S1JAL Equivalent & Substitute Parts

Part Overview

The S1JAL is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 1 A average rectified current in a surface mount Thin SMA package. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and packaging specifications are required for design flexibility, inventory management, or supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the S1JAL is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Current - Reverse Leakage @ Vr: 1 µA @ 600 V
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Capacitance @ Vr, F: 8 pF @ 4V, 1MHz
• Package / Case: DO-221AC, SMA Flat Leads
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

The S1JALH meets all specified electrical and mechanical parameters and is therefore classified as a parametric equivalent. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical base product number S1J.

Parameter Comparison
