Overview
The Microchip Technology 1N6538 is a unidirectional silicon Zener diode designed for voltage regulation and transient protection. It features a DO-41 glass axial leaded package with a nominal Zener voltage of 36V and a power dissipation rating of 1.5W. The device exhibits a tolerance of 10% and is constructed with a glass passivated junction for enhanced reliability. It operates within a standard temperature range suitable for general-purpose electronic circuits requiring stable reference voltages or surge suppression.
Feature Summary
- Unidirectional voltage regulation capability
- Glass passivated junction construction
- DO-41 axial leaded package format
Applications
- General purpose voltage regulation
- Surge protection in low-power circuits
- Voltage reference applications
Procurement Notes
Verify the specific suffix code to confirm RoHS compliance status, as historical variants may differ. Ensure the DO-41 package dimensions match the target PCB footprint. Confirm the 10% voltage tolerance meets circuit requirements. Check for any military-grade equivalents if high-reliability standards are mandated by the design specification.
Selection Notes
Select this component when a 36V unidirectional Zener diode is required in an axial package. Compare against bidirectional TVS options if transient protection polarity is not fixed. Evaluate thermal derating curves for high ambient temperatures. Consider surface-mount alternatives if board space constraints exist.
Part Context
This part belongs to the standard Zener diode family used for basic voltage clamping. It serves as a cost-effective solution for low-power regulation tasks. The DO-41 package allows for through-hole mounting, facilitating easy integration into legacy designs and prototyping boards without requiring specialized surface-mount assembly equipment.
Replacement Considerations
Equivalent parts include other manufacturers' 36V 1.5W Zener diodes in the DO-41 package. Verify electrical parameters such as impedance and leakage current before substitution. Ensure the replacement maintains the same unidirectional characteristic and package compatibility.
