Substitute Part Grouping Explanation

Substitution of the SS1P3L-E3/85A is determined by equivalence in the following critical parameters:

Primary Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 30 V
Voltage - Forward (Vf) (Max) @ If: 450 mV @ 1 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 200 µA @ 30 V
Package / Case: DO-220AA (SMP)
Operating Temperature - Junction: -55°C to 150°C
Technology: Schottky
Series: eSMP®

Current Rating Consideration: The SS1P3L-E3/85A specifies 1.5 A average rectified current. Substitute parts are grouped into two categories: those maintaining 1.5 A rating (full equivalents) and those rated at 1 A (reduced current capacity). Parts with 1 A rating operate within the same voltage and thermal envelope but with lower current handling capability.

Packaging Variants: Substitute parts are available in multiple packaging formats (Tape & Reel, Cut Tape) while maintaining identical electrical performance and DO-220AA case geometry.
