Overview
The Microchip Technology 1N4752UR-1/TR is a surface mount glass Zener diode with a nominal voltage of 33 V and a power dissipation rating of 1.0 W at 25 °C. It utilizes the DO-213AB (MELF) package and operates within a temperature range of -65 °C to +175 °C. Electrical characteristics include a maximum dynamic impedance of 45 Ohms, a maximum reverse current of 5 µA at 25.1 V, and a maximum regulator current of 135 mA at 50 °C ambient temperature.
Feature Summary
- Hermetically sealed glass MELF package for high reliability applications
- Surface mount design suitable for high density mounting
- Inherently radiation hard per MicroNote 050
- ESD nonsensitive construction
Applications
- Voltage regulation in high density circuits
- High reliability applications requiring source control drawings
- Low parasitic requirement environments
Procurement Notes
Verify the specific suffix requirements against the manufacturer's datasheet to ensure correct tolerance and packaging options. Confirm RoHS compliance status if required by project specifications. Check for availability of alternative screening prefixes such as MQ or MX for military-grade variants. Ensure the ordering quantity aligns with standard tape and reel configurations.
Selection Notes
Select this component when a surface mount equivalent to the axial 1N4752A is needed. The device offers a standard 5% voltage tolerance. Consider the thermal resistance values for PCB layout planning. Verify that the operating current remains within the specified limits for the intended ambient temperature conditions.
Part Context
This part belongs to the 1N4728UR through 1N4764AUR series of surface mountable 1 watt Zener diodes. These devices are electrically equivalent to their JEDEC registered DO-41 counterparts but utilize the DO-213AB outline. The series covers Zener voltages from 3.3 V to 100 V, providing a wide selection for various regulation needs.
Replacement Considerations
Direct surface mount equivalents include MLL4752A. Axial leaded replacements include the 1N4752A. Plastic body equivalents are available as SMAJ4752A.
