 1MHz/4V, and 120A²s I²t fusing rating define its robustness in transient-prone mains-input environments - especially where high-voltage isolation and surge immunity are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands 1000V peak reverse voltage across AC input terminals without breakdown. |
| IO | 6.0 A @ TC=110°C - Sustains continuous 6A DC output current when mounted on heatsink with case temp held at 110°C. |
| VF Max | 1.0 V @ IF=3A - Forward drop per diode element limits conduction loss to ≤3W total at 6A full-wave output. |
| IR Max | 5.0 µA @ 25°C - Ultra-low reverse leakage preserves efficiency in high-impedance hold-up or sensing circuits. |
| IFSM | 170 A - Survives 8.3ms half-sine surge events common during cold-start or line transients. |
| RθJC | 1.5 °C/W - Enables thermal design with minimal heatsink mass when mounted on 75×75×1.6mm Al plate. |
| CT | 80 pF - Low junction capacitance minimizes EMI generation and switching noise coupling in SMPS inputs. |
Pinout & Package
Package: KBJ - Molded plastic through-hole package with bright tin-plated leads, UL 94V-0 flammability rating, 4.3g weight, and #6 screw mounting provision (max torque 5.0 in-lbs). Polarity marked on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Input AC Terminal 1 | One of two AC input pins; connects to live/phase side of transformer secondary or line filter. |
| AC2 | Input AC Terminal 2 | Second AC input pin; completes full-wave bridge input path with AC1. |
| + (Anode) | Positive DC Output | Full-wave rectified positive output node; ties to bulk capacitor anode or downstream regulator input. |
| – (Cathode) | Negative DC Output | Full-wave rectified negative output node; serves as system ground reference or return path. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances long-term reliability and moisture resistance in humid or contaminated environments. |
| 2500VRMS dielectric strength | Meets reinforced insulation requirements for Class II AC/DC converters without additional barriers. |
| UL Recognized (E95060) | Validates compliance with UL 60950-1/62368-1 for end-equipment safety certification. |
| 170A surge rating | Eliminates need for external NTC or MOV in many 115/230VAC input designs with moderate inrush. |
| Lead-free & RoHS 3 compliant | Supports global environmental compliance without solderability or reliability trade-offs. |
Applications
| Industrial Power Supply Input Stage | Motor Drive Front-End Rectification |
|---|---|
Use Scenario: Converts 230VAC mains to unregulated DC bus in DIN-rail mounted 200W industrial PSUs. IC Role / Device Role / Timing Role: Full-wave bridge rectifier providing isolated, high-voltage DC input to PFC stage. Use Value: 1000V VRRM ensures margin against 230VAC +10% + line spikes; 6A IO supports >150W continuous output. | Use Scenario: Rectifies transformer-isolated 115VAC supply feeding H-bridge gate drivers in servo amplifiers. IC Role / Device Role / Timing Role: Primary AC-to-DC conversion block before bulk storage and DC link filtering. Use Value: 170A IFSM handles repeated motor stall surges; low IR prevents thermal runaway during extended idle periods. |

Use Scenario: Provides DC bus for constant-current LED driver ICs in outdoor streetlight fixtures. IC Role / Device Role / Timing Role: Mains-side rectification stage preceding buck or flyback controller. Use Value: UL recognition simplifies end-product safety approval; 80pF CT reduces conducted EMI into EMC filters. | Use Scenario: Powers microcontroller and relay logic in white-goods control boards (e.g., washing machine main PCB). IC Role / Device Role / Timing Role: Input rectifier converting 12VAC control transformer output to low-voltage DC rail. Use Value: 6.0A IO headroom accommodates solenoid actuation peaks; KBJ package enables compact through-hole layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU10K | Same 1000V VRRM, 10A IO rating, but GBU package (larger footprint, higher RθJC=2.0°C/W). | Higher current capacity suits 300W+ designs; requires more PCB area and larger heatsink. | Select when >6A continuous load or lower thermal margin exists; verify mounting hole compatibility. |
| KBPC610 | Same 1000V/6A rating, but KBPC package (square base, 4-pin layout) and 2000VRMS isolation. | Higher dielectric strength supports medical-grade isolation; different pin pitch (2.54mm vs KBJ's 5.08mm). | Choose for enhanced safety isolation or legacy KBPC footprint reuse; check PCB pad layout. |
Compared with GBU10K and KBPC610, KBJ610G offers optimal balance of compact KBJ footprint, 1.5°C/W thermal resistance, UL recognition, and cost-efficiency for 100–200W industrial and appliance power stages.

FAQ
What is the maximum operating temperature for KBJ610G?
KBJ610G has an operating junction temperature range of –55°C to +150°C and is rated for 6.0A average output current at case temperature TC = +110°C. Thermal design must ensure case temperature does not exceed this limit under worst-case ambient and airflow conditions, using the specified 1.5°C/W RθJC value with proper heatsinking.
Is KBJ610G suitable for use in automotive applications?
KBJ610G is not AEC-Q200 qualified and is not recommended for automotive under-hood applications. While it meets general industrial reliability standards and operates over –55°C to +150°C, Diodes specifies that automotive-grade parts require explicit AEC-Q200 qualification, PPAP capability, and IATF 16949 manufacturing - which this device does not carry.
How does the KBJ package differ from KBPC or GBU packages?
The KBJ package is a compact, rectangular, 4-terminal through-hole bridge with 5.08mm pin pitch and #6 screw mounting provision. KBPC uses a square base with 2.54mm pin pitch and no mounting hole; GBU is larger with higher thermal resistance (2.0°C/W) and 5.08mm pitch but no screw mount. KBJ balances size, thermal performance, and mechanical stability.
Does KBJ610G require derating for capacitive loads?
Yes - the datasheet explicitly states that for capacitive loads, the average rectified output current IO must be derated by 20%. This accounts for higher peak currents and increased thermal stress during capacitor charging; therefore, maximum usable current drops to 4.8A when feeding bulk electrolytic capacitors directly after rectification.
