MAC97A6RLRPG

Triacs Overview

The MAC97A6RLRPG is a silicon bidirectional thyristor (triac) manufactured by onsemi, designed for general-purpose AC switching applications. It features a sensitive gate structure capable of triggering in all four quadrants, ensuring compatibility with various drive circuits including TTL logic and microprocessor interfaces. The device is housed in a TO-92 (TO-226) through-hole package, which facilitates automated insertion. Key electrical specifications include a rated repetitive peak off-state voltage (VDRM) of 400 V and an RMS on-state current (IT(RMS)) of 0.6 A. The component operates within a junction temperature range of -40°C to +110°C and exhibits a maximum holding current of 10 mA.

Triacs Feature Summary

• Sensitive gate design enabling reliable triggering across all four operating quadrants for versatile interface compatibility.
• Robust noise immunity characterized by a minimum commutating dv/dt rating to prevent false triggering in high-noise environments.
• High surge current capability allowing the device to withstand transient load conditions during startup or fault events.

Triacs Applications

• Solid state relays requiring compact triac solutions
• Microprocessor unit (MPU) interface circuits for AC load control
• TTL logic compatible switching stages in consumer electronics

Triacs Procurement Notes

Verify component authenticity against official onsemi datasheets due to the prevalence of counterfeit discrete semiconductors. Confirm that the marking code matches the specific MAC97A6 variant, as suffixes may indicate different packaging or lead-free status without altering electrical function. Check for end-of-life notices, as this part number has been subject to discontinuation announcements by the manufacturer. Ensure storage conditions comply with moisture sensitivity levels if the device has been exposed to humid environments prior to assembly.

Triacs Selection Notes

Select this component when a low-current, 400 V rated triac is required for sensitive gate applications. The TO-92 package is suitable for low-power designs where space constraints allow through-hole mounting. Compare the 0.6 A RMS current rating against the actual load requirements to ensure adequate thermal headroom. Consider the 400 V blocking voltage relative to the peak line voltage of the application, accounting for transients. Evaluate the need for sensitive gate triggering versus standard gate types based on the available drive current from the control circuitry.

Triacs Part Context

The MAC97A6 series belongs to onsemi's portfolio of sensitive gate triacs, widely used in legacy and cost-sensitive consumer appliances. This family shares common architectural features such as diffused and glassivated junctions for parameter uniformity. The RL suffix typically denotes tape and reel packaging, distinguishing it from bulk or tube variants like the MAC97A6G. These devices are engineered for high reliability in mass-produced electronic goods.

Triacs Replacement Considerations

Publicly confirmed substitute part numbers for the MAC97A6RLRPG were not identified in the provided documentation. Cross-referencing with similar 400 V, 0.6 A sensitive gate triacs from other manufacturers requires careful verification of gate trigger currents and holding currents to ensure functional equivalence.
