SMBJ20CA Specifications:

  • Type: Transient Voltage Suppression (TVS) Diode
  • Model: SMBJ20CA
  • Package: DO-214AA (SMB)
  • Datasheet

Electrical Specifications:

  • Breakdown Voltage (V_BR): 22.2V to 24.5V (measured at 1mA)
  • Reverse Standoff Voltage (V_R): 20V
  • Maximum Clamping Voltage (V_C): 32.4V (at I_PP = 9.2A)
  • Peak Pulse Current (I_PP): 9.2A (10/1000µs waveform)
  • Peak Pulse Power Dissipation (P_PP): 600W (10/1000µs waveform)
  • Reverse Leakage Current (I_R): 1µA (at V_R = 20V)
  • Junction Capacitance (C_J): 700pF (at 0V, 1MHz)
  • Response Time: < 1ps (from 0V to V_BR min)


  • Bidirectional Protection: Protects against positive and negative voltage transients.
  • High Power Dissipation: Capable of dissipating up to 600W of peak pulse power.
  • Low Clamping Voltage: Ensures effective suppression of transient voltage spikes.
  • Fast Response Time: Provides near-instantaneous response to voltage transients.
  • Low Leakage Current: Minimal power loss during normal operation.
  • Surface-Mount Package: Compact SMB package for easy integration into PCBs.


  • Protection of sensitive electronic equipment from voltage transients.
  • Surge protection in power supply lines.
  • Overvoltage protection in automotive and industrial applications.
  • Protection of data lines and communication equipment.

Typical Connections:

  1. Installation: Solder the SMBJ20CA across the circuit to be protected, with the anode connected to the ground and the cathode to the signal or power line.
  2. Placement: Ideally placed close to the entry point of the transient voltage to provide the best protection.
  3. Parallel Connection: For added protection, multiple TVS diodes can be connected in parallel.

Ensure to handle and install the SMBJ20CA according to the manufacturer’s guidelines to achieve optimal performance and protection.
