RS1A General Purpose Rectifier Diode 50V 1A SMA Equivalent & Substitute Parts

Part Overview

The RS1A is a general purpose rectifier diode manufactured by SMC Diode Solutions, rated for 50V DC reverse voltage and 1A average rectified current in a surface mount SMA (DO-214AC) package. This diode is designed for standard rectification applications requiring fast recovery characteristics. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory availability, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RS1A is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
• Reverse Recovery Time (trr): 150 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 50 V
• Capacitance @ Vr, F: 15 pF @ 4V, 1MHz

Mechanical & Environmental Criteria:

• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -65°C to 150°C
• Technology: Standard

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must match all electrical parameters, maintain identical package specifications, and satisfy the same environmental and compliance requirements. The RS1A-13-F from Diodes Incorporated meets these criteria as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The RS1A-13-F from Diodes Incorporated is a direct parametric equivalent to the RS1A from SMC Diode Solutions. Both parts are active products with identical electrical specifications, package configurations, and compliance certifications. Selection between these parts is based on availability, supply chain requirements, or design flexibility considerations rather than technical performance differences.

Both parts satisfy ROHS3 compliance requirements and carry unlimited moisture sensitivity rating (MSL 1), indicating no special handling or storage conditions are required. The identical operating temperature range (-65°C to 150°C) ensures thermal performance equivalence across all application environments.

Frequently Asked Questions (FAQ)
