The SMAJ54A is a unidirectional Zener TVS diode from Bourns, part of the SMAJ series. It is designed to protect sensitive electronic circuits from voltage transients and surges. Key electrical specifications include a reverse standoff voltage (VRWM) of 54 V, a maximum clamping voltage of 87.1 V at peak pulse current, and a peak pulse power dissipation of 400 W (10/1000 μs waveform). The device can handle a peak pulse current of 4.6 A and a forward surge current of 40 A (8.3 ms).
This TVS diode is suitable for general purpose applications requiring transient voltage protection. It features a fast response time typical of Zener TVS diodes. The device operates over a junction temperature range of -55°C to 150°C and has a steady state power dissipation of 1.0 W at 75°C lead temperature.
The SMAJ54A is offered in a compact DO-214AC (SMA) surface mount package, which is compatible with standard pick-and-place assembly processes. The package is RoHS3 compliant and has a moisture sensitivity level (MSL) of Level 1 (unlimited).
