SZMMBZ5256BLT1G

Single Zener Diodes Overview

The SZMMBZ5256BLT1G is a single Zener voltage regulator diode from the SZMMBZ52xxBLT1G series, manufactured by onsemi. It provides a nominal Zener voltage of 30 V with a tolerance range of 28.50 V to 31.50 V at a test current of 4.2 mA. The device features a maximum Zener impedance of 49 Ohms and a reverse leakage current of 0.1 µA at 23 V. It operates within a junction temperature range of -65°C to +150°C and dissipates up to 225 mW on an FR-5 board. Packaged in a surface-mount SOT-23 (CASE 318) housing, it is designed for high-density applications.

High density PC boards

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the specific automotive qualification requirements. Confirm the component is Pb-Free, Halogen Free, and BFR Free as stated in the datasheet. Ensure the application environment supports the specified thermal dissipation limits on the target substrate material.

Single Zener Diodes Selection Notes

Select this component when a 30 V regulation point is required in a compact form factor. The SZ prefix is necessary if the design mandates AEC-Q101 qualification or specific supply chain controls. Consider the 49 Ohm impedance for dynamic load performance and verify the forward voltage characteristics if bidirectional protection is not intended.

Single Zener Diodes Part Context

This part belongs to the MMBZ52xxBLT1G and SZMMBZ52xxBLT1G series of Zener diodes. These devices are silicon unidirectional voltage regulators designed for low-power regulation tasks. The series covers a wide voltage range from 2.4 V to 91 V, all housed in the same small plastic SOT-23 package to simplify inventory management for designers.
