Overview
The MMBZ5249BTW_R1_00001 is a surface mount silicon Zener diode from the Panjit MMBZ5221BTW to MMBZ5267BTW series. It features a nominal Zener voltage of 19V with a tolerance range of 18.05V to 19.95V at an test current (IZT) of 6.6mA. The device has a maximum power dissipation of 200mW and operates within a junction temperature range of -55°C to +150°C. It utilizes a SOT-363 plastic package and includes a specific marking code J4 for identification.
Feature Summary
- Planar die construction designed for automated assembly processes
- Compliant with EU RoHS 2.0 lead-free standards
- Utilizes green molding compound per IEC 61249 standard
Applications
- Voltage regulation in portable instrumentation
- Protection circuits in handheld computers
- Reference voltage sources in digital cameras
Procurement Notes
Verify the component against the official datasheet specifications, specifically the 19V nominal voltage and SOT-363 package dimensions. Confirm compliance requirements such as RoHS 2.0 and IEC 61249 green molding standards. Ensure the marking code matches J4 for accurate part identification during incoming inspection.
Selection Notes
Select this component when a 19V Zener reference is required in space-constrained designs utilizing the SOT-363 footprint. Consider the 200mW power dissipation limit and the specific impedance characteristics at 6.6mA test current. Evaluate thermal derating curves if operating near the upper temperature limits.
Part Context
This part belongs to the MMBZ5221BTW through MMBZ5267BTW series, which covers Zener voltages from 2.4V to 75V. All members share identical mechanical data, including the SOT-363 case and solderability per MIL-STD-750 Method 2026. The series is optimized for low-profile applications requiring reliable voltage clamping.
Replacement Considerations
Direct replacements must match the 19V nominal voltage, 200mW power rating, and SOT-363 package. Verify that alternative suppliers provide components with equivalent Zener impedance and leakage current specifications to ensure circuit performance consistency.
