The low Qg and Ciss make this device suitable for moderate-speed switching in flyback converters and auxiliary power supplies. The gate threshold voltage is 5 V maximum at 100 µA drain current, with a recommended drive voltage of 10 V for minimum on-resistance. The gate-source rating is ±30 V, giving headroom for overshoot in hard-switched topologies. ## Active production — sourcing and compliance posture The operating junction temperature range spans -55 °C to +150 °C, covering industrial and some automotive under-hood environments.","metaTitle":"STD4N90K5 MOSFET N-Ch 900V 3A DPAK STMicro MDmesh","metaDescription":"STD4N90K5 N-channel 900 V, 3 A MOSFET in DPAK.
