RYBS30M Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The RYBS30M is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 1000V peak reverse voltage and 3A average rectified current. This surface mount component operates across a temperature range of -55°C to 150°C and is classified as Active product status with full RoHS3 compliance. Bridge rectifiers of this specification are essential in power supply circuits, industrial control systems, and AC-to-DC conversion applications where standard recovery characteristics and moderate current handling are required. Substitute parts become necessary when primary inventory is unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified manufacturers is needed.

Substitute Part Grouping Explanation

Substitution of the RYBS30M is permissible with components that maintain electrical and mechanical equivalence across all critical parameters. The substitution logic is based on the following criteria:

Electrical Equivalence Requirements:

• Peak reverse voltage rating of 1000V (minimum)
• Average rectified current rating of 3A (minimum)
• Forward voltage drop not exceeding 1.3V at rated current
• Reverse leakage current of 5µA or less at 1000V
• Single-phase bridge rectifier topology
• Standard recovery technology classification

Mechanical Equivalence Requirements:

• Surface mount mounting type
• 4-SMD package with flat leads configuration
• Compatible footprint and lead spacing

Compliance Requirements:

• RoHS3 compliance status
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected classification
• Active product status

The RDBF310-13 manufactured by Diodes Incorporated satisfies all electrical, mechanical, and compliance criteria for direct substitution with the RYBS30M.

Parameter Comparison

Engineering Selection Recommendations

The RDBF310-13 from Diodes Incorporated is a direct electrical and mechanical equivalent to the RYBS30M. Both components share identical voltage and current ratings, matching forward voltage characteristics, and equivalent reverse leakage specifications. Both maintain the same operating temperature range and surface mount 4-SMD package configuration.

Selection between these components should be based on:

Availability and Lead Time: The RDBF310-13 currently maintains higher inventory levels (4250 pcs) compared to the RYBS30M (2269 pcs), making it suitable for applications requiring immediate procurement or large-volume orders.

Manufacturer Qualification: Both manufacturers maintain Active product status with full RoHS3 compliance and REACH Unaffected classification, ensuring regulatory compliance across industrial and commercial applications.

Supply Chain Continuity: Maintaining qualified substitutes from multiple manufacturers (Taiwan Semiconductor Corporation and Diodes Incorporated) provides design flexibility and reduces single-source dependency in production environments.
