Overview
The Microchip Technology 1N4735CP/TR12 is a silicon 1.0-watt Zener diode in the 1N4728AP to 1N4764AP series, housed in a plastic DO-41 (DO-204AL) axial-lead package. It provides voltage regulation with a nominal Zener voltage of 6.2 V and a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 2 Ohms at a test current of 41 mA. It is supplied in tape and reel packaging.
Feature Summary
- Provides precise voltage regulation with a ±2% tolerance on nominal Zener voltage
- Features flexible axial-lead mounting terminals for through-hole applications
- Constructed with a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards
- Moisture classified as Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack
Applications
- Voltage regulation over broad operating current and temperature ranges
- General purpose circuit protection and reference voltage generation
- Power supply output stabilization
Procurement Notes
Verify that the specific part number matches the required tolerance and packaging configuration. Confirm the manufacturer origin, as this component originates from the Microsemi Scottsdale Division, now part of Microchip Technology. Ensure the ordering suffix aligns with the desired lead type and reel specifications before finalizing procurement orders.
Selection Notes
Select this component when a 6.2 V reference with tighter than standard 5% tolerance is required. The plastic construction offers lower thermal resistance compared to glass-body options. Consider the 1.0 W power dissipation rating and ensure adequate heat sinking or board layout compliance for steady-state operation above 105°C lead temperature.
Part Context
This component belongs to the popular 1N4728A through 1N4764A series of 1.0 watt Zener diodes. The series covers an extensive voltage selection from 3.3 to 100 volts. While standard versions carry a 5% tolerance, variants with specific suffixes provide tighter tolerances for precision applications.
Replacement Considerations
Surface mount equivalents are available as SMAJ4735A or MLL4735A. For military screening levels, prefixes such as MQ, MX, MV, or MSP may be added to the base part number.
