The ZXRE250/2 are three terminal adjustable shunt regulators offering excellent temperature stability and output current handling capability up to 100mA.

These devices feature a very low cathode current for regulation, typically 40μA.

They provide a low power enhancement to industry standard ‘431 parts. Available as standard A grade (1 tolerance) and B grade (0.5 tolerance), all with a -40oC to 125oC temperature range as standard.

The ZXRE250 is available in 3-pin and 5-pin versions of SOT23, ZXRE252 offers a reverse pinout in SOT23. The ZXRE250/2 can be used as a replacement for Zener diodes in many applications requiring an improvement in Zener performance.

The Diodes advantage

■ Very low minimum cathode current for regulation; 40μA typical

Ensures minimum power dissipation in applications such as idle

power for ACDC external PSU’s for laptop PC’s

■ Wide temperature range: -40 to 125oC

Simplifies component choice and stocking

■ Maximum cathode voltage of 36V

Matches industry standard ‘431; allowing it to be used in a wide

range of applications

■ Available in SOT23 and SOT25 with green (no Br, Sb) molding compound

Environmentally friendly small surface mount package variants

■ 0.5 and 1 variants in all package options

Meets requirements of modern equipment
