Product Description
STMicroelectronics 1.5KE47A is a 1-element uni-directional transient voltage suppression (TVS) diode designed for protecting sensitive electronic equipment from voltage transients such as induced lightning and switching surges. Rated at 1.5 kW peak pulse power dissipation, this device features a robust 2-pin DO-201 through-hole package enabling easy mounting on printed circuit boards.
The diode provides a minimum breakdown voltage (Vbr) of 44.7 volts and a maximum reverse stand-off voltage (Vwm) of 40.2 volts, ensuring high reliability in voltage transient suppression. With a clamping voltage (Vc) of 84 volts, it effectively clamps voltage spikes to safe levels, preventing damage to downstream components.
Its operating temperature range from -65°C to 175°C allows usage in demanding industrial, automotive, and commercial electronic applications. The low maximum reverse leakage current of 1 microampere ensures minimal power loss during normal operation, while the device supports a peak pulse current (Ippm) of up to 119 amperes.
The compact size with dimensions approximately 9.5 mm in length and 5.3 mm in diameter makes it suitable for space-constrained applications. The diode is ideal for general-purpose transient surge protection in power supplies, communication equipment, and consumer electronics.
Single element uni-directional TVS diode for reliable transient voltage suppression. 1.5 kW peak pulse power dissipation rating supports high surge energy capability. Wide operating temperature range ensures performance in harsh environments.
