Overview
The MMBZ5259BTW_R1_00001 is a surface mount silicon Zener diode from the Panjit MMBZ5221BTW to MMBZ5267BTW series. It features a nominal Zener voltage of 39V with a tolerance range of 37.05V to 40.95V. The device operates within a power dissipation rating of 200mW and supports an operating junction temperature range of -55°C to +150°C. Packaged in a compact SOT-363 plastic case, it includes three isolated elements suitable for automated assembly processes.
Feature Summary
- Planar die construction designed for high reliability
- Low profile SOT-363 package optimized for board space efficiency
- Lead-free composition compliant with EU RoHS 2.0 directives
- Green molding compound meeting IEC 61249 standards
Applications
- Voltage regulation in portable electronic devices
- Protection circuits in handheld computers
- Reference voltage sources in digital instrumentation
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm reel quantity and tape specifications. Ensure compliance with environmental directives such as RoHS 2.0 and IEC 61249 when sourcing components for regulated markets. Confirm solderability requirements align with MIL-STD-750 Method 2026 standards during procurement planning.
Selection Notes
Select this component when a 39V Zener reference is required in a triple-isolated SOT-363 footprint. Consider the 200mW power dissipation limit and the maximum reverse leakage current of 30µA at 30V when designing biasing networks. Evaluate thermal derating curves if operation exceeds standard ambient temperatures.
Part Context
This part belongs to the MMBZ52xxBTW family of triple isolated Zener diodes manufactured by Panjit International Inc. The series offers various voltage options ranging from 2.4V to 75V within the same SOT-363 package form factor, facilitating standardized inventory management across different circuit designs requiring multiple voltage references.
Replacement Considerations
Cross-reference with other MMBZ5259 variants or equivalent triple Zener packages from other manufacturers ensuring identical pinout and electrical characteristics. Verify that substitute parts meet the same 200mW power rating and SOT-363 mechanical dimensions.
