Transient Suppression Diodes For General Purpose Use GENERAL DESCRIPTION The SMAJ, SMBJ, and SMCJ Series are a poplar format of general purpose transient voltage suppression diodes. They are based on the low leakage, high reliability, but low cost glass passivated chip rectifier technology. FEATURES APPLICATIONS SMAJ Glass passivated chip Consumer 400W , 600W and 1500W types (10/1000us) Industrial Low leakage Telecom SMBJ Flat clamping Computer V ery fast response time Halogen Free 1A leakage for 12V and up SMCJ Lead-Free Terminations HOW TO ORDER SMAJ 12 C A Series Voltage Polarity Tolerance WM SMAJ = 400W 5V - 400V C = Bi-directional A = 5% Volage SMBJ = 600W = Uni-directional Tolerance SMCJ = 1500W MAXIMUM RATINGS RATING SYMBOL SMAJ SMBJ SMCJ UNITS 1 Peak power dissipation with a 10/1000us waveform P 400 600 1500 Watts PPM 1 Peak pulse current with a 10/1000us waveform I See tables Amps PPM Power dissipation on infinite heat sink at TL = 75C P 1.0 5.0 6.5 Watts D Peak forward surge current,8.3ms single half I 40 100 200 Amps FSM 2 sine-wave unidirectional only Operating junction and storage temperature range T ,T -55 ~ 150 -55 ~ 150 -55 ~ 150 C J STG Typical thermal resistance junction to air 120 100 75 C/W JA Typical thermal resistance junction to case 30 20 15 C/W JC NOTES: 1.
