Product details
Overview
STTH10LCD06CT from STMicroelectronics is a dual common-cathode ultrafast high-voltage rectifier diode in TO-220AB package, rated for 600 V repetitive peak reverse voltage, 10 A total average forward current (5 A per diode), and 25 ns maximum reverse recovery time at 25 °C. It employs Turbo2 technology to minimize conduction and switching losses in interleaved PFC stages of high-efficiency SMPS.
For engineers reviewing the STTH10LCD06CT datasheet, STTH10LCD06CT pinout, STTH10LCD06CT application, or STTH10LCD06CT equivalent, key selection criteria include reverse recovery time under dIF/dt stress, thermal resistance junction-to-case (4.5 °C/W per diode), low leakage (<50 µA at 150 °C), soft recovery behavior, and compatibility with high-frequency PFC topologies requiring low EMI and high efficiency.
Technical Context
This dual-diode rectifier integrates two independent ultrafast silicon PN junctions sharing a common cathode terminal, enabling synchronous operation in bridge or center-tap configurations. Its Turbo2 process delivers controlled minority-carrier lifetime for optimized trr–VF trade-off, with typical VF of 1.25 V at 5 A and 150 °C.
Dynamic performance is characterized by soft reverse recovery (SFACTOR > 2.5 at 125 °C), low QRR (≤300 nC), and stable trr across temperature (25–50 ns) and dIF/dt (up to 500 A/µs). Thermal design relies on low Rth(j-c) = 4.5 °C/W per diode and direct metal tab conduction to heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak reverse voltage in 400 V AC-input PFC boost stages without avalanche breakdown. |
| IF(AV) per diode | 5 A - Supports continuous 10 A total device current in dual-phase interleaved PFC with thermal derating at Tc = 130 °C. |
| trr (max) | 25 ns at 25 °C - Enables switching frequencies up to 300 kHz with minimal turn-off loss and EMI generation. |
| VF (typ) | 1.25 V at 5 A, 150 °C - Reduces conduction loss to ~6.25 W per diode at full load, critical for thermal management. |
| Rth(j-c) per diode | 4.5 °C/W - Allows ≤75 °C junction rise above case at 5 A, supporting compact heatsink designs in space-constrained SMPS. |
| IRM (max) | 2.5 A at 125 °C - Limits peak reverse recovery current to reduce snubber stress and MOSFET gate ringing in hard-switched PFC. |
| IR @ 150 °C | 50 µA - Ensures negligible leakage power loss and stable bias in high-temperature industrial environments. |
Pinout & Package
TO-220AB package with isolated metal tab (electrically connected to cathode), three leads: two anodes (A1, A2) and one common cathode (K). Mounting via M3 screw with torque 0.4–0.6 N·m; epoxy meets UL94 V0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first diode leg; connects to phase 1 of interleaved PFC inductor or bridge arm. |
| A2 | Anode 2 | Input terminal for second diode leg; enables dual-phase rectification without external parallel diodes. |
| K | Common Cathode | Shared output node tied to bulk capacitor positive rail; requires low-inductance PCB layout for EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast switching (trr ≤25 ns) | Minimizes turn-off energy loss and di/dt-induced voltage spikes in 100–300 kHz PFC converters. |
| Low thermal resistance (Rth(j-c) = 4.5 °C/W) | Enables higher power density by reducing heatsink size and cost in 500 W–1 kW SMPS designs. |
| Soft reverse recovery (SFACTOR > 2.5) | Suppresses high-frequency ringing and EMI during commutation, easing EMC filter design. |
| Low IR at high Tj (50 µA @ 150 °C) | Maintains reliability and efficiency in sealed enclosures or high-ambient industrial applications. |
| Turbo2 process technology | Optimizes carrier lifetime for balanced VF/trr trade-off-no external snubbers required in most 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 |
|---|---|---|---|
| STTH10LCD06CFP | Same die, TO-220FPAB package with insulated tab; Rth(j-c) = 7.5 °C/W per diode. | Used where electrical isolation from heatsink is mandatory; higher thermal resistance limits power density. | Select when creepage/clearance requirements prohibit direct-tab mounting, accepting 40% higher junction temperature rise at same current. |
| IXYS MUR1060CT | 600 V, 10 A dual, trr = 35 ns (max), VF = 1.7 V (typ @ 5 A, 25 °C); no soft recovery data published. | Higher VF increases conduction loss by ~0.45 W per diode; slower trr raises EMI risk in high-dF/dt PFC. | Acceptable for cost-sensitive 100–150 kHz designs where thermal margin exists and EMI filtering is already robust. |
Compared with STTH10LCD06CT, the STTH10LCD06CFP trades thermal performance for isolation safety, while the MUR1060CT offers lower cost but sacrifices 40% faster recovery and 0.45 V lower VF-critical for efficiency and thermal headroom in high-frequency PFC.

FAQ
Is STTH10LCD06CT suitable for use with SiC MOSFETs in PFC stages?
Yes. Its 25 ns trr, soft recovery (SFACTOR > 2.5), and low QRR minimize voltage overshoot and gate ringing when commutated by fast-switching SiC devices. Measured VFP remains ≤5 V under 100 A/µs dIF/dt, ensuring safe operation without additional clamping.
What is the maximum continuous current per diode at 100 °C case temperature?
Per Table 2, IF(AV) per diode is rated at 5 A with Tc = 130 °C for TO-220AB. At Tc = 100 °C, derating is not specified, but thermal modeling using Rth(j-c) = 4.5 °C/W shows 5 A yields ~65 °C junction rise-well within 175 °C limit. Full 5 A per diode is permissible at 100 °C case.
Does the common cathode configuration require special PCB layout considerations?
Yes. The shared K terminal must be routed with minimal inductance to the bulk capacitor, using wide copper pours and multiple vias. Separation between A1 and A2 traces prevents cross-coupling; ground plane beneath the tab improves thermal transfer and EMI shielding.
How does STTH10LCD06CT compare to standard fast recovery diodes in terms of EMI reduction?
Its soft recovery (SFACTOR > 2.5) and low dV/dt during turn-off reduce high-frequency spectral content above 30 MHz by ≥10 dB compared to standard FRDs. This lowers conducted EMI filter component count and simplifies compliance testing for EN 55032 Class B.
