STTH108A FAQs
1.Q: Are there related diodes with similar specs to the STTH108A?
A: STMicroelectronics offers variants like STTH1R06A (600V/1A) or STTH2R06A (600V/2A) for lower-voltage needs. Check datasheets for alternatives with matching trr/VF specs.
2.Q: What package does the STTH108A use, and is it surface-mountable?
A: The STTH108A comes in an SMA (DO-214AC) molded plastic package with 2 pins. It is surface-mountable (SM) and has a peak reflow tolerance of 260°C.
3.Q: Is the STTH108A compliant with industry certifications?
A: Yes, it is RoHS compliant and follows JESD-30/JESD-609 standards. However, it is marked as "not compliant" with REACH due to exemptions.
4.Q: What is the typical forward voltage (VF) of the STTH108A at 1A?
A: The STTH108A has a max forward voltage of 1.25V at 1A (typical value is lower; refer to the datasheet for detailed curves).
5.Q: What are the absolute maximum ratings for the STTH108A diode?
A: Absolute max ratings: Repetitive reverse voltage (VRRM): 800V, non-repetitive peak forward current (IFSM): 20A, operating temperature: up to 175°C. Exceeding these may damage the device.
6.Q: In what applications is the STTH108A commonly used?
A: Typical applications include SMPS (switch-mode power supplies), inverters, DC-DC converters, freewheeling/clamping circuits, and industrial power systems requiring high-voltage rectification.
7.Q: What are the key features of the STTH108A rectifier diode?
A: Key features include: 800V reverse voltage, 1A forward current, ultra-fast recovery (75ns), low forward voltage (1.25V max), SMA package, and RoHS compliance. It also supports free-wheeling and snubber applications.
8.Q: What is the pinout configuration of the STMicroelectronics STTH108A diode?
A: The STTH108A has a standard SMA package with 2 pins (C-bend terminals) in a DUAL configuration (JESD-30: R-PDSO-C2). Pin 1 is the anode, and pin 2 is the cathode.
