Vishay SML4749AHE3_A/H Zener Diode is a single-element, surface-mounted semiconductor device designed to provide voltage regulation with nominal Zener voltage of 24 volts. Packaged in an SMA (DO-214AC) form factor, this diode offers 1 watt maximum power dissipation and ±5% voltage tolerance, making it suitable for general-purpose voltage reference and protection applications.
The 2-pin surface mount device features low impedance at 25 ohms and a minimal reverse leakage current of 5 microamperes, ensuring efficient performance in circuits requiring stable voltage control. Its operating temperature range between -65°C and +150°C supports functionality in both industrial and automotive environments.
Certified to meet automotive standard AEC-Q101 and complying with RoHS and IEC 61760-1 and IEC 61000-4-2 standards, it guarantees high reliability and environmental safety. The diode withstands high-temperature soldering of up to 260 °C for 10 seconds at terminals, ensuring robust assembly during PCB manufacturing.
This Zener diode finds applications across industrial electronic systems, power supplies, voltage regulation modules, protective circuits, automotive electronics, telecommunications equipment, and general semiconductor assemblies where voltage stabilization is critical.
Nominal Zener voltage of 24 volts for precise voltage regulation. Maximum power dissipation rated at 1 watt suitable for moderate power applications. Surface mount configuration with 2-pin SMA (DO-214AC) package ensures easy PCB integration.
±5% Zener voltage tolerance guarantees consistent performance. Operates in temperature range from -65°C to 150°C for reliability under harsh conditions. Low maximum Zener impedance of 25 ohms enhances voltage stability. Maximum reverse leakage current is only 5 microamperes minimizing leakage losses.
Test current specified at 10.5 milliamperes for accurate characterization. Compliance with RoHS and IEC standards ensures quality and environmental safety. Automotive standard AEC-Q101 certified for use in automotive electronics.
