KBP208 Bridge Rectifier Single Phase 800V 2A Equivalent & Substitute Parts

Part Overview

The KBP208 is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 800V peak reverse voltage and 2A average rectified current. This component is designed for through-hole mounting applications requiring standard bridge rectification in industrial and power conversion circuits. The part maintains active product status with 2300 units in current inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter range. Alternative sources become necessary to address supply chain requirements, inventory availability, or design flexibility without compromising circuit performance.

Substitute Part Grouping Explanation

Substitution eligibility for the KBP208 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Voltage - Peak Reverse (Max): 800 V
• Current - Average Rectified (Io): 2 A
• Diode Type: Single Phase
• Technology: Standard
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole
• Package / Case: KBP form factor
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Requirements:

• RoHS Status: RoHS Compliant or equivalent
• ECCN: EAR99

The KBP208G from SMC Diode Solutions satisfies all electrical and mechanical equivalence criteria, maintaining identical peak reverse voltage, average rectified current, forward voltage characteristics, and through-hole KBP packaging. Both parts operate within overlapping temperature ranges and meet applicable regulatory compliance standards.

Parameter Comparison

Engineering Selection Recommendations

KBP208 (GeneSiC Semiconductor): Select this part when GeneSiC Semiconductor sourcing is specified or preferred. The component maintains active product status with established inventory levels (2300 units). RoHS compliance and EAR99 classification support standard procurement workflows.

KBP208G (SMC Diode Solutions): This substitute part provides equivalent electrical performance with enhanced reverse leakage characteristics (5 µA @ 800 V versus 10 µA @ 50 V) and extended lower operating temperature limit (-55°C versus -50°C). ROHS3 compliance and significantly higher inventory availability (19035 units) support supply chain flexibility. The 4-ESIP package variant maintains KBP form factor compatibility for through-hole mounting applications.

Both parts satisfy identical circuit requirements for single-phase bridge rectification at 800V/2A ratings. Selection between KBP208 and KBP208G depends on supplier preference, inventory requirements, and specific thermal or leakage performance criteria within the stated operating envelope.

Frequently Asked Questions (FAQ)

Q: Can KBP208G replace KBP208 in existing designs?

A: Yes. Both parts maintain identical electrical ratings (800V peak reverse voltage, 2A average rectified current, 1.1V forward voltage @ 2A) and through-hole KBP packaging. The KBP208G operates across a compatible temperature range (-55°C to 150°C) and meets equivalent RoHS compliance standards.

Q: What are the differences between KBP208 and KBP208G?

A: The primary differences are manufacturer (GeneSiC Semiconductor versus SMC Diode Solutions), reverse leakage current measurement conditions (10 µA @ 50V versus 5 µA @ 800V), lower operating temperature limit (-50°C versus -55°C), and package designation (4-SIP versus 4-ESIP). Both maintain KBP form factor compatibility.

Q: Are there package compatibility concerns between 4-SIP and 4-ESIP variants?

A: Both 4-SIP and 4-ESIP designations reference KBP form factor through-hole packages. Pin configuration and footprint compatibility are maintained for standard bridge rectifier applications. Verify PCB layout against specific package drawings if custom footprints are used.

Q: Which part should be selected for new designs?

A: Selection depends on supplier availability and design requirements. KBP208G offers higher inventory levels and extended lower temperature rating. KBP208 maintains established GeneSiC Semiconductor sourcing. Both parts satisfy identical circuit performance specifications for 800V/2A single-phase bridge rectification.

Q: Do both parts meet regulatory compliance requirements?

A: Yes. KBP208 is RoHS Compliant; KBP208G is ROHS3 Compliant. Both carry EAR99 ECCN classification and MSL 1 (Unlimited) moisture sensitivity rating, supporting standard procurement and handling procedures.
