Product details
Overview
KBP005G from Diodes Incorporated is a 1.5A standard recovery bridge rectifier with 50V maximum repetitive peak reverse voltage (VRRM), 1.1V forward voltage drop at 1.5A, and 5µA maximum reverse leakage current at 25°C. It features glass passivated die construction, 1500VRMS case dielectric strength, and is rated for 40A non-repetitive surge current. It is used in AC/DC power supplies for consumer electronics and industrial control boards.
For engineers reviewing the KBP005G datasheet, KBP005G pinout, KBP005G application, or KBP005G equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (18°C/W junction-to-case), surge rating for inrush handling, and UL recognition for safety-compliant 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. It operates across –55°C to +150°C junction temperature and supports 60Hz resistive/inductive loads without derating; capacitive loads require 20% IO derating.
The device uses glass passivation for enhanced surface stability and reliability under humid or contaminated environments. Its 20pF typical junction capacitance and low IR support stable DC output filtering in offline SMPS front-ends and linear power supply inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Withstands 50V repetitive reverse voltage; suitable for 36VAC RMS input (≈51V peak) with safety margin |
| IO @ TC=105°C | 1.5 A - Continuous average output current when case temperature held at 105°C |
| VF @ 1.5A, 25°C | 1.1 V - Total forward drop across two series diodes in conduction path; determines conduction loss (1.65W @ 1.5A) |
| IR @ 50V, 25°C | 5 µA - Low reverse leakage preserves no-load efficiency and minimizes standby power loss |
| IFSM (8.3ms) | 40 A - Handles cold-start inrush surges in transformer-fed supplies without failure |
| RθJC | 18 °C/W - Enables thermal design with external heatsink; 30°C rise at 1.5A dissipation |
| VB @ IR=5µA | 50 V - Confirmed breakdown threshold aligns with VRRM rating under standardized test conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4A (ON Semiconductor) | Same KBP package, 50V VRRM, 1.5A IO, but VF = 1.05V typ (slightly lower loss); RθJC = 20°C/W | Marginally better conduction efficiency but higher thermal resistance reduces power handling at elevated TC | Select when optimizing for minimal conduction loss at TA < 60°C; verify heatsinking if operating near 105°C case limit |
| KBU4A (Comchip) | Identical VRRM, IO, VF (1.1V max), and RθJC (18°C/W); UL recognized (E170312), but IR = 10µA max at 25°C | Higher leakage may impact ultra-low-power standby performance in energy-sensitive designs | Acceptable where IR ≤ 10µA is sufficient; confirm compliance with IEC 62301 standby limits if applicable |
Compared with GBU4A and KBU4A, KBP005G offers balanced trade-offs: identical thermal performance to KBU4A, tighter IR spec than KBU4A, and lower RθJC than GBU4A-making it optimal for thermally constrained, safety-certified, and low-leakage applications.

FAQ
What is the maximum allowable case temperature for continuous operation of KBP005G?
The KBP005G is rated for continuous operation at a case temperature (TC) of up to +105°C, as specified in its maximum ratings table. At this temperature, it delivers its full 1.5A average rectified output current. Exceeding +105°C requires derating per the thermal characteristics curve; junction temperature must remain within –55°C to +150°C limits.
Can KBP005G be used in a 230VAC input application?
No - KBP005G has a 50V VRRM rating, making it unsuitable for 230VAC (peak ≈ 325V) input. It is designed for low-voltage AC inputs such as 12VAC, 24VAC, or 36VAC transformers. For 230VAC, select KBP06G (600V) or higher VRRM variants from the same KBP family.
Is KBP005G pin-compatible with other KBP-series rectifiers like KBP01G or KBP02G?
Yes - all KBP-series bridge rectifiers (KBP005G through KBP10G) share identical KBP package dimensions, pinout configuration, and terminal layout. Only VRRM and related breakdown parameters differ; mechanical and PCB footprint compatibility is maintained across the series.
Does KBP005G meet automotive qualification standards such as AEC-Q101?
No - KBP005G is not AEC-Q101 qualified. The datasheet explicitly states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing; standard KBP005G is intended for industrial and consumer applications. For automotive use, contact Diodes Incorporated for qualified alternatives.
