Product details
Overview
KBP10G from Diodes Incorporated is a 1.5A, 1000V standard recovery bridge rectifier in KBP package, featuring 1.1V max forward voltage at 1.5A, 5µA max reverse leakage at 25°C, 40A non-repetitive surge rating, and 1500VRMS dielectric strength-used for AC/DC conversion in offline power supplies and industrial control power stages.
For engineers reviewing the KBP10G datasheet, KBP10G pinout, KBP10G application, or KBP10G equivalent, key selection criteria include peak reverse voltage (1000V), average output current (1.5A), thermal resistance (18°C/W), surge capability (40A), and UL recognition (E95060) for safety-compliant designs.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a monolithic KBP package with glass-passivated junctions. It operates across –55°C to +150°C junction temperature and supports 60Hz resistive/inductive loads without derating-capacitive loads require 20% current derating.
The device delivers 1.5A average rectified output at TC = +105°C, withstands 1000V repetitive peak reverse voltage, and exhibits low 20pF typical junction capacitance-enabling stable performance in line-frequency rectification with minimal switching noise coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse voltage the bridge can block without breakdown |
| IO | 1.5 A @ TC = +105°C - Continuous DC output current under heatsink-mounted thermal condition |
| VF Max | 1.1 V @ IF = 1.5A - Forward voltage drop per conducting path, defining conduction loss at rated load |
| IR Max | 5 µA @ VR = 1000V, TA = +25°C - Reverse leakage current limiting standby power loss and thermal runaway risk |
| IFSM | 40 A (8.3ms half-sine) - Surge current handling for inrush and transient overload protection |
| RθJC | 18 °C/W - Thermal resistance from junction to case, used to calculate heatsink requirements |
| VB | 1000 V @ IR = 5µA - Measured breakdown voltage confirming VRRM rating compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU10K (ON Semiconductor) | Same 1000V VRRM, 1.5A IO, but GBU package (larger footprint, higher RθJC = 25°C/W) | Requires larger PCB area and more thermal margin; lacks UL E95060 listing | Choose when legacy GBU layout compatibility is required and UL recognition is not mandated |
| W10 (Vishay) | 1000V VRRM, 1.5A IO, but WOB package; VF = 1.05V (slightly lower conduction loss) | Higher surge rating (50A), but no UL recognition and wider VF tolerance (±0.15V) | Prefer where peak efficiency matters most and safety certification is handled externally |
Compared with GBU10K and W10, KBP10G offers superior thermal performance (18°C/W vs. ≥25°C/W), mandatory UL recognition for end-product compliance, and optimized footprint for space-constrained PCBs-making it ideal for certified industrial and outdoor power supplies.

FAQ
What is the maximum allowable case temperature for continuous operation of KBP10G?
The KBP10G is rated for 1.5A average output current at TC = +105°C, meaning its case must not exceed +105°C during sustained operation. Exceeding this temperature requires current derating per the datasheet's thermal curves. The junction temperature limit remains –55°C to +150°C, so proper heatsinking is essential to maintain safe TC.
Does KBP10G support capacitive-input filter configurations?
No-KBP10G requires 20% current derating when used with capacitive-input filters due to increased peak currents and thermal stress. Its design targets resistive or inductive loads at 60Hz. For capacitor-input applications, consider fast-recovery or ultrafast bridges with higher IFSM and lower Qrr, or add inrush limiting circuitry.
Is KBP10G qualified for automotive applications?
KBP10G is not AEC-Q101 qualified. While it operates from –55°C to +150°C, Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing-available only upon direct request. Standard KBP10G is intended for industrial, commercial, and lighting applications.
How is polarity identified on the KBP10G package?
Polarity is marked directly on the top surface of the KBP package: "+" denotes the positive DC output terminal, "–" indicates the negative DC output terminal, and the two AC input terminals are unmarked but located at opposite ends of the row. The marking aligns with industry-standard KBP layout-confirmed by Diodes' package outline drawing DS21203 Rev. 13-2.
