1N4896/TR

Overview

The Microchip Technology 1N4896/TR is a single temperature-compensated Zener diode designed for precision voltage reference applications. It features a nominal Zener voltage of 12.8 V with a tight tolerance of ±5%. The device operates in the DO-7 (DO-204AA) axial through-hole package and dissipates up to 400 mW. Key electrical characteristics include a maximum Zener impedance of 400 Ohms, a test current of 500 uA, and a low voltage temperature coefficient of 0.001 %/°C. It supports an operating temperature range from -65°C to +175°C.

Feature Summary

Temperature compensated design ensures stable voltage regulation across wide thermal variations
Precision voltage reference capability with tight manufacturing tolerance
Robust axial leaded construction suitable for high-reliability through-hole mounting

Applications

Precision voltage reference circuits requiring thermal stability
Temperature compensation networks in analog signal conditioning
High-reliability industrial control systems

Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging configuration. Confirm RoHS compliance status as documentation may vary by production batch. Ensure the DO-7 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a stable 12.8 V reference is required under varying thermal conditions. The low temperature coefficient makes it superior to standard Zener diodes for precision applications. Verify that the 400 mW power dissipation rating meets the circuit's thermal management needs.

Part Context

This part belongs to the 1N489x series of temperature-compensated Zener diodes manufactured by Microchip Technology. These devices are engineered to provide highly stable voltage references by utilizing specific doping profiles that counteract natural temperature drifts inherent in silicon junctions.
