MAC97A8,412

Triacs Overview

The MAC97A8,412 is a planar passivated four-quadrant triac manufactured by WeEn Semiconductors in a TO-92 (SOT54) through-hole package. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 600 mA. The device supports a non-repetitive peak on-state current (ITSM) of 8.8 A with a maximum holding current of 10 mA. Key electrical parameters include a gate trigger voltage (VGT) of 900 mV, a gate trigger current (IGT) of 4 mA, and an on-state voltage of 1.4 V. The component operates at a maximum junction temperature of +125 °C and exhibits a low leakage current of 3 µA under rated voltage conditions.

Triacs Feature Summary

• Four-quadrant sensitivity enabling direct interfacing with microcontrollers and logic integrated circuits.
• Planar passivated construction designed for industrial qualification and robust performance.
• Low gate trigger requirements suitable for low power gate trigger circuits.

Triacs Applications

• Lighting control systems
• Motor speed control applications
• Heating control circuits

Triacs Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration. The MAC97A8,412 designation corresponds to bulk pack straight leads in a TO-92 package. Confirm RoHS compliance status and lead-free plating details against the latest manufacturer documentation prior to procurement to ensure alignment with assembly requirements.

Triacs Selection Notes

Select this component when a 600 V blocking capability and 0.6 A continuous current rating are required in a compact TO-92 form factor. Ensure the application circuit accounts for the 10 mA holding current threshold to maintain conduction. Verify that the dV/dt rating of 30 V/µs is sufficient for the specific noise environment of the target design.

Triacs Part Context

This part belongs to the MAC97A8 family of very sensitive gate triacs. The MAC97A8,412 variant specifically denotes the bulk-packaged version, distinct from tape-and-reel variants such as the MAC97A8,116. Both share identical electrical characteristics but differ in manufacturing logistics and handling procedures.

Triacs Replacement Considerations

The MAC97A8G from ON Semiconductor offers similar electrical specifications but may exhibit differences in gate trigger voltage and maximum operating temperature. Verify pinout compatibility and thermal management requirements before substituting.
