MAC15SD TRIAC Equivalent & Substitute Parts

Part Overview

The MAC15SD is a logic-sensitive gate TRIAC manufactured by onsemi, rated for 400 V off-state voltage and 15 A on-state current in a TO-220 through-hole package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The MAC15SD serves as a general-purpose AC switching device for applications requiring sensitive gate triggering characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAC15SD is determined by the following critical parameters:

• Triac Type: Logic - Sensitive Gate configuration
• Voltage - Off State: Minimum 400 V (higher ratings acceptable for derating applications)
• Current - On State (It (RMS)): Minimum 15 A (higher ratings acceptable)
• Voltage - Gate Trigger (Vgt): Maximum 1.5 V (ensures gate sensitivity compatibility)
• Current - Gate Trigger (Igt): Maximum 5 mA (gate drive circuit compatibility)
• Current - Hold (Ih): Maximum 10 mA (holding current requirement)
• Package / Case: TO-220-3 (mechanical and thermal interface requirement)
• Mounting Type: Through Hole (PCB assembly compatibility)

The BTA216-600D,127 qualifies as a substitute because it meets or exceeds all critical parameters while maintaining the same package and mounting configuration. The higher voltage rating (600 V vs. 400 V) and increased current capacity (16 A vs. 15 A) provide design margin without compromising gate sensitivity or hold current specifications.

Engineering Selection Recommendations

The BTA216-600D,127 is the qualified substitute for the MAC15SD based on the following criteria:

• All critical electrical parameters meet or exceed MAC15SD specifications
• Active product status ensures long-term availability and supply chain continuity
• RoHS compliance of the BTA216-600D,127 supports modern manufacturing and environmental standards
• Identical package and mounting configuration (TO-220-3, through-hole) ensures direct PCB compatibility without layout modifications
• Extended operating temperature range (125°C vs. 110°C) provides additional thermal margin
• Higher surge current rating (140-150 A vs. 120 A) improves transient performance

Frequently Asked Questions (FAQ)

Q: Can the BTA216-600D,127 be used as a direct replacement for the MAC15SD?

A: Yes. The BTA216-600D,127 meets all critical electrical and mechanical parameters required for MAC15SD substitution. The TO-220-3 package and through-hole mounting are identical, requiring no PCB modifications.

Q: What is the significance of the higher voltage rating (600 V vs. 400 V) on the BTA216-600D,127?

A: The higher off-state voltage rating provides design margin and allows operation in higher voltage applications. For circuits designed for 400 V operation, the BTA216-600D,127 will function identically while offering improved voltage headroom.

Q: Are the gate trigger characteristics identical between these parts?

A: Yes. Both parts specify a maximum gate trigger voltage (Vgt) of 1.5 V and maximum gate trigger current (Igt) of 5 mA, ensuring compatible gate drive circuit requirements.

Q: Does the RoHS compliance difference affect substitution?

A: The BTA216-600D,127 is RoHS compliant, which is advantageous for new designs and manufacturing processes subject to environmental regulations. The MAC15SD is RoHS non-compliant, making the substitute preferable for modern applications.

Q: What is the impact of the higher hold current (15 mA vs. 10 mA) on the BTA216-600D,127?

A: The higher hold current specification on the BTA216-600D,127 is within acceptable margins for most applications. Circuits designed for the MAC15SD's 10 mA hold current will operate reliably with the substitute's 15 mA specification.

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

A: The BTA216-600D,127 supports operation to 125°C junction temperature compared to the MAC15SD's 110°C maximum. This extended range provides additional thermal margin in high-temperature environments.
