Overview
The AZ23C5V1-E3-08 is a silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common anode configuration within a SOT-23 surface-mount package. The nominal Zener voltage is 5.1 V with a ±5% tolerance, tested at a current of 5 mA. Maximum power dissipation is rated at 300 mW on an FR-4 board and 500 mW with leads clamped. The device operates across a temperature range of -55°C to +150°C and complies with RoHS standards.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Silicon planar technology ensuring stable voltage regulation
- ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
- RoHS-compliant commercial grade construction
Applications
- Voltage reference circuits requiring dual regulated rails
- Transient voltage suppression in low-power applications
- Clamping circuits for signal lines
Procurement Notes
Verify the ordering suffix '-08' corresponds to the 3000-unit tape and reel packaging format. Confirm that the 'E3' designation indicates RoHS compliance without halogenated flame retardants. Ensure the component matches the specific 5.1 V Zener voltage requirement for the target application.
Selection Notes
Select this part when a dual common anode Zener array is required in a compact SOT-23 footprint. The 5.1 V nominal voltage and ±5% tolerance suit general-purpose regulation tasks. Consider thermal derating if ambient temperatures exceed standard operating ranges or if power dissipation approaches the 300 mW limit on FR-4 substrates.
Part Context
This component belongs to the AZ23 series of small signal Zener diodes from Vishay. The series offers various Zener voltages graded according to the E24 standard. The 'C' in the part number denotes the ±5% voltage tolerance, distinguishing it from the 'B' variant which provides ±2% tolerance.
Replacement Considerations
AZ23C5V1-E3-18: Identical electrical specifications but packaged in 10,000-unit reels instead of 3,000-unit reels.
