SBS34HREG Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The SBS34HREG is a single-phase bridge rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications. This component operates at 40 V peak reverse voltage with a 3 A average rectified current rating. The part is classified as Active product status and carries AEC-Q101 automotive qualification, making it suitable for automotive-grade applications requiring reliable rectification in power supply circuits.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter range. Alternative packaging configurations of the same base product may be required due to inventory availability, supply chain considerations, or specific assembly requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SBS34HREG is determined by equivalence across the following critical parameters:

Electrical Performance Criteria:

• Voltage - Peak Reverse (Max): 40 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 500 mV @ 3 A
• Current - Reverse Leakage @ Vr: 500 µA @ 40 V

Mechanical & Environmental Criteria:

• Diode Type: Single Phase
• Technology: Standard
• Operating Temperature Range: -55°C to 150°C (TJ)
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing

Compliance & Quality Criteria:

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts maintain identical electrical specifications and environmental ratings. Packaging configuration differences (such as Tape & Reel versus bulk packaging) do not affect electrical or mechanical compatibility when the base product number, case style, and mounting type remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both the SBS34HREG and SBS34 are Active product status components manufactured by Taiwan Semiconductor Corporation with identical electrical and mechanical specifications. Selection between these parts is based on packaging and supply requirements rather than functional performance.

SBS34HREG Selection Criteria:

• Bulk packaging configuration
• Current inventory: 957 Pcs New Original In Stock
• Applications requiring standard packaging format

SBS34 Selection Criteria:

• Tape & Reel (TR) packaging configuration
• Current inventory: 11,400 Pcs New Original In Stock
• High-volume production assembly requiring automated handling
• Applications with extended supply chain requirements

Both parts maintain AEC-Q101 automotive qualification, ROHS3 compliance, and identical electrical performance across the specified operating temperature range of -55°C to 150°C (TJ). The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either configuration.

Frequently Asked Questions (FAQ)

Q: Can SBS34 (Tape & Reel) be used as a direct replacement for SBS34HREG (Bulk)?

A: Yes. Both parts share identical electrical specifications, mechanical dimensions, and environmental ratings. The difference is packaging configuration only. SBS34 in Tape & Reel format is suitable for automated assembly processes, while SBS34HREG in bulk packaging is suitable for manual or semi-automated handling.

Q: Are there any electrical performance differences between SBS34HREG and SBS34?

A: No. Both parts have identical electrical characteristics: 40 V peak reverse voltage, 3 A average rectified current, 500 mV forward voltage drop at 3 A, and 500 µA reverse leakage current at 40 V.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both SBS34HREG and SBS34 carry AEC-Q101 automotive qualification and are classified as Automotive grade components.

Q: What is the operating temperature range for these bridge rectifiers?

A: Both parts operate across -55°C to 150°C junction temperature (TJ), suitable for automotive and industrial applications requiring extended temperature performance.

Q: Are there moisture sensitivity concerns with either part?

A: No. Both parts have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Q: Which packaging format should be selected for high-volume production?

A: SBS34 in Tape & Reel (TR) configuration is recommended for high-volume production due to compatibility with automated pick-and-place assembly equipment. Current inventory of 11,400 Pcs supports extended production runs.

Q: Are both parts RoHS compliant?

A: Yes. Both SBS34HREG and SBS34 are ROHS3 Compliant and REACH Unaffected, meeting environmental regulatory requirements.

Q: What is the package style for both parts?

A: Both parts use 4-SMD, Gull Wing package configuration with ABS supplier device package designation, suitable for surface mount PCB assembly.
