Product Description
Vishay SMBJ51A-E3/52 is a 1-element uni-directional transient voltage suppressor (TVS) offering 600 W peak pulse power dissipation with a surface mount DO-214AA (SMB) package. The device provides robust protection against voltage transients induced by inductive load switching, lightning surges, and other transient events, safeguarding sensitive semiconductor components.
Featuring a single diode configuration with a minimum breakdown voltage (Vbr) of 56.7 V and a maximum reverse standoff voltage (Vwm) of 51 V, this TVS diode clamps transient voltages effectively with a clamping voltage (VC) of 82.4 V, ensuring sensitive circuits remain within safe operating voltages.
Compact dimensions (4.57 mm length, 3.94 mm width, 2.24 mm height) and a 2-pin design allow easy automated PCB assembly. The glass passivated chip junction delivers high stability and rapid response times for effective surge suppression.
The device operates reliably across a wide temperature range from -55°C to 150°C and is rated for automotive applications under the AEC-Q101 standard, ensuring durability in harsh environments.
This TVS diode is ideal for industrial, laboratory, automotive, telecommunication, and consumer electronic applications requiring transient voltage protection for integrated circuits, MOSFETs, and sensor signal lines. Its low incremental surge resistance and compliance with moisture sensitivity level 1 (MSL 1) make it suitable for modern surface mount production lines.
Compact DO-214AA surface mount package for space-saving PCB design. Robust 600 W peak pulse power handling protects against severe transient events. Fast response and low leakage current optimize circuit reliability and efficiency.
Wide operating temperature range suits various industrial and automotive environments. Glass passivated junction enhances device durability and performance. Automotive standard AEC-Q101 qualification for high reliability applications.
Ideal for protecting ICs, MOSFETs, and sensitive components. Meets moisture sensitivity level 1, enabling high-temperature soldering processes. Suitable for telecommunication, industrial automation, and consumer electronics protection.
