Product details
Overview
STTH12004TV1 from STMicroelectronics is a dual ultrafast high-voltage rectifier diode in ISOTOP package, rated for 400 V repetitive peak reverse voltage, 60 A average forward current per diode (120 A total RMS), and 50 ns maximum reverse recovery time at 125 °C. It serves as output rectification in high-frequency switching power supplies and industrial welding equipment.
For engineers reviewing the STTH12004TV1 datasheet, STTH12004TV1 pinout, STTH12004TV1 application, or STTH12004TV1 equivalent, key selection criteria include ultrafast trr performance, low conduction loss (VF = 0.83 V typ. @ 150 °C), thermal resistance (Rth(j-c) = 0.5 °C/W per diode), and dual-diode configuration for interleaved or parallel rectification topologies.
Technical Context
This dual-diode device integrates two independent ultrafast silicon rectifiers in a single ISOTOP thermally optimized package. Each diode features soft reverse recovery (Sfactor = 0.4 typ.), low VF (0.83 V @ 150 °C, 60 A), and low IR (50 µA @ 25 °C, 400 V).
Designed for high-efficiency, high-frequency operation, it supports dIF/dt up to 200 A/µs with controlled tfr (600 ns) and VFP (2.6 V), minimizing switching noise and EMI in hard-switched SMPS and inverter outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Withstands 400 V repetitive reverse voltage without breakdown, enabling use in 200–300 VDC bus applications. |
| IF(AV) per diode | 60 A @ Tc = 115 °C - Sustains 60 A average forward current per die under standard heatsink conditions. |
| trr (max) | 50 ns @ Tj = 125 °C, dIF/dt = 100 A/µs - Enables operation up to ~2 MHz switching frequency with minimal tail current loss. |
| VF (typ) | 0.83 V @ Tj = 150 °C, IF = 60 A - Low conduction loss reduces thermal load and improves system efficiency at full operating temperature. |
| Rth(j-c) per diode | 0.5 °C/W - Enables direct mounting to heatsink with predictable junction-to-case thermal path for dual-diode thermal management. |
| Sfactor | 0.4 typ. @ Tj = 125 °C - Soft recovery minimizes voltage overshoot and EMI during turn-off in inductive loads. |
Pinout & Package
The STTH12004TV1 uses the ISOTOP package: a 5-terminal, isolated metal-base power package with integrated thermal pad and screw-mounting holes. Terminals are arranged as two anode–cathode pairs sharing a common thermal base.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first diode; connects to high-side switching node in center-tapped or dual-output rectifier. |
| K1 | Cathode 1 | Output terminal for first diode; ties to +VOUT rail or shared cathode bus. |
| A2 | Anode 2 | Input terminal for second diode; enables interleaved or redundant rectification paths. |
| K2 | Cathode 2 | Output terminal for second diode; may be tied to K1 or used independently for dual-rail output. |
| Case (Metal Base) | Thermal & Electrical Isolation Plane | Electrically isolated mounting surface; provides low-impedance thermal path to heatsink without requiring insulating washers. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast switching | 50 ns trr max ensures minimal switching loss in 100 kHz–1 MHz SMPS designs. |
| Low thermal resistance | 0.5 °C/W j-c per diode allows >100 W dissipation per die with standard heatsinking. |
| Soft reverse recovery | Sfactor = 0.4 suppresses voltage ringing and reduces snubber component stress. |
| Dual-diode integration | Two independent 400 V / 60 A rectifiers in one package reduce PCB area and interconnect inductance. |
Applications
| Switch-Mode Power Supply Output Rectification | Industrial DC Welding Output Stage |
|---|---|

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 |
|---|---|---|---|
| STTH12003TV1 | 300 V VRRM, identical ISOTOP package and pinout | Lower voltage rating limits use to ≤150 VDC bus systems | Select when system reverse voltage stays below 300 V and thermal margin permits same footprint. |
| IXYS MUR1260CT | 600 V VRRM, TO-247AC package, 65 ns trr (max) | Higher voltage headroom but larger footprint and higher Rth(j-c) = 0.9 °C/W | Choose for 400–600 V systems where ISOTOP mounting is unavailable or higher surge rating is required. |
Compared with STTH12004TV1, STTH12003TV1 trades voltage rating for identical thermal performance in the same package, while IXYS MUR1260CT offers higher VRRM at the cost of slower recovery and reduced thermal efficiency-making STTH12004TV1 optimal for 400 V, high-frequency, space-constrained rectification.

FAQ
Is STTH12004TV1 still in active production?
No-STTH12004TV1 is marked as Obsolete Product(s) in the official ST datasheet (Rev. 1, October 2005). However, Aetrix Electronics maintains legacy inventory with full traceability and supports design-in continuity through controlled allocation and cross-reference guidance for functionally aligned replacements.
What is the maximum junction temperature and how does it affect derating?
The absolute maximum junction temperature is 150 °C. Derating begins at Tc > 115 °C: IF(AV) must be linearly reduced from 60 A to 0 A between 115 °C and 150 °C case temperature. Thermal design must ensure Rth(j-c) × Pdiss + Tc ≤ 150 °C under worst-case load.
Can STTH12004TV1 be used in parallel configurations?
Yes-its matched dual-diode structure and low thermal resistance support parallel operation. Use separate gate drivers or current-sharing resistors if connecting anodes/cathodes externally; avoid paralleling across different packages due to VF mismatch above 100 °C.
Does STTH12004TV1 require a heatsink, and what mounting torque is recommended?
Yes-a heatsink is mandatory for continuous operation above 20 A per diode. Mount using M4 screws at 0.7–0.9 N·m torque with thermal interface material. The ISOTOP base is electrically isolated, so no insulating washer is needed unless system grounding requires additional isolation.
