Overview
The BZX84C18TW_R1_00001 is a triple isolated surface mount Zener diode manufactured by Panjit International Inc. It operates within the BZX84C2V4TW to BZX84C75TW series, featuring a nominal Zener voltage of 18 V with a tolerance range of 17.10 V to 18.90 V. The device dissipates 200 mW and utilizes an SOT-363 molded plastic case. Electrical characteristics include a maximum Zener impedance (ZZT) of 45 Ω at a test current of 5.0 mA, and a maximum reverse leakage current of 0.1 µA at 12.6 V. The component supports an operating junction temperature range from -65 °C to +150 °C.
Feature Summary
- Triple isolated internal structure for independent circuit operation
- Halogen-free green molding compound compliant with IEC61249 standards
- Designed for automatic insertion in surface mount assembly processes
Applications
- Voltage regulation in multi-channel electronic circuits
- Reference voltage generation for precision measurement systems
- Over-voltage protection in signal processing paths
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging orientation and reel dimensions. Confirm RoHS compliance status and halogen-free material declarations match project requirements before procurement. Ensure the manufacturer's datasheet revision matches the production lot specifications.
Selection Notes
Select this component when three independent voltage references are required within a single compact footprint. The SOT-363 package accommodates high-density board layouts. Verify that the thermal resistance of 625 °C/W aligns with the available board space and copper pad area for adequate heat dissipation during continuous operation.
Part Context
This part belongs to the BZX84C TW series of triple isolated Zener diodes produced by Panjit International Inc. The series covers a wide voltage range from 2.4 V to 75 V. The R1 suffix indicates Tape and Reel packing on a 7-inch reel, distinguishing it from bulk or tube configurations.
Replacement Considerations
Direct replacements must maintain the triple isolated configuration and SOT-363 package. Verify that substitute components offer equivalent electrical parameters, specifically matching the 18 V nominal voltage and 200 mW power rating.
