• Speed Classification: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Mounting Type: Through Hole
• Package / Case: TO-220-2
• Operating Temperature - Junction: -65°C ~ 150°C (minimum)
• RoHS Status: ROHS3 Compliant

Substitution Categories:

Parametric Equivalent: FES16CT-E3/45 maintains identical electrical specifications and package configuration. This part differs only in product status (Active vs. Obsolete) and packaging format (Tube vs. unspecified).

Manufacturer Recommended Equivalent: SFAF1603GHC0G from Taiwan Semiconductor Corporation provides identical core electrical parameters with additional capacitance specification (130 pF @ 4 V, 1 MHz) and automotive qualification (AEC-Q101). Operating temperature range is -55°C ~ 150°C, which is within acceptable limits for most applications requiring the original -65°C ~ 150°C range.

Parameter Comparison

Engineering Selection Recommendations

FES16CT-E3/45 Selection Criteria:

The FES16CT-E3/45 is the direct parametric equivalent from the same manufacturer. This part is recommended for applications requiring continuity with the original Vishay product line. The part maintains Active product status, ensuring long-term availability and supply chain stability. Both parts carry identical electrical specifications and ROHS3 compliance. Selection of this substitute eliminates obsolescence risk while preserving design compatibility.

SFAF1603GHC0G Selection Criteria:

The SFAF1603GHC0G from Taiwan Semiconductor Corporation is recommended for applications requiring automotive-grade qualification and AEC-Q101 certification. This part provides identical electrical performance with the addition of specified capacitance characteristics. The operating temperature range of -55°C ~ 150°C is suitable for applications where the lower -65°C limit of the original part is not required. This substitute offers an alternative supply source and active product status. ROHS3 compliance and MSL 1 rating ensure compatibility with standard manufacturing processes.

Compatibility Considerations:

All three parts share identical core electrical parameters (150 V, 16 A, 35 ns recovery time) and Through Hole TO-220-2 package configuration. Physical footprint compatibility is maintained across all substitutes. The ITO-220AC package variant of the SFAF1603GHC0G is mechanically compatible with standard TO-220AC board layouts.

Frequently Asked Questions (FAQ)

Q: Can FES16CT-E3/45 be used as a direct replacement for FES16CTHE3/45?

A: Yes. FES16CT-E3/45 is a parametric equivalent with identical electrical specifications, reverse recovery time, forward voltage, and operating temperature range. Both parts are manufactured by Vishay and share the same TO-220-2 package configuration. The primary difference is product status (Active vs. Obsolete) and packaging format (Tube).

Q: What is the difference between TO-220AC and ITO-220AC packages?

A: Both are Through Hole TO-220-2 package variants. The ITO-220AC designation indicates an isolated or improved variant. Physical footprint compatibility is maintained for standard TO-220AC board layouts. Thermal and electrical performance remain equivalent across both package designations.

Q: Is SFAF1603GHC0G suitable for non-automotive applications?

A: Yes. SFAF1603GHC0G meets all electrical requirements for the FES16CTHE3/45 application. Automotive qualification (AEC-Q101) and Grade designation indicate enhanced reliability and process control but do not restrict use in non-automotive circuits. The part is ROHS3 compliant and suitable for general-purpose rectification applications.

Q: What is the impact of the -55°C lower operating temperature limit on SFAF1603GHC0G?

A: The SFAF1603GHC0G operating range is -55°C ~ 150°C compared to -65°C ~ 150°C for FES16CTHE3/45. This 10°C difference at the lower limit affects applications requiring operation below -55°C. For standard industrial and consumer applications operating above -55°C, this specification difference has no impact on performance or reliability.

Q: Are all three parts ROHS3 compliant?

A: Yes. FES16CTHE3/45, FES16CT-E3/45, and SFAF1603GHC0G are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts are suitable for standard PCB assembly processes without additional moisture control requirements.

Q: Which substitute part should be selected for new designs?

A: For new designs, FES16CT-E3/45 or SFAF1603GHC0G are both appropriate selections. FES16CT-E3/45 maintains continuity with the original Vishay product line. SFAF1603GHC0G provides an alternative supply source with automotive qualification. Selection depends on supply chain strategy, preferred manufacturer, and specific application requirements. Both parts provide identical electrical performance and long-term product availability.
