TSSE3U45 RVG Schottky Diode Equivalent & Substitute Parts

Part Overview

The TSSE3U45 RVG is an active Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the SOD-123HE package. This component operates at a maximum reverse voltage of 45 V with an average rectified current rating of 3 A, making it suitable for high-speed switching and rectification circuits requiring fast recovery characteristics. The part is ROHS3 compliant and carries unlimited moisture sensitivity level classification. Substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across alternative packaging configurations or inventory sources from the same manufacturer.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSSE3U45 RVG is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part TSSE3U45H maintains identical specifications in the following key areas:

• Reverse voltage rating: 45 V maximum
• Average rectified current: 3 A
• Forward voltage drop: 470 mV at 3 A
• Recovery speed classification: Fast Recovery ≤ 500ns, > 200mA
• Reverse leakage current: 1 mA at 45 V
• Junction temperature range: -55°C to 150°C
• Package designation: SOD-123H
• Surface mount configuration
• Schottky diode technology
• ROHS3 compliance
• MSL 1 classification

The primary distinction between the main part and its substitute lies in the packaging format: the TSSE3U45 RVG is supplied in Cut Tape (CT) configuration, while the TSSE3U45H is supplied in Tape & Reel (TR) configuration. Both originate from Taiwan Semiconductor Corporation and carry identical base product number TSSE3.

Parameter Comparison

Engineering Selection Recommendations

Both the TSSE3U45 RVG and TSSE3U45H are active products from Taiwan Semiconductor Corporation with full ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by supply chain requirements and assembly process specifications rather than electrical or thermal performance differences.

The TSSE3U45 RVG in Cut Tape packaging is appropriate for lower-volume applications, prototype development, or situations where individual component handling is required. The TSSE3U45H in Tape & Reel packaging is suitable for high-volume production environments utilizing automated pick-and-place assembly equipment.

Both parts carry identical electrical performance characteristics, mechanical compatibility with SOD-123H footprints, and regulatory compliance certifications. The choice between them does not affect circuit functionality, thermal management, or reliability when applied within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can TSSE3U45H be used as a direct replacement for TSSE3U45 RVG in circuit design?

A: Yes. Both parts are electrically and mechanically identical. The TSSE3U45H operates at the same voltage ratings (45 V maximum reverse voltage), current capacity (3 A average rectified current), forward voltage drop (470 mV at 3 A), and temperature range (-55°C to 150°C). Both use the SOD-123H package for surface mount assembly. The only difference is the supply format: Cut Tape versus Tape & Reel.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging supplies individual components on tape segments, typically used for small quantities or manual assembly. Tape & Reel packaging supplies components on continuous reels, optimized for automated assembly equipment in production environments. The physical component and its electrical characteristics remain identical.

Q: Are both parts suitable for the same PCB assembly process?

A: The TSSE3U45 RVG (Cut Tape) is suitable for manual placement or low-volume automated processes. The TSSE3U45H (Tape & Reel) is optimized for high-speed automated pick-and-place assembly. Both mount to identical SOD-123H footprints and require the same reflow soldering profile.

Q: Do these parts have the same regulatory compliance?

A: Yes. Both TSSE3U45 RVG and TSSE3U45H are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) classification. They share identical ECCN (EAR99) and HTSUS (8541.10.0080) codes.

Q: What is the reverse leakage current specification?

A: Both parts specify 1 mA maximum reverse leakage current at the maximum reverse voltage rating of 45 V. This parameter is identical across both packaging formats.

Q: Can these Schottky diodes be used in high-frequency switching applications?

A: Yes. Both parts are classified as Fast Recovery diodes with recovery time ≤ 500ns at currents greater than 200mA, making them suitable for high-frequency rectification and switching circuits within the specified voltage and current ratings.
