1N4740A-TR Description

Short technical summary and product information.

The 1N4740A-TR is a Zener diode from Vishay Dale offering a nominal Zener voltage of 10V with a tolerance of ±5%. It is rated for a maximum power dissipation of 1.3W (1300 mW) at an ambient temperature of 25°C, with leads kept at a distance of 4 mm from the case. This device is part of the 1N4728A-1N4761A series of silicon planar power Zener diodes designed for voltage stabilization and clipping circuits. The Zener impedance is typically 7 Ω at 25 mA test current. Maximum reverse leakage current is 10 µA at 7.6V reverse voltage. The maximum forward voltage is 1.2V at 200 mA forward current. The junction temperature can reach up to 175°C, with a storage temperature range of -65°C to +175°C. The 1N4740A-TR is housed in a DO-41 (DO-204AL) axial-leaded package, suitable for through-hole mounting. The -TR suffix indicates tape and reel packaging for automated assembly. The device is rated MSL level 1 (unlimited) and is RoHS3 compliant (unverified).
