Product details
Overview
STTH60AC06CW from STMicroelectronics is a 600 V, 2 × 30 A dual ultrafast recovery rectifier diode in TO-247 package, designed for high-efficiency boost PFC stages and freewheeling roles in interleaved AC-DC converters. It delivers 40 ns typical reverse recovery time, 1.4 V typical forward voltage at 150 °C/30 A, and 175 °C maximum junction temperature - enabling compact, thermally robust air conditioning power supplies.
For engineers reviewing the STTH60AC06CW datasheet, STTH60AC06CW pinout, STTH60AC06CW application, or STTH60AC06CW equivalent, key selection criteria include dual-diode thermal coupling in TO-247, low conduction loss (1.07–1.40 V VF range), ultrafast trr stability across dIF/dt (50–70 ns at 125 °C), and insulated-package alternatives for high-voltage isolation requirements.
Technical Context
This dual ultrafast diode integrates two independent 600 V/30 A anode-cathode paths in a single TO-247 outline with shared case thermal path. Its Turbo 2 silicon technology enables soft reverse recovery (S-factor >1.0) and low QRR (typ. ~1200 nC at 125 °C), critical for reducing EMI and switching losses in continuous-conduction-mode PFC.
The device operates with Rth(j–c) = 0.55 °C/W total (0.9 °C/W per diode) and supports surge currents up to 280 A (10 ms sine), making it suitable for high-reliability industrial power conversion where thermal transients and repetitive overloads occur.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak reverse voltage in 400 VAC input PFC bus without breakdown. |
| IF(AV) per diode | 30 A - Sustains average forward current per die under δ = 0.5 duty cycle in boost diode position. |
| trr (typ) | 40 ns - Enables <100 kHz switching with minimal turn-off loss in interleaved PFC stages. |
| VF (typ @ 150 °C) | 1.4 V - Limits conduction loss to ~42 W per diode at 30 A DC, easing heatsink sizing. |
| Tj max | 175 °C - Allows operation in sealed HVAC enclosures with ambient up to 85 °C and ΔT ≤ 90 K. |
| Rth(j–c) total | 0.55 °C/W - Enables 110 W total dissipation before reaching Tj limit with 60 K case-to-ambient gradient. |
| IRM (typ) | 6.5 A - Low peak reverse recovery current reduces snubber stress and gate driver coupling risk. |
Pinout & Package
TO-247 package with three terminals: Cathode (K), Anode 1 (A1), Anode 2 (A2). Case is electrically isolated but thermally connected to both dies. Mounting hole center aligns with mechanical datum for standardized heatsink interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| K | Common cathode | Shared output node for dual-diode configuration; connects to PFC output rail or converter positive bus. |
| A1 | Anode of Diode 1 | Input terminal for first boost leg; ties to inductor switch node in interleaved topology. |
| A2 | Anode of Diode 2 | Input terminal for second boost leg; enables phase-shifted current sharing and ripple cancellation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 40 ns trr typ. at 25 °C ensures minimal dead-time loss and reduced EMI generation in 65–100 kHz PFC. |
| Low VF at high Tj | 1.07 V min. VF at 150 °C/30 A lowers conduction loss by ~22% vs. standard fast diodes at elevated temperature. |
| Dual-die thermal coupling | 0.55 °C/W total Rth(j–c) allows shared heatsinking while maintaining balanced thermal resistance between legs. |
| Soft recovery (S-factor >1) | S-factor ≥1.2 at 125 °C suppresses voltage overshoot during diode turn-off, reducing snubber component stress. |
| High surge rating | 280 A IFSM (10 ms) supports inrush and fault-current handling in HVAC compressor drive front-ends. |
Applications
| Air Conditioning PFC Boost Stage | Industrial SMPS Freewheeling |
|---|---|
|
Use Scenario: Interleaved 2-phase boost converter in inverter-driven HVAC outdoor units operating at 45–65 kHz. IC Role / Device Role / Timing Role: Dual ultrafast rectifier providing synchronous rectification path for each boost leg; defines minimum off-time via trr.

Use Scenario: High-current freewheeling path in 3 kW telecom rectifier with active clamp forward topology. IC Role / Device Role / Timing Role: Bidirectional energy return path during MOSFET off-state; clamps inductive kick with low VFP (2.5 V). Use Value: 1.4 V VF at 150 °C cuts conduction loss by 18 W per diode vs. legacy 1.75 V parts, lowering thermal design margin. |
| UPS Input Rectification | EV Charger Front-End |
|
Use Scenario: Three-phase 10 kW online UPS with active PFC using six-switch Vienna rectifier architecture. IC Role / Device Role / Timing Role: Upper-leg boost diode in split-phase configuration; handles 30 A avg. per diode with 100 °C case temp. Use Value: 175 °C Tj rating permits derating only 15% at 105 °C heatsink, extending service life in fanless UPS enclosures. |
Use Scenario: 11 kW AC/DC OBC in Level 2 EV charger with dual-phase interleaved PFC stage. IC Role / Device Role / Timing Role: Dual-anode rectifier enabling phase interleaving without discrete diode pairing; reduces layout parasitics. Use Value: Shared TO-247 case lowers thermal impedance by 30% vs. two separate TO-220 devices, improving thermal cycling reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual-diode rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH60AC06CPF | Same die, TO-3PF package with 2500 VDC insulation; Rth(j–c) = 2.2 °C/W total. | Required where reinforced isolation between primary and secondary sides is mandated (e.g., medical PSUs). | Select when creepage/clearance >8 mm and isolation testing to 2500 VDC is required; accept 4× higher thermal resistance. |
| IXYS MUR6060CT | 600 V/60 A single-die dual diode; trr = 65 ns typ.; VF = 1.7 V @ 150 °C/30 A. | Used in cost-sensitive industrial SMPS where 25 ns slower recovery is acceptable. | Choose for lower BOM cost where PFC efficiency >97.5% suffices and thermal budget allows higher VF penalty. |
Compared with STTH60AC06CW, STTH60AC06CPF trades thermal performance for isolation compliance, while MUR6060CT sacrifices 25 ns trr and +0.3 V VF to reduce unit cost - making STTH60AC06CW optimal for thermally constrained, high-efficiency HVAC and EV charging designs.

FAQ
What is the mounting torque specification for STTH60AC06CW?
The recommended mounting torque for the TO-247 package is 0.8 N·m, with a maximum allowable torque of 1.0 N·m. Exceeding this range risks cracking the epoxy body or deforming the leadframe, compromising thermal contact and long-term reliability. Use a calibrated torque screwdriver and apply even pressure across the mounting surface.
Can STTH60AC06CW replace a single 60 A diode in parallel configurations?
No - STTH60AC06CW contains two independent 30 A diodes sharing one case, not a single 60 A path. Its internal structure does not support paralleling the anodes or cathodes externally. For 60 A single-path applications, use STTH120R06CW or equivalent rated single-die devices.
Is STTH60AC06CW RoHS and REACH compliant?
Yes - STTH60AC06CW carries ECOPACK2 compliance, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full material declarations and substance thresholds are published in ST's official ECOPACK documentation referenced in DS9785 Rev 4.
How does the dual-diode configuration affect thermal measurement?
Thermal resistance is specified as 0.55 °C/W total (junction-to-case), measured with both diodes powered simultaneously. Individual diode Rth(j–c) is 0.9 °C/W, but simultaneous conduction causes mutual heating - so derating must follow the total 0.55 °C/W curve in Figure 4, not per-diode values.
