MMSZ5261BT1G Description

Short technical summary and product information.

The MMSZ5261BT1G is a Zener voltage regulator diode from On Semiconductor, part of the MMSZ52xxxT1G series. It offers a nominal Zener voltage of 47V with a tolerance of ±5% and a maximum power dissipation of 500mW on FR-5 board. The device features a maximum impedance (Zzt) of 105Ω and a reverse leakage current of 100nA at 36V. Forward voltage is 900mV at 10mA. The diode is designed for general purpose medium current applications and is suitable for voltage regulation and protection circuits. It comes in a surface mount SOD-123 package, which is optimized for automated board assembly. The operating temperature range is -55°C to 150°C. The device is Pb-Free and has an ESD rating of Class 3 (>16kV) per Human Body Model. Thermal resistance junction-to-ambient is 340°C/W and junction-to-lead is 150°C/W. The flammability rating is UL 94 V-0.
