1N5221B-TR Description

Short technical summary and product information.

The Vishay Dale 1N5221B-TR is a small signal Zener diode designed for voltage stabilization applications. It features a nominal Zener voltage of 2.4V with a ±5% tolerance, indicated by the 'B' suffix in the part number. The device is rated for a maximum power dissipation of 500mW at a lead temperature of 25°C.

 

Electrical characteristics include a Zener test current of 20mA, a maximum dynamic resistance of 30Ω at the test current, and a maximum reverse leakage current of 0.25µA at 1V reverse voltage. The forward voltage is specified at a maximum of 1.1V at 200mA forward current. The device has a typical temperature coefficient of -0.085%/K.

 

The 1N5221B-TR is housed in a DO-35 (DO-204AH) axial lead package, suitable for through-hole mounting. It has a maximum junction temperature of 175°C and a storage temperature range of -65°C to +175°C. The device is RoHS3 compliant and has an MSL rating of 1 (unlimited).
