The 1SMB18AT3 is a 600 watt peak power unidirectional Zener transient voltage suppressor from onsemi (ON Semiconductor) designed to protect voltage-sensitive electronic components from high-voltage transients. Key electrical parameters include a reverse standoff voltage of 18V, a breakdown voltage range of 20.0V to 22.1V, and a maximum clamping voltage of 29.2V at the peak pulse current. The device delivers a peak pulse power of 600W for a 1.0 ms pulse width and features an ESD rating of Class 3 (>16 kV) per the Human Body Model, with a typical response time of less than 1 ns.
The part is housed in a void-free, transfer-molded SMB (DO-214AA) plastic package with modified L-bend leads that provide increased contact area to bond pads. It supports surface mount soldering with a maximum case temperature of 260°C for 10 seconds. The unidirectional polarity is indicated by a cathode band. The 1SMB18AT3 is suited for use in communication systems, automotive electronics, power supplies, industrial controls, and other equipment requiring robust transient protection.
The reverse standoff voltage (V_RWM) is 18 V.
The peak pulse power (P_PP) is 600 W at 1.0 ms pulse width.
The maximum clamping voltage (V_C) is 29.2 V at peak pulse current.
The device is offered in a surface mount SMB (DO-214AA) package.
It is a unidirectional TVS diode, with cathode indicated by a polarity band.
The operating temperature range is -65°C to +150°C.
