Overview
The AZ23B13-E3-08 is a silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common anode configuration housed in a SOT-23 surface-mount package. The nominal Zener voltage is 13 V with a tight tolerance of ±2%. Electrical characteristics include a maximum reverse leakage current of 0.1 µA at 10 V and a dynamic resistance of 25 Ω at the test current of 5 mA. The device operates within a temperature range of -55 °C to +150 °C and is RoHS compliant.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Tight ±2% Zener voltage tolerance for precision applications
- ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
- RoHS-compliant commercial grade construction
Applications
- Voltage reference circuits requiring stable dual supplies
- Overvoltage protection for sensitive signal lines
- Clamping applications in communication equipment
Procurement Notes
Verify the specific ordering code suffix against project requirements, as packaging quantities vary between 3000 units on 7-inch reels and 10000 units on 13-inch reels. Confirm that the commercial grade designation meets environmental standards for the intended deployment location before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener array with high voltage accuracy is required in a compact footprint. The ±2% tolerance distinguishes it from standard ±5% variants. Ensure the thermal dissipation limits on FR-4 boards are respected during layout to maintain reliability under continuous operation conditions.
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 confirms RoHS compliance, while '-08' specifies the 3000-unit tape and reel packaging format suitable for automated assembly processes.
