1N4737AP/TR12

Overview

The Microchip Technology 1N4737AP/TR12 is a silicon 1-watt Zener diode in the 1N4728AP through 1N4764AP series. It provides voltage regulation with a nominal Zener voltage of 7.5 V and a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features flexible axial-lead mounting terminals in a DO-41 plastic package.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard installation
• Constructed with a void-free transfer molded thermosetting epoxy body

Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Procurement Notes

Verify that the specific part number matches the required datasheet revision and manufacturer specifications. Confirm compliance requirements such as RoHS status if applicable, and ensure the ordering suffix aligns with the desired packaging configuration before finalizing procurement orders.

Selection Notes

Select this component when a 7.5 V reference with 5% tolerance is required. Ensure the circuit design accommodates the maximum power dissipation limits and thermal resistance characteristics. Verify that the operating temperature range meets the environmental conditions of the intended application.

Part Context

This component belongs to the JEDEC registered 1N4728A to 1N4764A series of 1.0 watt Zener diodes. The series offers an extensive voltage selection from 3.3 to 100 volts. The 'P' suffix indicates plastic construction, which provides lower thermal resistance compared to glass-body options.

Replacement Considerations

Surface mount equivalents are available as SMAJ4737A or MLL4737A. Consult the factory for other surface mount options or military screening levels.
