Overview
The AZ23B5V1-E3-08 is a dual common anode silicon planar Zener diode array manufactured by Vishay Semiconductors. It features a nominal Zener voltage of 5.1 V with a tight tolerance of ±2%. The device operates within a test current range of 2 to 5 mA and provides a maximum reverse leakage current of 1 µA at 5 V. Dynamic resistance is specified at 60 Ω, with a temperature coefficient between -3 and 4 x 10⁻⁴/°C. Packaged in a compact SOT-23 housing, it supports power dissipation up to 500 mW and functions reliably across an operating temperature range of -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- Tight ±2% voltage tolerance for precision regulation applications
- ESD protection capability exceeding 8 kV via human body model
- RoHS-compliant commercial grade construction
Applications
- Precision voltage reference circuits requiring dual rails
- Overvoltage protection stages in signal conditioning paths
- Clamping networks for sensitive input interfaces
Procurement Notes
Verify the specific ordering code suffix against project requirements to ensure correct packaging format and quantity constraints. Confirm that the standard commercial grade meets environmental specifications for the intended deployment location. Cross-reference the RoHS compliance status with regulatory mandates applicable to the final assembly region before initiating procurement actions.
Selection Notes
Select this component when dual independent Zener references are required within a single footprint. The ±2% tolerance distinguishes it from standard ±5% variants. Ensure the application current remains within the 2 mA to 5 mA test range to maintain accuracy. Verify thermal management capabilities if ambient temperatures approach the upper operational limit of 150 °C.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes. The 'B' designation indicates the tighter ±2% voltage tolerance compared to the 'C' series. The '-E3' suffix denotes lead-free termination compliant with RoHS standards. The '-08' suffix specifies the standard 3000-unit reel packaging format on an 8 mm tape.
Replacement Considerations
AZ23B5V1-E3-18 (Same electrical specs, different 10000-unit reel packaging)
FAQ
What is the marking code for the AZ23B5V1?
The marking code for the AZ23B5V1 is DD8.
Does the AZ23B5V1-E3-08 have AEC-Q101 automotive qualification?
No, the base P/N-E3 is commercial grade. Automotive qualification requires the HE3_A suffix.
What is the maximum reverse leakage current at 5 V?
The maximum reverse leakage current is 1 µA at a reverse voltage of 5 V.
