UNISONIC TECHNOLOGIES CO., LTD Preliminary BYC8-600 DIODE ULTRAFAST, LOW SWITCHING LOSS RECTIFIER DIODE DESCRIPTION The UTC BYC8-600 is a rectifier diode. It provides the designers with ultra-fast switching and low switching loss in associated MOSFET. The UTC BYC8-600 is generally applied in continuous current mode(CCM), power factor correction (PFC), half-bridge lighting ballasts and half-bridge/full-bridge switched mode power supplies. FEATURES * Low Reverse Recovery Current * Ultra-Fast Switching * Low Switching Loss In Associated MOSFET * Low Thermal Resistance SYMBOL ORDERING INFORMATION Ordering Number Package Lead Free Plating Halogen Free BYC8L-600-TA2-T BYC8G-600-TA2-T TO-220-2 Note: Pin Assignment: A: Anode, K: Cathode, Tab: Mounting Base www.unisonic.com.tw Copyright © 2010 Unisonic Technologies Co., Ltd Pin Assignment 1 2 Tab K A K Packing Tube 1 of 3 QW-R601-025.b BYC8-600 DIODE Preliminary ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL RATINGS UNIT Peak Repetitive Reverse Voltage VRRM 600 V Crest Working Reverse Voltage VRWM 600 V square-wave pulse;δ =0.5; IF(AV) Average Forward Current 8 A TTab ≤109°C square-wave pulse; δ =0.5; IFRM Repetitive Peak Forward Current 16 A tP = 25µs, TTab ≤109°C tP=8.3ms,sine-wave 60 A pulse;TJ =150°C IFSM Non-Repetitive Peak Forward Current. tP=10ms,sine-wave 55 A pulse;TJ =150°C Operating Junction Temperature TJ 150 °C Storage Temperature TSTG -40 ~ +150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
