Package: SMC/DO-214AB (2-pin)

Notes

• SMCJ33(C)A is a 33V Transient Voltage Suppressor with 1500W peak pulse power rating on 10/1000 μs waveform.
• Unidirectional variant (SMCJ33A): Color band denotes cathode.
• Bidirectional variant (SMCJ33CA): No color band; device operates in both directions.
• Electrical characteristics for SMCJ33(C)A:
  • Reverse Stand-off Voltage (V_RWM): 33V
  • Breakdown Voltage (V_BR): 36.7V (min) to 40.6V (max)
  • Clamping Voltage @ I_PPM: 53.3V
  • Peak Pulse Current (I_PPM): 28.1A
  • Reverse Leakage @ V_RWM: 5 μA
• This is a two-terminal diode device in a surface-mount package; pin numbering follows standard SMC/DO-214AB convention where Pin 1 is cathode and Pin 2 is anode.

T A = 25°C unless otherwise noted

Note 1: Measured on 8.3 ms single half-sine wave or equivalent square wave; Duty cycle = 4 pulses per minute maximum.
