Overview
The DZ23C39-E3-08 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 39 V with a standard tolerance of ±5 %. The device operates at a test current of 2 mA and features a maximum reverse leakage current of 50 µA at 29 V. Dynamic resistance is specified at 87 Ω (ZZ) and 300 Ω (ZZK). It supports a power dissipation of up to 500 mW and functions within a temperature range of -55 °C to +150 °C.
Feature Summary
- Utilizes silicon planar technology for stable voltage regulation
- Complies with international E24 standard grading for voltage values
- Offers high electrostatic discharge protection capability
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in electronic systems
- Clamping applications for signal lines
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number against official Vishay documentation. Confirm that the ordering suffix matches the required tape-and-reel specifications. Ensure compliance with RoHS directives and material categorization standards before finalizing procurement orders.
Selection Notes
Select this component when a 39 V Zener voltage is required in a compact SOT-23 footprint. Consider the 2 mA test current and specific dynamic resistance values for circuit accuracy. Evaluate thermal management requirements based on the 500 mW power dissipation limit and ambient operating conditions.
Part Context
This component belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V, all graded according to the E24 standard. The base P/N-E3 designation indicates a RoHS-compliant commercial grade product packaged in taped units.
Replacement Considerations
Direct substitutes include other DZ23 series variants with identical packaging but different voltage ratings, such as DZ23C36-E3-08 or DZ23C43-E3-08. Cross-manufacturer equivalents must be verified for matching pinout, voltage tolerance, and thermal characteristics.
FAQ
What is the dynamic resistance specification for the DZ23C39-E3-08?
The dynamic resistance is specified as 87 Ω at the test current IZT1 and 300 Ω at IZT2.
Does the DZ23C39-E3-08 have AEC-Q101 qualification?
No, the base P/N-E3 version is a commercial grade product. AEC-Q101 qualification is available only for the HE3_A variant.
