UNISONIC TECHNOLOGIES CO., LTD BYC20 DIODE Preliminary RECTIFIER DIODE, HYPERFAST DESCRIPTION The UTC BYC20 is a rectifier diode. It provides the designers with ultra-fast switching and low switching loss in associated MOSFET. The UTC BYC20 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 Halogen Free BYC20L-TA2-T BYC20G-TA2-T TO-220-2 Note: Pin Assignment: A: Anode K: Cathode Tab: Mounting Base Pin Assignment 1 2 Tab K A K Packing Tube MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 3 QW-R601-027.c BYC20 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 250 A Non-Repetitive Peak Forward tP=10ms,sine-wave pulse; 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.
