SZMMBZ5258BLT1G Description

Short technical summary and product information.

The SZMMBZ5258BLT1G is a Zener diode from the MMBZ52xxBLT1G / SZMMBZ52xxBLT1G series, designed for voltage regulation in space-constrained applications. It is housed in a small SOT-23-3 (TO-236) surface mount package, ideal for high density PCBs.

 

Key electrical characteristics include a nominal Zener voltage of 36V with ±5% tolerance, maximum power dissipation of 225mW on FR-5 board, and a maximum forward voltage of 900mV at 10mA. Reverse leakage current is limited to 100nA at 27V, and Zener impedance is 70Ω maximum at the test current.

 

The device operates over a junction temperature range of -65°C to 150°C, with thermal resistance of 556°C/W on FR-5 and 417°C/W on alumina substrate. It features an ESD rating of Class 3 (>16kV) per the Human Body Model, and the case is void-free transfer-molded thermosetting plastic with UL 94 V-0 flammability rating.

 

This part is RoHS compliant, Pb-Free, and Halogen Free/BFR Free. The SZ prefix indicates AEC-Q101 qualification, making it suitable for automotive applications requiring strict change control and PPAP capability.
