SMAJ530HE3_A/H Description

Short technical summary and product information.

The Vishay Dale SMAJ530HE3_A/H is a unidirectional Transient Voltage Suppressor (TVS) diode designed for sensitive electronics protection. It features a glass passivated chip junction for excellent clamping capability and a very fast response time.

 

Key electrical specifications include a working voltage (VWM) of 477V and a breakdown voltage (VBR) ranging from 530V to 550V. The device can handle a peak pulse power (PPPM) of 300W and a peak pulse current (IFSM) of 40A. Its capacitance is 90pF at 1MHz.

 

This TVS diode is housed in a DO-214AC (SMA) surface-mount package, making it suitable for space-constrained applications. The operating temperature range is -55°C to 150°C (TJ). It is suitable for automotive applications and protects against voltage transients induced by inductive load switching and lighting.

 

The SMAJ530HE3_A/H is RoHS3 compliant and meets MSL level 1 requirements.
