The HGTP20N35G3VL is a 20A, 350V N-Channel IGBT manufactured by Fairchild Semiconductor. It is a logic level device designed for automotive ignition coil drivers. Key electrical parameters include a collector-emitter saturation voltage of 1.8V at 20A and a gate-emitter threshold voltage range of 2.0V to 4.0V. The component features an internal active voltage clamp providing Self Clamped Inductive Switching (SCIS) capability. It operates with a maximum junction temperature of 175°C and includes internal diodes for ESD protection on the gate.
Verify the specific suffix G3VL against the official datasheet to confirm package type and compliance status. Ensure the source document explicitly identifies Fairchild Semiconductor as the manufacturer rather than a distributor hosting the file. Confirm RoHS compliance details if required for the target assembly process.
Select this component when designing automotive ignition systems requiring logic level drive compatibility without external gate resistors. The integrated voltage clamp simplifies circuit design by handling inductive kickback. Verify that the 350V breakdown voltage meets the specific ignition coil requirements of the application.
This part belongs to the family of logic level, voltage clamping IGBTs intended for automotive applications. Similar variants include the HGTP20N35G3VLS and HGT1S14N36G3VL, which share the SCIS feature set but may differ in current ratings or voltage thresholds. These devices are distinct from standard high-voltage IGBTs due to their specialized gate protection and drive characteristics.
Potential substitutes include the HGTP20N35G3VLS and HGT1S14N36G3VL. Verify pinout compatibility and ensure the replacement maintains the same logic level gate drive requirements and SCIS functionality before integration.
