SMAJ40CAHE3_A/H Description

Short technical summary and product information.

The Vishay Dale SMAJ40CAHE3_A/H is a surface-mount Transient Voltage Suppressor (TVS) diode designed for protecting sensitive electronics from voltage transients. It features a 40V standby voltage and a 64.5V clamping voltage at 10/1000 μs waveform.

 

With 400W of peak pulse power dissipation, this device is suitable for applications requiring robust protection against inductive load switching and lighting surges. The diode is available in unidirectional and bidirectional configurations, with this specific model being bidirectional.

 

Packaged in the DO-214AC (SMA) case, it is ideal for automated placement on printed circuit boards. The operating temperature range is -55°C to 150°C (TJ), making it suitable for various industrial and automotive environments. Its fast response time and low incremental surge resistance ensure effective protection for ICs, MOSFETs, and signal lines.

 

This TVS diode meets MSL level 1 and is AEC-Q101 qualified, indicating its suitability for automotive applications. It is designed for use in consumer, computer, industrial, automotive, and telecommunication systems.
