Product details
Overview
STPR860D from Diodes Incorporated is a 600 V, 8.0 A power factor correction (PFC) rectifier diode in TO-220AC package, featuring 30 ns reverse recovery time, 1.5 V max forward voltage at 8.0 A and 25°C, and 90 A peak surge current capability; used in boost PFC stages of AC-DC front-end power supplies for industrial SMPS and LED drivers.
For engineers reviewing the STPR860D datasheet, STPR860D pinout, STPR860D application, or STPR860D equivalent, key selection criteria include VRRM rating, tRR for high-frequency switching efficiency, thermal resistance (RΘJC = 3.0 °C/W), IFSM robustness, and low IR at elevated temperature.
Technical Context
This PFC diode employs a glass-passivated superfast silicon junction optimized for continuous conduction mode (CCM) boost converters operating at 65–135 kHz. Its 600 V VRRM supports universal input (85–265 VAC) designs with margin, while 30 ns tRR minimizes switching losses and EMI generation during turn-off.
The device delivers 8.0 A average forward current at TC = 100°C with low thermal resistance (3.0 °C/W junction-to-case), enabling compact heatsink integration. Reverse leakage remains ≤10 µA at 25°C and ≤1000 µA at 125°C, supporting stable operation in thermally demanding environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak line voltage + transients in universal-input PFC stages without breakdown. |
| I(AV) | 8.0 A @ TC = 100°C - Sustains continuous output current in 300–500 W industrial power supplies. |
| tRR | 30 ns - Enables efficient high-frequency switching in CCM boost PFC with minimal turn-off loss. |
| VF | 1.5 V max @ 8.0 A, 25°C - Reduces conduction loss and improves system efficiency vs. standard fast recovery diodes. |
| RΘJC | 3.0 °C/W - Allows direct mounting to heatsink for effective thermal management in enclosed enclosures. |
| IFSM | 90 A (8.3 ms half-sine) - Survives inrush and overload events without degradation in real-world AC mains conditions. |
| IR | ≤1000 µA @ 600 V, 125°C - Ensures stable blocking performance under worst-case thermal stress in automotive/industrial ambient. |
Pinout & Package
Package: TO-220AC - 3-lead, single-ended vertical plastic package with isolated tab; anode and cathode leads on same side, metal tab electrically connected to cathode; UL 94V-0 rated, lead-free, RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input terminal for AC/DC rectification path | Connects to boost inductor node; carries full load current during conduction phase. |
| Cathode (Lead 2) | Output terminal for DC bus connection | Connects to bulk capacitor positive rail; also tied to metal tab for thermal and electrical reference. |
| Tab (Cathode) | Thermal and electrical cathode extension | Provides low-thermal-resistance path to heatsink; must be electrically isolated unless circuit design requires common-cathode mounting. |
Key Features
| Feature | Design Value |
|---|---|
| Superfast switching (tRR = 30 ns) | Reduces turn-off energy loss and EMI in >100 kHz PFC controllers, improving efficiency by ~0.5% over standard FRDs. |
| Glass passivated chip | Ensures long-term reliability and moisture resistance in humid or high-bias stress environments per JESD22-A110. |
| Low VF (1.5 V max @ 8 A) | Lowers conduction loss by up to 15% vs. comparable 600 V FRDs, reducing heatsink size and system cost. |
| High IFSM (90 A) | Withstands repeated cold-start surges and lightning-induced transients without parametric shift or failure. |
| UL 94V-0 plastic package | Meets flammability safety requirements for Class I, Division 2 hazardous location equipment and medical power supplies. |
Applications
| Industrial Switch-Mode Power Supplies | LED Driver Front-Ends |
|---|---|

IC Role / Device Role / Timing Role: Cathode-connected PFC rectifier in boost topology; conducts during inductor discharge phase synchronized to PFC controller gate drive. Use Value: 30 ns tRR and 3.0 °C/W RΘJC enable >95% PFC efficiency at full load and 70°C ambient without forced air. | Use Scenario: 200 W outdoor LED streetlight driver with high-reliability requirements and wide ambient range (−40°C to +85°C). IC Role / Device Role / Timing Role: Primary rectifier in interleaved boost PFC stage; handles 8 A average current with low IR stability across temperature. Use Value: ≤1000 µA IR at 125°C prevents DC bus droop and maintains regulation accuracy in unventilated pole-mounted enclosures. |
| Server PSU Front-Ends | Automotive On-Board Chargers (OBC) |
Use Scenario: 1 kW redundant server PSU with dual-phase interleaved PFC using discrete diodes. IC Role / Device Role / Timing Role: High-current PFC rectifier paired with SiC MOSFETs; operates at 120 kHz with tight thermal coupling to copper heatsink.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PFC rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8L06W (STMicroelectronics) | 600 V, 8 A, tRR = 35 ns, VF = 1.7 V @ 8 A, RΘJC = 3.5 °C/W | Higher VF increases conduction loss; slightly slower recovery raises EMI filtering burden. | Prefer when legacy ST design reuse or dual-sourcing across multiple platforms is required. |
| DF08S60 (ON Semiconductor) | 600 V, 8 A, tRR = 45 ns, VF = 1.6 V @ 8 A, RΘJC = 3.2 °C/W, TO-220AC | Longer tRR reduces high-frequency efficiency; identical package enables drop-in mechanical replacement. | Select if lower-cost qualification path is prioritized and 5–10 W efficiency margin is acceptable. |
Compared with STTH8L06W and DF08S60, STPR860D offers the lowest combined tRR/VF product and best thermal resistance-critical for space-constrained, high-efficiency PFC designs where thermal headroom and EMI compliance are limiting factors.

FAQ
Is STPR860D qualified to AEC-Q101?
No, STPR860D is not AEC-Q101 qualified. While Diodes offers AEC-Q101 versions in the STPR family (e.g., STPR860DQ), this standard part is manufactured in IATF 16949-certified facilities but lacks formal automotive qualification testing. For automotive applications, contact Diodes directly for the Q-grade variant.
What is the maximum recommended case temperature for continuous operation?
The maximum case temperature for continuous operation is 100°C, as specified by the I(AV) = 8.0 A rating. Exceeding 100°C requires derating per the datasheet's thermal curves; sustained operation above 125°C risks irreversible parameter shift and reduced lifetime.
Can STPR860D replace STPR820D in a design?
Yes, STPR860D can replace STPR820D mechanically and electrically in most applications, as both share identical TO-220AC package, pinout, and thermal characteristics. However, its higher 600 V VRRM provides greater voltage margin-useful in designs with high line transients or future-proofing-but does not affect forward conduction behavior.
Does the metal tab require electrical isolation from the heatsink?
Yes-the metal tab is internally connected to the cathode. Unless the circuit design intentionally references the heatsink to the cathode potential (e.g., common-cathode multi-phase PFC), the tab must be electrically isolated using mica or polymer insulator kits and non-conductive thermal paste to prevent short circuits.
