Product Description
STMicroelectronics SMCJ33A-TR is a high-performance 1-element uni-directional Transient Voltage Suppressor (TVS) diode designed for protecting sensitive electronic circuits from voltage spikes and transient surges. It delivers a peak pulse power dissipation of 1.5 kW within a compact surface-mount DO-214 package, making it ideal for a variety of industrial and commercial applications.
This diode features a single element construction that enables effective suppression of transient voltages, preventing damage to electronic components in power lines, communication networks, and automotive electronics that do not require automotive standard compliance. The device operates reliably within a broad temperature range from -55°C to 150°C, suited for demanding environments.
The electrical characteristics provide robust protection with a minimum breakdown voltage of 36.7 volts, a maximum reverse stand-off voltage of 33 volts, and a clamping voltage of 69.7 volts. Its pulse current capability peaks at 143 amperes during surge events. The extremely low reverse leakage current of 200 nanoamperes ensures minimal impact on normal circuit operation. Physical size dimensions of 7.15 mm in length, 6.25 mm in width, and 2.45 mm in height enable space-efficient PCB layout in surface-mount assembly.
Surface mount 2-pin DO-214 package design. 1.5 kW peak pulse power dissipation rating. Uni-directional diode configuration for surge suppression. High surge current capacity of 143 A. Operating temperature range from -55°C to 150°C.
Compact size with small footprint. Extremely low reverse leakage current. Single element per chip structure.
This TVS diode is ideal for industrial, electronic component, power supply surge protection, and electronic circuit safeguarding in telecommunications, manufacturing, and electronic systems requiring reliable transient voltage protection.
