Product details
Overview
APT75DQ100BG from Advanced Power Technology is an ultrafast soft recovery rectifier diode rated for 1000 V repetitive reverse voltage and 75 A average forward current at TC = 130°C, featuring low forward voltage (3.0 V typ. at 75 A), soft recovery characteristics, and avalanche energy rating (20 mJ). It serves as an anti-parallel or freewheeling diode in high-frequency switchmode power supplies and motor inverters.
For engineers reviewing the APT75DQ100BG datasheet, APT75DQ100BG pinout, APT75DQ100BG application, or APT75DQ100BG equivalent, key selection criteria include reverse recovery time (33 ns typ. at 25°C), junction-to-case thermal resistance (0.22 °C/W), RoHS-compliant Pb-free terminations, and TO-247 package compatibility with heatsink mounting.
Technical Context
This diode employs a planar epitaxial silicon structure optimized for ultrafast switching with soft reverse recovery-minimizing voltage overshoot and EMI in hard-switched topologies. Its 1000 V VRRM and 540 A IFSM support robust operation in 3-phase PFC and IGBT-clamped inverter legs.
Thermal performance is defined by a low RθJC of 0.22 °C/W and a wide operating junction temperature range of –55°C to +175°C, enabling reliable conduction under high-duty-cycle conditions in industrial motor drives and UPS systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum peak repetitive reverse voltage; defines safe blocking capability in 600–800 V DC bus applications. |
| IF(AV) | 75 A at TC = 130°C - Continuous forward current rating with 50% duty cycle; sets heatsink sizing baseline. |
| VF | 3.0 V typ. at IF = 75 A - Low conduction loss directly reduces power dissipation and improves system efficiency. |
| trr | 33 ns typ. at 25°C - Ultrafast recovery enables >100 kHz switching without excessive di/dt-induced stress on IGBTs. |
| EAVL | 20 mJ - Avalanche-rated energy absorption ensures ruggedness during transient overvoltage events. |
| RθJC | 0.22 °C/W - Enables direct heatsink mounting with minimal thermal interface resistance for compact thermal design. |
| Qrr | 250 nC typ. at 25°C - Low recovered charge reduces switching losses and snubber requirements in resonant converters. |
Pinout & Package
APT75DQ100BG uses the industry-standard TO-247 package with isolated metal tab (cathode) for direct heatsink mounting. The plastic body provides creepage/clearance compliance for 1000 V isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Cathode | High-side return path | Electrically connected to metal tab; must be insulated from heatsink unless referenced to system ground. |
| 2 - Anode | Low-side conduction terminal | Carries full forward current; requires low-inductance PCB trace routing to minimize ringing. |
Key Features
| Feature | Design Value |
|---|---|
| Soft recovery waveform | Minimizes voltage spikes and EMI generation during turn-off, reducing need for external snubbers in IGBT modules. |
| Avalanche energy rating | 20 mJ single-pulse capability allows safe operation under unclamped inductive switching stress. |
| RoHS-compliant terminations | e3 finish (100% Sn) ensures lead-free assembly compatibility and eliminates Pb-related reliability concerns. |
| Low leakage current | 100 μA max at 1000 V enables stable blocking in high-impedance gate drive or sensing circuits. |

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 |
|---|---|---|---|
| IXYS MUR75100CT | Higher VF (3.3 V typ.), higher trr (45 ns), same TO-247 package. | Suitable for lower-frequency (<50 kHz) designs where softness is less critical. | Prefer APT75DQ100BG when minimizing EMI or optimizing efficiency above 80 kHz. |
| Vishay VS-75E100 | Lower IF(AV) (60 A), no avalanche rating, identical VRRM and package. | Limited to non-critical freewheeling roles without transient overvoltage exposure. | Select APT75DQ100BG where system-level reliability demands avalanche ruggedness. |
Compared with MUR75100CT and VS-75E100, APT75DQ100BG delivers superior soft recovery behavior and verified avalanche capability-critical for high-reliability industrial inverters and PFC stages exposed to line transients.

FAQ
What is the maximum junction temperature rating for APT75DQ100BG?
The APT75DQ100BG has a specified operating junction temperature range of –55°C to +175°C. This wide range supports deployment in harsh environments such as industrial motor drives and outdoor renewable energy inverters. The 175°C upper limit allows full utilization of its 75 A average current rating even at elevated ambient temperatures when properly heatsinked.
Does APT75DQ100BG have avalanche capability, and how is it quantified?
Yes, APT75DQ100BG is avalanche energy rated at 20 mJ under specified test conditions (1 A, 40 mH inductive load). This rating is measured and guaranteed per datasheet Figure 10 test circuit, confirming its ability to absorb transient energy without failure-critical for protecting IGBTs during unclamped inductive switching events in motor control applications.
What is the thermal resistance from junction to case (RθJC) for APT75DQ100BG?
The junction-to-case thermal resistance of APT75DQ100BG is 0.22 °C/W (typical), measured under standard mounting conditions with thermal compound and 1.1 N·m torque. This low value enables efficient heat transfer to external heatsinks and is essential for maintaining safe junction temperatures under continuous 75 A conduction at TC = 130°C.
Is APT75DQ100BG compatible with lead-free reflow soldering processes?
Yes, APT75DQ100BG features e3 termination finish (100% tin), fully compliant with JEDEC J-STD-020 moisture sensitivity level 1 and RoHS Directive 2011/65/EU. Its maximum lead temperature rating of 300°C for 10 seconds supports standard Pb-free reflow profiles without compromising solder joint integrity or device reliability.
How does the soft recovery characteristic of APT75DQ100BG improve system-level EMI performance?
The soft recovery waveform of APT75DQ100BG reduces the rate of change of reverse current (di/dt) during turn-off, suppressing high-frequency voltage ringing across parasitic inductances. This directly lowers conducted and radiated EMI emissions-reducing filter component count and easing compliance with CISPR 11 Class A limits in industrial power converters.
