Z0109MARL1G

Overview

The Z0109MARL1G is a silicon bidirectional thyristor (Triac) from the Z0109MA series, manufactured by onsemi. It features a sensitive gate design capable of triggering in all four quadrants, making it suitable for direct interfacing with microprocessor units and TTL logic circuits. The device is housed in a TO-92 (TO-226AA) package and offers a peak repetitive off-state voltage of 600 V with an RMS on-state current rating of 1.0 A. Key electrical characteristics include a maximum gate trigger current of 10 mA across all quadrants, a holding current of 10 mA, and a critical rate of rise of off-state voltage (dv/dt) of 50 V/µs at 110°C. It supports a non-repetitive surge current of 8.0 A and operates within a junction temperature range of -40°C to +125°C.

Feature Summary

• Sensitive gate triggering in all four quadrants for versatile logic interface compatibility
• Injection-molded one-piece package construction for reliability
• Improved noise immunity with high dv/dt ratings
• Glassivated junctions for parameter uniformity

Applications

• Solid state relays
• Microprocessor unit interfaces
• TTL logic circuit control
• Light industrial applications
• Consumer appliance control

Procurement Notes

Verify the specific ordering suffix 'RL' corresponds to the Radial Tape and Reel packaging configuration containing 2000 devices per reel. Confirm that the component is lead-free and RoHS compliant as indicated by the '1G' suffix in the part number. Ensure the procurement documentation matches the Z0109MA/D datasheet revision for accurate thermal and electrical specifications.

Selection Notes

Select this component when a low-cost, through-hole Triac is required for controlling AC loads up to 1 Ampere. The sensitive gate characteristic allows for direct drive from standard logic levels without additional amplification. Consider the TO-92 package constraints for thermal management and ensure the application voltage does not exceed the 600 V blocking capability. Verify that the expected di/dt requirements are met by the device's commutating rating.

Part Context

The Z0109MARL1G belongs to the Z0109MA series of sensitive gate Triacs produced by onsemi. This series is designed for general-purpose AC power control applications where cost-effectiveness and ease of automated assembly are priorities. The TO-92 package provides a compact form factor suitable for consumer electronics and light industrial equipment.

Replacement Considerations

Compatible replacements within the same series include Z0103MARL1G and Z0107MARL1G, which share similar electrical characteristics and pinouts but may differ in specific voltage or current ratings. Verify that any substitute maintains the 600 V blocking voltage and 1 A RMS current requirements.
