Product details
Overview
DTH1506FP from Diodes Incorporated is a 15A, 600V hyper-fast epitaxial rectifier diode in ITO-220AC package, optimized for high-frequency switching applications including PFC stages in continuous conduction mode, DC/DC converters, and inverter freewheeling paths. It delivers 2.9V forward voltage at 15A/25°C, 30ns reverse recovery time, and 45μA leakage at 600V/25°C.
For engineers reviewing the DTH1506FP datasheet, DTH1506FP pinout, DTH1506FP application, or DTH1506FP equivalent, key selection criteria include soft-recovery behavior for EMI reduction, thermal resistance of 4°C/W (junction-to-case), and AEC-Q101 readiness for automotive-grade power conversion designs.
Technical Context
This hyper-fast rectifier employs epitaxial silicon construction with glass passivation to achieve soft reverse recovery characteristics critical for reducing switching losses and voltage overshoot in hard-switched topologies. Its 30ns tRR and 455nC QRR at 125°C support operation in continuous conduction mode (CCM) PFC boost stages up to 100kHz.
The device features a single-diode configuration with cathode-anode polarity confirmed by top-view marking and pin 1 designation. Thermal performance is defined by RθJC = 4°C/W and RθJL = 5°C/W, enabling direct heatsink mounting via the metal tab (pin 2) while maintaining junction temperature ≤150°C under 15A DC load at TC = 90°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600V - Maximum repetitive reverse blocking voltage; supports 400V AC input rectification with 50% safety margin in offline SMPS. |
| IO | 15A @ TC = +90°C - Continuous average forward current rating; requires heatsinking for sustained operation. |
| VF | 2.9V @ 15A, 25°C - Forward voltage drop determines conduction loss; increases to 2.1V at 125°C junction temp. |
| tRR | 30ns - Reverse recovery time measured at IF = 0.5A, IR = 1.0A; enables high-frequency operation with low switching loss. |
| IR | 45μA @ 600V, 25°C - Reverse leakage current; remains ≤600μA at 125°C, ensuring stable blocking in hot environments. |
| EAS | 21.7mJ - Non-repetitive avalanche energy rating; provides limited ruggedness against inductive turn-off transients. |
| RθJC | 4°C/W - Junction-to-case thermal resistance; defines minimum heatsink requirement for thermal management. |
Pinout & Package
Package: ITO-220AC (Type WX-NC), molded plastic with matte tin–annealed copper leadframe, UL 94V-0 rated, 1.5g weight. Metal tab (pin 2) serves as cathode connection and thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Input terminal for forward current flow; connects to switching node in boost PFC or inverter leg. |
| Pin 2 (Tab) | Cathode | Output terminal and primary thermal interface; must be electrically isolated and thermally coupled to heatsink. |
Key Features
| Feature | Design Value |
|---|---|
| Hyper-fast soft recovery | 30ns tRR with low IRM (8.5A) and QRR (455nC) minimizes voltage spikes and EMI in CCM PFC. |
| Glass passivated die | Enhances long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in industrial environments. |
| RoHS-compliant & Halogen-free | Meets EU RoHS 3 (2015/863/EU); Br+Cl <1500ppm, Sb <1000ppm - supports "Green" manufacturing requirements. |
| AEC-Q101 ready | Manufactured in IATF 16949 certified facilities; PPAP-capable for automotive power modules requiring qualified change control. |
Applications
| Server Power Supply PFC Stage | Solar Microinverter DC Link |
|---|---|
Use Scenario: Boost converter operating in continuous conduction mode at 65–100kHz to correct input line current waveform. IC Role / Device Role / Timing Role: High-current freewheeling diode conducting during MOSFET off-time; handles 15A RMS current with minimal reverse recovery loss.

IC Role / Device Role / Timing Role: Bidirectional clamping and freewheeling path during PWM dead-time; blocks 600V DC bus with <45μA leakage at ambient temperature. Use Value: 4°C/W RθJC enables direct tab-mounting to aluminum housing, eliminating discrete heatsinks and reducing system BOM cost by $0.32/unit. |
| Industrial Motor Drive Brake Circuit | EV Onboard Charger Auxiliary Supply |
Use Scenario: Regenerative braking energy dissipation path using IGBT-clamped topology in 5–10kW servo drives.

IC Role / Device Role / Timing Role: High-efficiency output rectifier delivering low VF (2.1V @ 125°C) to minimize conduction loss in compact form factor. Use Value: 2.9V VF at 25°C and stable 2.1V at 125°C enable >89% efficiency at 3A load while meeting automotive thermal derating curves. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage hyper-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1506D | Same 600V/15A rating; tRR = 35ns, VF = 2.2V @ 15A/125°C; TO-220AC package with identical pinout. | Higher tRR increases switching loss in >80kHz PFC; slightly lower VF improves conduction efficiency at elevated temperature. | Prefer when thermal design prioritizes VF over tRR, or when STMicroelectronics supply chain alignment is required. |
| IXYS MUR1560CT | 600V/15A dual common-cathode configuration; tRR = 60ns, VF = 2.4V @ 15A/125°C; TO-220AB package with 3 pins. | Not pin-compatible; dual-diode layout suits bridge configurations but adds complexity for single-diode freewheeling use. | Select only if dual-diode topology is already implemented; avoid for direct DTH1506FP replacement due to pinout and recovery mismatch. |
Compared with STTH1506D and MUR1560CT, DTH1506FP offers the fastest recovery (30ns) and highest temperature-rated leakage stability, making it optimal for high-frequency, low-EMI CCM PFC where switching loss dominates total loss budget.

FAQ
What is the maximum junction temperature and how is it related to case temperature?
The DTH1506FP has an operating junction temperature range of –55°C to +150°C. Its 15A average current rating is specified at TC = +90°C, meaning the case (tab) temperature must not exceed this value under continuous load. With RθJC = 4°C/W, a 30W power dissipation yields a 120°C junction rise above case, requiring careful heatsink design to keep TJ ≤150°C.
Is DTH1506FP qualified for automotive applications?
DTH1506FP is manufactured in IATF 16949 certified facilities and supports PPAP documentation. While not pre-qualified to AEC-Q101 in standard form, Diodes Incorporated offers AEC-Q101 qualification upon request with controlled change management-making it suitable for automotive onboard chargers, DC-DC converters, and body control modules where reliability and traceability are mandatory.
How does the soft recovery characteristic affect EMI performance?
The soft reverse recovery of DTH1506FP limits di/dt during turn-off, reducing high-frequency ringing and conducted EMI in the 30–150MHz band. Measured QRR of 455nC at 125°C and low IRM (8.5A) suppress voltage overshoot across switching devices, easing filter design and helping meet CISPR-22 Class B emissions limits without additional snubbers.
Can DTH1506FP replace standard ultrafast diodes like UF1506 in existing designs?
Yes, DTH1506FP is a direct drop-in replacement for UF1506 in ITO-220AC packages, offering superior tRR (30ns vs. 50ns), lower QRR, and improved thermal resistance (4°C/W vs. 5.5°C/W). No layout changes are needed, but designers should verify reduced voltage overshoot enables snubber simplification or higher switching frequency operation.
