Product details
Overview
STTH30R06CW from STMicroelectronics is a 600 V, dual ultrafast high-voltage rectifier diode in TO-247 package, optimized for continuous-conduction-mode (CCM) PFC boost stages and hard-switching power supplies. It delivers 15 A average forward current per diode, 50 ns max reverse recovery time, and 1.8 V typical forward voltage at 125 °C - enabling high-efficiency, thermally robust operation in industrial AC-DC front-ends.
For engineers reviewing the STTH30R06CW datasheet, STTH30R06CW pinout, STTH30R06CW application, or STTH30R06CW equivalent, key selection criteria include reverse recovery time under hard-switching dIF/dt conditions, thermal resistance (1.0 °C/W total junction-to-case), softness factor (0.15), conduction loss modeling (P = 1.16 × IF(AV) + 0.043 × IF²(RMS)), and TO-247 mechanical mounting torque (0.8 N·m recommended).
Technical Context
This dual-diode device implements ST's Turbo 2 silicon technology, featuring a planar edge-terminated structure with controlled carrier lifetime to achieve ultrafast recovery without excessive overshoot. Each diode operates independently with isolated cathodes (A1/K/A2 configuration), supporting interleaved or phase-split PFC topologies.
Dynamic performance is characterized under standardized test conditions: trr measured at IF = 1 A, dIF/dt = −50 A/μs, VR = 30 V (25 °C) and up to 50 ns at IF = 15 A, dIF/dt = −200 A/μs, VR = 400 V (125 °C); IRM peaks at 9.0 A under same high-stress conditions, while Qrr remains at 220 nC - critical for EMI and snubber design in high-frequency switching converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports 400 VAC input rectification with ≥1.5× safety margin in universal-input PFC stages |
| IF(AV) per diode | 15 A at Tc = 115 °C - enables 30 A total device rating in dual-leg configurations with shared heatsink |
| trr (max) | 50 ns - limits turn-off switching loss and dv/dt-induced shoot-through risk in >100 kHz PFC controllers |
| VF (typ.) | 1.8 V at 15 A, 125 °C - determines conduction loss baseline for thermal design and efficiency mapping |
| Rth(j-c) total | 1.0 °C/W - allows direct junction temperature estimation from case temperature in forced-air or heatsink-cooled systems |
| S factor | 0.15 - indicates soft, low-overshoot recovery behavior reducing EMI and gate-drive stress on paired MOSFETs |
| Qrr | 220 nC - defines stored charge dissipated during turn-off, directly impacting snubber sizing and switching loss |
Pinout & Package
TO-247 package with three terminals: two anodes (A1, A2) and one common cathode (K). Mounting hole centered between pins; requires 0.8 N·m torque for reliable thermal interface. Epoxy meets UL94 V0; lead-free and RoHS-compliant per ECOPACK® specifications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Input node for first rectifier leg; electrically isolated from A2; connects to PFC inductor or bridge output |
| K | Common Cathode | Shared output node for both diodes; ties to DC bus capacitor positive terminal or boost switch source |
| A2 | Anode of Diode 2 | Input node for second rectifier leg; independent path enables interleaved or dual-phase PFC implementation |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast switching | 50 ns max trr ensures minimal dead-time loss and compatibility with 100–300 kHz CCM PFC controllers |
| Low thermal resistance | 1.0 °C/W total Rth(j-c) enables 175 °C max junction operation with <40 °C case rise at full load |
| Reduced conduction loss | 1.8 V VF at 15 A/125 °C lowers I²R heating vs. standard fast diodes, improving system efficiency by ~0.3–0.5% |
| Soft recovery behavior | S factor = 0.15 suppresses voltage ringing and reduces EMI filter component count in Class B compliance designs |

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 MUR3060CT | 600 V, 30 A dual, 60 ns trr (max), VF = 2.1 V @ 15 A/125 °C, Rth(j-c) = 1.2 °C/W | Higher VF increases conduction loss; slightly slower recovery affects >200 kHz designs | Preferred where cost sensitivity outweighs 0.3 V VF penalty and thermal margin is ample |
| Vishay VS-30CPH06 | 600 V, 30 A dual, 45 ns trr (max), VF = 1.75 V @ 15 A/125 °C, Rth(j-c) = 0.95 °C/W, but no softness spec | Lacks published S factor; potential for higher EMI in sensitive RF environments | Selected when peak efficiency is prioritized and EMI filtering budget allows added suppression |
Compared with MUR3060CT and VS-30CPH06, STTH30R06CW offers the best balance of soft recovery (S = 0.15), thermal resistance (1.0 °C/W), and proven PFC reliability - making it optimal for noise-sensitive, high-density industrial and automotive-grade power supplies.

FAQ
What is the maximum junction temperature and how is it validated?
The STTH30R06CW has a maximum rated junction temperature of 175 °C, verified per JEDEC JESD22-A108 through accelerated life testing and thermal characterization. This rating is sustained under full-rated current (15 A per diode) with case temperature ≤115 °C, confirmed via transient thermal impedance curves in Figure 3 of the datasheet.
Can STTH30R06CW be used in parallel configurations?
Yes - its matched dual-diode structure and low thermal resistance (1.0 °C/W total) support parallel operation when mounted on a common heatsink with balanced PCB layout. However, individual anode routing and Kelvin-sense traces are required to avoid current imbalance; derating by 10% per additional paralleled unit is recommended.
How does the softness factor affect EMI performance?
A softness factor of 0.15 means the diode recovers with minimal current overshoot and dI/dt tail, reducing high-frequency spectral content above 30 MHz. This directly lowers conducted EMI amplitude, allowing smaller Y-capacitors and simplified common-mode chokes in EN 55032 Class B compliance designs.
Is the TO-247 package lead-free and RoHS compliant?
Yes - STTH30R06CW uses an ECOPACK®-compliant TO-247 package with lead-free terminations and halogen-free epoxy meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. Full material declarations and test reports are available via ST's Quality Portal upon request.
