Z04E Series Triac: Technical Summary

Overview

The Z04E/F series is a high-performance triac designed for AC switching applications, offering robust thermal and electrical characteristics. These components are housed in TO-202 plastic packages, ensuring reliable operation in a variety of environments. The Z04E/F series is optimized for low gate trigger current and high surge current capability, making it suitable for both industrial and consumer applications.

Key attributes include a peak gate current (IGM) of 1.2 A (for 20 µs pulses), a peak gate power (PGM) of 3 W (for 20 µs pulses), and a maximum average gate power (PG(AV)) of 0.2 W. The series is available in multiple voltage ratings (400 V to 800 V) to accommodate diverse circuit requirements.

Features

• High Voltage Ratings: Available in repetitive peak off-state voltage (V_DRM/V_RRM) options of 400 V, 600 V, 700 V, and 800 V.
• Low Gate Trigger Current (I_GT): Maximum values range from 3 mA to 10 mA, ensuring compatibility with low-power control circuits.
• Robust Thermal Performance:
  • Junction-to-ambient thermal resistance (R_th(j-a)): 80°C/W (Z04xxxE) or 100°C/W (Z04xxxF).
  • Junction-to-case thermal resistance (R_th(j-c)): 10°C/W (DC) and 7.5°C/W (AC, 360° conduction angle at 50 Hz).
• High Surge Current Capability: Supports peak gate currents up to 1.2 A for short durations.
• Quadrant Operation: Operates in all four quadrants (I-IV) for versatile AC switching.
