Zener TVSs

The SMBJ30A is a 30V bidirectional Transient Voltage Suppressor (TVS) diode manufactured by LITTELFUSE.

Specifications:

  • Voltage - Reverse Standoff (V₃₀): 30V
  • Voltage - Breakdown (VBR): 33.3V (min) to 36.8V (max)
  • Voltage - Clamping (Vc): 48.4V at 10A (Ipp)
  • Peak Pulse Current (Ipp): 10A (8/20μs)
  • Power - Peak Pulse (Pppm): 600W
  • Operating Temperature Range: -55°C to +150°C
  • Package: SMB (DO-214AA)
  • Polarity: Bidirectional
  • Mounting Type: Surface Mount

Descriptions:

The SMBJ30A is designed to protect sensitive electronics from voltage transients, including ESD, lightning, and inductive switching surges. Its bidirectional configuration clamps both positive and negative voltage spikes.

Features:

  • Low Clamping Voltage for effective transient protection
  • Fast Response Time (<1ps)
  • High Surge Capability (600W peak pulse power)
  • RoHS Compliant
  • AEC-Q101 Qualified (for automotive applications)

This diode is commonly used in power supplies, communication systems, and automotive electronics for transient suppression.

(Note: Always refer to the official LITTELFUSE datasheet for detailed specifications and application guidelines.)
