Product details
Overview
DTH810FP from Diodes Incorporated is an 8A, 1000V hyper-fast epitaxial rectifier diode optimized for high-frequency switching in SMPS primary-side rectification and PFC stages. It delivers 2.0V max forward voltage at 8A/25°C, 85ns reverse recovery time, and 5μA max leakage at 1000V - enabling efficient operation in LED drivers, AC-DC adapters, and telecom power supplies.
For engineers reviewing the DTH810FP datasheet, DTH810FP pinout, DTH810FP application, or DTH810FP equivalent, key selection criteria include its ITO220AC package thermal resistance (5°C/W junction-to-case), soft recovery behavior for EMI reduction, and suitability for discontinuous conduction mode (DCM) and critical conduction mode (CrCM) topologies.
Technical Context
This hyper-fast rectifier employs epitaxial silicon construction with glass passivation to achieve soft reverse recovery and low stored charge. Its 65–85ns tRR (measured at VR=30V, IF=1A, dIF/dt=−50 to −100A/µs) supports high-frequency operation up to 100kHz+ in resonant and quasi-resonant converters.
The device is rated for 8A average output current at TC=+95°C and withstands 80A non-repetitive surge (10ms half-sine). Its 5°C/W RθJC enables direct mounting to heatsinks without thermal interface material in medium-power designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Blocks full-wave rectified 700VAC line inputs with safety margin |
| IO (TC=95°C) | 8 A - Sustains continuous DC output in 100–150W SMPS designs |
| VF (max) | 2.0 V @ 8A/25°C - Limits conduction loss to ≤16W at full load |
| tRR (typ) | 65 ns - Enables soft-switching in CrCM PFC and LLC resonant converters |
| IR (max) | 5 μA @ 1000V/25°C - Ensures minimal standby power loss in no-load conditions |
| RθJC | 5 °C/W - Allows 40°C temperature rise with 8W dissipation on standard fin heatsink |
Pinout & Package
Package: ITO220AC (Type WX), thermally enhanced 3-lead through-hole package with isolated tab (cathode-connected), matte tin-plated copper leadframe, UL 94V-0 molding compound, 1.522g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Anode connection | Primary current entry point; mounted to PCB trace or heatsink via insulated washer if cathode-tab isolation required |
| Pin 2 (Cathode) | Cathode connection | Output node for rectified DC; electrically tied to metal tab in standard configuration |
| Tab (Cathode) | Main cathode terminal & thermal path | Provides low-inductance, high-current cathode return and primary heat conduction path to heatsink |
Key Features
| Feature | Design Value |
|---|---|
| Soft, hyper-fast switching | 65–85ns tRR with low IRM (13A peak) minimizes switching noise and snubber losses |
| Glass passivated die | Enhances humidity resistance and long-term reliability under thermal cycling stress |
| Suited for DCM/CrCM | Controlled minority carrier lifetime enables zero-current switching in boundary-mode PFC |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and "Green" compliance (<900ppm Br/Cl, <1000ppm Sb) |
Applications
| LED Lighting Power Supply | Server AC-DC Adapter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R06D | 600V VRRM, 8A IO, 75ns tRR, TO-220AC package | Limited to 400VAC input systems; lower thermal resistance (4.5°C/W) | Select when system input voltage ≤600V and higher thermal performance is prioritized over voltage rating |
| IXYS MUR8100E | 1000V VRRM, 8A IO, 100ns tRR, TO-220AC package | Harder recovery increases EMI; higher VF (2.2V) raises conduction loss | Choose only if supply-chain availability of DTH810FP is constrained and EMI filtering can be increased |
Compared with STTH8R06D and MUR8100E, the DTH810FP uniquely balances 1000V blocking, soft 85ns recovery, and 2.0V VF - making it optimal for CrCM PFC and high-density telecom rectifiers where voltage margin, EMI, and thermal design co-constrain selection.

FAQ
What is the maximum junction temperature for continuous operation?
The DTH810FP has an operating junction temperature range of −55°C to +150°C. For continuous 8A operation, case temperature must be maintained at or below +95°C per the derating curve - requiring heatsinking capable of dissipating ≥16W with ≤40°C rise above ambient.
Is the metal tab electrically isolated from the leads?
No - the ITO220AC tab is internally connected to Pin 2 (cathode) and forms the main cathode terminal. Electrical isolation requires use of insulating hardware (e.g., shoulder washers) when mounting to grounded heatsinks.
How does the DTH810FP perform in critical conduction mode (CrCM) PFC?
Its controlled carrier lifetime and soft recovery enable zero-current switching in CrCM boost PFC. Measured tRR of 65ns at −100A/µs dIF/dt ensures minimal voltage overshoot and reduced EMI generation during diode turn-off at light loads.
Does the DTH810FP meet automotive qualification standards?
No - the DTH810FP is not AEC-Q101 qualified. An automotive-compliant variant, DTH810FPQ, is available under a separate datasheet and undergoes additional stress testing per AEC requirements.
