Product details
Overview
STTH16L06CG-TR from STMicroelectronics is a 600 V, 16 A ultrafast high-voltage rectifier diode in D2PAK package, optimized for discontinuous-mode PFC boost stages and switching power supply output rectification. It delivers typ. 1.05 V forward voltage at 150 °C and 8 A, 35 ns reverse recovery time, and 175 °C maximum junction temperature - enabling high-efficiency, thermally robust operation in industrial SMPS.
For engineers reviewing the STTH16L06CG-TR datasheet, STTH16L06CG-TR pinout, STTH16L06CG-TR application, or STTH16L06CG-TR equivalent, key selection criteria include reverse recovery performance under dIF/dt stress, thermal resistance (Rth(j-c) = 1.6 °C/W total), conduction loss modeling (P = 1.06×IF(AV) + 0.036×IF²(RMS)), and D2PAK mounting compatibility with FR4 PCB copper area.
Technical Context
This dual-diode configuration operates as a common-cathode ultrafast rectifier, where both anodes are electrically isolated and share one cathode terminal. Its Turbo 2 silicon process enables low Qrr (typ. 35 nC at dIF/dt = 100 A/µs, VR = 400 V) and soft recovery (S factor > 0.8), reducing EMI and snubber losses in high-frequency PFC circuits.
The device is rated for 16 A average forward current per diode at Tc = 130 °C in D2PAK, with junction-to-case thermal resistance of 1.6 °C/W (total), and supports surge currents up to 120 A (10 ms sinusoidal). Reverse leakage remains ≤240 µA at 150 °C and 600 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - withstands peak reverse voltages in 400 V AC input PFC and 380 V DC bus applications without breakdown. |
| IF(AV) per diode | 16 A at Tc = 130 °C - supports high-current output rectification in 500–1000 W industrial SMPS designs. |
| trr (max) | 35 ns - enables operation at ≥100 kHz switching frequencies while minimizing turn-off losses and voltage overshoot. |
| VF (typ) | 1.05 V at 8 A, 150 °C - reduces conduction loss by ~15% vs. standard fast diodes, improving full-load efficiency. |
| Rth(j-c) total | 1.6 °C/W - allows direct heatsinking via D2PAK tab; achieves <90 °C junction rise at 16 A continuous with 25 cm² 35 µm Cu on FR4. |
| IRM (max) | 6.5 A at 125 °C - limits peak reverse recovery current, easing gate driver stress in synchronous rectifier companion designs. |
| Tj(max) | 175 °C - supports operation in enclosed industrial enclosures with ambient up to 85 °C and limited airflow. |
Pinout & Package
D2PAK (TO-263AB) surface-mount package with isolated anodes (A1, A2) and common cathode (K); thermally enhanced exposed metal tab for PCB heatsinking. Recommended copper area: ≥20 cm² (FR4, 35 µm Cu) for Rth(j-a) ≤ 30 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first rectifier path; electrically isolated from A2; connects to PFC boost switch node or primary-side transformer winding. |
| A2 | Anode 2 | Input terminal for second rectifier path; independent of A1; used for dual-output or interleaved PFC configurations. |
| K | Common Cathode | Shared output node; carries combined forward current from both diodes; must be routed with low-inductance, high-current trace to bulk capacitor. |
| Tab | Junction-to-Case Thermal Path | Electrically connected to cathode (K); provides primary thermal conduction path to PCB copper; requires solder mask opening and thermal vias. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery (trr ≤ 35 ns) | Enables >100 kHz PFC operation with minimal switching loss and reduced EMI filter size. |
| Low Qrr (typ. 35 nC) | Reduces energy dissipated during turn-off, lowering MOSFET voltage spikes and snubber component stress. |
| Soft recovery (S factor > 0.8) | Suppresses current ringing and dv/dt-induced false triggering in adjacent gate drivers. |
| 175 °C Tj(max) rating | Permits derating margin for long-term reliability in high-ambient industrial environments (e.g., motor drives, UPS). |
| D2PAK thermal performance (Rth(j-c) = 1.6 °C/W) | Supports compact layout without external heatsink in 500–800 W systems using 2–3 oz copper PCB areas. |

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 |
|---|---|---|---|
| STTH16L06CT | Same die, TO-220AB through-hole package; Rth(j-c) = 2.5 °C/W per diode (vs. 1.6 °C/W total for CG); no tape-and-reel option. | Suitable for prototyping or low-volume industrial controls where manual assembly and heatsink mounting are preferred. | Select CT for lab validation or low-MOQ builds; CG-TR is optimal for automated SMT production of high-power SMPS. |
| IXYS MUR1660CT | 600 V, 16 A dual ultrafast; trr = 50 ns (max); VF = 1.7 V (typ, 25 °C); Rth(j-c) = 2.0 °C/W per diode; no soft recovery spec. | Higher conduction loss and slower recovery increase EMI and reduce efficiency in >75 kHz PFC designs. | Choose MUR1660CT only if STTH16L06CG-TR is unavailable and design tolerates +0.65 V higher VF and +15 ns trr penalty. |
Compared with STTH16L06CT and MUR1660CT, STTH16L06CG-TR offers superior thermal performance (1.6 °C/W vs. ≥2.0 °C/W), lower VF at elevated temperature, and documented soft recovery - making it the preferred choice for high-density, high-efficiency automated production of industrial PFC and SMPS modules.

FAQ
What is the maximum average forward current rating for STTH16L06CG-TR in D2PAK package?
The STTH16L06CG-TR is rated for 16 A average forward current per diode at case temperature Tc = 130 °C, as specified in Table 2 of the official datasheet (Doc ID 10760 Rev 2). This rating assumes proper PCB copper area (≥20 cm²) and thermal via implementation to maintain the specified thermal resistance of 1.6 °C/W (total).
Does STTH16L06CG-TR have a soft recovery characteristic, and how is it quantified?
Yes, STTH16L06CG-TR exhibits soft recovery, quantified by the softness factor (S factor) ≥0.8 at dIF/dt = 100 A/µs and Tj = 125 °C (Figure 8). This means reverse recovery current decays gradually rather than abruptly, reducing EMI generation and voltage overshoot across switching devices in the same circuit.
Can STTH16L06CG-TR be used in place of a single-diode 600 V rectifier in a design?
Yes - the STTH16L06CG-TR contains two independent ultrafast diodes sharing a common cathode. Either anode (A1 or A2) can be used individually with K as a single 600 V, 16 A rectifier; the unused anode must be left unconnected or tied to a non-switching potential to avoid parasitic conduction paths.
What is the recommended torque for mounting STTH16L06CG-TR when used with a heatsink?
The STTH16L06CG-TR is a surface-mount D2PAK device and does not use mechanical screws or torque-based mounting. Thermal transfer relies entirely on solder joint integrity and PCB copper area. For through-hole alternatives like STTH16L06CT, ST specifies 0.4–0.6 N·m torque - but this does not apply to the CG-TR variant.
