Overview
The DZ23C5V1-G3-18 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 5.1 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 2 μA at 4.85 V and a dynamic resistance of 60 Ω at 1 kHz. The component supports an operating temperature range from -55 °C to +150 °C.
Feature Summary
- Silicon planar construction for reliable small-signal regulation
- Graded Zener voltages according to international E24 standard
- Common cathode circuit configuration within dual-diode array
Applications
- Voltage reference circuits requiring stable low-voltage rails
- Clamping applications for signal protection
- Biasing networks in analog electronic designs
Procurement Notes
Verify the specific ordering code suffix against the manufacturer's documentation to confirm reel specifications. The '-18' suffix indicates units are supplied in reels of 10,000 on 8 mm tape. Confirm RoHS compliance status and material categorization details directly from the official datasheet before finalizing procurement orders.
Selection Notes
Select this component when a precise 5.1 V reference is needed in a compact SOT-23 footprint. Ensure the application current does not exceed the 5 mA test condition to maintain accuracy. Verify that the thermal dissipation requirements align with the 300 mW limit on standard FR-4 substrates rather than the higher absolute maximum rating.
Part Context
This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of graded voltages from 2.2 V to 75 V. The 'G3' designation signifies green commercial grade packaging compliant with environmental directives.
Replacement Considerations
Direct parameter-equivalent replacements within the same series include DZ23C5V1-E3-18 and DZ23C5V1-G3-08. These variants share identical electrical characteristics but differ in packaging quantities or lead-free processing history.
