Microchip Technology APT30D100BCAG

Overview

APT30D100BCAG from Advanced Power Technology is a dual ultrafast soft-recovery rectifier diode in TO-247 package, rated for 1000 V reverse voltage and 2 × 18 A average forward current (TC = 105°C), with 35 ns reverse recovery time (IF = 30 A, diF/dt = −200 A/µs, TC = 25°C), used as free-wheeling diodes in motor controllers and snubber diodes in inverters.

For engineers reviewing the APT30D100BCAG datasheet, APT30D100BCAG pinout, APT30D100BCAG application, or APT30D100BCAG equivalent, key selection criteria include soft recovery behavior, low Qrr (25 nC at IF = 30 A, diF/dt = −200 A/µs, TC = 25°C), low VF (1.9 V typ. at IF = 30 A), RoHS-compliant terminal finish, and common-anode dual configuration for compact half-bridge layouts.

Technical Context

This dual-diode device integrates two independent ultrafast soft-recovery rectifiers sharing a common anode terminal, enabling synchronous freewheeling or bidirectional clamping in DC-link and PFC stages. Its soft recovery minimizes EMI generation during turn-off, while low Qrr and IRRM reduce switching losses in high-frequency converters.

The device operates across −55°C to +175°C junction temperature range, with RθJC = 0.451 °C/W and maximum IFSM = 210 A (8.3 ms sine half-cycle), supporting robust thermal management in industrial motor drives and solar inverters where transient overcurrent resilience is critical.

FAQ

What is the maximum junction temperature rating for APT30D100BCAG?

The APT30D100BCAG 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 solar inverters. The device maintains full electrical specifications-including trr, Qrr, and VF-up to 150°C junction, with derating applied beyond that point per the thermal impedance curves in the official datasheet revision A.

Is APT30D100BCAG pin-compatible with other TO-247 dual diodes like STTH30L06D?

No, APT30D100BCAG is not pin-compatible with STTH30L06D. While both use TO-247 packages, APT30D100BCAG features a common-anode configuration (Pin 2 = Anode), whereas STTH30L06D is common-cathode (Pin 2 = Cathode). Swapping them without PCB revision would reverse polarity and cause immediate failure. Always verify pinout diagrams before substitution.

Does APT30D100BCAG require a thermal pad or insulator when mounted to a heatsink?

Yes-APT30D100BCAG's TO-247 metal tab is electrically connected to the anode (Pin 2), so an electrically isolating thermal pad or mica washer is required unless the heatsink is fully floating or referenced to the anode potential. Failure to isolate may cause short circuits in grounded-system topologies. Thermal interface material must also accommodate the 0.451 °C/W RθJC specification.

What is the reverse recovery charge Qrr of APT30D100BCAG under typical operating conditions?

The APT30D100BCAG specifies Qrr = 25 nC typical at IF = 30 A, diF/dt = −200 A/µs, VR = 667 V, and TC = 25°C. At TJ = 125°C, Qrr increases to 67 nC. These values directly impact snubber sizing and switching loss calculations in hard-switched converters-designers should use the 125°C value for worst-case thermal design.

How does the "G" suffix in APT30D100BCAG affect its compliance and assembly process?

The "G" suffix in APT30D100BCAG denotes RoHS compliance and a lead-free SAC (Sn-Ag-Cu) terminal finish. It meets JEDEC J-STD-020 moisture sensitivity level 1 and supports standard Pb-free reflow profiles (peak 260°C). No special assembly precautions beyond standard RoHS handling are required, and the device is compatible with no-clean fluxes and automated optical inspection.
