Product details
Overview
DSR8F600PI from Diodes Incorporated is a general-purpose silicon rectifier diode rated for 600V PIV and 8A average forward current in an ITO-220AC package, featuring low forward voltage drop (1.15V at 8A), soft recovery characteristics, and suitability for AC/DC input rectification in offline power supplies.
For engineers reviewing the DSR8F600PI datasheet, DSR8F600PI pinout, DSR8F600PI application, or DSR8F600PI equivalent, key selection criteria include peak repetitive reverse voltage, forward current derating at elevated case temperature, thermal resistance (RθJC = 1.8°C/W), and soft-recovery behavior for EMI-sensitive designs.
Technical Context
This device operates as a single-phase, unidirectional power rectifier with a maximum junction temperature of 175°C and a typical reverse recovery time (trr) of 2.5 µs at IF = 4A, TJ = 25°C. Its soft recovery profile minimizes switching noise during turn-off in bridge configurations.
The ITO-220AC package uses a metal tab for direct heatsinking without electrical isolation, requiring external insulation when mounted to grounded chassis. Thermal performance is validated under specified mounting conditions with 1.0 mm thick mica insulator and thermal grease.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Repetitive Reverse Voltage (VRRM) | 600 V - supports universal AC input (85–265 VAC) with ≥2× safety margin in bridge rectifiers |
| Average Forward Current (IF(AV)) | 8 A at TC = 110°C - defines continuous conduction capability with heatsink-limited case temperature |
| Forward Voltage Drop (VF) | 1.15 V at IF = 8A, TJ = 25°C - directly impacts conduction loss and thermal design in high-current paths |
| Reverse Recovery Time (trr) | 2.5 µs at IF = 4A, dI/dt = 100 A/µs, TJ = 25°C - enables lower EMI in 50/60 Hz and 100/120 Hz ripple applications |
| Thermal Resistance (RθJC) | 1.8 °C/W - quantifies junction-to-case heat transfer efficiency under standard mounting conditions |
| Maximum Junction Temperature (TJ) | 175 °C - sets upper limit for thermal design margin in sealed or high-ambient environments |
Pinout & Package
DSR8F600PI is housed in an ITO-220AC package with a non-isolated metal tab serving as the cathode terminal. The package requires mechanical fastening and thermal interface material for heatsink attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead) | Input current entry point | Connected to AC source or transformer secondary; must withstand full reverse voltage during off-state |
| Cathode (Tab) | Output current exit point | Electrically connected to metal tab; requires insulated mounting when chassis-grounded |
Key Features
| Feature | Design Value |
|---|---|
| Soft reverse recovery | Reduces high-frequency ringing and conducted EMI in bridge rectifier circuits without snubbers |
| High surge current rating (IFSM) | 120 A peak (half-sine, 8.3 ms) - withstands cold-start inrush in capacitor-input filters |
| Low leakage current (IR) | 5 µA max at 600 V, 25°C - maintains efficiency in high-impedance bias networks |
| Robust glass-passivated junction | Ensures long-term reliability under humidity and thermal cycling per JESD22-A108 |
Applications
| AC/DC Front-End Rectification | Industrial Power Supply Input Stage |
|---|---|
Use Scenario: Full-wave bridge rectification of 230 VAC mains in open-frame 100 W SMPS. IC Role / Device Role / Timing Role: Unidirectional current steering device converting AC input to pulsating DC prior to bulk capacitance. Use Value: 600 V rating provides 2.6× margin over peak line voltage (325 V), ensuring robustness against transients. | Use Scenario: Input rectification in DIN-rail mounted 24 V/10 A industrial power supply. IC Role / Device Role / Timing Role: High-current diode in discrete bridge configuration handling sustained 8 A load current. Use Value: 1.15 V VF limits conduction loss to ≤9.2 W at full load, easing thermal management. |
| UPS Battery Charger Input | LED Driver Bulk Rectification |
Use Scenario: AC input stage in online UPS charging circuit operating continuously at 6 A average. IC Role / Device Role / Timing Role: Main rectifier conducting during AC half-cycles; thermally coupled to shared heatsink. Use Value: RθJC = 1.8 °C/W enables stable operation at TC ≤ 110°C with minimal heatsink mass. | Use Scenario: Off-line LED driver with passive PFC delivering 40 W to constant-current string. IC Role / Device Role / Timing Role: Primary rectifier in voltage-doubler or bridge topology feeding bulk storage capacitor. Use Value: Soft recovery minimizes high-frequency noise coupling into sensitive analog current regulation circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R06DJF | 600 V, 8 A, TO-220AC, trr = 35 ns (fast recovery), VF = 1.7 V | Better suited for high-frequency switching where fast trr reduces switching loss | Select when operating above 20 kHz or minimizing reverse recovery charge is critical |
| ON Semiconductor MUR860E | 600 V, 8 A, TO-220AC, ultra-fast trr = 60 ns, VF = 1.85 V | Optimized for high-efficiency PFC stages with active switching control | Prefer for boost PFC rectifiers; avoid in low-frequency linear-regulated supplies due to higher VF |
Compared with STTH8R06DJF and MUR860E, DSR8F600PI trades faster recovery for lower conduction loss and softer switching noise-making it optimal for cost-sensitive, low-EMI 50/60 Hz rectification rather than high-frequency switching stages.

FAQ
Is DSR8F600PI electrically isolated from its metal tab?
No. The ITO-220AC package has a non-isolated metal tab that serves as the cathode terminal. Electrical isolation requires external insulation (e.g., mica washer and shoulder washer) when mounting to a grounded heatsink or chassis.
What is the maximum allowable case temperature for continuous 8 A operation?
The datasheet specifies IF(AV) = 8 A at TC = 110°C. Exceeding this case temperature requires derating per the published IF(AV) vs. TC curve, with zero current allowed above 175°C junction temperature.
Can DSR8F600PI replace a 1N5408 in a 12 V/3 A power supply?
Yes, but with caution: DSR8F600PI offers higher voltage rating (600 V vs. 1000 V for 1N5408) and higher current capacity (8 A vs. 3 A), yet its VF is slightly lower (1.15 V vs. ~1.2 V). Ensure mechanical fit and thermal design accommodate the ITO-220AC footprint and tab orientation.
Does DSR8F600PI meet JEDEC moisture sensitivity level (MSL) requirements for reflow soldering?
DSR8F600PI is not moisture-sensitive; it is a molded plastic discrete diode with no internal cavity or hygroscopic packaging. It does not require dry-packaging or bake-out prior to SMT assembly, though standard lead-free reflow profiles must respect its maximum lead temperature (260°C for 10 s).
