Overview
The DZ23C51-7-F is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It features two Zener diodes in a common cathode configuration within an SOT-23 package. The nominal Zener voltage is 51 V with a tolerance range of 48 V to 54 V at a test current (IZT) of 5.0 mA. Maximum Zener impedance is 100 Ω at IZT and 750 Ω at IZK of 1.0 mA. The device supports a maximum power dissipation of 300 mW and operates within a temperature range of -65°C to +150°C.
Feature Summary
- Dual Zener diodes integrated in a single common cathode configuration for space-efficient designs.
- High reliability qualification meeting JEDEC standards for demanding applications.
- Environmentally compliant construction that is lead-free, halogen-free, and antimony-free.
Applications
- Voltage reference circuits requiring stable dual supply rails.
- Transient voltage suppression in low-power signal lines.
- Clamping applications in general-purpose electronic equipment.
Procurement Notes
Verify the specific ordering suffix '-7-F' corresponds to commercial grade qualification and tape & reel packaging. Confirm the manufacturer source directly from Diodes Incorporated or authorized distributors to ensure component authenticity and traceability.
Selection Notes
Select this part when a dual Zener solution is required in a compact SOT-23 footprint. Ensure the 51 V breakdown voltage aligns with circuit requirements and verify that the 300 mW power dissipation rating accommodates the thermal environment of the final assembly.
Part Context
This component belongs to the DZ23C series of dual surface mount Zener diodes. The series offers various voltage options ranging from 2.7 V to 51 V, all sharing the same 300 mW power rating and SOT-23 mechanical outline for standardized board layout compatibility.
Replacement Considerations
Check for automotive qualified equivalents with the Q-suffix if AEC-Q100/101 compliance is required. Verify pinout compatibility with other SOT-23 dual Zener arrays before substitution.
FAQ
What is the typical temperature coefficient for the DZ23C51-7-F?
The typical temperature coefficient is +0.110 %/°C.
Is there a minimum reverse voltage specification for this device?
Yes, the datasheet specifies a minimum reverse voltage of 38 V at a reverse current of 0.1 µA.
Does the 'F' suffix indicate a functional change?
No, the '-7-F' suffix indicates commercial qualification and tape & reel shipping format; it does not alter the electrical characteristics.
