NTE4975 NTE ELECTRONICS, NTE4975 Datasheet - Page 2

• Manufacturer Part Number: NTE4975
• Description: Replacement Semiconductors TRANS SUPP 150V BIDIR DIODE
• Manufacturer: NTE ELECTRONICS

Specifications of NTE4975

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

Electrical Characteristics (Cont’d):
Clamping Factor: 1.33 @ full rated power
The clamping factor is defined as: The ratio of the actual V
(Breakdown Voltage) as measured on a specific device.
Note 1. Normal selection of a zener transient over voltage suppressor is by rated stand–off voltage
