MB8S-TP Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The MB8S-TP is a single-phase bridge rectifier diode manufactured by Micro Commercial Co, rated for 800 V peak reverse voltage with 500 mA average rectified current. This component is designed for surface mount applications in TO-269AA (4-BESOP) package configuration. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1), making it suitable for industrial and commercial rectification circuits requiring high voltage performance.

Substitute parts are identified based on matching electrical characteristics and mechanical compatibility within the single-phase bridge rectifier category. Alternative sources and voltage-rated variants are available to support supply chain flexibility and application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MB8S-TP are categorized based on the following substitution criteria:

Parametric Equivalent (Full Compatibility):

• Identical voltage rating (800 V peak reverse)
• Identical current rating (500 mA average rectified)
• Identical forward voltage characteristics (1 V @ 400 mA)
• Identical reverse leakage (5 µA @ 800 V)
• Identical package (TO-269AA, 4-BESOP)
• Identical operating temperature range or compatible range
• Active product status with equivalent compliance certifications

Voltage-Reduced Substitutes (Conditional Use):

• Lower peak reverse voltage ratings (200 V, 600 V)
• Identical current rating (500 mA average rectified)
• Identical forward voltage and reverse leakage characteristics
• Identical package and mounting type
• Suitable only for applications where the lower voltage rating meets circuit requirements

All substitute parts maintain single-phase bridge rectifier topology, surface mount configuration, and RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

MB8S (Fairchild Semiconductor) is the primary parametric equivalent for the MB8S-TP. Both parts share identical voltage (800 V), current (500 mA), forward voltage (1 V @ 400 mA), and reverse leakage (5 µA @ 800 V) specifications. The operating temperature range differs minimally (-50°C to 150°C versus -55°C to 150°C), with the MB8S suitable for applications not requiring the extended lower temperature limit. Both maintain active product status. RoHS3 compliance and MSL ratings are not specified for the MB8S; verification against specific procurement requirements is necessary.

MB6S-E3/80 (Vishay General Semiconductor) provides a voltage-reduced alternative rated at 600 V peak reverse. This substitute is applicable only to circuits where the maximum operating voltage does not exceed 600 V. All other electrical parameters (500 mA current, 1 V forward voltage, 5 µA reverse leakage) remain identical. The part maintains RoHS3 compliance, MSL 1 rating, and active product status.

MB2S-E3/45 (Vishay General Semiconductor) is a further voltage-reduced variant rated at 200 V peak reverse. This substitute is restricted to low-voltage applications where circuit requirements do not exceed 200 V. Electrical performance characteristics (500 mA current, 1 V forward voltage, 5 µA reverse leakage) match the main part. RoHS3 compliance and MSL 1 rating are maintained.

All substitute parts are packaged in TO-269AA (4-BESOP) configuration and are surface mount compatible with the MB8S-TP footprint.

Frequently Asked Questions (FAQ)

Q: Can MB8S replace MB8S-TP in all applications?

A: MB8S is a parametric equivalent with identical electrical specifications (800 V, 500 mA, 1 V forward voltage, 5 µA reverse leakage). The operating temperature range is -50°C to 150°C compared to -55°C to 150°C for MB8S-TP. Substitution is valid for applications not requiring operation below -50°C. RoHS3 compliance status for MB8S should be confirmed with the supplier.

Q: When is MB6S-E3/80 suitable as a substitute?

A: MB6S-E3/80 is suitable only when the circuit design operates at or below 600 V peak reverse voltage. All other parameters (500 mA current, 1 V forward voltage, 5 µA reverse leakage) are identical. The part maintains RoHS3 compliance and MSL 1 rating. Applications requiring 800 V rating cannot use this substitute.

Q: Can MB2S-E3/45 be used in place of MB8S-TP?

A: MB2S-E3/45 is restricted to applications with maximum operating voltage of 200 V or less. Current, forward voltage, and reverse leakage specifications are identical to MB8S-TP. This substitute is not suitable for circuits designed for 800 V operation.

Q: Are all substitute parts in the same package?

A: Yes. MB8S-TP, MB8S, MB6S-E3/80, and MB2S-E3/45 are all packaged in TO-269AA (4-BESOP) configuration and are surface mount compatible. Footprint compatibility is maintained across all parts.

Q: What compliance certifications apply to substitute parts?

A: MB6S-E3/80 and MB2S-E3/45 are RoHS3 compliant with MSL 1 (Unlimited) rating. MB8S compliance certifications are not specified in available data and should be confirmed with Fairchild Semiconductor or the authorized distributor.

Q: Do all parts have the same operating temperature range?

A: MB8S-TP, MB6S-E3/80, and MB2S-E3/45 operate from -55°C to 150°C. MB8S operates from -50°C to 150°C. For applications requiring operation below -50°C, MB8S is not suitable.
