Alpha & Omega Semiconductor Inc. AFP5D06K060Q5S

Overview

AFP5D06K060Q5S from Alpha and Omega Semiconductor is a dual-in-line intelligent power module integrating 600V/6A trench-shielded planar gate IGBTs, high- and low-side HVIC drivers, built-in bootstrap diodes with 100Ω current-limiting resistors, UVLO, OT monitoring (VOT), short-circuit protection (CSC), and controllable fault output (VCF) - designed for compact inverter stages in AC-fed motor drives.

For engineers reviewing the AFP5D06K060Q5S datasheet, pinout, applications, or equivalent options, key selection considerations include its IPM-5A package with 23-pin layout, 2000Vrms isolation rating, -40°C to 150°C operating junction temperature, and integrated protection logic requiring no external optocouplers for MCU-level PWM interfacing.

Technical Context

This module implements a full-bridge inverter topology with independent U- and W-phase outputs (pins 21 and 19), separate high-side bias supplies (VB(U), VB(W)), and six isolated input channels (IN(UH), IN(UL), IN(WH), IN(WL)) supporting 3–18V Schmitt-trigger logic. Protection functions are hardware-based: CSC detection uses an external RC filter on pin 13, VOT provides analog temperature voltage referenced to COM, and VCF delivers open-drain fault signaling with configurable pulse width via external R/C.

The internal architecture separates power and control domains: high-side IGBTs use floating HVIC drivers powered by VB(U)/VB(W), while low-side IGBTs share VDD and COM; thermal sensing relies on LVIC die temperature mapped to VOT output (0.77–2.55V over 25–80°C), and short-circuit protection is active only on low-side switches per datasheet specification.

Key Specifications

Pinout & Package

AFP5D06K060Q5S uses the IPM-5A package: 33.4 × 15 × 3.6 mm dual-in-line format with short pin length, RoHS-compliant, and UL recognized. Pin 15 (COM) is the primary control ground reference; pin 22 (P) and pins 16/18 (NW/NU) form the DC-link interface; pins 19 (W) and 21 (U) deliver phase outputs.

FAQ

What is the maximum allowable DC-link voltage for AFP5D06K060Q5S?

The AFP5D06K060Q5S supports a maximum DC-link supply voltage (VPN) of 450V under normal operation and 500V for non-repetitive surge conditions, as specified in Absolute Maximum Ratings on page 3. Operation above 400V requires verification of short-circuit protection capability (VPN(PROT) = 400V) and thermal derating per recommended operating conditions.

How does the VOT pin function in AFP5D06K060Q5S temperature monitoring?

The VOT pin on AFP5D06K060Q5S outputs an analog voltage (0.77–2.55V) linearly proportional to LVIC die temperature (25–80°C), with ±3.5°C accuracy. When left open, it enables both over-temperature protection and monitoring; with a 10kΩ pull-down, it disables protection and provides analog readout only - per Figure 4 and page 6 notes.

Can AFP5D06K060Q5S drive a three-phase motor directly?

No - AFP5D06K060Q5S integrates only U- and W-phase outputs (pins 21 and 19) and associated high-/low-side drivers; it lacks V-phase output and control channels. It is designed for two-phase or half-bridge configurations, not full three-phase motor drive. A second identical module or complementary part is required for full 3-phase control.

What is the purpose of the CSC pin on AFP5D06K060Q5S?

The CSC pin on AFP5D06K060Q5S receives a filtered voltage from an external shunt resistor to detect short-circuit events on low-side IGBTs. With a 0.48V threshold and RC time constant tuned per page 11 recommendation (#5), it triggers automatic shutdown within ≤2µs - a hardware-based protection that operates independently of MCU intervention.

Does AFP5D06K060Q5S require external bootstrap capacitors?

Yes - AFP5D06K060Q5S requires external bootstrap capacitors connected between VB(U)–U and VB(W)–W, as shown in the application circuit on page 11. The built-in bootstrap diodes (with 100Ω series resistance) charge these capacitors during low-side conduction; capacitor selection (e.g., C1 ≥10µF) must ensure sufficient hold-up during high-side duty cycles.
