1N4736A_NT50A

Overview

The onsemi 1N4736A_NT50A is a silicon unidirectional voltage regulator diode housed in the DO-41 glass case. It provides a nominal Zener voltage of 6.8 V with a 5% tolerance, tested at a current of 37 mA. The device dissipates up to 1 W of power and maintains operation across a temperature range from -65°C to +200°C. Key electrical characteristics include a maximum Zener impedance of 3.5 Ω at the test current and a leakage current not exceeding 10 µA at 1 V reverse voltage.

Feature Summary

• Provides stable voltage regulation using a single silicon junction
• Features a robust glass encapsulation for thermal stability
• Designed for high surge current handling capabilities

Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping applications

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and marking details. Confirm RoHS compliance status and lead-free availability directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when a precise 6.8 V reference is required within a standard through-hole form factor. Ensure the circuit design accommodates the specified 37 mA test current and that the operating environment remains within the defined temperature limits.

Part Context

This part belongs to the 1N4728A through 1N4758A series published by Semiconductor Components Industries, LLC (dba ON Semiconductor). The series covers a wide range of Zener voltages from 3.3 V to 56 V, all sharing common physical dimensions and general electrical testing conditions.

Replacement Considerations

Cross-reference with other manufacturers' 1N4736A equivalents. Verify that substitute parts meet the same 6.8 V nominal voltage, 5% tolerance, and 1 W power dissipation ratings.
