1N4736UR/TR

Overview

The Microchip Technology 1N4736UR/TR is a surface mount glass Zener diode in the DO-213AB MELF package. It provides a nominal Zener voltage of 6.8V with a standard tolerance of ±5%. The device operates at a test current of 37mA and features a maximum dynamic impedance of 3.5 Ohms. It dissipates up to 1.0W of power, with a maximum reverse leakage current of 10µA at 4V. The component supports an operating temperature range from -65°C to +175°C.

Feature Summary

• Hermetically sealed glass construction for high reliability applications
• Surface mount design suitable for high density mounting
• Inherently radiation hard per MicroNote 050

Applications

• Voltage regulation in high density circuits
• Low parasitic requirement applications
• High reliability systems requiring source control drawings

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance levels and screening options. Confirm that the TR suffix indicates tape and reel packaging as specified in the mechanical data. Ensure compatibility with JEDEC outline DO-213AB requirements for your PCB footprint design.

Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required for robust performance. The DO-213AB package offers a leadless form factor ideal for automated assembly processes. Consider the wide operating temperature range and radiation hardness for demanding environments where standard plastic packages may be insufficient.

Part Context

This part belongs to the 1N4728AUR through 1N4764AUR series of 1-watt glass Zener diodes manufactured by Microsemi (now Microchip Technology). These devices are electrically equivalent to the registered 1N4728A through 1N4764A axial-leaded series but utilize the DO-213AB surface mount outline. The series covers Zener voltages from 3.3V to 100V.
