Overview
The 1N4737AP-TP is a single Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 7.5 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and utilizes the DO-41 axial through-hole package. Key electrical characteristics include a maximum reverse leakage current of 10 µA at 5 V, a forward voltage of 1.2 V at 200 mA, and a maximum Zener impedance of 4 Ohms. The component operates within a temperature range of -65°C to 150°C.
Feature Summary
- Hermetically sealed glass construction for environmental protection
- Planar silicon die technology for stable regulation
- Lead-free finish compliant with RoHS standards
Applications
- Voltage reference circuits
- Overvoltage protection
- Clipper and clamper circuits
Procurement Notes
Verify the specific suffix 'TP' against the manufacturer's latest datasheet to confirm lead-free status and compliance details. Confirm the package type matches the required DO-41 form factor. Check for any recent Product Change Notifications regarding packaging or material updates. Ensure the ±5% tolerance meets the circuit requirements. Validate availability status as supply conditions may vary.
Selection Notes
Select this component when a standard 7.5 V regulation point is required in an axial leaded format. The 1 W power rating supports moderate current applications. The low dynamic impedance of 4 Ohms ensures effective noise filtering. Verify that the operating temperature range covers the intended environment. Consider the physical size constraints of the DO-41 package during layout.
Part Context
This part belongs to the 1N4737 series of 1-watt Zener diodes produced by MCC. The series offers a wide range of voltage options within the same mechanical footprint. The 'AP' designation typically indicates the axial leaded configuration. This family is designed for general-purpose voltage regulation tasks in industrial and consumer electronics.
Replacement Considerations
Cross-reference with other manufacturers offering JEDEC registered 1N4737 equivalents. Verify pinout compatibility and thermal characteristics. Ensure substitute parts meet the same ±5% voltage tolerance and 1 W power dissipation ratings.
