SYMBOLS AND DEFINITIONS VWM Standoff Voltage: Applied Reverse Voltage to assure a nonconductive condition V(BR) Breakdown Voltage: This is the Breakdown Voltage the device will exhibit at 25°C VC Maximum Clamping Voltage: The maximum peak voltage appearing across the TVS when subjected to the peak pulse current in a one millisecond time interval. The peak pulse voltage is the combination of voltage rise due to both the series resistance and thermal rise and positive temperature coefficient (αV(BR)) IPP Peak Pulse Current: The peak current during the impulse PPP Peak Pulse Power: The pulse power as determined by the product of VC and IPP ID Standby Current: The current at the standoff voltage (VWM) I(BR) Breakdown Current: The current used for measuring breakdown voltage (V(BR)) Rev. 20160527 High-reliability discrete products and engineering services since 1977 1N5555-1N5558 Transient Voltage Suppressor 1500 Watt MECHANICAL CHARACTERISTICS Case DO-13 Marking Alpha-numeric, body painted Polarity Cathode band Rev. 20160527 High-reliability discrete products and engineering services since 1977 1N5555-1N5558 Transient Voltage Suppressor 1500 Watt Rev. 20160527
