KBL406G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBL406G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, designed for applications requiring full-wave rectification at 800 V peak reverse voltage with 4 A average rectified current capacity. This component operates across an industrial temperature range of -55°C to 150°C and is packaged in a through-hole 4-SIP KBL configuration. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified based on electrical performance parameters and mechanical compatibility within the bridge rectifier category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBL406G bridge rectifier is determined by equivalence across the following critical parameters:

Electrical Performance Criteria:

• Voltage - Peak Reverse (Max): 800 V minimum
• Current - Average Rectified (Io): 4 A minimum
• Voltage - Forward (Vf) (Max) @ If: 1.1 V or lower at 4 A
• Current - Reverse Leakage @ Vr: 10 µA or lower at 800 V

Mechanical & Environmental Criteria:

• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Package / Case: 4-SIP, KBL configuration
• Operating Temperature Range: -55°C to 150°C (TJ) minimum

Compliance & Regulatory Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Parts meeting all specified parameters within these categories are classified as direct equivalents and substitutes for the KBL406G.

Engineering Selection Recommendations

The KBL406G maintains Active product status with full regulatory compliance under ROHS3 and REACH standards. Selection of equivalent bridge rectifier components for the KBL406G should prioritize parts with identical electrical specifications (800 V peak reverse voltage, 4 A average rectified current, 1.1 V forward voltage drop, and 10 µA reverse leakage) and matching mechanical configuration (through-hole 4-SIP KBL package). Parts meeting these criteria ensure direct functional interchangeability without circuit redesign or thermal management modifications. Compliance certifications (ROHS3, REACH Unaffected, MSL 1) must be verified for applications subject to regulatory requirements. The operating temperature range of -55°C to 150°C establishes the thermal envelope for component selection in industrial and extended-temperature applications.

Frequently Asked Questions (FAQ)

Q: What defines a direct substitute for the KBL406G bridge rectifier?

A: A direct substitute must match all electrical parameters (800 V peak reverse voltage, 4 A average rectified current, 1.1 V maximum forward voltage at 4 A, and 10 µA reverse leakage at 800 V), maintain the same through-hole 4-SIP KBL package configuration, support the -55°C to 150°C operating temperature range, and comply with ROHS3 and REACH standards.

Q: Can bridge rectifiers with higher voltage or current ratings substitute for the KBL406G?

A: Bridge rectifiers with higher voltage or current ratings are electrically compatible for direct substitution in the KBL406G application. However, they must maintain the identical 4-SIP KBL through-hole package footprint and preserve the specified forward voltage and reverse leakage characteristics to ensure circuit performance equivalence.

Q: What is the significance of the 4-SIP KBL package specification?

A: The 4-SIP KBL package is a through-hole configuration with four pins arranged in a single inline pattern. This mechanical specification determines PCB footprint compatibility and mounting method. Substitutes must use the identical package to ensure direct board-level interchangeability without layout modifications.

Q: Are there packaging alternatives to the through-hole 4-SIP KBL configuration?

A: The KBL406G is specified exclusively in the through-hole 4-SIP KBL package. Substitutes must maintain this same package type. Surface-mount or alternative package configurations are not considered equivalent substitutes for this component.

Q: How does the -55°C to 150°C operating temperature range affect substitute selection?

A: The operating temperature range defines the thermal environment in which the bridge rectifier functions. Substitute parts must support the full -55°C to 150°C junction temperature range to maintain electrical performance and reliability across the specified application conditions.

Q: What compliance certifications are required for substitute parts?

A: Substitute parts must maintain ROHS3 compliance and REACH Unaffected status. These certifications confirm adherence to hazardous substance restrictions and environmental regulations applicable to the KBL406G. Moisture Sensitivity Level 1 (Unlimited) indicates no moisture-related handling restrictions.
