Z0103MARLRFG

Overview

The Z0103MARLRFG is a silicon bidirectional thyristor (Triac) from the Sensitive Gate Triacs Series by onsemi. It 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. The device supports a peak non-repetitive surge current of 8.0 A and operates within a junction temperature range of -40 to +125°C. Packaged in a TO-92 (TO-226AA) plastic housing, this specific suffix denotes a radial tape and fan fold box configuration containing 2000 units per box. The component utilizes injection-molded construction with diffused and glassivated junctions for parameter uniformity.

Feature Summary

• Sensitive gate triggering capability across all four quadrants for compatibility with logic-level ICs and low-power drivers
• Injection-molded one-piece package designed for automatic insertion equipment
• Improved noise immunity with a minimum critical rate of rise of off-state voltage of 10 V/µs at 110°C

Applications

• Solid state relays
• MPU interface circuits
• TTL logic interfacing
• Light industrial control applications
• Consumer appliance switching

Procurement Notes

Verify the ordering suffix 'RFG' corresponds to the Radial Tape and Fan Fold Box packaging format with 2000 units per box. Confirm that the round side of the TO-92 package and adhesive tape are visible on the reverse side as specified in the shipping information. Ensure the procurement request explicitly cites the full part number Z0103MARLRFG to distinguish it from bulk or standard reel variants.

Selection Notes

Select this component when a 600 V blocking voltage and 1 A RMS current capacity are required for AC load switching. The sensitive gate characteristic allows direct interfacing with microprocessors and TTL logic without additional drive circuitry. Verify that the application environment remains within the specified -40 to +125°C junction temperature range and that the thermal resistance characteristics align with the system's heat dissipation capabilities.

Part Context

This device belongs to the Z0103MA series of sensitive gate triacs manufactured by onsemi. The series is engineered for cost-effective integration into consumer and light industrial electronics. The TO-92 package provides a compact form factor suitable for high-volume automated assembly processes while maintaining robust electrical performance for general-purpose AC power control tasks.

Replacement Considerations

Cross-reference with other Z0103MA series variants such as Z0103MARL1G or Z0103MAG if different packaging formats are required. Ensure substitute parts maintain the same 600 V rating, 1 A current handling, and sensitive gate specifications to guarantee functional equivalence in existing circuit designs.
