onsemi 4.3 V 1.5 W Zener Diode Surface Mount 2-Pin SMA 1SMA5916BT3G

onsemi 1SMA5916BT3G is a single element Zener diode designed for precise voltage regulation applications with a nominal Zener voltage of 4.3 V and a power dissipation rating of 1.5 W. This diode is mounted in a surface-mount SMA package offering a compact footprint and low profile, ideal for space-constrained electronic circuit designs.

This diode features a ±5% voltage tolerance ensuring stable regulation within its range. It operates at a maximum temperature of 150°C, suitable for robust industrial and automotive electronics environments. The package is designed with corrosion resistant finishes and solderable leads, facilitating reliable PCB mounting. The device also complies with the AEC-Q101 automotive standard, certifying its use in automotive electronic applications where durability under stress is critical.

Electrical characteristics include a maximum Zener impedance of 500 Ω, a test current of 87.2 mA to verify proper conduction, and a very low maximum reverse leakage current of 2.5 μA, which reduces leakage power and enhances efficiency. The diode package is designed for either top side or bottom circuit board mounting and provides ease of handling due to its flat handling surface. It is an excellent replacement for older MELF packages while improving mechanical stability and manufacturing throughput.

Mechanical properties include a case built from void-free transfer-molded plastic, with a height of 2.2 mm and a length of 5.59 mm. The maximum case temperature for soldering purposes is specified as 260 °C for 10 seconds, allowing compatibility with standard soldering processes. Polarity is clearly marked to prevent assembly errors.

Applications for the onsemi 1SMA5916BT3G include industrial voltage regulation, automotive electronic circuits, and other manufacturing or electronic board production requiring reliable and efficient Zener diode voltage regulation.
