Silicon Avalanche Diodes
600W Surface Mount Transient Voltage Suppressors
SMBJ Series
Protect sensitive electronics against voltage transients induced
by inductive load switching and lightning. Ideal for the
protection of I/O interfaces, Vcc bus and other integrated
circuits.
FEATURES
• Stand-off Voltage Range 5.0 to 170 Volts
• Uni-directional and Bi-directional
• Glass passivated junction
• Jedec package designed to meet SM assembly needs
• Low head inductance
• 100% surge tested
• UL recognised
MAXIMUM RATING
• Peak Pulse Power (Ppk) 600 Watts (10 x 1000µs)@25°C
(see diagram on page 3 for wave form)
• 1.5 watt steady state
• Response time: 1 x 10-12 secs (theoretical)
• Forward surge rating: 100A, 8.3 ms single half sine-wave
(Uni-directional only)
• Operating & storage temp.: -55°C to +150°C
MECHANICAL CHARACTERISTICS
• Case: DO-214AA moulded plastic over glass
passivated junction UL94V(O) (Thermoset) Epoxy
• Terminals: Solder plated solderable per MIL-STD-750
Method 2026
• Solderable leads: 230°C for 10 seconds.
• Marking: cathode band (positive terminal, uni-directional
devices only), device code, logo
Agency Approvals: Recognized under the Components Program
of Underwriters Laboratories.
Agency File Numbers: E128662

Note: Non ‘A’ devices have higher clamping voltage. Add suffix ‘C’ to denote bi-polar devices. VBR max not quoted.
1. For Bi-directional devices having VR of 10 volts and below, the IR limit is doubled.
2. For Uni-directional devices VF = 3.5 Volts max at IF = 50A, 300 µS square wave pulse. * Preferred voltages.
