Overview
The Microchip Technology 1N4714-1 is a 0.5 W axial-leaded Zener voltage regulator in a hermetically sealed glass DO-35 (DO-204AH) package. It features an internal metallurgical bond and provides a nominal Zener voltage of 33 V with a standard 5% tolerance. The device operates within a junction temperature range of -65°C to +175°C, supports a maximum DC Zener current of 14.4 mA, and maintains a maximum reverse leakage current of 0.01 µA at the specified test conditions.
Feature Summary
- Internal metallurgical bond construction for high reliability
- Hermetically sealed glass DO-35 axial-lead package
- Wide operating temperature range from -65°C to +175°C
- Low capacitance characteristics
Applications
- Voltage regulation over broad operating current and temperature ranges
- Temperature compensated Zener reference applications
- Radiation-hardened circuit designs
Procurement Notes
Verify the specific suffix requirements for your application. The '-1' suffix indicates the internal metallurgical bond option. Confirm RoHS compliance status if required, as commercial versions may differ from military screening options. Check availability for MIL-PRF-19500 up-screening prefixes such as MQ or MX if higher reliability levels are needed.
Selection Notes
Select this component when a hermetically sealed, radiation-tolerant Zener diode is required. The 1N4714-1 offers a 33 V nominal breakdown with tight leakage specifications. Ensure the design accommodates the 0.5 W power dissipation limit and the thermal resistance characteristics of the DO-35 package under expected ambient conditions.
Part Context
This part belongs to the 1N4678-1 through 1N4717-1 series of 0.5 W Zener voltage regulators. The series covers nominal voltages from 1.8 V to 43 V. These devices are JEDEC registered and offer tighter voltage tolerances of 2% and 1% via additional suffixes like 'C' or 'D'.
Replacement Considerations
Equivalent parts include the 1N4714 without the '-1' suffix for non-bonded versions, or surface mount equivalents like the 1N4714UR-1 in the DO-213AA package. Verify pinout compatibility and thermal performance when substituting.
FAQ
What does the '-1' suffix indicate on the 1N4714-1?
The '-1' suffix denotes that the device features an internal metallurgical bond, similar to military requirements for improved reliability.
Is the 1N4714-1 sensitive to electrostatic discharge?
No, the device is not sensitive to ESD per MIL-STD-750 method 1020.
