Description:
The NTE4901 is a bidirectional transient voltage suppressor diode in an axial lead type package
designed for protecting intergrated circuits, MOS, hybrids and other voltage−sensitive semiconductors
and components.
Features:
D High Surge Capability
D Very Fast Clamping Time
Absolute Maximum Ratings:
Peak Pulse Power (1ms Exponential Pulse, Initial T
Power Dissipation (T
Non−Repetitive Surge Peak Forward Current (Initial T
Operating Junction Temperature, T
Storage temperature Range, T
Lead Temperature (During Soldering, 4mm from case, 10sec max.), T
Thermal Resistance, Junction−to−Case (On Infinite Heatsink), R
Note 1. For surges higher than the maximum value, the diode will present a short−circuit anode−
Electrical Characteristics: (Note 2, Note 3)
Note 2. The NTE4901 is bidirectional device; electrical characteristics apply in both directions.
Note 3. Clamping time (0V o V
Note 4. Pulse Test: Pulse Width ≤ 50ms, Duty Cycle < 2%.
