Product details
Overview
STTH120L06TV1 from STMicroelectronics is a dual 600 V ultrafast high-voltage rectifier diode in ISOTOP package, rated for 60 A average forward current per diode and 70 ns maximum reverse recovery time, with 0.95 V typical forward voltage at 150 °C junction temperature; used as freewheeling and output rectification diode in industrial SMPS and UPS systems.
For engineers reviewing the STTH120L06TV1 datasheet, STTH120L06TV1 pinout, STTH120L06TV1 application, or STTH120L06TV1 equivalent, key selection criteria include reverse recovery time (trr ≤ 70 ns), thermal resistance (Rth(j-c) = 0.98 °C/W per diode), insulated 2500 VRMS isolation, dual-diode configuration, and conduction loss equation P = 0.93 × IF(AV) + 0.0045 × IF²(RMS).
Technical Context
This device implements ST's Turbo 2 silicon technology to achieve ultrafast switching with soft recovery characteristics, minimizing EMI and voltage overshoot during turn-off. Its dual-diode structure shares a common heatsink-mountable case with internal coupling thermal path (Rth(c) = 0.1 °C/W), enabling coordinated thermal management in high-power dual-channel rectification.
The ISOTOP package provides reinforced insulation (2500 VRMS) between terminals and heatsink, supporting direct mounting without additional insulators. Dynamic performance is characterized under standardized conditions: trr measured at IF = 0.5 A, Irr = 0.25 A, IR = 1 A; IRM up to 19 A at dIF/dt = 400 A/µs and Tj = 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage per diode; defines usable input voltage range in boost PFC or DC-DC stages. |
| IF(AV) | 60 A per diode - Average forward current rating at TC = 65 °C; supports continuous 120 A total dual-diode output in balanced designs. |
| trr (max) | 70 ns - Maximum reverse recovery time at 25 °C; enables operation up to ~2 MHz switching frequency with low turn-off loss. |
| VF (typ) | 0.95 V at Tj = 150 °C, IF = 60 A - Low conduction drop reduces power loss and heatsink sizing requirements. |
| Rth(j-c) | 0.98 °C/W per diode - Junction-to-case thermal resistance; allows accurate junction temperature estimation from measured case temperature. |
| IR (max) | 500 µA at Tj = 125 °C, VR = VRRM - Low leakage preserves efficiency in high-temperature industrial environments. |
| IFS M | 500 A - Non-repetitive surge current capability (10 ms sine); withstands inrush and fault transients in motor drives and UPS. |
Pinout & Package
The STTH120L06TV1 uses the ISOTOP (Insulated Super Top) package: a 4-terminal, heatsink-mountable, electrically insulated metal package with 2500 VRMS isolation between terminals and mounting surface. Dimensions: 38.0 mm × 25.3 mm × 12.0 mm (L × W × H), weight 27 g (without screws).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first diode; connects to high-side switch node in center-tapped or dual-output rectifiers. |
| K1 | Cathode 1 | Output terminal for first diode; ties to common output rail or filter capacitor positive. |
| A2 | Anode 2 | Input terminal for second diode; enables independent or interleaved rectification paths. |
| K2 | Cathode 2 | Output terminal for second diode; supports dual-output or parallel-configured outputs with shared thermal path. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast switching | trr ≤ 70 ns ensures minimal turn-off loss and reduced snubber requirements in >100 kHz SMPS. |
| Low thermal resistance | Rth(j-c) = 0.98 °C/W per diode enables higher power density by limiting ΔTj rise under load. |
| Insulated ISOTOP package | 2500 VRMS isolation eliminates need for mica washers or silicone pads when mounted to grounded heatsinks. |
| Soft recovery characteristic | S-factor > 1.0 across dIF/dt range suppresses voltage ringing and EMI generation during commutation. |
| Low conduction loss | VF = 0.95 V (typ) at 150 °C reduces I²R heating and improves full-load efficiency in 3–5 kW systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MBR12060CT | 600 V, 60 A dual Schottky; VF ≈ 0.85 V at 25 °C but degrades above 125 °C; no trr spec (inherently zero). | Lower conduction loss at room temp; unsuitable above 125 °C due to rapid IR increase; not rated for 600 V repetitive blocking. | Select only for <100 °C ambient, low-VF priority, and non-600 V blocking needs. |
| Vishay VS-120CN06 | 600 V, 120 A single-diode ultrafast; trr = 75 ns; Rth(j-c) = 0.5 °C/W; requires two devices for dual function. | Higher single-diode current rating but lacks integrated dual topology; no built-in insulation - requires external isolator. | Prefer when discrete thermal optimization is needed or when dual-anode/cathode routing is impractical. |
Compared with MBR12060CT, STTH120L06TV1 delivers stable 600 V blocking and predictable trr up to 150 °C; versus VS-120CN06, it integrates dual functionality and insulation in one package, reducing PCB area and assembly steps despite slightly higher Rth(j-c) per diode.

FAQ
What is the maximum recommended mounting torque for the STTH120L06TV1 ISOTOP package?
The manufacturer specifies a recommended torque value of 1.3 N·m and a maximum torque of 1.5 N·m for the mounting screws. STMicroelectronics strongly advises using only the screws supplied with the device; substitution invalidates warranty and risks mechanical damage or compromised thermal contact.
Can STTH120L06TV1 be used in parallel configurations for higher current handling?
Yes - its matched dual-diode structure and low thermal coupling resistance (Rth(c) = 0.1 °C/W) enable balanced current sharing when both diodes are operated under identical thermal and electrical conditions. External balancing resistors are not required if layout symmetry and heatsink uniformity are maintained.
Does the ISOTOP package require additional insulation when mounted to a grounded heatsink?
No - the ISOTOP package provides 2500 VRMS insulation between all terminals (A1, K1, A2, K2) and the mounting base. This eliminates the need for mica washers, silicone pads, or insulating sleeves, simplifying mechanical assembly and improving thermal transfer consistency.
How is conduction loss calculated for STTH120L06TV1 in design?
ST provides the empirical equation P = 0.93 × IF(AV) + 0.0045 × IF²(RMS) for estimating total conduction loss per diode. This accounts for both linear and quadratic components of VF behavior across temperature and current, validated per datasheet Figure 1 and applicable at TC = 65 °C with δ = 0.5 duty cycle.
