• Reference Type: Shunt
• Output Voltage: 1.22V (fixed)
• Output Current: 20 mA
• Tolerance: ±1%
• Temperature Coefficient: 75ppm/°C
• Noise Performance: 60µVrms (10Hz to 10kHz)
• Cathode Current: 8 µA
• Operating Temperature Range: -40°C ~ 85°C
• Package: SOT-23-3
• Compliance: ROHS3, MSL 1

The ZXRE125DFTA meets all substitution criteria as a parametric equivalent, maintaining identical electrical specifications and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ZXRE125DFTA is a direct parametric equivalent to the ZXRE1004DFTA and is suitable for new designs and production transitions. The primary distinction is product status: the ZXRE1004DFTA is in Last Time Buy phase, while the ZXRE125DFTA maintains Active status with confirmed inventory availability (9080 Pcs). Both parts carry identical ROHS3 compliance and MSL 1 ratings, ensuring equivalent environmental and handling requirements. Selection of the ZXRE125DFTA eliminates obsolescence risk while maintaining full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)
