The 1N748A is a 3.9V Zener diode manufactured by On Semiconductor, designed for voltage regulation and reference applications. It features a nominal Zener voltage of 3.9V at a test current of 20mA with a tolerance of ±5%. The device can dissipate up to 500mW of power at lead temperatures up to 75°C, with a derating factor of 4.0mW/°C above that.
Electrical characteristics include a maximum impedance of 23Ω at the test current, a maximum Zener current of 95mA, and a reverse leakage current of 10µA at 1V. The forward voltage is 1.5V maximum at 200mA. The diode operates over a junction temperature range of -65°C to 200°C.
The 1N748A is housed in a DO-35 glass case with axial leads, suitable for through-hole mounting. The cathode is identified by a color band. This device is part of the 1N746A-1N759A series of Zener diodes offering voltages from 2.4V to 12V.
The nominal Zener voltage is 3.9V at a test current of 20mA.
The power dissipation is 500mW at lead temperatures up to 75°C, derated at 4.0mW/°C above that.
The 1N748A is available in a DO-35 glass through-hole package with axial leads.
The maximum forward voltage is 1.5V at a forward current of 200mA.
The operating and storage temperature range is -65°C to 200°C.
