Substitute Part Grouping Explanation

Substitute parts for the STPS1150RL are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain constant across all equivalent devices:

• Voltage Rating: 150 V DC reverse voltage maximum
• Current Rating: 1 A average rectified current
• Forward Voltage Drop: 820 mV maximum at 1 A forward current
• Recovery Speed: Fast recovery characteristic with switching time ≤ 500 ns at currents > 200 mA
• Reverse Leakage: 1 µA maximum at 150 V reverse bias
• Package Type: Through-hole DO-41 (DO-204AL, Axial configuration)
• Technology: Schottky diode construction
• Compliance: ROHS3 compliant, MSL 1 classification

Parts meeting all these specifications are classified as parametric equivalents and direct substitutes. The STPS1150 base part number shares identical electrical and mechanical characteristics with the STPS1150RL, differing only in packaging configuration designation.
