Product details

Overview

APT20M16LFLLG from Advanced Power Technology is a 200V, 100A N-channel enhancement-mode Power MOSFET in TO-264 (LFLL) package, featuring 16 mΩ R_DS(on) at V_GS = 10V, fast body diode (t_rr = 230 ns), and low Q_g = 140 nC - designed for high-efficiency DC-DC converters and motor drive half-bridges.

For engineers reviewing the APT20M16LFLLG datasheet, APT20M16LFLLG pinout, APT20M16LFLLG application, or APT20M16LFLLG equivalent, key selection criteria include its 200V V_DSS, 100A I_D rating at T_C = 25°C, 0.18°C/W R_θJC, fast recovery diode (Q_rr = 450 µC), and T-MAX™-compatible TO-264 thermal performance.

Technical Context

This device implements APT's patented metal-gate structure to reduce Miller capacitance (C_rss = 145 pF) and gate charge while maintaining robust avalanche capability (E_AS = 300 mJ). Its FREDFET architecture integrates a fast, soft-recovery body diode optimized for synchronous rectification and ZVS circuits.

The APT20M16LFLLG operates with V_GS(th) = 3–5 V and supports gate drive voltages up to ±30 V. Thermal design leverages direct case-to-heatsink conduction via the TO-264 drain-tab footprint, enabling high-power switching at junction temperatures up to 150°C.

Parameter	Value and Actual Design Meaning
V_DSS	200 V - supports 170 V DC bus designs with 15% margin for voltage transients
R_DS(on)	0.016 Ω @ V_GS = 10 V - enables <1.6 W conduction loss at 100 A continuous current
I_D	100 A @ T_C = 25°C - rated for high-current half-bridge legs in industrial inverters
Q_g	140 nC - reduces gate driver power requirement and improves switching efficiency
t_rr	230 ns @ T_J = 25°C - minimizes reverse recovery losses in hard-switched topologies
R_θJC	0.18 °C/W - allows >380 W power dissipation with 65°C temperature rise across heatsink interface
E_AS	300 mJ - provides ruggedness against inductive switching stress without external snubbers

Pinout & Package

APT20M16LFLLG uses the TO-264 (LFLL) package - a variant of TO-247 with extended leadframe and no mounting hole, optimized for high-current PCB mounting and thermal transfer through the exposed drain tab.

FAQ

What is the maximum continuous drain current rating for APT20M16LFLLG?

The APT20M16LFLLG is rated for 100 A continuous drain current at case temperature T_C = 25°C. At elevated case temperatures, current must be linearly derated using the 5.56 W/°C derating factor and 0.18°C/W thermal resistance. Full 100 A operation requires effective heatsinking to maintain T_C ≤ 25°C.

Does APT20M16LFLLG have an integrated fast-recovery body diode?

Yes, the APT20M16LFLLG incorporates a FAST RECOVERY BODY DIODE with t_rr = 230 ns (T_J = 25°C) and Q_rr = 450 µC (T_J = 125°C). This FREDFET structure is explicitly characterized in the datasheet and enables synchronous rectification without external diodes in resonant and soft-switching topologies.

What package type does APT20M16LFLLG use, and how does it differ from standard TO-247?

The APT20M16LFLLG uses the TO-264 (LFLL) package - a variant of TO-247 with identical leadframe geometry but no mounting hole. Its dimensions match TO-247 for PCB compatibility, yet the extended drain tab improves thermal conduction and current-carrying capacity. The "LFLL" suffix denotes this specific outline per APT's packaging nomenclature.

What is the gate threshold voltage range for APT20M16LFLLG?

The APT20M16LFLLG has a gate threshold voltage V_GS(th) of 3.0 V (min) to 5.0 V (max) at I_D = 2.5 mA. This range ensures reliable turn-on with standard 10 V gate drivers while maintaining noise immunity in electrically noisy industrial environments.

Is APT20M16LFLLG suitable for avalanche-rated applications?

Yes, the APT20M16LFLLG is fully rated for repetitive avalanche operation with E_AS = 300 mJ (single-pulse) and I_AR = 100 A. These values are tested per MIL-STD-750 Method 3471 and validated across the full –55°C to +150°C junction temperature range, making it suitable for inductive load switching without external protection.
