1、 Product Overview
DW52C2V7LED02 is an ultra small surface mount Zener diode launched by Jiangsu Changdian Technology (JCET), using advanced WBFBP02C packaging (size only 1.0 × 0.6 × 0.5 mm), optimized for high-density PCB design and portable electronic devices. Its core function is to achieve precise voltage stability through avalanche breakdown effect, with a nominal voltage stabilization value (VZ) of 2.7V and a working range of 2.5V-2.9V, suitable for scenarios with strict requirements for space and voltage accuracy.   

2、 Core Features and Technical Parameters
1. Electrical performance
Voltage stabilization accuracy: Under the condition of a test current (IZT) of 5mA, the voltage stabilization value is strictly controlled between 2.5V (Min) and 2.9V (Max), with a temperature coefficient as low as 3.5mV/° C, ensuring stability over a wide temperature range.   
Dynamic characteristics: Zener impedance (ZZT) with a typical value of 600 Ω, reverse leakage current (IR) ≤ 20 μ A (VR=1.0V), combining low power consumption and fast response capability.   
Reliability guarantee: power consumption of 100mW, thermal resistance of 1250 ℃/W, operating temperature coverage of 65 ° C to+150 ° C, suitable for industrial and automotive grade environmental requirements.   

2. Packaging advantages
The WBFBP02C package adopts a leadless surface mount design, supports 260 ℃ reflow soldering process, and is compatible with automated mounting equipment. Its miniaturized structure (with a thickness of only 0.5mm) significantly saves circuit board space and is suitable for compact products such as microsensors and wearable devices.   

3、 Typical application scenarios
Consumer Electronics: Used for power management circuits in devices such as mobile phones and TWS earphones to prevent voltage fluctuations from damaging ICs.
Industrial control: provides stable voltage reference for PLC modules and sensors, and resists electrical noise in industrial environments.   
Automotive Electronics: Protect the low-voltage signal path of the in car entertainment system and ECU unit to meet the reliability requirements of AECQ101.   
Precision instruments: low-power voltage stabilizing circuits in medical equipment to ensure measurement accuracy.   

4、 Manufacturer's Strength Background
