Key Features
- Ultra-low 0.46 V maximum forward voltage drop minimizes conduction losses for high-efficiency rectification in DC-DC converters and power supplies
- Single Schottky silicon rectifier in TO-220AC (R-PSFM-T2) vertical package with cathode case connection for simple heatsink mounting
- General-purpose 15 V rectifier diode introduced 2018 with excellent reverse recovery for high-frequency switching applications
Applications
The VS-19TQ015-M3 is suited for freewheeling diodes in DC-DC switching converters, polarity protection circuits, and low-dropout rectifier stages in 12 V and 15 V power supplies where the 0.46 V forward voltage drop significantly reduces conduction losses versus standard silicon rectifiers. Its TO-220AC through-hole package with cathode-to-case connection enables direct heatsink attachment for thermal management in motor drives, solar energy converters, and industrial power modules.

Frequently Asked Questions
What forward voltage and reverse voltage ratings does the VS-19TQ015-M3 provide?
The VS-19TQ015-M3 has a maximum forward voltage drop of 0.46 V and a reverse voltage rating of 15 V. The low 0.46 V forward voltage is a key advantage over standard silicon PN rectifiers that typically drop 0.7 V to 1.0 V, directly reducing power dissipation in high-current rectification stages.
How does the TO-220AC package of VS-19TQ015-M3 facilitate thermal management in power supply designs?
The TO-220AC vertical package (JEDEC-95) provides a metal tab with cathode case connection, allowing direct bolted attachment to a heatsink or chassis. This enables efficient heat dissipation for continuous forward currents well above 1 A, making the VS-19TQ015-M3 practical in power supply output rectifier stages that operate at elevated ambient temperatures up to 150°C junction.
For which DC-DC converter topologies is VS-19TQ015-M3 used as a freewheeling diode?
The VS-19TQ015-M3 is used as a freewheeling or catch diode in buck and boost converters operating at up to 15 V output. Its Schottky construction with a sub-microsecond reverse recovery time and 0.46 V forward voltage makes it effective in synchronous rectifier bypass and snubber-less designs at switching frequencies from 100 kHz to 1 MHz.
When should VS-19TQ015-M3 be preferred over a standard 1N5819 Schottky diode?
The VS-19TQ015-M3 in TO-220AC offers higher continuous current handling and a lower thermal resistance than the 1N5819 in DO-41 package. For designs drawing more than 1 A continuous current where 15 V reverse voltage is sufficient, the VS-19TQ015-M3 provides better thermal performance and lower junction temperature at the same power dissipation.
