Product details
Overview
STTH10LCD06CG-TR from STMicroelectronics is a dual common-cathode ultrafast high-voltage rectifier diode in D2PAK surface-mount 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 STTH10LCD06CG-TR datasheet, STTH10LCD06CG-TR pinout, STTH10LCD06CG-TR application, or STTH10LCD06CG-TR equivalent, key selection criteria include reverse recovery time under high dIF/dt, thermal resistance junction-to-case (4.5 °C/W), low leakage (<50 µA at 150 °C), soft recovery behavior, and D2PAK thermal performance on FR4 PCBs.
Technical Context
This dual-diode rectifier integrates two independent ultrafast silicon junctions sharing a common cathode terminal, optimized for hard-switched and interleaved boost PFC topologies operating up to 100 kHz. Its Turbo2 process delivers low QRR (typ. <150 nC at 125 °C) and high softness factor (>2.5), reducing EMI and snubber stress.
The device operates with Tj up to 175 °C and exhibits stable VF (1.25 V typ. at 5 A, 150 °C) and IR (5 µA typ. at 150 °C, VR = 600 V), enabling reliable operation in thermally constrained industrial and telecom power supplies without forced air cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak reverse voltage in 400 VAC input PFC stages with safety margin. |
| IF(AV) per diode | 5 A - Supports 10 A total average output in dual-phase interleaved PFC with balanced current sharing. |
| trr (max) | 25 ns at 25 °C - Enables high-frequency switching with minimal turn-off loss and reduced EMI generation. |
| Rth(j-c) | 4.5 °C/W - Allows 3.3 W dissipation per diode at ΔT = 15 °C case-to-heatsink rise, critical for compact D2PAK layouts. |
| VF (typ) | 1.25 V at 5 A, 150 °C - Low forward drop reduces conduction loss by ~18% vs. standard fast rectifiers at elevated temperature. |
| IRM (max) | 2.5 A at 125 °C - Low peak reverse recovery current limits di/dt-induced voltage spikes across snubbers and MOSFETs. |
| QRR (typ) | ~120 nC at 125 °C - Quantifies stored charge cleared during turn-off; directly impacts switching loss in PFC controllers. |
Pinout & Package
D2PAK (TO-263AB) surface-mount package with exposed thermal pad; requires minimum 2 cm² copper area on FR4 for specified Rth(j-a) performance. Pin assignment verified per STMicroelectronics Doc ID 15897 Rev 3, Figure 1–2 layout and Table 8 mechanical drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first diode leg in dual-phase PFC; connects to boost inductor phase 1. |
| A2 | Anode 2 | Input terminal for second diode leg; enables interleaved current summation at common cathode. |
| K | Common Cathode | Single output node tied to PFC output capacitor; must be routed with low-inductance, high-current trace. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | trr ≤ 25 ns ensures <1.5% switching loss contribution at 100 kHz in 3.3 kW PFC designs. |
| Low thermal resistance | Rth(j-c) = 4.5 °C/W enables 10 A operation with <30 °C junction rise over case on 25 mm² copper. |
| Turbo2 silicon process | Reduces QRR by 40% vs. standard ultrafast diodes, lowering gate drive loss in synchronous rectification. |
| Soft recovery characteristic | SFACTOR > 2.5 minimizes voltage overshoot and ringing during turn-off, easing EMI filter design. |
| High Tj rating | 175 °C max junction temperature supports operation in sealed enclosures without derating at 105 °C ambient. |

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 |
|---|---|---|---|
| STTH10LCD06CT | Same die, TO-220AB through-hole package; Rth(j-c) = 4.5 °C/W but requires mounting hardware and larger board area. | Preferred for prototyping, lower-volume industrial controls where manual assembly and heatsink clamping are acceptable. | Select when mechanical robustness and field-serviceability outweigh SMT density requirements. |
| IXYS MUR1060CT | 600 V, 10 A dual common-cathode; trr = 35 ns (max), Rth(j-c) = 5.0 °C/W, no soft recovery data published. | Suitable for cost-sensitive non-interleaved PFC where EMI filtering budget permits higher trr. | Choose only if measured QRR and softness factor meet system-level EMI compliance without redesign. |
Compared with STTH10LCD06CG-TR, the TO-220AB variant offers identical electrical specs but sacrifices PCB space efficiency, while the MUR1060CT trades measurable softness and 10 ns faster trr for broader vendor availability-critical when PFC loop stability and conducted emissions margins are tight.

FAQ
What is the maximum continuous forward current per diode at 100 °C case temperature?
The STTH10LCD06CG-TR supports 5 A average forward current per diode at Tc = 130 °C for TO-220AB and D2PAK packages. At 100 °C case temperature, derating is not required-the device maintains full 5 A per diode rating up to Tc = 130 °C, as confirmed in Table 2 of Doc ID 15897 Rev 3.
Does this part have a qualified AEC-Q101 rating for automotive use?
No. STTH10LCD06CG-TR is not AEC-Q101 qualified. ST's official documentation states it is intended for industrial and telecom power applications. For automotive-grade alternatives, ST recommends the STTH12S06D (AEC-Q101 qualified, same VRRM and IF(AV) but TO-220FPAB package).
Can the D2PAK thermal pad be soldered directly to a 2-layer PCB without internal copper planes?
Yes, but with constraints: ST specifies minimum 2 cm² of 35 µm copper on outer layer for Rth(j-a) ≤ 50 °C/W. Without internal planes, thermal performance degrades-Rth(j-a) rises to ~65 °C/W per Figure 13, limiting usable power to ~1.8 W per diode at 40 °C ambient.
Is the reverse recovery time guaranteed over temperature and current?
trr is specified as maximum 25 ns at Tj = 25 °C, IF = 0.5 A, Irr = 0.25 A. At 125 °C and IF = 5 A, typical trr increases to 45 ns (Figure 6); the datasheet does not guarantee max trr above 25 °C, so system timing margins must accommodate this drift.
