Z0109MARLRFG

Overview

The Z0109MARLRFG is a sensitive gate triac from the Z0109MA series, manufactured by onsemi. It is housed in a TO-92 (TO-226AA) package and designed for solid state relays, MPU interfaces, and TTL logic applications. The device features a peak repetitive off-state voltage of 600 V and an on-state RMS current rating of 1.0 A at a case temperature of 50°C. It supports four-quadrant triggering with a maximum gate trigger current of 10 mA across all modes. The component includes a high surge current capability of 8.0 A and operates within a junction temperature range of -40°C to +125°C.

Feature Summary

• Sensitive gate design enabling direct interfacing with logic level ICs and microprocessors
• Four-quadrant triggering capability for versatile circuit integration
• Injection-molded package construction for reliability and automated assembly compatibility

Applications

• Solid state relays
• Microprocessor unit interface circuits
• TTL logic control systems

Procurement Notes

Verify the specific ordering suffix 'RLRFG' against the manufacturer's official documentation to confirm packaging details. This suffix indicates a radial tape and fan fold box configuration containing 2000 units per box. Ensure the selected variant matches the required lead orientation and adhesive tape visibility specifications for your automated insertion equipment.

Selection Notes

Select this component when a compact TO-92 package is required for low-power AC switching applications. The sensitive gate characteristic allows for lower drive currents compared to standard triacs, making it suitable for direct connection to digital logic outputs without additional amplification stages.

Part Context

This part belongs to the Z0109MA series of silicon bidirectional thyristors. The series is characterized by planar passivation and glassivated junctions to ensure parameter uniformity and noise immunity. The device is Pb-free and complies with environmental standards for electronic components.

Replacement Considerations

Direct replacements must match the 600V blocking voltage, 1A RMS current rating, and TO-92 package outline. Verify that alternative manufacturers offer compatible four-quadrant sensitive gate characteristics and similar thermal resistance values.
