2N5264

Overview

The Microchip Technology 2N5264 is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 10 V with a tolerance of ±5%. The device operates within a temperature range of -65°C to +175°C and utilizes a DO-35 axial leaded package. Key electrical characteristics include a maximum reverse leakage current of 5 µA at the rated voltage and a test current of 20 mA. The component is qualified under MIL-PRF-19500/118 standards, ensuring reliability for military and aerospace environments.

Feature Summary

• Qualified for military and aerospace environments per MIL-PRF-19500/118 specifications
• Operates reliably across an extended junction temperature range from -65°C to +175°C
• Provides stable voltage regulation with tight tolerance in a hermetically sealed DO-35 package

Applications

• Military electronic systems requiring high-reliability voltage reference
• Aerospace instrumentation and control circuits
• Harsh environment power supply regulation

Procurement Notes

Verify that the specific order includes the correct military qualification suffix and package style. Confirm compliance with MIL-PRF-19500/118 requirements during procurement. Ensure storage and handling procedures meet moisture sensitivity guidelines for hermetic packages. Validate supplier authorization for defense-grade components prior to purchase.

Selection Notes

Select this component when strict environmental resilience and long-term stability are required. The DO-35 package suits through-hole mounting in compact assemblies. Consider the 10 V nominal voltage and 20 mA test current for circuit design compatibility. Evaluate thermal management needs given the wide operating temperature range.

Part Context

The 2N5264 belongs to Microchip's family of hermetically sealed Zener diodes intended for demanding applications. These devices are manufactured to meet rigorous military standards, offering superior performance compared to commercial equivalents. The series supports critical infrastructure where failure is not an option, providing consistent voltage regulation under extreme conditions.

Replacement Considerations

Substitute only with parts explicitly listed as equivalent in official Microchip documentation or cross-reference guides. Verify that any replacement meets the same MIL-PRF-19500/118 qualification level. Ensure pinout and mechanical dimensions match the DO-35 form factor.
