SMF60AT1G Equivalent & Substitute Parts

Part Overview

The SMF60AT1G is a 60V Transient Voltage Suppressor (TVS) diode manufactured by onsemi, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 96.8V maximum clamping voltage, 1.8A peak pulse current capability, and 200W peak pulse power rating in a compact SOD-123FL package.

The SMF60AT1G is classified as obsolete. Equivalent substitute parts are available from active manufacturers, providing identical electrical performance and mechanical compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMF60AT1G are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff: 60V (exact match required)
• Voltage - Breakdown (Min): 66.7V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 96.8V (exact match required)
• Current - Peak Pulse (10/1000µs): 1.8A (exact match required)
• Power - Peak Pulse: 200W (exact match required)
• Package / Case: SOD-123F (mechanical compatibility required)
• Mounting Type: Surface Mount (assembly compatibility required)
• Type: Zener, Unidirectional Channels: 1 (functional equivalence required)

All substitute parts listed maintain identical electrical specifications and package compatibility with the original SMF60AT1G component.

Parameter Comparison

Engineering Selection Recommendations

Both SMF60A-T13 (Littelfuse Inc.) and SMF60A-TP (Micro Commercial Co) are direct electrical and mechanical equivalents to the obsolete SMF60AT1G. Selection between these active alternatives is based on the following factors:

SMF60A-T13 (Littelfuse Inc.): Active product status with ROHS3 compliance. Operating temperature range matches the original specification (-55°C ~ 150°C TJ). Suitable for applications requiring exact thermal performance alignment with the SMF60AT1G.

SMF60A-TP (Micro Commercial Co): Active product status with ROHS3 compliance. Extended operating temperature range (-65°C ~ 175°C TA) provides broader thermal margin. Suitable for applications requiring enhanced temperature performance or operating in extended environmental conditions.

Both parts are available in Tape & Reel packaging for production assembly. Selection should be based on supply chain availability, lead time requirements, and thermal performance needs of the target application.

Frequently Asked Questions (FAQ)

Q: Can SMF60A-T13 or SMF60A-TP be used as direct replacements for SMF60AT1G?

A: Yes. Both parts are electrically and mechanically equivalent. All critical parameters—reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and power rating—are identical. Package and mounting type are identical (SOD-123F, surface mount).

Q: What is the difference between SMF60A-T13 and SMF60A-TP?

A: The primary difference is the operating temperature range. SMF60A-T13 operates from -55°C to 150°C (TJ), matching the original SMF60AT1G specification. SMF60A-TP operates from -65°C to 175°C (TA), providing extended thermal performance. Both maintain identical electrical specifications.

Q: Are there packaging differences between these parts?

A: SMF60AT1G was supplied in SOD-123FL packaging. Both substitute parts (SMF60A-T13 and SMF60A-TP) use SOD-123F packaging. These are mechanically compatible for surface-mount assembly. SMF60A-T13 is available in Tape & Reel format; SMF60A-TP is also available in Tape & Reel format.

Q: Do the substitute parts meet RoHS compliance?

A: Yes. Both SMF60A-T13 and SMF60A-TP are ROHS3 compliant. The original SMF60AT1G RoHS status was not specified in available documentation.

Q: Which substitute part should I select for a new design?

A: Selection depends on application thermal requirements. For standard operating conditions matching the original specification, either part is suitable. For applications requiring extended temperature performance, SMF60A-TP is recommended due to its wider operating range.
