HFA16TA60CS Equivalent & Substitute Parts

Part Overview

The HFA16TA60CS is a general-purpose diode array manufactured by Vishay General Semiconductor - Diodes Division, configured as a 1 Pair Common Cathode with 600V reverse voltage rating and 8A average rectified current per diode. The device is housed in a TO-263-3 D2PAK surface mount package and features fast recovery characteristics with a 55 ns reverse recovery time.

This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support, maintenance, and new production applications. The HFA16TA60CS is part of the HEXFRED® series and carries RoHS non-compliant status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HFA16TA60CS is determined by the following critical parameters that must remain constant or be exceeded:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• Voltage - DC Reverse (Vr) (Max): 600 V (minimum requirement)
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 55 ns (maximum)

Parameters Allowed to Exceed Original Specifications:

• Current - Average Rectified (Io) (per Diode): May be equal to or greater than 8A
• Voltage - Forward (Vf) (Max) @ If: May be equal to or less than 1.7 V @ 8 A
• Current - Reverse Leakage @ Vr: May be equal to or less than 5 µA @ 600 V
• Operating Temperature - Junction (Max): May be equal to or greater than 150°C

The STTH16L06CG-TR from STMicroelectronics qualifies as a substitute based on these criteria, offering improved current rating (10A versus 8A) and higher maximum junction temperature (175°C versus 150°C) while maintaining all mandatory electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

HFA16TA60CS (Vishay): The original part is classified as obsolete and carries RoHS non-compliant status. This part should be used only in legacy applications where existing inventory is available and regulatory compliance is not a requirement. New designs should not incorporate this component.

STTH16L06CG-TR (STMicroelectronics): This substitute part is classified as active and carries ROHS3 compliance certification, making it suitable for new designs and applications requiring regulatory adherence. The STTH16L06CG-TR provides superior electrical performance with a 25% increase in current rating (10A versus 8A) and extended maximum junction temperature capability (175°C versus 150°C). The package, mounting type, and critical electrical parameters (voltage rating, recovery time) are identical to the original part. This substitute is recommended for all new applications and as a replacement for obsolete inventory.

Frequently Asked Questions (FAQ)

Q: Can the STTH16L06CG-TR directly replace the HFA16TA60CS in existing PCB designs?

A: Yes. Both parts use identical TO-263-3 D2PAK surface mount packages with the same pinout and lead configuration. No PCB modifications are required for physical substitution.

Q: What are the key electrical differences between these parts?

A: The STTH16L06CG-TR provides higher current capacity (10A versus 8A per diode) and extended maximum junction temperature (175°C versus 150°C). Forward voltage at 8A is slightly higher (1.8V versus 1.7V), and reverse leakage current is slightly higher (8µA versus 5µA at 600V). Both parts maintain identical 600V reverse voltage rating and 55ns reverse recovery time.

Q: Is the STTH16L06CG-TR suitable for applications originally designed for the HFA16TA60CS?

A: Yes. The substitute part meets or exceeds all mandatory electrical and mechanical parameters. The higher current rating and temperature capability provide additional design margin. Applications operating at or below the original 8A specification will function identically or with improved performance.

Q: What is the significance of the RoHS compliance difference?

A: The HFA16TA60CS is RoHS non-compliant, while the STTH16L06CG-TR is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the STTH16L06CG-TR is the only acceptable option. For legacy or non-regulated applications, either part may be used based on availability.

Q: Are there any thermal considerations when substituting these parts?

A: The STTH16L06CG-TR supports a higher maximum junction temperature (175°C versus 150°C). This provides additional thermal margin in applications operating near temperature limits. No thermal design changes are required for substitution.

Q: What packaging formats are available for the STTH16L06CG-TR?

A: The STTH16L06CG-TR is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, with 20,320 pieces currently in stock.
