Product details
Overview
KBP306G from Diodes Incorporated is a 3.0A standard recovery bridge rectifier in KBP package, rated for 600V peak repetitive reverse voltage (VRRM), 1.1V max forward voltage at 3A, and 5μA max reverse leakage at 25°C. It delivers full-wave AC-to-DC conversion in compact PCB-mount designs for LED drivers, AC/DC power supplies, and home appliance power stages.
For engineers reviewing the KBP306G datasheet, KBP306G pinout, KBP306G application, or KBP306G equivalent, key selection criteria include VRRM rating, thermal resistance (RθJC = 10°C/W with heatsink), surge capability (90A @ 8.3ms), and RoHS-compliant tin-plated leads suitable for automated soldering.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a monolithic molded plastic KBP package with glass-passivated die construction. It supports resistive/inductive loads at 60Hz and requires 20% current derating for capacitive loads.
Thermal performance is defined by junction-to-case (10°C/W with heatsink), junction-to-lead (12°C/W), and junction-to-ambient (30°C/W) resistances. Reverse breakdown voltage is guaranteed ≥600V per element, with total capacitance of 35pF at 4V DC and 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage per diode leg; defines safe AC input range up to ~420V RMS |
| IO (TC=105°C) | 3.0 A - Average rectified output current with heatsink; sets continuous DC load capability |
| VF (IF=3A, TJ=25°C) | 1.1 V max - Forward voltage drop per diode; determines conduction loss and thermal rise at full load |
| IR (VR=VRRM, TJ=25°C) | 5 μA max - Reverse leakage current; critical for low-power standby efficiency and high-impedance hold-up |
| IFSM (8.3ms) | 90 A - Non-repetitive surge current rating; enables robust startup into capacitive or motor loads |
| RθJC | 10 °C/W - Junction-to-case thermal resistance with heatsink; guides minimum heatsink sizing for thermal management |
| CT (VR=4V, f=1MHz) | 35 pF - Total capacitance per diode element; affects EMI filtering and high-frequency switching behavior |

Applications
| LED Lighting Power Supply | AC/DC Adapter for Office Equipment |
|---|---|
Use Scenario: Off-line LED driver converting 120/230V AC to DC bus for constant-current regulation. IC Role / Device Role / Timing Role: Full-wave bridge rectifier providing unregulated DC input to PFC or buck converter stage. Use Value: 600V VRRM safely handles 230VAC mains with margin; low VF minimizes conduction loss in thermally constrained lamp housings. | Use Scenario: Compact wall-wart adapter powering printers, monitors, or VoIP phones. IC Role / Device Role / Timing Role: Primary-side AC-to-DC conversion before transformer isolation and linear/switching regulation. Use Value: KBP package enables high-density layout; 90A IFSM withstands repeated plug-in surges without degradation. |
| Home Appliance Control Board | Telecom Power Interface |
Use Scenario: Embedded control board in washing machines or microwaves requiring auxiliary 12V/24V supply. IC Role / Device Role / Timing Role: Mains-fed rectification feeding linear regulator or small SMPS for MCU and sensor rails. Use Value: UL recognition simplifies system-level safety approval; glass passivation ensures reliability in humid environments. | Use Scenario: Low-power AC-powered telecom interface module (e.g., DSL modem, gateway). IC Role / Device Role / Timing Role: Input-stage rectification prior to DC-DC conversion and PoE controller circuitry. Use Value: 5μA IR at 25°C reduces standby power draw; 35pF CT limits high-frequency noise coupling into sensitive analog sections. |
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 at 3A; slightly lower RθJA (35°C/W vs 40°C/W) | Identical use in AC/DC front-ends; tighter VF spec improves efficiency at light loads | Prefer when optimizing for low-loss operation below 2A average current |
| KBL06 (Diotec) | 600V VRRM, 3A IO, but KBL package (larger footprint); higher IFSM (100A) | Requires PCB layout change; better suited for industrial equipment with higher surge exposure | Choose only if mechanical redesign is acceptable and surge margin >90A is required |
Compared with GBU6K and KBL06, KBP306G offers balanced thermal performance (10°C/W RθJC), UL recognition, and proven field reliability in consumer-grade LED and adapter designs-making it optimal for cost-sensitive, high-volume PCB assemblies where footprint and certification matter.

FAQ
What is the maximum operating temperature for KBP306G?
KBP306G has an operating junction temperature range of –55°C to +150°C. Its maximum average rectified output current drops to 1.9A at TC = +105°C without heatsink, and full 3.0A rating is maintained only when mounted on a heatsink that keeps case temperature ≤105°C.
Can KBP306G be used in automotive applications?
KBP306G is not AEC-Q200 qualified and lacks automotive-specific change control or PPAP documentation. While it may function in non-safety-critical 12V accessory circuits, Diodes recommends contacting their automotive team for AEC-qualified alternatives like the ABS210Q or GBU6J-A.
How does the KBP package differ from KBPC or GBU packages?
KBP is a 4-pin, single-in-line (SIP) molded plastic package with 14.5mm × 10.4mm footprint and 4.0mm height. KBPC is larger (20mm × 14mm), while GBU uses a rectangular 20mm × 14mm body with different lead spacing-KBP enables higher PCB density and automated placement compatibility.
Is KBP306G compatible with lead-free reflow processes?
Yes-KBP306G features a lead-free, RoHS-compliant tin-plated finish and is qualified for standard Pb-free reflow profiles (peak temperature up to 260°C). Its molded plastic body meets UL 94V-0 flammability rating and withstands multiple thermal cycles without delamination.
