Product details
Overview
STTH16L06CFP from STMicroelectronics is a 600 V, 16 A ultrafast high-voltage rectifier diode in TO-220FPAB package, optimized for discontinuous-mode PFC boost stages and switching power supply output rectification. It delivers 1.05 V typical forward voltage at 150 °C, 35 ns max reverse recovery time, and 175 °C maximum junction temperature.
For engineers reviewing the STTH16L06CFP datasheet, STTH16L06CFP pinout, STTH16L06CFP application, or STTH16L06CFP equivalent, key selection criteria include ultrafast trr performance under high dIF/dt, low conduction loss at elevated Tj, thermal resistance (Rth(j-c) = 5 °C/W per diode), and TO-220FPAB's isolated tab for enhanced creepage/clearance in AC-DC systems.
Technical Context
This dual-diode configuration operates as a common-cathode ultrafast rectifier, with each die rated for 8 A average forward current (δ = 0.5) at Tc = 110 °C. Its Turbo 2 process enables soft reverse recovery (S factor > 0.8 at 400 V/125 °C) and low IRM (4.5–6.5 A) under harsh dIF/dt conditions up to 100 A/µs.
Designed for high-frequency PFC and SMPS secondary-side rectification, it sustains 600 V repetitive peak reverse voltage while maintaining low thermal resistance coupling (Rth(c) = 2.5 °C/W) between dies in the TO-220FPAB package-critical for balanced thermal sharing in dual-die operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands full bridge or boost stage DC bus voltages up to 400 V RMS input with margin. |
| IF(AV) per diode | 8 A at Tc = 110 °C - Enables compact heatsinking in space-constrained 300–500 W PFC designs. |
| VF (typ) | 1.05 V at IF = 8 A, Tj = 150 °C - Reduces conduction loss by ~15% vs. standard fast diodes at full load and high ambient. |
| trr (max) | 35 ns at IF = 0.5 A, VR = VRRM - Minimizes switching loss and EMI generation in 65–100 kHz PFC controllers. |
| Rth(j-c) per diode | 5 °C/W - Matches TO-220FPAB's isolated tab layout; allows independent thermal modeling of each die. |
| IRM (max) | 6.5 A at dIF/dt = 100 A/µs - Limits voltage overshoot across snubbers and MOSFETs during turn-off transitions. |
| Tj(max) | 175 °C - Supports operation in sealed industrial enclosures without derating below 125 °C ambient. |
Pinout & Package
TO-220FPAB package features an electrically isolated metal tab (pin 1), enabling direct mounting to heatsink without insulating washer. The device contains two ultrafast diodes sharing a common cathode connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Pin 1) | Anode 1 | Electrically isolated metal tab; connects to first diode anode; requires no insulator when mounted to grounded heatsink. |
| Pin 2 | Cathode (common) | Internal connection point for both diode cathodes; serves as main current return path in dual-diode topology. |
| Pin 3 | Anode 2 | Second diode anode; enables independent routing of two AC inputs or interleaved PFC phases. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast switching | 35 ns trr (max) ensures minimal dead-time loss and reduced EMI in 65–100 kHz PFC stages. |
| Low reverse recovery current | IRM ≤ 6.5 A at 100 A/µs dIF/dt prevents excessive voltage spikes across switching FETs. |
| Soft recovery characteristic | S factor > 0.8 reduces ringing and stress on gate drivers and snubber components. |
| High junction temperature rating | 175 °C Tj(max) supports reliable operation in sealed industrial power supplies without forced air. |
| Isolated tab package | TO-220FPAB's insulated tab eliminates need for mica washers, simplifying assembly and improving thermal contact. |

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 package with non-isolated tab; Rth(j-c) = 2.5 °C/W per diode. | Requires insulating washer for heatsink mounting; better suited for single-die layouts where isolation is not required. | Select when cost sensitivity outweighs creepage requirements and PCB layout permits insulator use. |
| IXYS MUR1660CT | 600 V, 16 A dual ultrafast diode; trr = 50 ns (max); VF = 1.25 V (typ) at 150 °C. | Higher conduction and switching losses; less suitable for high-efficiency PFC above 93%. | Choose only if STTH16L06CFP is unavailable and system efficiency budget allows ≥0.5% penalty. |
Compared with STTH16L06CT, the CFP variant trades 2.5 °C/W lower thermal resistance for electrical isolation-critical in medical or industrial AC-DC where reinforced insulation is mandated. Versus MUR1660CT, it delivers 15% lower VF and 30% faster trr, directly enabling higher frequency operation and reduced snubber losses.

FAQ
What is the maximum continuous forward current per diode at 110 °C case temperature?
The STTH16L06CFP supports 8 A average forward current per diode at Tc = 110 °C with 50% duty cycle (δ = 0.5), as specified in Table 2. This rating assumes proper heatsinking to maintain case temperature and accounts for thermal coupling between the two dies in the TO-220FPAB package.
Does the TO-220FPAB package provide electrical isolation between the tab and leads?
Yes-the TO-220FPAB package features an electrically isolated metal tab (Pin 1), rated for 2500 VAC isolation per UL 60950. This eliminates the need for insulating washers when mounting to a grounded heatsink, simplifying assembly and improving thermal reliability in safety-critical AC-DC designs.
How does the soft recovery characteristic affect EMI in PFC circuits?
With a softness factor > 0.8 at 125 °C, the STTH16L06CFP limits di/dt during reverse recovery, reducing high-frequency ringing and voltage overshoot. This directly lowers conducted EMI in the 150 kHz–30 MHz band, easing compliance with EN 55032 Class B without additional RC snubbers on the boost diode.
Can this diode be used in synchronous rectification topologies?
No-STTH16L06CFP is a passive silicon PN junction diode, not a MOSFET-based synchronous rectifier. It lacks gate control and cannot be actively turned off. It is intended for hard-commutated rectification in boost, flyback, and LLC secondary stages where unidirectional conduction and ultrafast recovery are required.
