MAC97A8

Triacs Overview

The MAC97A8 is a planar passivated, very sensitive gate four-quadrant triac manufactured by onsemi. It is housed in a TO-92 (TO-226) through-hole package designed for direct interfacing with microcontrollers and logic integrated circuits. The device features a rated repetitive off-state voltage of 600 V and an RMS on-state current of 0.6 A. Key electrical parameters include a non-repetitive peak on-state current of 8 A, a maximum holding current of 10 mA, and a gate trigger voltage of 2.5 V. It operates within a temperature range of -40°C to +110°C.

Triacs Feature Summary

• Very sensitive gate architecture enabling direct interface with low-power logic circuits
• Planar passivated construction for enhanced reliability
• Four-quadrant triggering capability for universal AC load control

Triacs Applications

• General-purpose bidirectional switching
• Phase control applications such as light dimmers
• Solid-state relays

Triacs Procurement Notes

Verify component authenticity against the manufacturer's official documentation. Confirm that the specific ordering suffix matches the required packaging configuration. Check for end-of-life status or obsolescence notices prior to finalizing procurement plans to ensure long-term supply chain stability.

Triacs Selection Notes

Select this component when a compact TO-92 package is required for low-current AC switching. Ensure the gate drive circuit can provide at least 5 mA to guarantee reliable triggering across all four quadrants. Verify that the 600 V blocking voltage meets the peak line voltage requirements of the target application.

Triacs Part Context

This part belongs to the MAC97A series of logic-level sensitive triacs from onsemi. It shares the same physical footprint and general functionality as variants like the MAC97A6 but offers higher voltage ratings. The series is widely used in consumer electronics where space constraints and cost-effectiveness are critical design factors.

Triacs Replacement Considerations

Direct substitutes include the MAC97A8G (RoHS compliant version) and the MAC97A8RL1G. Cross-manufacturer equivalents such as the WeEn Semiconductors MAC97A8,116 may be considered if pinout compatibility and electrical specifications align.
