Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FESF16DTHE3_A/P are classified based on alignment with the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 16 A or higher
• Speed classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): ≤ 35 ns
• Current - Reverse Leakage @ Vr: ≤ 10 µA @ 200 V

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole
• Package / Case: TO-220-2 Full Pack configuration
• Supplier Device Package: ITO-220AC or TO-220FPAC

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Product Status: Active

Substitute parts meeting all electrical parameters within the specified tolerances and mechanical package requirements are classified as direct equivalents. Parts with minor deviations in forward voltage or maximum junction temperature are classified as functional equivalents when all other critical parameters align.

Parameter Comparison

Engineering Selection Recommendations

FESF16DT-E3/45 (Parametric Equivalent - Vishay):

The FESF16DT-E3/45 is a parametric equivalent manufactured by Vishay General Semiconductor - Diodes Division. This part maintains identical electrical specifications to the main part: 200 V reverse voltage, 16 A average rectified current, 975 mV forward voltage at 16 A, 35 ns reverse recovery time, and 10 µA reverse leakage current. The package configuration, mounting type, and supplier device package (ITO-220AC) are identical. Both parts carry ROHS3 compliance, MSL 1 rating, and Active product status. This part is suitable for direct replacement in all applications where the FESF16DTHE3_A/P is specified. Current inventory availability is 1240 pieces.

STTH1502FP (MFR Recommended - STMicroelectronics):

The STTH1502FP is a manufacturer-recommended substitute from STMicroelectronics. This part shares the same 200 V reverse voltage rating and fast recovery speed classification. The average rectified current is rated at 15 A, which is 1 A lower than the main part. Forward voltage is specified at 1.1 V @ 15 A, compared to 975 mV @ 16 A for the main part. Reverse recovery time is 36 ns, which is 1 ns higher than the main part. The maximum junction temperature is 175°C, compared to 150°C for the main part. The package is TO-220-2 Full Pack with supplier device package TO-220FPAC. All compliance ratings (ROHS3, MSL 1) and product status (Active) align with the main part. This part is suitable for applications where the 1 A current reduction and slightly higher forward voltage are acceptable within circuit design margins. Current inventory availability is 1178 pieces.

Frequently Asked Questions (FAQ)

Q: Can FESF16DT-E3/45 be used as a direct replacement for FESF16DTHE3_A/P?

A: Yes. The FESF16DT-E3/45 is a parametric equivalent with identical electrical specifications, package configuration, and compliance ratings. Both parts are manufactured by Vishay and share the same base product number (FESF16). Direct substitution is supported in all applications.

Q: What is the difference between STTH1502FP and FESF16DTHE3_A/P?

A: The STTH1502FP differs in three parameters: average rectified current (15 A vs. 16 A), forward voltage (1.1 V @ 15 A vs. 975 mV @ 16 A), and maximum junction temperature (175°C vs. 150°C). The reverse recovery time is 36 ns versus 35 ns. All other electrical and mechanical parameters align. Substitution is suitable when the 1 A current reduction and higher forward voltage fall within circuit design tolerances.

Q: Are all substitute parts in the same package?

A: All substitute parts use through-hole mounting in TO-220-2 Full Pack configuration. The main part and FESF16DT-E3/45 use ITO-220AC supplier device package with isolated tab. The STTH1502FP uses TO-220FPAC supplier device package without isolated tab specification. Physical footprint compatibility is maintained across all parts.

Q: Do all parts meet automotive qualification requirements?

A: The main part FESF16DTHE3_A/P carries AEC-Q101 automotive qualification. The FESF16DT-E3/45 and STTH1502FP specifications provided do not explicitly list AEC-Q101 qualification status. Verification of automotive qualification requirements should be confirmed against specific application requirements.

Q: What is the reverse recovery time difference between the parts?

A: The main part and FESF16DT-E3/45 both specify 35 ns reverse recovery time. The STTH1502FP specifies 36 ns. This 1 ns difference is within typical fast recovery diode performance variation and does not affect functional equivalence in standard rectification applications.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts (FESF16DTHE3_A/P, FESF16DT-E3/45, and STTH1502FP) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts are REACH unaffected and carry EAR99 ECCN classification.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements and inventory availability. For identical specifications, FESF16DT-E3/45 is preferred as a Vishay equivalent with 1240 pieces in stock. For applications where slightly higher junction temperature capability is beneficial, STTH1502FP from STMicroelectronics is suitable with 1178 pieces in stock, provided the 1 A current reduction is acceptable.
