Panjit Products

Panjit offers four main product categories: (1) Schottky Diodes - Low forward voltage drop rectifiers ideal for high-efficiency power supplies, DC-DC converters, and freewheeling applications with voltage ratings from 20V to 200V; (2) Fast Recovery Diodes - Ultra-fast switching rectifiers designed for high-frequency applications including SMPS, inverters, and welding equipment with reverse recovery times from 25ns to 100ns; (3) Bridge Rectifiers - Full-wave rectification modules for AC-DC power conversion in industrial and consumer applications with current ratings from 0.5A to 50A; (4) Protection Devices - TVS diodes and transient voltage suppressors for circuit protection against ESD and surge events with power ratings from 400W to 5000W.

Browse our product categories below to find the specific Panjit devices for your application, or contact our FAE team for personalized selection assistance based on your requirements.

Selecting the right Panjit diode involves several key considerations: (1) Voltage rating - choose reverse voltage (VRRM) at least 1.5-2x your maximum operating voltage to ensure reliable operation under transient conditions; (2) Current rating - select average forward current (IF(AV)) based on load requirements with 30-50% margin for temperature derating; (3) Switching speed - use Schottky diodes for high-frequency applications above 100kHz due to negligible reverse recovery, fast recovery diodes for medium frequency 20-100kHz, and standard rectifiers for line frequency applications; (4) Forward voltage - lower VF means better efficiency, critical for battery-powered and low-voltage applications; (5) Package selection - consider thermal requirements and PCB space constraints, with SMA/SMB for compact designs and TO-220/TO-247 for high power applications.

Use the parameter tables in each category page to compare specifications, or contact our FAE team for personalized selection recommendations based on your specific voltage, current, and switching frequency requirements.

Schottky and Fast Recovery diodes serve different application needs based on their fundamental construction: Schottky diodes use metal-semiconductor junction providing several advantages: (1) Lower forward voltage drop (0.3-0.5V vs 0.8-1.2V) resulting in better efficiency and reduced heat generation; (2) Faster switching with negligible reverse recovery time, making them ideal for high-frequency applications above 100kHz; (3) Lower switching losses which reduces EMI and simplifies filter design; (4) Trade-off is higher leakage current and limited voltage rating typically below 200V. Fast Recovery diodes use PN junction with optimized lifetime control: (1) Higher voltage ratings up to 1200V suitable for high-voltage power supplies; (2) Lower leakage current providing better high-temperature performance; (3) Reverse recovery time of 25-100ns suitable for medium frequency switching; (4) Better high-temperature reliability for industrial applications.

For high-frequency, low-voltage applications below 100V, choose Schottky diodes. For high-voltage power supplies above 100V, choose Fast Recovery diodes. Contact us if you need help determining the best technology for your specific design.

Panjit offers diodes in various packages to meet different application requirements: (1) Surface Mount (SMD) packages including SMA (DO-214AC) for 1-2A applications with compact size for space-constrained designs, SMB (DO-214AA) for 2-5A applications offering good balance of size and thermal performance, and SMC (DO-214AB) for 3-8A applications with better thermal capability; (2) Through-Hole packages including DO-41 for 1-3A applications suitable for prototyping, DO-15 for 2-4A applications, and DO-201AD for 3-6A high-reliability applications; (3) Power Packages including TO-220AC/AB for 10-30A high-power applications requiring heat sinking, and TO-247 for highest power 30A+ applications; (4) Bridge Rectifier packages including GBU and GBJ for through-hole mounting, and KBPC for chassis mount with threaded stud. All packages are RoHS compliant and available in tape-and-reel for automated production.
