SMAJ15A Description

Short technical summary and product information.

The MDD SMAJ15A is a surface mount Transient Voltage Suppressor (TVS) diode in a DO-214AC, SMA package. It is designed for unidirectional transient voltage suppression applications, offering a reverse stand-off voltage of 15.0V and a maximum clamping voltage of 24.4V.

 

This TVS diode provides 400W of peak pulse power capability at a 10/1000μs waveform. It operates within a temperature range of -65°C to +150°C. The component is suitable for general-purpose applications and is packaged in tape and reel for automated assembly.

 

Key electrical characteristics include a typical reverse leakage current of less than 1μA above 10V and a duty cycle of 0.01%. The low inductance and excellent clamping capability make it effective for protecting sensitive electronic components from voltage transients.

 

Applications include I/O interfaces, AC/DC power supplies, and low-frequency signal transmission lines such as RS232 and RS485. The device features a low profile and high temperature soldering capability.
