SS1FL3-M3/I Equivalent & Substitute Parts

Part Overview

The SS1FL3-M3/I is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, classified within the eSMP® series. This surface mount component operates at 30 V DC reverse voltage with 1 A average rectified current capacity and is housed in a DO-219AB (SMF) package. The part is Active in product status and ROHS3 compliant, making it suitable for modern electronic applications requiring fast recovery rectification characteristics.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative packaging formats and automotive-grade variants are available to accommodate different procurement, supply chain, and application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS1FL3-M3/I are identified based on strict electrical and mechanical parameter equivalence. All substitute candidates maintain identical specifications across the following critical parameters:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 480 mV @ 1 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 200 µA @ 30 V
• Capacitance @ Vr, F: 130 pF @ 4V, 1MHz
• Package / Case: DO-219AB (SMF)
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Schottky
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitution differences are limited to packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and automotive qualification status. These variations do not affect electrical performance or thermal characteristics and are determined by supply chain availability and application requirements.
