Product Description
STMicroelectronics SM6T39AY is a high-performance 1-element uni-directional transient voltage suppressor diode delivering robust 600W peak pulse power dissipation. It is encapsulated in a compact DO-214 surface mount package with 2 pins optimized for automotive electronic circuit protection.
Designed according to AEC-Q101 automotive standards, this diode effectively safeguards sensitive automotive circuits against voltage transients and electrostatic discharges. It supports a minimum breakdown voltage of 37.1V and a maximum reverse stand-off voltage of 33.3V, with a clamping voltage specification of 69.7V, ensuring precise voltage suppression in high-stress environments.
With a maximum peak pulse current of 57A and a low leakage current rating of 1μA, it maintains energy absorption capacity while minimizing power dissipation losses. The device can operate in harsh temperature conditions ranging from -55°C up to 150°C, making it suitable for automotive and industrial applications.
The diode’s small footprint (4.6 mm length, 3.95 mm width, and 2.45 mm height) allows for efficient PCB space utilization, ideal for modern automotive electronic designs. The SM6TY series to which this diode belongs is tailored to meet standards ISO 7637-2 and ISO 10605 for transient voltage suppression.
