Overview
The Microchip Technology 1N4760AUR/TR is a surface mountable 1.0 W glass Zener diode in the DO-213AB (MELF) package. It provides a nominal Zener voltage of 68 V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +175°C and features a maximum dynamic impedance of 150 Ohms at a test current of 3.7 mA. It includes a maximum reverse current of 5 µA at 51.7 V and supports a maximum regulator current of 13 mA.
Feature Summary
- Hermetically sealed glass MELF package for high reliability
- Surface mount design suitable for high density mounting
- Inherently radiation hard per MicroNote 050
- Wide operating temperature range from -65°C to +175°C
Applications
- Voltage regulation in high density circuits
- High reliability applications requiring source control drawings
- Low parasitic requirement environments
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm compliance requirements, such as RoHS status or screening levels. Confirm that the TR suffix indicates tape and reel packaging. Ensure the part number matches the exact electrical characteristics required for the target application before procurement.
Selection Notes
Select this component when a 68 V Zener voltage is required in a surface mount form factor. Consider the ±5% tolerance and 150 Ohm dynamic impedance for circuit stability. Evaluate the thermal resistance and derating curves if operating near the maximum power dissipation limits on FR4 PCBs.
Part Context
This part belongs to the 1N4728AUR through 1N4764AUR series of surface mount 1.0 W glass Zener diodes. It is electrically equivalent to the JEDEC registered 1N4728A through 1N4764A axial leaded series but utilizes the DO-213AB outline. The series covers Zener voltages from 3.3 V to 100 V.
Replacement Considerations
Direct equivalents include the 1N4760A axial leaded version for through-hole applications. Surface mount alternatives may include other manufacturers' DO-213AB packages with matching 68 V and 1 W ratings.
