KBP005G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBP005G is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for 50 V peak reverse voltage and 1.5 A average rectified current. This component is designed for through-hole mounting in 4-SIP KBP package configuration and operates across the temperature range of -65°C to 150°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when design requirements demand higher voltage ratings, increased current capacity, or alternative manufacturer sourcing while maintaining functional compatibility within the bridge rectifier category.

Substitute Part Grouping Explanation

Substitution logic for the KBP005G is determined by three primary parameters: diode type (single phase), mounting type (through hole), and package configuration (4-SIP KBP). Within these constraints, substitutes are grouped by voltage rating and current capacity.

Voltage-rated substitutes maintain the 1.5 A current specification while offering peak reverse voltages of 100 V, 200 V, 400 V, 600 V, 800 V, and 1 kV. These are manufactured by Diodes Incorporated and preserve identical forward voltage characteristics (1.1 V @ 1.5 A) and operating temperature range (-65°C ~ 150°C).

Current-rated substitutes from SMC Diode Solutions increase the average rectified current to 2 A while maintaining voltage ratings from 50 V to 400 V. These parts use a 4-ESIP package variant and operate across -55°C ~ 150°C, with REACH Affected status.

All substitutes maintain single-phase bridge rectifier topology, standard technology classification, and ROHS3 compliance.

Engineering Selection Recommendations

Diodes Incorporated KBP series (KBP01G through KBP10G) are direct voltage-rated substitutes for the KBP005G. These parts maintain identical current capacity (1.5 A), forward voltage characteristics, operating temperature range (-65°C ~ 150°C), and REACH Unaffected status. Selection among this series depends solely on required peak reverse voltage: 100 V, 200 V, 400 V, 600 V, 800 V, or 1 kV.

SMC Diode Solutions KBP series (KBP2005G, KBP201G, KBP202G, KBP204G) provide increased current capacity (2 A) at the cost of modified package configuration (4-ESIP versus 4-SIP) and REACH Affected status. Operating temperature minimum is reduced to -55°C. These parts are suitable for applications requiring higher current handling within the same voltage rating options.

All substitute parts maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity level. Product status is Active for all listed alternatives.

Frequently Asked Questions (FAQ)

Q: Can KBP01G replace KBP005G in my circuit? A: KBP01G is a direct substitute if your circuit operates at or below 100 V peak reverse voltage. Both parts share identical 1.5 A current capacity, 1.1 V forward voltage, -65°C ~ 150°C operating range, and 4-SIP KBP package configuration. The higher voltage rating of KBP01G provides additional design margin without functional penalty.

Q: What is the difference between Diodes Incorporated and SMC Diode Solutions KBP parts? A: Diodes Incorporated KBP series (KBP01G-KBP10G) maintains 1.5 A current, -65°C minimum operating temperature, and 4-SIP package. SMC Diode Solutions KBP series increases current to 2 A, reduces minimum operating temperature to -55°C, and uses 4-ESIP package. SMC parts also carry REACH Affected status versus REACH Unaffected for Diodes Incorporated.

Q: Can I use KBP2005G (2 A) instead of KBP005G (1.5 A)? A: KBP2005G is functionally compatible for 50 V applications requiring higher current capacity. However, the package changes from 4-SIP to 4-ESIP, operating temperature minimum shifts from -65°C to -55°C, and REACH status changes to Affected. Verify PCB layout compatibility with the 4-ESIP package before substitution.

Q: Which substitute should I select for a 600 V application? A: KBP06G is the specified part for 600 V peak reverse voltage at 1.5 A. It maintains all electrical and thermal characteristics of the KBP005G while providing the required voltage rating.

Q: Are all these parts through-hole mounted? A: Yes. KBP01G through KBP10G use 4-SIP KBP through-hole package. KBP2005G, KBP201G, KBP202G, and KBP204G use 4-ESIP through-hole package. Both package types are through-hole configurations suitable for PCB insertion.
