Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS2FN6-M3/I are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Voltage - DC Reverse (Vr) (Max): 60 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 600 mV @ 2 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 900 µA @ 60 V
• Capacitance @ Vr, F: 100 pF @ 4V, 1MHz
• Package / Case: DO-219AB
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Schottky
• Mounting Type: Surface Mount

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in packaging designation, supplier device package labeling, or grade classification do not affect electrical or mechanical compatibility when all core parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both the SS2FN6-M3/I and SS2FN6HM3/H are active products from Vishay General Semiconductor - Diodes Division with identical electrical and mechanical specifications. Selection between these parts is based on the following engineering criteria:

Product Status and Compliance: Both parts maintain active product status and comply with ROHS3 and REACH regulations, ensuring regulatory compliance for current and future applications.

Automotive Qualification: The SS2FN6HM3/H carries AEC-Q101 automotive qualification and is designated as an automotive-grade component. The SS2FN6-M3/I does not carry automotive qualification. Selection of the automotive-qualified variant is required for applications subject to automotive industry standards and reliability requirements.

Moisture Sensitivity Level: The SS2FN6HM3/H specifies Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating superior moisture handling characteristics compared to unspecified MSL ratings. This parameter is relevant for applications with extended storage or high-humidity environmental exposure.

Inventory and Availability: The SS2FN6HM3/H maintains significantly higher inventory levels (25,875 pcs) compared to the SS2FN6-M3/I (922 pcs), supporting supply chain continuity and procurement lead time reduction.

For non-automotive applications with standard moisture handling requirements, either part is electrically and mechanically interchangeable. For automotive applications or environments requiring enhanced moisture protection, the SS2FN6HM3/H is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are the SS2FN6-M3/I and SS2FN6HM3/H electrically identical?

A: Yes. Both parts share identical electrical specifications including reverse voltage (60V), average rectified current (2A), forward voltage (600mV @ 2A), reverse leakage current (900µA @ 60V), and capacitance (100pF @ 4V, 1MHz). Fast recovery switching characteristics are identical.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes, from a mechanical and electrical standpoint. Both parts use the DO-219AB package with surface mount configuration, identical pin assignments, and identical thermal characteristics. PCB layouts and footprints are directly compatible.

Q: What is the difference between the SS2FN6-M3/I and SS2FN6HM3/H designations?

A: The primary differences are grade classification and qualification status. The SS2FN6HM3/H is automotive-grade with AEC-Q101 qualification and specifies MSL 1 (Unlimited) moisture sensitivity. The SS2FN6-M3/I does not carry automotive qualification or specified MSL rating.

Q: Which part should be selected for automotive applications?

A: The SS2FN6HM3/H is the appropriate selection for automotive applications due to AEC-Q101 qualification and automotive-grade designation. This part meets automotive industry reliability and qualification standards.

Q: Are there any temperature operating range differences?

A: No. Both parts operate across the identical junction temperature range of -55°C to 150°C.

Q: Do both parts comply with environmental regulations?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the significance of MSL 1 (Unlimited) on the SS2FN6HM3/H?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations and does not require special moisture control during storage or handling. This is advantageous for applications with extended shelf life or high-humidity environments.

Q: Are the packaging and supplier device package designations identical?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging with DO-219AB (SMF) supplier device package designation.
