Product details
Overview
HFA08TB60PBF from Infineon Technologies (formerly International Rectifier) is an ultrafast, soft-recovery silicon power diode rated for 600 V reverse voltage and 8 A continuous forward current in TO-220AC package. It delivers 65 nC reverse recovery charge, 240 A/µs peak di/dt during recovery, and 1.7 V max forward voltage at 8 A - enabling low-loss freewheeling and snubberless operation with IGBTs and MOSFETs in high-frequency inverters and motor drives.
For engineers reviewing the HFA08TB60PBF datasheet, HFA08TB60PBF pinout, HFA08TB60PBF application, or HFA08TB60PBF equivalent, key selection criteria include soft recovery behavior, Qrr < 70 nC at 25°C, trr ≤ 18 ns, IRRM ≤ 5.0 A, and thermal resistance RθJC = 3.5 °C/W - all critical for minimizing switching loss and EMI in hard-switched SMPS and industrial drive stages.
Technical Context
This diode employs epitaxial construction and optimized lifetime control to achieve ultra-soft reverse recovery with negligible snap-off, suppressing voltage overshoot and reducing RFI generation. Its low Qrr and controlled di(rec)M/dt minimize energy dissipation in both itself and the commutating switch.
The device is characterized across temperature (–55°C to +150°C TJ), with specified dynamic parameters at both 25°C and 125°C, including Qrr up to 360 nC and IRRM up to 8.0 A at elevated junction temperature - supporting robust design in thermally demanding motor control and UPS applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max) | 600 V - blocks line transients and DC bus spikes in 400 V AC-input PFC and 600 V DC-link inverters |
| IF (Cont, TC=100°C) | 8.0 A - supports continuous conduction mode operation in 500–800 W power stages without forced cooling |
| VFM (Max) | 1.7 V @ 8 A, 25°C - limits forward conduction loss to ≤13.6 W at full load, easing thermal design |
| Qrr (Typ) | 65 nC @ 25°C - reduces stored-charge-induced turn-on loss in synchronous rectifiers and IGBT clamps |
| di(rec)M/dt (Max) | 240 A/µs @ 25°C - enables controlled, low-EMI commutation without external snubbers |
| RθJC | 3.5 °C/W - allows direct mounting to heatsink for ≤30 K rise at 14 W dissipation (TC = 100°C rating) |
| trr (Typ) | 18 ns @ 1 A, 200 A/µs - ensures clean zero-current switching in 100–200 kHz hard-switched topologies |
Pinout & Package

IC Role / Device Role / Timing Role: Anti-parallel diode across MOSFETs in H-bridge output stage; conducts reactive current during grid synchronization. Use Value: IRRM ≤ 5.0 A at 25°C and ≤ 8.0 A at 125°C ensures stable operation under high ambient + solar heating, preventing thermal runaway. | Use Scenario: 1U server PSU with interleaved LLC + synchronous rectification, operating at 300–500 kHz. IC Role / Device Role / Timing Role: Secondary-side freewheeling diode in active clamp forward or asymmetrical half-bridge converter.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast soft-recovery diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R06DJF | 600 V, 8 A, Qrr = 72 nC (typ), trr = 25 ns, RθJC = 3.0 °C/W | Higher Qrr increases IGBT turn-on loss by ~12% in 100 kHz motor drive; lower RθJC allows marginally higher power density | Prefer when thermal budget is tighter but EMI constraints are relaxed |
| IXYS MUR860E | 600 V, 8 A, Qrr = 110 nC (typ), trr = 35 ns, softness not specified | Harder recovery increases voltage overshoot >15% in same layout; requires RC snubber adding 2 components and 0.5 W loss | Acceptable only in cost-sensitive, lower-frequency (<50 kHz) designs where EMI is filtered externally |
Compared with STTH8R06DJF and IXYS MUR860E, the HFA08TB60PBF offers the lowest Qrr and softest recovery among 8 A/600 V TO-220AC diodes, delivering measurable reductions in snubber loss, heatsink size, and EMC filter complexity - especially critical in space-constrained, high-density power modules.

FAQ
Is the HFA08TB60PBF pin-compatible with standard TO-220AC diodes?
Yes - it uses the industry-standard TO-220AC footprint with anode-connected tab, cathode on lead 1, and lead 2 unconnected. Mechanical dimensions match JEDEC TO-220AC specifications, enabling drop-in replacement in existing layouts provided thermal and electrical derating align with its 600 V/8 A ratings.
What is the maximum recommended mounting torque for the HFA08TB60PBF?
The datasheet specifies a mounting torque of 6.0 kg-cm (5.0 lbf·in) for the TO-220AC package. Exceeding this may deform the case or crack the internal die attach, increasing thermal resistance and risking premature failure under thermal cycling.
Does the HFA08TB60PBF require a thermal pad or insulator when mounted to a heatsink?
Yes - because the metal tab is electrically connected to the anode, an electrically isolating but thermally conductive pad (e.g., mica or ceramic) must be used unless the heatsink is fully floating or referenced to the anode potential in the circuit.
How does junction temperature affect reverse recovery performance?
At 125°C, Qrr increases to 124–360 nC (vs. 65–138 nC at 25°C) and IRRM rises to 4.5–8.0 A (vs. 3.5–5.0 A), directly increasing switching loss and voltage stress. Designers must use the 125°C dynamic specs for worst-case thermal analysis in enclosed or high-ambient environments.
