LSJ511
Current Regulator Diode
Linear Systems replaces discontinued Siliconix LSJ511
The Linear Systems J511 is a ± 20% range current regulator
FEATURES
The LSJ511 is a ±20% range current regulator
REPLACEMENT SECOND SOURCE FOR SILICONIX J511
WIDE CURRENT RANGE
designed for demanding applications in test equipment
and instrumentation. The LSJ511 utilizes JFET

1. Absolute Maximum ratings are limiting values above which serviceability may be impaired
2. Pulsed, t = 2ms. Maximum VF where IF < 1.1 IF(MAX)
3. Pulsed, t = 2ms. Continuous currents may vary.
4. Pulsed, t = 2ms. Continuous impedances may vary.
5. Min VF required to ensure IF = 0.8 IF(MIN)
