Product details
Overview
STTH30AC06FP from STMicroelectronics is a 600 V, 30 A ultrafast high-voltage rectifier diode in an insulated TO-220FPAC package, optimized for discontinuous-mode PFC boost stages and switching power supply output rectification. It delivers typ. 1.15 V forward voltage at 150 °C, 45 ns max reverse recovery time, and 3.5 °C/W junction-to-case thermal resistance.
For engineers reviewing the STTH30AC06FP datasheet, STTH30AC06FP pinout, STTH30AC06FP application, or STTH30AC06FP equivalent, key selection criteria include reverse recovery softness (SFACTOR >1.0), low IR (800 µA max at 150 °C), conduction loss modeling (P = 1.1×IF(AV) + 0.012×IF²(RMS)), and insulated package safety compliance (2000 VRMS).
Technical Context
This device implements ST's Turbo 2 silicon technology to achieve ultrafast switching with controlled soft recovery-critical for reducing EMI in high-frequency PFC and SMPS designs. Its 600 V VRRM rating supports universal-input AC/DC front-ends, while the 175 °C maximum junction temperature enables operation in thermally constrained industrial enclosures.
The TO-220FPAC package provides electrical insulation (2000 VRMS) between the die and mounting surface, eliminating need for insulating washers in heatsink-mounted configurations. Thermal performance is characterized by Rth(j-c) = 3.5 °C/W, enabling reliable 30 A continuous conduction under forced-air or moderate heatsink conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak reverse voltage in universal-input (85–265 VAC) PFC and offline SMPS applications without breakdown. |
| IF(AV) | 30 A - Sustains average forward current in high-power rectifier positions, e.g., 500 W+ boost PFC stages. |
| trr (max) | 45 ns - Enables operation up to ~200 kHz switching frequencies with minimal switching loss and voltage overshoot. |
| VF (typ.) | 1.15 V @ Tj = 150 °C, IF = 30 A - Directly determines conduction loss (Pcond ≈ 34.5 W at full load), critical for thermal design. |
| Rth(j-c) | 3.5 °C/W - Defines minimum heatsink requirement: ΔT = 3.5 × Pdiss; e.g., 34.5 W dissipation yields 121 °C rise above case. |
| IR (max) | 800 µA @ Tj = 150 °C, VR = VRRM - Low leakage preserves efficiency in high-temperature environments and reduces standby loss. |
| SFACTOR | >1.0 @ dIF/dt = 500 A/µs - Soft recovery minimizes ringing and EMI generation during turn-off in hard-switched topologies. |
Pinout & Package
STTH30AC06FP uses the TO-220FPAC package: insulated plastic housing with electrically isolated tab (2000 VRMS), 3-pin configuration (Anode, Cathode, Isolated Mounting Tab), and recommended mounting torque of 0.55 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input terminal for forward current flow | Connected to AC side or switch node in boost PFC; must withstand surge currents up to 270 A (10 ms sine). |
| Cathode (Pin 2) | Output terminal for forward current flow | Connects to DC bus or output capacitor; carries full load current and must be routed with low-inductance layout. |
| Isolated Tab (Pin 3) | Electrically isolated thermal interface | Mounts directly to heatsink without insulator; enables simplified thermal path while maintaining 2000 VRMS isolation from circuit ground. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | trr ≤ 45 ns with SFACTOR >1.0 ensures low EMI and reduced snubber stress in high-dV/dt PFC circuits. |
| Low thermal resistance | Rth(j-c) = 3.5 °C/W allows direct heatsink mounting without thermal derating penalties at 30 A continuous. |
| High-temperature operation | Tj(max) = 175 °C supports use in sealed industrial power supplies where ambient exceeds 85 °C. |
| Insulated package | TO-220FPAC provides 2000 VRMS isolation, eliminating creepage/clearance concerns when mounting to grounded heatsinks. |
| Low conduction loss model | Empirical loss equation P = 1.1×IF(AV) + 0.012×IF²(RMS) enables accurate thermal simulation without curve-fitting. |

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); no insulated tab; TO-247AC package. | Requires external insulator for heatsink mounting; higher trr increases EMI filtering burden in PFC. | Select when dual-diode topology is needed and isolation is handled via hardware, not package. |
| Vishay VS-30CPH06 | 600 V, 30 A; trr = 50 ns (max); VF = 1.25 V (typ.); TO-247AD package with isolated tab (1500 VRMS). | Lower isolation rating (1500 vs. 2000 VRMS); 0.1 V higher VF increases conduction loss by ~3 W at full load. | Acceptable where 1500 VRMS meets safety standards and thermal margin accommodates extra loss. |
Compared with MUR3060CT and VS-30CPH06, STTH30AC06FP offers superior isolation (2000 VRMS), lowest VF at high temperature, and tightest trr spec-making it optimal for space-constrained, high-efficiency PFC designs where thermal and EMI margins are critical.

FAQ
What is the maximum allowable heatsink temperature for continuous 30 A operation?
With Rth(j-c) = 3.5 °C/W and typical power dissipation of 34.5 W at 150 °C junction, the case temperature must stay ≤135.5 °C to maintain Tj ≤175 °C. Assuming 10 °C thermal interface resistance, maximum heatsink temperature is 125.5 °C under steady-state conditions with adequate airflow.
Can STTH30AC06FP replace STTH30AC06 in existing designs?
Yes-STTH30AC06FP is the insulated-package variant of STTH30AC06 (TO-220AC). Both share identical electrical specs, but FP adds 2000 VRMS isolation. Mechanical mounting differs: FP requires no insulator, while standard TO-220AC needs mica washer and shoulder washer for isolation.
How does the soft recovery characteristic affect EMI filter design?
With SFACTOR >1.0 and trr ≤45 ns, STTH30AC06FP produces significantly lower dI/dt-induced voltage spikes than standard fast diodes. This reduces differential-mode noise amplitude by ~8 dB, allowing smaller X-capacitors and fewer common-mode chokes in EN55032 Class B EMI filters.
Is the TO-220FPAC package RoHS and REACH compliant?
Yes-STTH30AC06FP carries ECOPACK®2 certification, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The epoxy mold compound is UL 94 V-0 rated, and lead finish is matte tin, fully compatible with lead-free reflow profiles.
