1N4756A_T50R

Overview

The onsemi 1N4756A_T50R is a silicon planar Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 47 V with a tolerance of ±5%. The device operates within a power dissipation rating of 1.0 W and supports an operating temperature range from -65°C to +200°C. Electrical characteristics include a maximum Zener impedance of 80 Ω at the test current of 5.5 mA, and a leakage current not exceeding 5 µA at 35.8 V reverse voltage. The component utilizes a DO-41 glass axial leaded package.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Features hermetically sealed glass construction in a DO-41 package
• Supports high junction temperatures up to 200°C

Applications

• Voltage reference circuits
• Overvoltage protection
• Clipper and clamper circuits

Procurement Notes

Verify the specific ordering suffix _T50R against official documentation to confirm tape-and-reel packaging configuration. Ensure that the manufacturer designation matches Semiconductor Components Industries, LLC (dba ON Semiconductor). Confirm RoHS compliance status and REACH SVHC declarations prior to procurement integration.

Selection Notes

Select this component when a 47 V regulated voltage point is required in through-hole designs. The DO-41 package facilitates standard PCB mounting. Verify that the 1.0 W power dissipation capability meets thermal requirements under expected load conditions. Consider the 80 Ω impedance value for dynamic regulation performance needs.

Part Context

This part belongs to the 1N4728A through 1N4758A series of one-watt Zener diodes manufactured by ON Semiconductor. The series covers a wide voltage range from 3.3 V to 100 V. These devices are characterized by double-slug type construction and oxide passivated dies, ensuring reliability across industrial temperature ranges.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4756A equivalents in DO-41 packages. Verify pinout compatibility and electrical parameter alignment, specifically Zener voltage tolerance and power dissipation ratings, before substitution.
