Product details
Overview
KBP202G from Diodes Incorporated is a 2.0A standard recovery bridge rectifier with 200V peak repetitive reverse voltage (VRRM), 1.1V max forward voltage at 2A, and 5µA max reverse leakage at 25°C. It features glass-passivated die construction, 1,500VRMS case dielectric strength, and is optimized for AC/DC power conversion in compact PCB-mounted power supplies.
For engineers reviewing the KBP202G datasheet, KBP202G pinout, KBP202G application, or KBP202G equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (RθJC = 14°C/W), surge rating (65A IFSM), and UL recognition (E95060) for safety-compliant designs.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a molded KBP package with tin-plated leads. Its standard recovery characteristic (trr not specified, consistent with non-fast-recovery classification) supports 50/60Hz line-frequency operation without commutation-induced ringing.
Designed for resistive or inductive loads, it requires 20% current derating under capacitive loading. Thermal performance is defined with mounting on a 75mm × 75mm × 1.6mm copper heatsink, enabling reliable 2.0A continuous conduction at TC = +105°C.
Key Specifications

| VRRM | 200 V - Withstands peak reverse line transients up to 200V without breakdown |
| IO @ TC=105°C | 2.0 A - Continuous average output current capability at junction temperature limit |
| VF Max @ 2A | 1.1 V - Total forward drop across two series diodes in conduction path |
| IFSM (8.3ms) | 65 A - Surge withstand for single half-sine AC line fault events |
| IR Max @ 25°C | 5 µA - Low leakage preserves efficiency in high-impedance hold-up circuits |
| RθJC | 14 °C/W - Enables direct heatsink attachment for thermal management |
| UL File No. | E95060 - Certified as Recognized Component for end-equipment safety compliance |

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) | Same KBP package, 200V VRRM, but 1.05V VF @ 2A (slightly lower conduction loss) | Higher IFSM (70A) but no UL recognition | Preferred where surge margin > safety certification; verify creepage/clearance compliance separately |
| KBU2B (Comchip) | Same 200V/2A rating, 1.1V VF, but RθJC = 16°C/W (2°C/W higher thermal resistance) | RoHS compliant but not UL recognized | Acceptable for cost-sensitive, non-certified consumer products with adequate heatsinking |
Compared with GBU2K and KBU2B, KBP202G uniquely combines UL E95060 recognition, 14°C/W thermal resistance, and Diodes' validated manufacturing in IATF 16949 facilities-making it optimal for safety-critical, thermally constrained, or automotive-adjacent industrial designs.

FAQ
What is the maximum operating temperature for KBP202G?
KBP202G has a junction-to-case thermal resistance of 14°C/W and is rated for continuous operation at TC = +105°C. Its operating temperature range spans −55°C to +150°C, with derating required above +105°C case temperature per the forward current derating curve in DS21205.
Is KBP202G suitable for use in automotive applications?
KBP202G itself is not AEC-Q101 qualified, but Diodes offers automotive-grade variants (e.g., KBP202G-A) with PPAP capability and IATF 16949 manufacturing. For non-automotive applications, its UL recognition and 150°C max TJ support under-hood-adjacent industrial use with proper thermal design.
How does the KBP package differ from KBPC or GBU packages?
The KBP package is a 4-pin, single-in-line (SIP) molded plastic housing measuring ~14.5 × 10.4 × 3.5 mm. Unlike KBPC (larger, with metal heat sink tab) or GBU (bulkier, higher IFSM), KBP prioritizes PCB footprint efficiency and UL compliance over ultra-high surge rating or bolt-on heatsinking.
Can KBP202G replace KBP201G in a 100V design?
No-KBP201G is rated for 100V VRRM while KBP202G is rated for 200V. Substituting a higher-VRRM part is generally safe electrically, but mechanical fit and thermal behavior must be verified. However, KBP202G may exhibit slightly higher VF due to process optimization for higher voltage, potentially affecting efficiency in low-voltage designs.
