Product Description
Vishay SMBJ30A-E3/5B is a single-element uni-directional transient voltage suppressor (TVS) diode designed for reliable transient overvoltage protection in sensitive electronic and automotive circuits. It provides a peak pulse power dissipation of 600 W and is housed in a low profile DO-214 (SMBJ) surface mount package ideal for compact PCB layouts.
Operating within a temperature range of -55°C to 150°C, this device ensures excellent clamping performance, limiting voltage spikes to a maximum of 48.4 V under surge conditions. Its fast response time and low incremental surge resistance enable rapid and efficient suppression of transient voltage events, safeguarding downstream components.
The device is RoHS compliant and meets the stringent AEC-Q101 automotive standard, making it suitable for automotive electronics requiring rigorous reliability and quality. Its uni-directional diode configuration with a 2-pin connection simplifies integration into protection circuits.
With a minimum breakdown voltage of 33.3 V and a maximum reverse standoff voltage of 30 V, it offers effective protection against voltage transients while allowing normal operation under rated voltages. The maximum peak pulse current of 12.4 A supports protection against high surge currents typical in industrial, telecommunications, and automotive environments.
Excellent transient voltage suppression up to 600 W peak power. Compact DO-214 surface mount package for space-saving PCB design. Wide operating temperature range suitable for harsh environments. Fast response time minimizes circuit damage during voltage spikes.
Automotive-grade quality meeting AEC-Q101 standards. Uni-directional diode configuration with 2-pin mounting. Low leakage current of 1 μA maintains circuit integrity. Industrial and automotive transient voltage protection applications.
This Vishay TRANSZORB® TVS diode series is widely used in electronic equipment, power supplies, and communications systems to improve overall system robustness by efficiently diverting harmful voltage surges away from protected devices. It integrates easily into PCB layouts requiring reliable transient voltage suppression in demanding industrial or automotive environments.
