Product details
Overview
DTH1206FP from Diodes Incorporated is a 12A, 600V hyper-fast epitaxial rectifier diode in ITO-220AC package, featuring 30ns reverse recovery time, 2.4–2.9V forward voltage at 12A, and 45µA reverse leakage at 600V/25°C; used in snubber circuits, PFC stages, and motor drive demagnetization paths.
For engineers reviewing the DTH1206FP datasheet, DTH1206FP pinout, DTH1206FP application, or DTH1206FP equivalent, key selection criteria include soft recovery behavior, continuous conduction mode (CCM) PFC suitability, thermal resistance (RθJC = 4°C/W), and ITO-220AC mounting compatibility with heatsink interfaces.
Technical Context
This hyper-fast rectifier employs epitaxial construction with glass passivation to achieve soft reverse recovery-critical for minimizing EMI in high-frequency switching converters. Its 30ns tRR and low stored charge support operation in CCM boost PFC topologies up to 100kHz without excessive switching loss.
The device is rated for 12A average forward current with 120A non-repetitive surge capability (8.3ms half-sine), and features RθJC = 4°C/W and RθJL = 5°C/W-enabling direct case-to-heatsink thermal coupling in industrial power supplies and motor control inverters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum blocking voltage before avalanche; supports 400V DC bus designs with 50% safety margin. |
| IO | 12 A - Continuous average forward current at TA = 25°C; derates to ~7.5A at TC = 100°C per curve. |
| tRR | 30 ns - Measured at IF = 0.5A, IR = 1.0A, IRR = 0.25A; enables soft switching in 50–100kHz PFC stages. |
| VF | 2.4–2.9 V @ 12A - Forward drop impacts conduction loss; 2.9V max at 25°C implies ~35W dissipation at full load. |
| IR | 45 µA @ 600V/25°C - Low leakage preserves efficiency in high-impedance snubber networks. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance allows direct heatsink mounting without thermal interface pads in many applications. |
Pinout & Package
Package: ITO-220AC (Type WX-NC), molded plastic with matte tin–annealed copper leadframe, UL 94V-0 rated, 1.5g weight. Polarity: Anode and Cathode marked on top surface; cathode indicated by green band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Lead) | Anode | Main current entry point; electrically connected to die anode and metal tab (case). |
| Pin 2 (Tab) | Cathode | Primary cathode terminal; electrically isolated from mounting surface but serves as main cathode connection. |
| Pin 3 (Lead) | Cathode | Secondary cathode lead; provides low-inductance return path parallel to tab for high-dI/dt applications. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Industrial Power Supply Output Rectification | Motor Drive Demagnetization Clamp |
|---|---|
Use Scenario: High-efficiency 3kW AC-DC front-end with active PFC and LLC resonant secondary. IC Role / Device Role / Timing Role: Main output rectifier in synchronous rectified LLC secondary stage, handling 12A continuous DC output.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hyper-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1206D | Same 600V/12A rating; tRR = 35ns, VF = 2.7V typ @ 12A; RθJC = 4.5°C/W. | Slightly slower recovery increases EMI in >80kHz PFC; higher thermal resistance requires larger heatsink. | Preferred where ST ecosystem alignment or dual-sourcing is required; verify layout for added EMI filtering. |
| IXYS MUR1260CT | 600V/12A dual common-cathode; tRR = 60ns, VF = 2.2V typ; TO-220AB package, no isolated tab. | Not suitable for single-diode snubber or bootstrap roles; dual configuration fits bridge rectifiers only. | Only viable if redesigning for dual-diode topology and accepting 2× tRR penalty in high-frequency operation. |
Compared with STTH1206D and IXYS MUR1260CT, DTH1206FP delivers the fastest recovery (30ns), lowest thermal resistance (4°C/W), and ITO-220AC's isolated cathode tab-making it optimal for space-constrained, high-efficiency snubber and CCM PFC designs where thermal and EMI margins are tight.

FAQ
What is the maximum junction temperature for continuous operation?
The DTH1206FP has an operating junction temperature range of –55°C to +150°C. For reliable continuous operation at full 12A current, thermal design must ensure TJ remains ≤150°C-typically achieved with a heatsink maintaining TC ≤100°C given RθJC = 4°C/W and 2.9V VF.
Is the ITO-220AC package electrically isolated?
No-the ITO-220AC package has an electrically isolated cathode tab (Pin 2), but the anode (Pin 1) is connected to the metal tab. The third lead (Pin 3) is also cathode. This configuration enables flexible mounting: the tab can be heatsinked while maintaining cathode reference, unlike standard TO-220.
Does DTH1206FP meet AEC-Q101 requirements?
DTH1206FP is not AEC-Q101 qualified. Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing-customers needing automotive qualification must contact Diodes directly for designated AEC-Q101 variants such as DTH1206QFP.
How does its soft recovery reduce EMI in PFC circuits?
Soft recovery limits dV/dt during turn-off by controlling tail current decay rate. In CCM boost PFC, this suppresses high-frequency ringing caused by parasitic inductance interacting with abrupt current collapse-reducing conducted EMI by up to 8dB in 30–100MHz band compared to standard fast recovery diodes.
