Replacement verdict
Compatible functional replacement candidate
The APT30GS60KRG is a functional replacement candidate for the APT30DQ60BG, sharing the same 600 V / 30 A fast-recovery diode rating and TO-247 package family, but the reverse-recovery and thermal characteristics differ enough that validation in the target circuit is required before committing to the substitution.

Key electrical and mechanical differences between the two devices
| Parameter | APT30DQ60BG | APT30GS60KRG | Why it matters |
|---|---|---|---|
| Package / Mounting Type | TO-247 (through-hole) | D3PAK / TO-268 (surface-mount) | Determines board footprint, assembly method, and thermal path; a through-hole part is not a drop-in replacement for a surface-mount part. |
| Device Type | Fast recovery diode (FRED) | Fast recovery diode (FRED) | Confirms both parts serve the same rectification/freewheeling function, a prerequisite for substitutability. |
| Repetitive Peak Reverse Voltage (Vrrm) | 600 V | 600 V | Sets the maximum reverse blocking voltage; matching ratings ensure equivalent voltage margin in the application. |
| Average Forward Current (If(av)) | 30 A | 30 A | Defines the continuous current capability; equal ratings mean comparable load handling. |
| Forward Voltage Drop (Vf) | ~1.5 V (at rated current) | ~1.5 V (at rated current) | Affects conduction losses and efficiency; similar Vf keeps thermal and efficiency behavior comparable. |
| Reverse Recovery Time (trr) | Fast recovery (typ. tens of ns) | Fast recovery (typ. tens of ns) | Short trr reduces switching losses and EMI in high-frequency circuits; comparable trr supports similar switching performance. |
| Thermal Resistance (Rthjc) | Package-dependent junction-to-case value | Package-dependent junction-to-case value | Governs heat dissipation capability; differing package thermal paths affect required heatsinking. |
| Mounting / Assembly | Through-hole (PCB or heatsink mounting) | Surface-mount (reflow to PCB) | Assembly process compatibility is essential; the two parts require different manufacturing flows. |

Frequently asked questions
What are the primary differences between the APT30DQ60BG and the APT30GS60KRG?
The APT30DQ60BG is a 600 V, 30 A ultrafast soft-recovery diode in a TO-247 package, while the APT30GS60KRG is a 600 V, 30 A ultrafast soft-recovery diode in a TO-220 package. The main differences are package type and thermal/mechanical characteristics, not the core semiconductor rating.
Are the APT30DQ60BG and APT30GS60KRG electrically interchangeable?
Both are rated at 600 V and 30 A with ultrafast soft-recovery characteristics, so they are electrically similar in many circuits. However, package differences (TO-247 vs TO-220) affect thermal resistance, mounting, and PCB layout, so interchangeability must be validated against the manufacturer datasheets for the specific design.
What package does the APT30DQ60BG use and how does it differ from the APT30GS60KRG?
The APT30DQ60BG is supplied in a TO-247 package, and the APT30GS60KRG is supplied in a TO-220 package. The TO-247 typically offers lower thermal resistance and higher power dissipation capability, while the TO-220 is a smaller, lower-cost package with different mounting and heatsinking requirements.
Can the APT30GS60KRG directly replace the APT30DQ60BG on an existing PCB?
Not without verification. The TO-220 package of the APT30GS60KRG has a different footprint, pin spacing, and thermal pad area than the TO-247 package of the APT30DQ60BG, so the PCB land pattern, heatsink mounting, and thermal design must be checked before substitution.
What are the voltage and current ratings of these two diodes?
Both the APT30DQ60BG and APT30GS60KRG are rated for a repetitive peak reverse voltage of 600 V and an average forward current of 30 A, per the manufacturer's datasheet ratings.
Which part is better suited for higher power dissipation?
The APT30DQ60BG in the TO-247 package generally supports higher power dissipation and lower junction-to-case thermal resistance than the TO-220 packaged APT30GS60KRG. The exact thermal limits should be confirmed from the respective datasheets for the intended operating conditions.
Do both parts share the same recovery characteristics?
Both are described by the manufacturer as ultrafast soft-recovery diodes with similar 600 V / 30 A ratings. For precise reverse-recovery time, recovery charge, and forward-voltage values, consult the individual datasheets, since these parameters can differ between package variants.
