| UTC 1N4148 HIGH-SPEED SWITCHING DIODE DESCRIPTION The UTC 1N4148 is designed for high-speed switching application in hybrid thick-and thin-film circuits. The devices is manufactured by the silicon epitaxial planar process and packed in plastic surface mount package. DIODE 1 2 1 2 3 3 FEATURES * Ultra-high Speed * Low Forward Voltage * Fast Reverse Recovery Time SOT-23 SOT-323 1 2 1 2 SOD-123 SOD-323 SOT-23, SOT-323: 1:NC 2:Anode 3:Cathode SOD-123, SOD-323: 1:Anode 2:Cathode *Pb-free plating product number:1N4148L ABSOLUTE MAXIMUM RATINGS (Ta=25, unless otherwise noted.) PARAMETER SYMBOL RATINGS UNIT Maximum Repetitive Reverse Voltage VRRM 100 V Average Rectified Forward Current IF (AV) 200 mA Non-repetitive Peak Forward Surge Current IFSM Pulse Width = 1.0 second 1.0 A 4.0 Pulse Width = 1.0 microsecond Power Dissipation PD 500 mW Operating Junction Temperature Tj 175 Storage Temperature Range Tstg -65 ~ +200 NOTES: (1) These ratings are based on a maximum junction temperature of 200. (2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
