Z01

Technical Summary: Z01xxxA Series Thyristor

Overview

The Z01xxxA series is a family of sensitive gate thyristors designed for low-power switching applications. Housed in a TO-92 plastic package, these components offer reliable performance in a compact form factor. With a peak gate power dissipation (PGM) of 2W (for 20µs pulse width) and a maximum gate current (IGM) of 1A (for 20µs pulse width), these thyristors are optimized for applications requiring precise triggering.

Key Features

• Sensitive Gate Triggering: Low gate trigger current (IGT) ranging from 3mA to 25mA depending on variant
• High Voltage Capability: Repetitive peak off-state voltage (VDRM/VRRM) options from 400V to 800V
• Thermal Performance:
  • Junction-to-ambient thermal resistance (Rth(j-a)): 150°C/W
  • Junction-to-leads thermal resistance (Rth(j-l)): 80°C/W (DC), 60°C/W (AC)
• Robust Construction: TO-92 plastic package ensures good mechanical and electrical isolation
• Wide Operating Range: Suitable for both DC and AC applications (360° conduction angle)

Applications

The Z01xxxA series is ideal for various low-power control applications including:

• AC/DC static switches
