The HGT1S20N36G3VL is an N-Channel, logic level, voltage clamping Insulated Gate Bipolar Transistor (IGBT) manufactured by Fairchild Semiconductor. Designed primarily for automotive ignition coil driver applications, this device integrates a unique active voltage clamp between the collector and gate to enable Self Clamped Inductive Switching (SCIS). The component features internal diodes for electrostatic discharge (ESD) protection on the logic level gate, along with both series and shunt resistors within the gate circuit. It supports junction temperatures up to 175°C and is capable of handling ignition energy requirements.
Verify the manufacturer datasheet for exact electrical parameters such as collector-emitter saturation voltage and switching times. Confirm package type and pinout compatibility with existing PCB layouts. Ensure thermal management solutions support the specified maximum junction temperature of 175°C during operation.
Select this IGBT when designing automotive ignition systems requiring logic level gate drive capabilities. The integrated voltage clamp simplifies circuit design by eliminating external snubber components typically needed for inductive load switching. Consider the 14A current rating and 360V blocking voltage when matching system requirements.
This component belongs to Fairchild's family of voltage clamping IGBTs designed for robust inductive switching applications. Similar parts include the HGT1S14N36G3VL and HGTP20N35G3VL, which share the same SCIS functionality and logic level gate characteristics but may differ in specific current or voltage ratings.
Direct substitutes include the HGT1S14N36G3VL from Intersil/Fairchild and the HGTD7N60C3 from Harris Corporation. Verify that replacement devices maintain compatible logic level gate drive requirements and voltage clamping specifications for ignition coil applications.
