1N4736CE3/TR13

Overview

The Microchip Technology 1N4736CE3/TR13 is a silicon 1.0-watt Zener diode in the 1N4728AP through 1N4764AP series, housed in a plastic DO-41 (DO-204AL) axial-lead package. It provides voltage regulation with a nominal Zener voltage of 6.8 V and a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and features RoHS-compliant annealed matte-tin plating on its terminals.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole applications
• Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards

Applications

• Voltage reference circuits requiring precise regulation
• Power supply protection against overvoltage conditions
• General-purpose voltage clamping in electronic systems

Procurement Notes

Verify that the component matches the specific JEDEC type number and suffix requirements for your design. Confirm the RoHS compliance status and terminal plating specifications align with environmental regulations. Ensure the tape and reel packaging meets handling requirements for automated assembly processes.

Selection Notes

Select this component when a 6.8 V regulation point with high precision is required. The ±2% tolerance offers tighter control than standard 5% or 10% variants. Consider the thermal resistance characteristics and power derating curves if operating near maximum ratings or in enclosed environments.

Part Context

This part belongs to the widely used 1N47xxA series of 1-watt Zener diodes. The 'e3' suffix denotes RoHS compliance with tin-plated terminals, while the 'TR13' indicates tape and reel packaging. The 'C' suffix specifies the 2% voltage tolerance, distinguishing it from the standard 'A' (5%) or unmarked (10%) versions.

Replacement Considerations

Compatible substitutes include other 1N4736 variants with matching voltage and tolerance, such as 1N4736A (5% tolerance) or 1N4736D (1% tolerance). Surface mount equivalents like SMAJ4736A are available for different form factors.
