SMAJ188CA-TR Description

Short technical summary and product information.

The SMAJ188CA-TR is a bidirectional Zener TVS diode designed for general purpose circuit protection. It features a reverse standoff voltage of 188V and a clamping voltage of 388V at a peak pulse current of 6A (8/20µs waveform). The device can dissipate 400W of peak pulse power.

 

This TVS diode is housed in a surface-mount DO-214AC (SMA) package, making it suitable for automated assembly. It operates over a junction temperature range of -55°C to 150°C. The part is not intended for power line protection and is classified as a general purpose application component.

 

With its bidirectional configuration, the SMAJ188CA-TR can protect circuits from both positive and negative voltage transients. The SMA package offers a compact footprint for space-constrained designs while providing adequate heat dissipation for the rated power level.
