1N5248B-TR Description

Short technical summary and product information.

The 1N5248B-TR is a small signal Zener diode from Vishay Dale, part of the 1N5221 to 1N5267 series. It provides a nominal Zener voltage of 18V with ±5% tolerance.

 

Key electrical characteristics include a maximum power dissipation of 500mW at lead temperature ≤25°C, a maximum forward voltage of 1.1V at 200mA, and a maximum Zener impedance of 21Ω at the test current. Reverse leakage current is limited to 100nA at 14V reverse voltage.

 

The device is housed in a DO-35 (DO-204AH) axial-lead package, suitable for through-hole mounting. It features a junction temperature range up to 175°C and storage temperature from -65°C to +175°C. Thermal resistance junction-to-ambient is 300 K/W.

 

Typical applications include voltage stabilization circuits. The component is RoHS3 compliant and has MSL level 1 (unlimited).
