UNISONIC TECHNOLOGIES CO., LTD Preliminary BYC20-600 DIODE RECTIFIER DIODE, HYPERFAST DESCRIPTION The UTC BYC20-600 is a rectifier diode. It provides the designers with ultra-fast switching and low switching loss in associated MOSFET. The UTC BYC20-600 is ideally used in half-bridge lighting ballasts, half-bridge/full-bridge switched mode power supplies and continuous current mode (CCM) power factor correction (PFC). 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 BYC20L-600-TA2-T BYC20G-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-R601-027.b BYC20-600 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 =1.0; VR Reverse Voltage 500 V TTab ≤100°C square-wave pulse; δ =0.5; IF(AV) Average Forward Current 20 A TTab ≤93°C Repetitive Peak Forward square-wave pulse; δ =0.5; IFRM 40 A Current tP = 25µs, TTab ≤93°C Non-Repetitive Peak Forward tP=10ms,sine-wave pulse; 250 A IFSM Current tP=8.3ms,sine-wave pulse; 274 A 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.
