Product details
Overview
KBP06G from Diodes Incorporated is a 1.5A standard recovery bridge rectifier with 600V maximum repetitive peak reverse voltage (VRRM), 1.1V forward voltage drop at 1.5A, and 5µA reverse leakage current at 25°C. It features glass-passivated die construction, 1500VRMS case dielectric strength, and 40A non-repetitive surge rating - used in AC/DC power supplies for industrial control panels and LED drivers.
For engineers reviewing the KBP06G datasheet, KBP06G pinout, KBP06G application, or KBP06G equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (18°C/W junction-to-case), PCB-mount compatibility, and UL recognition (E95060) for safety-critical power conversion designs.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a KBP package with common-cathode and common-anode configuration. Its standard recovery time (~2µs) supports 50/60Hz line-frequency operation without significant switching loss, and it is rated for 1.5A average output current at TC = +105°C.
The device uses matte tin-plated terminals compliant with MIL-STD-202 Method 208, operates across –55°C to +150°C junction temperature range, and delivers 20pF typical junction capacitance - enabling stable performance in capacitive-input and inductive-load rectification circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak reverse voltage up to 600V, suitable for 400VAC input systems with safety margin. |
| IO | 1.5 A - Continuous average rectified output current at TC = +105°C, defining heatsink sizing requirement. |
| VF max | 1.1 V @ 1.5A - Forward voltage drop determines conduction loss (1.65W max at full load) and thermal design. |
| IR max | 5 µA @ 25°C - Low reverse leakage ensures minimal standby power loss in off-state applications. |
| IFSM | 40 A - Peak surge current rating for 8.3ms half-sine wave, supporting cold-start inrush tolerance. |
| RθJC | 18 °C/W - Junction-to-case thermal resistance measured on 75mm × 75mm × 1.6mm Cu heatsink. |
| TJ range | –55°C to +150°C - Wide operating temperature enables use in automotive under-hood and industrial ambient environments. |

Applications
| Industrial AC/DC Power Supplies | LED Driver Input Stage |
|---|---|
Use Scenario: Converts 230VAC mains to unregulated DC in DIN-rail mounted power supplies for PLC I/O modules. IC Role / Device Role / Timing Role: Full-wave bridge rectifier providing isolated, low-loss AC-to-DC conversion before bulk capacitor filtering. Use Value: 600V VRRM provides 2× safety margin over 230VAC peak (325V), minimizing risk of reverse breakdown during line spikes. | Use Scenario: Rectifies 120VAC input in constant-current LED drivers for street lighting fixtures. IC Role / Device Role / Timing Role: Primary rectification stage delivering ripple-suppressed DC to downstream buck converter. Use Value: 1.1V VF limits conduction loss to ≤1.65W at 1.5A, reducing thermal stress on compact aluminum housing. |

Use Value: –55°C to +150°C operating range ensures functionality in engine bay or under-dash mounting locations. |
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 KBP package, 600V VRRM, but 1.05V VF max and 10µA IR max at 25°C. | Slightly lower conduction loss but higher leakage; less suited for low-power standby modes. | Select when optimizing for efficiency over leakage-sensitive standby performance. |
| W06M (Vishay) | Same 600V/1.5A rating, but WOB package (wider lead spacing); RθJC = 20°C/W vs. KBP06G's 18°C/W. | Requires larger PCB footprint; thermal performance marginally reduced for same heatsink area. | Choose only if legacy WOB footprint compatibility is required in redesigns. |
Compared with GBU6K and W06M, KBP06G offers the lowest thermal resistance (18°C/W) and tightest leakage spec (5µA), making it optimal for thermally constrained or low-standby-power industrial designs where UL recognition and RoHS 3 compliance are mandatory.

FAQ
What is the maximum allowable case temperature for continuous operation?
The KBP06G is rated for 1.5A average output current at TC = +105°C. Exceeding this temperature requires derating per the datasheet's thermal curves. The absolute maximum junction temperature is +150°C, and thermal design must ensure RθJC × PLOSS + TC ≤ 150°C.
Is KBP06G suitable for use with capacitive-input filters?
Yes, but with 20% current derating as specified in the datasheet. Capacitive-input configurations increase peak diode current and reduce conduction angle, raising thermal stress. At 1.5A rated current, limit continuous load to 1.2A when using bulk electrolytic input capacitors.
Does KBP06G meet automotive qualification standards?
No - KBP06G is not AEC-Q101 qualified. While it operates from –55°C to +150°C, it lacks PPAP documentation, IATF 16949 manufacturing evidence, and automotive-specific change control. For automotive applications, contact Diodes for AEC-Q101-compliant alternatives like the ABS20Q series.
How is polarity marked on the KBP06G package?
Polarity is indicated by a white band on the package body denoting the positive DC output (+) terminal. The AC input terminals (~) are unmarked but located adjacent to the banded end; the opposite end contains the negative DC output (–) terminal. Pin layout matches standard KBP mechanical outline (Diodes Doc # DS21203).
