Product details
Overview
KBP02G from Diodes Incorporated is a 200V, 1.5A 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 in AC/DC power supplies for industrial control panels.
For engineers reviewing the KBP02G datasheet, KBP02G pinout, KBP02G application, or KBP02G equivalent, key selection criteria include VRRM=200V, IO=1.5A, VF≤1.1V, IR≤5µA, and KBP package thermal resistance of 18°C/W for PCB-level thermal management.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a monolithic plastic package with glass-passivated junctions. It operates across -55°C to +150°C junction temperature and supports 60Hz resistive/inductive loads without derating.
Designed for line-frequency rectification, it delivers 1.5A average output current at TC=+105°C with 6.6A²s I²t fusing rating and 20pF typical junction capacitance-enabling stable performance in offline SMPS input stages and motor drive front-ends.
Key Specifications

| IO | 1.5 A - average rectified output current sustainable at TC = +105°C |
| VF Max | 1.1 V @ 1.5A - forward voltage drop limiting conduction loss in 120/240VAC input circuits |
| IR Max | 5 µA @ 25°C - low reverse leakage preserving efficiency in high-impedance hold-up networks |
| IFSM | 40 A - peak surge current handling capability during cold-start inrush events |
| RθJC | 18 °C/W - thermal resistance enabling direct heatsink mounting on 75×75mm Cu plate |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K (ON Semiconductor) | VRRM=200V, IO=2.0A, VF=1.1V, KBP-compatible footprint but GBU package (larger height) | Higher current rating allows margin in thermally constrained layouts | Select when board space permits taller profile and higher continuous current is required |
| W02M (Vishay) | VRRM=200V, IO=1.5A, VF=1.1V, same KBP package, but 1000VRMS isolation rating | Lower dielectric strength may require additional creepage/clearance design effort | Choose only if cost sensitivity outweighs safety margin needs in non-certified prototypes |
Compared with GBU2K and W02M, KBP02G offers optimal balance of certified 1500VRMS isolation, UL recognition, and standardized KBP footprint-making it preferred for production-grade industrial power supplies requiring regulatory compliance and thermal predictability.

FAQ
What is the maximum operating junction temperature for KBP02G?
The KBP02G has a specified operating junction temperature range of -55°C to +150°C. Its thermal resistance RθJC is 18°C/W, meaning that at 1.5A DC output with 1.1V forward drop (1.65W dissipation), junction-to-case temperature rise is ~29.7°C-well within limits when mounted on a 75mm × 75mm copper heatsink.
Can KBP02G be used in capacitive-input filter applications?
No-KBP02G must be derated by 20% for capacitive-load applications per datasheet guidance. For such designs, its average output current rating drops to 1.2A, and designers must verify peak diode current does not exceed 40A IFSM during startup, especially with large bulk capacitors.
Is KBP02G qualified for automotive use?
KBP02G is not AEC-Q101 qualified. While it operates across -55°C to +150°C, Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing-available only upon request and separate qualification.
How is polarity indicated on the KBP02G package?
Polarity is marked directly on the plastic body: "+" denotes the positive DC output terminal, "–" indicates the negative DC output/common return, and "~" symbols identify the two AC input terminals-visible adjacent to respective leads per the KBP outline drawing.
