Vishay 1-Element Uni-Directional TVS Diode 400 W 2-Pin DO-214 SMAJ40A-E3/61

Vishay SMAJ40A-E3/61 is a high-performance 1-Element Uni-Directional Transient Voltage Suppressor (TVS) diode rated for 400 watts of peak pulse power dissipation and packaged in a compact 2-pin DO-214 surface-mount package. This diode is engineered to provide superior transient voltage protection for sensitive electronic components in circuits, making it ideal for a wide range of industrial and automotive applications.

The device features a minimum breakdown voltage (Vbr) of 44.4 volts and a maximum reverse stand-off voltage (Vwm) of 40 volts, effectively guarding circuits against voltage surges without compromising normal operations. Its clamping voltage (Vc) of 64.5 volts ensures that transient voltages are limited during surge events to prevent damage to downstream components.

With a peak pulse current (Ippm) capacity of 6.2 amperes and robust electrostatic discharge (ESD) protection, this TVS diode offers reliable surge handling. The diode maintains excellent performance across an operating temperature range from -55°C to 150°C, making it suitable for extreme environmental conditions frequently encountered in automotive and industrial electronics. The device is compliant with AEC-Q101 automotive reliability standards, emphasizing its suitability for automotive systems.

The SMAJ40A-E3/61 diode's compact DO-214 package dimensions (Length: 4.5 mm, Width: 2.79 mm, Height: 2.087 mm) support efficient printed circuit board space management while enabling effective heat dissipation during operation. The device exhibits a low maximum reverse leakage current of 1 microampere, contributing to minimal power loss during standby conditions.

This transient voltage suppressor is deployed across industrial, automotive, consumer electronics, and manufacturing sectors where control over electrical transient events is critical for device integrity and system uptime. Its single-element construction guarantees precise voltage suppression performance consistent with Vishay’s TRANSZORB TVS diode series reputation for reliability and robustness.
