RSA27C2RFHT116 Equivalent & Substitute Parts

Part Overview

The RSA27C2RFHT116 is a Transient Voltage Suppressor (TVS) diode manufactured by Rohm Semiconductor in Surface Mount Device (SMD) packaging. This component functions as a clamp-type TVS diode for transient voltage suppression applications. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage ratings, clamping characteristics, and peak pulse current specifications while meeting equivalent compliance and packaging standards.

Substitute Part Grouping Explanation

Substitution of the obsolete RSA27C2RFHT116 is based on the following electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

• Transient Voltage Suppressor (TVS) diode category classification
• Surface Mount Device (SMD) packaging format
• Clamp-type voltage suppression topology
• ROHS3 compliance and EAR99 export classification
• Moisture Sensitivity Level 1 (MSL 1) rating
• HTSUS commodity code alignment (8541.10.0080)

Electrical Performance Alignment:

• Voltage clamping characteristics at peak pulse current (Ipp)
• Peak pulse current rating (10/1000µs waveform)
• Power dissipation capability during transient events
• Reverse standoff voltage and breakdown voltage specifications

The MMBZ27VCLFHT116 qualifies as a direct substitute based on matching category, packaging technology, compliance certifications, and electrical performance envelope for TVS diode applications.
