Product Description
STMicroelectronics SM30T39AY is a 1-element uni-directional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage transients resulting from inductive load switching and lightning strikes. This diode has a peak pulse power dissipation capacity of 3 kW and is housed in a compact DO-214 surface-mounted package with two pins, making it ideal for tight PCB layouts.
It features a minimum breakdown voltage of 36.7 V and a maximum reverse standoff voltage of 33 V, ensuring that the diode remains inactive during normal circuit operation but clamps overvoltages effectively. Its clamping voltage is 58 V, which limits the voltage spike to safe levels for downstream components.
Designed for harsh environments, the SM30T39AY operates reliably over a wide temperature range from -55°C to 150°C and meets the automotive grade AEC-Q101 standard, making it suitable for automotive and industrial applications. The maximum peak pulse current rating of 490 A allows it to withstand high energy surges, while the low reverse leakage current of 200 nA contributes to energy efficient circuit design.
This TVS diode is primarily used in power and signal line protection in telecommunications, automotive electronics, industrial control systems, and consumer electronics to prevent damage from transient voltage events. Its surface mount form factor DO-214 package offers ease of assembly and reliable soldering performance.
This diode provides uni-directional transient voltage protection for sensitive electronics. Capable of dissipating peak pulse power of 3 kW for surge robustness. Compact 2-pin DO-214 surface mount package for space-saving PCB design.
Wide operating temperature range from -55°C to 150°C ensures durability. Minimum breakdown voltage: 36.7 V, designed to clamp surges effectively. Maximum reverse standoff voltage of 33 V keeps normal operation safe. Maximum peak pulse current of 490 A supports high surge currents in circuits.
Automotive standard AEC-Q101 certification for reliable automotive use. Low maximum reverse leakage current of 200 nA enhances efficiency.
