Overview
The Microchip Technology 1N5523DE3/TR is a single silicon Zener diode housed in the DO-204AH (DO-35) through-hole package. It provides a nominal Zener voltage of 5.1 V with a tolerance of ±5%. The device operates at a test current of 5 mA and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 2 µA, a dynamic impedance of 26 Ohms, and a forward voltage of 1.1 V. It supports an operating temperature range from -65 °C to +175 °C and is supplied in a reel.
Feature Summary
- Provides stable voltage regulation via Zener breakdown mechanism
- Features hermetically sealed glass construction for environmental protection
- Supports high-temperature operation up to 175 °C
Applications
- Voltage reference circuits
- Overvoltage protection
- Clipping and clamping applications
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging rather than bulk units. Confirm RoHS compliance status as indicated by the 'E3' designation. Ensure the DO-204AH package dimensions match the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when a precise 5.1 V reference is required in a through-hole configuration. Consider the 26 Ohm dynamic impedance for noise-sensitive designs. Evaluate the 500 mW power dissipation limit against expected thermal conditions to ensure reliable long-term operation within the specified temperature range.
Part Context
This part belongs to the standard 1N5523 series of low-power Zener diodes manufactured by Microchip Technology. It serves as a lead-free compliant alternative to older non-compliant variants, maintaining identical electrical performance while adhering to modern environmental standards for semiconductor components.
Replacement Considerations
The 1N5523BUR-1 is a surface-mount equivalent in the DO-213AA-2 package. Direct pin-to-pin replacement is not possible due to the package difference; redesign of the PCB layout is required for SMT integration.
