Key Parameters

Substitute Part Grouping Explanation

Substitution of the FEPB16CTHE3_A/P is determined by the following critical parameters:

Configuration Match: All substitute parts maintain the 1 Pair Common Cathode diode array configuration and Surface Mount TO-263-3 (D2PAK) package format, ensuring mechanical and electrical compatibility at the board level.

Voltage Rating: Substitute parts are selected with equal or higher DC reverse voltage ratings (150 V minimum). Parts with higher voltage ratings (200 V, 170 V) provide design margin and are electrically compatible in applications requiring 150 V operation.

Current Rating: Substitute parts are selected with equal or higher average rectified current ratings (8 A minimum per diode). Parts rated for 10 A, 16 A, or 20 A provide increased current capacity while maintaining backward compatibility.

Technology Type: Both Standard and Schottky technology diodes are included as substitutes. Standard technology maintains identical electrical characteristics, while Schottky technology offers lower forward voltage drop characteristics.

Automotive Qualification: All substitute parts maintain AEC-Q101 automotive qualification and equivalent operating temperature ranges, ensuring compliance with automotive-grade requirements.

Compliance: All substitute parts are ROHS3 compliant with MSL 1 rating, matching the original part's environmental and handling specifications.

Parameter Comparison

Engineering Selection Recommendations

FEPB16DTHM3/I (Vishay General Semiconductor): This part is the manufacturer-recommended substitute from Vishay. It maintains identical Standard technology and forward voltage characteristics while providing increased voltage rating (200 V) and current capacity (16 A per diode). The part is in Active product status with higher inventory availability (921 Pcs). This substitute is recommended for applications requiring design margin or higher current capacity while maintaining the same technology platform and automotive qualification.

STTH1602CG-TR (STMicroelectronics): This Standard technology diode array provides 200 V voltage rating and 10 A current capacity. It features improved reverse recovery time (26 ns versus 35 ns) and lower reverse leakage current (6 µA @ 200 V). The part is in Active product status with substantial inventory (3630 Pcs). This substitute is suitable for applications where faster switching characteristics are beneficial. Note that automotive grade and AEC-Q101 qualification are not specified for this part.

STPS40170CGY-TR (STMicroelectronics): This Schottky technology diode array provides 170 V voltage rating and 20 A current capacity. Schottky technology delivers lower forward voltage drop (920 mV @ 20 A) compared to Standard technology, resulting in reduced power dissipation. The part is in Active product status with highest inventory availability (2230 Pcs) and maintains AEC-Q101 automotive qualification. This substitute is recommended for applications where thermal management and efficiency are critical design factors.

Frequently Asked Questions (FAQ)

Q: Can FEPB16DTHM3/I be used as a direct replacement for FEPB16CTHE3_A/P?

A: Yes. FEPB16DTHM3/I is the manufacturer-recommended substitute from Vishay. Both parts share identical diode configuration (1 Pair Common Cathode), technology (Standard), forward voltage characteristics, and package format (TO-263-3 D2PAK). The substitute provides higher voltage (200 V vs. 150 V) and current (16 A vs. 8 A) ratings, making it electrically compatible for applications designed for the original part.

Q: What is the difference between Standard and Schottky technology diodes in this comparison?

A: Standard technology diodes (FEPB16CTHE3_A/P, FEPB16DTHM3/I, STTH1602CG-TR) and Schottky technology diodes (STPS40170CGY-TR) differ in forward voltage drop and reverse recovery characteristics. Schottky diodes exhibit lower forward voltage drop, reducing power dissipation and heat generation. The STPS40170CGY-TR Schottky device shows 920 mV @ 20 A compared to 950 mV @ 8 A for Standard technology, resulting in improved efficiency in high-current applications.

Q: Are all substitute parts automotive-qualified?

A: FEPB16DTHM3/I and STPS40170CGY-TR maintain AEC-Q101 automotive qualification matching the original part. STTH1602CG-TR does not specify automotive grade or AEC-Q101 qualification in the provided data. For applications requiring automotive qualification, FEPB16DTHM3/I or STPS40170CGY-TR are the appropriate selections.

Q: Can I use a substitute part with higher voltage and current ratings in my existing design?

A: Yes. All substitute parts maintain the same diode configuration and TO-263-3 D2PAK package format. Parts with higher voltage ratings (200 V, 170 V) and current ratings (10 A, 16 A, 20 A) are electrically compatible with designs specified for 150 V and 8 A operation. Higher ratings provide design margin and do not negatively impact circuit performance.

Q: What is the significance of the Last Time Buy status for FEPB16CTHE3_A/P?

A: Last Time Buy status indicates that the manufacturer is discontinuing this part number. Existing inventory (860 Pcs) will be available for a limited time. All substitute parts listed are in Active product status with higher inventory levels, ensuring long-term availability for new designs and ongoing production requirements.

Q: How do reverse recovery time differences affect circuit performance?

A: Reverse recovery time (trr) affects switching speed and efficiency in rectifier applications. STTH1602CG-TR features 26 ns trr compared to 35 ns for the original part, enabling faster switching transitions. STPS40170CGY-TR does not specify trr but Schottky technology inherently provides faster switching characteristics than Standard technology. Faster recovery times reduce switching losses and heat generation in high-frequency applications.

Q: Are all parts RoHS3 compliant?

A: FEPB16CTHE3_A/P, STTH1602CG-TR, and STPS40170CGY-TR are confirmed ROHS3 compliant. FEPB16DTHM3/I does not specify RoHS status in the provided data. For applications requiring RoHS3 compliance verification, confirm with the manufacturer or supplier.
