Product details
Overview
KBJ602G from Diodes Incorporated is a 6.0A standard recovery bridge rectifier with 200V peak repetitive reverse voltage (VRRM), 1.0V forward voltage at 3.0A, and 5.0µA reverse leakage current at 25°C, designed for AC-to-DC conversion in offline power supplies and industrial control power stages.
For engineers reviewing the KBJ602G datasheet, KBJ602G pinout, KBJ602G application, or KBJ602G equivalent, key selection criteria include its 170A non-repetitive surge rating, 1.5°C/W junction-to-case thermal resistance, UL recognition (E95060), and through-hole KBJ package compatibility with PCB mounting using #6 screw.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a common molded plastic case, configured to deliver unidirectional DC output from AC input without external wiring. Its glass-passivated die construction ensures stable reverse characteristics across temperature, while the 2500VRMS case dielectric strength supports reinforced insulation in mains-connected equipment.
The device operates over –55°C to +150°C junction temperature range and requires derating to 4.8A average output current under capacitive load conditions. Thermal performance is specified with the unit mounted on a 75mm × 75mm × 1.6mm aluminum heatsink, enabling reliable conduction in compact industrial power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum peak reverse voltage the bridge withstands repeatedly; defines safe operating margin above 120VAC line peaks (≈170V). |
| IO @ TC=110°C | 6.0 A - Continuous average rectified output current when case temperature is held at 110°C; basis for heatsink sizing. |
| VF @ IF=3.0A | 1.0 V - Forward voltage drop per diode element; determines conduction loss (≈3W total at 3A full-wave output). |
| IR @ 25°C | 5.0 µA - Reverse leakage per element at rated DC blocking voltage; critical for low-power standby efficiency. |
| IFSM (8.3ms) | 170 A - Non-repetitive surge current capability; supports inrush handling during cold-start of transformer-based supplies. |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance per element; enables direct heatsink attachment for thermal management. |
| CT @ 1MHz | 80 pF - Typical capacitance per diode element; influences high-frequency noise coupling and EMI filter design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K (ON Semiconductor) | Same 6A/200V rating; 1.1V VF at 3A; 10µA IR at 25°C; GBU package (larger footprint, higher RθJC = 2.0°C/W). | Requires larger PCB area and more thermal margin; suitable where legacy GBU footprint exists. | Select if existing GBU layout is fixed and thermal headroom exceeds 1.5W dissipation. |
| W04 (Vishay) | 4A/400V rating; smaller KBL package; 1.1V VF at 1.5A; 5µA IR; lower surge (100A). | Lower current and higher VRRM; insufficient for 6A continuous loads at 200V. | Only acceptable for derated use ≤4A or where 400V isolation is prioritized over current capacity. |
Compared with GBU6K and W04, KBJ602G offers optimal balance of 6A current delivery, 200V rating, low 1.0V VF, and compact KBJ footprint-making it preferred for space-constrained 120VAC industrial power supplies requiring UL recognition and surge robustness.

FAQ
What is the maximum allowable case temperature for continuous operation of KBJ602G?
The KBJ602G is rated for continuous operation at a case temperature (TC) of up to +110°C, as specified in its maximum ratings table. Exceeding this temperature requires current derating per the thermal curve in DS21207 Rev. 10–2, and sustained operation above +110°C risks accelerated parametric drift and reduced lifetime.
Can KBJ602G be used in capacitive-input filter configurations without derating?
No-Diodes specifies a 20% current derating for capacitive load applications. At full 6.0A rating, the device must be operated at ≤4.8A average output current when feeding a bulk capacitor input, due to increased RMS current stress and peak diode conduction angles that elevate junction temperature beyond safe limits.
Is KBJ602G qualified to AEC-Q101 for automotive use?
No-KBJ602G is not AEC-Q101 qualified. The datasheet explicitly states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing; standard KBJ602G is intended for industrial and commercial applications only unless separately qualified by Diodes upon request.
What is the recommended minimum creepage and clearance distance for KBJ602G on PCB?
While Diodes does not specify PCB layout distances, the 2500VRMS dielectric strength and UL E95060 recognition imply minimum creepage ≥3.2mm and clearance ≥2.5mm for 200V working voltage per IPC-2221B. Actual spacing must comply with end-equipment safety standards (e.g., IEC 62368-1) and be validated with hi-pot testing at 2500VAC for 60 seconds.
