1N4753APE3/TR12

Overview

The Microchip Technology 1N4753APE3/TR12 is a silicon 1.0-watt Zener diode in the JEDEC-registered 1N4728A to 1N4764AP series. It provides voltage regulation with a nominal Zener voltage of 36 V and a standard tolerance of ±5%. The device features a plastic DO-41 (DO-204AL) axial lead package, RoHS compliance via the e3 suffix, and tape-and-reel packaging per EIA-296. Electrical characteristics include a maximum dynamic impedance of 50 Ohms at a test current of 7.0 mA, a maximum reverse current of 5 µA at 27.4 V, and an operating temperature range from -65°C to +150°C.

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
• Non-sensitive to electrostatic discharge as verified by MIL-STD-750 Method 1020

Applications

• General purpose voltage regulation circuits
• Power supply reference voltage generation
• Overvoltage protection stages
• Temperature compensation networks

Procurement Notes

Verify that the specific ordering suffix matches the required package style and environmental compliance. Confirm the manufacturer source, as this component originates from the Microsemi Scottsdale Division now part of Microchip Technology. Ensure the reel quantity aligns with production requirements, as the TR12 suffix indicates a specific tape and reel configuration. Check for any military screening prefixes if higher reliability levels are needed for the application.

Selection Notes

Select this component when a 36 V regulation point with ±5% tolerance is required in a 1 W power dissipation class. The plastic DO-41 package offers lower thermal resistance compared to glass-body options. Consider the RoHS compliant e3 suffix for modern manufacturing environments. Evaluate the 50 Ohm dynamic impedance and 5 µA reverse leakage against circuit sensitivity requirements. Verify compatibility with the specified operating temperature range of -65°C to +150°C.

Part Context

This device belongs to the popular 1N4728A through 1N4764AP series of silicon Zener diodes. The series covers a wide voltage selection from 3.3 V to 100 V. The 'P' suffix designates the plastic encapsulated construction, while the 'e3' suffix confirms RoHS compliance with annealed matte-tin plating. These components are moisture classified as Level 1, eliminating the need for dry packing during storage and handling.

Replacement Considerations

Surface mount equivalents are available as SMAJ4753A or MLL4753A. For glass-body replacements, consult the separate datasheet for G suffix options. Military screening variants may require adding MQ, MX, MV, or MSP prefixes to the base part number.
