Overview
The Microchip Technology 1N4754CP/TR8 is a silicon 1-watt Zener diode in the 1N4728AP to 1N4764AP series. It provides voltage regulation at a nominal Zener voltage of 39 V with a tight tolerance of +/- 2%, indicated by the 'C' suffix. The device operates within an ambient temperature range of -65°C to +150°C and features a plastic DO-41 (DO-204AL) axial-lead package. Electrical characteristics include a maximum dynamic impedance of 60 Ohms at a test current of 6.5 mA, a maximum reverse current of 5 µA at 23 V, and a maximum regulator current of 115 mA.
Feature Summary
- Provides precise voltage regulation with a tight +/- 2% tolerance on the nominal Zener voltage.
- Features a void-free transfer molded thermosetting epoxy body that meets UL94V-0 flammability standards.
- Offers flexible axial-lead mounting terminals suitable for through-hole applications.
- Moisture classified as Level 1 per IPC/JEDEC J-STD-020B, requiring no dry pack.
Applications
- Voltage regulation over broad operating current and temperature ranges
- Reference voltage sources in electronic circuits
- Overvoltage protection components
Procurement Notes
Verify the specific ordering suffixes against official documentation to confirm exact electrical tolerances and packaging configurations. Confirm RoHS compliance status if required, as standard versions may differ from e3 variants. Ensure the TR suffix matches the intended reel quantity and tape specifications for automated assembly processes.
Selection Notes
Select this component when a stable 39 V reference with high precision is required. The C suffix ensures tighter voltage accuracy compared to standard A or un-suffixed parts. Consider the 1 W power dissipation rating and thermal resistance values for heat management in the final design.
Part Context
This part belongs to the widely used 1N47xx series of JEDEC registered Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a voltage selection from 3.3 to 100 volts. The 'P' suffix denotes the plastic encapsulated construction, which offers lower thermal resistance compared to glass-body options.
Replacement Considerations
Equivalent plastic packages are available within the same series, such as the 1N4754AP for 5% tolerance or 1N4754DP for 1% tolerance. Surface mount equivalents like the SMAJ4754A or MLL4754A provide functional alternatives for different mounting styles.
