1. Product Description:

️· Type: Zener Diodes (ZPY10 to ZPY200 series)
️· Package: Plastic case (UL94V-0 rated - a flame retardant standard)
️· Standard Tolerance: Most have a standard tolerance of approximately ±5% (international E24 standard). The ZPY10 to ZPY200 series have a tighter, 2% tolerance, which makes them a "specially selected" variant.

2. Electrical Characteristics (Max Ratings & Typical Values):

️· Repetitive Power Dissipation (Ptot): 1.3W at T_A = 50°C.
️· Non-Repetitive Peak Power Dissipation (Pzsm): 40W at T_A = 25°C
️· Junction Temperature (Tj): -50°C to +150°C
️· Storage Temperature (Ts): -50°C to +175°C
️· Thermal Resistance (RthA): < 45 K/W (junction to ambient air)
️· Thermal Resistance (RthT): < 15 K/W (junction to terminal)
️· Zener Voltage: Detailed in the table below.
️· Test Current (Iz): Varies by device (typically 5mA or 25mA).
️· Dynamic Resistance (r_zj): Varies by device.
️· Temperature Coefficient of Zener Voltage (α_vz): Varies by device (in units of 10^-4/°C).
️· Reverse Voltage (Vr): The maximum reverse voltage the diode can withstand.
️· Maximum Zener Current (Izmax): The maximum current that can be safely passed through the Zener diode.

Important Notes from the Text:

️· "Specially Selected": The ZPY10 to ZPY200 series represent a selection process for tighter tolerances.
️· Values on Request: Other voltage tolerances and Zener voltages can be obtained by request.
️· Ambience Temperature: The datasheet makes repeated mentions of ambience temperature as a factor to consider.
