Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FEPB16GTHE3_A/P is determined by the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 400 V minimum
• Current - Average Rectified (Io) (per Diode): 8 A minimum
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Acceptable Parameter Variations:

• Voltage - Forward (Vf) (Max) @ If: Equivalent or lower values acceptable
• Reverse Recovery Time (trr): Equivalent or lower values acceptable
• Current - Reverse Leakage @ Vr: Equivalent or lower values acceptable
• Operating Temperature - Junction: Extended ranges acceptable

Substitute parts must maintain electrical equivalence within the specified application envelope and preserve mechanical compatibility with existing PCB layouts and thermal management designs.

Engineering Selection Recommendations

FEPB16GTHM3/I (Vishay General Semiconductor - Diodes Division)

This substitute is a direct manufacturer recommendation from Vishay. The FEPB16GTHM3/I maintains identical electrical characteristics to the main part across all critical parameters: 400 V reverse voltage, 50 ns reverse recovery time, and 10 µA reverse leakage current. The device features an increased current rating of 16 A per diode, providing enhanced thermal margin and current capacity. Product status is Active, ensuring long-term availability. This part is suitable for direct replacement in applications where the increased current capability does not create thermal or design constraint conflicts.

STTH16R04CG-TR (STMicroelectronics)

This substitute provides electrical equivalence at the 8 A current rating with identical reverse voltage (400 V) and reverse recovery time (50 ns) specifications. The forward voltage is specified at 1.5 V @ 8 A, representing a 0.2 V increase compared to the main part. Operating temperature range extends to 175°C maximum junction temperature, exceeding the main part specification. Product status is Active with high inventory availability (21,935 pcs). This part is suitable for applications where the slightly elevated forward voltage is within system design margins and where extended high-temperature operation is beneficial.

Both substitute parts maintain the TO-263-3 D2PAK package configuration, ensuring mechanical and thermal interface compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can FEPB16GTHM3/I be used as a direct replacement for FEPB16GTHE3_A/P?

A: Yes. The FEPB16GTHM3/I is a manufacturer-recommended substitute with identical reverse voltage (400 V), reverse recovery time (50 ns), and reverse leakage current (10 µA) specifications. The increased current rating (16 A vs. 8 A) provides additional thermal margin. Both devices use the TO-263-3 D2PAK package and are configured as 1 Pair Common Cathode diode arrays.

Q: What is the difference in forward voltage between the main part and STTH16R04CG-TR?

A: The STTH16R04CG-TR specifies a maximum forward voltage of 1.5 V @ 8 A, compared to 1.3 V @ 8 A for the FEPB16GTHE3_A/P. This 0.2 V difference must be evaluated within the context of the application's power dissipation budget and voltage regulation requirements.

Q: Are both substitute parts available in the same packaging format?

A: Yes. Both FEPB16GTHM3/I and STTH16R04CG-TR are packaged in TO-263-3 D2PAK (2 Leads + Tab) surface mount configuration, identical to the main part. This ensures compatibility with existing PCB layouts and thermal management designs.

Q: What is the product status of each substitute part?

A: FEPB16GTHM3/I is Active status, ensuring continued manufacturing and availability. STTH16R04CG-TR is also Active status with significantly higher inventory levels (21,935 pcs). The main part FEPB16GTHE3_A/P is Last Time Buy, indicating discontinued production.

Q: Do the substitute parts meet automotive qualification requirements?

A: FEPB16GTHM3/I carries Automotive grade designation and AEC-Q101 qualification, matching the main part. STTH16R04CG-TR qualification status is not specified in the provided parameters.

Q: Can FEPB16GTHM3/I handle higher current applications than the original part?

A: FEPB16GTHM3/I is rated for 16 A average rectified current per diode, compared to 8 A for the main part. This increased rating provides additional design margin but does not change the fundamental electrical characteristics required for substitution. Application suitability depends on thermal management design and system current requirements.

Q: What is the operating temperature range difference between the main part and STTH16R04CG-TR?

A: The main part operates from -55°C to 150°C junction temperature. STTH16R04CG-TR extends the maximum operating temperature to 175°C, providing 25°C additional high-temperature margin. The minimum operating temperature for STTH16R04CG-TR is -40°C, which is 15°C higher than the main part.
