概要
Description
The SMAJ15CA is a 15V bidirectional TVS diode designed to protect sensitive electronics from voltage transients, such as ESD, lightning, and inductive load switching. Key features:
- Bidirectional clamping: Protects against both positive and negative voltage spikes.
- Peak pulse power: 400W (8/20µs waveform).
- Breakdown voltage: ~16.7V (min).
- Low clamping voltage: Limits voltage to safe levels during surges.
- SMA (DO-214AC) package: Compact and surface-mountable.
Commonly used in power supplies, communication ports, and automotive circuits for transient suppression. It responds rapidly (picosecond range) to divert excess energy, safeguarding downstream components.
For unidirectional protection, consider the SMAJ15A variant. Always verify datasheet specifications for your application.
