Overview
The Microchip Technology 1N4697-1 is a hermetically sealed, axial-leaded glass Zener diode in the DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 10 V with a standard tolerance of ±5%. The device operates within a junction temperature range of -65 °C to +175 °C and features a steady-state power dissipation rating of 0.5 W. Key electrical characteristics include a maximum reverse leakage current of 1 µA at 10 V and a Zener test current of 50 µA.
Feature Summary
- Hermetically sealed internal metallurgical bond construction
- Voltage regulation guaranteed across a broad operating current range
- Inherently radiation hard design
- Non-sensitive to electrostatic discharge
Applications
- Voltage regulation over broad operating current and temperature ranges
- Radiation-hardened electronic systems
- Military and aerospace circuit protection
Procurement Notes
Verify the specific suffix requirements for your application. The base part number indicates a commercial grade device. If RoHS compliance is required, confirm the availability of the e3 suffix variant. Ensure the metallurgical bond option (-1) matches your environmental specifications. Consult official documentation for screening options referencing MIL-PRF-19500 if higher reliability levels are needed.
Selection Notes
Select this component when a hermetically sealed, axial-leaded Zener diode is required for high-reliability applications. The 1N4697-1 offers a 10 V breakdown voltage suitable for precise reference circuits. Consider the tight voltage tolerances available via specific ordering suffixes if stricter regulation accuracy is necessary compared to standard commercial equivalents.
Part Context
This component belongs to the 1N4678-1 through 1N4717-1 series of 0.5 watt Zener voltage regulators manufactured by Microsemi (now Microchip Technology). The series covers a voltage selection from 1.8 to 43 volts. These devices are designed for demanding environments, offering flexible axial-lead mounting terminals and minimal capacitance characteristics.
Replacement Considerations
Equivalent parts include the 1N4697D-1 from Microsemi. Verify package compatibility and electrical parameter alignment before substitution.
