KBP06M Bridge Rectifier Single Phase 600V 1.5A Equivalent & Substitute Parts

Part Overview

The KBP06M is a single-phase bridge rectifier manufactured by onsemi, rated for 600V peak reverse voltage and 1.5A average rectified current. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The KBP06M operates across a wide temperature range of -55°C to 165°C and is packaged in a 4-SIP KBPM through-hole configuration with unlimited moisture sensitivity rating.

Substitute Part Grouping Explanation

Substitution eligibility for the KBP06M is determined by the following critical parameters:

Voltage Rating: Peak reverse voltage must be 600V or higher to maintain electrical safety margins
Current Rating: Average rectified current must be 1.5A or higher to support circuit requirements
Diode Type: Single-phase bridge rectifier configuration only
Technology: Standard rectifier technology
Mounting Type: Through-hole configuration required for mechanical compatibility
Package Form Factor: 4-SIP package family (KBPM, KBP, or D-44 variants)

Substitute parts are grouped into two categories based on these parameters:

Category A - Direct Voltage/Current Match (600V, ≥1.5A): Parts meeting or exceeding the exact voltage and current specifications with compatible packaging.

Category B - Higher Voltage Rating (≥600V, ≥1.5A): Parts with equal or higher voltage ratings and equal or higher current ratings, suitable for applications where the KBP06M specifications are minimum requirements.

Engineering Selection Recommendations

Primary Substitute - KBP06G (Diodes Incorporated)

The KBP06G is the most direct substitute for the obsolete KBP06M. It maintains identical voltage (600V) and current (1.5A) ratings with active product status and RoHS3 compliance. The forward voltage specification is marginally higher (1.1V @ 1.5A versus 1V @ 1A), which is acceptable for standard rectifier applications. The operating temperature range is slightly narrower (-65°C to 150°C versus -55°C to 165°C), requiring verification for applications operating above 150°C or below -65°C. The 4-SIP KBP package is mechanically compatible with the original KBPM footprint.

Secondary Substitute - VS-2KBP06 (Vishay General Semiconductor - Diodes Division)

The VS-2KBP06 provides 600V voltage rating with higher current capacity (2A versus 1.5A), offering design margin for current-limited applications. This part is active and RoHS3 compliant. The D-44 package is a 4-SIP through-hole configuration compatible with KBP footprints. The operating temperature range (-40°C to 150°C) is narrower than the original, requiring thermal verification for extended temperature applications.

Higher Voltage Alternative - VS-2KBP10 (Vishay General Semiconductor - Diodes Division)

The VS-2KBP10 rated at 1kV with 2A current capacity serves applications requiring voltage derating or higher safety margins. This part is active and RoHS3 compliant. Use only when circuit design permits higher voltage components without introducing unintended electrical characteristics.

Not Recommended - VS-2KBP02

The VS-2KBP02 is rated at only 200V peak reverse voltage, which is insufficient for the KBP06M's 600V specification. This part does not meet substitution criteria and should not be used as a replacement.

Frequently Asked Questions (FAQ)

Q: Can KBP06G directly replace KBP06M in all applications?

A: KBP06G is electrically compatible for most applications. Verify that your circuit operates within the KBP06G temperature range (-65°C to 150°C). If your design requires operation above 150°C or below -65°C, thermal analysis is required before substitution.

Q: What is the difference between the KBPM and KBP package designations?

A: Both KBPM and KBP are 4-SIP through-hole bridge rectifier packages families. The KBP06G uses the KBP designation while the original uses KBPM. These packages are mechanically and electrically compatible for standard PCB layouts.

Q: Why is VS-2KBP06 rated for 2A when KBP06M is only 1.5A?

A: The higher current rating provides additional design margin and thermal headroom. In applications drawing 1.5A or less, the VS-2KBP06 will operate at lower junction temperature than the KBP06M, extending component life. No circuit modification is required for substitution.

Q: Can I use VS-2KBP10 (1kV rated) instead of KBP06M (600V rated)?

A: Yes, if your circuit design permits. The higher voltage rating introduces no electrical incompatibility for 600V applications. However, verify that component selection does not conflict with other circuit design constraints or cost requirements.

Q: What does "obsolete" status mean for the KBP06M?

A: Obsolete status indicates the manufacturer has discontinued production. Existing inventory may be available from distributors, but long-term supply cannot be guaranteed. Substitution to active-status parts (KBP06G, VS-2KBP06, VS-2KBP10) ensures future availability and design continuity.

Q: Are all substitute parts RoHS compliant?

A: KBP06G and VS-2KBP06 are RoHS3 compliant. KBP206G compliance status is not applicable per manufacturer data. Verify RoHS requirements for your specific application and region before final part selection.
