Equivalent & Substitute Parts Reference – SS56-HF

Part Overview

SS56-HF is a surface mount Schottky rectifier diode with a maximum reverse voltage of 60 V and an average rectified current of 5A, packaged in DO-214AC (SMA) form factor. The product is active and has RoHS3 compliance with unlimited moisture sensitivity level (MSL 1). Identifying equivalent or substitute diodes is necessary to ensure continuity in design, inventory flexibility, and multi-sourcing applications where identical electrical and mechanical characteristics are required.

Substitute Part Grouping Explanation

All substitute and equivalent part grouping is determined strictly by matching technology type (Schottky), maximum reverse voltage (60 V), average rectified current (5A), maximum forward voltage at rated current (700 mV @ 5A), leakage current, capacitance, recovery speed, mounting type (surface mount), package/case (DO-214AC, SMA), operating temperature range (-55°C ~ 150°C), RoHS compliance, and MSL. Only those parts matching all key parameters are grouped as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection among SS56-HF and SS56 must be made based on part status (active), RoHS compliance, and unlimited moisture sensitivity level (MSL 1). Both parts are active, surface mount Schottky diodes with identical critical electrical and mechanical parameters per the provided data. RoHS status is compliant for both, supporting environmentally regulated applications.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for Schottky diode substitution?
A: All key parameters including technology, maximum reverse voltage, average rectified current, maximum forward voltage at the rated current, reverse leakage, recovery speed, and capacitance must be identical.

Q: Is the package type interchangeable between SS56-HF and SS56?
A: Both use the DO-214AC (SMA) surface mount package; these are mechanically compatible.

Q: Are there differences in environmental compliance between these parts?
A: Both are specified as RoHS compliant and rated with unlimited moisture sensitivity level (MSL 1).

Q: Can the SS56-HF be replaced with SS56 in designs requiring fast recovery time and surface mounting?
A: Yes, both diodes have fast recovery speed (≤500ns, >200mA) and identical surface mount packaging.

Q: Is there any variance in reverse leakage?
A: The reverse leakage differs: SS56-HF specifies 1 mA @ 60 V; SS56 specifies 500 µA @ 60 V. Compatibility must follow strict project requirements.
