Overview
The BZX84C4V3TW_R1_00001 is a triple isolated surface mount Zener diode manufactured by Panjit International Inc. It operates within a voltage range of 2.4 to 75 Volts and features a power dissipation rating of 200 mWatt. The device utilizes an SOT-363 molded plastic case with terminals solderable per MIL-STD-750, Method 2026. For the specific 4.3V variant, the nominal Zener voltage is 4.3V (min 4.09V, max 4.52V), with a maximum Zener impedance of 90 Ohms at 5.0 mA test current and a maximum reverse leakage current of 3.0 uA at 1.0V. The component supports operating junction and storage temperatures ranging from -65°C to +150°C.
Feature Summary
- Triple isolated configuration for independent circuit operation
- Compliant with EU RoHS2.0 directive and IEC61249 halogen-free standards
- Designed for automatic insertion processes
Applications
- Voltage regulation in low-power electronic circuits
- Reference voltage generation in signal processing applications
- Overvoltage protection in consumer electronics
Procurement Notes
Verify the ordering suffix against official documentation to confirm packing type and size specifications. Ensure compliance with environmental directives such as RoHS2.0 and halogen-free requirements before procurement. Confirm thermal resistance parameters relative to minimum pad mounting on FR-5 boards for accurate thermal management planning.
Selection Notes
Select this component based on the required nominal Zener voltage and maximum power dissipation limits. Evaluate the maximum Zener impedance and reverse leakage current specifications against circuit sensitivity requirements. Verify that the SOT-363 package dimensions align with the available PCB footprint and mounting pad layout constraints.
Part Context
This part belongs to the BZX84C2V4TW~BZX84C75TW series of triple isolated surface mount Zener diodes. The series covers a wide voltage range from 2.4V to 75V, providing standardized options for various reference and regulation needs. The R1 suffix indicates a specific tape and reel packing configuration.
Replacement Considerations
Direct replacements must match the triple isolated configuration, SOT-363 package, and 200mW power rating. Verify electrical characteristics including Zener voltage tolerance, impedance, and leakage current to ensure circuit compatibility.
