SS2PH9-M3/85A Equivalent & Substitute Parts

Part Overview

The SS2PH9-M3/85A is an active Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at 90V DC reverse voltage with a 2A average rectified current rating and is housed in a DO-220AA (SMP) package. The part is supplied in Tape & Reel (TR) packaging format.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across all critical parameters. Alternative packaging formats and supplier configurations may necessitate substitution while preserving functional performance in the target application.

Substitute Part Grouping Explanation

Substitution of the SS2PH9-M3/85A is determined by equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 90 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 800 mV @ 2 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 1 µA @ 90 V
• Capacitance @ Vr, F: 65 pF @ 4V, 1MHz

Mechanical Parameters (Must Match):

• Package / Case: DO-220AA
• Mounting Type: Surface Mount
• Technology: Schottky

Allowable Variations:

• Packaging format: Tape & Reel (TR) to Cut Tape (CT) & Digi-Reel® conversion is permitted
• Supplier inventory configuration does not affect electrical or mechanical compatibility

The substitute part SS2PH9-M3/84A maintains identical electrical and mechanical specifications while differing only in packaging delivery format.

Parameter Comparison

Engineering Selection Recommendations

Both the SS2PH9-M3/85A and SS2PH9-M3/84A are active products from Vishay General Semiconductor - Diodes Division with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than functional performance.

SS2PH9-M3/85A is supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly operations requiring continuous reel feeding.

SS2PH9-M3/84A is supplied in Cut Tape (CT) & Digi-Reel® format, suitable for applications requiring smaller quantity procurement or alternative tape handling configurations.

Both parts maintain ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity level (MSL 1). The base product number SS2PH9 is common to both variants, confirming die-level equivalence.

Frequently Asked Questions (FAQ)

Q: Are SS2PH9-M3/85A and SS2PH9-M3/84A electrically identical?

A: Yes. Both parts are Schottky rectifier diodes with identical electrical specifications: 90V reverse voltage, 2A average rectified current, 800mV forward voltage at 2A, fast recovery characteristics, and identical junction temperature range (-55°C to 175°C).

Q: What is the difference between these two part numbers?
