ZTE1.5 thru ZTE2.4 Voltage Stabilizers Features min. 1.083 (27.5) • Silicon Stabilizer Diodes • Monolithic integrated analog circuits designed for small power stabilizer and limitation circuits, providing low dynamic resistance and high-quality stabilization performance as well as low noise. In the reverse direction, these devices show the behavior of forward-biased silicon diodes. • The end of the ZTE device marked with the cathode ring is to be connected: ZTE1.5 and ZTE2 to the negative pole of the supply voltage; ZTE2.4 to the positive pole of the supply voltage • These diodes are also available in MiniMELF case with the type designation LL1.5 … LL 2.4. max. ∅.079 (2.0) Cathode Mark min. 1.083 (27.5) max. .150 (3.8) DO-204AH (DO-35 Glass) Mechanical Data max. ∅.020 (0.52) Case: DO-35 Glass Case Weight: approx. 0.13g Packaging codes/options: D7/10K per 13” reel (52mm tape), 20K/box D8/10K per Ammo tape, (52mm tape), 20K/box Dimensions are in inches and (millimeters) Maximum Ratings (TA = 25°C unless otherwise noted) Parameter Symbol Value Unit IF 100 mA Power dissipation at Tamb = 25°C Ptot 300(1) mW Junction temperature TJ 150 °C Storage temperature range TS – 55 to +150 °C Operating Current (see Table “Characteristics”) Inverse Current Electrical and Thermal Characteristics Parameter (TA = 25°C unless otherwise noted) Symbol Min.
