Product details
Overview
APT60D60SG from Microsemi is an ultrafast soft recovery rectifier diode rated for 600 V reverse voltage and 60 A average forward current in TO-247 package, featuring 1.8 V typical forward voltage at 60 A, 120 ns reverse recovery time at 25°C, and low leakage (250 µA max at 600 V), used as anti-parallel diode in industrial inverters and motor controllers.
For engineers reviewing the APT60D60SG datasheet, APT60D60SG pinout, APT60D60SG application, or APT60D60SG equivalent, key selection criteria include soft recovery behavior, thermal resistance (0.34 °C/W junction-to-case), RoHS-compliant lead finish, and suitability for high-frequency switching in PFC and snubber circuits.
Technical Context
This diode employs a soft-recovery silicon epitaxial structure optimized to minimize voltage overshoot and EMI during turn-off, with reverse recovery charge (Qrr) of 0.211 µC at 125°C and 60 A. Its dynamic performance is characterized under controlled di/dt conditions (–200 A/µs) and specified across –55°C to +175°C operating range.
The device supports high-power density designs via low conduction loss (VF = 1.8 V typ @ 60 A) and efficient thermal dissipation enabled by low RθJC (0.34 °C/W) and copper-plated TO-247 heat sink interface. Junction capacitance is 90 pF at VR = 200 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Reverse Voltage | 600 V - supports DC bus operation in 400 VAC input inverters without derating |
| Avg Forward Current | 60 A @ TC = 135°C, 50% duty - enables continuous conduction in 5 kW+ power stages |
| Forward Voltage | 1.8 V typ @ IF = 60 A - reduces conduction loss to ~108 W per device at full load |
| Reverse Recovery Time | 120 ns @ IF = 60 A, diF/dt = –200 A/µs, TC = 25°C - limits switching loss and EMI in 20–50 kHz converters |
| Junction Capacitance | 90 pF @ VR = 200 V - minimizes capacitive coupling in high dv/dt gate drive environments |
| Thermal Resistance | 0.34 °C/W junction-to-case - allows direct mounting to heatsink for stable TJ < 150°C at 60 A |
| Leakage Current | 250 µA max @ VR = 600 V, 25°C - ensures low standby loss in offline PFC stages |
Pinout & Package
APT60D60SG uses the industry-standard TO-247 package with isolated metal tab (cathode-connected heat sink). Mounting torque: 1.1 N·m max. Package weight: 5.9 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Cathode | High-side return path | Connected to heatsink; must be electrically isolated from system ground unless referenced |
| 2 - Anode | Low-side switching node | Interfaces directly with IGBT/MOSFET emitter/source in anti-parallel configuration |
Key Features
| Feature | Design Value |
|---|---|
| Soft recovery waveform | Gradual current decay reduces voltage spikes and EMI vs. fast-recovery alternatives |
| Ultrafast trr | 120 ns enables use in 20–100 kHz SMPS and motor drives without snubber penalties |
| Low VF at high IF | 1.8 V @ 60 A cuts conduction loss by ~15% versus comparable 600 V diodes with VF > 2.0 V |
| RoHS-compliant finish | e3 termination (100% Sn) ensures lead-free assembly compatibility and solder joint reliability |

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 |
|---|---|---|---|
| STTH60R06DJF | 600 V / 60 A, 110 ns trr, VF = 1.75 V @ 60 A, TO-247, non-RoHS lead finish | Slightly faster recovery but higher EMI risk; no Pb-free option | Prefer when lowest VF dominates and RoHS not required |
| IXYS MDD60-16N1 | 600 V / 60 A, 140 ns trr, VF = 1.85 V @ 60 A, TO-247, RoHS-compliant | Softer recovery than STTH part but slower than APT60D60SG; higher VF | Prefer when EMI sensitivity is critical and moderate VF penalty acceptable |
Compared with STTH60R06DJF and IXYS MDD60-16N1, the APT60D60SG offers balanced softness (120 ns trr), low VF (1.8 V), and guaranteed RoHS compliance-making it optimal for noise-sensitive industrial inverters where both efficiency and EMI margin matter.

FAQ
What is the maximum junction temperature rating for APT60D60SG?
The APT60D60SG has a maximum junction temperature (TJ) rating of +175°C, verified per its absolute maximum ratings table. This allows operation in high-ambient industrial environments when properly heatsinked. The device's thermal resistance (RθJC = 0.34 °C/W) enables stable junction temperatures below 150°C at 60 A average current with adequate heatsinking. Derating curves in Figure 7 confirm usable current capability up to 135°C case temperature.
Is APT60D60SG pin-compatible with APT60D60BG?
Yes, APT60D60SG is pin-compatible with APT60D60BG - both share identical TO-247 package outline, terminal assignments (Pin 1 = Cathode, Pin 2 = Anode), and mechanical mounting dimensions. The only difference is the terminal finish: "G" denotes RoHS-compliant 100% Sn plating, while "B" uses standard SnPb. No PCB layout change is needed when substituting APT60D60SG for APT60D60BG in new designs.
What is the reverse recovery charge (Qrr) of APT60D60SG at 125°C?
The APT60D60SG specifies a typical reverse recovery charge (Qrr) of 0.211 µC at TJ = 125°C, IF = 60 A, diF/dt = –200 A/µs, and VR = 400 V. This value is measured under standardized test conditions and appears in the Dynamic Characteristics table of the official datasheet (053-6001 Rev I). Qrr increases with temperature and di/dt, so design margins should account for worst-case conditions in high-temp environments.
Can APT60D60SG be used in surface-mount designs?
No, APT60D60SG is packaged exclusively in TO-247 (through-hole) configuration. While the datasheet references a D3PAK variant (APT60D60S), the "G" suffix in APT60D60SG explicitly ties it to the TO-247 package with RoHS-compliant finish. For surface-mount applications, engineers should select APT60D60SG's sibling part APT60D60SG-D3PAK (if available) or verify alternate part numbers with D3PAK packaging and matching electrical specs.
Does APT60D60SG require a heatsink in all applications?
Yes, APT60D60SG requires a heatsink in any application operating above ~10 A average current due to its power dissipation profile. At 60 A and 1.8 V VF, conduction loss reaches ~108 W - far exceeding its ability to self-cool. The datasheet specifies RθJA = 40 °C/W (unmounted), meaning junction temperature would exceed 175°C within seconds without heatsinking. Proper mounting to a thermally rated heatsink (using recommended 1.1 N·m torque) is mandatory for rated current operation.
