Frequently Asked Questions
What are the key electrical ratings of the STTH1212D?
The STTH1212D is rated for 12A maximum forward current, 1200V maximum reverse voltage, a 100ns reverse recovery time, and 1.9V maximum forward voltage (VF). These specifications make it suitable for high-voltage ultrafast rectification in demanding power electronics applications.
What package does the STTH1212D come in?
The STTH1212D is available in a 2-pin TO-220AC through-hole package (JEDEC-95 Code: TO-220AC, JESD-30 Code: R-PSFM-T2). This package provides good thermal performance and is widely used in power discrete components for easy heatsink attachment and PCB mounting.
What applications is the STTH1212D suited for?
The STTH1212D is specifically designed for high-voltage ultrafast soft-recovery applications, including use as a freewheeling diode in motor drive inverters, snubber diode in switch-mode power supplies, and output rectifier in PFC boost converters operating at high switching frequencies up to 1200V.
What makes the STTH1212D a soft-recovery diode?
The STTH1212D uses a soft-recovery rectifier design that reduces the rate of change (di/dt) during reverse recovery, minimizing voltage spikes and electromagnetic interference (EMI) in switching power circuits. This property is critical for reducing stress on switching transistors and improving system reliability.
What is the factory lead time for the STTH1212D?
The STTH1212D has a factory lead time of approximately 15 weeks. Buyers planning large production volumes should account for this lead time when ordering, or check distributor stock for faster availability from existing inventory.
