1N5344BG

Single Zener Diodes Overview

The onsemi 1N5344BG is a single Zener diode from the 1N53 Series, housed in an axial lead Surmetic 40 (Case 017AA) plastic package. It provides a nominal reverse Zener voltage of 8.2 V with a tolerance of ±5%. The device features a maximum steady-state power dissipation of 5 W at a lead temperature of 25°C and operates within a junction temperature range of -65°C to +200°C. Key electrical parameters include a test current of 150 mA, a maximum Zener impedance of 1.5 Ohms at IZT, and a maximum reverse leakage current of 10 µA at VR.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'G' corresponds to the Pb-Free package configuration as specified in the datasheet. Confirm the specific package variant matches the required mechanical dimensions for Case 017AA. Ensure compliance with RoHS directives if applicable to the target market. Cross-reference the part number with official manufacturer documentation to validate availability and revision status before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 8.2 V reference is required with a 5 W power handling capacity. The axial lead format facilitates through-hole mounting in standard environments. Consider the thermal resistance characteristics and derating requirements above 25°C for continuous operation. Verify that the ±5% voltage tolerance meets the precision requirements of the specific application circuit design.

Single Zener Diodes Part Context

This device belongs to the 1N53 Series of 5 Watt Zener Voltage Regulators manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, all sharing the same Surmetic 40 axial lead package. The 1N5344B specifically targets the 8.2 V segment of this lineup, offering consistent performance metrics aligned with the broader family specifications for industrial and commercial applications.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same series include 1N5344BRLG (Reel/Cut Tape packaging) and 1N5344BG (Bulk packaging). These variants share identical electrical characteristics and mechanical footprint, differing only in shipping configuration. Ensure any replacement maintains the Pb-Free designation if environmental compliance is mandated.
