SM15T200A-M3/9AT Equivalent & Substitute Parts

Part Overview

The SM15T200A-M3/9AT is an active Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This unidirectional Zener diode operates in the 171V reverse standoff voltage class and is designed for general-purpose transient voltage suppression applications. The device is packaged in DO-214AB (SMC) surface mount configuration and is ROHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical characteristics and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SM15T200A-M3/9AT are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 171V
• Voltage - Breakdown (Min): 190V
• Voltage - Clamping (Max) @ Ipp: 274V
• Current - Peak Pulse (10/1000µs): 5.5A or higher
• Power - Peak Pulse: 1500W
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must maintain identical voltage ratings and clamping characteristics while supporting equivalent or superior current handling capability. All substitutes are surface mount devices in DO-214AB packaging with matching compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance with unlimited moisture sensitivity rating. The 1.5SMC200A-E3/57T from Vishay is a direct equivalent with identical electrical specifications and operating temperature range. The 1.5SMC200A from Taiwan Semiconductor Corporation provides equivalent voltage and power ratings with a marginally higher peak pulse current specification (5.7A versus 5.5A), though the operating temperature minimum is -55°C compared to -65°C for the Vishay variants.

Selection between these parts depends on supply chain availability, inventory levels, and specific application temperature requirements. All three devices are suitable for general-purpose transient voltage suppression in DO-214AB surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can the 1.5SMC200A-E3/57T be used as a direct replacement for SM15T200A-M3/9AT?

A: Yes. Both devices are manufactured by Vishay and share identical voltage ratings (171V standoff, 274V clamping), current specifications (5.5A peak pulse), and operating temperature range (-65°C to 150°C). The packaging and compliance certifications are equivalent.

Q: What is the difference between the Vishay and Taiwan Semiconductor versions?

A: The Taiwan Semiconductor 1.5SMC200A maintains the same voltage and power specifications but specifies a higher peak pulse current (5.7A) and a narrower operating temperature range (minimum -55°C instead of -65°C). Voltage clamping and package type remain identical.

Q: Are all substitute parts in the same package?

A: Yes. All three parts use DO-214AB (SMC) surface mount packaging, ensuring mechanical and footprint compatibility on PCB assemblies.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

Q: Which part should I select if my application requires operation below -55°C?

A: The SM15T200A-M3/9AT or 1.5SMC200A-E3/57T from Vishay both support operation down to -65°C. The Taiwan Semiconductor version is rated only to -55°C minimum.
