Product details
Overview
KBP310G from Diodes Incorporated is a 3.0A standard recovery bridge rectifier in KBP package, rated for 1000V 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 lighting power supplies and office equipment.
For engineers reviewing the KBP310G datasheet, KBP310G pinout, KBP310G application, or KBP310G equivalent, key selection criteria include VRRM rating, surge current capability (90A @ 8.3ms), thermal resistance (RθJC = 10°C/W with heatsink), and UL recognition (E95060) for safety-critical AC/DC front-end designs.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a common anode–common cathode configuration. Its glass-passivated die construction ensures stable reverse characteristics across -55°C to +150°C operating range and supports non-repetitive surge currents up to 90A (8.3ms half-sine).
Designed for resistive or inductive loads at 60Hz, it requires 20% average current derating under capacitive load conditions. Thermal performance is defined with and without heatsink: RθJA is 30°C/W (with 30mm × 30mm × 1mm Cu plate) and 40°C/W (no heatsink).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse voltage per diode element; defines safe AC input voltage ceiling (e.g., 700V RMS) |
| IO (TC = +105°C) | 3.0 A - Average rectified output current with heatsink; sets continuous DC output capability |
| VF (IF = 3A, TJ = +25°C) | 1.1 V max - Forward voltage drop per diode; determines conduction loss (≈3.3W total bridge loss at 3A) |
| IR (VR = VRRM, TJ = +25°C) | 5 μA max - Reverse leakage per element; critical for low-power standby efficiency and thermal stability |
| IFSM (8.3ms, TJ = +25°C) | 90 A - Non-repetitive surge current rating; enables robust startup and transient handling in unregulated supplies |
| RθJC | 10 °C/W - Junction-to-case thermal resistance with heatsink; enables thermal design using measured case temperature |
| UL File # | E95060 - Recognized for safety compliance; required for end-product certification in North America |

Use Value: 90A IFSM withstands repeated plug-in surges; 30°C/W RθJA allows thermal management without heatsink at ≤1.9A load. |
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 and 3A IO, but GBU package (larger footprint, higher RθJA = 45°C/W) | Less space-constrained designs where PCB area is available and heatsinking is passive-only | Select when mechanical compatibility with legacy GBU footprints is required |
| KBL10 | 1000V VRRM, 3.5A IO, but KBL package (4-pin inline, lower VF ≈ 1.05V typ) | Higher-current applications needing margin or lower conduction loss at elevated temperatures | Choose when IO derating headroom or thermal margin is critical in high-ambient environments |
Compared with KBP310G, GBU10K offers identical electrical ratings but less compact packaging, while KBL10 provides higher current capacity and slightly lower VF-both require board layout changes but enable trade-offs in thermal design and footprint density.

FAQ
What is the maximum average output current for KBP310G without a heatsink?
KBP310G delivers 1.9A average rectified output current at TC = +105°C without a heatsink, as specified in the Absolute Maximum Ratings table. This value assumes free-air convection cooling and accounts for thermal derating above +25°C ambient. Operation beyond this limit risks junction overheating and premature failure.
Does KBP310G meet automotive qualification standards?
KBP310G is not qualified to AEC-Q101 or other automotive stress test standards. Diodes Incorporated explicitly states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing-none of which apply to the standard KBP310G. It is intended for industrial, consumer, and telecom applications only.
How does the 1000V PRV rating relate to actual operating voltage?
The 1000V peak repetitive reverse voltage (VRRM) specifies the maximum instantaneous reverse voltage each internal diode can block repeatedly. For 264VAC RMS input, peak line voltage is ~373V; the 1000V rating provides >2.6× safety margin against transients, line surges, and ringing, satisfying IEC 61000-4-5 Level 3 immunity requirements.
Can KBP310G be used in capacitive-input filter configurations?
Yes, but with 20% average current derating per the datasheet. In capacitive-input (choke-input) filters, peak diode conduction angle narrows, increasing RMS current stress. For a nominal 3.0A rating, limit continuous DC output to 2.4A to maintain reliability and avoid thermal runaway under sustained load.
