Z0103MUF

Overview

The Z0103MUF is a standard 1 A triac manufactured by STMicroelectronics, belonging to the Z01 series. It features a breakover voltage of 600 V and operates within a temperature range of -40 °C to +125 °C. Key electrical parameters include a maximum holding current of 10 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 7 mA. The device exhibits a low off-state leakage current of 5 µA under specified conditions. It is housed in an SMBflat-3L surface-mount package, suitable for automated assembly processes.

Feature Summary

• Passivated construction designed for high bidirectional transient and blocking voltage capability
• Logic-level gate sensitivity optimized for direct interface with microcontrollers or logic circuits
• Surface-mount SMBflat-3L package enables compact PCB layout and automated placement

Applications

• Home appliance motor control
• Fan speed controllers
• Small load industrial process control

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm the specific suffix matches the required package and tape-and-reel specifications. Request original manufacturer datasheets and compliance certificates to ensure adherence to RoHS standards and quality requirements before finalizing procurement orders.

Selection Notes

Select this component when a 600 V rated triac with 1 A RMS current handling is required for surface-mount designs. Ensure the driving circuit can supply at least 7 mA gate current to guarantee reliable triggering across the full operating temperature range. Verify that the thermal management strategy accommodates the power dissipation inherent to the SMBflat-3L package during continuous conduction.

Part Context

This part belongs to the Z01 family of standard triacs from STMicroelectronics. The family includes variants with different voltage ratings and package options, such as the Z0107MUF which shares similar characteristics but may differ in blocking voltage. These components are widely used in AC switching applications requiring robust performance in consumer electronics and industrial equipment.

Replacement Considerations

Cross-reference with NXP Semiconductors Z0103NA0 or WeEn Semiconductors equivalents for pin-compatible alternatives. Verify that substitute devices meet the same 1 A RMS current and 600 V blocking voltage requirements while maintaining compatible gate trigger characteristics for seamless integration.
