Product details

High-voltage fast-recovery diode in a dual ISOTOP package

The 115 ns reverse recovery time (trr) qualifies it as fast recovery (<= 500 ns, > 200 mA Io), making it suitable for high-frequency rectification in power converters, motor drives, and traction inverters where switching losses must be controlled. The ISOTOP package is designed for chassis mounting, providing direct thermal conduction to the heatsink for high-current operation at junction temperatures up to 150°C.

Obsolete — plan for last-time buy or replacement

STMicroelectronics lists the STTH6112TV2 as obsolete. For existing designs that require this exact diode, last-time-buy procurement through independent distribution is the available channel. Buyers should secure sufficient lifetime stock through an RFQ or evaluate a functionally equivalent high-voltage fast-recovery diode in the same package and voltage class.

1200 V blocking and 30 A conduction — what drives the selection

The 1200 V reverse voltage rating suits DC-link and output rectification in high-voltage systems. The 30 A average per diode supports continuous output currents.

Frequently asked questions

What is the exact replacement for STTH6112TV2?

No official replacement order code is listed by STMicroelectronics for the STTH6112TV2. For a replacement, look for a high-voltage fast-recovery diode in the ISOTOP package with 1200 V reverse voltage and at least 30 A per diode — the functional equivalent will need the same package and similar trr to maintain switching performance.

What is STTH6112TV2's reverse recovery time?

The STTH6112TV2 has a reverse recovery time of 115 ns, which places it in the fast-recovery category (<= 500 ns, > 200 mA Io). This trr is the key parameter for turn-off losses in hard-switched converters.
