Product details
Overview
APT30D60SG from Microsemi is a 600 V, 30 A fast soft recovery silicon rectifier diode in TO-247 package, engineered for high-efficiency PFC stages and inverter freewheeling paths where low noise and low switching loss are critical. It delivers VF = 1.6 V at 30 A (25 °C), trr = 23 ns at 1 A/–100 A/µs, Qrr = 130 nC, and RθJC = 0.67 °C/W.
For engineers reviewing the APT30D60SG datasheet, APT30D60SG pinout, APT30D60SG application, or APT30D60SG equivalent, key selection criteria include soft-recovery EMI performance, thermal resistance under high-duty-cycle conduction, reverse recovery charge trade-offs at elevated di/dt, and compatibility with 600 V system-level insulation requirements.
Technical Context
This diode employs optimized silicon junction design to achieve soft reverse recovery-minimizing voltage overshoot and dV/dt-induced ringing during turn-off. Its low Qrr and controlled IRRM support high-frequency operation up to 100 kHz in continuous conduction mode PFC.
The device operates across –55 °C to +175 °C junction temperature range with VRWM = 600 V and IFSM = 320 A (8.3 ms), enabling robust surge handling in motor drive snubber and anti-parallel configurations without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM / VRRM | 600 V - Supports 400 V AC input PFC front-ends with 1.5× safety margin against line transients. |
| IF(AV) @ TC=140°C | 30 A - Sustains continuous forward current in thermally constrained heatsink layouts. |
| VF @ 30 A, 25°C | 1.6 V - Reduces conduction loss to ≤48 W per device at full load, lowering thermal stress. |
| trr @ 1 A, –100 A/µs | 23 ns - Enables clean zero-current switching in high-frequency boost converters. |
| Qrr @ 30 A, –200 A/µs | 130 nC - Limits stored charge dissipation during commutation, reducing MOSFET turn-on loss. |
| RθJC | 0.67 °C/W - Allows direct mounting to aluminum heatsinks for <100 °C junction rise at 30 A DC. |
| IRM @ 600 V, 25°C | 250 µA - Ensures minimal leakage in high-impedance hold-up circuits and standby modes. |
Pinout & Package
APT30D60SG uses the industry-standard TO-247 (B) package with three terminals: anode (Terminal 2), cathode (Terminals 1 and 3). The dual-cathode configuration provides low-inductance parallel current paths and enhanced thermal spreading via the large metal tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (Cathode) | Main cathode connection | Primary current return path; electrically tied to metal tab for low-inductance grounding. |
| Terminal 2 (Anode) | Anode connection | Input node for forward conduction; isolated from tab for safe high-side placement. |
| Terminal 3 (Cathode) | Secondary cathode | Redundant cathode terminal enabling symmetrical PCB layout and reduced loop inductance in bridge legs. |
Key Features
| Feature | Design Value |
|---|---|
| Soft recovery waveform | Controlled IRRM ramp-down minimizes dI/dt-induced voltage spikes and EMI filter burden. |
| Low Qrr at high di/dt | 130 nC at –200 A/µs enables efficient synchronous rectification pairing in LLC resonant converters. |
| High TJ max rating | 175 °C junction limit supports operation in sealed industrial enclosures without forced air. |
| RoHS-compliant construction | Lead-free matte tin plating on leads and Pb-free die attach meet IPC/JEDEC J-STD-020D reflow profiles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast soft recovery diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MUR3060CT | TO-247 package, dual-die common-cathode; VF = 1.85 V @ 30 A, trr = 35 ns @ 1 A. | Higher VF increases conduction loss by ~7.5 W; longer trr raises EMI filtering requirement. | Preferred when cost sensitivity outweighs efficiency targets and layout allows larger heatsink. |
| Vishay VS-30CPH06 | TO-247AC package, single-anode dual-cathode; VF = 1.7 V @ 30 A, Qrr = 190 nC @ –200 A/µs. | Higher Qrr increases MOSFET turn-on loss in synchronous topologies; same thermal resistance. | Selected where legacy qualification or Vishay supply chain alignment drives sourcing decisions. |
Compared with MUR3060CT and VS-30CPH06, APT30D60SG offers the lowest combined Qrr–trr–VF product for high-frequency PFC and inverter freewheeling, delivering measurable reduction in system-level thermal load and EMI filter component count.

FAQ
What is the maximum junction temperature rating for APT30D60SG?
The APT30D60SG has a maximum junction temperature (TJ) rating of +175 °C, verified per Absolute Maximum Ratings table in the official datasheet. This allows operation in sealed enclosures or high-ambient environments without derating, provided case temperature remains ≤140 °C under 30 A average current. Thermal design must respect RθJC = 0.67 °C/W to maintain safe TJ margins.
Does APT30D60SG support RoHS compliance and lead-free assembly?
Yes, APT30D60SG is RoHS compliant and qualified for lead-free reflow soldering per IPC/JEDEC J-STD-020D. Its matte tin-plated leads and Pb-free die attach enable compatibility with standard peak reflow profiles up to 260 °C. Full material declarations and test reports are available through Microchip's component portal upon request for APT30D60SG.
How does the dual-cathode configuration of APT30D60SG improve circuit performance?
The dual-cathode (Terminals 1 and 3) configuration in APT30D60SG reduces package inductance and improves current sharing symmetry in bridge-leg layouts. It enables balanced PCB routing to minimize commutation loop area, directly lowering radiated EMI and voltage overshoot during fast di/dt transitions. This topology is especially beneficial in three-phase inverter outputs and interleaved PFC designs using APT30D60SG.
What is the reverse recovery charge (Qrr) of APT30D60SG under typical PFC operating conditions?
Under typical PFC conditions-30 A forward current, –200 A/µs diF/dt, and 400 V reverse voltage-the APT30D60SG exhibits Qrr = 130 nC (typical), as specified in Table 4 of the datasheet. At elevated junction temperature (125 °C), Qrr rises to 700 nC, which must be accounted for in MOSFET gate drive loss calculations and thermal modeling of the APT30D60SG in high-power designs.
Can APT30D60SG replace standard ultrafast diodes in existing 600 V designs without layout changes?
APT30D60SG uses the standard TO-247 footprint and pinout (anode on Terminal 2, cathodes on Terminals 1 and 3), making it a drop-in replacement for many TO-247 ultrafast diodes. However, its soft recovery behavior may alter snubber requirements and EMI filter tuning. System validation-including turn-on loss measurement and conducted emissions testing-is recommended before full deployment of APT30D60SG in legacy designs.
