PSSI2021SAY Datasheet Constant Current Source

Manufacturer: Philips Semiconductors (now NXP Semiconductors)

Overview: DISCRETE SEMICONDUCTORS DATA SHEET k, halfpage MBD127 PSSI2021SAY Constant current source Product specification 2001 May 07 Philips Semiconductors Product specification Constant current.

General Description

Resistor equipped PNP transistor with two diodes on one chip in a plastic SC-88A package.

Built-in bias resistor and two diodes allow operation as constant current source.

The stabilized current can be adjusted between 15 µA and 50 mA by connection of external resistors between pins 4 and 5.

Key Features

  • One chip constant current source.
  • Reduced number of components and board space.
