Z0109MARLRPG

Overview

The Z0109MARLRPG is a sensitive gate triac from the onsemi Z0109MA series, housed in a TO-92 (TO-226AA) package. It supports a peak repetitive off-state voltage of 600 V and an on-state RMS current of 1.0 A at a case temperature of 50°C. The device features four-quadrant triggering with a maximum gate trigger current of 10 mA across all modes. It withstands a non-repetitive surge current of 8.0 A and operates within a junction temperature range of -40°C to +125°C. The component includes enhanced noise immunity with a minimum commutating dv/dt of 50 V/µs at 110°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 automated assembly compatibility

Applications

• Solid state relays
• MPU interface circuits
• TTL logic applications
• Light industrial control systems
• Consumer appliance power control

Procurement Notes

Verify the specific ordering suffix 'RLRPG' against the manufacturer's official documentation to confirm the packaging configuration. This suffix indicates a radial tape and fan fold box containing 2000 units per box. Ensure the procurement order explicitly references the full part number Z0109MARLRPG to distinguish it from bulk or alternative reel variants within the same product family.

Selection Notes

Select this component when a compact TO-92 form factor is required for low-power AC switching applications. The 600 V blocking voltage and 1 A RMS rating suit light industrial loads. Verify that the driving circuit can supply the necessary gate trigger current, as the sensitive gate requires minimal drive energy. Confirm thermal management requirements align with the specified junction-to-ambient resistance for the intended operating environment.

Part Context

This device belongs to the Z0109MA series of silicon bidirectional thyristors manufactured by onsemi. The series is engineered for cost-effective solid-state switching solutions. The TO-92 package provides a standard through-hole mounting option suitable for high-volume consumer electronics manufacturing. The product line emphasizes reliability through diffused and glassivated junctions.

Replacement Considerations

Direct replacements must match the 600 V rating, 1 A RMS current capacity, and TO-92 pinout. Verify that substitute components offer equivalent four-quadrant triggering sensitivity and comparable thermal characteristics. Cross-reference datasheets to ensure dynamic ratings such as dv/dt and di/dt meet or exceed the original specifications.
