Zener TVSs

The SMBJ30CA is a 30V bidirectional TVS diode manufactured by Littelfuse, designed for transient voltage suppression in electronic circuits.

Specifications:

  • Voltage - Reverse Standoff (V_RWM): 30V
  • Voltage - Breakdown (V_BR): 33.3V (Min)
  • Voltage - Clamping (V_C): 48.4V at 10A
  • Peak Pulse Current (I_PP): 10A (8/20µs)
  • Power - Peak Pulse (P_PP): 600W
  • Operating Temperature Range: -55°C to +150°C
  • Package: DO-214AA (SMB)
  • Polarity: Bidirectional

Descriptions:

  • Provides ESD and surge protection for sensitive electronics.
  • Bidirectional operation allows clamping of both positive and negative transients.
  • Low clamping voltage for effective protection.
  • RoHS compliant and lead-free.

Features:

  • Fast response time (<1ns).
  • High surge capability (600W).
  • Reliable performance for overvoltage protection.
  • Compact SMB package for space-constrained applications.

This diode is commonly used in power supplies, communication systems, and automotive electronics to protect against voltage spikes and transients.
