Overview
The DZ23C8V2-E3-18 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 8.2 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 0.1 µA at 6 V. Dynamic resistance is specified at 7 Ω (at Izt) and 50 Ω (at Izk). It supports a power dissipation of up to 500 mW and functions within a temperature range of -55 °C to +150 °C.
Feature Summary
- Silicon planar construction for reliable voltage regulation
- ESD protection exceeding 8 kV via human body model and 800 V via machine model
- RoHS-compliant commercial grade material categorization
Applications
- Voltage reference circuits requiring stable low-voltage rails
- Clamping applications for transient voltage suppression
- General-purpose signal conditioning in consumer electronics
Procurement Notes
Verify the specific ordering code suffix against project requirements. The '-18' designation indicates a standard 10,000-unit reel on a 13-inch tape. Confirm that the commercial grade specification meets environmental standards for the intended deployment environment before finalizing procurement orders.
Selection Notes
Select this component when a precise 8.2 V reference is needed in a compact SOT-23 footprint. Ensure the circuit design accommodates the 5 mA test current requirement for accurate voltage regulation. Verify that the thermal management strategy aligns with the 500 mW absolute maximum rating under expected operating conditions.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series covers a wide voltage range from 2.2 V to 75 V, utilizing standardized E24 grading. The DZ23C8V2 variant specifically targets the 8.2 V segment of this portfolio.
Replacement Considerations
Direct substitutes include other manufacturers offering 8.2 V Zener diodes in SOT-23 packages with matching ±5 % tolerance and similar dynamic resistance characteristics. Cross-referencing electrical parameters such as leakage current and thermal resistance is essential for equivalent performance.
FAQ
