STMicroelectronics STY112N65M5

Overview

STY112N65M5 from STMicroelectronics is an N-channel 650 V, 96 A Power MOSFET in Max247 package, featuring 22 mΩ max R_DS(on), 350 nC total gate charge, and 100% avalanche-tested ruggedness. It leverages MDmesh M5 vertical process technology for high-efficiency switching in industrial SMPS and motor drives.

For engineers reviewing the STY112N65M5 datasheet, STY112N65M5 pinout, STY112N65M5 application, or STY112N65M5 equivalent, key selection criteria include its 650 V V_(BR)DSS, low 19 mΩ typ. R_DS(on), 15 V/ns dv/dt capability, and 2400 mJ E_AS - critical for hard-switched PFC and high-voltage DC-DC converters.

Technical Context

This MOSFET employs ST's MDmesh M5 silicon process, combining deep-trench vertical charge compensation with optimized PowerMESH layout to achieve ultra-low conduction loss while maintaining robust fast-recovery body diode performance (t_rr = 570 ns at 100 A/µs). Its 0.2 °C/W R_thJC enables high-power operation with minimal thermal derating.

The device supports high-speed switching with 267 ns voltage delay time (t_d(v)) and 118 nC Q_gd, enabling efficient operation in 100–300 kHz resonant and hard-switched topologies. Gate threshold voltage (3–5 V) ensures compatibility with standard 10 V gate drivers while avoiding spurious turn-on under noise.

Key Specifications

Pinout & Package

STY112N65M5 uses the Max247 package - a through-hole, isolated-tab TO-247 variant with enhanced thermal and creepage performance. The tab is electrically connected to the drain (D), supporting direct mounting to heatsinks with electrical isolation.

FAQ

What is the maximum continuous drain current at 100 °C case temperature?

The STY112N65M5 supports 61 A continuous drain current at T_C = 100 °C, as specified in Table 1 of DS6035 Rev 4. This derating reflects thermal limitations of the Max247 package and ensures safe operation within SOA boundaries at elevated ambient temperatures.

Does this MOSFET have an integrated body diode, and what are its key recovery characteristics?

Yes - it features a monolithic source-drain body diode with 570 ns reverse recovery time (t_rr) and 17 µC reverse recovery charge (Q_rr) at T_J = 25 °C. These values increase to 695 ns and 26 µC at 150 °C, confirming stable performance across full operating temperature range.

Can STY112N65M5 be used in parallel configurations, and what layout considerations apply?

Yes - its positive temperature coefficient of R_DS(on) (1.3× increase from −50 °C to 150 °C per Figure 10) enables stable current sharing. Layout must ensure matched gate loop inductance (<5 nH difference) and symmetrical source routing to avoid dynamic imbalance during switching transitions.

Is the Max247 package RoHS-compliant and halogen-free?

Yes - ST certifies the Max247 package as ECOPACK2 compliant, meeting RoHS Directive 2011/65/EU and IEC 61249-2-21:2011 for halogen-free materials (Cl < 900 ppm, Br < 900 ppm, total halogens < 1500 ppm), as documented in ST's ECOPACK specifications portal.
