The Vishay SML4738A-E3/61 is a 8.2V Zener diode from the SML47xxA series, designed for surface mount applications. It features a nominal Zener voltage of 8.2V with ±5% tolerance, making it suitable for voltage regulation and reference circuits. The device can dissipate up to 1W of power at a lead temperature of 75°C, with a maximum junction temperature of 150°C.
This Zener diode offers low dynamic impedance of 4.5Ω at the test current of 31mA, ensuring stable voltage regulation under varying current conditions. The reverse leakage current is limited to 10µA at a reverse voltage of 6V. The DO-214AC (SMA) package is compatible with standard surface mount assembly processes and is rated MSL Level 1 (unlimited) per J-STD-020.
The part is RoHS compliant with matte tin termination finish. It is a commercial grade device and is not AEC-Q101 qualified, though the HE3 suffix variant is available for automotive applications. Suitable for general purpose voltage regulation, overvoltage protection, and reference voltage generation in consumer and industrial electronics.
