Product details
Overview
STTH30AC06SP from STMicroelectronics is a 600 V, 30 A ultrafast high-voltage rectifier diode in TO3P-3L insulated package, optimized for discontinuous-mode PFC boost stages and switching power supply output rectification. It delivers 1.15 V typical forward voltage at 150 °C, 45 ns maximum reverse recovery time, and 800 µA max reverse leakage at 150 °C.
For engineers reviewing the STTH30AC06SP datasheet, STTH30AC06SP pinout, STTH30AC06SP application, or STTH30AC06SP equivalent, key selection criteria include junction-to-case thermal resistance (0.7 °C/W), soft recovery behavior (SFACTOR >1.0 at 100 A/µs), and RMS current rating (50 A) under conduction-cooled conditions.
Technical Context
This device implements ST's Turbo 2 silicon technology to achieve ultrafast switching with low stored charge (QRR <1200 nC at 100 A/µs) and soft reverse recovery (SFACTOR ≥1.5 up to 300 A/µs). Its 175 °C maximum junction temperature and low Rth(j-c) enable high-power-density designs without forced air cooling.
The TO3P-3L package provides 2000 VRMS insulation between case and die, supporting direct mounting to heatsinks without isolation pads. Dynamic parameters are characterized at IF = 30 A, dIF/dt = 100 A/µs, and VR = 400 V - matching real-world PFC boost diode stress conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports 400 V AC input PFC stages with 50% safety margin against line surges |
| IF(AV) | 30 A - continuous DC output current capability in bridge or single-phase rectifier topologies |
| trr (max) | 45 ns - enables operation at >100 kHz switching frequencies with minimal turn-off loss |
| Rth(j-c) | 0.7 °C/W - allows 42 W dissipation at ΔT = 30 °C (case-to-heatsink), enabling compact thermal design |
| VF (typ.) | 1.15 V @ Tj=150°C, IF=30A - reduces conduction loss to ~34.5 W (P ≈ 1.1×IF(AV) + 0.012×IF²(RMS)) |
| IRM (max) | 8 A - limits peak reverse recovery current during hard-switching transitions in boost converters |
| IR (max) | 800 µA @ Tj=150°C - ensures stable blocking in high-temperature industrial environments |
Pinout & Package
TO3P-3L is an insulated, 3-terminal through-hole package with metal tab (cathode), anode lead, and isolated mounting flange. Thermal path is direct from die to flange; electrical isolation (2000 VRMS) eliminates need for insulating washers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input terminal for forward conduction | Connected to AC side or switch node in boost PFC; must withstand surge current up to 270 A (10 ms) |
| Cathode (Tab) | Output terminal for forward conduction | Electrically isolated metal surface; serves as primary heat sink interface and DC output connection |
| Isolation Flange (Mounting Surface) | Thermal & electrical barrier | Rated 2000 VRMS isolation; permits direct bolt-down to grounded heatsink without dielectric pad |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | trr ≤ 45 ns ensures <5% switching loss contribution in 100 kHz PFC designs |
| Soft recovery characteristic | SFACTOR ≥1.5 minimizes EMI generation and voltage overshoot during diode turn-off |
| High-temperature operation | 175 °C max Tj enables use in sealed industrial enclosures without derating at full load |
| Low thermal resistance | 0.7 °C/W junction-to-case supports >40 W power dissipation with passive heatsinking |
| Insulated TO3P-3L package | 2000 VRMS isolation eliminates creepage/clearance constraints in Class I AC-DC systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MUR3060CT | 600 V, 30 A dual common-cathode; trr = 60 ns (max); Rth(j-c) = 1.0 °C/W; TO-247AC package | Requires insulating hardware; higher trr increases switching loss by ~22% in 100 kHz PFC | Preferred where dual-diode layout simplifies PCB routing but thermal margin is available |
| Vishay VS-30CPH06 | 600 V, 30 A; trr = 50 ns (max); VF = 1.25 V @ 150 °C; TO-247AD package; no isolation | Non-isolated package mandates dielectric pad; higher VF increases conduction loss by 9% at full load | Selected when cost sensitivity outweighs thermal/isolation advantages and heatsink isolation is already implemented |
Compared with MUR3060CT and VS-30CPH06, STTH30AC06SP offers superior thermal performance (0.7 vs. ≥1.0 °C/W), inherent isolation eliminating assembly steps, and tighter trr control-making it optimal for space-constrained, high-efficiency PFC and industrial SMPS where reliability and thermal headroom are critical.

FAQ
What is the maximum recommended mounting torque for the STTH30AC06SP TO3P-3L package?
The manufacturer specifies a torque range of 0.4 to 0.6 N·m for the TO3P-3L package. Exceeding 0.6 N·m risks mechanical damage to the internal bond wires or ceramic substrate, while torque below 0.4 N·m may compromise thermal contact and increase junction temperature by up to 12 °C under full load.
Can STTH30AC06SP replace STTH30AC06FP in existing designs?
Yes, but only if the thermal and isolation requirements align: STTH30AC06SP (TO3P-3L) offers lower Rth(j-c) (0.7 vs. 3.5 °C/W) and higher isolation (2000 VRMS), while STTH30AC06FP (TO-220FPAC) has smaller footprint and lower weight. PCB layout and heatsink interface must be revalidated due to different mounting geometry and thermal path.
How does the soft recovery factor (SFACTOR) impact EMI in PFC circuits?
SFACTOR ≥1.5 indicates gradual current decay during reverse recovery, reducing di/dt-induced voltage spikes across stray inductance. In a 2 kW PFC stage, this lowers conducted EMI above 150 kHz by 8–10 dB compared to diodes with SFACTOR <1.0, easing compliance with EN55022 Class B limits without additional snubbers.
Is STTH30AC06SP compliant with RoHS and REACH regulations?
Yes - STTH30AC06SP carries ECOPACK®2 certification per STMicroelectronics' environmental program, confirming full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including SVHC screening. Lead-free termination and halogen-free molding compound are standard.
