Substitute Part Grouping Explanation

Substitution of the FEPB16GTHE3_A/I is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 400 V
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 400 V

Allowable Variation Parameters:

• Current - Average Rectified (Io) (per Diode): Equal or greater than 8 A
• Voltage - Forward (Vf) (Max) @ If: Within acceptable circuit design margins
• Operating Temperature - Junction: Equal or greater range than -55°C to 150°C

Substitute parts must maintain identical electrical performance at the specified operating point while supporting the same package footprint and thermal characteristics.

Engineering Selection Recommendations

FEPB16GTHM3/I (Vishay General Semiconductor - Diodes Division)

This substitute is manufactured by the same supplier as the main part and maintains identical electrical specifications at the 8 A operating point. The FEPB16GTHM3/I is rated for 16 A average rectified current per diode, providing increased current capacity while maintaining all other parameters. This part is in Active product status, ensuring long-term availability. It carries AEC-Q101 automotive qualification and is suitable for applications requiring the same electrical performance with additional current margin.

STTH16R04CG-TR (STMicroelectronics)

This substitute is manufactured by STMicroelectronics and meets all mandatory equivalence criteria. The STTH16R04CG-TR maintains 400 V reverse voltage rating, 50 ns reverse recovery time, and identical package configuration. Forward voltage is specified at 1.5 V @ 8 A, compared to 1.3 V for the main part. Operating temperature range extends to 175°C maximum junction temperature, exceeding the main part specification. This part is in Active product status with high inventory availability. RoHS3 compliance and MSL 1 rating are confirmed.

Both substitutes are electrically and mechanically compatible with the FEPB16GTHE3_A/I within the specified operating parameters and package footprint.

Frequently Asked Questions (FAQ)

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

A: Yes. The FEPB16GTHM3/I is electrically and mechanically compatible. Both parts share identical voltage ratings (400 V), reverse recovery time (50 ns), reverse leakage current (10 µA @ 400 V), and package configuration (TO-263-3 D2PAK). The FEPB16GTHM3/I is rated for 16 A average rectified current per diode, compared to 8 A for the main part, providing additional current capacity without affecting circuit operation at the original 8 A specification.

Q: What is the difference in forward voltage between STTH16R04CG-TR and FEPB16GTHE3_A/I?

A: The STTH16R04CG-TR is specified at 1.5 V maximum forward voltage @ 8 A, while the FEPB16GTHE3_A/I is specified at 1.3 V maximum @ 8 A. This 0.2 V difference must be evaluated within the context of circuit design margins and thermal management requirements.

Q: Are all three parts qualified to the same automotive standards?
