Product details
Overview
STTH30L06CG from STMicroelectronics is a 600 V, ultrafast dual common-cathode high-voltage rectifier diode in D²PAK package, rated for 30 A RMS forward current and 15 A average per diode at TC = 140 °C, with 55 ns max reverse recovery time and 0.95 V typical forward voltage at 15 A/150 °C - optimized as boost diode in discontinuous/critical-mode PFC circuits.
For engineers reviewing the STTH30L06CG datasheet, STTH30L06CG pinout, STTH30L06CG application, or STTH30L06CG equivalent, key selection criteria include reverse recovery softness (S factor), thermal resistance (1.7 °C/W junction-to-case per diode), conduction loss equation (P = 0.94 × IF(AV) + 0.017 × IF²(RMS)), and ECOPACK®2 compliance for industrial power supply design.
Technical Context
This dual-diode rectifier employs ST's Turbo 2 silicon technology to achieve low trr (55 ns max) and low VF (0.95 V typ. @ 15 A/150 °C), enabling high-frequency switching in AC-DC front-ends. Its common-cathode configuration supports interleaved or parallel operation in two-phase PFC stages.
Thermal design is enabled by low Rth(j-c) of 1.7 °C/W per diode and coupling resistance of 0.6 °C/W between diodes, allowing accurate junction temperature estimation: ΔTj(diode1) = P(diode1) × 1.7 + P(diode2) × 0.6. The device operates up to Tj = +175 °C with IR ≤ 400 µA at 150 °C under VRRM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports 400 V AC input systems with ≥50 % safety margin against line surges |
| IF(AV) per diode | 15 A at TC = 140 °C - defines continuous DC output capability in single-phase PFC boost stage |
| trr (max) | 55 ns - enables operation up to ~300 kHz switching without excessive switching loss or EMI |
| VF (typ.) | 0.95 V @ 15 A / 150 °C - reduces conduction loss vs. standard fast recovery diodes (~15–20 % lower at full load) |
| Rth(j-c) per diode | 1.7 °C/W - allows direct heatsink mounting with predictable thermal rise under 30 A RMS total current |
| IRM (max) | 12 A @ dlF/dt = 100 A/µs - limits peak reverse current stress during hard-switching transitions |
| Qrr (typ.) | ~450 nC @ dlF/dt = 100 A/µs - quantifies stored charge contributing to turn-on loss in synchronous rectification |
Pinout & Package
D²PAK (TO-263) package with isolated tab (cathode-connected metal pad), 3-pin outline: two anodes (A1, A2) and one common cathode (K). Mounting torque: 0.8 N·m recommended (max 1.0 N·m). UL 94 V0 epoxy, ECOPACK®2 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first diode leg; connects to PFC inductor node in dual-phase topology |
| A2 | Anode 2 | Input terminal for second diode leg; enables interleaved or redundant conduction paths |
| K | Common cathode | Single output node tied to bulk capacitor positive rail; requires low-inductance layout to minimize ringing |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast switching | 55 ns trr max ensures minimal turn-off loss in >100 kHz PFC designs |
| Low thermal resistance | 1.7 °C/W junction-to-case per diode enables compact heatsinking in space-constrained PSUs |
| Reduced conduction losses | 0.95 V VF typ. at 15 A/150 °C lowers steady-state power dissipation vs. legacy FRDs |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant construction meets industrial environmental requirements |
| Soft reverse recovery | S-factor >0.8 across 100–500 A/µs dlF/dt range suppresses voltage overshoot and EMI generation |

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 |
|---|---|---|---|
| STTH30L06CW | Same die, TO-247 package; Rth(j-c) = 1.15 °C/W total (not per diode); higher mass, slower thermal response | Better suited for low-frequency (<50 kHz), high-current discrete heatsink mounting | Select when mechanical robustness and legacy TO-247 footprint compatibility outweigh surface-mount density needs |
| IXYS MUR3060CT | 600 V, 30 A dual, but trr = 75 ns max; VF = 1.25 V typ. @ 15 A/125 °C; no soft recovery data published | Higher conduction and switching loss; less suitable for CrCM or high-frequency PFC | Consider only if STTH30L06CG is unavailable and system efficiency targets allow ≥3 % loss increase |
Compared with STTH30L06CW and MUR3060CT, STTH30L06CG delivers superior high-frequency PFC performance via lower trr, softer recovery, and optimized D²PAK thermal interface - making it preferred for space-constrained, thermally demanding, and EMI-sensitive 100–300 kHz power supplies.

FAQ
What is the maximum allowable case temperature for continuous operation?
The STTH30L06CG supports continuous operation with TC ≤ 140 °C per diode for IF(AV) = 15 A, and TC ≤ 120 °C for IF(AV) = 20 A. Exceeding these temperatures requires derating per Figure 1 in the datasheet; junction temperature must not exceed +175 °C under any condition.
Can STTH30L06CG be used in single-diode configuration?
Yes - the device contains two independent diodes sharing a common cathode (K), so either anode (A1 or A2) can be used individually with K, while the unused anode is left unconnected. Thermal and electrical ratings apply per diode unless both are conducting simultaneously.
Is the D²PAK tab electrically isolated?
No - the metal tab in the D²PAK package is internally connected to the common cathode (K) terminal. It must be mounted on an electrically isolated heatsink or insulated thermal pad if the heatsink is grounded or at a different potential than the cathode rail.
How does the conduction loss equation P = 0.94 × IF(AV) + 0.017 × IF²(RMS) apply in practice?
This empirical equation models total conduction loss per diode using average and RMS current components. For example, at IF(AV) = 12 A and IF(RMS) = 25 A, loss = 0.94×12 + 0.017×625 = 11.28 + 10.625 = 21.9 W - confirming thermal design margins before prototype testing.
