STMicroelectronics STL16N60M6

Overview

STL16N60M6 from STMicroelectronics is an N-channel 600 V, 0.35 Ω max, 8 A Power MOSFET using MDmesh™ M6 superjunction technology in a PowerFLAT™ 5x6 HV package. It delivers low conduction loss, high dv/dt ruggedness (50 V/ns), and 100% avalanche tested reliability for offline SMPS, PFC stages, and industrial motor drives.

For engineers reviewing the STL16N60M6 datasheet, STL16N60M6 pinout, STL16N60M6 application, or STL16N60M6 equivalent, key selection criteria include R_DS(on) at 10 V gate drive, 2.4 °C/W junction-to-case thermal resistance, unclamped inductive switching capability, and Zener-protected gate robustness under transient conditions.

Technical Context

This MOSFET employs ST's MDmesh™ M6 silicon architecture, optimized for high-voltage switching with reduced R_DS(on) × area and improved E_AS (110 mJ). Its 50 V/ns MOSFET dv/dt ruggedness and 15 V/ns diode recovery dv/dt rating enable stable operation in hard-switched converters without snubber dependency.

The device integrates a monolithic Zener-protected gate structure and features low intrinsic gate resistance (5.2 Ω) and tightly controlled Q_gd/Q_gs ratio (9.4 nC / 3.5 nC), supporting clean turn-off and reduced Miller-induced shoot-through risk in half-bridge topologies.

Key Specifications

FAQ

What is the maximum allowable gate-source voltage for STL16N60M6?

The absolute maximum gate-source voltage is ±25 V, as specified in Table 2 of the datasheet. This limit is enforced by the integrated Zener diode between gate and source, which clamps transients beyond this range. Operation above ±25 V risks permanent gate oxide damage, even with short-duration spikes.

Can STL16N60M6 be used in synchronous rectification configurations?

Yes-its body diode exhibits low forward voltage (1.6 V at 8 A) and fast reverse recovery (210 ns at 12 A, 100 A/µs), enabling use in secondary-side synchronous rectification of flyback and LLC converters. However, external control logic is required since the device lacks integrated gate driver or sensing circuitry.

How does the PowerFLAT™ 5x6 HV package affect thermal design?

The package provides 2.4 °C/W junction-to-case thermal resistance when soldered to a 1-inch² FR-4 board with 2 oz copper. Its exposed drain pad must be fully soldered to a large copper pour or thermal pad; insufficient solder coverage increases R_thj-pcb from 50 °C/W to >80 °C/W, risking thermal runaway at rated current.

Is avalanche energy rating guaranteed per unit or batch?

The 110 mJ single-pulse avalanche energy (E_AS) is a guaranteed minimum parameter verified on 100% of units during production test. Each device undergoes unclamped inductive switching stress at I_AR = 2.5 A and V_DD = 50 V, with junction temperature monitored to ensure compliance with the specified E_AS limit.
