Key Features
- 100 V reverse blocking voltage with 8 A forward current rating enabling robust rectification in mid-power switching and motor drive circuits
- Low maximum forward voltage of 0.88 V reducing conduction losses and improving efficiency in DC-DC converter output stages
- TO-263AB (D2PAK) surface-mount package with cathode case connection providing excellent thermal dissipation directly to PCB copper pours
Applications
The VS-8TQ100SHM3 is optimized for use as a freewheeling or catch diode in inductive motor drive circuits, synchronous buck converters, and flyback power supply output stages operating up to 100 V, where its low 0.88 V forward drop minimizes switching losses at 8 A continuous current. The TO-263AB (D2PAK) footprint allows direct thermal coupling to the PCB ground plane, supporting junction temperatures up to 175°C without an additional heatsink in many applications. It also serves general-purpose bridge rectification in industrial power supplies, solar charge controllers, and 48 V telecom power systems.

Frequently Asked Questions
What forward voltage and current ratings make VS-8TQ100SHM3 suitable for a 48 V freewheeling diode application?
The VS-8TQ100SHM3 is rated for 8 A continuous forward current with a maximum forward voltage of 0.88 V at rated current, plus a 100 V reverse blocking voltage that provides adequate margin above a 48 V rail. This combination limits conduction power loss to under 7 W at full load, making it efficient as a freewheeling diode in 48 V DC motor drive and power supply designs.
How does the TO-263AB (D2PAK) package of VS-8TQ100SHM3 assist thermal management on a PCB?
The TO-263AB (D2PAK) package includes a large exposed metal tab that acts as the cathode terminal bonded directly to the PCB copper, providing a thermal resistance junction-to-case (RθJC) typically around 2°C/W. With a maximum junction temperature of 175°C and ambient designs up to 85°C, the exposed pad allows the diode to dissipate several watts through PCB copper spreading without requiring a separate clip-on heatsink.
When is VS-8TQ100SHM3 a cost-effective replacement for the VS-10TQ100SHM3 in a 6 A output rectifier circuit?
In applications where peak output current stays below 8 A, the VS-8TQ100SHM3 is a drop-in substitute for the VS-10TQ100SHM3 since both share the same 100 V rating, TO-263AB footprint, and cathode-case configuration. The 8 A variant typically carries a lower unit price and shorter lead time of 8 weeks compared to higher-current variants, making it the preferred choice when the 10 A headroom of the VS-10TQ100SHM3 is unnecessary.
