Product details
Overview
60APU02 from Vishay Semiconductors is a 200 V, 60 A ultrafast soft recovery diode in TO-247AC package, optimized for high-frequency power converters and HF welding where low switching losses and EMI reduction are critical. It features 35 ns reverse recovery time (trr), 0.98 V typical forward voltage at 60 A and 25 °C, and 175 °C maximum junction temperature.
For engineers reviewing the 60APU02 datasheet, 60APU02 pinout, 60APU02 application, or 60APU02 equivalent, key selection criteria include soft recovery behavior, thermal resistance (RthJC = 0.70 K/W), junction capacitance (87 pF at 200 V), peak recovery current (4 A at 25 °C), and suitability for snubberless operation in industrial-grade SMPS and inverters.
Technical Context
The 60APU02 employs FRED Pt® (Fast Recovery Epitaxial Diode) silicon technology with soft reverse recovery characteristics, minimizing dI/dt-induced voltage spikes and RFI generation. Its trr remains stable across temperature and load-28 ns at 60 A/160 V/25 °C and 50 ns at 125 °C-enabling reliable operation in hard-switched topologies up to 20 kHz.
Designed for industrial-level qualification, it supports continuous forward current of 60 A at TC = 127 °C and withstands 800 A non-repetitive surge (IFSM). The TO-247AC package provides low thermal resistance and mechanical robustness for heatsink-mounted power stage designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 200 V blocking voltage - ensures safe operation in 160 V DC bus systems with margin |
| IF(AV) | 60 A average forward current at TC = 127 °C - defines continuous conduction capability with standard heatsinking |
| trr | 35 ns max at IF = 1 A, dIF/dt = 200 A/μs - enables high-frequency switching with minimal tail current loss |
| VF | 0.98 V typ at IF = 60 A, TJ = 25 °C - reduces conduction loss in high-current rectification stages |
| RthJC | 0.70 K/W - allows efficient heat transfer to heatsink, supporting >100 W dissipation at ΔT = 70 K |
| Qrr | 59 nC typ at TJ = 25 °C - quantifies stored charge contributing to turn-off loss and EMI |
| TJ max | 175 °C - permits operation in harsh industrial environments without derating below 125 °C ambient |
Pinout & Package
60APU02 uses the TO-247AC package with three terminals: anode (pin 1), cathode (pin 2), and isolated metal tab (pin 3, electrically connected to cathode). The package features a modified leadframe for improved thermal performance and mechanical stability under high-current cycling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Forward current entry point | Connected to AC or switching node side; must handle full 60 A RMS and 800 A surge |
| 2 (Cathode) | Forward current exit / reverse blocking terminal | Electrically tied to metal tab; serves as main output and heatsink interface |
| 3 (Tab) | Cathode connection and thermal path | Isolated mounting surface requiring insulating washer if heatsink is grounded |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | trr ≤ 35 ns with smooth IRRM decay - eliminates need for snubbers in most 20 kHz converters |
| High-temperature operation | Rated to 175 °C TJ - enables compact thermal design without forced air in industrial enclosures |
| Low forward voltage | VF = 0.98 V typ at 60 A - cuts conduction loss by ~15% vs. standard FRDs with VF > 1.15 V |
| Industrial qualification | Qualified per AEC-Q101 stress test conditions - suitable for long-life embedded power supplies |
| Low junction capacitance | CT = 87 pF at VR = 200 V - minimizes capacitive coupling noise in high-dV/dt gate drive environments |

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 |
|---|---|---|---|
| Vishay VS-60EPU02 | TO-247AC (unmodified) package; identical electrical specs but higher RthJC (0.75 K/W) and no isolated tab | Suitable for PCB-mount designs where tab isolation is unnecessary; less optimal for direct heatsink mounting | Select 60APU02 when cathode-tab isolation and lowest thermal resistance are required |
| IXYS MBR60200PT | Same 200 V/60 A rating but Schottky architecture; VF = 0.92 V typ but VR limited to 200 V with higher IR at TJ > 125 °C | Better conduction loss at low TJ; unsuitable above 150 °C due to exponential IR increase and lack of soft recovery | Choose 60APU02 for high-TJ, high-dV/dt, or snubberless designs where soft recovery is mandatory |
Compared with VS-60EPU02 and MBR60200PT, the 60APU02 delivers superior thermal performance via its modified TO-247AC tab design and maintains soft recovery integrity up to 175 °C-critical for unventilated industrial enclosures and high-reliability motor drives.

FAQ
What is the maximum junction temperature rating for the 60APU02?
The 60APU02 has a maximum rated junction temperature of 175 °C, verified per Vishay's industrial qualification standards. This allows sustained operation in high-ambient environments such as enclosed motor drives or welders without active cooling. Derating begins above 127 °C case temperature, and the device maintains full 60 A IF(AV) capability up to that point. Thermal design must account for RthJC = 0.70 K/W to ensure TJ stays within limit under worst-case load and ambient conditions. The 60APU02 datasheet specifies this rating across all test conditions in Document Number 93019.
Does the 60APU02 require a snubber circuit in typical power converter applications?
No, the 60APU02 does not require a snubber circuit in most high-frequency power converter applications due to its soft reverse recovery characteristic and low Qrr (59 nC typ). The gradual current decay during trr suppresses voltage overshoot caused by transformer or stray inductance. Vishay explicitly states in the Applications section that "the softness of the recovery eliminates the need for a snubber in most applications." This behavior is confirmed by measured trr waveforms showing controlled IRRM decay, making the 60APU02 ideal for snubberless PFC and inverter designs.
How does the TO-247AC modified package of the 60APU02 differ from the standard TO-247AC used in the 60EPU02?
The 60APU02 uses a TO-247AC modified package with an electrically isolated metal tab connected to the cathode, whereas the 60EPU02 uses the standard TO-247AC with non-isolated tab. This modification enables direct heatsink mounting without additional insulation when the cathode is referenced to chassis ground. The 60APU02 also achieves lower thermal resistance (RthJC = 0.70 K/W vs. 0.75 K/W for 60EPU02), improving power dissipation efficiency. Both share identical pinout (anode-pin1, cathode-pin2, tab-pin3), but only the 60APU02 supports isolated thermal mounting per Vishay Doc. 95253.
What is the reverse recovery time (trr) of the 60APU02 under full-load conditions?
The 60APU02 exhibits a reverse recovery time of 28 ns typical at IF = 60 A, dIF/dt = 200 A/μs, VR = 160 V, and TJ = 25 °C. At elevated temperature (TJ = 125 °C), trr increases to 50 ns under the same electrical conditions. These values are measured per JEDEC-standard test circuit (Fig. 9 in Doc. 93019) and reflect real-world performance in hard-switched converters. The 60APU02 maintains sub-35 ns trr at light loads (IF = 1 A), confirming its ultrafast classification across operating range.
Can the 60APU02 be used as a direct replacement for the 60EPU02 in existing designs?
The 60APU02 is not a direct pin-compatible replacement for the 60EPU02 due to differences in package construction: the 60APU02 uses TO-247AC modified with isolated cathode tab, while the 60EPU02 uses standard TO-247AC with non-isolated tab. Although both share identical pin numbering and electrical specifications, mechanical mounting and thermal interface requirements differ. Replacing 60EPU02 with 60APU02 requires verification of heatsink isolation and may necessitate layout changes to accommodate the modified tab structure. Always consult Vishay Doc. 95253 before substitution.
