Product details
Overview
STTH15AC06CFP from STMicroelectronics is a 600 V, 15 A dual common-cathode ultrafast recovery rectifier in insulated TO-220FPAB package, featuring 25 ns max reverse recovery time, 1.5 V max forward voltage at 150 °C, and 175 °C max junction temperature. It serves as a boost diode in interleaved PFC stages for air conditioning systems and as a freewheeling diode in high-efficiency SMPS.
For engineers reviewing the STTH15AC06CFP datasheet, STTH15AC06CFP pinout, STTH15AC06CFP application, or STTH15AC06CFP equivalent, this device is selected for high-voltage, high-frequency switching where low conduction loss (1.2 × IF(AV) + 0.04 × IF²(RMS)), low trr, and thermal robustness (Rth(j-c) = 4.5 °C/W total) are critical in industrial power conversion designs.
Technical Context
The STTH15AC06CFP integrates two independent 7.5 A/600 V ultrafast diodes in a single insulated TO-220FPAB housing, sharing a common cathode terminal. Its Turbo 2 process enables low Qrr (typ. <100 nC at dIF/dt = 100 A/µs) and soft recovery (SFACTOR >1.0), minimizing EMI and voltage overshoot during hard-switching transitions.
Designed for continuous-conduction-mode (CCM) interleaved PFC, it sustains 80 A non-repetitive surge current and operates up to 175 °C junction temperature with 2500 VDC isolation between case and terminals - enabling direct heatsink mounting without insulating washers in compact AC-DC front-end designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage up to 600 V, suitable for 400 V DC bus applications with safety margin. |
| IF(AV) per device | 15 A - Total average forward current rating across both diodes, enabling high-power PFC stage operation. |
| trr (max) | 25 ns - Ultrafast recovery minimizes switching losses and reduces snubber requirements in >100 kHz converters. |
| VF (max) | 1.5 V at Tj = 150 °C, IF = 7.5 A - Low forward drop maintains efficiency under thermal stress in enclosed environments. |
| Rth(j-c) total | 4.5 °C/W - Thermal resistance from junction to insulated case enables direct heatsink coupling without thermal pad degradation. |
| IR (max) | 100 µA at Tj = 150 °C, VR = VRRM - Low leakage preserves efficiency in high-temperature standby modes. |
| IFS M | 80 A (tp = 10 ms) - Handles inrush and transient overloads in motor-driven HVAC power supplies. |
Pinout & Package
Package: TO-220FPAB - Insulated plastic package with 2500 VDC isolation between leads and metal tab; designed for direct heatsink mounting without additional insulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (Anode 1) | First anode connection | Input terminal for first diode leg in dual common-cathode configuration; electrically isolated from case. |

| K (Cathode) | Common cathode | Shared output node for both diodes; connects to DC bus capacitor positive rail in boost topology. |
| Tab (Case) | Insulated thermal path | Electrically isolated metal tab (2500 VDC rating); serves only as thermal interface to heatsink, not electrical node. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast switching | 25 ns max trr ensures minimal turn-off loss in 100–300 kHz PFC stages, reducing MOSFET voltage stress. |

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 |
|---|---|---|---|
| STTH15AC06CT | Same die, TO-220AB package (non-insulated); Rth(j-c) = 1.7 °C/W total but requires insulating washer for heatsink mounting. | Preferred where board-level isolation is managed externally and lower thermal resistance is prioritized over mechanical simplicity. | Select when heatsink isolation is already implemented and thermal performance outweighs assembly cost. |
| IXYS MUR1560CT | 600 V, 15 A dual common-cathode; trr = 35 ns (max), VF = 1.7 V (max) at 150 °C, no insulation rating specified. | Suitable for non-isolated chassis designs; higher VF increases conduction loss by ~0.3 W per diode at 7.5 A. | Choose only if existing BOM uses IXYS footprint and isolation is handled via layout or external barriers. |
Compared with STTH15AC06CT and MUR1560CT, the STTH15AC06CFP uniquely delivers certified 2500 VDC insulation in a thermally optimized package - eliminating insulator wear-out risk while maintaining competitive trr and VF, making it optimal for field-serviceable HVAC and industrial power systems.

FAQ
What is the maximum junction temperature and how does it affect thermal design?
The STTH15AC06CFP has a maximum junction temperature of 175 °C. This allows operation in high-ambient environments such as enclosed HVAC cabinets, but requires heatsink sizing based on Rth(j-c) = 4.5 °C/W and system airflow. Derating curves in Figure 1 show that at 15 A average current, junction-to-case temperature rise remains within safe limits only if case temperature stays below 130 °C.
Is the TO-220FPAB package truly isolated, and what is its isolation test voltage?
Yes - the TO-220FPAB package provides 2500 VDC isolation between all leads (A1, A2, K) and the metal tab, verified per IEC 60747-5-1. This rating is confirmed in the datasheet's "Features" section and Table 3, enabling direct heatsink mounting without supplemental insulation in safety-compliant designs.
How does the dual common-cathode configuration impact PCB layout in interleaved PFC?
The dual anode (A1/A2) and shared cathode (K) structure allows symmetrical placement of two boost chokes with independent gate drives, reducing input current ripple by up to 50%. Layout must maintain matched trace lengths from A1/A2 to respective MOSFET sources and minimize loop area around the K node to preserve soft recovery benefits.
Can STTH15AC06CFP replace STTH15AC06CT without redesigning the heatsink interface?
No - although both share identical die and pinout, the STTH15AC06CFP's insulated TO-220FPAB requires no insulating washer, whereas the STTH15AC06CT (TO-220AB) mandates one. Mechanical mounting torque (0.4–0.6 N·m) and screw clearance differ per package drawings; direct substitution risks thermal overload or electrical short without layout review.
