Overview
The Microchip Technology 1N4750APE3/TR8 is a silicon 1.0-watt Zener diode housed in a plastic DO-41 (DO-204AL) axial-lead package. It provides voltage regulation with a nominal Zener voltage of 27 volts and a standard tolerance of plus or minus 5%. The device operates within a temperature range of -65°C to +150°C and features RoHS compliance indicated by the e3 suffix.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Features flexible axial-lead mounting terminals for through-hole applications
- Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
Applications
- Voltage reference circuits
- Overvoltage protection systems
- General-purpose voltage regulation
Procurement Notes
Verify that the ordering suffix TR8 corresponds to the tape and reel packaging configuration as specified in the manufacturer documentation. Confirm the presence of the e3 suffix to ensure the device meets RoHS compliance requirements. Cross-reference the part number against official Microchip Technology databases to validate authenticity and current production status before procurement.
Selection Notes
Select this component when a 27-volt regulation point is required with a 5% tolerance. Ensure the application environment stays within the specified -65°C to +150°C operating temperature range. Verify that the 1.0-watt power dissipation rating at 25°C aligns with the thermal management capabilities of the target circuit board layout.
Part Context
This component belongs to the 1N4728AP through 1N4764AP series of 1.0-watt Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series offers an extensive voltage selection from 3.3 to 100 volts. The specific model utilizes a plastic encapsulation option which provides lower thermal resistance compared to glass-body alternatives within the same JEDEC numbering system.
Replacement Considerations
Compatible substitutes include other 1N4750A variants with matching electrical characteristics. Devices such as the 1N4750A-T3-LF offer equivalent specifications. Ensure any replacement maintains the DO-41 package form factor and 27-volt Zener voltage rating.
